They went upstairs together, and a moment later Rumsey found himself in the palatial chamber which had been prepared for him. He was not really sleepy and decided to sit up for a little. A fire burned in the grate, some books lay about--he drew his easy-chair forward and taking up a volume of light literature prepared to dip into it--he found that it was Stevenson's "Treasure Island," a book which he had not yet happened to read; the story interested him, and he read on for some time. Presently he closed the book, and laying his head against the cushion of the chair dropped fast asleep. The events of the day made him dream; all his dreams were about his queer patient. He thought that he had followed Awdrey on to the Plain--that Awdrey's excitement grew worse and worse, until the last lingering doubt was solved, and the man was in very truth absolutely insane. In the midst of his dream the doctor was awakened by a hand being laid on his shoulder--he started up suddenly--Awdrey, half-dressed and looking ghastly pale, stood before him. "What is it?" said Rumsey. "Do you want anything?" "I want you," said Awdrey. "Will you come with me?" "Certainly--where am I to go? Why are you not in bed?" Awdrey uttered a hollow laugh. There was a ring of horror in it. "You could not sleep if you were me," he said. "Will you come with me now, at once?" "In a moment or two when you are better--sit down, won't you--here, take my chair--where do you want me to go?" "Out with me, doctor--out of doors. I want you to accompany me on to the Plain." "All right, my dear fellow--but just allow me to get on my boots." The doctor retired to a back part of the room to change his house shoes. While he was doing so, Awdrey sank down on a chair and laid his hands on his knees, took no notice of Rumsey, but stared straight before him into the centre of the room. "I wish you'd be quick, doctor," he said at last. "I don't want to go alone, but I must follow it." "Follow what?" said Rumsey. "It--the queer vision--I have told you of it before." "Oh, yes, that bad dream you are subject to. Well, I am at your service now." Awdrey rose slowly. He pointed with one of his hands. "Do you see that?" he said suddenly. Rumsey following the direction of his eyes perceived that he was staring into the part of the room which was in deepest shadow. "I see nothing, Awdrey," he replied in a kind and soothing voice, "but I perceive by your manner that you do. What is it?" "I wonder you cannot see it," replied Awdrey; "it is plain, too plain--it seems to fill all that part of the room." "The old thing?" asked the doctor. "Yes, the old thing but with a certain difference. There is the immense globe of light and the picture in the middle." "The old picture, Awdrey?"
