Killer getting rid of poet’s wife (6)
I believe the answer is:
hitman
'killer' is the definition.
(I know that hitman is a type of liquidator)
I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for hitman that I've seen before include "offer?" , "Hired gun" , "killer" , "Assassin" .)
