"You remember our bargain?" he asked curtly through the space-phones. Marshall shook a leathern pack of documents in his metal-gloved hand. "I remember," he muttered hoarsely. "And if Alyce is completely recovered, as you say she is, I will sign every space-liner I own over to you." "Very well," said Rufus Thallin. "Follow me." He led them down a curving corridor carved from solid volcanic rock, and at length emerged into a gigantic cavern. The floor of the cavern ended abruptly in a ledge that fell sheer into black depths.

"If only you'd think more of science, and not of—" Rufus Thallin was no longer listening. He had whirled around and was peering into the indigo blackness of the cavern from which they had come. "My nerves," he said
