A Philosophical Investigation
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.
