No arm twisted in policeman's territory (5)
I believe the answer is:
manor
'policeman's territory' is the definition.
The answer and definition can be both related to property as well as being singular nouns.
Maybe you can see a link between them that I don't see?
'no arm twisted' is the wordplay.
'twisted' indicates anagramming the letters.
'no'+'arm'='noarm'
'noarm' with letters rearranged gives 'MANOR'.
'in' is the link.
Can you help me to learn more?
(Other definitions for manor that I've seen before include "Mansion of a wealthy person" , "Large country house for Roman" , "Nobleman's land" , "police area" , "Grand but strange Roman house" .)
