Cunning, masked marauder? (3)
I believe the answer is:
fox
'cunning masked marauder?' is the definition.
The answer and definition can be both people as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
This is all the clue.
Can you help me to learn more?
(Other definitions for fox that I've seen before include "Sly type" , "Charles ---, Pitt's Whig opponent" , "Cunning animal" , "Vulpine creature" , "Baffle; mammal" .)
