It was not likely, after such an exciting day, that I should pass a good night. My rest was greatly disturbed; and at about three o'clock I was wide awake. My wife was sleeping soundly. I rose quietly, thrust my feet in my slippers, and went downstairs to the dining-room. There lay the cat with its eyes wide open. "You infernal creature," I cried, holding the candle so that its light fell upon the specter, "what are you here for? What do you want me to do? Why do you not go back to your grave and leave me in peace?" I asked these questions slowly, and paused between each, with an insane notion that an answer might be given to them. No answer was vouchsafed, and I recognized the folly of my expectation. The peculiarity of the apparition was that its eyes never seemed to be closed, as the eyes of other cats are when they are in repose. It appeared to be ever on the watch, but what it was watching for was a sealed mystery to me. In a moment of exasperation I raised my hand against it threateningly; it did not move. I went no further than this, feeling that it would be cowardly to strike at a shadow. I returned to my bedroom, and after tossing about for an hour fell into a disturbed sleep. Bob lived at Canonbury, and had given me directions to take a North London train, his station being about half a mile from his lodgings. All the day the cat had remained in the dining-room, but when I was leaving the house on my visit to Bob, it rose and followed me. "Do you intend to favor me with your company?" I asked. "Very well, come along." And come along it did, to the train I took, got into the carriage with me, and emerged from it at the Canonbury station, where I found Bob waiting for me on the platform. "I have brought another visitor with me, Bob," I said, "but I can assure you it has accompanied me without any invitation." "Is it here, then?" he asked, following the direction of my eyes. "Yes, Bob, it is here." And as we walked to the old-fashioned house in which he rented one room at the top, I remarked, "Is it not singular that it did not come to the theater with me last night, and that it should accompany me now upon this friendly visit to you?" Bob nodded. "I am beginning to have theories about it," I continued, "and one is, that something will occur to-night in connection with the haunted house in Lamb's Terrace." "Do not get too many fancies into your head, old fellow," said Bob. "I will not get more than I can help, but ideas come without any active prompting or wish of my own; I am like a man who is being driven, or led." Bob's one room was by no means uncomfortable; it served at once for his living and bedroom, but the bed he occupied being a folding bed, and the washstand he used being inclosed, it did not present the appearance of a bedroom. There were shelves on the walls containing a large number of books; four or five of these were on the table.
