The third book in Louis Couperus' Books of the Small Souls quartet. The Twilight of the Souls begins some months after the conclusion of The Later Life. Constance Van der Welcke and her husband Henri have settled down to a quieter life in the Hague, sister Bertha and her daughter Marianne have moved to the country, and Mama Van Lowe's Sunday evenings are no longer the gatherings of the whole family they once were. But the family's troubles are far from over. The story shifts to the trials and tribulations of Constance's brothers, Gerrit and Ernst, and Bertha's son and daughter, Henri and Emilie, who have fled together to Paris. - Summary by Phil Benson
