Plot summary

Dr Kay Scarpetta, Virginia Chief Medical Examiner and consulting pathologist for the federal law enforcement agency ATF, is called out to a farmhouse in Virginia that has been destroyed by fire. In the ruins of the house she finds a body that tells a story of a violent and grisly murder.

The fire has come at the same time as Carrie Grethen, a killer who nearly destroyed the lives of Scarpetta and those closest to her, has escaped from a forensic psychiatric hospital. Her whereabouts is unknown, but her ultimate destination is not, for Carrie has begun to communicate with Scarpetta, conveying her deadly—if cryptic—plans for revenge.

Carrie has linked up with a new companion, willing to end his life of sadistic slayings for her pursuit of Scarpetta.

Found dead in the master bedroom bath at Kenneth Sparks's house in Warrenton, body burnt, with a glass door on top of her. Her arms had disintegrated due to the intense heat of the fire. There was hemorrhaging at her neck, and blood in her airway, which is uncharacteristic for a death due to fire. She also had no traces of carbon in her oesophagus, which led Kay to believe her death was a homicide. Fire started in the master bathroom.
Kellie Shephard – Thirty-two-year-old black female who worked as a nurse in Lehigh County, Pennsylvania.

Benton Wesley – Found in a grocery shop downtown. Face charred beyond recognition, but was identified by Kay from the Breitling watch she gave him. Hands and ankles were burnt to the point of detachment, and handcuffs were found nearby, double locked, suggesting he was probably cuffed and burnt to death.

They were placed on mannequin heads, wrapped up in layers of plastic, and stored in his refrigerator. He also aided in Carrie Grethen's escape by means of his personal helicopter. For reasons unclear he decides to help Carrie in her plan against Scarpetta, and willingly exposes his history of murders ending in a suicidal attack, along with Carrie, on Scarpetta and her niece in which his helicopter crashes killing them both.
