Guy de Cars is one of the most popular writers of post-war France. His heroines are young and charming, but their purity turns out to be unarmed against the dark sides of life in huge Paris. The dramatic nature of the narrative is achieved by the writer by combining an externally dynamic plot and internal psychological tension, the struggle of opposing forces: love and selflessness on the one hand and vice, turning into crime, on the other. But moral victory always belongs to the forces of good.
