John shut off the TV and took the elevator down to the dorm. He got into bed and relaxed. Karate as ballet. The newcomers were all still engineers, construction workers, scientists of all kinds; but they didn’t seem as single-minded as the first hundred, and that was probably good. They still had a scientific mindset and worldview, they were practical, empirical, rational; one could hope that the selection process on Earth was still working against fanaticism, sending up people with a kind of traveling-Swiss sensibility, practical but open to new possibilities, able to form new loyalties and beliefs. Or so he hoped. He knew by now it was a bit naive. You only had to look at the first hundred to realize scientists could become as fanatical as anybody else, maybe more so; educations too narrowly focused, perhaps. Hiroko’s team disappearing… Out there in the wild rock somewhere, lucky bastards… He fell asleep.

He worked at Echus Overlook a few days more, then got a call from Helmut Bronski in Burroughs, who wanted to confer with him about the new arrivals from Earth. John decided to take the train to Burroughs and see Helmut in person.

The night before his departure, he went to see Sax in his labs; when he walked in Sax said in his monotone, “We’ve found an Amor asteroid that’s ninety percent ice, in an orbit that will bring it near Mars in three years. Just what I’ve been looking for, in fact.” His plan was to place a robot-controlled mass driver on an ice asteroid and push it into an aerobraking orbit around Mars, thus burning it up in the atmosphere. This would satisfy UNOMA protocols forbidding the kind of mass destruction that a direct impact would cause, but it would still add massive quantities of water and separated hydrogen and oxygen to the atmosphere, thickening it with precisely the gases they needed most. “It could raise the atmospheric pressure by as much as fifty millibars.”

“You’re kidding!” The pre-arrival average at the datum had been between seven and ten millibars (Earth’s sea level averaged 1013), and all their efforts so far had only raised the average to around fifty. “One iceball will double the atmospheric pressure?”

“That’s what the simulations indicate. Of course with the initial level so low, doubling is not as impressive as it sounds.”

“Still, that’s great, Sax. And it’ll be hard to sabotage.”

But Sax didn’t want to be reminded of that. He frowned slightly, and slipped away.

John laughed at his skittishness, and went to the door. Then he stopped to think, and looked up and down the hall. Empty. And no video monitors in Sax’s offices. He went back in, grinning at his own furtive tiptoes, and glanced around at the paper chaos on Sax’s desk. Where to start? Presumably his AI would be the repository of anything interesting, but probably it would only respond to Sax’s voice, and would surely keep a record of any other inquiries. Quietly he opened a desk drawer. Empty. All the drawers in the desk were empty; he almost laughed out loud, stifled it. There was a stack of correspondence on a lab bench; he picked through it. Mostly notes from the biologists at Acheron. At the bottom of the stack was a single sheet of unsigned mail, with no return address or origin code; Sax’s printer had spit it out without any identification that John could see. The message was brief:

“1). We use suicide genes to curb proliferation. 2). There are so many heat sources now on the surface that we don’t think anyone can tell our exhaust from the rest of it. 3). We simply agreed we wanted to get off and work on our own, without interference. I’m sure you understand now.”

After a minute of staring at this John whipped his head up and looked around. Still alone. He glanced at the note again, put it back where he had found it and walked quietly out of Sax’s offices, back to the guest quarters. “Sax,” he said admiringly, “you tricky congress of rats!”

The train to Burroughs carried mostly freight, thirty narrow cars of it, with two passengers cars up front, running over a superconducting magnetic piste so quickly and smoothly that it was hard to believe the view; after John’s endless plods cross-country in rovers, it was almost frightening. The only thing to do was flood the pleasure centers in the old brain with omegandorph and sit back and enjoy it, looking out at what appeared to be some kind of terrain-following supersonic flight.

The piste had been routed roughly parallel to the 10° N latitude; eventually the plan was to ring the planet, but so far only the hemisphere between Echus and Burroughs had been finished. Burroughs had become the biggest town in the far hemisphere; the original settlement had been built by an American-based consortium, using a French-led EEC design; it was located at the upper end of Isidis Planitia, which was in effect a huge trough where the northern plains made a deep indentation into the southern highlands. The sides and head of the trough counteracted the planet’s curvature in such a way that the landscape around the town had something like terran horizons, and as the train flew down the great trough Boone could see across mesa-dotted dark plains to horizons some sixty kilometers away.

Burroughs’s buildings were almost all cliff-dwellings, cut into the sides of five low mesas that were grouped together on a rise in the bend of an ancient curving channel. Big sections of the mesas’ vertical sides had been filled by rectangles of mirrored glass, as if postmodern skyscrapers had been turned on their sides and shoved into the hills. A startling sight, in fact, and far more impressive than Underhill, or even Echus Overlook, which had a great view but could not be seen. No, the glass-sided mesas of Burroughs, on their rise over a channel that seemed to be begging for water, with a view out to distant hills; these features combined to give the new town a quickly growing reputation as the most beautiful city on Mars.

Its western train station was inside one of the excavated mesas, a glass-walled room sixty meters high. John stepped out into this grand space and made his way through the crowds of people, head craned back like a hick in Manhattan. Train crews were dressed in blue jumpers, prospecting teams in walker green, UNOMA bureaucrats in suits, construction workers in work jumpers, colored like rainbows to suggest sportswear. UNOMA headquarters had been located in Burroughs three years before, and that had caused a real building boom; it was a close thing whether there were more UNOMA bureaucrats or construction workers in the station.

At the far end of the great room John found a subway entrance, and took a little subway car to the UNOMA headquarters. In the car he shook hands with a few people who recognized and approached him, feeling the old weirdness of the fishbowl return. He was back among strangers. In a city.

That night he had dinner with Helmut Bronski. They had met many times before, and John was impressed by the man, a German millionaire who had gotten into politics: tall, beefy, blond and red-faced, impeccably groomed, dressed in an expensive gray suit. He had been the EEC’s minister of finance when he took the UNOMA post. Now he told John the latest news, in a very urbane British English, eating roast beef and potatoes rapidly between bursts of sentences, holding his silverware in the workmanlike German fashion. “We are going to award a prospecting contract in Elysium to the transnational consortium Armscor. They will be shipping up their own equipment.”

“But Helmut,” John said, “won’t that violate the Mars treaty?”

Helmut made a wide gesture with the hand holding the fork; they were men of the world, his look said, they understood these kinds of things. “The treaty is superannuated, this is obvious to everyone dealing with the situation. But its scheduled revision is ten years away. In the meantime, we have to try to anticipate certain aspects of the revision. That’s why we give some concessions now. There is no rational reason to delay, and if we tried there would be trouble in the general assembly.”
