Felon done for hiding in city (6)
I believe the answer is:
london
'city' is the definition.
(I know that London is a city)
'felon done for hiding' is the wordplay.
'hiding' indicates the answer is hidden within the clue.
'LONDON' is hidden in the letters of 'felon done for'.
'in' is the link.
(Other definitions for london that I've seen before include "British capital" , "Home of Cockney" , "City of Piccadilly" , "- Clay; - pride; - plane" , "English capital" .)
