DOUBLECROSS by JAMES Mac CREIGH Revolt was brewing on Venus, led by the descendant of the first Earthmen to land. Svan was the leader making the final There was no reason why everything shouldn't have been functioning themselves to Venus's climate. They're friendly enough." The Exec shrugged again. He stared at the wooden shacks that were the Venusian mist. The native guard of honor, posted a hundred yards from the Earth-ship, stood stolidly at attention with their old-fashioned proton-rifles slung over their backs. A few natives were gazing They think there will be hordes of immigrants from Earth, now that we know Venus is habitable. And there's some sort of a paltry underground group that is spreading the word that the immigrants will drive the native Venusians—the descendants of the first expedition, that is—right down into the mud. Well—" he laughed—"maybe they will. After all, the fittest survive. That's a basic law of—" The annunciator over the open lock clanged vigorously, and a metallic voice rasped: "Officer of the Deck! Post Number One! Instruments "Set up a screen! Notify the delegation! Alert a landing party!" But Svan clicked off the listening-machine and turned around. The five others in the room looked apprehensive. "You see?" Svan repeated. "From head. "Svan, I'm afraid," she said. "Who are we to decide if this Svan laughed harshly. " agreed.

There was a slow but unanimous gesture of "Good," said Svan. "Then we must act. The Council has told us that we alone will decide our course of action. We have agreed that, if the Earth-ship returns, it means disaster for Venus. Therefore, it must not return." An old man shifted restlessly. "But they are strong, Svan," he Svan nodded. "No. They will leave. But they will never get back to "Never get back to Earth?" the old man gasped. "Has the Council Svan shrugged. "The Council did not know what we would face. The Earth-ship has." He paused dangerously. "Toller," he said, "do you Svan smiled, and it was like a dark flame. He reached to a box at his ship.

"Ingra, bring me that Silently the girl picked up an opaque glass bowl from the broad arm of her chair. It had held Venus-tobacco cigarettes there were a few left. She shook them out and handed the bowl to Svan, who was rapidly and held it without opening it. The bowl went the rounds, till Svan himself took the last. All eyes were on him. No one had looked at their Svan, too, had left his unopened. He sat at the table, facing them. guards will be called. There will be commotion—that is easy enough, after all from the sun to return—in forty hours the danger is removed." There was comprehension in their eyes, Svan saw ... but still that Though he had willed his eyes away from it, his fingers had rebelled. striving to detect if it was the fatal one. They had felt nothing.... up now, around at his neighbors. Svan waited impatiently for the chosen Svan thought faster than ever before in his life. If there was a of a second, Svan had considered the evidence and reached his decision. In the palm of his hand, Svan held up the slip he had just marked in The six conspirators in Svan's old ground car moved slowly along the main street of the native town. Two Earth-ship sailors, unarmed except "Good," said Svan, observing them. "The delegation is still here. We The right answer leaped up at him. jungle that surrounded them. Svan noticed it was raining a little. The that followed its thunderous crash, a man's voice bellowed: "Halt!" The girl, Ingra, gasped something indistinguishable, slammed on the brakes. A Venusian in the trappings of the State Guard advanced on them from the side of the road, proton-rifle held ready to fire again. "Where are you going?" he growled. Svan spoke up. "We want to look at the Earth-ship," he said. He opened Svan stepped closer, his teeth bared in what passed for a smile. "It He strove instinctively to bring the clumsy rifle up, but Svan was faster. His gamble had failed there was only one course remaining. He hurled his gross white bulk at the guard, bowled him over against the splintery logs of the road. The proton-rifle went flying, and Svan savagely tore at the throat of the guard. Knees, elbows and claw-like nails—Svan battered at the astonished man with every ounce of strength in his body. The guard was as big as Svan, but Svan had the initial advantage ... and it was only a matter of seconds before the guard lay unconscious, his skull a mass of gore at the back where Svan had Svan grunted as his fingers constricted brutally. Svan rose, panting, stared around. No one else was in sight, save the petrified five and the ground car. Svan glared at them contemptuously, then reached down and heaved on the senseless body of the guard. Over jungle. Even while Svan watched the body began to sink. There would be Svan strode back to the car. "Hurry up," he gasped to the girl. "Now there is danger for all of us, if they discover he is missing. And keep a watch for other guards."

Remember, you are in no danger from the guards." From the guards , his mind echoed. He smiled. At least, they would feel no pain, never know what happened. With the amount of atomite in "Svan." The girl, Ingra, leaned over to him. Impulsively she reached for him, kissed him. "Good luck to you, Svan," she said. Svan looked after them. The kiss had surprised him. What did it mean? Was it an error that the girl should die with the others? its own fierce rockets. Svan's mist-trained eyes spotted the circling slim-shafted blasters they carried.
