Stolen goods; mars (6)
I believe the answer is:
spoils
This clue is a double definition.
'stolen goods' is the first definition.
(thesaurus)
'mars' is the second definition.
(I know this)
(Other definitions for spoils that I've seen before include "Damages" , "Ill-gotten gains" , "Booty" , "Plunder, benefits to victor" , "Mars - plunder" .)
