In this fascinating, in-depth account of the hunt for serial killers, Colin Wilson, one of the world's leading authorities on the subject, examines the ways they can be tracked down and caught, from the tried-and-true methods of the early 20th century to the high-tech processes in use today. Wilson examines such areas as psychological profiling, genetic fingerprinting, and the launch of the Behavioural Science Unit. He delves into the importance of fantasy to serial killers, the urge to keep on killing, the desire to become notorious, and murder as an addictive drug. He includes his own correspondence with serial killers and follows the career of FBI Special Agent Robert Ressler, the man who coined the term 'serial killer' in 1977. Including the worst murderers in Britain and America such as Peter Sutcliffe, Fred and Rosemary West, Jeffrey Dahmer and Paul Bernardo, this book is an essential read for true crime enthusiasts. It is for all of us morbidly fascinated by these gruesome murders but especially by the techniques used to bring those responsible to justice.
