Clean hands - you can't be prosecuted for that! (9)
I believe the answer is:
innocence
'clean hands you can't be prosecuted for that' is the definition.
The definition suggests a singular noun which matches the answer.
This is the entire clue.
Can you help me to learn more?
(Other definitions for innocence that I've seen before include "Naivety" , "Uncorrupted state" , "Absence of guilt" , "probity" , "lack of conviction" .)
