Hellespont victim (7)
I believe the answer is:
leander
'hellespont victim' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for leander that I've seen before include "In Greek myth, the lover of Hero" , "Ill-fated lover" , "Hero-worshipper" , "youth who drowned" , "man who went under" .)
