“He does that half-a-dozen times a day,” said John. “He sees something which he both hates and fears.” I walked to the gate and looked over it. Something was moving on the grass outside, and soon a sound which I could not instantly identify came to my ears. Then I remembered what it was: it was the purring of a cat. I lit a match, and saw the purrer, a big blue Persian, walking round and round in a little circle just outside the gate, stepping high and ecstatically, with tail carried aloft like a banner. Its eyes were bright and shining, and every now and then it put its head down and sniffed at the grass. I laughed. “The end of that mystery, I am afraid,” I said. “Here’s a large cat having Walpurgis night all alone.” “Yes, that’s Darius,” said John. “He spends half the day and all night there. But that’s not the end of the dog mystery, for Toby and he are the best of friends, but the beginning of the cat mystery. What’s the cat doing there? And why is Darius pleased, while Toby is terror-stricken?” At that moment I remembered the rather horrible detail of my dreams when I saw through the gate, just where the cat was now, the white tombstone with the sinister inscription. But before I could answer the rain began, as suddenly and heavily as if a tap had been turned on, and simultaneously the big cat squeezed through the bars of the gate, and came leaping across the lawn to the house for shelter. Then it sat in the doorway, looking out eagerly into the dark. It spat and struck at John with its paw, as he pushed it in, in order to close the door. Somehow, with the portrait of Julia Stone in the passage outside, the room in the tower had absolutely no alarm for me, and as I went to bed, feeling very sleepy and heavy, I had nothing more than interest for the curious incident about our bleeding hands, and the conduct of the cat and dog. The last thing I looked at before I put out my light was the square empty space by my bed where the portrait had been. Here the paper was of its original full tint of dark red: over the rest of the walls it had faded. Then I blew out my candle and instantly fell asleep. My awaking was equally instantaneous, and I sat bolt upright in bed under the impression that some bright light had been flashed in my face, though it was now absolutely pitch dark. I knew exactly where I was, in the room which I had dreaded in dreams, but no horror that I ever felt when asleep approached the fear that now invaded and froze my brain. Immediately after a peal of thunder crackled just above the house, but the probability that it was only a flash of lightning which awoke me gave no reassurance to my galloping heart. Something I knew was in the room with me, and instinctively I put out my right hand, which was nearest the wall, to keep it away. And my hand touched the edge of a picture-frame hanging close to me.
