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."

Everybody turned around to see who else had entered the conversation. It
was Hansen. "I'm going to give you fifteen minutes, not thirty," Hansen
said. "Then I'm going to turn the grid power on at full intensity. You can
either use it to take off, or sit around and roast alive inside your ship."
Candle turned and looked at Hansen with new respect. "Okay ... Let's go
back to your place. I've still got some things to figure out."

Quemos was on the verge of hysteria. "You're bluffing! You wouldn't dare.
I'll report this!"

Fifteen minutes later, the ship headed for space.
