Spies going north and south (4)
I believe the answer is:
sees
This clue is a double definition.
'spies' is the first definition.
(I've seen this in another clue)
'going north and south' is the second definition.
(Other definitions for sees that I've seen before include "Notices" , "Clocks" , "Dioceses; views" , "Spots" , "Bishops' dioceses" .)
