Revelatory investigation into the police handling of the Yorkshire Ripper Case which spanned over 14 years. For the first time, the files have been opened, the detectives are talking and the victims are reliving the nightmare. For over twenty 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 manhours 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. Award-winning writer Michael Bilton has persuaded the key people to talk. After years of exhaustive research he can finally reveal the extraordinary 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 reads as tensely as any thriller. Its measured analysis of the calamitous investigation is also a shocking and important indictment of the most notorious murder hunt of the twentieth century.
