I resumed my reading, and would doubtless have forgotten the vague, evanescent impression, had it not been that, having occasion a moment after to consult a certain volume, I found but a gap in the row where it ought to have stood, and the same instant remembered that just there I had seen, or fancied I saw, the old man in search of a book. I looked all about the spot but in vain. The next morning, however, there it was, just where I had thought to find it! I knew of no one in the house likely to be interested in such a book.

Three days after, another and yet odder thing took place.

In one of the walls was the low, narrow door of a closet, containing some of the oldest and rarest of the books. It was a very thick door, with a projecting frame, and it had been the fancy of some ancestor to cross it with shallow shelves, filled with book-backs only. The harmless trick may be excused by the fact that the titles on the sham backs were either humorously original, or those of books lost beyond hope of recovery. I had a great liking for the masked door.

To complete the illusion of it, some inventive workman apparently had shoved in, on the top of one of the rows, a part of a volume thin enough to lie between it and the bottom of the next shelf: he had cut away diagonally a considerable portion, and fixed the remnant with one of its open corners projecting beyond the book-backs. The binding of the mutilated volume was limp vellum, and one could open the corner far enough to see that it was manuscript upon parchment.

Happening, as I sat reading, to raise my eyes from the page, my glance fell upon this door, and at once I saw that the book described, if book it may be called, was gone. Angrier than any worth I knew in it justified, I rang the bell, and the butler appeared. When I asked him if he knew what had befallen it, he turned pale, and assured me he did not. I could less easily doubt his word than my own eyes, for he had been all his life in the family, and a more faithful servant never lived. He left on me the impression, nevertheless, that he could have said something more.

In the afternoon I was again reading in the library, and coming to a point which demanded reflection, I lowered the book and let my eyes go wandering. The same moment I saw the back of a slender old man, in a long, dark coat, shiny as from much wear, in the act of disappearing through the masked door into the closet beyond. I darted across the room, found the door shut, pulled it open, looked into the closet, which had no other issue, and, seeing nobody, concluded, not without uneasiness, that I had had a recurrence of my former illusion, and sat down again to my reading.

Naturally, however, I could not help feeling a little nervous, and presently glancing up to assure myself that I was indeed alone, started again to my feet, and ran to the masked door—for there was the mutilated volume in its place! I laid hold of it and pulled: it was firmly fixed as usual!

I was now utterly bewildered. I rang the bell; the butler came; I told him all I had seen, and he told me all he knew.

He had hoped, he said, that the old gentleman was going to be forgotten; it was well no one but myself had seen him. He had heard a good deal about him when first he served in the house, but by degrees he had ceased to be mentioned, and he had been very careful not to allude to him.

“The place was haunted by an old gentleman, was it?” I said.
