Tom Swift and the Visitor From Planet X

Close

<h4>DISASTER STRIKES</h4> Tom was thunderstruck. "You didn't phone me? But, Dad, I got the call—I definitely heard your voice!" "That's impossible," Mr. Swift insisted. "Believe me, son, I slept soundly from the time I turned in until a little while ago." There was a moment of stunned silence as both Swifts realized that the telephone call had been faked! Then Tom exclaimed: "Dad, this is serious!" "Deadly serious, I agree," his father replied. "Are you calling from your lab?" "Yes!" "Stay there. I'll be right over," the elder scientist said. When Mr. Swift arrived, Tom related his conversation with the mysterious caller. His father listened with worried eyes and a puzzled frown. 107 "It's bad enough that an enemy was able to get the information," Mr. Swift remarked. "But, potentially at least, it's even more dangerous that he was able to imitate my voice so well. If he could fool you, Tom, he could fool anyone!" "Are you thinking the same thing I am, Dad?" "That it may have been some insider here at Enterprises?" When Tom nodded, his father gravely agreed. "Yes, son, it does look that way. To imitate my voice convincingly, it would almost certainly have to be someone who's had close contact with us—either at the plant or here in Shopton." The thought of a traitor at the experimental station was repugnant to the Swifts and to Bud as well. Not only were all employees carefully screened, but there was a close, almost family relationship among those who took part in the exciting scientific ventures at Swift Enterprises. Tom called Security and asked Harlan Ames to come over to the laboratory at once. The security chief arrived within moments. Quickly Tom filled him in on the details of the puzzling telephone call. "Think back, skipper," Ames urged. "Was there anything at all you can remember about the voice that might give us a tip-off? I mean, was it deep, or maybe a bit higher-pitched than you expected? Or anything about the way the caller pronounced his words?" 108 Tom shook his head. "Nothing. That's the trouble. He spoke only a couple of sentences, but so far as I knew, it was my father calling!" "Hmmm." Ames frowned. "What about background noises?" Tom thought hard. "None. If I had detected any special sounds during the call, I'm sure they would have stuck in my mind." Ames tried another tack. He asked how many people had known about the expected arrival of the brain energy from space. This was harder to answer, but as Tom and his father enumerated the persons, it did help to narrow the circle of suspects. Besides the Swifts, Chow, Phyl, Ames, and George Dilling, there were three groups who had had access to the information. One was the radio operators at the space-communications laboratory. Another consisted of Arv Hanson and Hank Sterling and the workmen who had taken part in building the energy container. The last group, which also included Hank and Arv, were the technicians who had actually gone to the hillside to await the visitor from Planet X. Tom scowled. "None of those people would pull such a trick, Harlan—any more than the ones like you and Arv and Hank who are above suspicion. Most of them could have easily obtained the news without going through such a rigmarole." Mr. Swift nodded. "Tom's right. Unless, of 109 course, they had some urgent reason for wanting to find out as soon as possible." "Which makes me think it may have been an outsider after all," Tom argued. "Remember, the Brungarians may have intercepted the code messages to or from our space friends." After a moment's silence, he added gloomily, "Whoever the caller was, he knew the energy was arriving. And now he knows it's here!" Bud interjected, "Well, if he was a Brungarian agent and he's hoping to steal the brain energy, one thing's sure. No earthquake will demolish this place as long as the energy is here at Enterprises." "A comforting thought, Bud," Mr. Swift commented with a wry smile. Again Tom frowned. "At any rate, Harlan, see if you can get a line on that impostor." Ames departed to begin a thorough check of all personnel at the plant who might have been implicated. Bud went on an errand, as Tom began showing his father the accomplishments of the space robot. "We've christened him Exman," Tom said. By means of the electronic brain, he made the visitor do a number of maneuvers in response to orders. "Wonderful!" Mr. Swift exclaimed, greatly impressed. "Let's see if he can use his caterpillar treads as well as he does the wheels." 