A door opened, and we stepped into a hall, which, owing to the echo of my conductor’s voice, I concluded was a spacious one, but ere I had time to reflect, the man whose arm I held said:

“Just a moment. You must sign the visitors’ book—it is the rule here. We’ll excuse bad writing as you can’t see,” he added with a laugh.

At the same moment I felt a pen placed in my fingers by a man-servant, who guided my hand to the book. Then I hastily scrawled my name.

It was strange, I thought; but the events of the evening were all so extraordinary that there was nothing after all very unusual in signing a visitors’ book.

Again he took my arm, leading me up a long flight of stairs, the carpet of which was so thick that our feet fell noiselessly. In the ascent I felt that the balustrade was cold and highly polished, like glass. Confused and mysterious whisperings sounded about me, and I felt confident that I distinctly heard a woman’s sob quite close to me, while at the same moment a whiff of violets greeted my nostrils. Its fragrance stirred my memory—it was Sybil’s favourite perfume. Suddenly my guide ushered me into a room and took the handkerchief from my eyes. The apartment was a small study, cozy and well furnished, with a bright fire burning in the grate, and lit only by a green-shaded reading-lamp.

“If you’ll take off your overcoat and wait here a few moments I will bring her to you,” he said; adding, “you can talk here alone and undisturbed,” and he went out, closing the door after him.

Five eager minutes passed while I listened for her footstep, expecting each second to hear her well-known voice; but gradually the atmosphere seemed to become stifling. In my mouth was a sulphurous taste, and the lamp, growing more dim, at last gave a weak flicker and went out. Rushing to the door, I found, to my astonishment, it was locked!

I dashed to the window and tried to open it, but could not. In despair I beat the door frantically with my fists and shouted. But my muffled voice seemed as weak as a child’s. I doubted whether it could be heard beyond the walls.

Flinging myself upon my knees, I bent to examine the small fire, glowing like a blacksmith’s forge, and discovered to my horror that the chimney had been closed, and that the grate was filled with burning charcoal. Quickly I raked it out, but the red cinders only glowed the brighter, and, even though I dashed the hearthrug upon them, I could not extinguish them.

In desperation I tried to struggle to my feet, but failed. My legs refused to support me; my head throbbed as if my skull would burst. Then a strange sensation of nausea crept over me; my starting eyes smarted as if acid had been flung into them, my tongue clave to the roof of my parched mouth, my chest seemed held in contraction by a band of iron, as half rising I fell next second, inert and helpless, a sudden darkness obliterating all my senses.
