The wading giant had also gone that way. The messenger had said that Reaf was deserted, that giants were there. Evidently Reaf was the place at which these giants first appeared. Evidently it was the point of entrance and departure for them into and out of this realm. Leela and Frannie were being taken to Reaf. . . . Martt's heart leaped. An idea was forming in his mind. A plan--a mad, reckless plan. But it seemed possible of success. . . . He thought of the vehicle. It would be of no use against these giants. It was too unwieldy. Besides, shut up in it one could not attack. And when they stopped it to disembark, the giants would overwhelm it. Or, if at the moment it was too gigantic for them, then they would escape before the occupants of the vehicle could get out to stop them. . . . And besides, the vehicle was too precious--no chances like that should be taken with it. Martt told himself that he must get Brett to hide the vehicle. Guard it somehow. . . . A mad idea, this plan he was pondering. . . . They came to the lagoon-mouth; and here, to crystallize Martt's plan, to make it seem feasible--here lay a small sailboat, deserted by its owner. It lay, half pulled up on the sand, around the bend of the lagoon. "Zee! Stop! Wait! I want to talk to you." Zee had been bounding ahead of him. She stopped, waited, faced him. He was breathless. "That sailboat," he said. "It's one of the fast kind, isn't it?" "Yes." She regarded it. "Yes. Very fast." It was no more than a shell. A flat, spoon-shaped affair, with a small cockpit just large enough for two; and it had a very tall, flexible mast, and an overlarge crescent sail. The sail was flapping. Out on the lake the wind had risen. It was blowing directly toward Reaf. "Zee, listen--could you sail that boat?" "Oh, yes." "You could handle it in that wind out there?" "Yes. Of course." "And it would go--how fast, Zee?" "You mean--to Reaf?" She was as excited as he. "Yes. To Reaf. We could get there. Go after them. Cautiously. We could hide before we got there. I've a plan----" "How long to Reaf?" She pondered. "Three--what you call hours. We go fast in a wind like that." "Yes. That's it. Fast. Three hours. Zee, listen. Reaf must be where the giants go to leave for their own world. They're taking Frannie and Leela there. You see? And if we can get there--get into Reaf"--he gestured--"Zee, if they--those giants are very big, then we to them are small. Tiny. And it's quite dark. It would be dark in the caverns near Reaf--the houses there near the subterranean rivers. We would be so small the giants might not see us." He drew a long breath. "My plan, Zee, is to get in there, hide, and find a giant from whom we can steal the drugs. With the drugs----" She was trembling with excitement. No fear now. Reckless as only youth can be. "Oh Martt, if we could get the drugs! Brett said the giants must be using drugs. And make ourselves larger than the giants----"
