Nice friends (4)
I believe the answer is:
amis
'nice friends' is the definition.
('friends' in French eg in Nice)
This is the entire clue.
(Other definitions for amis that I've seen before include "Author of Lucky Jim, d.1995" , "Kingsley -, English author (Lucky Jim)" , "Author Kingsley or Martin" , "English writer" , "Martin --, Eng. author" .)
