This is the remarkable inside story of the biggest and most controversial hoax in criminal history. In the late 1970’s a series of letters and a tape were sent to detectives trying to catch serial killer Peter Sutcliffe – The Yorkshire Ripper. The police were led on a two-year-long chase for the wrong man, allowing Sutcliffe to murder three more women. Finally found guilty 25 years after leading the hoax, this is the story of John Humble.
