Leave it to Psmith

Lady Constance Keeble has both an imperious manner and a valuable diamond necklace. The precarious peace of Blandings is shattered when her necklace becomes the object of desire for some well-connected jewel thieves - among them the Honourable Freddie Threepwood, who wants the reward money for a bookmaking business, and Psmith, the elegant socialist. On patrol with the impossible task of bringing order to Blandings is the Efficient Baxter, whose strivings lead to a memorable encounter with the castle flowerpots.
