Identity Unknown

Summoned to an unnerving, abandoned theme park to retrieve a body, Dr Kay Scarpetta is devastated to learn that the victim is a man she once loved. While teaching in Rome during the early days of her career, Scarpetta had a love affair with acclaimed astrophysicist Sal Giordano that led to a lifelong friendship. The murder scene is bizarre, with a crop circle of petals around the body, and Giordano's skin is strangely red. Scarpetta's niece Lucy believes he was dropped from an unidentified flying craft.
