In the tomblike silence of an abandoned rock quarry, someone is trying to hide their dirty little secret. A secret that reveals the depths of human depravity. A secret that is about to be discovered. When FBI Special Agent Maggie O'Dell receives a call from Sheriff Henry Watermeier of New Haven County, Connecticut, she assumes it's a routine tip. She's working on the case of a missing D.C.-area woman, and it seems her body had been found. But Maggie's about to learn this is just the tip of the iceberg in what will be one of the most bizarre, cold-blooded and confounding cases of her career a a criminal profiler. During a cleanup excavation in the deserted quarry, a fifty-five-gallon drum was discovered, containing the remains of a woman. Then more barrels are found, containing more bodies: some of the dead have been brutally murdered, and some have already been buried.
