Foo Cha glided out disappointed. Something had gone terribly wrong, he was sure of that. He went slowly downstairs, his eyes fixed upon the dark figure standing motionless in the dimly-lit hall. He drew a sharp breath, which sounded through his yellow, protuberant teeth like a hiss. A single stroke of that long knife--it would be so easy. Then he remembered the respect with which Mr. Sabin had treated that card, and he sighed. Perhaps it would be a mistake; it might make evil worse. He beckoned to the stranger, and conducted him upstairs. Mr. Sabin received his visitor standing. He was still very pale, but his face had resumed its wonted impassiveness. In the dim lamp-lit room he could see very little of his visitor, only a thick-set man with dark eyes and a closely-cropped black beard. He was roughly dressed, yet held himself well. The two men eyed one another steadily for several moments, before any speech passed between them. "You are surprised," the stranger said; "I do not wonder at it. Perhaps--you have been much engrossed, it is said--you had even forgotten." Mr. Sabin's lips curled in a bitter smile. "One does not forget those things," he said. "To business. Let me know what is required of me." "It has been reported," the stranger said, "that you have conceived and brought to great perfection a comprehensive and infallible scheme for the conquest of this country. Further, that you are on the point of handing it over to the Emperor of Germany, for the use of that country. I think I may conclude that the report is correct?" he added, with a glance at the table. "We are not often misinformed." "The report," Mr. Sabin assented, "is perfectly correct." "We have taken counsel upon the matter," the stranger continued, "and I am here to acquaint you with our decision. The papers are to be burnt, and the appliances to be destroyed forthwith. No portion of them is to be shown to the German Government or any person representing that country, nor to any other Power. Further, you are to leave England within two months."
