She shrank from the parapet as if she had been struck. “Tearing the pillars down,” she replied aghast; “this part of the palace will fall. Oh, what can be done!” There was a grinding of stone upon stone, a mad yell from an hundred throats, the crash of glass, and, with a thunderous sound, a colossal pillar fell to the earth. The roof beneath the feet of the princess and Thorndyke trembled and sagged, and the tiling split and showered about them. Raising Bernardino in his arms, as if she were an infant, Thorndyke sprang toward the stairway leading to his chambers, but the roof had sunken till it was steep and slippery. One instant he was toppling over backward, the next, by a mighty effort, he had recovered his equilibrium, and finally managed to reach a safer place. As he hurried on another pillar went down. The roof sagged lower, and an avalanche of mortar and tiling slid into the court below. Yells, groans, and cries of fury rent the air. Bernardino had fainted. Thorndyke tried to restore her to consciousness, but dared not put her from him for an instant. On he ran, and presently reached a flight of stairs which he thought led to his chambers. He descended them, and was hastening along a narrow corridor on the floor beneath when Bernardino opened her eyes. She asked to be released from his arms. He put her down, but supported her along the corridor. “We have lost our way,” he said, as he discovered that the corridor, instead of leading to his chambers, turned off obliquely in another direction. “Let's go on anyway,” she suggested; “it may lead us out. I have never been here before. I--” A great crash drowned her words. The floor quivered and swayed, but it did not fall. On they ran through the darkness, till Thorndyke felt a heavy curtain before. He paused abruptly, not knowing what to do. Bernardino felt of its texture, perplexed for an instant. “Draw it aside, it seems to hang across the corridor,” she said. He obeyed her, and only a few yards further on they saw another curtain with bars of light above and below it. They drew this aside, and found themselves on the threshold of a most beautiful apartment. In the mosaic floor were pictures cut in colored stones, and the ceiling was a silken canopy as filmy and as delicately blue as the sky on a summer's night. The floor was strewn with richly embroidered pillows, couches, rugs and ottomans; and here and there were palm trees and beds of flowers and grottoes. A solitary light, representing the moon, showed through the silken canopy in whose folds little lights sparkled like far-off stars. Thorndyke looked at the princess inquiringly. She was bewildered. “I have no idea where we are,” she murmured. “I am sure I have never been here before; but there is another apartment beyond. Listen! I hear cries.”
