Pinkerton detective Sebastian Becker bumps into an old adversary, the down and out former boxing champion Tom Sayers who was once framed for the horrific murders of English street children but escaped. Sayers, at the time road manager for a theater company, had become obsessed with the lovely Louise Porter, and his obsession takes him from England to America as he follows her trail. As the story switches between present day (1860's) America and London's theatrical underbelly while the besotted Sayers searches for Louise, the tale takes on unexpected demonic dimensions. Fans of the occult will enjoy this, as will lovers of the historic mystery genre. A 5.