110 Tom brought a small flight of portable aluminum stairs which he used for reaching up on high shelves or tinkering with outsized machines. Tom was uncertain at first how to code the command, having no symbol for steps or stairs. Finally he moved Exman to the bottom of the steps and signaled simply: Go up! Exman paused for a moment, then attempted the ascent. His caterpillar tracks clawed their way up the first step. Then, gingerly, he essayed the next. The robot body tilted, but its gyro kept it from toppling over. "Bravo!" Mr. Swift applauded encouragingly. But the next instant Exman gave up! He slid back to the floor again with a heavy bump. Then he began whirling and darting about madly. "Good night! Exman's gone berserk!" Tom cried. Now wafts of smoke could be seen issuing from the robot's wheels. He was banging wildly about the laboratory, leaving a trail of havoc. Bud, who had returned, opened the door to come in. Instantly Exman lunged toward him, antennas sparking fiercely and wheels smoking. Bud slammed the door hastily. The Swifts, too, found it wiser to take cover. They crouched behind a lab workbench until the frenzy was over. Presently Exman subsided and rolled to a complete standstill. "Good grief!" Tom stood up cautiously and 111 eyed the creature. It made no further move. Bud poked his head through the doorway for a wary look, then re-entered the laboratory. "What made him blow his top?" Bud asked. Then Tom heard a quiet chuckle from his father. "Actually, boys," the elder scientist said, "I think we should be encouraged." <ANTIMG src = "images/pic111.jpg" width = "347" height = "289" alt = "(Tom Jr. and Tom Sr. watch as Exman tries to climb stairs)"> "Encouraged?" Tom stared at his father. Mr. Swift nodded. "Yes, the whole thing was rather a noteworthy reaction. I believe Exman was displaying a fear complex about navigating up those stairs." Tom gasped, then broke out laughing. "Dad, you're right! I'll bet when its body tilted over, the 112 brain wasn't sure whether the gyro would keep it from being wrecked. It just shows Ole Think Box is getting more human all the time!" Bud ventured to pat Exman on its "back." "Relax, kid," he said with a chuckle. "You're among friends and we wouldn't dream of letting you get hurt. You're too valuable!" Mr. Swift stroked his jaw thoughtfully. "Valuable, yes, if we can only get it to communicate. Tom, I believe the first project we should work on is a way to make Exman talk." After the debris had been cleaned up, the two scientists pulled up stools to the workbench and began to discuss the problem. Bud, seeing them absorbed, and realizing the discussion would soon be far beyond his depth, snapped a grinning salute at Exman and quietly left the laboratory. "Dad, the toughest part won't be the speech mechanism itself," Tom pointed out. "There are several ways we could handle that—by modulating a column of air, for instance, or by some sort of speaker diaphragm. The real stumper will be how to teach him our spoken language." Mr. Swift nodded. "I'm afraid you're right. If the inhabitants of Planet X communicate telepathically, or by some sort of wave transfer, they may have long since forgotten any concept of a spoken language." The Swifts batted several ideas back and forth. Then Tom snapped his fingers. 113 "Wait, Dad! We have the answer! The electronic brain!" Mr. Swift's eyes lighted up. "Of course! The machine already translates the space code into written English. All we need do is add a device to convert the machine's impulses into sound!" In two hours the Swifts had put together a mechanism designed to work through a tape recorder. This was hooked up to the electronic brain. After recording for several moments, Tom reversed the tape and switched on the playback. A squeaky jumble of noises could be heard. But one word seemed to come through fairly distinctly. "Universe!" "It's talking!" Tom cried out. "Trying to, but not succeeding very well," Mr. Swift said. Nevertheless, the two scientists were jubilant at this first breakthrough. Eagerly they began making adjustments—both on the electronic-brain hookup and the converter mechanism. Tom was just about to switch on the tape recorder again when the telephone rang. The young inventor was annoyed at being interrupted at such a crucial moment, but picked up the phone. "Tom Swift Jr. speaking." "You have an urgent call from Washington," the operator informed him. "Just a moment, please." 114 Bernt Ahlgren was calling from the Pentagon. The defense expert's voice was strained. "Tom, there's just been another attempt to cause an earthquake here in Washington!" Tom gasped. "What happened?" "It failed, thanks to you. But Intelligence believes an attempt will be made on New York City very soon. We need your help to stop it. How near completion are the other shock deflectors?" Before Tom could answer, he heard excited voices at the other end of the line. Then Ahlgren broke in again abruptly. "A news flash, Tom! The Walling range-finder plant has been demolished by an earthquake!" 115 <h5 class = "left chapter">CHAPTER XIV</h5> <div style="break-after:column;"></div>
