New-York, milieu du XIXe siècle. Catherine Sloper est une jeune fille sans grande beauté et à l’esprit simple, mais elle est l’unique héritière du docteur Sloper qui a acquis une fortune importante. Lors d'un bal, elle rencontre le beau Morris Townsend. Il la courtise, elle tombe amoureuse et jure de l'épouser... Mais tiendra-t-elle son engagement, contre l’avis de son père qui menace de la déshériter, et le jeune homme est-il vraiment sincère ? Amour, argent et faux-semblants ; Washington Square, publié en 1881, dresse le portrait d'une société figée à l’aube d’une ère nouvelle.
When timid and plain Catherine Sloper is courted by the dashing and determined Morris Townsend, her father, convinced that the young man is nothing more than a fortune-hunter, delivers an ultimatum: break off her engagement, or be stripped of her inheritance. Torn between her desire to win her father's love and approval and her passion for the only man who has ever declared his love for her, Catherine faces an agonising dilemma, and becomes all too aware of the restrictions that others seek to place on her freedom. James's masterly novel deftly interweaves the public and private faces of nineteenth-century New York society; it is also a deeply moving study of innocence destroyed.
