A terrifyingly prescient cult classic by the bestselling author of the Bernie Gunther series.

Chilling…absorbing…part techno-thriller, part futuristic detective story, part diary of a serial killer. -The New York Times Book Review

LONDON, 2013. Serial killings have reached epidemic proportions-even with the widespread government use of DNA detection, brain-imaging, and the punitive coma. Beautiful, whip-smart, and driven by demons of her own, Detective Isadora Jake Jacowicz must stop a murderer, code-named Wittgenstein, who has taken it upon himself to eliminate any man who has tested posi tive for a tendency towards violent behavior-even if his victim has never committed a crime. He is a killer whose intellectual brilliance is matched only by his homicidal madness.
