Mrs. Briss considered. "I don't quite see, do I? why, at this hour of the night, we should begin to retrace steps." "Simply because it's the hour of the night you've happened, in your generosity and your discretion, to choose. I'm struck, I confess," I declared with a still sharper conviction, "with the wonderful charm of it for our purpose." "And, pray, what do you call with such solemnity," she inquired, "our purpose?" I had fairly recovered at last--so far from being solemn--an appropriate gaiety. "I can only, with positiveness, answer for mine! That has remained all day the same--to get at the truth: not, that is, to relax my grasp of that tip of the tail of it which you so helped me this morning to fasten to. If you've ceased to _care_ to help me," I pursued, "that's a difference indeed. But why," I candidly, pleadingly asked, "_should_ you cease to care?" It was more and more of a comfort to feel her imprisoned in her inability really to explain her being there. To show herself as she was explained it only so far as she could express that; which was just the freedom she could least take. "What on earth is between us, anyhow," I insisted, "but our confounded interest? That's only quickened, for me, don't you see? by the charming way you've come round; and I don't see how it can logically be anything less than quickened for yourself. We're like the messengers and heralds in the tale of Cinderella, and I protest, I assure you, against any sacrifice of our dénoûment. We've still the glass shoe to fit." I took pleasure at the moment in my metaphor; but this was not the case, I soon enough perceived, with my companion. "How can I tell, please," she demanded, "what you consider you're talking about?" I smiled; it was so quite the question Ford Obert, in the smoking-room, had begun by putting me. I hadn't to take time to remind myself how I had dealt with _him_. "And you knew," I sighed, "so beautifully, you glowed over it so, this morning!" She continued to give me, in every way, her disconnection from this morning, so that I had only to proceed: "You've not availed yourself of this occasion to pretend to me that poor Mr. Long, as you call him, is, after all, the same limited person----" "That he always was, and that you, yesterday, so suddenly discovered him to have ceased to be?"--for with this she had waked up. But she was still thinking how she could turn it. "You see too much." "Oh, I know I do--ever so much too much. And much as I see, I express only half of it--so you may judge!" I laughed. "But what will you have? I see what I see, and this morning, for a good bit, you did me the honour to do the same. I returned, also, the compliment, didn't I? by seeing something of what _you_ saw. We put it, the whole thing, together, and we shook the bottle hard. I'm to take from you, after this," I wound up, "that what it contains is a perfectly colourless fluid?"
