Rioter, if tested, will go back around to torch it (3,4,2)
I believe the answer is:
set fire to
'torch it' is the definition.
I know nothing about this answer so I can't tell whether this works.
'rioter if tested will go back around' is the wordplay.
'around' says the answer is hidden in the clue.
'go back' says the letters should be written in reverse.
'oteriftes' is hidden within 'rioter if tested will'.
'oteriftes' reversed gives 'SET FIRE TO'.
'to' acts as a link.
Can you help me to learn more?
(Other definitions for set fire to that I've seen before include "Light" , "torch" , "Ignite" .)
