Miss Marple, living a quiet life in St Mary Mead, is saddened to hear of the death of Jason Rafiel. Not that they were friends - the old financier was much too irascible and self-centred for friendship - but they had once been allies in solving a series of murders that took place on the tiny Caribbean island of St Honoré. She is therefore greatly surprised by a summons to the dead man's solicitor, where she receives a bizarre challenge in the form of a posthumous letter. According to Mr Rafiel, a crime has been committed, and her task is to investigate and solve it. If she succeeds, she stands to inherit twenty thousand pounds. But what is the crime, and who was involved? Left literally without a clue, can even the ever-observant Miss Marple succeed in solving the most impossible case of her life? June Whitfield stars as Miss Marple, with David Swift and Jill Balcon, in this full-cast dramatisation of one of Agatha Christie's most baffling mysteries. 2 CDs. 2 hrs 15 mins.
