There was a long silence. Then he said, as though there had been no silence, "Of course I don't. I think you dance beautifully." And he added, "It made me----" His tongue was about to say, "It made me love you," but his beating heart smothered the words. He amended, "It made me think that your father was very wrong to say that. And about Leela, too." At the mention of Leela he saw a shadow cross Zee's face. He tensed himself; set his jaw grimly. This was no time for thoughts of love. Leela, and his sister Frannie, were captured by giants. There was work, danger for him and for Zee, up ahead in this starlit night. He would need all his wits, all his resourcefulness. . . . He remembered the one visit he had formerly made to Reaf; tried to recall how the city lay. Tried to plan what he and Zee would do, now when they got there. He said, "Zee, the rivers at Reaf that plunge into the mountains--no one has been in them very far?" "No," she said. "Can you walk along their banks, inside, under the mountains?" She nodded. "In some places there are narrow ledges beside the water. But how far--no one knows." "And in other places--near Reaf, I mean--there are tunnels? Passageways?" "Yes. Back into the caves and beyond." "I think," he said, "that back through there is the way to the giants' huge outer world. They've come down, and through the ground behind the mountains. Do you suppose they'll take Leela and Frannie up to their own realm? Or keep them in Reaf?" "I think--we do not know anything about it," she said. He smiled grimly. "You're right, we don't. Why the giants should come here at all I don't know. But we're going to know more about it before we get through with them, Zee. What I'm hoping is that we might find one of them alone. We've got to get the drugs away from them somehow. We've got to." Martt remembered once arguing with Brett about the giants. Brett had thought that they used some drug--two drugs--one to shrink proportionately each of their body cells, and the other similarly to increase the size of the cells. Drugs of the kind had already been sought for on Earth. Nitrogen was the basis for growth. And the new element, Parogen, had been found to cause a shrinkage. In Mars they had developed such drugs further--but they were still impractical for human use. These giants evidently had something of the kind. And it must be radio-active--it must cause a radiation affecting vegetable or animal matter in near proximity to the changing body. The garments of the giants expanded and contracted with their bodies. But Brett had said that a weapon in your hand--particularly one of mineral--would not change size. . . . The thought was to some slight degree, at least, comforting to Martt; the giants would be unarmed. Zee's voice broke in on his thoughts. "Look, there are the mountains behind Reaf."
