In a coastal village in Wales, someone is committing the perfect crime: people are disappearing without a trace. An elderly woman is the most recent disappearance. A day later, police find her body washed up on the beach. Senior officers record it as death by misadventure, but Village Constable Gwyn Thomas is certain her death and the other disappearances are connected. Police suspicion is inevitable, but as with many crimes, an unintended consequence follows. This time the consequence has a name-Bethan, the dead woman's niece. When she arrives from London to claim her inheritance, she refuses to accept her aunt's death was accidental. Bethan begins hunting down and questioning village residents who might have information. As the puzzle pieces begin to fall into place, suddenly the tables are turned. She discovers she is no longer the hunter-she is the prey.
