To Sherlock Holmes she is always THE woman. I have seldom heard
him mention her under any other name. In his eyes she eclipses
and predominates the whole of her sex. It was not that he felt
any emotion akin to love for Irene Adler. All emotions, and that
one particularly, were abhorrent to his cold, precise but
admirably balanced mind. He was, I take it, the most perfect
reasoning and observing machine that the world has seen, but as a
lover he would have placed himself in a false position. He never
spoke of the softer passions, save with a gibe and a sneer. They
were admirable things for the observer--excellent for drawing the
veil from men's motives and actions. But for the trained reasoner
to admit such intrusions into his own delicate and finely
adjusted temperament was to introduce a distracting factor which
might throw a doubt upon all his mental results. Grit in a
sensitive instrument, or a crack in one of his own high-power
lenses, would not be more disturbing than a strong emotion in a
nature such as his. And yet there was but one woman to him, and
that woman was the late Irene Adler, of dubious and questionable
memory.

I had seen little of Holmes lately. My marriage had drifted us
away from each other. My own complete happiness, and the
home-centred interests which rise up around the man who first
finds himself master of his own establishment, were sufficient to
absorb all my attention, while Holmes, who loathed every form of
society with his whole Bohemian soul, remained in our lodgings in
Baker Street, buried among his old books, and alternating from
week to week between cocaine and ambition, the drowsiness of the
drug, and the fierce energy of his own keen nature. He was still,
as ever, deeply attracted by the study of crime, and occupied his
immense faculties and extraordinary powers of observation in
following out those clues, and clearing up those mysteries which
had been abandoned as hopeless by the official police. From time
to time I heard some vague account of his doings: of his summons
to Odessa in the case of the Trepoff murder, of his clearing up
of the singular tragedy of the Atkinson brothers at Trincomalee,
and finally of the mission which he had accomplished so
delicately and successfully for the reigning family of Holland.
Beyond these signs of his activity, however, which I merely
shared with all the readers of the daily press, I knew little of
my former friend and companion.

One night--it was on the twentieth of March, 1888--I was
returning from a journey to a patient (for I had now returned to
civil practice), when my way led me through Baker Street. As I
passed the well-remembered door, which must always be associated
in my mind with my wooing, and with the dark incidents of the
Study in Scarlet, I was seized with a keen desire to see Holmes
again, and to know how he was employing his extraordinary powers.
His rooms were brilliantly lit, and, even as I looked up, I saw
his tall, spare figure pass twice in a dark silhouette against
the blind. He was pacing the room swiftly, eagerly, with his head
sunk upon his chest and his hands clasped behind him. To me, who
knew his every mood and habit, his attitude and manner told their
own story. He was at work again. He had risen out of his
drug-created dreams and was hot upon the scent of some new
problem. I rang the bell and was shown up to the chamber which
had formerly been in part my own.

His manner was not effusive. It seldom was; but he was glad, I
think, to see me. With hardly a word spoken, but with a kindly
eye, he waved me to an armchair, threw across his case of cigars,
and indicated a spirit case and a gasogene in the corner. Then he
stood before the fire and looked me over in his singular
introspective fashion.

"Wedlock suits you," he remarked. "I think, Watson, that you have
put on seven and a half pounds since I saw you."

"Seven!" I answered.

"Indeed, I should have thought a little more. Just a trifle more,
I fancy, Watson. And in practice again, I observe. You did not
tell me that you intended to go into harness."

"Then, how do you know?"

"I see it, I deduce it. How do I know that you have been getting
yourself very wet lately, and that you have a most clumsy and
careless servant girl?"

"My dear Holmes," said I, "this is too much. You would certainly
have been burned, had you lived a few centuries ago. It is true
that I had a country walk on Thursday and came home in a dreadful
mess, but as I have changed my clothes I can't imagine how you
deduce it. As to Mary Jane, she is incorrigible, and my wife has
given her notice, but there, again, I fail to see how you work it
out."

He chuckled to himself and rubbed his long, nervous hands
together.

"It is simplicity itself," said he; "my eyes tell me that on the
inside of your left shoe, just where the firelight strikes it,
the leather is scored by six almost parallel cuts. Obviously they
have been caused by someone who has very carelessly scraped round
the edges of the sole in order to remove crusted mud from it.
Hence, you see, my double deduction that you had been out in vile
weather, and that you had a particularly malignant boot-slitting
specimen of the London slavey. As to your practice, if a
gentleman walks into my rooms smelling of iodoform, with a black
mark of nitrate of silver upon his right forefinger, and a bulge
on the right side of his top-hat to show where he has secreted
his stethoscope, I must be dull, indeed, if I do not pronounce
him to be an active member of the medical profession."

I could not help laughing at the ease with which he explained his
process of deduction. "When I hear you give your reasons," I
remarked, "the thing always appears to me to be so ridiculously
simple that I could easily do it myself, though at each
successive instance of your reasoning I am baffled until you
explain your process. And yet I believe that my eyes are as good
as yours."

"Quite so," he answered, lighting a cigarette, and throwing
himself down into an armchair. "You see, but you do not observe.
The distinction is clear. For example, you have frequently seen
the steps which lead up from the hall to this room."

"Frequently."

"How often?"

"Well, some hundreds of times."

"Then how many are there?"

"How many? I don't know."

"Quite so! You have not observed. And yet you have seen. That is
just my point. Now, I know that there are seventeen steps,
because I have both seen and observed. By-the-way, since you are
interested in these little problems, and since you are good
enough to chronicle one or two of my trifling experiences, you
may be interested in this." He threw over a sheet of thick,
pink-tinted note-paper which had been lying open upon the table.
"It came by the last post," said he. "Read it aloud."

The note was undated, and without either signature or address.

"There will call upon you to-night, at a quarter to eight
o'clock," it said, "a gentleman who desires to consult you upon a
matter of the very deepest moment. Your recent services to one of
the royal houses of Europe have shown that you are one who may
safely be trusted with matters which are of an importance which
can hardly be exaggerated. This account of you we have from all
quarters received. Be in your chamber then at that hour, and do
not take it amiss if your visitor wear a mask."

"This is indeed a mystery," I remarked. "What do you imagine that
it means?"

"I have no data yet. It is a capital mistake to theorize before
one has data. Insensibly one begins to twist facts to suit
theories, instead of theories to suit facts. But the note itself.
What do you deduce from it?"

I carefully examined the writing, and the paper upon which it was
written.

"The man who wrote it was presumably well to do," I remarked,
endeavouring to imitate my companion's processes. "Such paper
could not be bought under half a crown a packet. It is peculiarly
strong and stiff."

"Peculiar--that is the very word," said Holmes. "It is not an
English paper at all. Hold it up to the light."

I did so, and saw a large "E" with a small "g," a "P," and a
large "G" with a small "t" woven into the texture of the paper.

"What do you make of that?" asked Holmes.

"The name of the maker, no doubt; or his monogram, rather."

"Not at all. The 'G' with the small 't' stands for
'Gesellschaft,' which is the German for 'Company.' It is a
customary contraction like our 'Co.' 'P,' of course, stands for
'Papier.' Now for the 'Eg.' Let us glance at our Continental
Gazetteer." He took down a heavy brown volume from his shelves.
"Eglow, Eglonitz--here we are, Egria. It is in a German-speaking
country--in Bohemia, not far from Carlsbad. 'Remarkable as being
the scene of the death of Wallenstein, and for its numerous
glass-factories and paper-mills.' Ha, ha, my boy, what do you
make of that?" His eyes sparkled, and he sent up a great blue
triumphant cloud from his cigarette.

"The paper was made in Bohemia," I said.

"Precisely. And the man who wrote the note is a German. Do you
note the peculiar construction of the sentence--'This account of
you we have from all quarters received.' A Frenchman or Russian
could not have written that. It is the German who is so
uncourteous to his verbs. It only remains, therefore, to discover
what is wanted by this German who writes upon Bohemian paper and
prefers wearing a mask to showing his face. And here he comes, if
I am not mistaken, to resolve all our doubts."

As he spoke there was the sharp sound of horses' hoofs and
grating wheels against the curb, followed by a sharp pull at the
bell. Holmes whistled.

"A pair, by the sound," said he. "Yes," he continued, glancing
out of the window. "A nice little brougham and a pair of
beauties. A hundred and fifty guineas apiece. There's money in
this case, Watson, if there is nothing else."

"I think that I had better go, Holmes."

"Not a bit, Doctor. Stay where you are. I am lost without my
Boswell. And this promises to be interesting. It would be a pity
to miss it."

"But your client--"

"Never mind him. I may want your help, and so may he. Here he
comes. Sit down in that armchair, Doctor, and give us your best
attention."

A slow and heavy step, which had been heard upon the stairs and
in the passage, paused immediately outside the door. Then there
was a loud and authoritative tap.

"Come in!" said Holmes.

A man entered who could hardly have been less than six feet six
inches in height, with the chest and limbs of a Hercules. His
dress was rich with a richness which would, in England, be looked
upon as akin to bad taste. Heavy bands of astrakhan were slashed
across the sleeves and fronts of his double-breasted coat, while
the deep blue cloak which was thrown over his shoulders was lined
with flame-coloured silk and secured at the neck with a brooch
which consisted of a single flaming beryl. Boots which extended
halfway up his calves, and which were trimmed at the tops with
rich brown fur, completed the impression of barbaric opulence
which was suggested by his whole appearance. He carried a
broad-brimmed hat in his hand, while he wore across the upper
part of his face, extending down past the cheekbones, a black
vizard mask, which he had apparently adjusted that very moment,
for his hand was still raised to it as he entered. From the lower
part of the face he appeared to be a man of strong character,
with a thick, hanging lip, and a long, straight chin suggestive
of resolution pushed to the length of obstinacy.

"You had my note?" he asked with a deep harsh voice and a
strongly marked German accent. "I told you that I would call." He
looked from one to the other of us, as if uncertain which to
address.

"Pray take a seat," said Holmes. "This is my friend and
colleague, Dr. Watson, who is occasionally good enough to help me
in my cases. Whom have I the honour to address?"

"You may address me as the Count Von Kramm, a Bohemian nobleman.
I understand that this gentleman, your friend, is a man of honour
and discretion, whom I may trust with a matter of the most
extreme importance. If not, I should much prefer to communicate
with you alone."

