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.
