Period just before she was tempted (3)
I believe the answer is:
eve
I believe this clue is a double definition.
'period just before' is the first definition.
(I've seen this in another clue)
'she was tempted' is the second definition.
(I've seen this in another clue)
(Other definitions for eve that I've seen before include "Adam's partner" , "Brink" , "Female" , "Threshold" , "Day before (an event)" .)
