Miss Marple number three. Miss Marple's dear friends, Colonel and Mrs Bantry, wake up one morning to find the (dead) body of a young blonde in their library. Naturally the village begins to talk and of course they all think that it must be a woman that Colonel Bantry was carrying on with. Cue Miss Marple, on a quiet crusade to clear his name. Out of a fair number of missing girls, the woman is identified as a young dancer from a nearby hotel/resort by a relative she was staying and working with. A couple of days later a burnt car with the body of another girl is discovered, confusing everything.
Naturally Miss Marple saves the day, explaining all those odd little twists and turns that are really very simple, once you know what happened.
