VTK... For more than 30 years, a man under this pseudonym kept the whole city in fear. He suddenly appeared and just as suddenly disappeared, simultaneously playing cat and mouse with the police, sending them mocking narcissistic messages. Fortunately, it was this quality that ruined him. John Douglas is one of the first forensic profilers who has been involved in this case from the very beginning. In his books, the author shares information about how the brain and consciousness of murderers are arranged in order to dispel the myths around them and enable readers to protect themselves and others from the possible appearance of new violent criminals.In this book you will find:- the history of the investigation of BTK crimes;- the subtleties and nuances of the trial of a maniac;- exclusive interview with BTK.
