A Philosophical Investigation: A Novel [Paperback]

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.Praise forA Philosophical Investigation
