Create a disturbance (5,4)
I believe the answer is:
raise cain
'create a disturbance' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for raise cain that I've seen before include "create problem" , "Make a big commotion (5.4)" , "Cause a noisy disturbance" , "Create a rumpus, elevate murderer" , "Make an angry fuss" .)
