plane on the scanner. A sleek projectile was rocketing along after the camera cruiser. “Oh, that’s Speedy,” Quade said. “One of the Zonals. He won’t follow us long.” But this proved inaccurate. Speedy stayed on the trail for twenty miles before he was lost in the distance. Then nothing was visible but the frigid, Cyclopean peaks of the Devil’s Range, icy and alien in the pale light of Saturn. Things began to happen with alarming suddenness. There are plenty of safety devices on spacecraft, but these depend on the assurance that you have a skilful and a conscious operator. Quade was skilful enough, but unfortunately he was knocked cold when the vessel sideslipped in a sudden blast of air, powerful as a cyclone, that screamed up from the Devil’s Range. A geyser-heated valley below made a thermal of racing air that created a maelstrom where the icy atmosphere of Titan met it. The camera cruiser turned sidewise and Quade went spinning into the controls. His head banged against his helmet, which made him lose all interest in the fact that the ship was plunging down. Kathleen couldn’t do much about it, though she tried hard enough. She was wedged under a tangle of apparatus, which imprisoned her but saved her from serious injury when the ship struck, with a splash that sent water leaping high. Creamy, luminous liquid crept over the ship’s nose. An oddly-shaped fish came to stare in pop-eyed amazement. Then it swam hastily away. The ship grounded. Kathleen fought her way free and scrambled up the tilted floor to where Quade lay. There was blood oozing from his head, and Kathleen quickly removed the helmet and used the first-aid kit. But Quade remained stubbornly unconscious. Two courses were left. Kathleen could fly the ship back to the camp or she could radio for help. She tried both, but without success. The controls were smashed, the gravity plates warped and broken. The cruiser’s day of usefulness was over. The radio was hash. A telephoto camera was strewn in sections about the room and some of the carboys of concentrate-dye had torn free from their moorings and were broken. The floor was awash with yellow and pink fluid. Kathleen peered up through the ship’s nose. The surface of the lake beneath which they lay wasn’t far above, she judged. If she could swim
