Psmith is another character with a few books, The P is silent like in psychology or ptarmigan I have not read all these though they were written early in his career before he really learned to write well rounded women characters I am sure they are good anyhow.

1 Mike also known as Enter Psmith
2Psmith and the city
3 Psmith journalist
4 Leave it to Psmith

The Blandings Castle series is also really good probably the next best after Wooster and Jeeves

1 Something fresh also known as something new
2 Leave it to Psmith Psmith goes to Blandings and I think this is where it would be in the order of things
3 Summer lightning also known as Fish Preferred
4 Heavy weather is the second part of Summer lightning
5 I am working off memory here and I Have not read all the Blandings series either there are a bunch of short stories I think come next published in these books in no particular order "Lord emsworth and others" "Blandings Castle and elsewhere" "A crime wave at Blandings"

There are another 6-7 Blandings books that come after and I have only read 2 of them "Full moon" and "Pigs have wings"
