Over a century ago, a depraved killer skillfully moved through the dark and filthy slums of London's East End. Despite the increasingly watchful eyes of investigators, the serial murderer--known as -Jack the Ripper- from a signature on a piece of correspondence that has been attributed to him--was never certainly identified. R. Michael Gordon provides a comprehensive look at the crimes and the case evidence, and then discusses the life of the man he believes was the actual killer, detailing the reasons why this person may have been driven to kill. Beginning with an overview of the terror created in the East End of 1888, the book describes the five major periods of the Ripper's deadly career: early life and schooling; a step-by-step view of the murders, including the Thames Torso Murders that authorities attempted to cover up; the Ripper's American connection; a return to London where his final victims were subjected to poison; and the capture and execution of the probable--but never proven--Ripper. To most people who worked closely on the Ripper and poisoning cases, justice was finally served.
