Playwright Arthur (6)
I believe the answer is:
miller
'playwright arthur' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for miller that I've seen before include "Producer of flour" , "Arthur -, Death of a Salesman author" , "Grain grinder" , "US playwright who married Marilyn Monroe, d.2005" , "one in tale" .)
