There is something particularly unsettling about the body most recently found in Wrightsburg's forest. The murderer left a watch on his victim's wrist with a strange symbol on it—an act that suggests that this is the first of more killings to come. The method is cold and methodical: his victims continue to be found wearing a watch set to a particular time of day. When a copy-cat killer emerges, the case has become too complicated for the local police department, and former Secret Service agents Sean King and Michelle Maxwell are called into the investigation.
