Ned is not part of deception - and there's a kind of justice in that (6)
I believe the answer is:
poetic
'justice in that' is the definition.
'poetic' can be an answer for 'justice' (thesaurus). I am not sure about the rest of the definition.
'ned is not part of deception and there's a kind' is the subsidiary indication.
I cannot really see how this works, but
'part' could be 'ti' (ti is a kind of part) and 'ti' is present in the answer.
'of' could be 'o' and 'o' is present in the answer.
The remaining letters 'pec' is a valid word which might be clued in a way I don't see.
This may be the basis of clue (or it may be nonsense).
'of' is the link.
Can you help me to learn more?
(Other definitions for poetic that I've seen before include "Flowery" , "Expressed in verse" , "Having rhythm and beauty" , "Ice pot (anag.)" , "Written in verse" .)
