Agitator reduced temperature at Moscow mint? (12)
I believe the answer is:
troublemaker
'agitator' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for troublemaker that I've seen before include "Agitator" , "Deliberate causer of problems" , "Inciter of unrest" , "source of agitation" , "One inciting unrest" .)
