Victim panics, concealing drums (7)
I believe the answer is:
timpani
'drums' is the definition.
(I've seen this before)
'victim panics concealing' is the wordplay.
'concealing' indicates a hidden word.
'TIMPANI' can be found hidden inside 'victim panics'.
(Other definitions for timpani that I've seen before include "orchestra members" , "Percussion instrument" , "Percussion section" , "Something making drumming noise" , "> kitchen equipment?" .)
