Miss Marple receives a most interesting request from Mr. Jason Rafiel, with whom she’d struck an acquaintance some years before. He would like her to solve a crime but, does not tell her what it might be, who might have been involved or where it might have occurred. In fact, he can’t be sure that a crime was committed at all. The only information she gets is a booking on a tour of stately homes and gardens so, along with her nephew and godson Lionel, she sets off to see what she can learn. When they reach the village of Abbey Ducis, it begins to make sense. Not only did Mr. Rafiel live in the area it is also where his son Michael was accused, though never convicted, of murdering his fiancée, Verity Hunt. Father and son were long estranged but Michael lives rough and has so ever since. There is also the apparent coincidence that another young woman, Nora Brent, went missing at the same time as Verity and was last being seen in Michael Rafiel’s car. When Elizabeth Temple, a fellow traveler on the tour, is killed Miss Marple has another key piece of information to help solve the puzzle.
