Poe's a weird storyteller (5)
I believe the answer is:
aesop
'storyteller' is the definition.
(Aesop is an example)
'poe's a weird' is the wordplay.
'weird' indicates an anagram.
'poes'+'a'='poesa'
'poesa' is an anagram of 'AESOP'.
(Other definitions for aesop that I've seen before include "A classical fable teller" , "Ancient Greek fabulist" , "fabulous figure?" , "classic author" , "A pose of famed fable teller" .)
