TOLLIVER'S ORBIT Betty frowned at him. Koslow Spaceways, glowered back at him. Its reddish tinge brightened "You asked any of them lately?" Tolliver prodded. They know what it's like. D'ya think they Tolliver stared at him silently, but the other had difficulty meeting "Doesn't matter," answered Tolliver, grinning amiably. "The hazardous Tolliver began to have his doubts the next day On the bulletin board, Tolliver's name stood out beside the number that it was payday was small consolation. "Hey, Johnny!" said a voice at his shoulder. "The word is that they're finally gonna trust you to take that creeper outside." Tolliver turned to see Red Higgins, a regular driver. "What do you mean?" Later in the day-period, Tolliver recalled this warning. Under a Tolliver. "By the way, just call me Betty." or does he just know where bodies are buried? "They were making dates," said the girl. "Were they ribbing me, or is it true that none of the four of them goes back with the ship?" He followed the signals of a spacesuited member of the port staff and "What did you expect?" asked Tolliver. "Square dances with champagne?" this creeper, I'm entitled to some amusement. And Daddy's little girl is trying too hard to sound like one of the gang. Tolliver pursed his lips and put on a shrewd expression. "You can call me Betty. What happened to him?" Tolliver! Tolliver, driver of "missions" across the menacing wastes between dome he was drawing the salary of a space pilot. Betty looked thoughtful. as if with a burden of worry upon her mind, and the pilot's conscience know better. Remembering his grudge against the manager, he took pleasure in walking in without knocking. "Jeffers," he announced, "this is ... just call her Betty." "Miss Koslow!" he beamed, like a politician the day before the voting. Tolliver, you can go. Yes, indeed! Mr. Koslow—the president, that is: your father—sent a message about you. I repeat, it will be an honor to show you the ropes. Did you want something else, Tolliver?" "Never mind him, Mr. Jeffers," snapped the girl, in a tone new to Tolliver. "We won't be working together, I'm afraid. You've already had enough rope." pilot stared at Betty, trying to recall pictures he had seen of the told en route from the spaceport. "Wh-wh-what do you mean, Miss Koslow?" Jeffers stammered. He darted a suspicious glare at Tolliver. I was not allowed to reach twenty-two without learning something about holding on to it." Tolliver blinked. He had taken her for three or four years older. Betty, and Tolliver thought he muttered something about "just landed." Tolliver, hardly thinking about it, expected the someone to be Tolliver started for the door immediately, but was blocked off. Tolliver brought up a snappy uppercut to the man's chin, feeling that Betty. The others were swarming over Tolliver. Jeffers came around his Tolliver found himself dumped on the floor of an empty office in the He heard an indignant yelp, and realized that the girl had been pitched in with him. The snapping of a lock was followed by the tramp of departing footsteps and then by silence. Tolliver grunted. Sorrow would not reduce the throbbing, nor was he "Thanks for letting me know in time," said Tolliver. "What can we use to get out of here?" he mused. "Why should we try?" asked the girl. "What can he do?" "You'd be surprised. How did you catch on to him so soon?" "Your paycheck," said Betty. "As soon as I saw that ridiculous amount, Tolliver groaned. "Then, on the way over here, he as good as admitted everything. You didn't hear him, I guess. Well, he seemed to be caught all unaware, and seemed to blame you for it." accident!" "What do you think you're up to?" asked Betty with some concern. "I'll come along with you, Tolliver," said the girl. "Why not?" "Well ... after all, what would he dare do? Arranging an accident to the daughter of the boss isn't something that he can pull off without a lot of investigation. He'd be better off just running for it." "Let's not argue about it," said Betty, a trifle pale but looking "That switch under your chin," he said, touching helmets so she could hear him. "Leave it turned off. Anybody might be listening!" then trailed along with the plastic under his arm. He caught up and touched helmets again. "Just act as if you're on business," he told her. "For all anyone can see, we might be inspecting the dome." They had to cross one open lane between buildings, and Tolliver was From the corner of his eye, he thought he saw Betty make a startled They'll find it, all right , Tolliver reminded himself. Don't be here when they do! It promptly developed that she had something to learn about running on ice in such low gravity. Until they were out of direct line of sight from the settlement, Tolliver simply dragged her. Then, when he decided that it was safe enough to pause and tell her how to manage better, the sight of her outraged scowl through the face-plate made him think better of it. There seemed to be no one about. The landing dome had been collapsed and stored, and the ship's airlock port was closed. "That's all right," Tolliver told the girl. "We can get in with no trouble." It was when he looked about to make sure that they were unobserved that clumsy trip in their spacesuits, but he wanted to save time. glanced at the gauges and showed her how to open her helmet. "Leave the suit on," he ordered, getting in the first word while she "Takeoff!" shrilled Betty. "What do you think you're going to do? I doing his best to ignore the protests from his partner in crime. He warned her the trip might be long. "I told you not to come," he said at last. "Now sit back!" "Who knows?" retorted Tolliver. "There wasn't time to check Tolliver sighed. In their weightless state, it was no easy task to pry her out of the spacesuit. He thought of inquiring if she needed any further help, but reminded himself that this was the boss's daughter. When Betty produced a memo giving frequency and call sign, he set about "Space Patrol?" whispered Tolliver incredulously. wondering what was behind it all. When he heard Betty requesting assistance in arresting Jeffers and For one thing, though the officer seemed well acquainted with Betty, he never addressed her by the name of Koslow. For another, he accepted the request as if he had been hanging in orbit merely until learning who to go down after. They really sent her out to nail someone , Tolliver realized. course, she stumbled onto Jeffers by plain dumb luck. But she had an idea of what to look for. How do I get into these things? She might have got me killed! Tolliver, saved my neck by making the ship take off somehow, but he If Miss Koslow thinks you should arrest Jeffers, you can call us later on this channel." "Miss Koslow?" repeated the spacer. "Did she tell you—well, no matter! He signed off promptly. The pilot faced Betty, who looked more offended "This 'Miss Koslow' business," he said suspiciously. "He sounded funny about that." The girl grinned. "Relax, Tolliver," she told him. "Did you really believe Daddy would send his own little girl way out here to Ganymede to look for whoever was gypping him?" "Sure. The name's Betty Hanlon. I work for a private investigating Tolliver finished for her. "I guess it's better this way," he said
