Dr Ruth Galloway returns to the moody and beautiful landscape of North Norfolk to confront another killer. The Night Hawks, a group of metal detectorists, are searching for buried treasure when they find a body on the beach in North Norfolk. At first Nelson thinks that the dead man might be an asylum seeker but he turns out to be a local boy recently released from prison. Ruth is more interested in the treasure, a hoard of Bronze Age weapons. A devastating new case for our favourite forensic archaeologist.
