Works overseas, clutching empty purse (6)
I believe the answer is:
opuses
'works' is the definition.
(an opus is a creative work)
'overseas clutching empty purse' is the wordplay.
'overseas' becomes 'os' (abbreviation).
'clutching' means one lot of letters goes inside another.
'empty' suggests removing the centre.
'purse' with its middle taken out is 'puse'.
'os' enclosing 'puse' is 'OPUSES'.
(Other definitions for opuses that I've seen before include "pieces of music" , "Musical works" .)
