Extensive research did not uncover any evidence that the U.S. copyright on this publication was renewed. THE decision "I've had enough!" Premier Umluana the warrant. If Umluana noticed Read's gun, he didn't show it. He read the "Then I'll speak English." Umluana was a small man with wrinkled brow, glasses and a mustache. His skin was a shade lighter than Read's. "The Inspector General doesn't have the power to arrest a head of state—especially the Premier of Belderkan. Now, if you'll excuse me, I must return to my party." "I don't think so," Umluana said. "No, if you kill me, all Africa Umluana turned back to Rashid a second too soon. He saw the "Help! "They'll be after us in half a minute." 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." "They don't know who's coming," he said. "They don't make them home of factory workers, clerks, semiskilled technicians, all who do the drudge work of civilization and know they will never do more. The adults spent their days with television, alcohol and drugs sleep so much? I don't want to be like that. I want to be The UN Inspector Corps had been founded to enforce the Nuclear One power implied in the UN Charter no Secretary General or Inspector General had ever tried to use. The power to arrest any head of state whose country violated international law. Could the civil war. Men planted bases on the moon and in four years, but the black population of Africa still struggled toward political equality. Umluana took control of Belderkan in 1979. The tiny, former Dutch colony, had been a tottering democracy for ten years. The very day he took control the new dictator and his African party began to build up the Belderkan Army. For years he had preached a new Africa, united, free of white masters, the home of a vigorous and true freedom for their people. But the radio assault and the arms buildup continued. Early in 1982, South Africa claimed the Belderkan Army exceeded the size agreed to in the Disarmament Treaty. The European countries and some African nations joined in the accusation. China called the investigation by the UN. But the evidence was clear. Umluana was defying world law. If he got away with it, some larger and more dangerous nation might follow his precedent. And the arms race would begin again. The Inspector General decided. They would enter Belderkan, arrest Umluana and try him by due process before the World Court. If the plan succeeded, mankind would be a long step farther from nuclear Belderkan fighters in hot pursuit, other nations joining the chase and the world uproar gaining volume. By transmitter, if all went well, they could have Umluana in Geneva in an hour. They were racing toward Miaka, a branch transmitter station. From Miaka they would transmit to the Belderkan Preserve, a famous tourist attraction whose station could transmit to any point on the globe. Even now a dozen inspectors were taking over the Game Preserve station and manning its controls. They had made no plans to take over Miaka. They planned to get there before it could be defended. "There's no military base near Miaka," Rashid said. "We might get there before the Belderkans." alike. I'll bet Umluana's lieutenants are hoping he'll become a "Not yet. Not until we have to." surrounded each vehicle. The escort car made a sharp turn and charged their pursuers. The big rifle fired twice. Read saw the Belderkan cars scatter. Read copied him. Umluana breathed like a furnace, still I can't do anything They're too far away to shoot back. All we can do is run. "Can't we go down?" Read said. "They'll get to Miaka before us." The station was a glass diamond in a small clearing. The driver slowed down, then crashed through the glass walls and hovered by out and the two of them struggled toward the booth with Umluana. The driver, pistol in hand, ran for the control panel. There were three technicians in the station and no passengers. All three panicked when the psycho gas enveloped them. They ran howling for the jungle. Umluana in the booth and hit the floor. Read took aim and opened Preserve. The station jutted from the side of a hill. A glass-walled waiting room surrounded the bank of transmitter booths. Read inspector lay behind an overturned couch. Read had seen dozens of training films taken during actual "Did you get Umluana?" he asked Sergeant Rashid. think half our men are wounded." "Can we get out of here?" "They machine-gunned the controls." Rashid swore. "You heard him, Read! Get out there and help those "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." inspectors fired a long, noisy volley. When they stopped only The attackers had come straight up a road that led from the Game Preserve to the station. They had not expected any resistance. The UN men had already taken over the station, chased out the passengers and technicians and taken up defense positions they had met the Belderkans with a dozen grenades and sent them scurrying for cover. The fight so far had been vicious but disorganized. But the Belderkans had a few hundred men and knew they had wrecked the transmitter controls. The first direct attack had been repulsed. They could attack many more times and continue to spray the building with bullets. They The inspectors had taken up good defensive positions. In spite of their losses, they still had enough firepower to cover the area surrounding the station. 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, the Belderkans could sneak to the top of the hill. Gas grenades are only three inches long. They hold cubic yards of gas under high pressure. Read unclipped a telescoping rod from The heavy gas would lie there for hours. "The copter will be here in half an hour. We'll put Umluana on, surrender." "We'll stop them, Sarge. Don't worry." 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? ALL GASES, ROCKETS AND FLAME THROWERS. IF YOU DO NOT SURRENDER OUR PREMIER, WE WILL DESTROY YOU. "They know we don't have any big weapons," Read said. "They know we have only gas grenades and small arms." masks couldn't filter. "We've got to knock that thing out before the copter comes. enough for the UN Umluana. Read, the Frenchman and himself, he stationed at engulfed the tank. Read stood up and ran forward. He crouched but didn't zigzag. Speed counted most here. Gunfire shook the hill. The Belderkans couldn't see them but they knew what was going on and they fired systematically into the smoke. "I can't move, Sarge." "Read, you've got to. I think you're the only—" The copter landed ten minutes later. Umluana left in a shower of bullets. A Russian private, the ranking man alive in the station, surrendered the survivors to the Belderkans. His mother hung the Global Medal above the television set. "He must have been brave," she said. "We had a fine son."
