Ex-FBI Agent Jay Fletcher — "one of the most interesting female characters to come along in suspense fiction for quite some time" (Chicago Tribune) — is in the Witness Security Program, trying to forget all about "Billy Bones", the tabloid name for a notorious serial killer. Her vigilante pursuit of Billy and other killers landed him in a hospital for the criminally insane — and permanently ended Jay's law-enforcement career. Or so she thought. Now Billy is on the loose and e-mails a challenge: Catch me if you can. Unless his nemesis Jay is brought out of hiding and assigned to the case, he will begin a terrifying killing spree. Can Jay muster up her old manhunting skills and catch a killer before he catches her? A.J. Holt delivers another spine-tingling thriller that takes you into the mind of a madman.
