History of the Automobile,[1] and the French-English Automobile Dictionary in 1910.
In 1909, already a published author, Souvestre co-wrote, with his friend and assistant Allain, their first novel, Le Rour. Investigating Magistrate Germain Fuselier, later to become a recurring character in the Fantômas series, appears in this first novel.

Allain and Souvestre also jointly wrote the spy series Naz-en-l'air. After his death, Allain continued the Fantômas saga alone.
