Martin —, author of novels Yellow Dog and Other People (4)

I believe the answer is:

amis

(Other definitions for amis that I've seen before include "Author Kingsley or Martin" , "Kingsley -, English author (Lucky Jim)" , "English writer" , "Kingsley, Martin or John" , "Author of Lucky Jim, d.1995" .)

I've seen this clue in The Mirror.
