Ilsa, an original 1938 copy of
Bagatelles pour un massacre lies here in my library together with
Voyage au bout de la nuit but I hesitate to read them as Céline's writing is famous for its use of "argot" making it hard to understand even for French people... I think it's worth trying reading it in French though...
In my turn I recommend:
Confessions of a Mask by Yukio Mishima
