The beauty of justice (8)
I believe the answer is:
fairness
This clue is a double definition.
'the beauty' is the first definition.
(fairness is a kind of beauty)
'justice' is the second definition.
(I know that fairness is a type of justice)
'of' acts as a link.
(Other definitions for fairness that I've seen before include "Impartiality, justice" , "Equity, justice" , "Equality" , "the fine, dry state of the weather" , "Beauty - justice" .)
