Husband in house an unscrupulous sort (7)
I believe the answer is:
chancer
'an unscrupulous sort' is the definition.
(I've seen this before)
'husband in house' is the wordplay.
I cannot quite understand how this works, but
'husband' could be 'h' and 'h' is present in the answer.
'house' could be 'cancer' (Cancer is an example) and 'cancer' is found in the leftover letters.
This accounts for all the letters.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for chancer that I've seen before include "Unscrupulous sort" , "Exploiter of opportunity" , "Unscrupulous opportunist" , "One taking risks" , "opportunistic sort" .)
