It fully came up for them then, by means of their talking of everything _but_ Chad, that Mamie, unlike Sarah, unlike Jim, knew perfectly what had become of him. It fully came up that she had taken to the last fraction of an inch the measure of the change in him, and that she wanted Strether to know what a secret she proposed to make of it. They talked most conveniently—as if they had had no chance yet—about Woollett; and that had virtually the effect of their keeping the secret more close. The hour took on for Strether, little by little, a queer sad sweetness of quality, he had such a revulsion in Mamie’s favour and on behalf of her social value as might have come from remorse at some early injustice. She made him, as under the breath of some vague western whiff, homesick and freshly restless; he could really for the time have fancied himself stranded with her on a far shore, during an ominous calm, in a quaint community of shipwreck. Their little interview was like a picnic on a coral strand; they passed each other, with melancholy smiles and looks sufficiently allusive, such cupfuls of water as they had saved. Especially sharp in Strether meanwhile was the conviction that his companion really knew, as we have hinted, where she had come out. It was at a very particular place—only _that_ she would never tell him; it would be above all what he should have to puzzle for himself. This was what he hoped for, because his interest in the girl wouldn’t be complete without it. No more would the appreciation to which she was entitled—so assured was he that the more he saw of her process the more he should see of her pride. She saw, herself, everything; but she knew what she didn’t want, and that it was that had helped her. What didn’t she want?—there was a pleasure lost for her old friend in not yet knowing, as there would doubtless be a thrill in getting a glimpse. Gently and sociably she kept that dark to him, and it was as if she soothed and beguiled him in other ways to make up for it. She came out with her impression of Madame de Vionnet—of whom she had “heard so much”; she came out with her impression of Jeanne, whom she had been “dying to see”: she brought it out with a blandness by which her auditor was really stirred that she had been with Sarah early that very afternoon, and after dreadful delays caused by all sorts of things, mainly, eternally, by the purchase of clothes—clothes that unfortunately wouldn’t be themselves eternal—to call in the Rue de Bellechasse.
