The sky above the port was the color of television, tuned        \n\
to a dead channel.                                               \n\
                                                                 \n\
  `It's not like I'm using,' Case heard someone say, as he       \n\
shouldered his way through the crowd around the door of the      \n\
Chat.  `It's like my body's developed this massive drug defi-    \n\
ciency.'  It was a Sprawl voice and a Sprawl joke.  The Chatsubo \n\
was a bar for professional expatriates; you could drink there    \n\
for a week and never hear two words in Japanese.                 \n\
                                                                 \n\
  Ratz was tending bar, his prosthetic arm jerking monoto-       \n\
nously as he filled a tray of glasses with draft Kirin.  He saw  \n\
Case and smiled, his teeth a webwork of East European steel      \n\
and brown decay.  Case found a place at the bar, between the     \n\
unlikely tan on one of Lonny Zone's whores and the crisp naval   \n\
uniform of a tall African whose cheekbones were ridged with      \n\
precise rows of tribal scars.  `Wage was in here early, with two \n\
joeboys,' Ratz said, shoving a draft across the bar with his     \n\
good hand.  `Maybe some business with you, Case?'                \n\
