Lady killer (9)
I believe the answer is:
murderess
This might be a double definition.
'lady' is the first definition.
The definition and answer can be both people as well as being singular nouns.
Perhaps they are linked in a way I don't understand?
'killer' is the second definition.
(I know that murderess is a type of liquidator)
Can you help me to learn more?
(Other definitions for murderess that I've seen before include "Lady killer?" , "Female killer" .)
