Set in a fictional version of London, with advanced medical technology. The game centers on a private detective named Arthur Hewitt, whose office lies in a small corner of London. During an investigation of serial murders, Arthur's resolve is shaken, and he begins to see visions of a man who identifies himself to Arthur as Jack the Ripper. The real Jack the Ripper, a serial killer himself, was apprehended and executed two years ago. Driven to the brink by the visions, Arthur is embroiled in one ghastly incident after another on the streets of London.
