This work delves deep into the case of the Thames Torso Murders. It begins with a look at London in the late 1800s, a time of great confusion and tremendous population increase, and the killer's path to London, which seems to include a murder in Paris in 1886. The book then examines in great detail each murder and the investigation that may have been hindered by the search for Jack the Ripper. It also raises the idea that Jack the Ripper and the Torso Murderer may have been the same man--Severin Klosowski, better known as George Chapman, the Borough Poisoner. It ends with an examination of Serial Killers; the Ripper, Torso, and Borough Poisoner murder cases; the search for clues to the serial killer responsible for the five Thames Torso murders; and Wolff Levisohn, a dark horse who seems to have known much about all three sets of murders, testified at Chapman's murder trial, and then faded away as Chapman was sent to the gallows.
