Writer Harper (3)
I believe the answer is:
lee
'writer harper' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for lee that I've seen before include "Bruce ___, martial arts ace" , "The side that's sheltered from the wind" , "Sheltered from the wind in Cork, perhaps" , "Robert E. - - , US hero" , "The sheltered side of something" .)
