1958 Pulitzer author (4)
I believe the answer is:
agee
'1958 pulitzer author' 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" .)
