In London, with Jack the Ripper's crimes still raw in the great city's memory, a well-known male prostitute is brutally murdered, the head neatly severed, and the body set on fire. Detective Inspector Phillip Devlin of Scotland Yard, mid-thirties and secretly gay, is called to the murder scene by plainclothes constable Freddie Collins, and soon both Collins and Devlin are caught in a web of intrigue as more savage murders occur. A Cold-Blooded Scoundrel resonates with the sights, sounds, and atmosphere of 1880s London.
