Butler of fiction (5)
I believe the answer is:
rhett
'butler of fiction' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for rhett that I've seen before include "Scarlett O'Hara's lover-husband ..... Butler" , "..... Butler was Scarlett O'Hara's lover" , "Hero of the above" .)
