Virginia Chief Medical Examiner Kay Scarpetta is called in to autopsy the body of convicted murderer Ronnie Waddell after his execution. Several days after the execution, a young boy is discovered murdered in the fashion of Waddell's earlier killings, with Waddell's prints near the body. Scarpetta, along with FBI Agent Benton Wesley and Detective Pete Marino, try to discover how a dead inmate could have possibly committed another murder after his death. As the story progresses she seeks the assistance of her 17-year-old niece Lucy after she discovers a strange folder on her computer.
Nicholas Grueman – Lawyer, advocate for the abolition of capital punishment, deeming it "cruel and unusual." Also Scarpetta's Georgetown lecturer, who had always seemed to be hard onKay but it turned out that he had her interests at heart while doing so.
Ben Stevens – Kay's morgue administrator. Is into drugs and a party-lifestyle. Being bribed by Frank Donahue to tamper with evidence.
Temple Brooks Gault – The killer of the victims in the book. Uses the alias Hilton Sullivan. Being described by Benton Wesley as being "off the charts. If something strikes his fancy, he just does it. He's consummately narcissistic and vain – his hair, for example. He highlights it himself." He escaped apprehension.
Victims
Eddie Heath – 13-year-old boy who was murdered in a manner similar to Robyn Naismith years before. He had a single gunshot wound to his head, which he did not immediately die of. He was found naked with his back propped against a dumpster in a back alley. It was alleged he was abducted and killed while he was on the way home from a grocery shop.
Jennifer Deighton – When discovered in the car, originally thought to be a suicide. A hose was hooked up to the exhaust pipe. However, during the postmortem autopsy, her cause of death was asphyxiation.
Susan Dawson Story – Kay's morgue supervisor. Was being bribed by Ben Stevens. Did so because of personal financial trouble.
Frank Donahue – Prison warden where Ronnie Joe Waddell is interned. He released an inmate, because he "needed some dirty work done. So he selected an inmate to be his personal operative and set the animal loose."
