Fur trade's arranged by this dodgy dealer (9)
I believe the answer is:
fraudster
'this dodgy dealer' is the definition.
(a fraudster might do dodgy deals)
'fur trade's arranged' is the wordplay.
'arranged' indicates anagramming the letters (letters rearranged).
'fur'+'trades'='furtrades'
'furtrades' is an anagram of 'FRAUDSTER'.
'by' acts as a link.
(Other definitions for fraudster that I've seen before include "Charlatan" , "28 [CHEAT]" , "Con man" , "he'll take you for a ride" , "I'll take you for a ride" .)
