Examination of a country girl (7)
I believe the answer is:
perusal
'examination' is the definition.
(I've seen this before)
'a country girl' is the wordplay.
'a country' becomes 'peru' (Peru is an example).
'girl' becomes 'sal' (feminine given name**).
'peru'+'sal'='PERUSAL'
'of' is the link.
(Other definitions for perusal that I've seen before include "Careful look" , "Study or scrutiny" , "Inspection" , "Careful examination" , "A casual read or study" .)
