What was the murderer's meaning in coming along the passage to the front door? The meaning was this: separately, as an individual, Mary was worth nothing at all to him. But, considered as a member of a household, she had this value, viz., that she, if caught and murdered, perfected and rounded the desolation of the house. The case being reported, as reported it would be all over Christendom, led the imagination captive. The whole covey of victims was thus netted; the household ruin was thus full and orbicular; and in that proportion the tendency of men and women, flutter as they might, would be helplessly and hopelessly to sink into the all-conquering hands of the mighty murderer. He had but to say—my testimonials are dated from No. 29 Ratcliffe Highway, and the poor vanquished imagination sank powerless before the fascinating rattlesnake eye of the murderer. There is not a doubt that the motive of the murderer for standing on the inner side of Marr's front-door, whilst Mary stood on the outside, was—a hope that, if he quietly opened the door, whisperingly counterfeiting Marr's voice, and saying, What made you stay so long? possibly she might have been inveigled. He was wrong; the time was past for that; Mary was now maniacally awake; she began now to ring the bell and to ply the knocker with unintermitting violence. And the natural consequence was, that the next door neighbor, who had recently gone to bed and instantly fallen asleep, was roused; and by the incessant violence of the ringing and the knocking, which now obeyed a delirious and uncontrollable impulse in Mary, he became sensible that some very dreadful event must be at the root of so clamorous an uproar. To rise, to throw up the sash, to demand angrily the cause of this unseasonable tumult, was the work of a moment. The poor girl remained sufficiently mistress of herself rapidly to explain the circumstance of her own absence for an hour; her belief that Mr. and Mrs. Marr's family had all been murdered in the interval; and that at this very moment the murderer was in the house.
The person to whom she addressed this statement was a pawnbroker; and a thoroughly brave man he must have been; for it was a perilous undertaking, merely as a trial of physical strength, singly to face a mysterious assassin, who had apparently signalized his prowess by a triumph so comprehensive. But, again, for the imagination it required an effort of self-conquest to rush headlong into the presence of one invested with a cloud of mystery, whose nation, age, motives, were all alike unknown. Rarely on any field of battle has a soldier been called upon to face so complex a danger. For if the entire family of his neighbor Marr had been exterminated, were this indeed true, such a scale of bloodshed would seem to argue that there must have been two persons as the perpetrators; or if one singly had accomplished such a ruin, in that case how colossal must have been his audacity! probably, also, his skill and animal power! Moreover, the unknown enemy (whether single or double) would, doubtless, be elaborately armed. Yet, under all these disadvantages, did this fearless man rush at once to the field of butchery in his neighbor's house. Waiting only to draw on his trousers, and to arm himself with the kitchen poker, he went down into his own little back-yard. On this mode of approach, he would have a chance of intercepting the murderer; whereas from the front there would be no such chance; and there would also be considerable delay in the process of breaking open the door. A brick wall, nine or ten feet high, divided his own back premises from those of Marr. Over this he vaulted; and at the moment when he was recalling himself to the necessity of going back for a candle, he suddenly perceived a feeble ray of light already glimmering on some part of Marr's premises. Marr's back-door stood wide open. Probably the murderer had passed through it one half minute before. Rapidly the brave man passed onwards to the shop, and there beheld the carnage of the night stretched out on the floor, and the narrow premises so floated with gore, that it was hardly possible to escape the pollution of blood in picking out a path to the front-door. In the lock of the door still remained the key which had given to the unknown murderer so fatal an advantage over his victims. By this time, the heart- shaking news involved in the outcries of Mary (to whom it occurred that by possibility some one out of so many victims might still be within the reach of medical aid, but that all would depend upon speed) had availed, even at that late hour, to gather a small mob about the house. The pawnbroker threw open the door. One or two watchmen headed the crowd; but the soul-harrowing spectacle checked them, and impressed sudden silence upon their voices, previously so loud. The tragic drama read aloud its own history, and the succession of its several steps—few and summary. The murderer was as yet altogether unknown; not even suspected. But there were reasons for thinking that he must have been a person familiarly known to Marr. He had entered the shop by opening the door after it had been closed by Marr. But it was justly argued—that, after the caution conveyed to Marr by the watchman, the appearance of any stranger in the shop at that hour, and in so dangerous a neighborhood, and entering by so irregular and suspicious a course, (i.e., walking in after the door had been closed, and after the closing of the shutters had cut off all open communication with the street), would naturally have roused Marr to an attitude of vigilance and self-defence. Any indication, therefore, that Marr had not been so roused, would argue to a certainty that something had occurred to neutralize this alarm, and fatally to disarm the prudent jealousies of Marr. But this 'something' could only have lain in one simple fact, viz., that the person of the murderer was familiarly known to Marr as that of an ordinary and unsuspected acquaintance. This being presupposed as the key to all the rest, the whole course and evolution of the subsequent drama becomes clear as daylight. The murderer, it is evident, had opened gently, and again closed behind him with equal gentleness, the street-door. He had then advanced to the little counter, all the while exchanging the ordinary salutation of an old acquaintance with the unsuspecting Marr. Having reached the counter, he would then ask Marr for a pair of unbleached cotton socks. In a shop so small as Marr's, there could be no great latitude of choice for disposing of the different commodities. The arrangement of these had no doubt become familiar to the murderer; and he had already ascertained that, in order to reach down the particular parcel wanted at present, Marr would find it requisite to face round to the rear, and, at the same moment, to raise his eyes and his hands to a level eighteen inches above his own head. This movement placed him in the most disadvantageous possible position with regard to the murderer, who now, at the instant when Marr's hands and eyes were embarrassed, and the back of his head fully exposed, suddenly from below his large surtout, had unslung a heavy ship-carpenter's mallet, and, with one solitary blow, had so thoroughly stunned his victim, as to leave him incapable of resistance. The whole position of Marr told its own tale. He had collapsed naturally behind the counter, with his hands so occupied as to confirm the whole outline of the affair as I have here suggested it. Probable enough it is that the very first blow, the first indication of treachery that reached Marr, would also be the last blow as regarded the abolition of consciousness. The murderer's plan and rationale of murder started systematically from this infliction of apoplexy,
