When, in an article entitled “The Murders in the Rue Morgue,” I endeavored, about a year ago, to depict some very remarkable features in the mental character of my friend, the Chevalier C. Auguste Dupin, it did not occur to me that I should ever resume the subject. This depicting of character constituted my design; and this design was thoroughly fulfilled in the wild train of circumstances brought to instance Dupin’s idiosyncrasy. I might have adduced other examples, but I should have proven no more. Late events, however, in their surprising development, have startled me into some farther details, which will carry with them the air of extorted confession. Hearing what I have lately heard, it would be indeed strange should I remain silent in regard to what I both heard and saw so long ago. Upon the winding up of the tragedy involved in the deaths of Madame L’Espanaye and her daughter, the Chevalier dismissed the affair at once from his attention, and relapsed into his old habits of moody reverie. Prone, at all times, to abstraction, I readily fell in with his humor; and, continuing to occupy our chambers in the Faubourg Saint Germain, we gave the Future to the winds, and slumbered tranquilly in the Present, weaving the dull world around us into dreams. But these dreams were not altogether uninterrupted. It may readily be supposed that the part played by my friend, in the drama at the Rue Morgue, had not failed of its impression upon the fancies of the Parisian police. With its emissaries, the name of Dupin had grown into a household word. The simple character of those inductions by which he had disentangled the mystery never having been explained even to the Prefect, or to any other individual than myself, of course it is not surprising that the affair was regarded as little less than miraculous, or that the Chevalier’s analytical abilities acquired for him the credit of intuition. His frankness would have led him to disabuse every inquirer of such prejudice; but his indolent humor forbade all farther agitation of a topic whose interest to himself had long ceased. It thus happened that he found himself the cynosure of the political eyes; and the cases were not few in which attempt was made to engage his services at the Prefecture. One of the most remarkable instances was that of the murder of a young girl named Marie Rogêt.
