She got to her feet again. "I want to pay my debt," she said solemnly. "It is a debt that one day must be paid--so awful--so awful!" A swift change passed over her. She shuddered, and grew white. "I said brave words just now," she added in a hoarse whisper, "but now I see him lying there cold and still, and you stooping over him. I see you touch his breast, his pulse. I see you close his eyes. One instant full of the pulse of life, the next struck out into infinite space. Oh, I shall never--how can I ever-forget!" She turned her head away from him, then composed herself again, and said quietly, with anxious eyes: "Why was nothing said or done? Perhaps they are only waiting. Perhaps they know. Why was it announced that he died in his bed at home?" "I cannot tell. When a man in high places dies in Egypt, it may be one death or another. No one inquires too closely. He died in Kaid Pasha's Palace, where other men have died, and none has inquired too closely. To-day they told me at the Palace that his carriage was seen to leave with himself and Mizraim the Chief Eunuch. Whatever the object, he was secretly taken to his house from the Palace, and his brother Nahoum seized upon his estate in the early morning. "I think that no one knows the truth. But it is all in the hands of God. We can do nothing more. Thee must go. Thee should not have come. In England thee will forget, as thee should forget. In Egypt I shall remember, as I should remember." "Thee," she repeated softly. "I love the Quaker thee. My grandmother was an American Quaker. She always spoke like that. Will you not use thee and thou in speaking to me, always?" "We are not likely to speak together in any language in the future," he answered. "But now thee must go, and I will--" "My cousin, Mr. Lacey, is waiting for me in the garden," she answered. "I shall be safe with him." She moved towards the door. He caught the handle to turn it, when there came the noise of loud talking, and the sound of footsteps in the court-yard. He opened the door slightly and looked out, then closed it quickly. "It is Nahoum Pasha," he said. "Please, the other room," he added, and pointed to a curtain. "There is a window leading on a garden. The garden-gate opens on a street leading to the Ezbekiah Square and your hotel." "But, no, I shall stay here," she said. She drew down her veil, then taking from her pocket another, arranged it also, so that her face was hidden. "Thee must go," he said--"go quickly." Again he pointed. "I will remain," she rejoined, with determination, and seated herself in a chair. CHAPTER X THE FOUR WHO KNEW There was a knocking at the door. David opened it. Nahoum Pasha stepped inside, and stood still a moment looking at Hylda. Then he made low salutation to her, touched his hand to his lips and breast saluting David, and waited. "What is thy business, pasha?" asked David quietly, and motioned towards a chair.
