Puppet or pawn (4)
I believe the answer is:
tool
I believe this clue is a double definition.
'puppet' is the first definition.
(I know that puppet can be written as tool)
'pawn' is the second definition.
(I've seen this in another clue)
(Other definitions for tool that I've seen before include "Instrument, implement" , "Person exploited" , "Gun" , "Weapon" , "Maybe saw" .)
