Author Evelyn (5)
I believe the answer is:
waugh
'author evelyn' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for waugh that I've seen before include "Evelyn --, English author" , "'Scoop' author" , "Evelyn -, twentieth century English novelist" , "SECOND PART OF 19 down" , "see 26 Across" .)