I rose to go, but Holmes caught me by the wrist and pushed me
back into my chair. "It is both, or none," said he. "You may say
before this gentleman anything which you may say to me."

The Count shrugged his broad shoulders. "Then I must begin," said
he, "by binding you both to absolute secrecy for two years; at
the end of that time the matter will be of no importance. At
present it is not too much to say that it is of such weight it
may have an influence upon European history."

"I promise," said Holmes.

"And I."

"You will excuse this mask," continued our strange visitor. "The
august person who employs me wishes his agent to be unknown to
you, and I may confess at once that the title by which I have
just called myself is not exactly my own."

"I was aware of it," said Holmes dryly.

"The circumstances are of great delicacy, and every precaution
has to be taken to quench what might grow to be an immense
scandal and seriously compromise one of the reigning families of
Europe. To speak plainly, the matter implicates the great House
of Ormstein, hereditary kings of Bohemia."

"I was also aware of that," murmured Holmes, settling himself
down in his armchair and closing his eyes.

Our visitor glanced with some apparent surprise at the languid,
lounging figure of the man who had been no doubt depicted to him
as the most incisive reasoner and most energetic agent in Europe.
Holmes slowly reopened his eyes and looked impatiently at his
gigantic client.

"If your Majesty would condescend to state your case," he
remarked, "I should be better able to advise you."

The man sprang from his chair and paced up and down the room in
uncontrollable agitation. Then, with a gesture of desperation, he
tore the mask from his face and hurled it upon the ground. "You
are right," he cried; "I am the King. Why should I attempt to
conceal it?"

"Why, indeed?" murmured Holmes. "Your Majesty had not spoken
before I was aware that I was addressing Wilhelm Gottsreich
Sigismond von Ormstein, Grand Duke of Cassel-Felstein, and
hereditary King of Bohemia."

"But you can understand," said our strange visitor, sitting down
once more and passing his hand over his high white forehead, "you
can understand that I am not accustomed to doing such business in
my own person. Yet the matter was so delicate that I could not
confide it to an agent without putting myself in his power. I
have come incognito from Prague for the purpose of consulting
you."

"Then, pray consult," said Holmes, shutting his eyes once more.

"The facts are briefly these: Some five years ago, during a
lengthy visit to Warsaw, I made the acquaintance of the well-known
adventuress, Irene Adler. The name is no doubt familiar to you."

"Kindly look her up in my index, Doctor," murmured Holmes without
opening his eyes. For many years he had adopted a system of
docketing all paragraphs concerning men and things, so that it
was difficult to name a subject or a person on which he could not
at once furnish information. In this case I found her biography
sandwiched in between that of a Hebrew rabbi and that of a
staff-commander who had written a monograph upon the deep-sea
fishes.

"Let me see!" said Holmes. "Hum! Born in New Jersey in the year
1858. Contralto--hum! La Scala, hum! Prima donna Imperial Opera
of Warsaw--yes! Retired from operatic stage--ha! Living in
London--quite so! Your Majesty, as I understand, became entangled
with this young person, wrote her some compromising letters, and
is now desirous of getting those letters back."

"Precisely so. But how--"

"Was there a secret marriage?"

"None."

"No legal papers or certificates?"

"None."

"Then I fail to follow your Majesty. If this young person should
produce her letters for blackmailing or other purposes, how is
she to prove their authenticity?"

"There is the writing."

"Pooh, pooh! Forgery."

"My private note-paper."

"Stolen."

"My own seal."

"Imitated."

"My photograph."

"Bought."

"We were both in the photograph."

"Oh, dear! That is very bad! Your Majesty has indeed committed an
indiscretion."

"I was mad--insane."

"You have compromised yourself seriously."

"I was only Crown Prince then. I was young. I am but thirty now."

"It must be recovered."

"We have tried and failed."

"Your Majesty must pay. It must be bought."

"She will not sell."

"Stolen, then."

"Five attempts have been made. Twice burglars in my pay ransacked
her house. Once we diverted her luggage when she travelled. Twice
she has been waylaid. There has been no result."

"No sign of it?"

"Absolutely none."

Holmes laughed. "It is quite a pretty little problem," said he.

"But a very serious one to me," returned the King reproachfully.

"Very, indeed. And what does she propose to do with the
photograph?"

"To ruin me."

"But how?"

"I am about to be married."

"So I have heard."

"To Clotilde Lothman von Saxe-Meningen, second daughter of the
King of Scandinavia. You may know the strict principles of her
family. She is herself the very soul of delicacy. A shadow of a
doubt as to my conduct would bring the matter to an end."

"And Irene Adler?"

"Threatens to send them the photograph. And she will do it. I
know that she will do it. You do not know her, but she has a soul
of steel. She has the face of the most beautiful of women, and
the mind of the most resolute of men. Rather than I should marry
another woman, there are no lengths to which she would not
go--none."

"You are sure that she has not sent it yet?"

"I am sure."

"And why?"

"Because she has said that she would send it on the day when the
betrothal was publicly proclaimed. That will be next Monday."

"Oh, then we have three days yet," said Holmes with a yawn. "That
is very fortunate, as I have one or two matters of importance to
look into just at present. Your Majesty will, of course, stay in
London for the present?"

"Certainly. You will find me at the Langham under the name of the
Count Von Kramm."

"Then I shall drop you a line to let you know how we progress."

"Pray do so. I shall be all anxiety."

"Then, as to money?"

"You have carte blanche."

"Absolutely?"

"I tell you that I would give one of the provinces of my kingdom
to have that photograph."

"And for present expenses?"

The King took a heavy chamois leather bag from under his cloak
and laid it on the table.

"There are three hundred pounds in gold and seven hundred in
notes," he said.

Holmes scribbled a receipt upon a sheet of his note-book and
handed it to him.

"And Mademoiselle's address?" he asked.

"Is Briony Lodge, Serpentine Avenue, St. John's Wood."

Holmes took a note of it. "One other question," said he. "Was the
photograph a cabinet?"

"It was."

"Then, good-night, your Majesty, and I trust that we shall soon
have some good news for you. And good-night, Watson," he added,
as the wheels of the royal brougham rolled down the street. "If
you will be good enough to call to-morrow afternoon at three
o'clock I should like to chat this little matter over with you."
"""

bohemia_ch2 = """
At three o'clock precisely I was at Baker Street, but Holmes had
not yet returned. The landlady informed me that he had left the
house shortly after eight o'clock in the morning. I sat down
beside the fire, however, with the intention of awaiting him,
however long he might be. I was already deeply interested in his
inquiry, for, though it was surrounded by none of the grim and
strange features which were associated with the two crimes which
I have already recorded, still, the nature of the case and the
exalted station of his client gave it a character of its own.
Indeed, apart from the nature of the investigation which my
friend had on hand, there was something in his masterly grasp of
a situation, and his keen, incisive reasoning, which made it a
pleasure to me to study his system of work, and to follow the
quick, subtle methods by which he disentangled the most
inextricable mysteries. So accustomed was I to his invariable
success that the very possibility of his failing had ceased to
enter into my head.

It was close upon four before the door opened, and a
drunken-looking groom, ill-kempt and side-whiskered, with an
inflamed face and disreputable clothes, walked into the room.
Accustomed as I was to my friend's amazing powers in the use of
disguises, I had to look three times before I was certain that it
was indeed he. With a nod he vanished into the bedroom, whence he
emerged in five minutes tweed-suited and respectable, as of old.
Putting his hands into his pockets, he stretched out his legs in
front of the fire and laughed heartily for some minutes.

"Well, really!" he cried, and then he choked and laughed again
until he was obliged to lie back, limp and helpless, in the
chair.

"What is it?"

"It's quite too funny. I am sure you could never guess how I
employed my morning, or what I ended by doing."

"I can't imagine. I suppose that you have been watching the
habits, and perhaps the house, of Miss Irene Adler."

"Quite so; but the sequel was rather unusual. I will tell you,
however. I left the house a little after eight o'clock this
morning in the character of a groom out of work. There is a
wonderful sympathy and freemasonry among horsey men. Be one of
them, and you will know all that there is to know. I soon found
Briony Lodge. It is a bijou villa, with a garden at the back, but
built out in front right up to the road, two stories. Chubb lock
to the door. Large sitting-room on the right side, well
furnished, with long windows almost to the floor, and those
preposterous English window fasteners which a child could open.
Behind there was nothing remarkable, save that the passage window
could be reached from the top of the coach-house. I walked round
it and examined it closely from every point of view, but without
noting anything else of interest.

"I then lounged down the street and found, as I expected, that
there was a mews in a lane which runs down by one wall of the
garden. I lent the ostlers a hand in rubbing down their horses,
and received in exchange twopence, a glass of half and half, two
fills of shag tobacco, and as much information as I could desire
about Miss Adler, to say nothing of half a dozen other people in
the neighbourhood in whom I was not in the least interested, but
whose biographies I was compelled to listen to."

"And what of Irene Adler?" I asked.

"Oh, she has turned all the men's heads down in that part. She is
the daintiest thing under a bonnet on this planet. So say the
Serpentine-mews, to a man. She lives quietly, sings at concerts,
drives out at five every day, and returns at seven sharp for
dinner. Seldom goes out at other times, except when she sings.
Has only one male visitor, but a good deal of him. He is dark,
handsome, and dashing, never calls less than once a day, and
often twice. He is a Mr. Godfrey Norton, of the Inner Temple. See
the advantages of a cabman as a confidant. They had driven him
home a dozen times from Serpentine-mews, and knew all about him.
When I had listened to all they had to tell, I began to walk up
and down near Briony Lodge once more, and to think over my plan
of campaign.

"This Godfrey Norton was evidently an important factor in the
matter. He was a lawyer. That sounded ominous. What was the
relation between them, and what the object of his repeated
visits? Was she his client, his friend, or his mistress? If the
former, she had probably transferred the photograph to his
keeping. If the latter, it was less likely. On the issue of this
question depended whether I should continue my work at Briony
Lodge, or turn my attention to the gentleman's chambers in the
Temple. It was a delicate point, and it widened the field of my
inquiry. I fear that I bore you with these details, but I have to
let you see my little difficulties, if you are to understand the
situation."

"I am following you closely," I answered.

