Mid Pleasures and Palaces

This planet was remote and set apart, and nothing about it had made William Kirk think he might find human life. Yet just beyond, through a thorny bush shaped like an exploding rose, Kirk had seen eyes and nose and a flash of yellow hair that were definitely human. Kirk poised motionless. He was three miles from the rocket and Leo, who was waiting inside of it. He thought for a moment of how Leo had told him, as they made their landing, that this is the kind of planet where you could go no further. This is the kind of planet that could be the end of twelve years, and you'd better be careful, William, old sport.
