Shots not unique in assassination (7)
I believe the answer is:
doubles
This could be a double definition.
'shots' is the first definition.
The definition and answer can be both acts as well as being plural nouns.
Maybe there's an association between them I don't understand?
'unique in assassination' is the second definition.
The definition and answer can be both acts as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'not' is the link.
Can you help me to learn more?
(Other definitions for doubles that I've seen before include "Like Carton and Darnay" , "sort of game" , "match in court" , "Tennis match for four players" , "Made twice as much" .)
