The Jupiter Four command ship had taken eleven months to reach the giant planet. Within four hours of the event, the latest information to be gathered by the mission was safely lodged in the data banks of UN Space Arm.

The discovery of the giant spaceship, frozen under the ice field of Ganymede, was a sensation but, in a sense, not something totally unexpected. The scientific world had more or less accepted as fact that an advanced civilization had once flourished on Minerva; indeed, if the arguments of the orthodox evolutionists were accepted, at least two planets-Minerva and Earth-had supported high-technology civilizations to some extent at about the same time. It did not come as a complete surprise, therefore, that man’s persistent nosing around the Solar System should uncover more evidence of its earlier inhabitants. What did surprise everybody was the obvious anatomical difference between the Ganymeans-as the beings on board the ship soon came to be called-and the common form shared by the Lunarians and mankind.

To the still unresolved question of whether the Lunarians and the Minervans had been one and the same or not, there was immediately added the further riddle: Where had the Ganymeans come from, and had they any connection with either? One bemused UNSA scientist summed up the situation by declaring that it was about time UNSA established an Alien Civilizations Division to sort out the whole damn mess!

The pro-Danchekker faction quickly interpreted the new development as full vindication of evolutionary theory and of the arguments they had been promoting all along. Clearly, two planets in the Solar System had evolved intelligent life at around the same period in the past; the Ganymeans had evolved on Minerva and the Lunarians had evolved on Earth. They came independently from different lines and that was why they were different. Lunarian pioneers made contact with the Ganymeans and settled on Minerva-that was how Charlie had come to be born there. Extreme hostilities broke out between the two civilizations at some point, resulting in the extinction of both and the destruction of Minerva. The reasoning was consistent, plausible, and convincing. Against it, the single objection-that no evidence of any Lunarian civilization on Earth had ever been detected-began to look more lonely and more feeble every day. Deserters left the can’t-be-of-Earth-origin camp in droves to join Danchekker’s growing legions. Such was his gain in prestige and credibility that it seemed perfectly natural for his department to assume responsibility for conducting the preliminary evaluation of the data coming in from Jupiter.

Despite his earlier skepticism, Hunt too found the case compelling. He and a large part of Group L’s staff spent much time searching every available archive and record from such fields as archeology and paleontology for any reference that could be a pointer to the one-time existence of an advanced race on Earth. They even delved into the realms of ancient mythology and combed various pseudoscientific writings to see if anything could be extracted that was capable of substantiation, that suggested the works of superbeings in the past. But always the results were negative.

While all this was going on, things began to happen in an area where progress had all but ground to a halt for many months. Linguistics had run into trouble: The meager contents of the documents found about Charlie’s person simply had not contained enough information to make great inroads into deciphering a whole new, alien language. Of the two small books, one-that containing the maps and tables and resembling a handy pocket reference-together with the loose documents, had been translated in parts and had yielded most of the fundamental data about Minerva and quite a lot about Charlie. The second book contained a series of dated entries in handwritten script, but despite repeated attempts, it had obstinately defied decoding.

This situation changed dramatically some weeks after the opening up of the underground remains of the devastated Lunarian base on Lunar Farside. Among the pieces of equipment included in that find had been a metal drum, containing a series of glass plates, rather like the magazines of some slide projectors. Closer examination of the plates revealed them to be simple projection slides, each holding a closely packed matrix of nilcrodot images which, under a microscope, were seen to be pages of printed text. Constructing a system of lamps and lenses to project them onto a screen was straightforward, and in one fell swoop Linguistics became the owners of a miniature Lunarian library. Results followed in months.

Don Maddson, head of the Linguistics section, rummaged through the litter of papers and files that swamped the large table standing along the left-hand wall of his office, selected a loosely clipped wad of typed notes, and returned to the chair behind his desk.

"There’s a set of these on its way up to you," he said to Hunt, who was sitting in the chair opposite. "I’ll leave you to read the details for yourself later. For now, I’ll just sum up the general picture."

"Fine," Hunt said. "Fire away."

"Well, for a start, we know a bit more about Charlie. One of the documents found in a pouch on the backpack appears to be something like army pay records. It gives an abbreviated history of some of the things he did and a list of the places he was posted to-that kind of thing."

"Army? Was he in the army, then?"

Maddson shook his head. "Not exactly. From what we can gather, they didn’t differentiate much between civilian and military personnel in terms of how their society was structured. It’s more like everybody belonged to different branches of the same big organization."

"A sort of last word in totalitarianism?"

"Yeah, that’s about it. The State ran just about everything; it dominated every walk of life and imposed a rigid discipline everywhere. You went where you were sent and did what you were told to do; in most cases, that meant into industry, agriculture, or the military forces. Whatever you did, the State was your boss anyway… that’s what I meant when I said they were all different branches of the same big organization."

"Okay. Now, about the pay records?"

"Charlie was born on Minerva, we know that. So were his parents. His father was some kind of machine operator; his mother worked in industry, too, but we can’t make out the exact occupation. The records also tell us where he went to school, for how long, where he took his military training-everybody seemed to go through some kind of military training-and where he learned about electronics. It tells us all the dates, too."

"So he was something like an electronics engineer, was he?" Hunt asked.

"Sort of. More of a maintenance engineer than a design or development engineer. He seems to have specialized in military equipment-there’s a long list of postings to combat units. The last one is interesting-" Maddson selected a sheet and passed it across to Hunt. "That’s a translation of the last page of postings. The final entry gives the name of a place and, alongside it, a description which, when translated literally, means ‘off-planet.’ That’s probably the Lunarian name for whatever part of our Moon he was sent to."

"Interesting," Hunt agreed. "You’ve found out quite a lot more about him."

"Yep, we’ve got him pretty well taped. If you convert their dates into our units, he was about thirty-two years old at the date of his last posting. Anyhow, that’s all really incidental; you can read the details. I was going to run over the picture we’re getting of the kind of world he was born into." Maddson paused to consult his notes again. Then he resumed: "Minerva was a dying world. At the time we’re talking about, the last cold period of the Ice Age was approaching its peak. I’m told that ice ages are Solar System-wide phenomena; Minerva was a lot farther from the Sun than here, so as you can imagine, things were pretty bleak there."
