Privileged individual jailed, back in Dartmoor (7)
I believe the answer is:
insider
'privileged individual' is the definition.
'insider' can be an answer for 'individual' (insider is a kind of individual). I'm not certain of the 'privileged' bit.
'jailed back in dartmoor' is the wordplay.
'jailed' becomes 'inside' (I've seen this before).
'back in' indicates one should take the final letters (the 'back' of the word).
The last letter of 'dartmoor' is 'r'.
'inside'+'r'='INSIDER'
Can you help me to learn more?
(Other definitions for insider that I've seen before include "one familiar with company dealings?" , "Dire sin (anag)" , "person with the lowdown" , "Doing time, right, for this" , "He's in the circle, knows the right people" .)
