Someone who got what was coming to them? (9)
I believe the answer is:
inheritor
'someone' is the definition.
(inheritor is a kind of someone)
'got what was coming to them?' is the wordplay.
I cannot really understand how this works, but
'to' is found in the answer.
This may be the basis of the clue (or it may be nonsense).
'who' is the link.
Can you help me to learn more?
(Other definitions for inheritor that I've seen before include "Successor" , "Heir" , "Beneficiary under will" , "He comes into estate" , "One mentioned in will" .)
