Paris Police 1900

Paris, 1899. President Félix Faure has just died in the arms of his mistress. While the Republic is on the verge of explosion, Prefect Lépine is called back to business. At the same time, at the prefecture, Inspector Jouin was mobilized on a large-scale investigation to identify "the unknown person in the suitcase".

Inspector Jouin fells in love with Jeanne Chauvin, a young lawyer with a strong character, who could not practice but served as an assistant to Master Weidmann in the Jewish district of La Vilette. Jeanne decides to help him in the Berger case. For her part, Meg receives Madame Lépine, the prefects wife, at home, whose penchant for artificial paradises has not escaped Commissioner Puybaraud.

As more evidence appears against Sabran in the investigation into Josephines murder, Meg has fallen under his spell.

Prefect Lepine gets help from the anarchists while Guerin organises the riots planned for Rue Chabrol.
