Villains' looks (6)
I believe the answer is:
sneers
'villains' looks' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for sneers that I've seen before include "Jeers, derides" , "Expresses cynical contempt" , "Smiles contemptuously" , "Makes scornful remark, derides" , "Contemptuous or scornful remarks" .)
