‘It was a suicide mission,’ the Rememberer said. ‘A volunteer allowed her body to be pumped full of Squeem-specific toxins and pathogens. Harry wasn’t the assassin, and nor was he educated enough to have manufactured the toxins. Underground cells of fifty-somethings, the last generation of pre-invasion scientists, laboured over that. But Harry was a link in the chain that got the toxins to the assassin, and he helped provide a diversion that enabled the woman to finish the job.’
The woman just jumped into Lake Superior, one bright morning, her body weighted with bags of rocks. She slit her own wrists and let her crimson blood spill into the waters.
‘Every Lethe-spawned Squeem in that lake died,’ Karl Hume said. ‘They felt that loss all the way back to their homeworld. And I mean it, those group-minded bastards all felt it.’
