If you mean actress who plays Miss Marple, then Joan Hickson is my Miss Marple.

If you mean favorite Agatha Christie novels, I like And Then There Were None and A Carribean Mystery and The Murder of Roger Ackroyd.

I prefer Miss Marple to Poirot, but I like Poirot, too. I like to write about the friendship between Miss Marple and Dolly Bantry and Miss Marple and her revolving door of housemaids.
