Quiet desire for witch hunt? (5)
I believe the answer is:
purge
'witch hunt?' is the definition.
'quiet desire' is the wordplay.
'quiet' becomes 'p' (music symbol for 'piano').
'desire' becomes 'urge' (I've seen this before).
'p'+'urge'='PURGE'
'for' acts as a link.
(Other definitions for purge that I've seen before include "Eliminate or expiate" , "Purify from sin or guilt" , "Get rid of unwanted elements" , "Thoroughly clean" , "Elimination of "undesirables"" .)
