Dr Rory, a Scotsman, could be working here (4,3,8)

I believe the answer is:

ross and cromarty

'working here' is the definition.
The definition suggests a singular noun which matches the answer.

'dr rory a scotsman could be' is the wordplay.
'could be' indicates anagramming the letters.
'dr'+'rory'+'a'+'scotsman'='drroryascotsman'
'drroryascotsman' with letters rearranged gives 'ROSS AND CROMARTY'.

(Another definition for ross and cromarty that I've seen is " Old county".)

I've seen this clue in The Independent.
