A missing girl spells danger for P.I. Mark Banning!
For Baltimore detective Mark Banning, the case starts out as typical, as a standard missing-persons affair: a man seeks his help in finding his daughter, who disappeared after meeting with a man she met online. Mark enlists the assistance of his police detective friend Ed Taylor—but when they find the dead bodies of the girl, the man she met online, and the girl's father besides, the case becomes far more complicated than they thought it could be. There was another involved, as well: a mysterious phantom witness who may have the answer to the entire story. But the closer Banning gets to learning the identity of the killer, the more he realizes that he himself is marked to become the next body to be found!
