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 am not sure about this - if you are sure you should believe this answer much more).
'let' becomes 'hire' (I've seen this in another clue).
'shrops'+'hire'='SHROPSHIRE'
'has address centrally within mall perhaps' acts as a link.
I am not very happy about this link. 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" .)
