Crimes, Detection and Death of Jack the Ripper by Martin Fido
 
This book re-examines all the sensational details of the murders ascribed to Jack the Ripper. It investigates the roles and reliability of the policemen involved in the murder inquiry and analyzes the evidence against all the suspects--checking them against the personality patterns of other sexual serial murderers. The author, whose conclusion was endorsed by the Scotland Yard & the F.B.I., provides a convincing identification of the Ripper.
