Author Philip ____ (4)
I believe the answer is:
roth
'author philip' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for roth that I've seen before include "American Jewish novelist, Philip, b. 1933" , "Philip --, US author" , "Portnoy's Complaint author, d. 2018" , "American writer" , "Author of Portnoy's Complaint, b. 1933" .)
