Wife of Orpheus (8)
I believe the answer is:
eurydice
'wife of orpheus' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for eurydice that I've seen before include "Badly-looked-after wife" , "Wife of Orpheus, who sought her in the underworld" , "In Greek mythology, the wife of Orpheus" .)
