  “I thought he talked good sense,” remarked Mays. The High Priest of Computing had a slow, measured style of delivery that contrasted quaintly with the lightning speed of his machines.

  “Whose side are you on?” someone asked suspiciously.

  “Oh, I’m a friendly neutral.”

  “But Earth pays your salary. Which side would you support if there was a showdown?”

  “Well that would depend on the circumstances. I’d like to support Earth. But I reserve the right to make up my own mind. Whoever it was who said ‘My planet right or wrong’ was a damned fool. I’d be for Earth if it was right, and would probably give it the benefit of the doubt in a borderline case. But I’d not support it if I felt its cause was definitely wrong.”

  There was a long silence while everyone thought this over. Sadler had been watching Mays intently while the mathematician was speaking. Everyone, he knew, respected Mays’s honesty and logic. A man who was actively working against Earth would never have expressed himself as forthrightly as this. Sadler wondered if Mays would have spoken any differently had he known that a counter-intelligence man was sitting within two meters of him. He did not believe that he would have altered a word.

  “But, blast it,” said the chief engineer, who as usual was blocking the synthetic fire, “there’s no question of right and wrong here. Anything found on Earth or Moon belongs to us, to do with as we like.”

  “Certainly, but don’t forget we’ve been falling back on our quota deliveries, as Beynon said. The Federation has been relying on them for its programs. If we repudiate our agreements because we haven’t got the stuff ourselves, that’s one thing. But it’s a very different matter if we have got it and are just holding the Federation up for ransom.”

  “Why should we do any such thing?”

  It was Jamieson, unexpectedly enough, who answered this. “Fear,” he said. “Our politicians are frightened of the Federation. They know it already has more brains, and one day it may have more power. Then Earth will be a back number.”

  Before anyone could challenge him on this, Czuikov from the Electronics Lab started a fresh hare.

  “I’ve been thinking,” he said, “about that broadcast we’ve just heard. We know that Beynon’s a pretty honest man, but after all he was broadcasting from Venus, with their permission. There may be more in that talk of his than meets the ear.”

  “What do you mean?”

  “He may be putting across their propaganda. Not consciously, perhaps; they may have primed him to say what they want us to hear. That talk about raids, for instance. Perhaps it’s intended to scare us.”

  “That’s an interesting idea. What do you think, Sadler? You’re the last to come up from Earth.”

  This frontal attack took Sadler rather by surprise, but he dexterously tossed the ball back.

  “I don’t think Earth can be frightened as easily as that. But the passage that interested me was his reference to possible new supplies on the Moon. It looks as if rumors are beginning to float around.”

  This was a calculated indiscretion on Sadler’s part. It was not so very indiscreet, however, for there was no one in the Observatory who did not know (a) that Wheeler and Jamie-son had stumbled on some unusual government project in the Mare Imbrium, and (b) that they had been ordered not to talk about it. Sadler was particularly anxious to see what their reactions would be.

  Jamieson assumed a look of puzzled innocence, but Wheeler did not hesitate to rise to the bait.

  “What do you expect?” he said. “Half the Moon must have seen those ships coming down in the Mare. And there must be hundreds of workmen there. They can’t all have come from Earth—they’ll be going into Central City and talking to their girl friends when they’ve had a few drinks too many.”

  How right you are, thought Sadler, and what a headache that little problem was giving Security…

  “Anyway,” continued Wheeler, “I’ve got an open mind on the subject. They can do what they like out there as long as they don’t interfere with me. You can’t tell a thing from the outside of the place, except that it’s costing the poor taxpayer an awful lot of money.”

  There was a nervous cough from a mild little man from Instrumentation, where only that morning Sadler had spent a boring couple of hours looking at cosmic-ray telescopes, magnetometers, seismographs, molecular-resonance clocks, and batteries of other devices which were surely storing information more rapidly than anyone would ever be able to analyze it.

  “I don’t know about them interfering with you, but they’ve been playing hell with me.”

  “What do you mean?” everyone asked simultaneously.

  “I had a look at the magnetic-field-strength meters half an hour ago. Usually the field here is pretty constant, except when there’s a storm around, and we always know when to expect those. But something odd’s going on at the moment. The field keeps hopping up and down—not very much, a few microgauss —and I’m sure it’s artificial. I’ve checked all the equipment in the Observatory, and everyone swears they’re not mucking around with magnets. I wondered if our secretive friends out in the Mare were responsible, and just on the chance, I had a look at the other instruments. I didn’t find anything until I came to the seismographs. We’ve got a telemetering one down by the south wall of the crater, you know, and it had been knocked all over the place. Some of the kinks looked like blasting; I’m always picking that up from Hyginus and the other mines. But there were also some most peculiar jitters of the trace that were almost synchronized with the magnetic pulses. Allowing for the time-lag through the rock, the distance checked up well. There’s no doubt where it comes from.”

  “An interesting piece of research,” Jamieson remarked, “but what does it add up to?”

  “There are probably a good many interpretations. But I’d say that out there in the Mare Imbrium someone is generating a colossal magnetic field, in pulses lasting about a second at a time.”

