It was upon one of the longest of all my excursions of discovery in the deserted portion of the castle, less than a week before that fatal hour which I felt must mark the utmost limit of my stay on earth, beyond which I could have not even the slightest hope of continuing to draw breath, that I came upon the culminating event of my whole life. I had spent the better part of the morning in climbing up and down half ruined staircases in one of the most dilapidated of the ancient turrets. As the afternoon progressed, I sought the lower levels, descending into what appeared to be either a mediaeval place of confinement, or a more recently excavated storehouse for gunpowder. As I slowly traversed the nitre-encrusted passageway at the foot of the last staircase, the paving became very damp, and soon I saw by the light of my flickering torch that a blank, water-stained wall impeded my journey. Turning to retrace my steps, my eye fell upon a small trap-door with a ring, which lay directly beneath my feet. Pausing, I succeeded with difficulty in raising it, whereupon there was revealed a black aperture, exhaling noxious fumes which caused my torch to sputter, and disclosing in the unsteady glare the top of a flight of stone steps. As soon as the torch, which I lowered into the repellent depths, burned freely and steadily, I commenced my descent. The steps were many, and led to a narrow stone-flagged passage which I knew must be far underground. This passage proved of great length, and terminated in a massive oaken door, dripping with the moisture of the place, and stoutly resisting all my attempts to open it. Ceasing after a time my efforts in this direction, I had proceeded back some distance toward the steps, when there suddenly fell to my experience one of the most profound and maddening shocks capable of reception by the human mind. Without warning, =I heard the heavy door behind me creak slowly open upon its rusted hinges=. My immediate sensations are incapable of analysis. To be confronted in a place as thoroughly deserted as I had deemed the old castle with evidence of the presence of man or spirit, produced in my brain a horror of the most acute description. When at last I turned and faced the seat of the sound, my eyes must have started from their orbits at the sight that they beheld. There in the ancient Gothic doorway stood a human figure. It was that of a man clad in a skull-cap and long mediaeval tunic of dark colour. His long hair and flowing beard were of a terrible and intense black hue, and of incredible profusion. His forehead, high beyond the usual dimensions; his cheeks, deep sunken and heavily lined with wrinkles; and his hands, long, claw-like and gnarled, were of such a deathly, marble-like whiteness as I have never elsewhere seen in man. His figure, lean to the proportions of a skeleton, was strangely bent and almost lost within the voluminous folds of his peculiar garment. But
