When a valuable scarab belonging to an American millionaire is absent-mindedly stolen by Lord Emsworth, young writers Ashe Marson and Joan Valentine are tasked with infiltrating Blandings Castle to retrieve it. Meanwhile, vacuous Freddie Threepwood worries that some compromising letters may scupper his engagement to the millionaire's daughter. Wodehouse's comic masterpiece combines above and below stairs pretensions with all the fun of a romantic thriller.
