Returning home from some sailors’ frolic the night, or rather in the morning of the murder, he found the beast occupying his own bed-room, into which it had broken from a closet adjoining, where it had been, as was thought, securely confined.  Razor in hand, and fully lathered, it was sitting before a looking-glass, attempting the operation of shaving, in which it had no doubt previously watched its master through the key-hole of the closet.  Terrified at the sight of so dangerous a weapon in the possession of an animal so ferocious, and so well able to use it, the man, for some moments, was at a loss what to do.  He had been accustomed, however, to quiet the creature, even in its fiercest moods, by the use of a whip, and to this he now resorted.  Upon sight of it, the Ourang-Outang sprang at once through the door of the chamber, down the stairs, and thence, through a window, unfortunately open, into the street.

The Frenchman followed in despair; the ape, razor still in hand, occasionally stopping to look back and gesticulate at its pursuer, until the latter had nearly come up with it.  It then again made off.  In this manner the chase continued for a long time.  The streets were profoundly quiet, as it was nearly three o’clock in the morning.  In passing down an alley in the rear of the Rue Morgue, the fugitive’s attention was arrested by a light gleaming from the open window of Madame L’Espanaye’s chamber, in the fourth story of her house.  Rushing to the building, it perceived the lightning rod, clambered up with inconceivable agility, grasped the shutter, which was thrown fully back against the wall, and, by its means, swung itself directly upon the headboard of the bed.  The whole feat did not occupy a minute.  The shutter was kicked open again by the Ourang-Outang as it entered the room.

The sailor, in the meantime, was both rejoiced and perplexed.  He had strong hopes of now recapturing the brute, as it could scarcely escape from the trap into which it had ventured, except by the rod, where it might be intercepted as it came down.  On the other hand, there was much cause for anxiety as to what it might do in the house.  This latter reflection urged the man still to follow the fugitive.  A lightning rod is ascended without difficulty, especially by a sailor; but, when he had arrived as high as the window, which lay far to his left, his career was stopped; the most that he could accomplish was to reach over so as to obtain a glimpse of the interior of the room.  At this glimpse he nearly fell from his hold through excess of horror.  Now it was that those hideous shrieks arose upon the night, which had startled from slumber the inmates of the Rue Morgue.  Madame L’Espanaye and her daughter, habited in their night clothes, had apparently been occupied in arranging some papers in the iron chest already mentioned, which had been wheeled into the middle of the room.  It was open, and its contents lay beside it on the floor.  The victims must have been sitting with their backs toward the window; and, from the time elapsing between the ingress of the beast and the screams, it seems probable that it was not immediately perceived.  The flapping-to of the shutter would naturally have been attributed to the wind.
