Woman tempted in Nineveh (3)
I believe the answer is:
eve
'woman tempted' is the definition.
'in nineveh' is the wordplay.
'in' says the answer is hidden in the clue.
'EVE' can be found hidden inside 'nineveh'.
(Other definitions for eve that I've seen before include "comes before Jan. 1st" , "Adam's partner" , "Adam & - -" , "Brink" , "First mate" .)
