Just the outskirts of Dundee (3)
I believe the answer is:
due
'just' is the definition.
(I've seen this in another clue)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for due that I've seen before include "Unpaid or expected" , "Scheduled to arrive" , "Owed, or payable immediately" , "Requisite" , "Expected, scheduled" .)
