Doe is back (4)
I believe the answer is:
hind
I believe this clue is a double definition.
'doe' is the first definition.
(I've seen this in another clue)
'is back' is the second definition.

(Other definitions for hind that I've seen before include "Female beast" , "posterior" , "Female red deer" , "Be in front of this farm-worker" , "Rear - animal" .)
