Reluctantly the Prince consented, and she glided away from him with soundless footsteps. Close, close behind her he followed till they reached the threshold of the Cave Hall. There he tarried out of sight, yet where his eyes could still keep guard over her.
The Wizard, provoked beyond measure by the inattention of his servants, was about to rise from his chair to go and learn the reason, and to punish them, when suddenly a low-toned laugh struck on his ears. It startled him, for it was the familiar laughter of his sister—his sister, whom he believed to be far away, hopelessly imprisoned in the deepest recesses of his cavern. He turned his head in the direction from whence it came, and as he half rose from his seat, puzzled and uncertain, it echoed a second time through the Cave. It came from close by, in that dusky corridor that led to his own bedchamber, led to the rooms beyond where the Imps were busy, ay—and led on still further to his Pit of Fumes. By that way his sister could not pass. He smiled cruelly as he thought of that inconquerable barrier to her coming. By the other way there was the double wall, sealed by his enchantment. Remembering these things he was certain that he but imagined that he had heard her echoing laugh.
Even as he said this, he heard it again, and stealing toward him from out the corridor came a grey figure, laughing as she came. He gazed at it in wonder. It could not really be the Shadow Witch, he told himself. It must be that his eyes were deceiving him.
Impossible as it seemed, however, he presently saw that it was she who stood before him, knew that it was her own voice that rang clear and triumphant in his ears.
“The dungeon in which you thought to hold me was not strong enough when that day came of which I warned you, brother,” she declared. “By a power stronger than yours I have escaped, and I am here in proof that you have failed. In this place, as you well know, you can do naught against me.”
The Wizard’s eyes flashed fire. He made a step forward with hands outstretched to seize her. “Do not boast too soon,” retorted he. “I have yet a spell to conquer you even here.”
Although the Shadow Witch held her head high in defiance of him, she retreated a few paces. It was true, as she had said, that she was not afraid, but she did not mean to be without caution. She would make her test quickly. If she could but baffle him once more with that old trick of hers, that thus far had never failed to confound him, she would know that she was safe against him.
She waved her grey sleeves, and instantly there fell between her and the Wizard her magic curtain, her moving curtain of shadow. Before it stood a shadow image, so like to herself that it deceived even the keen eyes of the Wizard. Behind the curtain she herself was perfectly concealed.
It was done so quickly, so skilfully, that the Wizard did not guess what had happened. He snatched at the image but when he had almost grasped it, it withdrew from him swiftly. When he pursued it, it darted now to this side, now to that, with marvelous agility, always seeming just within reach of his fingers, yet always just eluding them as they began to close upon it, and each time he failed he heard the laughter that so mocked him.
A triumphant smile stole over the face of the Shadow Witch, for she saw plainly that she was still able to defend herself against him. Knowing how easily she could escape now from the Cave Hall with Prince Ember, she was about to beckon to him, but she was too late, for in that moment the Wizard snatched more swiftly than he had yet done at the gliding figure before the curtain, and this time not in vain. His hands closed upon it, indeed, but closed on nothingness, and thus he learned that he had once more been cheated by his sister’s art.
