In a British seaside holiday resort at the height of the season, you would expect to find a promenade and a pier, maybe some donkeys, 'Kiss-Me-Quick' hats, candy floss and kids building sandcastles. You would not expect to find a naked corpse, punctured with stab wounds, lying on the sand. Chief Inspector George Gently is called in to investigate the disturbing murder. The case has to be wrapped up quickly to calm the nerves of concerned holidaymakers. No one wants to think that there is a maniac on the loose in the town but with no clothes or identifying marks on the body, Gently has a tough time establishing who the victim is, let alone finding the killer.
