When Jack the Ripper terrorised London in 1888, he would spark a mystery when he disappeared and his string of violent and horrific murders ended as quickly as they began, leaving one of the worlds oldest unsolved crimes in his wake. Now, in 1907, biographer Charles Hapgood is about to be visited a man with astonishing claims that he was the famous Ripper and wishes to tell his tale before his coming death. Sceptical at first, Hapgood agrees to hear his story, only to soon be shown undisputable proof that his visitor speaks the truth and is who he claims to be. As Hapgood listens to the man's tale, he is drawn into a world of pain, cruelty, horror and sadness as he discovers how an innocent child grew into the greatest living monster the world has ever seen. As the story unfolds he begins to fear for his own safety as the man once known as Jack The Ripper tells his story in his own words, a tale which goes far beyond the known timeline of his horrific crimes and reaches new depths of terror and depravity that Hapgood could never have imagined.
