Jeeves is on holiday in Herne Bay, and while he's away the world caves in on Bertie Wooster. For a start, he's astonished to read in The Times of his engagement to the mercurial Bobbie Wickham. Then at Brinkley Court, his Aunt Dahlia's establishment, he finds his awful former head master in attendance ready to award the prizes at Market Snodsbury Grammar School. And finally the Brinkley butler turns out for reasons of his own to be Bertie's nemesis in disguise, the brain surgeon Sir Roderick Glossop.

With all occasions informing against him, Bertie has to hightail it to Herne Bay to liberate Jeeves from his shrimping net. And after that, the fun really starts.
