Critically acclaimed, bestselling author Michael Gruber's second novel to feature police detective Jimmy Paz is a chilling and remarkable work of intelligence and imagination. After a wealthy oilman plunges ten stories to his death from the balcony of a Miami hotel, Paz and the young cop who witnessed the fall discover a woman on her knees praying in the dead man's room. A motive and strong evidence point to the woman—Emmylou Dideroff—as the murderer, but she insists that she's innocent of the crime, while freely admitting her guilt in numerous other criminal acts and abominations. As her shocking confessions blur the lines between charity and vengeance, delusion and reality, Paz finds himself drawn once again into the unexplained . . . and into a collision with an evil of inconceivable power.
