So true. David Niven was a very funny man. I loved his writing. I'm quite solidly into fantasy now, and I have an established favourite. Her name is Mercedes Lackey, and I got started on her Fairy Godmother stories. They are a humourous twist on the the tales of the fairy godmother of early children's stories, and she does a marvelous job.
Unfortunately, I think I'm almost at an end of her books. So sad! She is so good, and has written a lot of books in different series. If you care for that sort of thing, look her up at the nearest library or on the computer.