"I was still balancing the matter in my mind when a hansom cab
drove up to Briony Lodge, and a gentleman sprang out. He was a
remarkably handsome man, dark, aquiline, and moustached--evidently
the man of whom I had heard. He appeared to be in a
great hurry, shouted to the cabman to wait, and brushed past the
maid who opened the door with the air of a man who was thoroughly
at home.

"He was in the house about half an hour, and I could catch
glimpses of him in the windows of the sitting-room, pacing up and
down, talking excitedly, and waving his arms. Of her I could see
nothing. Presently he emerged, looking even more flurried than
before. As he stepped up to the cab, he pulled a gold watch from
his pocket and looked at it earnestly, 'Drive like the devil,' he
shouted, 'first to Gross & Hankey's in Regent Street, and then to
the Church of St. Monica in the Edgeware Road. Half a guinea if
you do it in twenty minutes!'

"Away they went, and I was just wondering whether I should not do
well to follow them when up the lane came a neat little landau,
the coachman with his coat only half-buttoned, and his tie under
his ear, while all the tags of his harness were sticking out of
the buckles. It hadn't pulled up before she shot out of the hall
door and into it. I only caught a glimpse of her at the moment,
but she was a lovely woman, with a face that a man might die for.

"'The Church of St. Monica, John,' she cried, 'and half a
sovereign if you reach it in twenty minutes.'

"This was quite too good to lose, Watson. I was just balancing
whether I should run for it, or whether I should perch behind her
landau when a cab came through the street. The driver looked
twice at such a shabby fare, but I jumped in before he could
object. 'The Church of St. Monica,' said I, 'and half a sovereign
if you reach it in twenty minutes.' It was twenty-five minutes to
twelve, and of course it was clear enough what was in the wind.

"My cabby drove fast. I don't think I ever drove faster, but the
others were there before us. The cab and the landau with their
steaming horses were in front of the door when I arrived. I paid
the man and hurried into the church. There was not a soul there
save the two whom I had followed and a surpliced clergyman, who
seemed to be expostulating with them. They were all three
standing in a knot in front of the altar. I lounged up the side
aisle like any other idler who has dropped into a church.
Suddenly, to my surprise, the three at the altar faced round to
me, and Godfrey Norton came running as hard as he could towards
me.

"'Thank God,' he cried. 'You'll do. Come! Come!'

"'What then?' I asked.

"'Come, man, come, only three minutes, or it won't be legal.'

"I was half-dragged up to the altar, and before I knew where I was
I found myself mumbling responses which were whispered in my ear,
and vouching for things of which I knew nothing, and generally
assisting in the secure tying up of Irene Adler, spinster, to
Godfrey Norton, bachelor. It was all done in an instant, and
there was the gentleman thanking me on the one side and the lady
on the other, while the clergyman beamed on me in front. It was
the most preposterous position in which I ever found myself in my
life, and it was the thought of it that started me laughing just
now. It seems that there had been some informality about their
license, that the clergyman absolutely refused to marry them
without a witness of some sort, and that my lucky appearance
saved the bridegroom from having to sally out into the streets in
search of a best man. The bride gave me a sovereign, and I mean
to wear it on my watch-chain in memory of the occasion."

"This is a very unexpected turn of affairs," said I; "and what
then?"

"Well, I found my plans very seriously menaced. It looked as if
the pair might take an immediate departure, and so necessitate
very prompt and energetic measures on my part. At the church
door, however, they separated, he driving back to the Temple, and
she to her own house. 'I shall drive out in the park at five as
usual,' she said as she left him. I heard no more. They drove
away in different directions, and I went off to make my own
arrangements."

"Which are?"

"Some cold beef and a glass of beer," he answered, ringing the
bell. "I have been too busy to think of food, and I am likely to
be busier still this evening. By the way, Doctor, I shall want
your co-operation."

"I shall be delighted."

"You don't mind breaking the law?"

"Not in the least."

"Nor running a chance of arrest?"

"Not in a good cause."

"Oh, the cause is excellent!"

"Then I am your man."

"I was sure that I might rely on you."

"But what is it you wish?"

"When Mrs. Turner has brought in the tray I will make it clear to
you. Now," he said as he turned hungrily on the simple fare that
our landlady had provided, "I must discuss it while I eat, for I
have not much time. It is nearly five now. In two hours we must
be on the scene of action. Miss Irene, or Madame, rather, returns
from her drive at seven. We must be at Briony Lodge to meet her."

"And what then?"

"You must leave that to me. I have already arranged what is to
occur. There is only one point on which I must insist. You must
not interfere, come what may. You understand?"

"I am to be neutral?"

"To do nothing whatever. There will probably be some small
unpleasantness. Do not join in it. It will end in my being
conveyed into the house. Four or five minutes afterwards the
sitting-room window will open. You are to station yourself close
to that open window."

"Yes."

"You are to watch me, for I will be visible to you."

"Yes."

"And when I raise my hand--so--you will throw into the room what
I give you to throw, and will, at the same time, raise the cry of
fire. You quite follow me?"

"Entirely."

"It is nothing very formidable," he said, taking a long cigar-shaped
roll from his pocket. "It is an ordinary plumber's smoke-rocket,
fitted with a cap at either end to make it self-lighting.
Your task is confined to that. When you raise your cry of fire,
it will be taken up by quite a number of people. You may then
walk to the end of the street, and I will rejoin you in ten
minutes. I hope that I have made myself clear?"

"I am to remain neutral, to get near the window, to watch you,
and at the signal to throw in this object, then to raise the cry
of fire, and to wait you at the corner of the street."

"Precisely."

"Then you may entirely rely on me."

"That is excellent. I think, perhaps, it is almost time that I
prepare for the new role I have to play."

He disappeared into his bedroom and returned in a few minutes in
the character of an amiable and simple-minded Nonconformist
clergyman. His broad black hat, his baggy trousers, his white
tie, his sympathetic smile, and general look of peering and
benevolent curiosity were such as Mr. John Hare alone could have
equalled. It was not merely that Holmes changed his costume. His
expression, his manner, his very soul seemed to vary with every
fresh part that he assumed. The stage lost a fine actor, even as
science lost an acute reasoner, when he became a specialist in
crime.

It was a quarter past six when we left Baker Street, and it still
wanted ten minutes to the hour when we found ourselves in
Serpentine Avenue. It was already dusk, and the lamps were just
being lighted as we paced up and down in front of Briony Lodge,
waiting for the coming of its occupant. The house was just such
as I had pictured it from Sherlock Holmes' succinct description,
but the locality appeared to be less private than I expected. On
the contrary, for a small street in a quiet neighbourhood, it was
remarkably animated. There was a group of shabbily dressed men
smoking and laughing in a corner, a scissors-grinder with his
wheel, two guardsmen who were flirting with a nurse-girl, and
several well-dressed young men who were lounging up and down with
cigars in their mouths.

"You see," remarked Holmes, as we paced to and fro in front of
the house, "this marriage rather simplifies matters. The
photograph becomes a double-edged weapon now. The chances are
that she would be as averse to its being seen by Mr. Godfrey
Norton, as our client is to its coming to the eyes of his
princess. Now the question is, Where are we to find the
photograph?"

"Where, indeed?"

"It is most unlikely that she carries it about with her. It is
cabinet size. Too large for easy concealment about a woman's
dress. She knows that the King is capable of having her waylaid
and searched. Two attempts of the sort have already been made. We
may take it, then, that she does not carry it about with her."

"Where, then?"

"Her banker or her lawyer. There is that double possibility. But
I am inclined to think neither. Women are naturally secretive,
and they like to do their own secreting. Why should she hand it
over to anyone else? She could trust her own guardianship, but
she could not tell what indirect or political influence might be
brought to bear upon a business man. Besides, remember that she
had resolved to use it within a few days. It must be where she
can lay her hands upon it. It must be in her own house."

"But it has twice been burgled."

"Pshaw! They did not know how to look."

"But how will you look?"

"I will not look."

"What then?"

"I will get her to show me."

"But she will refuse."

"She will not be able to. But I hear the rumble of wheels. It is
her carriage. Now carry out my orders to the letter."

As he spoke the gleam of the side-lights of a carriage came round
the curve of the avenue. It was a smart little landau which
rattled up to the door of Briony Lodge. As it pulled up, one of
the loafing men at the corner dashed forward to open the door in
the hope of earning a copper, but was elbowed away by another
loafer, who had rushed up with the same intention. A fierce
quarrel broke out, which was increased by the two guardsmen, who
took sides with one of the loungers, and by the scissors-grinder,
who was equally hot upon the other side. A blow was struck, and
in an instant the lady, who had stepped from her carriage, was
the centre of a little knot of flushed and struggling men, who
struck savagely at each other with their fists and sticks. Holmes
dashed into the crowd to protect the lady; but just as he reached
her he gave a cry and dropped to the ground, with the blood
running freely down his face. At his fall the guardsmen took to
their heels in one direction and the loungers in the other, while
a number of better-dressed people, who had watched the scuffle
without taking part in it, crowded in to help the lady and to
attend to the injured man. Irene Adler, as I will still call her,
had hurried up the steps; but she stood at the top with her
superb figure outlined against the lights of the hall, looking
back into the street.

"Is the poor gentleman much hurt?" she asked.

"He is dead," cried several voices.

"No, no, there's life in him!" shouted another. "But he'll be
gone before you can get him to hospital."

"He's a brave fellow," said a woman. "They would have had the
lady's purse and watch if it hadn't been for him. They were a
gang, and a rough one, too. Ah, he's breathing now."

"He can't lie in the street. May we bring him in, marm?"

"Surely. Bring him into the sitting-room. There is a comfortable
sofa. This way, please!"

Slowly and solemnly he was borne into Briony Lodge and laid out
in the principal room, while I still observed the proceedings
from my post by the window. The lamps had been lit, but the
blinds had not been drawn, so that I could see Holmes as he lay
upon the couch. I do not know whether he was seized with
compunction at that moment for the part he was playing, but I
know that I never felt more heartily ashamed of myself in my life
than when I saw the beautiful creature against whom I was
conspiring, or the grace and kindliness with which she waited
upon the injured man. And yet it would be the blackest treachery
to Holmes to draw back now from the part which he had intrusted
to me. I hardened my heart, and took the smoke-rocket from under
my ulster. After all, I thought, we are not injuring her. We are
but preventing her from injuring another.

