"The African Queen” scriptwriter (4)
I believe the answer is:
agee
'the african queen scriptwriter' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for agee that I've seen before include "American writer" , "off the straight on Princes Street" , "off the straight at Gleneagles" , "In Ayr not straight" .)
