Either, then, he no longer had the same necessity for a dupe, or he no longer imagined I should become one. Yet neither of these suppositions was probable. It was not likely that he should grow suddenly honest, or suddenly rich: nor had I, on the other hand, given him any reason to suppose I was a jot more wary than any other individual he might have imposed upon. On the contrary, I had appeared to seek his acquaintance with an eagerness which said but little for my knowledge of the world. The more I reflected, the more I should have been puzzled, had I not connected his present backwardness with his acquaintance with the stranger, whom he termed Warburton. It is true, that I had no reason to suppose so: it was a conjecture wholly unsupported, and, indeed, against my better sense; yet, from some unanalysed associations, I could not divest myself of the supposition. "I will soon see," thought I; and wrapping myself in my cloak, for the day was bitterly cold, I bent my way to Thornton's lodgings. I could not explain to myself the deep interest I took in whatever was connected with (the so-called) Warburton, or whatever promised to discover more clearly any particulars respecting him. His behaviour in the gambling house; his conversation with the woman in the Jardin des Plantes; and the singular circumstance, that a man of so very aristocratic an appearance, should be connected with Thornton, and only seen in such low scenes, and with such low society, would not have been sufficient so strongly to occupy my mind, had it not been for certain dim recollections, and undefinable associations, that his appearance when present, and my thoughts of him when absent, perpetually recalled. As, engrossed with meditations of this nature, I was passing over the Pont Neuf, I perceived the man Warburton had so earnestly watched in the gambling house, and whom I identified with the "Tyrrell," who had formed the subject of conversation in the Jardin des Plantes, pass slowly before me. There was an appearance of great exhaustion in his swarthy and strongly marked countenance. He walked carelessly on, neither looking to the right nor the left, with that air of thought and abstraction which I have remarked as common to all men in the habit of indulging any engrossing and exciting passion.
