A well-known lawyer is found dead at the Tintagel castle site. Aside from a small puncture wound on his upper arm, the police find no traces. There are no witnesses, and Detective Chief Superintendent Bob Hamilton is stranded on the Scilly Islands due to a storm, leaving the investigators baffled. Then a second murder occurs. For the second time, Bob Hamilton, head of the criminal police of Devon and Cornwall, investigates in the murderously beautiful landscape of southwest England.
