Daniel Garvie was only a child himself when he saw the lost little boy. And because he was too frightened to help him, one of the world's most notorious serial killers got away.

Years later, Dan has a successful career as a criminal psychiatrist, unpicking the reasons behind the very darkest of human behaviours. But when his father disappears, Dan is forced to return to the small island where he grew up. A place where all the ghosts and monsters he thought he'd left behind him remain all too real. 

It might be a chance for him to find redemption.

Or he might be walking straight into a trap.
