"Camelot" actor Franco (4)
I believe the answer is:
nero
'camelot actor franco' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for nero that I've seen before include "Roman emperor who fiddled while Rome burned" , "Wicked fiddler" , "Roman Emperor notorious for vice and luxury" , "Famous fiddler" , "Ancient Roman emperor" .)
