Villain, wrongdoer (9)
I believe the answer is:
miscreant
I believe this clue is a double definition.
'villain' is the first definition.
(I've seen this in another clue)
'wrongdoer' is the second definition.
(I know that miscreant is a type of wrongdoer)
(Other definitions for miscreant that I've seen before include "culprit" , "Offender" , "criminal" , "behaving unlawfully" , "scoundrel" .)
