What is the name of Miss Marple's nephew, who appears in several of Agatha Christie's novels?

Joan Hickson was THE Jane Marple...as if she stepped off the pages. Interestingly, Miss Hickson played the housekeeper/cook in"Murder, She Said", starring Margaret Rutherford as Miss Marple (as she did several times). Wonderful actress but NOT Miss Marple. Do please, read the books. There are many more characters than Miss Marple, M.Poirot and Tommy & Tuppence Beresford as protagenists. Just avoid "Black Coffee".
