Turns up, from the start, Eliot and Frost got hold of graphic introduction produced by political exile
I believe the answer is:
emigre
'political exile' is the definition.
(I've seen this before)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for emigre that I've seen before include "he was driven out of the country" , "Citizen who has left native country" , "One in political exile" , "One living abroad for political reasons" , "One leaving their nation" .)
