Lord Emsworth's idyllic demesne, Blandings Castle, is as usual overrun with overbearing sisters, overefficient secretaries, and the lovestruck; even worse, an alleged old flame has appeared, determined to put an end to the Earl's peaceful, pig-loving existence.

After saving his master so often in the past, Jeeves may finally prove to be the unwitting cause of Bertie Wooster's undoing when the Junior Ganymede, a club for butlers in London's West End, requires its members to provide details about their employers. When information is inadvertently revealed to a dangerous source, it falls to Jeeves to undo the damage.
