"It is mankind's most abominable crime: murder. No one is better acquainted with the subject and its wrenching challenges than John Douglas, the FBI's pioneer of criminal profiling, and the model for Agent Jack Crawford in 'The Silence of the Lambs.' In this provocative and deeply personal book, the most prominent criminal investigator of our time offers a rare look ino the workings not only of the justice system--but of his own heart and mind. Writing with award-winning partner Mark Olshaker, Douglas opens up about his most notorious and baffling cases--and shows what it's like to confront evil in its most monstrous form."--Back cover.
