Children's author Blyton (4)
I believe the answer is:
enid
'children's author blyton' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for enid that I've seen before include "Dine out on this girl's name also" , "Miss Blyton" , "Geraint's loved one" , "Woman" , "Writer of children's books, d. 1968" .)
