County has address centrally within mall perhaps to let (10)
I believe the answer is:
shropshire
'county' is the definition.
(I've seen this before)
'to let' is the wordplay.
'to' becomes 'shrops' (I can't explain this - if you can you should give a lot more credence to this answer).
'let' becomes 'hire' (I've seen this in another clue).
'shrops'+'hire'='SHROPSHIRE'
'has address centrally within mall perhaps' acts as a link.
This may not be correct. Some or all of it may belong to another bit of the clue.
Can you help me to learn more?
(Other definitions for shropshire that I've seen before include "county" , "Region of England" , "largely rural location" .)
