* * * * * His probing eyes went thoughtfully over the poor cowering wretch. Those careworn features were familiar, somehow. Where had he seen the man before? Suddenly he stiffened, choking an exclamation. The man was bound immovably to his seat. Thin metal links, almost invisible, encircled his feet; held the elbows taut against the fluted columns of the seat-back. Hilary's space-tanned features hardened; the light gray of his eyes darkened. All the pleasure of his homecoming vanished. The kindly Earth seemed suddenly grown inimical. What had happened in the five long years of his absence? This would have been impossible on the Earth he had known; a man, manifestly the victim of hideous tortures, bound like a wild animal to the seat of a public conveyor. He went swiftly into action. From the depths of a capacious pocket he fished a sheathed blade of stellite, triply keen; its razor-sharp edge sawed smoothly at the bonds. In his mounting anger Hilary had paid no attention to the scattering of people occupying the cushioned chairs of the speeding conveyor. But a smothered nearby gasp caused his head to jerk up. He met the incredulous stare of a paunchy, heavy-jowled man seated some chairs away. There was more than incredulity, there was furtive fear in the small beady eyes sunken in folds of fat. Hilary gave way to unreasoning anger. "Stop looking like a stuck pig," he called sharply. "Give me a hand with this poor fellow." The response was surprising. The man got up from his chair precipitately, stark panic written all over him. The sweat oozed from his shiny forehead as he backed cautiously away. He tripped over the edge of the seat behind, and fell. Once more he scrambled to his feet, and as if the fall had released his trembling muscles, he turned and ran, stumbling and dodging across the local conveyors, never once looking back. * * * * * Hilary watched his mad flight wonderingly. "Good Lord," he thought, "does my face frighten people so? Maybe I've turned into a Martian." He turned to appeal to the others on the conveyor, and received another shock. The few men within earshot were already on their feet and moving away from there with unostentatious celerity. Hilary surveyed their receding backs thoughtfully. What was there about himself to frighten grown men out of their wits? Or was it the poor tortured wretch he was trying to release who was responsible for the exodus? Already the express was almost clear. He saw the deserters throwing themselves guiltily into seats on the local belts, and then he was carried swiftly past. Only one man remained stubbornly in his seat, some fifteen rows back. He was a huge mountain of a man, a giant upon Earth, and there was a strangeness in his wide stare.
