Accuse of a crime (6)
I believe the answer is:
charge
'accuse of a crime' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for charge that I've seen before include "15 - or required payment" , "running cost" , "Accuse or rush forward" , "Formally accuse (someone)" , "Amount to pay - attack" .)
