The Clothes They Stood Up In, by Alan Bennett

Bennett's real talent must lie in drama, because, as pleasant as this simple novella was, it could hold no candle, in literary merit, depth, or even entertainment value to History Boys. The story of a bourgeois couple who return home to find all their stuff missing ultimately lacked soul, though its tidy moral of love-yourself-explore-your-surroundings was heartening enough. I don't recommend it, though; any number of other books share its moral, and at least one shares part of its plot (The Accidental, a far better work). Just go see History Boys instead.
