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