Wexford perhaps sent cop around in Ireland (9)
I believe the answer is:
inspector
'wexford' is the definition.
(Inspector Wexford is a fictional detective)
'sent cop around in ireland' is the wordplay.
'around' indicates an anagram.
'in' means one lot of letters goes inside another.
'ireland' becomes 'ir' (abbreviation for Ireland).
'sent'+'cop'='sentcop'
'sentcop' with letters rearranged gives 'nspecto'.
'nspecto' inserted inside 'ir' is 'INSPECTOR'.
'perhaps' acts as a link.
(Other definitions for inspector that I've seen before include "auditor" , "I look over" , "Policeman; compliance official" , "Examining official" , "reviewer" .)
