House discontentment caused by such a criminal? (7)
I believe the answer is:
burglar
'house discontentment caused by such a criminal?' is the definition.
(someone who removes the contents of a house)
This is the entire clue.
(Other definitions for burglar that I've seen before include "A stealer from homes" , "Housebreaker" , "Thieving intruder" , "He takes" , "Building robber" .)
