End of the story we hear (4)
I believe the answer is:
tail
'end' is the definition.
(tail is a kind of end)
'the story we hear' is the wordplay.
'the story' becomes 'tale' (synonyms).
'we hear' indicates a 'sounds like' (homophone) clue.
'tale' sounds like 'TAIL'.
'of' is the link.
(Other definitions for tail that I've seen before include "that can be cast by a lizard" , "Follow - train" , "Follow furtively like private detective" , "weaker batsmen" , "Elongated posterior part of an animal" .)
