It's not so much the decisions a man does make that mark him as a Man—but the ones he refrains from making. Like the decision "I've had enough!" Illustrated by Schoenherr Read locked the door and drew his pistol. Sergeant Rashid handed Premier Umluana the warrant. If Umluana noticed Read's gun, he didn't show it. He read the you'll excuse me, I must return to my party." In the other room people laughed and talked. Glasses clinked in the late afternoon. Read knew two armed men stood just outside the door. "If you leave, Premier, I'll have to shoot you." Read clicked off the safety. "Corporal Read is very young," Rashid said, "but he's a crack shot. That's why I brought him with me. I think he " Rashid judo chopped him and swung the inert body over his shoulders. Read pulled a flat grenade from his vest pocket. He dropped it and yellow psycho gas hissed from the valve. catatonic trance. A little car skimmed across the lawn. Bearing the Scourge of Africa, Rashid struggled toward it. Read walked backward, covering their retreat. grenades. "I better cover," he said. "Thanks," Rashid said. The inspector slid out of the car and ran to a clump of bushes. The driver pushed in the accelerator. As they swerved toward the south, Read saw a dozen armed men run out of the house. A grenade arced from the bushes and the pursuers recoiled from the cloud that rose before them. pocket. "Well, Read, it looks like we're in for a fight. In a few minutes Miaka Station will know we're coming. And God knows what will happen at the Game Preserve." Read wanted to jump out of the car. He could die any minute. But he had set his life on a well-oiled track and he couldn't get off until they reached Geneva. He had belonged to a gang called The Golden Spacemen. "Nobody fools with me," he bragged. "When Harry Read's out, there's a tiger running loose." No one knew how many times he nearly ran from other clubs, how carefully he picked the safest spot on the international cops wore green berets, high buttonless boots, bush But the evidence was clear. Umluana was defying world law. If he "One thing," Read said, "I don't think they'll shoot at us while he's in the car." Read looked back. He saw three spots of sunlight about two hundred feet up and a good mile behind. "Shall I duck under the trees?" the driver asked. "Not yet. Not until we have to." Read fingered the machine gun he had picked up when he got in the car. He had never been shot at. Twice he had faced an unarmed mob, but a few shots had sent them running. "Evade," Rashid said. "Don't go down." Without losing any forward speed, the driver took them straight up. Read's stomach bounced. A shell exploded above them. The car rocked. He raised his eyes Read copied him. Umluana breathed like a furnace, still unconscious from the injection Rashid had given him. I can't do anything , Read thought. "Can't we go down?" Read said. "They'll get to Miaka before us." He shut his eyes when he heard another loud explosion. slowed down, then crashed through the glass walls and hovered by the transmitter booth. Rashid opened the door and threw out two grenades. Read jumped out and the two of them struggled toward the booth with Umluana. All three panicked when the psycho gas enveloped them. They ran howling for the jungle. Through the window of his mask, Read saw their pursuers land in the clearing. Machine-gun bullets raked the building. They got Umluana in the booth and hit the floor. Read took aim and opened waiting room surrounded the bank of transmitter booths. Read looked out the door and saw his first battlefield. Directly in front of him, his head shattered by a bullet, a dead inspector lay behind an overturned couch. Read had seen dozens of training films taken during actual Now he slid against the rear wall of the transmitter booth. A wounded inspector crawled across the floor to the booth. Read "Did you get Umluana?" he asked Sergeant Rashid. eighteenth year he had done everything his superiors told him to do. He started crawling toward an easy-chair that looked like good cover. A bullet cracked above his head, so close he felt the shock wave. He got up, ran panicky, crouched, and dove behind the chair. "I'm calling South Africa Station for a copter. It's the only way out of here. Until it comes, we've got to hold them back." Read thought of the green beret he had stuffed in his pocket that morning. He stuck it on his head and cocked it. He didn't need plain clothes anymore and he wanted to wear at least a part of his uniform. The machine gun kicked and chattered on his shoulder. He picked a target and squeezed off a burst. Tensely, he hunted for another Read surveyed his sector of fire. About two hundred yards to his left, he saw the top of a small ditch. Using the ditch for cover, his vest pocket. He opened it and a pair of sights flipped up. A thin track ran down one side. He had about a dozen grenades left, three self-propelling. He ditch. He dropped another grenade beside it. The heavy gas would lie there for hours. "The copter will be here in half an hour. We'll put Umluana on, Rashid ran off. Read stared across the green land and listened to the pound of his heart. What were the Belderkans planning? A mass frontal attack? To sneak in over the top of the hill? He didn't think, anymore than a rabbit thinks when it lies hiding from the fox or a panther thinks when it crouches on a branch above the trail. His skin tightened and relaxed on his body. burned, or cut up by shrapnel, or gassed with some new mist their masks couldn't filter. Read shut his eyes. All around him he heard heavy breathing, mumbled comments, curses. Clothes rustled as men moved restlessly. something more than a hunger for self-respect. Read had seen the inspector who covered their getaway. He had watched their escort charge three-to-one odds. He had seen another inspector stay behind at Miaka Station. And here, in this thirty-foot intervals along the floor. "Remember," Rashid said. "We have to knock out that gun." Read had given away his machine gun. He held a gas-filled bottle in each hand. His automatic nestled in its shoulder holster. Rashid whistled. Dozens of smoke grenades tumbled through the air. Thick mist engulfed the tank. Read stood up and ran forward. He crouched but didn't zigzag. Speed counted most here. "Read, you've got to. I think you're the only—" "What?" Guns clattered. Bullets cracked. decided something in the world was more important than himself, but he didn't know it or realize the psychologists would be surprised to see him do this. He had made many decisions in the last few minutes. He had ceased to think about them or anything else. With his cigarette lighter, he lit the rag stuffed in the end of the bottle. Biting his tongue, he pulled himself up the front of the tank. His long arm stretched for the muzzle of the gun. He tossed the the neck. He didn't feel them. He had fainted the moment he felt the bottle leave his hand. The copter landed ten minutes later. Umluana left in a shower of
