He stopped to set in the coordinates of the Moon for the robot pilot, but he found himself still wanting to talk. "Man has reached space--do you think he'll ever go back to the ground? In space he has gravity only when he wants it, and any weight of gravity he likes, depending on how fast he spins his house. And no gravity when he wants that. You see what that means to engineers in the advantage of building things? No weight in transportation, no weight in travel, limitless speed and almost no cost as long as he stays away from planet pulls. His house is in the sky, and when he steps out of it he can fly like a bird. And food. To grow food there is sunlight Earth never dreamed of. For heat and power there is sunlight to focus. Space is flooded with heat, irradiated with power-- "It's not child's play taming it, and those on the ground don't see it yet. But the next step of mankind is out into space, and it's never coming back." Pierce, sitting in one of the shock tank armchairs, asked, "What part do you have in this?" Bryce looked at him with a feeling almost of surprise, as if he had been called back from a long distance. "Me?" he laughed, a little awed by the immensity of the goal, and the ease of it.... "First President of the Belt and political boss for life. That's enough." Enough to hold the solar system in the palm of his hand, if he chose. He who rules space, rules the planets. It was the first time he had ever mentioned his goal to anyone. Roy Pierce asked, "What do I do about this 'friend' of yours who lays traps?" The last attack had settled the question of who was behind the other attacks, and who had told Beldman, but Orillo would still be a useful pawn. All that was necessary was to evade his attempts at murder for a month or so until partnership tied them too close for murder. Bryce explained some of that to Pierce, setting up a chess board to pass away the time until they arrived back at Moonbase City. "What's my next assignment?" Pierce asked, when they were several moves into the game. Bryce recalled a danger he had made no move to guard against. "The Board hired a psychologist, a mind hunter, to find out who's doing the undermining. He's one of the Manoba group. Remember the name, look it up and find out what their methods are, how to recognize them, and report back what to do about it." "I'll take care of him," Roy Pierce said absently, moving his knight to threaten Bryce's bishop. "No unnecessary trouble. Remember I have to keep my name clean." Bryce moved a pawn one step to cover the bishop and leave room for his other bishop to menace the knight. "I'll be careful. There'll be no publicity. He won't get hurt," Pierce said, moving the knight into Bryce's second line where it threatened the king and a cornered castle. "Check." And he added, as if apologizing for having delayed his move, "I don't like to move until I'm sure what's going on."