  “And the moon-quakes?”

  “Just a by-product. There’s a lot of magnetic rock around here, and I imagine it must get quite a jolt when that field goes on. You probably wouldn’t notice that quake even if you were where it started, but our seismographs are so sensitive they can spot a meteor falling twenty kilometers away.”

  Sadler listened to the resulting technical argument with great interest. With so many keen minds worrying around the facts, it was inevitable that some would guess the truth—and inevitable that others would counter it with their own theories. This was not important; what concerned him was whether anyone showed special knowledge or curiosity.

  But no one did, and Sadler was still left with his discouraging three propositions: Mr. X was too clever for him; Mr. X was not here; Mr. X did not exist at all…

  Chapter XI

  Nova Draconis was waning; no longer did it outshine all the suns of the Galaxy. Yet in the skies of Earth it was still brighter than Venus at her most brilliant, and it might be a thousand years before men saw its like again.

  Though it was very near on the scale of stellar distances, N, Draconis was still so remote that its apparent magnitude did not vary across the whole width of the solar system. It shone with equal brilliance above the firelands of Mercury and the nitrogen glaciers of Pluto. Transient though it was, it had turned men’s minds for a moment from their own affairs and made them think of ultimate realities.

  But not for long. The fierce violet light of the greatest nova in history shone now upon a divided system, upon planets that had ceased to threaten each other and were now preparing for deeds.

  The preparations were far more advanced than the public realized. Neither Earth nor the Federation had been frank with its people. In secret laboratories, men had been turning toward destruction the tools which had given them the freedom of space. Even if the contestants had worked in entire independence, it was inevitable that they would have evolved similar weapons, since they were basing them on the same technologies.

  But each side
had its agents and counter-agents, and each knew, at least approximately, the weapons which the other was developing. There might be some surprises—any one of which could be decisive—but on the whole the antagonists were equally matched.

  In one respect, the Federation had a great advantage. It could hide its activities, its researches and tests, among the scattered moons and asteroids, beyond any hope of discovery. Earth, on the other hand, could not launch a single ship without the information reaching Mars and Venus within a matter of minutes.

  The great uncertainty that plagued each side was the ef-fiency of its Intelligence. If this came to war, it would be a war of amateurs. A secret service requires a long tradition, though perhaps not an honorable one. Spies cannot be trained overnight, and even if they could, the kind of flair that characterizes a really brilliant agent is not easy to come by.

  No one was better aware of this than Sadler. Sometimes he wondered if his unknown colleagues, scattered over the solar system, felt equally frustrated. Only the man at the top could see the complete picture—or something approaching it. He had never realized the isolation in which a spy must work, the horrible feeling that you are alone, that there is no one you can trust, no one with whom you can share your burdens. Since he had reached the Moon, he had—at least to his knowledge —spoken to no other member of Central Intelligence. All his contacts with the organization had been impersonal and indirect. His routine reports—which to any casual reader would have seemed extremely dull analyses of the Observatory’s accounts—went by the daily monorail to Central City, and he had little idea what happened to them after that. A few messages had arrived by the same means, and in the event of teal emergency the teleprinter circuit was available.

  He was looking forward to his first meeting with another agent, which had been arranged weeks in advance. Though he doubted if it would be of much practical value, it would give his morale a badly needed boost.

  Sadler had not, to his own satisfaction at least, acquainted himself with all the main aspects of Administration and Technical Services. He had looked (from a respectful distance) into the burning heart of the micro-pile which was the Observatory’s main power source. He had watched the big mirrors of the solar generators, waiting patiently for the sunrise. They had not been used for years, but it was nice to have them around in case of any emergency, ready to tap the limitless resources of the sun itself.

  The Observatory farm had surprised and fascinated him most of all. It was strange that in this age of scientific marvels, of synthetic this and artificial that, there were still some things in which Nature could not be excelled. The farm was an integral part of the air-conditioning system, and was at its best during the long lunar day. When Sadler saw it, lines of fluorescent lamps were providing substitute sunlight, and metal shutters had been drawn over the great windows which would greet the dawn when the sun rose above the western wall of Plato.

  He might have been back on Earth, in some well-appointed greenhouse. The slowly moving air passed along the rows of growing plants, gave up its carbon dioxide and emerged not only richer in oxygen, but also with that indefinable freshness which the chemists had never been able to duplicate.

  And here Sadler was presented with a small but very ripe apple, every atom of which had come from the Moon. He took it back to his room where he could enjoy it in privacy, and was no longer surprised that the farm was out of bounds to everyone except the men who tended it. The trees would soon be stripped if any casual visitor could wander through these verdant corridors.

  The Signals section was just about as great a contrast as could be imagined. Here were the circuits that linked the Observatory with Earth, with the rest of the Moon, and if necessary with the planets direct. It was the greatest and most obvious danger point. Every message that came or went was monitored, and the men who operated the equipment had been checked and rechecked by Security, Two of the staff had been transferred, without knowing the reason, to less sensitive jobs. Moreover—even Sadler did not know this—a telescopic camera thirty kilometers away was taking a photograph every minute of the big transmitting arrays which the Observatory used for long-distance work. If one of these radio searchlights happened to point for any length of time in an unauthorized direction, the fact would soon be known.