Holmes had sat up upon the couch, and I saw him motion like a man
who is in need of air. A maid rushed across and threw open the
window. At the same instant I saw him raise his hand and at the
signal I tossed my rocket into the room with a cry of "Fire!" The
word was no sooner out of my mouth than the whole crowd of
spectators, well dressed and ill--gentlemen, ostlers, and
servant-maids--joined in a general shriek of "Fire!" Thick clouds
of smoke curled through the room and out at the open window. I
caught a glimpse of rushing figures, and a moment later the voice
of Holmes from within assuring them that it was a false alarm.
Slipping through the shouting crowd I made my way to the corner
of the street, and in ten minutes was rejoiced to find my
friend's arm in mine, and to get away from the scene of uproar.
He walked swiftly and in silence for some few minutes until we
had turned down one of the quiet streets which lead towards the
Edgeware Road.

"You did it very nicely, Doctor," he remarked. "Nothing could
have been better. It is all right."

"You have the photograph?"

"I know where it is."

"And how did you find out?"

"She showed me, as I told you she would."

"I am still in the dark."

"I do not wish to make a mystery," said he, laughing. "The matter
was perfectly simple. You, of course, saw that everyone in the
street was an accomplice. They were all engaged for the evening."

"I guessed as much."

"Then, when the row broke out, I had a little moist red paint in
the palm of my hand. I rushed forward, fell down, clapped my hand
to my face, and became a piteous spectacle. It is an old trick."

"That also I could fathom."

"Then they carried me in. She was bound to have me in. What else
could she do? And into her sitting-room, which was the very room
which I suspected. It lay between that and her bedroom, and I was
determined to see which. They laid me on a couch, I motioned for
air, they were compelled to open the window, and you had your
chance."

"How did that help you?"

"It was all-important. When a woman thinks that her house is on
fire, her instinct is at once to rush to the thing which she
values most. It is a perfectly overpowering impulse, and I have
more than once taken advantage of it. In the case of the
Darlington substitution scandal it was of use to me, and also in
the Arnsworth Castle business. A married woman grabs at her baby;
an unmarried one reaches for her jewel-box. Now it was clear to
me that our lady of to-day had nothing in the house more precious
to her than what we are in quest of. She would rush to secure it.
The alarm of fire was admirably done. The smoke and shouting were
enough to shake nerves of steel. She responded beautifully. The
photograph is in a recess behind a sliding panel just above the
right bell-pull. She was there in an instant, and I caught a
glimpse of it as she half-drew it out. When I cried out that it
was a false alarm, she replaced it, glanced at the rocket, rushed
from the room, and I have not seen her since. I rose, and, making
my excuses, escaped from the house. I hesitated whether to
attempt to secure the photograph at once; but the coachman had
come in, and as he was watching me narrowly it seemed safer to
wait. A little over-precipitance may ruin all."

"And now?" I asked.

"Our quest is practically finished. I shall call with the King
to-morrow, and with you, if you care to come with us. We will be
shown into the sitting-room to wait for the lady, but it is
probable that when she comes she may find neither us nor the
photograph. It might be a satisfaction to his Majesty to regain
it with his own hands."

"And when will you call?"

"At eight in the morning. She will not be up, so that we shall
have a clear field. Besides, we must be prompt, for this marriage
may mean a complete change in her life and habits. I must wire to
the King without delay."

We had reached Baker Street and had stopped at the door. He was
searching his pockets for the key when someone passing said:

"Good-night, Mister Sherlock Holmes."

There were several people on the pavement at the time, but the
greeting appeared to come from a slim youth in an ulster who had
hurried by.

"I've heard that voice before," said Holmes, staring down the
dimly lit street. "Now, I wonder who the deuce that could have
been."
"""

bohemia_ch3 = """
I slept at Baker Street that night, and we were engaged upon our
toast and coffee in the morning when the King of Bohemia rushed
into the room.

"You have really got it!" he cried, grasping Sherlock Holmes by
either shoulder and looking eagerly into his face.

"Not yet."

"But you have hopes?"

"I have hopes."

"Then, come. I am all impatience to be gone."

"We must have a cab."

"No, my brougham is waiting."

"Then that will simplify matters." We descended and started off
once more for Briony Lodge.

"Irene Adler is married," remarked Holmes.

"Married! When?"

"Yesterday."

"But to whom?"

"To an English lawyer named Norton."

"But she could not love him."

"I am in hopes that she does."

"And why in hopes?"

"Because it would spare your Majesty all fear of future
annoyance. If the lady loves her husband, she does not love your
Majesty. If she does not love your Majesty, there is no reason
why she should interfere with your Majesty's plan."

"It is true. And yet--Well! I wish she had been of my own
station! What a queen she would have made!" He relapsed into a
moody silence, which was not broken until we drew up in
Serpentine Avenue.

The door of Briony Lodge was open, and an elderly woman stood
upon the steps. She watched us with a sardonic eye as we stepped
from the brougham.

"Mr. Sherlock Holmes, I believe?" said she.

"I am Mr. Holmes," answered my companion, looking at her with a
questioning and rather startled gaze.

"Indeed! My mistress told me that you were likely to call. She
left this morning with her husband by the 5:15 train from Charing
Cross for the Continent."

"What!" Sherlock Holmes staggered back, white with chagrin and
surprise. "Do you mean that she has left England?"

"Never to return."

"And the papers?" asked the King hoarsely. "All is lost."

"We shall see." He pushed past the servant and rushed into the
drawing-room, followed by the King and myself. The furniture was
scattered about in every direction, with dismantled shelves and
open drawers, as if the lady had hurriedly ransacked them before
her flight. Holmes rushed at the bell-pull, tore back a small
sliding shutter, and, plunging in his hand, pulled out a
photograph and a letter. The photograph was of Irene Adler
herself in evening dress, the letter was superscribed to
"Sherlock Holmes, Esq. To be left till called for." My friend
tore it open and we all three read it together. It was dated at
midnight of the preceding night and ran in this way:

"MY DEAR MR. SHERLOCK HOLMES,--You really did it very well. You
took me in completely. Until after the alarm of fire, I had not a
suspicion. But then, when I found how I had betrayed myself, I
began to think. I had been warned against you months ago. I had
been told that if the King employed an agent it would certainly
be you. And your address had been given me. Yet, with all this,
you made me reveal what you wanted to know. Even after I became
suspicious, I found it hard to think evil of such a dear, kind
old clergyman. But, you know, I have been trained as an actress
myself. Male costume is nothing new to me. I often take advantage
of the freedom which it gives. I sent John, the coachman, to
watch you, ran up stairs, got into my walking-clothes, as I call
them, and came down just as you departed.

"Well, I followed you to your door, and so made sure that I was
really an object of interest to the celebrated Mr. Sherlock
Holmes. Then I, rather imprudently, wished you good-night, and
started for the Temple to see my husband.

"We both thought the best resource was flight, when pursued by
so formidable an antagonist; so you will find the nest empty when
you call to-morrow. As to the photograph, your client may rest in
peace. I love and am loved by a better man than he. The King may
do what he will without hindrance from one whom he has cruelly
wronged. I keep it only to safeguard myself, and to preserve a
weapon which will always secure me from any steps which he might
take in the future. I leave a photograph which he might care to
possess; and I remain, dear Mr. Sherlock Holmes,

                                      "Very truly yours,
                                   "IRENE NORTON, ne ADLER."

"What a woman--oh, what a woman!" cried the King of Bohemia, when
we had all three read this epistle. "Did I not tell you how quick
and resolute she was? Would she not have made an admirable queen?
Is it not a pity that she was not on my level?"

"From what I have seen of the lady she seems indeed to be on a
very different level to your Majesty," said Holmes coldly. "I am
sorry that I have not been able to bring your Majesty's business
to a more successful conclusion."

"On the contrary, my dear sir," cried the King; "nothing could be
more successful. I know that her word is inviolate. The
photograph is now as safe as if it were in the fire."

"I am glad to hear your Majesty say so."

"I am immensely indebted to you. Pray tell me in what way I can
reward you. This ring--" He slipped an emerald snake ring from
his finger and held it out upon the palm of his hand.

"Your Majesty has something which I should value even more
highly," said Holmes.

"You have but to name it."

"This photograph!"

The King stared at him in amazement.

"Irene's photograph!" he cried. "Certainly, if you wish it."

"I thank your Majesty. Then there is no more to be done in the
matter. I have the honour to wish you a very good-morning." He
bowed, and, turning away without observing the hand which the
King had stretched out to him, he set off in my company for his
chambers.

And that was how a great scandal threatened to affect the kingdom
of Bohemia, and how the best plans of Mr. Sherlock Holmes were
beaten by a woman's wit. He used to make merry over the
cleverness of women, but I have not heard him do it of late. And
when he speaks of Irene Adler, or when he refers to her
photograph, it is always under the honourable title of the woman.
"""

boscombe_ch1 = """
We were seated at breakfast one morning, my wife and I, when the
maid brought in a telegram. It was from Sherlock Holmes and ran
in this way:

"Have you a couple of days to spare? Have just been wired for from
the west of England in connection with Boscombe Valley tragedy.
Shall be glad if you will come with me. Air and scenery perfect.
Leave Paddington by the 11:15."

"What do you say, dear?" said my wife, looking across at me.
"Will you go?"

"I really don't know what to say. I have a fairly long list at
present."

"Oh, Anstruther would do your work for you. You have been looking
a little pale lately. I think that the change would do you good,
and you are always so interested in Mr. Sherlock Holmes' cases."

"I should be ungrateful if I were not, seeing what I gained
through one of them," I answered. "But if I am to go, I must pack
at once, for I have only half an hour."

My experience of camp life in Afghanistan had at least had the
effect of making me a prompt and ready traveller. My wants were
few and simple, so that in less than the time stated I was in a
cab with my valise, rattling away to Paddington Station. Sherlock
Holmes was pacing up and down the platform, his tall, gaunt
figure made even gaunter and taller by his long grey
travelling-cloak and close-fitting cloth cap.

"It is really very good of you to come, Watson," said he. "It
makes a considerable difference to me, having someone with me on
whom I can thoroughly rely. Local aid is always either worthless
or else biassed. If you will keep the two corner seats I shall
get the tickets."

We had the carriage to ourselves save for an immense litter of
papers which Holmes had brought with him. Among these he rummaged
and read, with intervals of note-taking and of meditation, until
we were past Reading. Then he suddenly rolled them all into a
gigantic ball and tossed them up onto the rack.

