The men had stopped uncertainly, too weary and exhausted to understand. Then driven by a single thought, they staggered off to their building in search of water and food. Scarcely had the echoes of Mark's cry stopped reverberating, when from the shadows of a transverse corridor emerged the elfin figure of the Venusian. Aladdian gazed at Mark as if he had returned from the dead. She closed her eyes, swayed a little. Mark caught her in his arms. He too was silent. No words would serve. "To the palace!" she finally breathed, gently disengaging herself. Followed by Carston, they hurried to the imposing building where old George Marnik reigned. Aladdian led them swiftly through the panelled outer hall, through the magnificent salon where the loot from many years was a fabulous welter of wealth. Mark had no eyes for it now. They did not stop until they reached the inner chambers and finally came to George Marnik's room, where no one but Cynthia was ever permitted. * * * * * Lying grotesquely twisted on the priceless Martian tapestry that covered the bed, the ancient pirate was dead. Cynthia Marnik was kneeling beside him, weeping softly. There was no doubt as to the manner of his death. The pencil-thin opening through his temple could only have been done by an atom-blast. "Luhor," Aladdian said, indicating the wound with a gesture. They withdrew, leaving Cynthia alone with her grief. The two men followed the Venusian girl to the immense palace dining-room. With her own hands she served them food and drink, asking no questions, uttering no words until their vast hunger and thirst were appeased. Then she sat down. "And so," she began without preamble, "the unpredictable has entered." At their rush of questions she held up a hand. "Let me explain," she begged. "I can do it briefly if you are silent. After you left, Luhor ordered every man here to go aboard the Spacer. He blasted down two or three who refused; you will find them in the air-lock. Previous to that, I heard him arguing with George Marnik. He atom-blasted Marnik from behind. I know, because I deliberately contacted his mind, although the effort nearly drove me mad; it is not easy for us to tune to an alien intellect, but Luhor being partly Venusian helped." "The miracle is that he didn't take you with him," Carston ventured. "You were too valuable to leave behind!" "When we came here yesterday," she said simply, "I studied the plans of these caverns. When I learned what was in Luhor's mind, I hid in a maze of abandoned corridors. They searched for me a while, but since he plans to return, he gave up the search for the present. He had no time to waste! The Patrol has been to the Prison Swamp; failing to find either of you, and learning of my disappearance, _Earth has mobilized its fleet_!" "How--how do you know this?" Both men leaned tensely forward.
