nothing but trained monkeys. If they have any results, it’s because they are taking them from the Puzzle Network. What has your group found so far?”
That was a tricky question. Milly was working for Jack Beston and the Argus Station, but she felt honor-bound to abide by the rules posted at the Puzzle Network: Nothing that we receive from Odin Station should be sent anywhere else. It may be shared internally, but must be treated as privileged information.
She could not be sure what information, other than the raw signal, the Puzzle Network had received from Philip Beston. Perhaps the fundamentals of signal partitions and the mathematical basics had originated at Odin Station. Milly didn’t share Jack’s wishful thinking that his brother had assembled a team of incompetents.
The one safe area was her own results. Bat had assured her that they were new, which meant they could not have originated in the Bastard’s analysis center.
She provided a quick review of what she had found. Jack’s frequent interruptions for clarification gave her a new appreciation for Megachirops. Her explanations to him had been a hurried and muddled first attempt, yet he had grasped methods and results without asking a single question. As she spoke she heard a loud bang on the door, which she ignored.
When she finished, Jack shook his head. “Interesting, but nothing at all like what we have. Not in the same part of the signal, not in the same area of knowledge. Remember we once talked of using the biological approach, coding the nucleotide bases of DNA?”
“We did. I was skeptical, because it would require that alien evolution follow the same biochemical pattern as ours. But I’ve seen the same suggestion of biological coding made here by a Puzzle Network Master.”
Milly felt a twinge of conscience as she said that — the final comment strayed beyond her own work — but she was reassured when Jack replied, “We’ve gone farther than a suggestion. Pat Tankard and Simon Bitters took some old work of Arnold Rudolph on quaternary codes. They applied it to a forty-million-bit chunk of signal between two sections that we feel sure are image format. The idea was to see if binary digit pairs might match nucleotide bases. Of course, there’s no way of knowing in advance which of the four nucleotide bases corresponds to any particular pair of binary numbers. So Tankard and Bitters took every possible combination of two zeroes and ones. For each case they scanned the whole signal section, looking to see if any recognizable sequence came up again and again. And it did. For one base-to-binary-pair assignment, a ten-letter sequence, GGGCAGGACG, cropped up again and again. It’s used in basic gene-swapping, and it’s present with slight variations in everything from bacteria to humans. This region of the SETI signal is riddled with it. Do you see what this means, Milly?”
She did, very clearly. “The aliens who sent the message are close to us in chemistry and structure. If we have the GACT code, we can look for and read out whole-organism genetic profiles.”
“You bet. And then we may be able to make them! We have the information to build alien life forms, not just learn about them. Now you see why I’m not on my way to Ganymede. We’re on a round-the-clock schedule here, and I’ve got to stay and keep everybody hustling.”
“Do you want me to come back?” Milly was excited, but a little hesitant. She did not share Jack’s total confidence in what the Argus Station crew had done. Every puzzle had an infinite number of wrong answers in addition to the single correct one.
“No. You’re making headway and there are plenty of problems to go round. I told you, all our work has been in one small part of the data, a small fraction of one percent of the whole signal that we’ve started to call the biology site. There must be others — math sites, physics sites, chemistry sites like the one you found, maybe even language sites.
“You stay there, Milly, we go all out — and we leave the Bastard standing!”
Jack vanished from the display, as much of a driven whirlwind as ever. Milly cut the connection before Zetter could reappear for another turf war. She sat down in the cubicle’s sole chair and stared at nothing.
No matter how you looked at it, the Argus Station team had accomplished something of great potential significance. Now the question arose, what was Milly going to do with the information? In principle, the only restriction on her was that she should not give Odin Station data to anyone, especially to Argus Station. What about the other way round? If she followed her natural instincts for open transfer of information, she would tell the Puzzle Network about the Argus Station results. That, in turn, would surely lead to Philip Beston finding out what his brother had accomplished.
But was that a bad thing? The potential gains for everyone were so great, everything from faster-than-light travel to vacuum energy to extended lifespan, it seemed criminal to lock away important results in secret boxes.
Milly made a decision. Her loyalty had to be to the human species, not to any single member or group. She headed along the corridor to Bat’s cubicle. He had said one hour, but in her current mental state time meant nothing. It might have been a full hour, or it could have been only ten minutes.
In any case, if he didn’t want her he could ask her to leave. She had lived through that once tonight already.
A worse situation would be if the expected visitor happened to still be there. Milly was willing to tell Bat about the Argus Station developments, but she could not make such an announcement to a stranger.
She came to Bat’s cubicle, stepped close, and placed her ear against the crack of the door.
Not a sound. Good.
This time at least she would knock.
Milly rapped on the hard plastic, swung the door open, and marched in.
Alex was late. He had been delayed, then delayed, then delayed again. The worst thing was, he couldn’t complain. He knew what was going on and he could even sympathize with it. He had been the cause of similar delays himself, many times. There was always the urge to perform one last test, check one more item of data, add another explanatory comment…
He hoped he didn’t look like Bengt Suomi when he was doing it. The chief scientist of Ligon Industries was dark-haired and dark-complexioned, an extremely tall man with a permanent stoop. He was supremely competent and supremely thorough, but his saturnine countenance suggested that he had never laughed in his whole life. Every result that he had approved for release to Bat appeared to cause him intestinal agony. Twice he had seemed ready to hand over the file, twice he had pulled it back and gone off to verify some small point with one of his staff.
The third time that he had appeared, Alex grabbed the file from Suomi’s hands, whipped up the associated data cube, and ran. He ignored the anxious cry “… but the units of the magnetic field…” that followed him out of the room.
Now he felt like the White Rabbit, scurrying along the endless warren of corridors and tunnels leading to the Puzzle Network’s Command Center. He was late, he was late, and it totally fit his ideas of Puzzle Network members that they had chosen a site on Ganymede that could be found only by negotiating a labyrinth. It had been easier to reach the Bat Cave on Pandora. One thing was certain, there must be an alternate route to this destination. The tunnels were in places so narrow that Bat would have to be greased and fired from a cannon to pass through them.
He was at least half an hour late. He had tried to call ahead on his wrist unit, and typical of Bat there had been no answer. Alex arrived at what should be the final door, hurried through, and found himself in a narrow deserted corridor. The floor was covered by a thick sound-deadening carpet. This was the place, it had to be because it fit Bat’s description — but where was Bat? Alex saw a dozen blue doors, every one closed.
That was all right. No one in his right mind would be here at this hour. That left Bat. Alex went along, banging on each door as he came to it until he heard a deep-voiced, “Yo? Enter.”
Alex’s first impression was of an unlit empty room. Bat, swaddled in black clothing and with a black hood around his head, formed a mound of darkness on a padded seat like the one he had occupied in the Bat Cave.
Alex decided to beat Bat to it. “I’m very late. I’m sorry, but there were last minute changes.”
“The time was not wasted.” Bat held out a hand. “The results, if you please. I assume that you have them?”
“I do, but I’m afraid that you will be disappointed. Bengt Suomi’s team performed two hundred and eighty- seven distinct tests on the nodules taken from Sebastian Birch’s body.” Alex gave Bat the data cube and the sheaf of papers. “I gather you’ve been over many of the early results already with Bengt Suomi. He found only one thing in