"Have you heard anything of the case?" he asked.

"Not a word. I have not seen a paper for some days."

"The London press has not had very full accounts. I have just
been looking through all the recent papers in order to master the
particulars. It seems, from what I gather, to be one of those
simple cases which are so extremely difficult."

"That sounds a little paradoxical."

"But it is profoundly true. Singularity is almost invariably a
clue. The more featureless and commonplace a crime is, the more
difficult it is to bring it home. In this case, however, they
have established a very serious case against the son of the
murdered man."

"It is a murder, then?"

"Well, it is conjectured to be so. I shall take nothing for
granted until I have the opportunity of looking personally into
it. I will explain the state of things to you, as far as I have
been able to understand it, in a very few words.

"Boscombe Valley is a country district not very far from Ross, in
Herefordshire. The largest landed proprietor in that part is a
Mr. John Turner, who made his money in Australia and returned
some years ago to the old country. One of the farms which he
held, that of Hatherley, was let to Mr. Charles McCarthy, who was
also an ex-Australian. The men had known each other in the
colonies, so that it was not unnatural that when they came to
settle down they should do so as near each other as possible.
Turner was apparently the richer man, so McCarthy became his
tenant but still remained, it seems, upon terms of perfect
equality, as they were frequently together. McCarthy had one son,
a lad of eighteen, and Turner had an only daughter of the same
age, but neither of them had wives living. They appear to have
avoided the society of the neighbouring English families and to
have led retired lives, though both the McCarthys were fond of
sport and were frequently seen at the race-meetings of the
neighbourhood. McCarthy kept two servants--a man and a girl.
Turner had a considerable household, some half-dozen at the
least. That is as much as I have been able to gather about the
families. Now for the facts.

"On June 3rd, that is, on Monday last, McCarthy left his house at
Hatherley about three in the afternoon and walked down to the
Boscombe Pool, which is a small lake formed by the spreading out
of the stream which runs down the Boscombe Valley. He had been
out with his serving-man in the morning at Ross, and he had told
the man that he must hurry, as he had an appointment of
importance to keep at three. From that appointment he never came
back alive.

"From Hatherley Farm-house to the Boscombe Pool is a quarter of a
mile, and two people saw him as he passed over this ground. One
was an old woman, whose name is not mentioned, and the other was
William Crowder, a game-keeper in the employ of Mr. Turner. Both
these witnesses depose that Mr. McCarthy was walking alone. The
game-keeper adds that within a few minutes of his seeing Mr.
McCarthy pass he had seen his son, Mr. James McCarthy, going the
same way with a gun under his arm. To the best of his belief, the
father was actually in sight at the time, and the son was
following him. He thought no more of the matter until he heard in
the evening of the tragedy that had occurred.

"The two McCarthys were seen after the time when William Crowder,
the game-keeper, lost sight of them. The Boscombe Pool is thickly
wooded round, with just a fringe of grass and of reeds round the
edge. A girl of fourteen, Patience Moran, who is the daughter of
the lodge-keeper of the Boscombe Valley estate, was in one of the
woods picking flowers. She states that while she was there she
saw, at the border of the wood and close by the lake, Mr.
McCarthy and his son, and that they appeared to be having a
violent quarrel. She heard Mr. McCarthy the elder using very
strong language to his son, and she saw the latter raise up his
hand as if to strike his father. She was so frightened by their
violence that she ran away and told her mother when she reached
home that she had left the two McCarthys quarrelling near
Boscombe Pool, and that she was afraid that they were going to
fight. She had hardly said the words when young Mr. McCarthy came
running up to the lodge to say that he had found his father dead
in the wood, and to ask for the help of the lodge-keeper. He was
much excited, without either his gun or his hat, and his right
hand and sleeve were observed to be stained with fresh blood. On
following him they found the dead body stretched out upon the
grass beside the pool. The head had been beaten in by repeated
blows of some heavy and blunt weapon. The injuries were such as
might very well have been inflicted by the butt-end of his son's
gun, which was found lying on the grass within a few paces of the
body. Under these circumstances the young man was instantly
arrested, and a verdict of 'wilful murder' having been returned
at the inquest on Tuesday, he was on Wednesday brought before the
magistrates at Ross, who have referred the case to the next
Assizes. Those are the main facts of the case as they came out
before the coroner and the police-court."

"I could hardly imagine a more damning case," I remarked. "If
ever circumstantial evidence pointed to a criminal it does so
here."

"Circumstantial evidence is a very tricky thing," answered Holmes
thoughtfully. "It may seem to point very straight to one thing,
but if you shift your own point of view a little, you may find it
pointing in an equally uncompromising manner to something
entirely different. It must be confessed, however, that the case
looks exceedingly grave against the young man, and it is very
possible that he is indeed the culprit. There are several people
in the neighbourhood, however, and among them Miss Turner, the
daughter of the neighbouring landowner, who believe in his
innocence, and who have retained Lestrade, whom you may recollect
in connection with the Study in Scarlet, to work out the case in
his interest. Lestrade, being rather puzzled, has referred the
case to me, and hence it is that two middle-aged gentlemen are
flying westward at fifty miles an hour instead of quietly
digesting their breakfasts at home."

"I am afraid," said I, "that the facts are so obvious that you
will find little credit to be gained out of this case."

"There is nothing more deceptive than an obvious fact," he
answered, laughing. "Besides, we may chance to hit upon some
other obvious facts which may have been by no means obvious to
Mr. Lestrade. You know me too well to think that I am boasting
when I say that I shall either confirm or destroy his theory by
means which he is quite incapable of employing, or even of
understanding. To take the first example to hand, I very clearly
perceive that in your bedroom the window is upon the right-hand
side, and yet I question whether Mr. Lestrade would have noted
even so self-evident a thing as that."

"How on earth--"

"My dear fellow, I know you well. I know the military neatness
which characterises you. You shave every morning, and in this
season you shave by the sunlight; but since your shaving is less
and less complete as we get farther back on the left side, until
it becomes positively slovenly as we get round the angle of the
jaw, it is surely very clear that that side is less illuminated
than the other. I could not imagine a man of your habits looking
at himself in an equal light and being satisfied with such a
result. I only quote this as a trivial example of observation and
inference. Therein lies my mtier, and it is just possible that
it may be of some service in the investigation which lies before
us. There are one or two minor points which were brought out in
the inquest, and which are worth considering."

"What are they?"

"It appears that his arrest did not take place at once, but after
the return to Hatherley Farm. On the inspector of constabulary
informing him that he was a prisoner, he remarked that he was not
surprised to hear it, and that it was no more than his deserts.
This observation of his had the natural effect of removing any
traces of doubt which might have remained in the minds of the
coroner's jury."

"It was a confession," I ejaculated.

"No, for it was followed by a protestation of innocence."

"Coming on the top of such a damning series of events, it was at
least a most suspicious remark."

"On the contrary," said Holmes, "it is the brightest rift which I
can at present see in the clouds. However innocent he might be,
he could not be such an absolute imbecile as not to see that the
circumstances were very black against him. Had he appeared
surprised at his own arrest, or feigned indignation at it, I
should have looked upon it as highly suspicious, because such
surprise or anger would not be natural under the circumstances,
and yet might appear to be the best policy to a scheming man. His
frank acceptance of the situation marks him as either an innocent
man, or else as a man of considerable self-restraint and
firmness. As to his remark about his deserts, it was also not
unnatural if you consider that he stood beside the dead body of
his father, and that there is no doubt that he had that very day
so far forgotten his filial duty as to bandy words with him, and
even, according to the little girl whose evidence is so
important, to raise his hand as if to strike him. The
self-reproach and contrition which are displayed in his remark
appear to me to be the signs of a healthy mind rather than of a
guilty one."

I shook my head. "Many men have been hanged on far slighter
evidence," I remarked.

"So they have. And many men have been wrongfully hanged."

"What is the young man's own account of the matter?"

"It is, I am afraid, not very encouraging to his supporters,
though there are one or two points in it which are suggestive.
You will find it here, and may read it for yourself."

He picked out from his bundle a copy of the local Herefordshire
paper, and having turned down the sheet he pointed out the
paragraph in which the unfortunate young man had given his own
statement of what had occurred. I settled myself down in the
corner of the carriage and read it very carefully. It ran in this
way:

"Mr. James McCarthy, the only son of the deceased, was then called
and gave evidence as follows: 'I had been away from home for
three days at Bristol, and had only just returned upon the
morning of last Monday, the 3rd. My father was absent from home at
the time of my arrival, and I was informed by the maid that he
had driven over to Ross with John Cobb, the groom. Shortly after
my return I heard the wheels of his trap in the yard, and,
looking out of my window, I saw him get out and walk rapidly out
of the yard, though I was not aware in which direction he was
going. I then took my gun and strolled out in the direction of
the Boscombe Pool, with the intention of visiting the rabbit
warren which is upon the other side. On my way I saw William
Crowder, the game-keeper, as he had stated in his evidence; but
he is mistaken in thinking that I was following my father. I had
no idea that he was in front of me. When about a hundred yards
from the pool I heard a cry of "Cooee!" which was a usual signal
between my father and myself. I then hurried forward, and found
him standing by the pool. He appeared to be much surprised at
seeing me and asked me rather roughly what I was doing there. A
conversation ensued which led to high words and almost to blows,
for my father was a man of a very violent temper. Seeing that his
passion was becoming ungovernable, I left him and returned
towards Hatherley Farm. I had not gone more than 150 yards,
however, when I heard a hideous outcry behind me, which caused me
to run back again. I found my father expiring upon the ground,
with his head terribly injured. I dropped my gun and held him in
my arms, but he almost instantly expired. I knelt beside him for
some minutes, and then made my way to Mr. Turner's lodge-keeper,
his house being the nearest, to ask for assistance. I saw no one
near my father when I returned, and I have no idea how he came by
his injuries. He was not a popular man, being somewhat cold and
forbidding in his manners, but he had, as far as I know, no
active enemies. I know nothing further of the matter.'

"The Coroner: Did your father make any statement to you before
he died?

"Witness: He mumbled a few words, but I could only catch some
allusion to a rat.

"The Coroner: What did you understand by that?

"Witness: It conveyed no meaning to me. I thought that he was
delirious.

"The Coroner: What was the point upon which you and your father
had this final quarrel?

