Postmortem
Patricia Cornwell
 The novel opens as Dr. Kay Scarpetta, Chief Medical Examiner for the state of Virginia, receives an early-morning call from Sergeant Pete Marino, a homicide detective at the Richmond Police Department with whom Scarpetta has a tense working relationship. She meets him at the scene of a woman's gruesome strangling, the latest in a string of unsolved murders in Richmond. The killer leaves behind few clues; among them are a mysterious substance which fluoresces under laser light, traces of semen, and in the vicinity of the last murder, an unusual smell. Scarpetta and Marino work with FBI profiler Benton Wesley to attempt to piece together a profile of the killer. Initial evidence appears to point to the fourth victim's husband, but Scarpetta suspects otherwise despite Marino's insistence. (The book references DNA profiling as a relatively new technique, and characters briefly bemoan the lack of a criminal DNA database which could provide better leads to suspects, given available evidence.) Meanwhile in her personal life, Scarpetta must deal with the presence of her extremely precocious ten-year-old niece, Lucy, as well as an uncertain romantic relationship with the local Commonwealth's attorney. During the investigation, a series of news leaks about the murders appear to be coming from a source within the medical examiner's office. The leaks threaten Scarpetta's position, especially after she is forced to admit that her office database has been compromised. Believing that the killer thrives on media attention and hoping to flush him out by provoking his ego, Scarpetta, Wesley, and local investigative reporter Abby Turnbull (whose sister was the fifth victim) conspire to release a news story which suggests that the killer has a distinctive body odor due to a rare metabolic disease and implies that the killer may be mentally disordered. While attempting to find another link between the five murders, Scarpetta discovers that all five intended victims had recently called 911; she suspects that the killer is a 911 operator and chose his victims based on their voices. Scarpetta is awakened in the middle of the night by the killer, who has broken into her home. As she attempts to reach a gun she has kept nearby for protection, Marino bursts into her bedroom and shoots the intruder, having realized that the news article would make Scarpetta a likely target. Scarpetta's suspicion proves to be correct; the killer was a police and sometime 911 dispatcher.
