Attorney, at heart, is conflicted (4)
I believe the answer is:
torn
'is conflicted' is the definition.
(I've seen this in another clue)
'attorney at heart' is the wordplay.
'at heart' indicates a hidden word (letters hidden in the heart of the clue).
'TORN' is hidden within 'attorney'.
(Other definitions for torn that I've seen before include "Lacerated - in two minds" , "Ragged" , "Removed forcibly" , "Divided" , "Ripped - undecided" .)
