Mayhem is a masterwork of narrative suspense: a supernatural thriller set in a shadowy, gaslit London, where monsters stalk the cobbled streets and hide in plain sight.

A new killer is stalking the streets of London’s East End. Though newspapers have dubbed him "the Torso Killer", this murderer’s work is overshadowed by the hysteria surrounding Jack the Ripper’s Whitechapel crimes.

The victims are women too, but their dismembered bodies, wrapped in rags and tied up with string, are pulled out of the Thames--and the heads are missing. The murderer likes to keep them.
