"He has a theory about everything. I think what he was trying to convey was that this--this levitation confirmed his magnology principle." "What's that?" Don asked. "I haven't the faintest idea. I'm a politician, not a scientist. Professor Garet went on about it for a while, on the telephone, about magnetism and gravity, but I think he was only calling as a courtesy, so the mayor wouldn't look foolish the next morning, not knowing his town had flown the coop." "What's the population of Superior?" "Three thousand, including the students at the institute. Three thousand and forty, counting you people from the train. I guess you'll be with us for a while." "What do you mean by that?" Jen Jervis asked. "Well, I don't see how you can get down. Do you?" "Does Superior have an airport?" Don asked. "I've got to get back to--to Earth." It sounded odd to put it that way. "Nope," Civek said. "No airport. No place for a plane to land, either." "Maybe not a plane," Don said, "but a helicopter could land just about anywhere." "No helicopters here, either." "Maybe not. But I'll bet they're swarming all over you by morning." "Hm," said Hector Civek. Don couldn't quite catch his expression in the rearview mirror. "I suppose they could, at that. Well, here's Cavalier. You go right in that door, where the others are going. There's Professor Garet. I've got to see him--excuse me." The mayor was off across the campus. Don looked at Geneva Jervis, who was frowning. "Are you thinking," he asked, "that Mayor Civek was perhaps just a little less than completely honest with us?" "I'm thinking," she said, "that I should have stayed with Aunt Hattie another night, then taken a plane to Washington." "Washington?" Don said. "That's where I'm going. I mean where I _was_ going before Superior became airborne. What do you do in Washington, Miss Jervis?" "I work for the Government. Doesn't everybody?" "Not everybody. Me, for instance." "No?" she said. "Judging by that satchel you're handcuffed to, I'd have thought you were a courier for the Pentagon. Or maybe State." He laughed quickly and loudly because she was getting uncomfortably close. "Oh, no. Nothing so glamorous. I'm a messenger for the Riggs National Bank, that's all. Where do you work?" "I'm with Senator Bobby Thebold, S.O.B." Don laughed again. "He sure is." "_Mister_ Cort!" she said, annoyed. "You know as well as I do that S.O.B. stands for Senate Office Building. I'm his secretary." "I'm sorry. We'd better get out and find a place to sleep. It's getting late." "_Places_ to sleep," she corrected. She looked angry. "Of course," Don said, puzzled by her emphasis. "Come on. Where they put you, you'll probably be surrounded by co-eds, even if I could get out of this cuff."
