French house, private, in city (4,4)
I believe the answer is:
cape town
'city' is the definition.
(city in South Africa)
'french house private' is the wordplay.
'french house' becomes 'capet' (historical French royal house).
'private' becomes 'own' (as in one's own or private belongings).
'capet'+'own'='CAPE TOWN'
'in' acts as a link.
(Other definitions for cape town that I've seen before include "Oldest S Afr. city" , "South African city" , "place in South Africa" , "Port city in South Africa" , "Legislative capital South Africa" .)
