End of story read out (4)
I believe the answer is:
tail
'end' is the definition.
(I know that tail is a type of end)
'story read out' is the wordplay.
'story' becomes 'tale' (synonyms).
'read out' shows a homophone (sound like).
'tale' is a homophone of 'TAIL'.
'of' acts as a link.
(Other definitions for tail that I've seen before include "Elongated posterior part of an animal" , "that can be cast by a lizard" , "Follow - rear part of aeroplane" , "bum" , "Follow (a suspect)" .)
