“No more welding,” Sally told him. “Not on this job. The Platform’s closed in. They’ve started to take down the scaffolding.”

The Chief looked startled. Haney asked: “Laying off men yet?”

“Not you,” Sally assured him. “Definitely not you. You four have the very top super-special security rating there is! I think you’re the only four people in the world my father is sure can’t be reached, somehow, to make you harm the Platform.”

Mike said abruptly: “Yeah. The Major thought he had headaches before. Now he’s really got ’em!”

Mike hadn’t seemed to be listening. He’d acted as if he were feverishly absorbing the feel of being inside the Platform—not as a workman building it, but as a man whose proper habitat it would become. But Joe suddenly realized that his comment was exact. There’d been plenty of sabotage to prevent the Platform from reaching completion. But now it was ready to take off in two days. If it was to be stopped, it would have to be stopped within forty-eight hours by people with plenty of resources, who for their own evil ends needed it to be stopped. These last two days would contain the last-ditch, most desperate, most completely ruthless stepped-up attempts at destruction that could possibly be made. And Major Holt had to handle them.

But the four at table—five, with Sally—were peculiarly relaxed. The matter they’d handled had been conspicuous, perhaps, but it was still only one of thousands that had to be accomplished before the Platform could take off. But they had the infinitely restful feeling of a job well done.

“No more welding,” said Haney meditatively, “and our job on the gyros finished. What are we gonna do?”

The Chief said forcefully: “Me, I’m gonna sweep floors or something, but I’m sure gonna stick around and watch the take-off!”

Joe said nothing. He looked at Sally. She became very busy, making certain the others did not want more to eat. After a long time Joe said, with very careful casualness, “Come to think of it, I was getting loaded up with astrogation theory when I had to stop and pitch in on the gyros. How’s that sick crew member, Sally?”

“I—wouldn’t know,” answered Sally unconvincingly. “Have some more coffee?”
