November in an Italian city: go to bed (4,2)
I believe the answer is:
turn in
'go to bed' is the definition.
('turn in' can be a synonym of 'go to bed')
'november in an italian city' is the wordplay.
'november' becomes 'n' (phonetic alphabet: alpha, bravo, charlie etc.).
'in' is an insertion indicator.
'an italian city' becomes 'turin' (I've seen this before).
'n' put into 'turin' is 'TURN-IN'.
(Other definitions for turn in that I've seen before include "Prepare for sleep" , "Hit the hay" , "Go to bed, changing direction" , "Retire to bed" , "Go to bed (informal)" .)
