The Reef by Edith Wharton

Down the avenue there came to them, with the opening of the door, the voice of Owen's motor. It was the signal which had interrupted their first talk, and again, instinctively, they drew apart at the sound. Without a word Darrow turned back into the room, while Sophy Viner went down the steps and walked back alone toward the court.

At luncheon the presence of the surgeon, and the non-appearance of Madame de Chantelle -- who had excused herself on the plea of a headache -- combined to shift the conversational centre of gravity; and Darrow, under shelter of the necessarily impersonal talk, had time to adjust his disguise and to perceive that the others were engaged in the same re-arrangement. It was the first time that he had seen young Leath and Sophy Viner together since he had learned of their engagement; but neither revealed more emotion than befitted the occasion. It was evident that Owen was deeply under the girl's charm, and that at the least sign from her his bliss would have broken bounds; but her reticence was justified by the tacitly recognized fact of Madame de Chantelle's disapproval. This also visibly weighed on Anna's mind, making her manner to Sophy, if no less kind, yet a trifle more constrained than if the moment of final understanding had been reached.
