Poe surname (5)
I believe the answer is:
usher
'poe surname' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for usher that I've seen before include "Show (in or out); doorkeeper" , "One who should lead the way" , "One who shows people to seats" , "Doorman or seat guide" , "Cinema or wedding official" .)
