Unnatural Exposure
Patricia Cornwell
 Virginia Chief Medical Examiner Kay Scarpetta has a bloody puzzle on her hands: five headless, limbless cadavers in Ireland, plus four similar victims in a landfill back home. Is a serial butcher loose in Virginia? That's what the panicked public thinks, thanks to a local TV reporter who got the leaked news from Scarpetta's rival, Investigator Percy Ring. But this is no run-of-the-mill serial killer. A shadowy figure has plans involving mutant smallpox, mass murder, and messing with Scarpetta's mind by e-mailing her gory photos of the murder scenes, along with cryptic AOL chat-room messages. Central to the plot is the case of Janet Parker, the last person known to have died of smallpox, which she contracted in 1978 due to a lab accident in Birmingham, England, after the disease was eradicated in the wild. Cornwell makes the villain a junior employee of the lab at the time who was made a scapegoat for the accident and whose career was blighted as a result. This provides the plot with a credible source for the virus and a motive for the central crime.
