"The Boy Who Cried Wolf" author (5)
I believe the answer is:
aesop
'the boy who cried wolf author' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for aesop that I've seen before include "Greek storyteller" , "A classical fable teller" , "Fabulous man" , "A pose of famed fable teller" , "Ancient Greek author of moral tales" .)
