In the Shadow of the Master (23 page)

“I know not,” continued Dupin, “what impression I may have made, so far, upon your own understanding; but I do not hesitate to say that legitimate deductions even from this portion of the testimony-the portion respecting the gruff and shrill voices-are in themselves sufficient to engender a suspicion which should give direction to all farther progress in the investigation of the mystery. I said ‘legitimate deductions’; but my meaning is not thus fully expressed. I designed to imply that the deductions are the
sole
proper ones, and that the suspicion arises
inevitably
from them as the single result. What the suspicion is, however, I will not say just yet. I merely wish you to bear in mind that, with myself, it was sufficiently forcible to give a definite form-a certain tendency-to my inquiries in the chamber.

“Let us now transport ourselves, in fancy, to this chamber. What shall we first seek here? The means of egress employed by the murderers. It is not too much to say that neither of us believe in praeternatural events. Madame and Mademoiselle L’Espanaye were not destroyed by spirits. The doers of the deed were material and escaped materially. Then how? Fortunately there is but one mode of reasoning upon the point, and that mode
must
lead us to a definite decision. Let us examine, each by each, the possible means of egress. It is clear that the assassins were in the room where Mademoiselle L’Espanaye was found, or at least in the room adjoining, when the party ascended the stairs. It is, then, only from these two apartments that we have to seek issues. The police have laid bare the floors, the ceilings, and the masonry of the walls, in every direction. No
secret
issues could have escaped their vigilance. But, not trusting to
their
eyes, I examined with my own. There were, then,
no
secret issues. Both doors leading from the rooms into the passage were securely locked, with the keys inside. Let us turn to the chimneys. These, although of ordinary width for some eight or ten feet above the hearths, will not admit, throughout their extent, the body of a large cat. The impossibility of egress, by means already stated, being thus absolute, we are reduced to the windows. Through those of the front room no one could have escaped without notice from the crowd in the street. The murderers
must
have passed, then, through those of the back room. Now, brought to this conclusion in so unequivocal a manner as we are, it is not our part, as reasoners, to reject it on account of apparent impossibilities. It is only left for us to prove that these apparent ‘impossibilities’ are, in reality, not such.

“There are two windows in the chamber. One of them is unobstructed by furniture, and is wholly visible. The lower portion of the other is hidden from view by the head of the unwieldy bedstead which is thrust close up against it. The former was found securely fastened from within. It resisted the utmost force of those who endeavored to raise it. A large gimlet-hole had been pierced in its frame to the left, and a very stout nail was found fitted therein, nearly to the head. Upon examining the other window, a similar nail was seen similarly fitted in it; and a vigorous attempt to raise this sash failed also. The police were now entirely satisfied that egress had not been in these directions. And,
therefore,
it was thought a matter of supererogation to withdraw the nails and open the windows.

“My own examination was somewhat more particular, and was so for the reason I have just given-because here it was, I knew, that all apparent impossibilities
must
be proved to be not such in reality.

“I proceeded to think thus-
a posteriori
. The murderers
did
escape from one of these windows. This being so, they could not have refastened the sashes from the inside, as they were found fastened;- the consideration which put a stop, through its obviousness, to the scrutiny of the police in this quarter. Yet the sashes
were
fastened. They
must,
then, have the power of fastening themselves. There was no escape from this conclusion. I stepped to the unobstructed casement, withdrew the nail with some difficulty, and attempted to raise the sash. It resisted all my efforts, as I had anticipated. A concealed spring must, I now know, exist; and this corroboration of my idea convinced me that my premises, at least, were correct, however mysterious still appeared the circumstances attending the nails. A careful search soon brought to light the hidden spring. I pressed it, and, satisfied with the discovery, forbore to upraise the sash.

“I now replaced the nail and regarded it attentively. A person passing out through this window might have reclosed it, and the spring would have caught-but the nail could not have been replaced. The conclusion was plain, and again narrowed in the field of my investigations. The assassins
must
have escaped through the other window. Supposing, then, the springs upon each sash to be the same, as was probable, there
must
be found a difference between the nails, or at least between the modes of their fixture. Getting upon the sacking of the bedstead, I looked over the head-board minutely at the second casement. Passing my hand down behind the board, I readily discovered and pressed the spring, which was, as I had supposed, identical in character with its neighbor. I now looked at the nail. It was as stout as the other, and apparently fitted in the same manner-driven in nearly up to the head.

“You will say that I was puzzled; but, if you think so, you must have misunderstood the nature of the inductions. To use a sporting phrase, I had not been once ‘at fault.’ The scent had never for an instant been lost. There was no flaw in any link of the chain. I had traced the secret to its ultimate result,-and that result was
the nail
. It had, I say, in every respect, the appearance of its fellow in the other window; but this fact was an absolute nullity (conclusive as it might seem to be) when compared with the consideration that here, at this point, terminated the clue. ‘There
must
be something wrong,’ I said, ‘about the nail.’ I touched it; and the head, with about a quarter of an inch of the shank, came off in my fingers. The rest of the shank was in the gimlet-hole where it had been broken off. The fracture was an old one (for its edges were incrusted with rust), and had apparently been accomplished by the blow of a hammer, which had partially imbedded, in the top of the bottom sash, the head portion of the nail. I now carefully replaced this head portion in the indentation whence I had taken it, and the resemblance to a perfect nail was complete-the fissure was invisible. Pressing the spring, I gently raised the sash for a few inches; the head went up with it, remaining firm in its bed. I closed the window, and the semblance of the whole nail was again perfect.

