It's the second-to-last day of archaeological field school - the students are working on a site of prehistoric graves on Dewees, a barrier island north of Charleston, South Carolina, when a much more recent burial is uncovered. It's a case forensic anthropologist Temperance Brennan has to take. But, it seems to be putting herself in danger.
When a careless plumber accidentally knocks through a wall, he is horrified by what he uncovers. Called to the scene is forensic anthropologist Dr Temperance Brennan. What awaits her is a ritualistic display. Must Tempe face the sickening possibility that Devil-worshippers are sacrificing human victims?
A routine case turns sinister when Dr Temperance Brennan is accused of mishandling the autopsy of a missing heiress. Someone has made an incriminating accusation that she missed or concealed crucial evidence. Before Tempe can get to the one man with information, he turns up dead.
