Artist to trick strangely true storyteller (9)
I believe the answer is:
raconteur
'storyteller' is the definition.
(raconteur is a kind of storyteller)
'artist to trick strangely true' is the wordplay.
'artist' becomes 'RA' (Royal Academician, member of Royal Academy of Arts).
'to trick' becomes 'con' (I've seen this before).
'strangely' is an anagram indicator.
'true' anagrammed gives 'teur'.
'ra'+'con'+'teur'='RACONTEUR'
(Other definitions for raconteur that I've seen before include "He's good at telling stories" , "A skilled storyteller, very entertaining" , "After-dinner speaker, maybe" , "Teller of anecdotes, Frenchstyle" , "Teller of anecdote" .)
