So Strether changes sides and loses all hopes of marrying Mrs. Newsome. Paris is winning--and then he catches sight of something new. Is not Chad, as regards any fineness in him, played out? Is not Chad's Paris after all just a place for a spree? This fear is confirmed. He goes for a solitary country walk, and at the end of the day he comes across Chad and Mme. de Vionnet. They are in a boat, they pretend not to see him, because their relation is at bottom an ordinary liaison, and they are ashamed. They were hoping for a secret week-end at an inn while their passion survived; for it will not survive, Chad will tire of the exquisite Frenchwoman, she is part of his fling; he will go back to his mother and make the little domestic article and marry Mamie. They know all this, and it is revealed to Strether though they try to hide it; they lie, they are vulgar--even Mme. de Vionnet, even her pathos, once so exquisite, is stained with commonness. It was like a chill in the air to him, it was almost appalling, that a creature so fine could be, by mysterious forces, a creature so exploited. For, at the end of all things, they _were_ mysterious; she had but made Chad what he was--so why could she think she had made him infinite? She had made him better, she had made him best, she had made him anything one would; but it came to our friend with supreme queerness that he was none the less only Chad. The work, however admirable, was nevertheless of the strict human order, and in short it was marvellous that the companion of mere earthly joys, of comforts, aberrations--however one classed them--within the common experience, should be so transcendency prized. She was older for him tonight, visibly less exempt from the touch of time; but she was as much as ever the finest and subtlest creature, the happiest apparition, it had been given him, in all his years, to meet; and yet he could see her there as vulgarly troubled, in very truth, as a maidservant crying for a young man. The only thing was that she judged herself as the maidservant wouldn't; the weakness of which wisdom too, the dishonour of which judgment, seemed but to sink her lower. So Strether loses them too. As he says: "I have lost everything--it is my only logic." It is not that they have gone back. It is that he has gone on. The Paris they revealed to him--he could reveal it to them now, if they had eyes to see, for it is something finer than they could ever notice for themselves, and his imagination has more spiritual value than their youth. The pattern of the hour-glass is complete; he and Chad have changed places, with more subtle steps than Thais and Paphnuce, and the light in the clouds proceeds not from the well-lit Alexandria, but from the jewel which "twinkled and trembled and melted together, and what seemed all surface one moment seemed all depth the next."
