"J'Accuse . . ." writer (4)
I believe the answer is:
zola
'j'accuse writer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for zola that I've seen before include "Emile --, French writer" , "Emile -, Fr. novelist" , "European writer" , "French novelist, defender of Dreyfus, d. 1902" , "French author of Germinal" .)
