I believe the answer is:
agee
'the african queen screenwriter james' 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 "off the straight at Gleneagles" , "American writer" , "In Ayr not straight" , "off the straight on Princes Street" .)
