Of course, he thought, there were plenty of women upon Earth and her star-colonies who didn't share his culture, even if they'd been brought up in it. But their case was simply a matter of taste. And they could still share a certain amount with him, just because they'd breathed the same atmosphere and talked the same words as he. Not that he would have cared to live with them, because he wouldn't. But Amra, desirable in so many ways, just would not understand what was taking place around her or in the minds of those she would have to live with. He looked down at Amra. Her back was turned, and she seemed to be breathing the easy breath of deep sleep. Though he doubted very much that she could be sleeping, he decided to accept things as they looked. He wouldn't answer her now, though he knew that when morning came her eyes would be asking the same question, even if she didn't voice it. At least, he thought, she'd been diverted from her curiosity about what he'd been doing that night. That was something. He didn't want anybody to know about that. Not until the time for action came. Provided, that is, that he could do anything even then. He'd discovered certain things tonight that could mean his salvation if he could utilize them. That was the rub, as some poet or other had once said. Wondering just who had originated that saying, he fell asleep. Woolgathering had always been a favorite occupation of his when people left him alone to do it. That was the rub. They didn't. 25 Shortly after dawn the yacht set sail and sped toward Estorya, a hundred miles west. The breeze was a strong thirty-five miles an hour, precursor of the violent winds that roared across the Xurdimur during the rainy season. Green set every inch of sail he had and took over the helm himself. Steering was not as simple as it had been, for traffic was getting heavy. In an hour he saw no less than forty 'rollers, ranging in size from small merchants not much larger than his own craft to tremendous three-decker 'rollers-of-the-line from far-off Batrim, convoying even larger merchant vessels, high-pooped and richly decorated. Then, as they came to within fifty miles of their destination, small pleasure yachts appeared in increasing numbers. And by the time they saw the white rocket-shaped towers that stretched from horizon to horizon, Green was sweating at the manner in which craft were shooting back and forth in front of him. Miran said, "The entire nation is surrounded by these white towers and by many fortresses interspersed between them. Inside the great circle of towers the Estoryans have many rich farms on the plains. The city proper, however, is built on three roaming islands that were captured by their magic many centuries ago." Green raised his eyebrows at this information. "Indeed? And where is the vessel that brought the two demons down from the skies?"
