Virginia's chief medical examiner, Kay Scarpetta, is called in to examine the remains of a woman found in a landfill, her body dismembered in the same expert way she'd seen before. And while Scarpetta is investigating, the bold killer contacts her through the Internet, inviting her to download the police photos, and signs off with the chilling name, deadoc. When Scarpetta and her niece discover that the victim was exposed to a rare smallpox-like virus before she died, she realizes that they re up against a killer with access to an incredible arsenal of deadly force -- and now it's directed at her!
