Horrific, horrendous, unspeakable, The Whitechapel Murderer, Jack the Ripper, stalked the streets of East London in 1888, slaughtering prostitutes and bewildering the police who were hunting him. They never succeeded in apprehending him, and to this day the mystery of his identity remains an enigma. But he did leave clues to his identity, and numerous theories have been entertained throughout the one hundred and twenty years since he held London s East End in his grip of terror. This book looks at the evidence left by the murderer and the reports and investigative papers which recorded the atrocities that the ripper performed. It takes time to analyse the existing information and evaluate the letters sent to the police. It is the strongest and most powerful book ever written on the murders.
