Robbery of some people in a car? (5)
I believe the answer is:
caper
'robbery' is the definition.
(caper is a kind of robbery)
'some people in a car?' is the wordplay.
'some people' becomes 'pe' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'in' is an insertion indicator.
'pe' put inside 'car' is 'CAPER'.
'of' is the link.
Can you help me to learn more?
(Other definitions for caper that I've seen before include "game" , "Recap about prank" , "jump around?" , "Frolic - bud used in cooking" , "One likely to get pickled" .)
