first name that came to my head when I read the thread title was Stieg Larsson. I haven't even read the 4th book, I might look into it, but I agree with you, I enjoyed the first 3 very much and I think I read somewhere that he had planned to make it an 8 books series about Lisbeth Salander? it's really a pity he died so young.
I would have loved to read more by Oscar Wilde as well.
