Mark could hardly restrain his impatience. Behind that door was the solution of a great mystery--a mystery which had grown in importance beyond anything the Prison Bureau officials had dreamed of, Mark realized, considering the perilous super-efficiency of this spaceship, now speeding away from Venus! * * * * * Mark's name was called last, and he tried to achieve a careless nonchalance as he walked toward the door that opened silently for him. He would not have been too surprised to find that Aladdo was the Commander of this ship; that thought had occurred to him. As he entered the huge compartment, however, he had only a confused impression of brilliant lighting and indiscriminate luxury. Magnificent, ceiling-high tapestries covered the metal walls; beneath his feet, the resilient pile of an imperial Martian rug was a splash of varicolored splendour. Ornaments from three planets were everywhere, some of them museum pieces, like the desk of extinct Martian _Majagua_ wood, inlaid with miniature mosaics of semi-precious stones. "Loot from the spacelanes!" Mark exclaimed inwardly. And then he was beyond all amazement as his gaze went across the bright room, and he saw the two people present. One was Luhor, dressed resplendently now, the shadow of a smile upturning the corners of his mouth. He was standing. Seated at a desk beside him was a girl. She was clad in a close-fitting uniform of a white, gleaming material like watered silk. Mark slowly let out his breath, and then he crossed the room. He wondered if she were really that beautiful, or if it was just the garish lights and surroundings. She spoke first. "If you must be amazed, please do it quickly. I am weary of these interviews." Mark looked at her eyes that were blue but unsmiling, and lips that smiled thinly but didn't mean it. Her slightly turned-up nose would have been amusing ordinarily but wasn't now. Coppery brown hair was brushed smoothly back from her forehead, to fall in waves to her shoulders. Mark wished she would smile with her eyes as well as her lips. His own smile faded, he took a deep breath and said, "I am sufficiently amazed." "Good. Then we can proceed. Luhor, is this the last one?" "Yes. He's the one I was telling you about." She turned her cold blue eyes upon Mark again. Her voice was emotionless, almost a monotone. "Luhor tells me you were exceedingly anxious to leave the Venus swamp. Why?" "Why!" Mark repeated in amazement. "Why does any man want to leave there? It's a living death--and I was slowly going crazy." "You had only been there a few months?" "That's right." "Why were you sent there?" Mark hesitated for a split second, and decided he had better stick to the same story he'd told Aladdo. "I'm a 'political'," he said. She nodded, as though satisfied. "I have never been actually in the swamp. I understand that you worked hard there?" "Yes, very hard. We had to, to stay alive."
