Whaler of fiction (4)
I believe the answer is:
ahab
'whaler of fiction' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for ahab that I've seen before include "Jezebel's husband, wicked king in the 'Old testament'" , "Ancient king of Israel" , "Jezebel's husband - Moby Dick's hunter" , "sea captain" , "Israelite king" .)
