Dr. Azor Moses Sparks is an extremely esteemed heart surgeon, a devout fundamentalist Christian, a cyclist, a friend of biker gangs; a friend to all. Until he is found dead in an alley with his chest ripped open, that is. Where does one go to begin in the investigation of a man who had no enemies? Lt. Peter Decker starts with the man's family, which he discovers is large and filled with strife and unstable characters. He also finds some problems in his own affairs, mostly involving religious beliefs--his own, those of his Orthodox Jewish wife and those of a Roman Catholic priest who plays a prominent role in the multilayered thriller.
