Captain in a whale of a tale? (4)
I believe the answer is:
ahab
'captain in a whale of a tale' 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 "Israelite king" , "Captain -, pursuer of Moby Dick" , "Husband of Jezebel" , "Jezebel's husband, wicked king in the 'Old testament'" , "Moby Dick's pursuer" .)