  The astronomers, without exception, were all very willing to discuss their work and explain their equipment. If they won dered at some of Sadler’s questions, they gave no sign of it. For his part, he was very careful not to step outside of his adopted role. The technique he used was the frank man-to man one: “Of course this isn’t really my job, but I’m quite interested in astronomy, and while I’m here on the Moon I went to see all I can. Naturally, if you’re too busy at the mo ment ” It always worked like a charm.

  Wagnall usually made the arrangements and smoothed the way for him. The secretary had been so helpful that at first Sadler wondered if he was trying to safeguard himself, but further inquiry had shown that Wagnall was like that. He was one of those people who cannot help trying to create a good impression, simply because they want to be on good terms with everybody. He must find it singularly frustrating, Sadler thought, working for a cold fish like Professor Maclaurin.

  The heart of the Observatory was, of course, the thousand-centimeter telescope—the largest optical instrument ever made by man. It stood on the summit of a slight knoll some distance from the residential area and was impressive rather than elegant. The enormous barrel was surrounded by a gantry-like structure which controlled its vertical movement, and the whole framework could rotate on a circular track.

  “It’s not a bit like any of the telescopes back on Earth,” explained Molton as they stood together inside the nearest observation dome, looking out across the plain. “The tube, for instance. That’s so we can still work during the day. Without it, we’d get sunlight reflected down into the mirror from the supporting structure. That would ruin our observations, and the heat would distort the mirror. It might take hours to settle down again. The big reflectors on Earth haven’t got to worry about this sort of thing. They’re only used at night—those that are still in action at all.”

  “I wasn’t sure that there were any active observatories left on Earth,” Sadler remarked.

  “Oh, there are a few. Nearly all training establishments, of course. Real astronomical research is impossible down in that pea-soup of an atmosphere. Look at my own work, for instance —ultra-violet spectroscopy. The Earth’s atmosphere is completely opaque to the wavelengths I’m interested in. No one ever observed them until we got out into space. Sometimes I wonder how astronomy ever started down on Earth.”

  “The mounting looks odd to me,” Sadler remarked thoughtfully, “It’s more like that of a gun than any telescope I’ve ever seen.”

  “Quite correct. They didn’t bother about an equatorial mounting. There’s an automatic computer that keeps it tracking any star we set it on. But come downstairs and see what happens at the business end.”

  Molton’s laboratory was a fantastic maze of half-assembled equipment, scarcely any of which Sadler could recognize. When he complained about this, his guide seemed highly amused.

  “You needn’t feel ashamed of that We’ve designed and built most of it here; we’re always trying out improvements. But roughly speaking, what happens is this. The light from the big mirror—we’re directly underneath it here—is piped down through that tube over there. I can’t demonstrate at the moment, as someone is taking photographs and it’s not my turn for another hour. But when it is, I can select any part of the sky I like from this remote-control desk here and lock the instrument on to it. Then all I have to do is to analyze the light with these spectroscopes. You can’t see much of their works, I’m afraid—they’re all totally enclosed. When they’re in use the whole optical system has to be evaluated, because as I mentioned just now even a trace of air blocks the far ultraviolet rays.”

  Sadler was suddenly struck by an incongruous thought.

&nbs
p; “Tell me,” he said, glancing round the maze of wiring, the batteries of electronic counters, the atlases of spectral lines, “have you ever looked through this telescope?”

  Molton smiled back at him.

  “Never,” he said. “It wouldn’t be hard to arrange, but there would be absolutely no point in it. All these really big telescopes are super-cameras. And who wants to look through a camera?”

  There were, however, telescopes at the Observatory through which one could look without too much trouble. Some of the smaller instruments were fitted with TV cameras which could be swung into position when it was necessary to search for comets or asteroids whose exact locations were unknown. Once or twice Sadler managed to borrow one of these instruments, and to sweep the skies at random to see what he could find. He would dial a position on the remote-control board, then peer into the screen to see what he had caught. After a while he discovered how to use the Aeronautical Almanac, and it was a great moment when he set up the co-ordinates for Mars and found it bang in the middle of the field.

  He stared with mixed feelings at the green-and-ocher disk almost filling the screen. One of the polar caps was tilted slightly sunward—it was the beginning of spring, and the great frost-covered tundras would be slowly thawing after the iron winter. A beautiful planet to watch from space, but a hard planet on which to build a civilization. No wonder its sturdy children were losing patience with Earth.

  The image of the planet was incredibly sharp and clear. There was not the slightest tremor or unsteadiness as it floated in the field of view, and Sadler, who had once glimpsed Mars through a telescope on Earth, could now see with his own eyes how astronomy had been liberated from its chains when the atmosphere had been left behind. Earth-bound observers had studied Mars for decades through instruments larger than this, but he could see more in a few hours than they could have glimpsed in a lifetime. He was no nearer to Mars than they had been—indeed, the planet was now at a considerable distance from Earth—but there was no dancing, quivering haze of air to veil his view.
