Drink repercussions disheartened sleuth must accept (6,3)
I believe the answer is:
triple sec
'drink' is the definition.
(triple sec is a kind of drink)
I cannot understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for triple sec that I've seen before include "Drink" , "alcohol" , "Strong orange-flavoured liqueur - perils etc (anag)" .)
