“Le Tribunal,” he replied, “has not entered, I fear, into the unusual horror of the thing. But we will not revert to the idle opinions of this print. It appears to me that this mystery is considered insoluble, for the very reason which should cause it to be regarded as easy of solution—I mean for the _outré_ character of its features. The police are confounded by the seeming absence of motive—not for the murder itself—but for the atrocity of the murder. They are puzzled by the seeming impossibility of reconciling the voices heard in contention, with the facts that no one was discovered up stairs but the assassinated Mademoiselle L’Espanaye, and that there were no means of egress without the notice of the party ascending. The wild disorder of the room; the corpse thrust with the head downward up the chimney; the frightful mutilation of the body of the old lady; these considerations, with those just mentioned, and others which I need not mention, have sufficed to paralyze the powers, by putting completely at fault the boasted acumen, of the government agents. They have fallen into the gross but common error of confounding the unusual with the abstruse. But it is by these deviations from the plane of the ordinary, that reason feels its way, if at all, in its search after the true. In investigations such as we are now pursuing, it should not be so much asked ‘what has occurred,’ as ‘what has occurred which has never occurred before.’ In fact, the facility with which I shall arrive, or have arrived, at the solution of this mystery, is in exact ratio with its apparent insolubility in the eyes of the police.” I stared at the speaker in mute astonishment. He continued. “I am now awaiting,” continued he, looking toward the door of our apartment—“I am now awaiting a person who, although perhaps not the perpetrator of these butcheries, must have been in some measure implicated in their perpetration. Of the worst portion of the crimes committed it is probable that he is innocent. I hope that I am right in this supposition; for upon it I build my expectation of reading the entire riddle. I look for the man here—in this room—every moment. It is true that he may not arrive; but the probability is that he will. Should he come, it will be necessary to detain him. Here are pistols; and we both know how to use them when occasion demands their use.” I took the pistols, scarcely knowing what I did, or believing what I heard, while Dupin went on, very much as if in a soliloquy. I have already spoken of his abstract manner at such times. His discourse was addressed to myself; but his voice, although by no means loud, had that intonation which is commonly employed in speaking to some one at a great distance. His eyes, vacant in expression, regarded only the wall.
