Follow back inside pagoda (3)
I believe the answer is:
dog
'follow' is the definition.
(dog can mean to follow or torment)
'back inside pagoda' is the wordplay.
'back' is a reversal indicator.
'inside' indicates the answer is hidden within the clue.
'god' can be found hidden inside 'pagoda'.
'god' in reverse letter order is 'DOG'.
(Other definitions for dog that I've seen before include "Contemptible man" , "Hound" , "'Every . . . has its day'" , "A pet; its life prov. wretched" , "'Every ... is allowed one bite'" .)