“The riddle, so far, was now unriddled. The assassin had escaped through the window which looked upon the bed. Dropping of its own accord upon his exit (or perhaps purposely closed), it had become fastened by the spring; and it was the retention of this spring which had been mistaken by the police for that of the nail,- farther inquiry being thus considered unnecessary.

“The next question is that of the mode of descent. Upon this point I had been satisfied in my walk with you around the building. About five feet and a half from the casement in question there runs a lightning-rod. From this rod it would have been impossible for any one to reach the window itself, to say nothing of entering it. I observed, however, that the shutters of the fourth story were of the peculiar kind called by Parisian carpenters
ferrades
-a kind rarely employed at the present day, but frequently seen upon very old mansions at Lyons and Bordeaux. They are in the form of an ordinary door, (a single, not a folding door), except that the lower half is latticed or worked in open trellis-thus affording an excellent hold for the hands. In the present instance these shutters are fully three feet and a half broad. When we saw them from the rear of the house, they were both about half open-that is to say, they stood off at right angles from the wall. It is probable that the police, as well as myself, examined the back of the tenement; but, if so, in looking at these
ferrades
in the line of their breadth (as they must have done), they did not perceive this great breadth itself, or, at all events, failed to take it into due consideration. In fact, having once satisfied themselves that no egress could have been made in this quarter, they would naturally bestow here a very cursory examination. It was clear to me, however, that the shutter belonging to the window at the head of the bed, would, if swung fully back to the wall, reach to within two feet of the lightning-rod. It was also evident that, by exertion of a very unusual degree of activity and courage, an entrance into the window, from the rod, might have been thus effected. By reaching to the distance of two feet and a half (we now suppose the shutter open to its whole extent) a robber might have taken a firm grasp upon the trellis-work. Letting go, then, his hold upon the rod, placing his feet securely against the wall, and springing boldly from it, he might have swung the shutter so as to close it, and, if we imagine the window open at the time, might even have swung himself into the room.

“I wish you to bear especially in mind that I have spoken of a
very
unusual degree of activity as requisite to success in so hazardous and so difficult a feat. It is my design to show you first, that the thing might possibly have been accomplished:-but, secondly and
chiefly,
I wish to impress upon your understanding the
very extraordinary
- the almost praeternatural character of that agility which could have accomplished it.

“You will say, no doubt, using the language of the law, that to make out my case, I should rather undervalue, than insist upon a full estimation of the activity required in this matter. This may be the practice in law, but it is not the usage of reason. My ultimate object is only the truth. My immediate purpose is to lead you to place in juxtaposition, that
very unusual
activity of which I have just spoken with that
very peculiar
shrill (or harsh) and
unequal
voice, about whose nationality no two persons could be found to agree, and in whose utterance no syllabification could be detected.”

At these words a vague and half-formed conception of the meaning of Dupin flitted over my mind. I seemed to be upon the verge of comprehension without power to comprehend-as men, at times, find themselves upon the brink of remembrance, without being able, in the end, to remember. My friend went on with his discourse.

“You will see,” he said, “that I have shifted the question from the mode of egress to that of ingress. It was my design to convey the idea that both were effected in the same manner, at the same point. Let us now revert to the interior of the room. Let us survey the appearances here. The drawers of the bureau, it is said, had been rifled, although many articles of apparel still remained within them. The conclusion here is absurd. It is a mere guess-a very silly one-and no more. How are we to know that the articles found in the drawers were not all these drawers had originally contained? Madame L’Espanaye and her daughter lived an exceedingly retired life-saw no company-seldom went out-had little use for numerous changes of habiliment. Those found were at least of as good quality as any likely to be possessed by these ladies. If a thief had taken any, why did he not take the best-why did he not take all? In a word, why did he abandon four thousand francs in gold to encumber himself with a bundle of linen? The gold
was
abandoned. Nearly the whole sum mentioned by Monsieur Mignaud, the banker, was discovered, in bags, upon the floor. I wish you therefore, to discard from your thoughts the blundering idea of
motive,
engendered in the brains of the police by that portion of the evidence which speaks of money delivered at the door of the house. Coincidences ten times as remarkable as this (the delivery of the money, and murder committed within three days upon the party receiving it), happen to all of us every hour of our lives, without attracting even momentary notice. Coincidences, in general, are great stumbling-blocks in the way of that class of thinkers who have been educated to know nothing of the theory of probabilities-that theory to which the most glorious objects of human research are indebted for the most glorious of illustration. In the present instance, had the gold been gone, the fact of its delivery three days before would have formed something more than a coincidence. It would have been corroborative of this idea of motive. But, under the real circumstances of the case, if we are to suppose gold the motive of this outrage, we must also imagine the perpetrator so vacillating an idiot as to have abandoned his gold and his motive together.

“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.
