Bully for guide behind the eye of the storm (9)
I believe the answer is:
tormentor
'bully' is the definition.
(I've seen this before)
'guide behind the eye of the storm' is the wordplay.
'guide' becomes 'mentor' (I've seen this in another clue).
'behind' means one lot of letters go next to another.
'the eye of the storm' becomes 'tor' (I can't justify this - if you can you should give a lot more credence to this answer).
'mentor' after 'tor' is 'TORMENTOR'.
'for' is the link.
Can you help me to learn more?
(Other definitions for tormentor that I've seen before include "One causes distress" , "Who would tease" , "Bully" , "cause of suffering" , "Inflictor of pain or anguish" .)
