Contest Question for October 15

Today is the birthday of P.G. Wodehouse, famous for writing nearly 100 volumes of comic fiction.

Wodehouse is best known for his novels featuring Bertie Wooster and his butler Jeeves. But does anyone out there know Wodehouse’s other best-known series of comic novels? Trivia bragging rights for the day if you can name the country estate at which this second series of novels is set.
