The novel traces the domestic and creative life of Ferdinand Prestal, a modest railway clerk who cultivates a private writing habit and grows increasingly ambitious, and his wife Marthe, who balances household duties with compassionate work at a shelter for unmarried mothers. Through closely observed scenes of their marriage, parenting and the editing collaboration between spouses, the narrative contrasts literary aspiration and vanity with the quiet endurance of care. It depicts marginalized women with stark empathy, explores how ambition reshapes intimacy and moral judgment, and uses realistic detail to examine social vulnerability and the costs of self-absorption.
