Area of expertise for bloke in East Midlands town (9)
I believe the answer is:
mansfield
'midlands town' is the definition.
(I've seen this before)
'area of expertise for bloke in east' is the wordplay.
I cannot quite understand how this works, but
'area' could be 'field' (field is a kind of area) and 'field' is found within the answer.
'bloke' could be 'man' (I've seen this in other clues) and 'man' is found in the answer.
A single letter 's' remains which might be clued in a way I don't see.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for mansfield that I've seen before include "Midlands town" , "Midland town" , "Book by Jane Austen" , "Name of former pin-up" , "Novel, '-- Park'" .)
