Yeah Wimsey inspired quite a bit of imitation, ranging from the good (Greenwood's Phryne Fisher is an excellent female Wimsey) to the mediocre (the later Vance as you mentioned). Rather like Holmes.
I'm reading the entire
Lord Darcy series presently and there's a definite Wimsey/Bunter vibe there.
Excellent stories too, I wonder what Randi thought of his cameo as Chief Forensic Sorcerer of London?
Lilian Jackson Braun wrote
The Cat Who series; I liked them despite the efforts she went to pad out the quite short stories.
I've read a couple of Irene Kelly' books, I like them but she started using the superman serial killer meme a little much.
If you like SF/F you might like the
Lord Darcy stories; basically a blend of Wimsey and Holmes in an alternate world with Victorian technology and scientific magic.
And a sorcerer
never does it.
