“It’s almost enough to make any one believe in ghosts,” he commented to himself. “But that was not a ghost, and I was not dreaming. A young woman stood right there! She apparently came into the room by mistake; may have tried to enter for the purpose of assassinating me! Which was it? And wasn’t John Latimer lying again when he said what he did about it?” Lying down fully dressed, the scout awaited something--he did not know what. He began to feel that his nerves were badly upset. Presently, thinking he heard soft footsteps somewhere, he again left the room quietly and went in search of them. He even went out of the house, and looked round outside, carrying his revolver ready for use, for the mystery of all these things filled him with something as near to fear as he had ever known. As he returned to the door by which he had left the house he was startled by hearing voices; then, in the half darkness of the shaded piazza, he saw again the girl. Here was confirmation of the fact that he had not been asleep and dreamed that he saw this woman. She was talking with some one; and the scout saw at her side a young man. He was about to advance and demand an explanation, when the girl opened the door behind her, and she and the young man vanished into the house. Buffalo Bill, having come out by that door, had left it unlocked. Now, when he ran up to it, he found that it was locked from the inside. He was left out of the house; and to get in he was compelled to call up John Latimer once more, doing it this time by shouting to him below his window. Latimer appeared, coming down into the lower hall in a red dressing gown and slippers. “What is it, Cody?” Buffalo Bill told him. “Come here, Cody!” He lighted a candle and led the way into a small side room, where, instead of answering Buffalo Bill’s questions, he looked at him strangely, and then took down some small bottles from a shelf. “I studied medicine once, Cody, and keep medicines here for my own use. You must let me prescribe for you.” “You mean to say I did not see and hear that young woman and young man?” “I think you are not well, Cody,” was the evasive reply. “Permit me to prescribe for you.” He poured some of the contents of one of the bottles into a glass. “No!” said the scout. “I am not ill; there’s nothing the matter with me. I need no medicine.” Latimer came and looked him closely in the face, holding up the candle. “Cody, I insist that no young man or young woman is on this place, so far as I know. But----” He hesitated. “Finish the sentence,” the scout urged. “Well, what I mean to remind you of is that there have been strange happenings in this house. I’ve mentioned them. These are some of the mysterious things which I told you would make me superstitious, if there were any superstition in my nature.” “You have seen this young man and woman?”
