John Douglas is a former FBI Special Agent and expert in criminal profiling and behavioural science. He made a career of looking evil in the eye - and understanding it. No wonder that he was the inspiration for Special Agent Jack Crawford in The Silenceof the Lambs, as well as the film's consultant on the reality of serial killers.Douglas invented and established the practice of criminal profiling, and submerged himself in the world of serial killers in a quest to understand why they killed, and tohelp prevent more innocent lives from being ended by future killers. As his serial crime unit developed from a derided two-bit operation in a dingy officer to one of the FBI's elite task forces, Douglas personally confronted the most terrible crimes ofthe age, including those of Jeffrey Dahmer, Charles Manson, Ted Bundy and the Atlanta child murderer.
