Skill in fraud on its way (8)
I believe the answer is:
starting
'on its way' is the definition.
'skill in fraud' is the wordplay.
'skill' becomes 'art' (both can mean a talent).
'in' is an insertion indicator.
'fraud' becomes 'sting' (sting is a kind of fraud).
'art' going within 'sting' is 'STARTING'.
(Other definitions for starting that I've seen before include "showing surprise" , "showing sudden alarm" , "Commencing" , "Disturbing" , "Rousing" .)
