Gin before openings may have let down many actors (9)
I believe the answer is:
trapdoors
'have let down many actors' is the definition.
I know nothing about this answer so I can't judge whether this works.
'gin before openings' is the wordplay.
'gin' becomes 'trap' (I've seen this in other clues).
'before' is a charade indicator (letters next to each other).
'openings' becomes 'doors' (I've seen this before).
'trap'+'doors'='TRAPDOORS'
'may' is the link.
Can you help me to learn more?
(Another definition for trapdoors that I've seen is " Drops".)
