Sadist or torturer hiding pervert (7)

I believe the answer is:

distort

'pervert' is the definition.
(I've seen this before)

'sadist or torturer hiding' is the wordplay.
'hiding' says the answer is hidden in the clue.
'DISTORT' is hidden within 'sadist or torturer'.

(Other definitions for distort that I've seen before include "Deform" , "Warp" , "Twist out of shape" , "bend" , "turn crooked" .)

I've seen this clue in The Independent.
