The Chronicles of St. Mary's : Murder at Martingale Manor

God rest ye merry gentlefolk, it's time for the traditional St Mary's Christmas jump - this year to Martingale Manor, where a murder mystery is unfolding... It's nearly Christmas and Leon has had a Brilliant Idea. A holiday - to enable a very reluctant Max to recover from her recently acquired injuries. Devon, 1924 - Martingale Manor. Lovely surroundings, good food and very pleasant guests. Or, as they soon become known - the usual suspects. They mysterious older woman. The absent-minded clergyman. The doctor. The military man. The charming young couple. Because this is the world of Agatha Christie and before long one of them is dead. And when the police arrive, the only person without a cast-iron alibi is. . . Leon. It was supposed to be a holiday, for heaven's sake.
