Her country? Not even his (2-4-4)
I believe the answer is:
no-mans-land
'her country?' is the definition.
(cryptic definition)
'not even his' is the wordplay.
I cannot really see how this works, but
'not' could be 'no' (I've seen this in other clues) and 'no' is located in the answer.
This may be the basis of clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for no-mans-land that I've seen before include "disputed territory" , "Unoccupied zone" , "Area between two opposing armies" , "Neutral area" , "Ambiguous region" .)
