"The Old Devils" author (4)
I believe the answer is:
amis
'the old devils author' is the definition.
(I've seen this in another clue)
This is all the 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" .)
