What is the name of Miss Marple's nephew?

Miss Marple’s nephew is Raymond West, a well-known writer who appears in several of Agatha Christie’s stories.

Raymond is Jane Marple’s nephew and one of her recurring family connections. He is introduced in “The Tuesday Night Club,” the first story in the collection The Thirteen Problems, where Miss Marple joins a group discussing seemingly unsolvable crimes. Raymond is more interested in literature than in his aunt’s investigations, and he sometimes underestimates how sharply she observes human behaviour.

Raymond is married to Joan West, an artist, and they have two sons, David and Lionel. Although he is not usually part of the central detective work, his family and professional life occasionally provide Miss Marple with useful information or a reason to travel.

Readers sometimes confuse Raymond West with Christie’s other recurring characters, including Captain Arthur Hastings, Poirot’s associate, and Tommy Beresford, one half of the adventuring detective couple Tommy and Tuppence. Raymond belongs specifically to the Miss Marple family circle.
