An act of duplicity? (4)
'an act' is the definition.
(duet is a kind of act)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for duet that I've seen before include "Work for two performers" , "Paired performance" , "Two singers performing together" , "Composition for two performers" , "Music for two" .)
'act of duplicity?' is the definition.
'duo' can be an answer for 'act' (I have seen 'Double act ' mean 'duo' so perhaps 'act' could also mean 'duo'). I'm unsure of the 'of duplicity?' bit.
I cannot understand how the remainder of the clue works.
