Part of the foot; rogue (4)
I believe the answer is:
heel
This clue is a double definition.
'part of the foot' is the first definition.
(I've seen this in another clue)
'rogue' is the second definition.
(I've seen this before)
(Other definitions for heel that I've seen before include "order to dog" , "Rogue" , "bank" , "Back part of the foot" , "Cad,bounder, blackguard" .)
