After a close encounter with a bomb, Detective Superintendent Andy Dalziel recuperates at the Avalon Clinic in the quaint seaside resort of Sandytown. But soon he begins to suspect that those outside the convalescent home have just as many problems as the residents. There's a psychiatrist with more to hide than his patients, a pair of powerful landowners with very different plans for putting the resort on the map, a Chinese acupuncturist with a Yorkshire accent, a skinny-dipping baronet and his ice-box sister, and a man from Dalziel's past who ought to be dead. When someone actually does turn up dead, and under the most macabre circumstances, Chief Inspector Peter Pascoe is called onto the scene. Together again, Dalziel and Pascoe investigate a baffling and complex case as further corpses make it increasingly hard for Sandytown to justify its claim to be "Home of the Healthy Holiday." But it's certainly been put on the map. . . .
