Professional grave robber and semi-professional loon, Simon Diggery, won't let Stephanie Plum take him in until she agrees to care for his boa constrictor, Ethel. Then headless bodies start appearing across town. When a homeless man is murdered and dumped behind a church Stephanie knows that she's the only one with a prayer of catching this killer. If all that's not enough, Diesel's back in town. Cop Joe Morelli isn't pleased at this unexpected arrival nor is Ranger, the high-powered security consultant who has his own plans for Stephanie.
