Dead estate agent (8)
I believe the answer is:
executor
This might be a double definition.
'dead estate' is the first definition.
Although both the answer and definition are singular nouns, I don't see how one could define the other.
'agent' is the second definition.

Can you help me to learn more?
(Other definitions for executor that I've seen before include "Administrator" , "Person who carries out the provisions of a will" , "One dealing with will" , "Person nominated to carry out the terms of a will" , "One is appointed to carry out the terms of a will" .)
