I could pretend that The Code of the Woosters is about making fascists look like idiots – and it is, a teeny-tiny bit. But really its about the goofy adventures of Bertie Wooster, getting engaged to two different young ladies, neither of whom he wants to marry (neither of whom want to marry him, either), and how Jeeves, the amazing butler somehow makes everything better.
All the Jeeves books are fun and light and worth a laugh. Definitely recommended.
