Show into Poe's house? (5)
I believe the answer is:
usher
I believe this clue is a double definition.
'show' is the first definition.
(I know that show can be written as usher)
'poe's house?' is the second definition.
(I've seen this in another clue)
'into' is the link.
(Other definitions for usher that I've seen before include "One puts you in your place" , "Introduce" , "Doorkeeper; shower to seat" , "Doorkeeper in parliament or 29 down" , "Person showing one to a seat" .)
