The first victim is attacked in her home. Tied to her bed. Forced to watch every unspeakable act of cruelty - but unable to scream. The second murder is even more twisted. Signed, sealed, and delivered with a message for the police, stuffed in the victim's throat. A fractured nursery rhyme that ends with a warning: "There will be more". For detective Jack Murphy, it's more than a threat. It's a personal invitation to play.

From the moment he sees the young woman's body in her hotel bathtub, homicide detective Jack Murphy knows he's looking at a truly demented but brilliantly designed puzzle. 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.
