Domestic crime within a patient guy (6,3)
I believe the answer is:
inside job
'domestic crime' is the definition.
'inside job' can be an answer for 'crime' (I've seen this before). I am unsure of the 'domestic' bit.
'within a patient guy' is the wordplay.
'within' becomes 'inside' (synonyms).
'a patient guy' becomes 'job' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'inside'+'job'='INSIDE JOB'
Can you help me to learn more?
(Other definitions for inside job that I've seen before include "Sort of crime" , "Type of crime" , "Crime with collusion" , "criminal activity" , "Crime aided by employees" .)
