The police handling of the Yorkshire Ripper case, which spanned over 14 years, is investigated in this book. For the first time, the files have been opened, the detectives are talking and the victims are reliving the nightmare. For over 20 years, the dark secrets of the biggest criminal manhunt in British history have remained a closed book. Detectives refused all requests to tell the inside story of the Yorkshire Ripper investigation that logged over two million man-hours of police work. The victims who survived maintained a wall of silence. And the detailed forensic evidence, witness statements and autopsy reports have remained locked away. Until now. Michael Bilton has persuaded the key people to talk. After years of research he can finally reveal the truth behind the murder enquiry that left Peter Sutcliffe free to kill again and again. With exclusive access to the detectives involved, to pathologist's archives and confidential police reports, the story of the hunt is revealed.
