The Code of the Woosters: Jeeves to the Rescue

Wonderful, as always! If you've seen the BBC series, then the plot will be familiar (I forget which episodes, but I think they did a two-parter following the novel). On Goodreads they make it clear that it's #7 but a lot of the editions out in the world don't necessarily say that; still, Bertie (the narrator) does his best to catch you up with everything that came before if you haven't read the other books & stories.
