Serpent's Point in South Devon is the focus of local legends. The large house on the headland is shrouded in an ancient tale of evil, and when a woman is found strangled on the coastal path, DI Wesley Peterson is called to investigate.

The woman had been house-sitting at Serpent's Point and Wesley is surprised to discover that she was conducting an investigation into unsolved missing person cases. Could these enquires have led to her murder?

While the case takes Wesley to Yorkshire and the Cotswolds, archaeologist Neil Watson is making a dramatic discovery of his own in the fields near the house.

When a skeleton is uncovered, the pressure rises to find a killer, and Wesley and Neil realise that Serpent's Point holds more secrets than anyone could have imagined.
