A teenage boy vanishes on his way home. His frantic mother receives a ransom call: pay or else. The police have no leads. Enter Timothy Blake, an FBI consultant with a knack for solving impossible cases. But Blake may have met his match this time. The kidnapper is more cunning and ruthless than any he’s faced before. And he’s been assigned a new partner within the Bureau: a woman linked to the past he’s so desperate to forget. Because he has a secret --- one so dark he will do anything to keep it hidden.

For fans of "Dexter" and "Hannibal," HANGMAN introduces an unforgettable new antihero.
