“Keeping now steadily in mind the points to which I have drawn your attention — that peculiar voice, that unusual agility, and that startling absence of motive in a murder so singularly atrocious as this — let us glance at the butchery itself.  Here is a woman strangled to death by manual strength, and thrust up a chimney, head downward.  Ordinary assassins employ no such modes of murder as this.  Least of all, do they thus dispose of the murdered.  In the manner of thrusting the corpse up the chimney, you will admit that there was something excessively outré — something altogether irreconcilable with our common notions of human action, even when we suppose the actors the most depraved of men.  Think, too, how great must have been that strength which could have thrust the body up such an aperture so forcibly that the united vigor of several persons was found barely sufficient to drag it down!

“Turn, now, to other indications of the employment of a vigor most marvellous.  On the hearth were thick tresses — very thick tresses — of grey human hair.  These had been torn out by the roots.  You are aware of the great force necessary in tearing thus from the head even twenty or thirty hairs together.  You saw the locks in question as well as myself.  Their roots (a hideous sight!) were clotted with fragments of the flesh of the scalp — sure token of the prodigious power which had been exerted in uprooting perhaps half a million of hairs at a time.  The throat of the old lady was not merely cut, but the head absolutely severed from the body:  the instrument was a mere razor.  I wish you also to look at the brutal ferocity of these deeds.  Of the bruises upon the body of Madame L’Espanaye I do not speak.  Monsieur Dumas, and his worthy coadjutor Monsieur Etienne, have pronounced that they were inflicted by some obtuse instrument; and so far these gentlemen are very correct.  The obtuse instrument was clearly the stone pavement in the yard, upon which the victim had fallen from the window which looked in upon the bed.  This idea, however simple it may now seem, escaped the police for the same reason that the breadth of the shutters escaped them — because, by the affair of the nails, their perceptions had been hermetically sealed against the possibility of the windows having ever been opened at all.

“If now, in addition to all these things, you have properly reflected upon the odd disorder of the chamber, we have gone so far as to combine the ideas of an agility astounding, a strength superhuman, a ferocity brutal, a butchery without motive, a grotesquerie in horror absolutely alien from humanity, and a voice foreign in tone to the ears of men of many nations, and devoid of all distinct or intelligible syllabification.  What result, then, has ensued?  What impression have I made upon your fancy?”

I felt a creeping of the flesh as Dupin asked me the question.  “A madman,” I said, “has done this deed — some raving maniac, escaped from a neighboring Maison de Santé.”
