Hansen cut the communicator off. He stood there for a moment, feeling depressed and betrayed. Automatically he reached down and flicked imaginary dust from his blue sleeve with its narrow solitary gold band. Ten minutes later the Gypsy's ship signaled for landing. The man who walked into Hansen's control room was hardly the ogre he had been prepared for. He looked, Hansen was later to reflect, like Santa Claus with muscles in place of the fat. Wearing an almost unheard of beard and dressed in rough clothes, he walked across the room and made short work of the usual formalities. "Name's Candle," said the man. "Where's those two phonies I'm supposed to replace?" "You'll have to go suit up and go back through the airlock," Hansen said, motioning to the door. "They're in their ship. It's the one next to yours. Want me to tell them you're on your way over?" "Hell, no," said Candle, grinning, "I'll surprise 'em. Now, suppose you and me sit down and have a little chat." They sat and Candle pumped Hansen of everything he knew about the entire situation. An hour later, Hansen felt almost as if he had been had. "Is that all?" he asked, wearily. "I got the facts," Candle said. "Now let's go throw those experts out." It wasn't quite that simple. Neither Bullard nor Quemos had any intention of simply clearing out. "Who the hell you think you are," Bullard said, "to come over here and order us off? We didn't even ask for help. And, God knows, you couldn't supply it anyway." Bullard, with evident distaste, ran his eyes up and down Candle's clothing. Dr. Quemos had some ideas, too. "Letter of authority or no letter of authority," Quemos said, pointing a manicured forefinger at the paper in Candle's hand, "you'll ruin everything! You have no idea what you're up against. We've spent weeks working this thing out--" Candle grinned. "What've you worked out?" "Why--why we know that this is a metal double enveloping worm gear." "Wrong," Candle said. "It's a single enveloping worm gear. It's made of steel with an aluminum alloy wheel gear and the two parts have corroded and stuck. The whole mechanism was originally designed for submarines." Quemos started to say something, then turned and looked at Bullard for reassurance. "He's crazy," Bullard said, "he's making it up as he goes along. How could he possibly know what he's talking about? Why, there haven't been any submarines for centuries." "I'm tired of playing games," Candle said, no longer grinning. "The boy and I have work to do. You two are in the way. You'll only take up time if I have to work with you and show you what to do. I want you and your ship out of here in half an hour." "Who's going to make us?" Bullard asked with great originality. "I am."
