In that large house there was no human inmate save myself, and I had an attack of nervousness upon me for which I found it impossible to account. Here was I, at length, under the very roof where my mistress had passed all her childish days, bound to solve the mystery which was making such havoc with her young life, permitted to essay a task, the accomplishment of which should cover me with glory, and perhaps restore peace and happiness to her heart; and yet I was _afraid_. I did not hesitate to utter that word to my own soul then, any more than I hesitate to write it now for those who list to read: for I can truly say I think there are few men whose courage such an adventure would not try were they to attempt it; and I am sure, had any one of those to whom I tell this story been half as much afraid as I, he would have left River Hall there and then, and allowed the ghosts said to be resident, to haunt it undisturbed for evermore. If I could only have kept memory from running here and there in quest of evidence pro and con the house being haunted, I should have fared better: but I could not do this. Let me try as I would to give my attention to those legal studies that ought to have engrossed my attention, I could not succeed in doing so: my thoughts, without any volition on my part, kept continually on the move; now with Miss Blake in Buckingham Street, again with Colonel Morris on the river walk, once more with Miss Elmsdale in the library; and went constantly flitting hither and thither, recalling the experiences of a frightened lad, or the terror of an ignorant woman; yet withal I had a feeling that in some way memory was playing me false, as if, when ostentatiously bringing out all her stores for me to make or mar as I could, she had really hidden away, in one of her remotest corners, some link, great or little as the case might be, but still, whether great or little, necessary to connect the unsatisfactory narratives together. Till late in the night I sat trying to piece my puzzle together, but without success. There was a flaw in the story, a missing point in it, somewhere, I felt certain. I often imagined I was about to touch it, when, heigh! presto! it eluded my grasp. "The whole affair will resolve itself into ivy-boughs," I finally, if not truthfully, decided. "I am satisfied it is all--ivy," and I went to bed. Now, whether it was that I had thought too much of the ghostly narratives associated with River Hall, the storminess of the night, the fact of sleeping in a strange room, or the strength of a tumbler of brandy-and-water, in which brandy took an undue lead, I cannot tell; but during the morning hours I dreamed a dream which filled me with an unspeakable horror, from which I awoke struggling for breath, bathed in a cold perspiration, and with a dread upon me such as I never felt in any waking moment of my life.
