The wine. The excitement. He dropped the wrench. "No, not yet!" he looked down at his chest, wildly tearing at it. "Not just yet, oh please!" he cried. "Not until I show them!" His heart went on beating, drunkenly, slowly. He bent, retrieved the wrench and laughed numbly. "I'll show 'em," he cried, weaving across the deck. "Show them how good I am. Eliminate competition! I'll run the ship myself!" He climbed slowly down the rungs to destroy the machines. It made a lot of noise. Nibley heard a shout. "Get him!" His hand went down again, again. There was a scream of whistles, a jarring of flung metal, a minor explosion. His hand went down again, the wrench in it. He felt himself cursing and pounding away. Something shattered. Men ran toward him. This was the computator! He hit upon it once more. Yes! Then he was caught up like an empty sack, smashed in the face by someone's fist, thrown to the deck. "Cut acceleration!" a voice cried far away. The ship slowed. Somebody kicked Nibley in the face. Blackness. Dark. Around and around down into darkness.... When he opened his eyes again people were talking: "We're turning back." "The hell we are. Kroll says we'll go on, anyway." "That's suicide! We can't hit that Asteroid Belt without radar." Nibley looked up from the floor. Kroll was there, over him, looking down at the old man. "I might have known," he said, over and over again. He wavered in Nibley's sobering vision. The ship hung motionless, silent. Through the ports, Nibley saw they were based on the sunward side of a large planetoid, waiting, shielded from most of the asteroid particles. "I'm sorry," said Nibley. "He's sorry." Kroll swore. "The very man we bring along as relief computator sabotages our machine! Hell!" Bruno was in the room. Nibley saw Bruno's eyes dilate at Kroll's exclamation. Bruno knew now. Nibley tried to get up. "We'll get through the Swarm, anyway. I'll take you through. That's why I broke that blasted contraption. I don't like competition. I can clear a path through them asteroids big enough to lug Luna through on Track Five!" "Who gave you the wine?"
