I had not yet seen the cathedral of Notre Dame, and thither I drove. I spent an hour or more there; and then to the Conciergerie, the Palais de Justice, and the beautiful Sainte Chapelle. Still there remained some time to get rid of, and I strolled into the narrow streets adjoining the cathedral. I recollect seeing, in one of them, an old house with a mural inscription stating that it had been the residence of Canon Fulbert, the uncle of Abelard's Eloise. I don't know whether these curious old streets, in which I observed fragments of ancient Gothic churches fitted up as warehouses, are still extant. I lighted, among other dingy and eccentric shops, upon one that seemed that of a broker of all sorts of old decorations, armor, china, furniture. I entered the shop; it was dark, dusty, and low. The proprietor was busy scouring a piece of inlaid armor, and allowed me to poke about his shop, and examine the curious things accumulated there, just as I pleased. Gradually I made my way to the farther end of it, where there was but one window with many panes, each with a bull's eye in it, and in the dirtiest Possible state. When I reached this window, I turned about, and in a recess, standing at right angles with the side wall of the shop, was a large mirror in an old-fashioned dingy frame. Reflected in this I saw what in old houses I have heard termed an "alcove," in which, among lumber and various dusty articles hanging on the wall, there stood a table, at which three persons were seated, as it seemed to me, in earnest conversation. Two of these persons I instantly recognized; one was Colonel Gaillarde, the other was the Marquis d'Harmonville. The third, who was fiddling with a pen, was a lean, pale man, pitted with the small-pox, with lank black hair, and about as mean-looking a person as I had ever seen in my life. The Marquis looked up, and his glance was instantaneously followed by his two companions. For a moment I hesitated what to do. But it was plain that I was not recognized, as indeed I could hardly have been, the light from the window being behind me, and the portion of the shop immediately before me being very dark indeed. Perceiving this, I had presence of mind to affect being entirely engrossed by the objects before me, and strolled slowly down the shop again. I paused for a moment to hear whether I was followed, and was relieved when I heard no step. You may be sure I did not waste more time in that shop, where I had just made a discovery so curious and so unexpected. It was no business of mine to inquire what brought Colonel Gaillarde and the Marquis together, in so shabby and even dirty a place, or who the mean person, biting the feather end of his pen, might be. Such employments as the Marquis had accepted sometimes make strange bed-fellows.
