I handed the message to the strange man behind the wall, who immediately disappeared with it, closing the panel. “The worst is over,” thought I, while I stood in that mysterious and silent chamber waiting for his return. But I should not have thought so had I known what was still to be revealed to me before the dawn of another day, and in the months that followed, during which that house and its echoing groves were my home. And I sometimes ask myself, in the light of later events of which that visit was indirectly the cause, whether, had I been able to foresee them, I would still have persevered in my purpose to know the secrets of my uncle's house? CHAPTER IV A long time I stood waiting for some reply to my message. My candle was fast burning out, and I began to fear that after all I was likely to leave the house no wiser than when I had entered it. Suddenly a door swung on its creaking hinges and a feeble old man, holding a lamp in one hand, stood grinning at me in the opening. It was the same face that I saw before, but it seemed less ghostly and unnatural now. Stepping back he beckoned me to enter. As soon as I had crossed the threshold the door closed behind me and the old man carefully bolted it. I stood in a large room, richly furnished, of which spiders had apparently long held possession. Great cobwebs hung like hammocks from the ceiling, and the dust of years had settled over all. Two human skeletons completely wrapped in cobwebs, stood facing me against the opposite wall. Following my silent leader, I went through a long narrow passage, at the end of which was a heavy door fastened with large iron bolts. Before opening it the strange old man placed the lamp upon a table and turning around looked squarely into my face. Merciful Heaven! It was the face of another man who was looking at me now! The deep lines had almost disappeared and the eyes looked brighter and more intelligent. No, it was the same face, for while my eyes were eagerly scanning it that hideous grin began to deepen its wrinkles, and its owner, taking half a dozen steps down the passageway, made an awkward motion with both hands as if trying to indicate that I was to follow him very closely. Then he opened the big door and I was surprised to observe that it led into the outer air. What gulf of darkness are we about to plunge into? I asked myself, peering through the doorway; and as we stepped out I heard again that ominous whirring. Close upon his heels I followed in a narrow path, through what seemed to be a large courtyard, overgrown with thick grass. Presently he stopped, and, taking a bunch of keys from his pocket, unlocked a door in a back wing of the house. Reaching out until his hand touched me, as if to make sure that I was there, he swung the door open and we stepped into a dimly lighted apartment. My mysterious guide turned up the wick of a lamp that was burning on a table in the centre of the room. It was a library, with great shelves of books reaching
