Jack the Ripper was not the only serial killer roaming the streets of London in 1888. Between 1887 and 1889, at least three women were killed and dismembered, and parts of their bodies disposed of in the Thames, although in one case, the torso and other parts were discovered on the grounds of the construction site for the new Scotland Yard building. The identity of the Thames Torso killer has never been determined, and there is some question as to whether the three murders he is agreed to have committed are the full extent of his crimes, as similar cases, also unsolved, had occurred in 1873-4 and 1884.
In Mayhem, Sarah Pinbourough infuses the facts of the Thames Torso Murders with a markedly supernatural story of possession by an ancient spirit of evil. The novel is centred on police surgeon Thomas Bond, who was an early practitioner of the science of forensic profiling, having produced a profile of the Ripper. Bond did play a historical role in the investigation of both the Ripper and the Thames Torso killer, performing autopsies on both Mary Jane Kelly and the second of the Torso killer's victims, Elizabeth Jackson. The novel gives him a much greater role, however, in the detection and final resolution of the murders.
I thoroughly enjoyed Pinborough's genre-bending historical crime horror novel on all counts.
