Follow narrative on the radio? (4)
I believe the answer is:
tail
'follow' is the definition.
(both can mean to chase or pursue)
'narrative on the radio?' is the wordplay.
'narrative' becomes 'tale' (synonyms).
'on the radio?' shows a homophone (sound like) (I've seen 'on the radio' mean this).
'tale' sounds like 'TAIL'.
(Other definitions for tail that I've seen before include "Elongated posterior part of an animal" , "Comet's luminous trail" , "Follow (a suspect)" , "Queue" , "Dog - end" .)
