Working as an enforcer in London's criminal underworld brought Dan Shaper to the edge of a breakdown. Now he's a private investigator, kept perilously afloat by a growing cocktail of drugs. He needs to straighten up and rebuild his life, but instead he gets the attention of his old gangland masters and a job offer from Mr. George Glass. The elderly eccentric claims to be a New Age Messiah, but now needs a savior of his own: he's been marked for murder. Adrift amidst liars and thugs, Shaper must push his capsizing mind to its limits, as he is stalked not only by a unique and terrifying killer, but by the ghosts of his own brutal past.
