Reminds me to reread some Dorothy L Sayers! Like you I really enjoy her writing and characters.
I go for old favourites like Gerald Durrell, Mary Wesley, Lilian Beckwith etc or read something light and undemanding with a feel-good factor. I'm going through a slumpy patch at the moment and have happily read two children's books, Bedknobs and Broomsticks and Goodnight, Mr Tom.
