Storyteller found wader on the way back (4)
I believe the answer is:
liar
'storyteller' is the definition.
(thesaurus)
'wader on the way back' is the wordplay.
'wader' becomes 'rail' (rail is a kind of wader).
'on the way back' says the letters should be written in reverse.
'rail' back-to-front is 'LIAR'.
'found' acts as a link.
(Other definitions for liar that I've seen before include "Fibber" , "Bearer of false witness" , "Perjuror" , "Storyteller" , "One supplying pork pies" .)
