Judge, then, of my surprise, on returning to a state of consciousness, to discover that I was on my feet in an erect position with my back against what seemed to be a stone pillar. It is not quite correct to define my attitude as "erect:" leaning forward would more aptly describe it. My balance was maintained by a contrivance of somewhat sinister significance. My hands were extended almost horizontally behind me, one on each side of the pillar, my wrists being firmly secured to each other by something which, judging by the sense of touch was a silken sash so twined and twisted as to serve the same purpose as a strong cord. My arms ached with the pain arising from the unnatural position in which they were sustained; and my head throbbed acutely, probably from the effects of the drug exhaled by the phial. In what place I stood it was impossible to tell, for there lay a darkness all around as black and oppressive as though a pall had been flung over me. Fear imparts the wildest fancies to the human mind. My first impression was that I had awoke on the other side of the dark river that parts this world from the next, and that my eyes, so soon as they were able to pierce the gloom, would discover scenes more terrible than those imagined by the genius of Dante. Reverting, however, to the train of events that had brought me to the state of unconsciousness, I came to the more rational conclusion that I was still in the Nuns' Tower. The stone column to which I was attached was without doubt the pillar that upheld the arched roof of the studio-cell; and the silken fabric that bound my hands, I felt intuitively, was the purple curtain that, earlier in the day, had been hung over the casement. My eyes, becoming by slow degrees accustomed to the darkness, discerned through the penumbra around me a grey oblong object elevated in air and crowned with a triangular apex, which finally resolved itself into the shape of a Gothic casement; and then little by little the whole perspective of the studio-cell became dimly outlined on my vision; and there, by the side of the table, within the oaken chair, sat a figure. My first impulse was to shout for help, but I checked myself lest such cry should be the signal for my mysterious captor to despatch me. How he had gained access to the cell was evident. At a point equidistant from the window and the door a slab of stone that formed a part of the flooring was raised, and reclined obliquely against the wall. Beneath the place where it had lain an opening yawned, and the faint outline of steps going downwards proved the truth of the statement contained in the addendum to the antiquary's book that there was another mode of communicating with the tower besides the ordinary way of the door.
