Williamson had fallen backwards with her head to the door; the servant, from her kneeling posture, had been incapable of rising, and had presented her head passively to blows; after which, the miscreant had but to bend her head backwards so as to expose her throat, and the murder was finished. It is remarkable that the young artisan, paralyzed as he had been by fear, and evidently fascinated for a time so as to walk right towards the lion's mouth, yet found himself able to notice everything important. The reader must suppose him at this point watching the murderer whilst hanging over the body of Mrs. Williamson, and whilst renewing his search for certain important keys. Doubtless it was an anxious situation for the murderer; for, unless he speedily found the keys wanted, all this hideous tragedy would end in nothing but a prodigious increase of the public horror, in tenfold precautions therefore, and redoubled obstacles interposed between himself and his future game. Nay, there was even a nearer interest at stake; his own immediate safety might, by a probable accident, be compromised. Most of those who came to the house for liquor were giddy girls or children, who, on finding this house closed, would go off carelessly to some other; but, let any thoughtful woman or man come to the door now, a full quarter of an hour before the established time of closing, in that case suspicion would arise too powerful to be checked. There would be a sudden alarm given; after which, mere luck would decide the event. For it is a remarkable fact, and one that illustrates the singular inconsistency of this villain, who, being often so superfluously subtle, was in other directions so reckless and improvident, that at this very moment, standing amongst corpses that had deluged the little parlor with blood, Williams must have been in considerable doubt whether he had any sure means of egress. There were windows, he knew, to the back; but upon what ground they opened, he seems to have had no certain information; and in a neighborhood so dangerous, the windows of the lower story would not improbably be nailed down; those in the upper might be free, but then came the necessity of a leap too formidable. From all this, however, the sole practical inference was to hurry forward with the trial of further keys, and to detect the hidden treasure. This it was, this intense absorption in one overmastering pursuit, that dulled the murderer's perceptions as to all around him; otherwise, he must have heard the breathing of the young man, which to himself at times became fearfully audible. As the murderer stood once more over the body of Mrs. Williamson, and searched her pockets more narrowly, he pulled out various clusters of keys, one of which dropping, gave a harsh gingling sound upon the floor. At this time it was that the secret witness, from his secret stand, noticed the fact of Williams's surtout being lined with silk of the finest quality.
