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. It dispels a lot of myths attached to the Ripper, and eliminates a lot of the previously conjectured perpetrators, leaving only those who realistically could have been...Jack the Ripper.