"Witness: I should prefer not to answer.

"The Coroner: I am afraid that I must press it.

"Witness: It is really impossible for me to tell you. I can
assure you that it has nothing to do with the sad tragedy which
followed.

"The Coroner: That is for the court to decide. I need not point
out to you that your refusal to answer will prejudice your case
considerably in any future proceedings which may arise.

"Witness: I must still refuse.

"The Coroner: I understand that the cry of 'Cooee' was a common
signal between you and your father?

"Witness: It was.

"The Coroner: How was it, then, that he uttered it before he saw
you, and before he even knew that you had returned from Bristol?

"Witness (with considerable confusion): I do not know.

"A Juryman: Did you see nothing which aroused your suspicions
when you returned on hearing the cry and found your father
fatally injured?

"Witness: Nothing definite.

"The Coroner: What do you mean?

"Witness: I was so disturbed and excited as I rushed out into
the open, that I could think of nothing except of my father. Yet
I have a vague impression that as I ran forward something lay
upon the ground to the left of me. It seemed to me to be
something grey in colour, a coat of some sort, or a plaid perhaps.
When I rose from my father I looked round for it, but it was
gone.

"'Do you mean that it disappeared before you went for help?'

"'Yes, it was gone.'

"'You cannot say what it was?'

"'No, I had a feeling something was there.'

"'How far from the body?'

"'A dozen yards or so.'

"'And how far from the edge of the wood?'

"'About the same.'

"'Then if it was removed it was while you were within a dozen
yards of it?'

"'Yes, but with my back towards it.'

"This concluded the examination of the witness."

"I see," said I as I glanced down the column, "that the coroner
in his concluding remarks was rather severe upon young McCarthy.
He calls attention, and with reason, to the discrepancy about his
father having signalled to him before seeing him, also to his
refusal to give details of his conversation with his father, and
his singular account of his father's dying words. They are all,
as he remarks, very much against the son."

Holmes laughed softly to himself and stretched himself out upon
the cushioned seat. "Both you and the coroner have been at some
pains," said he, "to single out the very strongest points in the
young man's favour. Don't you see that you alternately give him
credit for having too much imagination and too little? Too
little, if he could not invent a cause of quarrel which would
give him the sympathy of the jury; too much, if he evolved from
his own inner consciousness anything so outr as a dying
reference to a rat, and the incident of the vanishing cloth. No,
sir, I shall approach this case from the point of view that what
this young man says is true, and we shall see whither that
hypothesis will lead us. And now here is my pocket Petrarch, and
not another word shall I say of this case until we are on the
scene of action. We lunch at Swindon, and I see that we shall be
there in twenty minutes."

It was nearly four o'clock when we at last, after passing through
the beautiful Stroud Valley, and over the broad gleaming Severn,
found ourselves at the pretty little country-town of Ross. A
lean, ferret-like man, furtive and sly-looking, was waiting for
us upon the platform. In spite of the light brown dustcoat and
leather-leggings which he wore in deference to his rustic
surroundings, I had no difficulty in recognising Lestrade, of
Scotland Yard. With him we drove to the Hereford Arms where a
room had already been engaged for us.

"I have ordered a carriage," said Lestrade as we sat over a cup
of tea. "I knew your energetic nature, and that you would not be
happy until you had been on the scene of the crime."

"It was very nice and complimentary of you," Holmes answered. "It
is entirely a question of barometric pressure."

Lestrade looked startled. "I do not quite follow," he said.

"How is the glass? Twenty-nine, I see. No wind, and not a cloud
in the sky. I have a caseful of cigarettes here which need
smoking, and the sofa is very much superior to the usual country
hotel abomination. I do not think that it is probable that I
shall use the carriage to-night."

Lestrade laughed indulgently. "You have, no doubt, already formed
your conclusions from the newspapers," he said. "The case is as
plain as a pikestaff, and the more one goes into it the plainer
it becomes. Still, of course, one can't refuse a lady, and such a
very positive one, too. She has heard of you, and would have your
opinion, though I repeatedly told her that there was nothing
which you could do which I had not already done. Why, bless my
soul! here is her carriage at the door."
"""

He had hardly spoken before there rushed into the room one of the
most lovely young women that I have ever seen in my life. Her
violet eyes shining, her lips parted, a pink flush upon her
cheeks, all thought of her natural reserve lost in her
overpowering excitement and concern.

"Oh, Mr. Sherlock Holmes!" she cried, glancing from one to the
other of us, and finally, with a woman's quick intuition,
fastening upon my companion, "I am so glad that you have come. I
have driven down to tell you so. I know that James didn't do it.
I know it, and I want you to start upon your work knowing it,
too. Never let yourself doubt upon that point. We have known each
other since we were little children, and I know his faults as no
one else does; but he is too tender-hearted to hurt a fly. Such a
charge is absurd to anyone who really knows him."

"I hope we may clear him, Miss Turner," said Sherlock Holmes.
"You may rely upon my doing all that I can."

"But you have read the evidence. You have formed some conclusion?
Do you not see some loophole, some flaw? Do you not yourself
think that he is innocent?"

"I think that it is very probable."

"There, now!" she cried, throwing back her head and looking
defiantly at Lestrade. "You hear! He gives me hopes."

Lestrade shrugged his shoulders. "I am afraid that my colleague
has been a little quick in forming his conclusions," he said.

"But he is right. Oh! I know that he is right. James never did
it. And about his quarrel with his father, I am sure that the
reason why he would not speak about it to the coroner was because
I was concerned in it."

"In what way?" asked Holmes.

"It is no time for me to hide anything. James and his father had
many disagreements about me. Mr. McCarthy was very anxious that
there should be a marriage between us. James and I have always
loved each other as brother and sister; but of course he is young
and has seen very little of life yet, and--and--well, he
naturally did not wish to do anything like that yet. So there
were quarrels, and this, I am sure, was one of them."

"And your father?" asked Holmes. "Was he in favour of such a
union?"

"No, he was averse to it also. No one but Mr. McCarthy was in
favour of it." A quick blush passed over her fresh young face as
Holmes shot one of his keen, questioning glances at her.

"Thank you for this information," said he. "May I see your father
if I call to-morrow?"

"I am afraid the doctor won't allow it."

"The doctor?"

"Yes, have you not heard? Poor father has never been strong for
years back, but this has broken him down completely. He has taken
to his bed, and Dr. Willows says that he is a wreck and that his
nervous system is shattered. Mr. McCarthy was the only man alive
who had known dad in the old days in Victoria."

"Ha! In Victoria! That is important."

"Yes, at the mines."

"Quite so; at the gold-mines, where, as I understand, Mr. Turner
made his money."

"Yes, certainly."

"Thank you, Miss Turner. You have been of material assistance to
me."

"You will tell me if you have any news to-morrow. No doubt you
will go to the prison to see James. Oh, if you do, Mr. Holmes, do
tell him that I know him to be innocent."

"I will, Miss Turner."

"I must go home now, for dad is very ill, and he misses me so if
I leave him. Good-bye, and God help you in your undertaking." She
hurried from the room as impulsively as she had entered, and we
heard the wheels of her carriage rattle off down the street.

"I am ashamed of you, Holmes," said Lestrade with dignity after a
few minutes' silence. "Why should you raise up hopes which you
are bound to disappoint? I am not over-tender of heart, but I
call it cruel."

"I think that I see my way to clearing James McCarthy," said
Holmes. "Have you an order to see him in prison?"

"Yes, but only for you and me."

"Then I shall reconsider my resolution about going out. We have
still time to take a train to Hereford and see him to-night?"

"Ample."

"Then let us do so. Watson, I fear that you will find it very
slow, but I shall only be away a couple of hours."

I walked down to the station with them, and then wandered through
the streets of the little town, finally returning to the hotel,
where I lay upon the sofa and tried to interest myself in a
yellow-backed novel. The puny plot of the story was so thin,
however, when compared to the deep mystery through which we were
groping, and I found my attention wander so continually from the
action to the fact, that I at last flung it across the room and
gave myself up entirely to a consideration of the events of the
day. Supposing that this unhappy young man's story were
absolutely true, then what hellish thing, what absolutely
unforeseen and extraordinary calamity could have occurred between
the time when he parted from his father, and the moment when,
drawn back by his screams, he rushed into the glade? It was
something terrible and deadly. What could it be? Might not the
nature of the injuries reveal something to my medical instincts?
I rang the bell and called for the weekly county paper, which
contained a verbatim account of the inquest. In the surgeon's
deposition it was stated that the posterior third of the left
parietal bone and the left half of the occipital bone had been
shattered by a heavy blow from a blunt weapon. I marked the spot
upon my own head. Clearly such a blow must have been struck from
behind. That was to some extent in favour of the accused, as when
seen quarrelling he was face to face with his father. Still, it
did not go for very much, for the older man might have turned his
back before the blow fell. Still, it might be worth while to call
Holmes' attention to it. Then there was the peculiar dying
reference to a rat. What could that mean? It could not be
delirium. A man dying from a sudden blow does not commonly become
delirious. No, it was more likely to be an attempt to explain how
he met his fate. But what could it indicate? I cudgelled my
brains to find some possible explanation. And then the incident
of the grey cloth seen by young McCarthy. If that were true the
murderer must have dropped some part of his dress, presumably his
overcoat, in his flight, and must have had the hardihood to
return and to carry it away at the instant when the son was
kneeling with his back turned not a dozen paces off. What a
tissue of mysteries and improbabilities the whole thing was! I
did not wonder at Lestrade's opinion, and yet I had so much faith
in Sherlock Holmes' insight that I could not lose hope as long
as every fresh fact seemed to strengthen his conviction of young
McCarthy's innocence.

It was late before Sherlock Holmes returned. He came back alone,
for Lestrade was staying in lodgings in the town.

"The glass still keeps very high," he remarked as he sat down.
"It is of importance that it should not rain before we are able
to go over the ground. On the other hand, a man should be at his
very best and keenest for such nice work as that, and I did not
wish to do it when fagged by a long journey. I have seen young
McCarthy."

"And what did you learn from him?"

"Nothing."

"Could he throw no light?"

"None at all. I was inclined to think at one time that he knew
who had done it and was screening him or her, but I am convinced
now that he is as puzzled as everyone else. He is not a very
quick-witted youth, though comely to look at and, I should think,
sound at heart."

