"Peter Pan” author (6)
I believe the answer is:
barrie
'peter pan author' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for barrie that I've seen before include "J. M. -, Peter Pan author" , "Scottish playwright" , "Peter Pan's creator" , "Children's writer" , "J. M. -, Peter Pan creator" .)
