Christmas is always a notoriously bad time for Kay Scarpetta, Chief Medical Examiner of Virginia and consulting forensic pathologist for the FBI. When Temple Gault, a cunning serial killer whose killing spree began in Richmond several years earlier, resurfaces in New York with the murder of a female transient left in frozen Central Park, Scarpetta jumps head first into the investigation. The identity of the homeless woman becomes top priority, and when it is discovered who she is, the investigation is spun into a radical new direction. Meanwhile, Gault has set his sights on Scarpetta herself...leading to one final, terrifying encounter in the fetid tunnels below the city.A fascinating book with wonderful characterization, grisly accuracy and a high-voltage, suspensful ending. The Scarpetta series is the best! When it comes to crime fiction, no one does it better than Cornwell.
