What makes a serial killer? Only one man really knows. FBI Special Agent and expert in criminal profiling and behavioural science, John Douglas. A man who has looked evil in the eye and made a vocation of understanding it. Now retired, Douglas can let us inside the FBI elite serial crime unit and into the disturbed minds of some of the most savage serial killers in the world. The man who was the inspiration for Special Agent Jack Crawford in The Silence of the Lambs and who lent the film's makers his expertise explains how he invented and established the practice of criminal profiling; what it was like to submerge himself mentally in the world of serial killers to the point of 'becoming' both perpetrator and victim; and individual case histories including those of Jeffrey Dahmer, Charles Manson, Ted Bundy and the Atlanta child murders. With the fierce page-turning power of a bestselling novel, yet terrifyingly true, Mindhunter is a true crime classic.
