L'Assommoir (1877), the seventh novel in the Les Rougon-Macquart cycle, is a poignant story of a woman's struggle for happiness in working-class Paris. At the heart of this narrative is Gervaise, who begins with the dream of a better life by starting her own laundry business, achieving success for a while. However, her husband's addiction to the local drinking spot, the Assommoir, leads them down a path of poverty and despair.

This novel not only became a contemporary bestseller but also sparked a fierce debate about the scope of modern literature. It outraged conservative critics with its unflinching portrayal of the harsh realities faced by the working poor, capturing both the brutality and the pathos of its characters' lives.
