Never has DI Wesley Peterson witnessed such a bizarre crime scene. A man has been brutally murdered by two precise wounds to his neck and his body drained of blood.

It seems that the victim, Charles Marrick, was not a popular man in the Devon area and Wesley doesn’t have a shortage of suspects. But then another victim is found killed in an identical fashion and a third body is also discovered.

As if Wesley didn’t have enough to investigate, Wesley’s friend, archaeologist Neil Watson, begins to receive disturbing anonymous letters about macabre events at a medieval abbey. The gory details bare resemblance to the recent murders and Neil fears they are being sent by the killer.
