This last thought was a hunch that had just occurred to Tom. It was clear that their foe had learned about the arrival of the energy from s.p.a.ce. "But so far," Tom reasoned, "there"s no cause to suppose they know anything about the quake deflectors."
Stalling for time, Tom switched on the radio again and spoke into the mike. "Swift jet to attack planes. Our home base is picking up every word of your threats. Shoot us down and America will consider it an act of war!... Care to risk it?"
There was a moment"s silence, then a reply. "War, you say? How can there be a question of war? War against whom? You do not even know our national ident.i.ty!"
"Don"t kid yourselves, mister!" Bud put in with a snarl. "We know, all right, and so does United States Intelligence!"
Tom decided to risk a blunt query, without actually giving away any facts, in case his hunch about the Brungarian"s knowledge was wrong.
"There was a phone call to Swift Enterprises last night," he radioed.
"We know it was a fake. We also know your agents are aware of our visitor.... Right?"
After a pause, the enemy spokesman replied, "Perhaps. If so, what then?"
"Just this," Tom radioed back. "If you"re hoping to meet our visitor, you"re out of luck. I"ll give you my word for it. Do you think we"d risk such a valuable character in an unguarded crate like this?"
Tom and Bud looked at each other. Somehow, both boys felt instinctively that Tom"s words had struck home. The enemy had certainly risen to the bait.
Finally came the reply. "You Swifts have a reputation for scrupulous honesty." There was a slight sneer in the speaker"s voice as if he considered this a foolish weakness. "You give me your word of honor that this--er--character is not aboard?"
"I do!" Tom snapped. "And if you don"t trust me, go ahead and risk a war!"
The boys waited breathlessly for the outcome of Tom"s bold gamble. Soon they saw the result. The pursuing planes suddenly peeled off and sped away in the direction from which they had first appeared.
"Whew!" Bud wiped his hand across his face and drew it away moist with perspiration. "How do you like that?"
Tom chuckled with relief. "I like it fine, fly boy. But I was sure worried there for a while!"
Less than an hour later, the big cargo jet touched down at the San Rosario airport. An armed guard was on hand to greet the boys, under command of an officer named Captain Sanchez. He had brought along a work crew of soldiers and also a geology expert, Professor Leone, from the island"s small technical school.
"I have selected a spot on the eastern sh.o.r.e of the island," the professor told Tom. He unrolled a map and explained the site.
"Excellent," Tom agreed.
The Quakelizor parts, communications equipment, and small atomic earth blaster were quickly unloaded and transported to the site by trucks. In three hours the installation was finished.
Tom, who spoke Spanish fairly well, explained to a small group of San Rosario military technicians how the quake deflector worked. He also detailed one of his own men to stay on as trouble shooter for the setup.
"And now," said Captain Sanchez, beaming, "we must relax and celebrate the friendship of our two countries."
Tom and Bud, though eager to get home, hesitated to hurt the friendly officer"s feelings. They sat through a delicious meal, followed by numerous speeches. When his own turn to speak came, Tom used it to warn against possible sabotage attempts by the Brungarians. At last the boys were allowed to take off with their crew.
"Swell guys," Bud said, when the boys were airborne, "but a bit hard to break away from!"
Tom grinned, then became serious. "You know, Bud," he said thoughtfully, "those aerial hijackers gave me an idea."
"Let"s have it, skipper."
"If only I could get Exman perfected so he would report back to me," Tom explained, "I could _let_ him be kidnaped. Think what a wonderful "inside man" he"d make in the enemy setup! He could tip us off to everything the Brungarians were doing!"
"Hey, that"s neat!" Bud exclaimed, wide-eyed. "But how could you be sure those Brungarian rebel scientists wouldn"t change him somehow? I mean they might brainwash him or something."
"It"s a risk," Tom agreed. "But that"s my problem--how to make a perfect spy out of him."
It was midnight when the cargo jet touched down on the Enterprises airfield. The boys slept soundly.
The next morning Tom reported to Mr. Swift and Harlan Ames the outcome of his trip to San Rosario, including the attack en route by unmarked sky raiders. He also privately told his father about his plan to use Exman as an electronic spy. Mr. Swift was enthusiastic.
The two scientists promptly set to work. Mr. Swift built two powerful but miniature radio sets; one for receiving, one for transmitting. Tom, meanwhile, was busy on another device, also highly miniaturized, combining features of both the electronic decoder and Tom"s famous midget computers, known as Little Idiots.
With this equipment, Tom hoped, Exman would be able to monitor all communications at Brungarian rebel headquarters, then radio the information to Enterprises.
Chow brought lunch to the laboratory at noon, and Bud came in later.
Both stayed to watch the outcome of the experiment. Hank Sterling and Arv Hanson joined the group.
By midafternoon the equipment was ready for a tryout. Tom opened Exman"s star head, inserted the gear, and made the delicate wiring connections.
"So far, so good," the young inventor murmured, stepping back. "Now for the real test! Will Exman answer our questions?"
Tom walked over to the electronic decoder brain and began to tap out a message on the keyboard. The others waited in breathless suspense.
CHAPTER XV
KIDNAPED!
The message which Tom signaled in code over the electronic brain said:
WE HAVE A DANGEROUS PLAN. IF PLAN WORKS, YOU MAY BE EXPOSED TO ENEMY TAMPERING. WILL THIS BE SAFE? CAN YOU STAND THIS?
There was a tense pause. Then the signal bell rang on the machine and the keys began to punch out a reply on tape:
NO ONE CAN ALTER THIS BRAIN NOR CAN THEY CHANGE ITS PURPOSE.
THEY CAN ONLY DESTROY THE ENERGY HOLDER.
As Tom finished reading the message aloud, Chow gave a whoop of delight and the whole group burst into spontaneous cheers.
"Terrific, skipper!" Bud exclaimed, clapping his pal on the back. The others gathered around to add their congratulations.
Mr. Swift, beaming with pride, gave Tom a quick hand-squeeze. "It"s an amazing achievement, son. And it may prove to be the key for unlocking the secrets of s.p.a.ce, if and when we have time for some research after this crisis is over."
"I sure hope so, Dad," Tom murmured. Though jubilant, the young inventor realized that this was only the first step in his plan to checkmate the Brungarian rebels.
_The real perils still lay ahead!_
