Kueelo had whirled, muttering an oath that certainly wasn't Martian. Now he leaped for the free gun. Ric reached it a second faster, kicked it out of reach. He parried Kueelo's fist--then sent a left to the Martian's stomach and crossed with a right. The man was huge, and stood his ground. Ric danced back as Kueelo came boring in. He realized joyously that this lesser, artificial gravity was an advantage. He sent a boxer's left, long and weaving, to Kueelo's face, then a second and third, that set the Martian off balance. Ric stepped in with a crashing right-cross. Kueelo's legs went rubbery. Another smashing right and the Martian's face lost contour; he whirled half around and slumped across the bank of levers. Ric rolled his body away and stood looking down. There were thirty of those levers, all numbered. They were large and heavy, but just now they were all pulled up from their contacts, revealing masses of coils and wires. Ric frowned, wondering what it meant. He thought he knew! Those wires could be easily fused or cut. Ric recognized sabotage when he saw it.... He glanced at Kueelo. The man would be out for some time. He stepped to the one called Luhor, bent quickly over him. The man was dead, his skull crushed. Momentary panic flooded over Ric. After all, he could be wrong; if he'd blundered, he'd have to account for this! He rose, looked around for an inter-communication system. He couldn't spot one. This ship was utterly alien to him. He did find another door, however, and stepped out into a corridor. Ric gasped. This corridor extended for well over half a mile ahead of him, and as far behind--straight through the heart of the ship. This was a colossus indeed! Far ahead he could see a few men moving about, but if they noticed him at that distance they gave no sign of it. He started to walk in that direction, but a crisp voice stopped him. "Hold it, Earthman!" Something hard and heavy jabbed into his back. "You are very careless, Earthman. Your blow stunned me, but Martians recover easily. And you forgot to take the heat gun." Ric shot a glance over his shoulder. It was Kueelo all right, he of the colorless eyes. "Martian? Phobian half-breed, you mean! Those eyes--" "Never mind!" The gun jabbed harder. "No tricks with your hands this time, if you want to stay alive. Turn around--slowly! Let us march in the _other_ direction." * * * * * They walked along the empty corridor. Ric's mind was in turmoil. A half-breed aboard this ship was unthinkable! They passed strange, curved bulkheads abutting on the corridor. Ric couldn't understand them either. Everything about this ship was puzzling. "I'm really glad you came, Earthman. It makes my task easier!" "You mean--" "Yes. I shall leave the _Valiant_ to the Earth Fleet. But when that happens _we_ won't be there." He chuckled. "You don't understand? But you will--soon."
