A Most Contagious Game
From fantasticfiction dot com: "When Thomas Harding retired to the Manor House of Easterbrook he soon discovered that it contained rather more than the house-agents had advertised. It became apparent, more-over, that Easterbrook, despite its outward serenity, had more than one skeleton in the parish cupboard. What for instance was the guilty secret which the village seemed to share with the ancient family of the Barbarys, and what connection could there be between this and the handiwork of an Elizabethan craftsman? Intrigued by these questions, Thomas Harding found himself helping to solve two crimes at once-the one modern, and the other one-and-a-half centuries old. And it was only after he had found the answers to these questions that the various skeletons could he laid to rest." This is Aird's only book that does not feature Detective Inspector Sloan and the Calleshire police, and like her other mysteries, it does not disappoint.
