Wife of Menelaus (5)
I believe the answer is:
helen
'wife of menelaus' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for helen that I've seen before include "Spartan beauty" , "Famous beauty of Troy" , ""The face the launched 1,000 ships"" , "Woman abducted to Troy" , "beautiful woman" .)
