Swindle or fraud (5)
I believe the answer is:
sting
I believe this is a double definition.
'swindle' is the first definition.
(I know that sting is a type of swindle)
'fraud' is the second definition.
(I know that sting is a type of cheat)
(Other definitions for sting that I've seen before include "Goad" , "viz. Gordon Sumner" , "Bee's weapon" , "con trick" , "Sudden pain - swindle" .)
