Wolfe the detective (4)
I believe the answer is:
nero
'wolfe the detective' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for nero that I've seen before include "Famous fiddler" , "Roman emperor infamous for his cruelty" , "Emperor (who fiddled while Rome burned?) d. AD68" , "He's reputed to have fiddled while Rome burned" , "Matricidal emperor" .)
