A Philosophical Investigation

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 posi­tive 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.
