They had just passed the door when I emerged, and they receded, at a slow pace and with a kind of confidential nearness, down the long avenue of the lobby. Her head was always high and her husband's always low, so that I couldn't be sure--it might have been only my fancy--that the contrast of this habit was more marked in them than usual. If I had known nothing about them I should have just unimaginatively said that talk was all on one side and attention all on the other. I, of course, for that matter, _did_ know nothing about them; yet I recall how it came to me, as my extemporised shrewdness hung in their rear, that I mustn't think anything too grossly simple of what might be taking place between them. My position was, in spite of myself, that of my having mastered enough possibilities to choose from. If one of these might be--for her face, in spite of the backward cock of her head, was turned to him--that she was looking her time of life straight _at_ him and yet making love to him with it as hard as ever she could, so another was that he had been already so thoroughly got back into hand that she had no need of asking favours, that she was more splendid than ever, and that, the same poor Briss as before his brief adventure, he was only feeling afresh in his soul, as a response to her, the gush of the sacred fount. Presumptous choice as to these alternatives failed, on my part, in time, let me say, to flower; it rose before me in time that, whatever might be, for the exposed instant, the deep note of their encounter, only one thing concerned me in it: its being wholly their own business. So for that I liberally let it go, passing into the corridor, but proceeding in the opposite sense and aiming at an issue which I judged I should reach before they would turn in their walk. I had not, however, reached it before I caught the closing of the door furthest from me; at the sound of which I looked about to find the Brissendens gone. They had not remained for another turn, but had taken their course, evidently, back to the principal drawing-room, where, no less presumably, the procession of the ladies bedward was even then forming. Mrs. Briss would fall straight into it, and I _had_ accordingly lost her. I hated to appear to pursue her, late in the day as it may appear to affirm that I put my dignity before my curiosity.
