I believe the answer is:

This is all the clue.
(Other definitions for sade that I've seen before include "Hebrew character" , "The Marquis de .... was renowned for cruelty" , "The Marquis de . . . . was noted for cruelty" , "Marquis de ..., famous for taking pleasure in pain" , "Jazz-pop group" .)
