"Excellent," said Candron. He smiled as he hung up. Then he punched another secret number. This one connected him with the guards outside Ch'ien's apartment. As General Soong, he warned them of the coming of Dr. Wan. Then he went to the window, stepped out, and headed for the roof again. * * * * * There was no danger that the calls would be suspected. Those two phones could not be contacted except from inside the Palace, and not even then unless the number was known. Again he dropped down Elevator Shaft Three. Only Number One was operating this late in the evening, so there was no fear of meeting it coming up. He dropped lightly to the roof of the car, where it stood empty in the basement, opened the escape hatch in the roof, dropped inside, opened the door, and emerged into the first basement. Then he started down the stairs to the subbasement. The guards were not the least suspicious, apparently. Candron wished he were an honest-to-God telepath, so he could be absolutely sure. The officer at the end of the corridor that led to Ch'ien's apartment was a full captain, a tough-looking, swarthy Mongol with dark, hard eyes. "You are Dr. Wan?" he asked in a guttural baritone. "I am," Candron said. This was no place for traditional politeness. "Did not General Soong call you?" "He did, indeed, doctor. But I assumed you would be carrying--" He gestured, as though not quite sure what to say. Candron smiled blandly. "Ah. You were expecting the little black bag, is it not so? No, my good captain; I am a psychologist, not a medical doctor." The captain's face cleared. "So. The persuasion is to be of the more subtle type." "Indeed. Only thus can we be assured of his co-operation. One cannot force the creative mind to create; it must be cajoled. Could one have forced the great K'ung Fu-tse to become a philosopher at the point of a sword?" "It is so," said the captain. "Will you permit me to search you?" The affable Dr. Wan emptied his pockets, then permitted the search. The captain casually looked at the identification in the wallet. It was, naturally, in perfect order for Dr. Wan. The identification of Ying Lee had been destroyed hours ago, since it was of no further value. "These things must be left here until you come out, doctor," the captain said. "You may pick them up when you leave." He gestured at the pack of cigarettes. "You will be given cigarettes by the interior guard. Such are my orders." "Very well," Candron said calmly. "And now, may I see the patient?" He had wanted to keep those cigarettes. Now he would have to find a substitute. The captain unlocked the heavy door. At the far end, two more guards sat, complacently playing cards, while a third stood at a door a few yards away. A television screen imbedded in the door was connected to an interior camera which showed the room within.
