New Year's Eve and the final murder scene of Virginia's bloodiest year takes Scarpetta thirty feet below the Elizabeth River's icy surface. Dr. Scarpetta receives a phone call reporting the death of investigative reporter Ted Eddings, who was found dead in diving gear amongst the Navy's reserve fleet. Was Eddings probing the frigid depths of the inactive shipyard for a story, or simply diving for sunken trinkets—and why did Scarpetta receive the phone call reporting the death before the police were notified? The case leads Scarpetta, her niece Lucy, and police captain Pete Marino into a terrorist plot that threatens thousands of lives.
