Story end is heard (4)
I believe the answer is:
tale
'story' is the definition.
(I know that story can be written as tale)
'end is heard' is the wordplay.
'end' becomes 'tail' (tail is a kind of end).
'is heard' shows a homophone (sound like).
'tail' sounds like 'TALE'.
(Other definitions for tale that I've seen before include "Shakespeare play: 'The Winter's . . . .'" , "Narrative - fabrication" , "relation" , "Report" , "Anecdotal narrative" .)
