She's been drained of blood. Missing her left hand—and the killer left a special message just for him. Hours later, he sees her severed hand arranged on a second victim's body. The newspaper has the gruesome details. The FBI has a theory. But only Murphy knows how hard he'll have to push—and how much he'll have to risk—to thwart the killer's twisted game.
