Rest in sweet place with ruined houses? (4,4)
I believe the answer is:
bomb site
'place with ruined houses?' is the definition.
(where a bomb has hit)
'rest in sweet' is the wordplay.
'rest' becomes 'sit' (I've seen this in other clues).
'in' means one lot of letters goes inside another.
'sweet' becomes 'bombe' (type of dessert or sweet).
'sit' put into 'bombe' is 'BOMB-SITE'.
(Other definitions for bomb site that I've seen before include "Area of devastation" , "War-damaged area" .)
