Son finding refusing starter brings temptation (9)
I believe the answer is:
seduction
'temptation' is the definition.
(seduction is a kind of temptation)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for seduction that I've seen before include "Allure" , "Deceptive activity" , "sexual temptation" .)
