On the fourth day an unexpected event threw out his calculations. Summoned to town by the arrival in England of her husband’s mother, she left without giving Darrow the chance he had counted on, and he cursed himself for a dilatory blunderer. Still, his disappointment was tempered by the certainty of being with her again before she left for France; and they did in fact see each other in London. There, however, the atmosphere had changed with the conditions. He could not say that she avoided him, or even that she was a shade less glad to see him; but she was beset by family duties and, as he thought, a little too readily resigned to them. The Marquise de Chantelle, as Darrow soon perceived, had the same mild formidableness as the late Mr. Leath: a sort of insistent self-effacement before which every one about her gave way. It was perhaps the shadow of this lady’s presence--pervasive even during her actual brief eclipses--that subdued and silenced Mrs. Leath. The latter was, moreover, preoccupied about her stepson, who, soon after receiving his degree at Harvard, had been rescued from a stormy love-affair, and finally, after some months of troubled drifting, had yielded to his step-mother’s counsel and gone up to Oxford for a year of supplementary study. Thither Mrs. Leath went once or twice to visit him, and her remaining days were packed with family obligations: getting, as she phrased it, “frocks and governesses” for her little girl, who had been left in France, and having to devote the remaining hours to long shopping expeditions with her mother-in-law. Nevertheless, during her brief escapes from duty, Darrow had had time to feel her safe in the custody of his devotion, set apart for some inevitable hour; and the last evening, at the theatre, between the overshadowing Marquise and the unsuspicious Owen, they had had an almost decisive exchange of words.
