Ariadne Oliver, Queen of Crime Fiction, has been asked to devise a murder hunt at Nasse House, the home of Sir George Stubbs. But she begins to suspect that someone is manipulating the scenario of her game and fears that something very sinister is being planned. She sends for her old friend Hercule Poirot. At first he is not inclined to take her very seriously, but soon a series of events propels him to change his mind. Then, suddenly, all of Ariadne's worst fears are realized when the girl playing the part of the murder victim is found strangled in the boat house. For Hercule Poirot, the murder hunt has become a grim reality. This BBC Radio 4 full-cast dramatization stars John Moffatt as the great Belgian detective, with Julia McKenzie as Ariadne Oliver.
