The criminal is also a healer (9)
I believe the answer is:
therapist
'a healer' is the definition.
(I know that healer can be written as therapist)
'the criminal is also' is the wordplay.
'criminal' becomes 'rapist' (rapist is a kind of criminal).
'is also' says to put letters next to each other.
'the'+'rapist'='THERAPIST'
(Other definitions for therapist that I've seen before include "one in care" , "healing type" , "Medical practitioner" , "nurse" , "One giving treatment" .)