"I cannot admire his taste," I remarked, "if it is indeed a fact
that he was averse to a marriage with so charming a young lady as
this Miss Turner."

"Ah, thereby hangs a rather painful tale. This fellow is madly,
insanely, in love with her, but some two years ago, when he was
only a lad, and before he really knew her, for she had been away
five years at a boarding-school, what does the idiot do but get
into the clutches of a barmaid in Bristol and marry her at a
registry office? No one knows a word of the matter, but you can
imagine how maddening it must be to him to be upbraided for not
doing what he would give his very eyes to do, but what he knows
to be absolutely impossible. It was sheer frenzy of this sort
which made him throw his hands up into the air when his father,
at their last interview, was goading him on to propose to Miss
Turner. On the other hand, he had no means of supporting himself,
and his father, who was by all accounts a very hard man, would
have thrown him over utterly had he known the truth. It was with
his barmaid wife that he had spent the last three days in
Bristol, and his father did not know where he was. Mark that
point. It is of importance. Good has come out of evil, however,
for the barmaid, finding from the papers that he is in serious
trouble and likely to be hanged, has thrown him over utterly and
has written to him to say that she has a husband already in the
Bermuda Dockyard, so that there is really no tie between them. I
think that that bit of news has consoled young McCarthy for all
that he has suffered."

"But if he is innocent, who has done it?"

"Ah! who? I would call your attention very particularly to two
points. One is that the murdered man had an appointment with
someone at the pool, and that the someone could not have been his
son, for his son was away, and he did not know when he would
return. The second is that the murdered man was heard to cry
'Cooee!' before he knew that his son had returned. Those are the
crucial points upon which the case depends. And now let us talk
about George Meredith, if you please, and we shall leave all
minor matters until to-morrow."

There was no rain, as Holmes had foretold, and the morning broke
bright and cloudless. At nine o'clock Lestrade called for us with
the carriage, and we set off for Hatherley Farm and the Boscombe
Pool.

"There is serious news this morning," Lestrade observed. "It is
said that Mr. Turner, of the Hall, is so ill that his life is
despaired of."

"An elderly man, I presume?" said Holmes.

"About sixty; but his constitution has been shattered by his life
abroad, and he has been in failing health for some time. This
business has had a very bad effect upon him. He was an old friend
of McCarthy's, and, I may add, a great benefactor to him, for I
have learned that he gave him Hatherley Farm rent free."

"Indeed! That is interesting," said Holmes.

"Oh, yes! In a hundred other ways he has helped him. Everybody
about here speaks of his kindness to him."

"Really! Does it not strike you as a little singular that this
McCarthy, who appears to have had little of his own, and to have
been under such obligations to Turner, should still talk of
marrying his son to Turner's daughter, who is, presumably,
heiress to the estate, and that in such a very cocksure manner,
as if it were merely a case of a proposal and all else would
follow? It is the more strange, since we know that Turner himself
was averse to the idea. The daughter told us as much. Do you not
deduce something from that?"

"We have got to the deductions and the inferences," said
Lestrade, winking at me. "I find it hard enough to tackle facts,
Holmes, without flying away after theories and fancies."

"You are right," said Holmes demurely; "you do find it very hard
to tackle the facts."

"Anyhow, I have grasped one fact which you seem to find it
difficult to get hold of," replied Lestrade with some warmth.

"And that is--"

"That McCarthy senior met his death from McCarthy junior and that
all theories to the contrary are the merest moonshine."

"Well, moonshine is a brighter thing than fog," said Holmes,
laughing. "But I am very much mistaken if this is not Hatherley
Farm upon the left."

"Yes, that is it." It was a widespread, comfortable-looking
building, two-storied, slate-roofed, with great yellow blotches
of lichen upon the grey walls. The drawn blinds and the smokeless
chimneys, however, gave it a stricken look, as though the weight
of this horror still lay heavy upon it. We called at the door,
when the maid, at Holmes' request, showed us the boots which her
master wore at the time of his death, and also a pair of the
son's, though not the pair which he had then had. Having measured
these very carefully from seven or eight different points, Holmes
desired to be led to the court-yard, from which we all followed
the winding track which led to Boscombe Pool.

Sherlock Holmes was transformed when he was hot upon such a scent
as this. Men who had only known the quiet thinker and logician of
Baker Street would have failed to recognise him. His face flushed
and darkened. His brows were drawn into two hard black lines,
while his eyes shone out from beneath them with a steely glitter.
His face was bent downward, his shoulders bowed, his lips
compressed, and the veins stood out like whipcord in his long,
sinewy neck. His nostrils seemed to dilate with a purely animal
lust for the chase, and his mind was so absolutely concentrated
upon the matter before him that a question or remark fell
unheeded upon his ears, or, at the most, only provoked a quick,
impatient snarl in reply. Swiftly and silently he made his way
along the track which ran through the meadows, and so by way of
the woods to the Boscombe Pool. It was damp, marshy ground, as is
all that district, and there were marks of many feet, both upon
the path and amid the short grass which bounded it on either
side. Sometimes Holmes would hurry on, sometimes stop dead, and
once he made quite a little detour into the meadow. Lestrade and
I walked behind him, the detective indifferent and contemptuous,
while I watched my friend with the interest which sprang from the
conviction that every one of his actions was directed towards a
definite end.

The Boscombe Pool, which is a little reed-girt sheet of water
some fifty yards across, is situated at the boundary between the
Hatherley Farm and the private park of the wealthy Mr. Turner.
Above the woods which lined it upon the farther side we could see
the red, jutting pinnacles which marked the site of the rich
landowner's dwelling. On the Hatherley side of the pool the woods
grew very thick, and there was a narrow belt of sodden grass
twenty paces across between the edge of the trees and the reeds
which lined the lake. Lestrade showed us the exact spot at which
the body had been found, and, indeed, so moist was the ground,
that I could plainly see the traces which had been left by the
fall of the stricken man. To Holmes, as I could see by his eager
face and peering eyes, very many other things were to be read
upon the trampled grass. He ran round, like a dog who is picking
up a scent, and then turned upon my companion.

"What did you go into the pool for?" he asked.

"I fished about with a rake. I thought there might be some weapon
or other trace. But how on earth--"

"Oh, tut, tut! I have no time! That left foot of yours with its
inward twist is all over the place. A mole could trace it, and
there it vanishes among the reeds. Oh, how simple it would all
have been had I been here before they came like a herd of buffalo
and wallowed all over it. Here is where the party with the
lodge-keeper came, and they have covered all tracks for six or
eight feet round the body. But here are three separate tracks of
the same feet." He drew out a lens and lay down upon his
waterproof to have a better view, talking all the time rather to
himself than to us. "These are young McCarthy's feet. Twice he
was walking, and once he ran swiftly, so that the soles are
deeply marked and the heels hardly visible. That bears out his
story. He ran when he saw his father on the ground. Then here are
the father's feet as he paced up and down. What is this, then? It
is the butt-end of the gun as the son stood listening. And this?
Ha, ha! What have we here? Tiptoes! tiptoes! Square, too, quite
unusual boots! They come, they go, they come again--of course
that was for the cloak. Now where did they come from?" He ran up
and down, sometimes losing, sometimes finding the track until we
were well within the edge of the wood and under the shadow of a
great beech, the largest tree in the neighbourhood. Holmes traced
his way to the farther side of this and lay down once more upon
his face with a little cry of satisfaction. For a long time he
remained there, turning over the leaves and dried sticks,
gathering up what seemed to me to be dust into an envelope and
examining with his lens not only the ground but even the bark of
the tree as far as he could reach. A jagged stone was lying among
the moss, and this also he carefully examined and retained. Then
he followed a pathway through the wood until he came to the
highroad, where all traces were lost.
"""

"It has been a case of considerable interest," he remarked,
returning to his natural manner. "I fancy that this grey house on
the right must be the lodge. I think that I will go in and have a
word with Moran, and perhaps write a little note. Having done
that, we may drive back to our luncheon. You may walk to the cab,
and I shall be with you presently."

It was about ten minutes before we regained our cab and drove
back into Ross, Holmes still carrying with him the stone which he
had picked up in the wood.

"This may interest you, Lestrade," he remarked, holding it out.
"The murder was done with it."

"I see no marks."

"There are none."

"How do you know, then?"

"The grass was growing under it. It had only lain there a few
days. There was no sign of a place whence it had been taken. It
corresponds with the injuries. There is no sign of any other
weapon."

"And the murderer?"

"Is a tall man, left-handed, limps with the right leg, wears
thick-soled shooting-boots and a grey cloak, smokes Indian
cigars, uses a cigar-holder, and carries a blunt pen-knife in his
pocket. There are several other indications, but these may be
enough to aid us in our search."

Lestrade laughed. "I am afraid that I am still a sceptic," he
said. "Theories are all very well, but we have to deal with a
hard-headed British jury."

"Nous verrons," answered Holmes calmly. "You work your own
method, and I shall work mine. I shall be busy this afternoon,
and shall probably return to London by the evening train."

"And leave your case unfinished?"

"No, finished."

"But the mystery?"

"It is solved."

"Who was the criminal, then?"

"The gentleman I describe."

"But who is he?"

"Surely it would not be difficult to find out. This is not such a
populous neighbourhood."

Lestrade shrugged his shoulders. "I am a practical man," he said,
"and I really cannot undertake to go about the country looking
for a left-handed gentleman with a game leg. I should become the
laughing-stock of Scotland Yard."

"All right," said Holmes quietly. "I have given you the chance.
Here are your lodgings. Good-bye. I shall drop you a line before
I leave."

Having left Lestrade at his rooms, we drove to our hotel, where
we found lunch upon the table. Holmes was silent and buried in
thought with a pained expression upon his face, as one who finds
himself in a perplexing position.

"Look here, Watson," he said when the cloth was cleared "just sit
down in this chair and let me preach to you for a little. I don't
know quite what to do, and I should value your advice. Light a
cigar and let me expound."

 "Pray do so."

"Well, now, in considering this case there are two points about
young McCarthy's narrative which struck us both instantly,
although they impressed me in his favour and you against him. One
was the fact that his father should, according to his account,
cry 'Cooee!' before seeing him. The other was his singular dying
reference to a rat. He mumbled several words, you understand, but
that was all that caught the son's ear. Now from this double
point our research must commence, and we will begin it by
presuming that what the lad says is absolutely true."

