This is a fascinating, intelligent, and engaging look into the world of the criminal profiler. Drawing on recent studies by the FBI Behavioural Science Unit and interviews with leading investigators, most of them pioneers in the development of the profiling process, his fascinating volume takes readers into the eerie world of the criminal profiling process. The first section focuses on the seminal David Meirhofer case, a land-mark moment for the Behavioural Science Unit and one of the first mysteries solved by criminal profiling. Section two examines the use and value of psycholinguistics, criminal "signature" left at crime scenes, predatory tactics, and interviews with violent offenders. The final section considers factors affecting police investigations, detecting clues, and investigative failures.
