Free from blame that's evident (5)
I believe the answer is:
clear
I believe this clue is a double definition.
'free from blame' is the first definition.
(I've seen this before)
'evident' is the second definition.
(synonyms)
'that's' is the link.
(Other definitions for clear that I've seen before include "Easy to see or understand" , "Set free of charges" , "Distinct - obvious" , "Bright" , "Open; not cloudy" .)
