But Sam did not move. He stood as if turned to stone, gazing where the light shone upon Harry Frere's thin, worn face, and reading recognition in the eyes fixed full upon his. "Oh!" he cried, with a sob, and forgetting everything he sprang to the side of the litter and dropped upon his knees. "Mr Harry at last!" The doctor could not speak, as he saw his old companion raise his right hand and lay it upon the servant's shoulder, while the professor uttered a strange sound, which, if it had escaped a woman's breast would have been termed a sob. Then the doctor spoke. "That will do," he said sternly. "Obey my orders at once. The rest must wait till we are safe." Sam sprang up to fetch what was required, and the professor made an effort to recover his composure, the demand made upon him by his old school-fellow's condition rousing him to action. "One word only," said the prisoner faintly. "You said my brother--" "He is yonder," said the doctor quietly; "ill, but not seriously. You must not see him now. His _ruse_ has succeeded, and we have you here. Now I must see to your arm." "No, no, not now," said Harry excitedly; "we must make some plan or another about escaping. You must not stay here--you will be discovered." "Leave that to us," said the doctor sternly. "No, no," cried his new patient. "I have nearly been driven mad during my long imprisonment, but if aught happens to you all I shall go quite out of my mind in my despair." "Silence!" said the doctor sternly. "You are badly hurt, and your injury is telling upon your brain. I will not have you dwell upon our position. Look here, you can trust us. We have found our way here, found you, and had you brought to us. Give up to us at once, and trust to our doing what is best." "Yes, yes," said the poor fellow passionately; "but you do not understand. Never mind my arm. I will keep still, and the fracture will mend of itself." "Will it?" said the doctor grimly. "Yes, yes; but look here," whispered the sufferer; "we must talk; we must decide upon some action." "No," said the doctor, "not now. You do not understand our position." "I can guess it," said the poor fellow wildly. "Think then of mine. I am brought here for you to set my arm; in half an hour at the outside I shall be taken back to my owner. We may not have another opportunity to speak--we may never meet again." "Now I insist," said the doctor firmly. "You will have plenty of time to talk to us by and by." "No, no; you do not understand, Morris." "But the Hakim does," said the doctor grimly. "Now I order you to trust to me and wait."
