"The Three Cities Trilogy Complete: Lourdes, Rome and Paris" by Émile Zola follows the beloved 'hero, Father Pierre Froment, who serves as the conductor for the three novels, Lourdes, Rome and Paris. In each of these city settings, Zola questions the role of religion in modern society, but also draws comparisons between a radiant bourgeoisie and the miserable working-class world that was present in Europe and continues to this day.
