Tainted Nordic criminal gets brainwashed (13)
I believe the answer is:
indoctrinated
'brainwashed' is the definition.
(I've seen this before)
'tainted nordic criminal' is the wordplay.
'criminal' is an anagram indicator.
'tainted'+'nordic'='taintednordic'
'taintednordic' anagrammed gives 'INDOCTRINATED'.
'gets' acts as a link.
(Other definitions for indoctrinated that I've seen before include "Driven to accept ideas without question" , "Brain-washed" , "Convinced" .)
