Against advice from her niece Lucy, Kay Scarpetta answers a request to return to the Richmond medical examiner's office, the same office from which she was fired, to help with the sensitive case of a dead teen. When she and Pete Marino arrive, they find the new medical examiner to be a vituperative, uncooperative martinet and the office that Kay ran so efficiently in chaos. Two murders, oddly linked, demand their attention. In the meantime, Lucy, still unsettled despite her success with the Last Precinct investigative agency, is having personal problems (there's been an attack on her housemate), which strangely enough find her treading the same path as her aunt Kay. Traces of the smart, dynamic, yet vulnerable Scarpetta of the early novels are in evidence here, and Cornwell has better control of her plot and characters than in her last few efforts, faltering only occasionally when psychobabble weighs things down. The mystery is intriguing, there's plenty of forensic detail, and the ending, though perhaps too abrupt, opens the way for Scarpetta and her associates to proceed in any direction that calls to them.
