The Code of the Woosters is my favorite Wodehouse novel. It is part of the Bertie Wooster and Jeeves series, and it involves an aunt, several unlikely engagements, a comic fascist, and a cow creamer. Aunts, engagements, and comic fascists are common in the Jeeves books, but the cow creamer is unique and very memorable. I read most of the other Jeeves books many years ago, but I don't remember which is which, and there is the extra annoyance that some of the books have different US vs UK titles. All the Jeeves books are fun. It doesn't matter what order you read them in.
If you are fond of pigs, the Blandings Castle books are cute, although if you don't find overblown discussions of pigs to be the funniest thing ever, you may want to give that series a miss. I enjoyed
Heavy Weather, but the pig jokes got very very old. I'd say something about flogging a dead horse, but that would be too many farm animals for one post. Wodehouse can also be a bit too interested in golf, although some people don't mind that sort of thing.
Wodehouse wrote tons of books. You will have lots to enjoy. Now I want to download a few more from Project Gutenberg, too.
