Quaker captain of literature (4)
I believe the answer is:
ahab
'quaker captain of literature' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for ahab that I've seen before include "Melville's Captain" , "Jezebel was wife of this King of Israel" , "Captain -, pursuer of Moby Dick" , "Melville's whale chaser" , "Jezebel's husband, wicked king in the 'Old testament'" .)
