Not scared to be involved in a fraud (8)
I believe the answer is:
unafraid
'not scared' is the definition.
(I've seen this before)
'involved in a fraud' is the wordplay.
'involved' indicates an anagram (involved can mean confusing or complex).
'in'+'a'+'fraud'='inafraud'
'inafraud' anagrammed gives 'UNAFRAID'.
'to be' acts as a link.
(Other definitions for unafraid that I've seen before include "Not fearful or scared" , "Courageous" , "Intrepid" , "Fearless" , "Not scared or apprehensive" .)
