Edith Wharton''s "Madame de Treymes" is a remarkable example of the form. It is the story of the tactical defeat but moral victory of an honest and upstanding American in his struggle to win a wife from a tightly united but feudally minded French aristocratic family. He loses, but they cheat. . . . In a masterpiece of brevity, Wharton dramatizes the contrast between the two opposing forces: the simple and proper old brownstone New York, low in style but high in principle, and the achingly beautiful but decadent Saint-Germain district of Paris. The issue is seamlessly joined.
