Quiet year in unusual city post - one won’t work for dictator (4,6)
I believe the answer is:
Here is my best explanation:
'one won't work for dictator' is the definition.
I can't judge whether this defines the answer.
'quiet year in unusual city post' is the subsidiary indication.
'quiet' becomes 'p' (music symbol for 'piano').
'year' becomes 'y'.
'in' is an insertion indicator.
'unusual' is an anagram indicator.
'citypost' is an anagram of 'cotypist'.
'py' going into 'cotypist' is 'copytypist'.
(Another definition for copy typist that I've seen is "one used to transcribe documents".)
