Crime Series #7

 Cause of Death by Patricia Cornwell 

This was another good installment in this crime series. Scarpetta is called to a body in the water; a reporter died while scuba diving. the cops on scene think it was accidental. It wasn't. She starts getting harassed by a young, attractive cop who ends up filing a sexual harassment claim against her. This is all tied in with a cult. The young cop was part of the cult and was their inside informant as was the NIS agent on the case. The cult takes over a nuclear power plant and they have no way to get in. Lucy is working on a robot that is used to get in. Eventually, we discover that the dead reporters girlfriend was also involved with the cult and was playing both sides. When the leader of the cult falls into the radioactive water Kay goes into the power plant to "save" him even though she knows he's going to die; she's just stalling for time. She manages to stall long enough that she needs more supplies and convinces the other cult members to use the robot to bring in the supplies. That gives the FBI time to breach and save Kay and the hostages. The mystery is good, but the science of it all is the most interesting part.