"What of this 'Cooee!' then?"

"Well, obviously it could not have been meant for the son. The
son, as far as he knew, was in Bristol. It was mere chance that
he was within earshot. The 'Cooee!' was meant to attract the
attention of whoever it was that he had the appointment with. But
'Cooee' is a distinctly Australian cry, and one which is used
between Australians. There is a strong presumption that the
person whom McCarthy expected to meet him at Boscombe Pool was
someone who had been in Australia."

"What of the rat, then?"

Sherlock Holmes took a folded paper from his pocket and flattened
it out on the table. "This is a map of the Colony of Victoria,"
he said. "I wired to Bristol for it last night." He put his hand
over part of the map. "What do you read?"

"ARAT," I read.

"And now?" He raised his hand.

"BALLARAT."

"Quite so. That was the word the man uttered, and of which his
son only caught the last two syllables. He was trying to utter
the name of his murderer. So and so, of Ballarat."

"It is wonderful!" I exclaimed.

"It is obvious. And now, you see, I had narrowed the field down
considerably. The possession of a grey garment was a third point
which, granting the son's statement to be correct, was a
certainty. We have come now out of mere vagueness to the definite
conception of an Australian from Ballarat with a grey cloak."

"Certainly."

"And one who was at home in the district, for the pool can only
be approached by the farm or by the estate, where strangers could
hardly wander."

"Quite so."

"Then comes our expedition of to-day. By an examination of the
ground I gained the trifling details which I gave to that
imbecile Lestrade, as to the personality of the criminal."

"But how did you gain them?"

"You know my method. It is founded upon the observation of
trifles."

"His height I know that you might roughly judge from the length
of his stride. His boots, too, might be told from their traces."

"Yes, they were peculiar boots."

"But his lameness?"

"The impression of his right foot was always less distinct than
his left. He put less weight upon it. Why? Because he limped--he
was lame."

"But his left-handedness."

"You were yourself struck by the nature of the injury as recorded
by the surgeon at the inquest. The blow was struck from
immediately behind, and yet was upon the left side. Now, how can
that be unless it were by a left-handed man? He had stood behind
that tree during the interview between the father and son. He had
even smoked there. I found the ash of a cigar, which my special
knowledge of tobacco ashes enables me to pronounce as an Indian
cigar. I have, as you know, devoted some attention to this, and
written a little monograph on the ashes of 140 different
varieties of pipe, cigar, and cigarette tobacco. Having found the
ash, I then looked round and discovered the stump among the moss
where he had tossed it. It was an Indian cigar, of the variety
which are rolled in Rotterdam."

"And the cigar-holder?"

"I could see that the end had not been in his mouth. Therefore he
used a holder. The tip had been cut off, not bitten off, but the
cut was not a clean one, so I deduced a blunt pen-knife."

"Holmes," I said, "you have drawn a net round this man from which
he cannot escape, and you have saved an innocent human life as
truly as if you had cut the cord which was hanging him. I see the
direction in which all this points. The culprit is--"

"Mr. John Turner," cried the hotel waiter, opening the door of
our sitting-room, and ushering in a visitor.

The man who entered was a strange and impressive figure. His
slow, limping step and bowed shoulders gave the appearance of
decrepitude, and yet his hard, deep-lined, craggy features, and
his enormous limbs showed that he was possessed of unusual
strength of body and of character. His tangled beard, grizzled
hair, and outstanding, drooping eyebrows combined to give an air
of dignity and power to his appearance, but his face was of an
ashen white, while his lips and the corners of his nostrils were
tinged with a shade of blue. It was clear to me at a glance that
he was in the grip of some deadly and chronic disease.

"Pray sit down on the sofa," said Holmes gently. "You had my
note?"

"Yes, the lodge-keeper brought it up. You said that you wished to
see me here to avoid scandal."

"I thought people would talk if I went to the Hall."

"And why did you wish to see me?" He looked across at my
companion with despair in his weary eyes, as though his question
was already answered.

"Yes," said Holmes, answering the look rather than the words. "It
is so. I know all about McCarthy."

The old man sank his face in his hands. "God help me!" he cried.
"But I would not have let the young man come to harm. I give you
my word that I would have spoken out if it went against him at
the Assizes."

"I am glad to hear you say so," said Holmes gravely.

"I would have spoken now had it not been for my dear girl. It
would break her heart--it will break her heart when she hears
that I am arrested."

"It may not come to that," said Holmes.

"What?"

"I am no official agent. I understand that it was your daughter
who required my presence here, and I am acting in her interests.
Young McCarthy must be got off, however."

"I am a dying man," said old Turner. "I have had diabetes for
years. My doctor says it is a question whether I shall live a
month. Yet I would rather die under my own roof than in a gaol."

Holmes rose and sat down at the table with his pen in his hand
and a bundle of paper before him. "Just tell us the truth," he
said. "I shall jot down the facts. You will sign it, and Watson
here can witness it. Then I could produce your confession at the
last extremity to save young McCarthy. I promise you that I shall
not use it unless it is absolutely needed."

"It's as well," said the old man; "it's a question whether I
shall live to the Assizes, so it matters little to me, but I
should wish to spare Alice the shock. And now I will make the
thing clear to you; it has been a long time in the acting, but
will not take me long to tell.

"You didn't know this dead man, McCarthy. He was a devil
incarnate. I tell you that. God keep you out of the clutches of
such a man as he. His grip has been upon me these twenty years,
and he has blasted my life. I'll tell you first how I came to be
in his power.

"It was in the early '60's at the diggings. I was a young chap
then, hot-blooded and reckless, ready to turn my hand at
anything; I got among bad companions, took to drink, had no luck
with my claim, took to the bush, and in a word became what you
would call over here a highway robber. There were six of us, and
we had a wild, free life of it, sticking up a station from time
to time, or stopping the wagons on the road to the diggings.
Black Jack of Ballarat was the name I went under, and our party
is still remembered in the colony as the Ballarat Gang.

"One day a gold convoy came down from Ballarat to Melbourne, and
we lay in wait for it and attacked it. There were six troopers
and six of us, so it was a close thing, but we emptied four of
their saddles at the first volley. Three of our boys were killed,
however, before we got the swag. I put my pistol to the head of
the wagon-driver, who was this very man McCarthy. I wish to the
Lord that I had shot him then, but I spared him, though I saw his
wicked little eyes fixed on my face, as though to remember every
feature. We got away with the gold, became wealthy men, and made
our way over to England without being suspected. There I parted
from my old pals and determined to settle down to a quiet and
respectable life. I bought this estate, which chanced to be in
the market, and I set myself to do a little good with my money,
to make up for the way in which I had earned it. I married, too,
and though my wife died young she left me my dear little Alice.
Even when she was just a baby her wee hand seemed to lead me down
the right path as nothing else had ever done. In a word, I turned
over a new leaf and did my best to make up for the past. All was
going well when McCarthy laid his grip upon me.

"I had gone up to town about an investment, and I met him in
Regent Street with hardly a coat to his back or a boot to his
foot.

"'Here we are, Jack,' says he, touching me on the arm; 'we'll be
as good as a family to you. There's two of us, me and my son, and
you can have the keeping of us. If you don't--it's a fine,
law-abiding country is England, and there's always a policeman
within hail.'

"Well, down they came to the west country, there was no shaking
them off, and there they have lived rent free on my best land
ever since. There was no rest for me, no peace, no forgetfulness;
turn where I would, there was his cunning, grinning face at my
elbow. It grew worse as Alice grew up, for he soon saw I was more
afraid of her knowing my past than of the police. Whatever he
wanted he must have, and whatever it was I gave him without
question, land, money, houses, until at last he asked a thing
which I could not give. He asked for Alice.

"His son, you see, had grown up, and so had my girl, and as I was
known to be in weak health, it seemed a fine stroke to him that
his lad should step into the whole property. But there I was
firm. I would not have his cursed stock mixed with mine; not that
I had any dislike to the lad, but his blood was in him, and that
was enough. I stood firm. McCarthy threatened. I braved him to do
his worst. We were to meet at the pool midway between our houses
to talk it over.

"When I went down there I found him talking with his son, so I
smoked a cigar and waited behind a tree until he should be alone.
But as I listened to his talk all that was black and bitter in
me seemed to come uppermost. He was urging his son to marry my
daughter with as little regard for what she might think as if she
were a slut from off the streets. It drove me mad to think that I
and all that I held most dear should be in the power of such a
man as this. Could I not snap the bond? I was already a dying and
a desperate man. Though clear of mind and fairly strong of limb,
I knew that my own fate was sealed. But my memory and my girl!
Both could be saved if I could but silence that foul tongue. I
did it, Mr. Holmes. I would do it again. Deeply as I have sinned,
I have led a life of martyrdom to atone for it. But that my girl
should be entangled in the same meshes which held me was more
than I could suffer. I struck him down with no more compunction
than if he had been some foul and venomous beast. His cry brought
back his son; but I had gained the cover of the wood, though I
was forced to go back to fetch the cloak which I had dropped in
my flight. That is the true story, gentlemen, of all that
occurred."

"Well, it is not for me to judge you," said Holmes as the old man
signed the statement which had been drawn out. "I pray that we
may never be exposed to such a temptation."

"I pray not, sir. And what do you intend to do?"

"In view of your health, nothing. You are yourself aware that you
will soon have to answer for your deed at a higher court than the
Assizes. I will keep your confession, and if McCarthy is
condemned I shall be forced to use it. If not, it shall never be
seen by mortal eye; and your secret, whether you be alive or
dead, shall be safe with us."

"Farewell, then," said the old man solemnly. "Your own deathbeds,
when they come, will be the easier for the thought of the peace
which you have given to mine." Tottering and shaking in all his
giant frame, he stumbled slowly from the room.

"God help us!" said Holmes after a long silence. "Why does fate
play such tricks with poor, helpless worms? I never hear of such
a case as this that I do not think of Baxter's words, and say,
'There, but for the grace of God, goes Sherlock Holmes.'"

James McCarthy was acquitted at the Assizes on the strength of a
number of objections which had been drawn out by Holmes and
submitted to the defending counsel. Old Turner lived for seven
months after our interview, but he is now dead; and there is
every prospect that the son and daughter may come to live happily
together in ignorance of the black cloud which rests upon their
past.
