Drive home, back into awful torment in part of Paris (10)
I believe the answer is:
montmartre
'part of paris' is the definition.
(I've seen this before)
'drive home back into awful torment' is the wordplay.
'drive home' becomes 'ram' (to ram something in is to drive it home).
'back' says the letters should be written backwards.
'into' means one lot of letters goes inside another.
'awful' is an anagram indicator.
'ram' reversed gives 'mar'.
'torment' is an anagram of 'monttre'.
'mar' put inside 'monttre' is 'MONTMARTRE'.
'in' is the link.
(Other definitions for montmartre that I've seen before include "high point for the capital" , "Paris area" , "District of Paris, associated with many artists" , "painterly quarter" , "part of Paris" .)
