At length it grew to be noon of the appointed day. Nothing had transpired; all our labor was idle. I felt, nevertheless, more buoyant than usual,--whether because I was now to put my fate to the test, or that today was the one of which my black-browed man had spoken, and I therefore entertained a presentiment of good-fortune, I cannot say. But when, in unexceptionable toilet, I stood on Mme. de St. Cyr's steps, my heart sunk. G. was doubtless already within, and I thought of the _marchand des armures'_ exclamation, "Queen of Heaven, Monsieur! how shall I meet him!" I was plunged at once into the profoundest gloom. Why had I undertaken the business at all? This interference, this good-humor, this readiness to oblige,--it would ruin me yet! I forswore it, as Falstaff forswore honor. Why needed I to meddle in the _mêlée?_ Why--But I was no catechumen. Questions were useless now. My emotions are not chronicled on my face, I flatter myself; and with my usual repose I saluted our hostess. Greeting G. without any allusion to the diamond, the absence of which allusion he received as a point of etiquette, I was conversing with Mrs. Leigh, when the Baron Stahl was announced. I turned to look at his Excellency. A glance electrified me. There was my dark-browed man of the midnight streets. It must, then, have been concerning the diamond that I had heard him speak. His countenance, his eager, glittering eye, told that today was as eventful to him as to me. If he were here, I could well afford to be. As he addressed me in English, my certainty was confirmed; and the instant in which I observed the ring, gaudy and coarse, upon his finger, made confirmation doubly sure. I own I was surprised that anything could induce the Baron to wear such an ornament. Here he was actually risking his reputation as a man of taste, as an exquisite, a leader of _haut ton_, a gentleman, by the detestable vulgarity of this ring. But why do I speak so of the trinket? Do I not owe it a thrill of as fine joy as I ever knew? Faith! it was not unfamiliar to me. It had been a daily sight for years. In meeting the Baron Stahl I had found the diamond. The Baron Stahl was, then, the thief? Not at all. My valet, as of course you have been all along aware, was the thief.
