For a long time the three men had been unconscious as the ship, with increasing acceleration, hurled itself toward Pluto. Duncan had carefully measured the Sherman units of the drug, calculating so that he would awaken hours before the others. But he forgot one thing—the terrific resistance _khlar_ builds up within the human body. So it was Rudy Hartman who first opened his eyes, groaned, and stared uncomprehendingly about him. He was strapped in a bunk, Duncan and Olcott near by. Memory came back. Sick and weak from the long period of catalepsy, Hartman nevertheless forced his aching limbs into motion. Staggering, he presently reached Duncan and took the latter’s gun. That done, he searched for a means of binding his captive securely. The bunk-straps were of flexible metal—not long enough, but they might serve a purpose. Hartman, scarcely conscious of his actions, fumbled at a panel and slid it back. Within the cubicle space-suits were stacked, each with its Varra Helmet, Olcott had ordered them removed when Hartman was repairing the vessel, but the scientist had not obeyed. He had not felt entirely certain that the cruiser would not be detected by the Plutonians, and perhaps he had felt a twinge of compunction at the thought of sending a helpless man to possible suicide, if his theory proved wrong. So he had concealed the Helmets behind a panel. Now he blessed the lucky chance that had made him do so. Duncan was still unconscious. Hartman rolled him out of the bunk and dressed him in a suit, fitting the Varra Helmet in place. With the flexible straps he bound Duncan’s arms to his side; a makeshift job, but it would serve. Finally he pried the intertron knob from the Helmet and sighed with relief. Hesitantly he went to the controls. The star-map told him little, except that they were approaching Pluto. Should they begin deceleration? Hartman’s fingers hovered over the studs—Damn! He dared not alter the course. He wasn’t a pilot, and it took trained hands to control a spaceship. Well, that didn’t matter. There was another way—with the Varra Helmets. * * * * * He broke an ammonia capsule under Olcott’s nose and applied artificial respiration. After a time Olcott stirred. “Hartman?” His tongue was thick. “Where—what’s happened?” “A great deal. Lie still and get back your strength. I’ll tell you—” But Olcott struggled to rise. “Duncan!” “He’s safe.” Hartman nodded toward the bound figure. Then he sucked in his breath and sprang up. Duncan’s eyes were open. “Stay where you are,” Hartman said, showing the gun. “I won’t hesitate to kill you, you know.” Duncan grinned. “Go ahead. You can’t pilot this ship. I can wait.” Olcott got up unsteadily. “You’ll pilot it—back to Earth. Damn you, Duncan—” “I’ll pilot it to Pluto. Nowhere else.” Hartman intervened. “Wait. Listen, Duncan. We have several Varra Helmets aboard. You didn’t know that.” “So what?”
