Deception involving money producing stink (5)
I believe the answer is:
smell
'stink' is the definition.
(I know that stink can be written as smell)
'deception involving money' is the wordplay.
'deception' becomes 'sell' (old-fashioned term for a hoax or con).
'involving' is an insertion indicator.
'money' becomes 'm' (abbreviation used in economics).
'sell' placed around 'm' is 'SMELL'.
'producing' is the link.
(Other definitions for smell that I've seen before include "Scent" , "Sniff" , "stink" , "Hum" , "Perceive through the nose" .)
