Fictional Wolfe (4)
I believe the answer is:
nero
'fictional wolfe' 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 "Notorious Roman emperor, d. AD 68" , "Emperor said to have fiddled as Rome burned" , "Roman Emperor, 54-68 AD" , "Roman tyrant" , "He's reported to have fiddled while Rome burned" .)
