As soon as the professor had gone his fear vanished. What he had said to Dr. Kramer gave away no secrets and, in any case, he was crediting the professor with a perception he did not have. Ever since first joining the Movement, when he was still in school, Dirrul had taken such pains to conceal his motives that it would have required a good deal more than Dr. Kramer's clumsy prying to reveal them.

He had deliberately patterned his attitudes and habits upon a composite average, even to a mild and starry-eyed criticism of the system which was more or less expected from the ambitious young men of the Air-command.

Dr. Kramer's ecstatic praise of the system was the typical emotional reaction of the older generation. The professor may actually have been convinced of the truth of his own fuzzy propaganda. It was that sort of blind faith which still held the Planetary Union together.

Before returning to the Air-Command base at noon, Dirrul sought out Paul Sorgel and reported that Glenna and Hurd were safely on their way to Vinin. Apologetically, he mentioned Dr. Kramer's invitation, expecting to elicit Sorgel's scorn. Instead the Vininese agent was enthusiastic.

"Wonderful, Eddie!" he said. "Engineer it so they'll ask you back. We've never got one of our people in with the older science crowd before. Feel them out—we might pick up some converts. I won't need you at the next few meetings of the Movement—they'll be largely reorganizational, you know. I've been reading over Glenna's notes on the Plan. With one or two modifications we should be able to carry it out."

At eight-thirty that evening Dirrul was admitted to Dr. Kramer's apartment. He was neither overwhelmed by the professor's excessive courtesy nor impressed by the other guests. They were from the faculty of the Advanced Air University, elderly, respected and distinguished, names known for a generation everywhere in the Planetary Union.

To them, Edward Dirrul was merely a curiosity, a live specimen mounted for analysis. He had criticised their system. They intended to wring out the strands of his motivation, classify them, speculate and theorize upon them—and perhaps, ultimately, do the whole thing up as a monograph.

Dirrul knew why Kramer had selected him for study rather than any of the current crop of university students who held similar views. A product of the educational philosophy of the Planetary Union, Dirrul was thoroughly adjusted and decidedly aware of both his own abilities and shortcomings.

He was, first of all, gifted in the use of abstractions and generalities. In rare combination with this flair he had superior mechanical intelligence and a talent for expressive verbalization. He dealt easily in the subtle skills of logic. If he set his mind to it, he could erect absolute proofs of diametrically opposed truths and few minds could detect the delicately concealed flaws in the reasoning.

On the negative side of the scale was Dirrul's complete lack of psycho-biological intelligence, or a sense of scientific semantics. Neither to him seemed important. He missed them not at all and resented the legal requirements that forced him to take Dr. Kramer's course before he could qualify as a space-pilot.

The papers he had written for the professor were beautifully constructed patterns of logic, cast in well-turned phrases. They had clarified the criticism which others put inarticulately. It was the precision of his argument that disturbed Dr. Kramer and his faculty friends.

Dirrul was amused as the distinguished scientists skillfully manipulated the conversation to create counter-arguments opposing his. It was a game played in abstractions, a technique of which Dirrul was an instinctive master. Apparently the scientists found some sort of excitement in the game, since on succeeding evenings Dirrul was swamped with invitations from other faculty members—so many, in fact, that he had to neglect the serious work of the Movement. When he complained to Paul Sorgel, the Vininese agent was delighted.

"We can get along without you for awhile, Eddie," Sorgel said. "You're doing something much more important. You have a real in with the science crowd, and you've got them on the run because your arguments make sense. Every doubt you sow in their minds now will make our work just that much easier when the proper time comes."

Occasionally Dirrul had an uneasy feeling that he was making no real progress at all, that when he talked to the scientists he was a dancing puppet dangling on invisible strings. It seemed impossible that the scientists of the Ad-Air University could be so repeatedly defeated by his logic. Slowly, however, he reasoned his way to an explanation.

The scientists, like the system itself, were in the last wild frenzy of a decaying social order. They had lived so long in the atmosphere of relative truths, they had so carefully schooled themselves to avoid all absolutes, that they were unable to elude the simplest processes of logic. Their very efforts to be objective made them too honest to reject a conclusion once Dirrul had demonstrated the careful structure that seemed to support it.

A month passed. Dirrul felt divorced from the Movement, existing in suspended animation in a cloud of wordy unreality. Then abruptly the slow-moving dream ended. Late one night Paul Sorgel slipped into Dirrul's apartment and announced in an emotionless whisper, "The Plan's ready. You'll have to carry the details to Vinin. We can't use the teleray—the Union monitors might pick up the message and decode it."

"Naturally our Vininese Headquarters will want to know, Paul," said Eddie, "but can't that wait? We'll need every man here when we—"

Sorgel interrupted him. "I've made one or two changes in Glenna's original plan. It was too impractical. A handful of men can't take over half a galaxy."

"Glenna and Hurd weren't after the entire Planetary Union, Paul—that's out of the question. We meant to liberate Agron first. The capital is here and for awhile the government would be disrupted. When the people on the other planets saw how much better our social organization had become, modeled on the Vininese system, they would stage their own revolutions just like ourselves."

Sorgel laughed scornfully. "And in the meantime, of course, none of them would think of attacking you and throwing your people out?"

"Not if we seized the Nuclear Beam Transmitters," said Dirrul, "no space-fleet could come near us then."

"Eddie, you've lived in Agron too long. You're not thinking straight when you try to build the Plan around a single weapon."

"Why not, Paul? It's a perfect defense. In less than thirty seconds the Beam Transmitters can charge the entire stratospheric envelope of Agron. Nothing can move through it without disintegrating, yet life on the surface of the planet would go on quite normally because the atmosphere serves as an insulation."

