A play written in prison and a previously unpublished screenplay by Jean Genet published by Gallimard. Héliogabale, a drama in four acts never produced and thought to be lost, as well as the screenplay for Mademoiselle, adapted for the cinema by British director Tony Richardson in 1966.

The play was essentially written in Fresnes prison in 1942, at the same time as his first novel, Notre-Dame des Fleurs. Jean Cocteau read it too, but Genet never managed to find a publisher for him.
