"The Flies” playwright (6)
I believe the answer is:
sartre
'the flies playwright' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for sartre that I've seen before include "French existentialist philosopher and writer" , "French philosopher, 1905-80" , "Jean-Paul --, French writer and philosopher" , "Jean-Paul -, French philosopher/author" , "Jean Paul -, French author" .)