"Technically it's a change in the form of energy, not a disintegration," Sorgel reminded him. "The beamed electrons unite with the atoms of visible material substances and alter them. I quite understand the process, Eddie—Vinin has the Beam too, you know."

"Because the Agronian scientists gave you the specifications!"

"That always has rankled, hasn't it?" said Sorgel.

"Yes," Dirrul admitted. "If the Vininese scientists had discovered the Beam-reaction first they would have conquered the galaxy."

"Conquer is a nasty word, Eddie," Sorgel said softly. "Vinin makes no conquests. Let's put it differently and say we would have used the Beam to bring peace to the galaxy instead of splitting it in two as it is now."

"Glenna's Plan can change all that, at least here on Agron."

"Face the facts, Eddie! A few conscientious people with ideals can't take over a planet. The Movement has its crews trained to capture the Beam Transmitters. You'll isolate Agron and seize the government offices simultaneously. What happens then?"

"Our people will rise and join us," said Eddie. "We'll create a new government modeled on Vinin's and we'll have young leaders instead of murky thinkers like Dr. Kramer."

"That's effective propaganda for speechmaking, but—"

"Glenna pounded away at it too, Paul," said Eddie. "It was the most telling line in winning our new crop of recruits."

"Which is precisely why the police disposed of her. But it won't work. The people won't rise. A mob is lethargic, too willing to keep things as they are. Here on Agron you've been coddled too long with luxuries and easy living. You have to prod the mob awake with a shock-force, a force coming from the outside."

"How, Paul? We haven't enough people in the Movement to put on any real show of strength. We can't even get outside."

"Now you understand the changes I've made in Glenna's Plan. You people in the Movement will seize the Beam Transmitters as originally planned. Then you'll simply hold them and keep them decommissioned long enough for a Vininese space-fleet to land. We'll set up your new government for you."

"And the rest of the Planetary Union will go to war!"

"It hardly matters," said Paul. "Once we're here the Beams will protect us against counterattack and every planet in the Vininese Confederacy has the same defense. One by one we can liberate the planets of the Union in the same way. But the timing is vital, of course—that's why you have to go to Vinin."

"I had a vacation leave only three months ago. I can't get tourist passage now without—"

"I've considered that. You'll have to have your own space-ship."

"Now wait a minute, Paul! It's one thing to borrow a surface jet but a space-cruiser...!"

"A cruiser, yes—not an old cargo ship. And you can handle that without a crew."

"It can't be done, Paul." Dirrul held his Glo-Wave nervously to the end of a cigarette. "Besides, I want to think this through carefully before I make up my mind."

"A merchant ship made a crash landing at Barney's emergency field yesterday," said Paul. "The damage was slight, but the pilot—unfortunately the pilot is dead." Sorgel smiled enigmatically. "Barney's one of our best men. He's been on the lookout for a chance like this for weeks.

"You'll leave tonight. Avoid the regular space lanes. I'm guessing you'll be on Vinin in a hundred days at the outside. On the fiftieth day after that—exactly one hundred and fifty days from now—our Vininese space-fleet must make a landing on Agron."

"I'll be missed, Paul—they'll make inquiries."

"And get no satisfactory answers."

Pacing the floor, Dirrul asked tensely, "Does everyone in the Movement know about this?"

"The vote was made unanimously yesterday."

"One of the others must have a vacation leave coming up. Send him. We're not at war with Vinin. He could take one of the regular space excursions."

"I can't send a message in writing. It would be picked up by the customs police. And you're the only one who can carry it verbally, Eddie. You know the whole background because you worked with Glenna and Hurd. You've been in the Movement longer than any of the others."

"Why not go yourself, Paul?"

"I can do more for the liberation if I stay here."

"I wish I'd been at the meeting yesterday when the vote was taken. I'd have liked to discuss it with the others before—"

"Why so many questions, Eddie? Why so many doubts all of a sudden?" Sorgel stood and faced Dirrul, holding his shoulders in a grip that hurt. "Are you trying to back out? Maybe it wasn't a good thing to let you play around with the science boys after all. Be honest with me, Eddie. If you're not sure where you stand, say so. There's no room in the Movement for traitors."

When Dirrul said nothing Sorgel added in a voice that rang with fervor, "You're the only man in the Movement who has had any training as a space-pilot. It depends on you now—everything you've ever dreamed of, everything Glenna and Hurd wanted. Can you forget what the Agronian police did to Glenna? Is your courage any less than hers?" Again Sorgel paused but still Dirrul said nothing. "The future of your world depends on you, Eddie—don't let it down."

"I'll go," Dirrul whispered.

As Eddie made up his mind his internal tension relaxed and he was filled with a sense of well-being. When he thought about it he couldn't understand why he had hesitated—unless perhaps what Sorgel suggested was true—that his contact with the Ad-Air faculty had blunted and nearly perverted his established sense of values.

An hour later Dirrul boarded the battered antiquated space cargo carrier on the launching rack at Barney's emergency field. At the last minute Sorgel pressed a curious disk into his hand. Made of a very light metal and suspended from a short chain it was two inches in diameter and covered with a complex grid design.

"Put it around your neck before you land, Eddie. Don't remove under any circumstances until you report. Give it to the Chief then. He'll know I sent you because it's my own identification activator." Sorgel clasped Dirrul's hand warmly. "When you land on Vinin take the North Field below the capital. It's the HQ operational center. Use Wave-code three-seven-three and they'll know you're friendly."
