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 destroyed him. John Douglas is one of the original forensic profilers and has been involved with this case from the very beginning. In his books, the author shares information about how the brain and consciousness of murderers work in order to dispel the myths around them and enable readers to protect themselves and others from the possible emergence of new brutal criminals. In this book you will find: • the history of the investigation of BTK crimes; • subtleties and the nuances of the trial of a maniac;• exclusive interview with BTK.
