“Yes, I have seen them. And then I promptly dosed myself for the benefit of my nerves; not being sure then, or now, that I had seen anything at all. But if there are ghosts in this house----” “Stuff and nonsense!” said the scout. “I saw a young man and young woman standing together on the piazza, and heard them talking. They came into the house; and they locked from the inside the door I had unlocked, so that I had to call to you to get in. That wasn’t the work of ghosts. What became of them?” “Cody,” said Latimer impressively, “what became of Nomad?” He looked at Buffalo Bill again in that peculiar manner. “Cody,” he said impressively, “I’ll tell you now something I have not hinted at. A young woman and her lover, who at the time were occupying the house here in my absence, were killed here. Who committed the murder, or why, was never shown; but I suspected the Redskin Rovers. On two occasions since then I myself have fancied that I saw a young man and a young woman here; but I knew then, and know now, that it was only fancy, a result of a heated imagination. A good many things have happened to-day to upset you, and they have excited your mind and made it morbid. So you fancied you saw the young man and the young woman.” To Buffalo Bill it seemed that Latimer was trying to throw him off the scent. Yet he could hardly see how Latimer would expect him to believe this unlikely statement. “No matter how excited I might be, is it probable,” he asked, “that I would chance to see the young man and the young woman that you did, when I had never so much as heard of them or their murder, and therefore they could not have been in my mind?” “There are strange things in this world, Cody.” “I agree with you.” It was not the least strange to him that Latimer should seek to make him believe in this ghost yarn. Again the impression was driven in on him that Latimer was concealing a great deal and was not acting in a manner that could be considered straightforward. This caused the scout to feel more strongly that great danger surrounded him, and that he must guard against it, even though he could not foresee the direction from which it would come. CHAPTER IX. THE REDSKIN ROVERS. Unable to sleep, for thoughts of the mysteries surrounding him, Buffalo Bill was wide awake and fully dressed when the redskins made their attack on the house. The attack came shortly before morning, in the darkest part of the night. There came first the clattering sound of the hoofs of mustangs. This was followed by wild and startling Indian yells, accompanied by the discharge of firearms, and the patter of bullets and arrows against the walls. Buffalo Bill seized his revolvers and his rifle and ran out into the hall, and with quick bounds leaped down the broad stairway. He found John Latimer in the room below.
