“Sit down!” Sir Arthur shouted. “Sit down! God above, you’ll be telling me to keep calm next!” He flung himself into his chair. “Here I am then. Now get on!” He buried his face in his hands; then looked up to say: “You must forgive me, Gethryn; I’m not myself. I’ve been more on edge the last few days—a lot more—than I’ve let any one see. And to-night, somehow, my nerves have gone. And when you came with news I thought it meant that you’d caught the real murderer and that the boy would get off—and—and everything!” “I was going to tell you,” Anthony said, “that the murderer of John Hoode will never be caught. To get him is impossible. Please understand that when I say impossible I mean it.” “But why, man? Why?” cried Sir Arthur. “Because,” said Anthony slowly, “he doesn’t exist.” “What?” Sir Arthur was on his feet again at a bound astonishing in its agility. Anthony lay back in his chair. “I can’t bear it! I can’t bear it!” he said plaintively. “You know, you’re very violent to-night.

Following that lightning came peal after peal of thunder. As it died away, Anthony saw that the other was speaking. He had not moved in his chair, but his strong, square hands were twisting about each other to testify to the intensity of his emotion. “What are you telling me?” he whispered. “Are you mad? John not dead! John not dead! Why, it’s idiocy—stark idiocy to say what you have said!” Anthony shook his head. “It isn’t. Whatever it is, it isn’t that. Wait till I have told you more. It’s a long tale and strange.” Sir Arthur moistened his lips with his tongue but did not speak. Anthony’s words had carried conviction; his words and a way he had of commanding attention. The thunder, after the outburst of a moment before, seemed to have ceased entirely. No sudden furies of wind shook the house. The only sounds in the oppressive room were the tick-tick of the grandfather clock and the soft hish-hish of the rain against the closed windows. Anthony drew a deep breath, and began:—
