“You have to,” Chang said. “It’s the law.”

“What law? What are you going to do to me?” He turned toward the open door of the room, and Chang moved to block him; he lost his temper again and jerked toward Chang, who flinched but remained in the doorway, immovable. John turned and walked away, back down to the commons.

He left Senzeni Na that afternoon in a rover, and took the transponder road north along the eastern flank of Tharsis. It was a good road and three days later he was 1300 kilometers to the north, just northwest of Noctis Labyrinthus, and when he came to a big transponder intersection, with a new fuel station, he hung a right and took the road east to Underhill. Each day as the rover rolled along blindly through the dust, he worked with Pauline. “Pauline, would you please look up all planetary records for theft of dental equipment?” She was as slow as a human in processing an incongruous request, but eventually the data were there. Then he had her go over the movement records of every suspect he could think of. When he was sure where everyone had been, he gave Helmut Bronski a call to protest the actions of Houston and Chang. “They say they’re working with your authorization, Helmut, so I thought you should know what they’re doing.”

“They are trying their best,” Helmut said. “I wish you would stop harrassing them and cooperate, John. It could be helpful. I know you have nothing to hide, so why not be more helpful?”

“Come on, Helmut, they don’t ask for help. It’s rank intimidation. Tell them to stop it.”

“They are only trying to do their job,” Helmut said blandly. “I have not heard of anything illegitimate.”

John broke the connection. Later on he called Frank, who was in Burroughs. “What’s with Helmut? Why is he turning the planet over to these policemen?”

“You idiot,” Frank said. He was typing madly at a computer screen as he talked, so that he seemed to be only barely conscious of what he was saying. “Aren’t you paying any attention at all to what’s going on here?”

“I thought I was,” John said.

“We’re knee deep in gasoline! And these god-damned aging treatments are the match. But you never understood why we were sent here in the first place, so why should you understand anything now?” He typed on, staring hard into his screen.

John studied the little image of Frank on his wrist. Finally he said, “Why were we sent here in the first place, Frank?”

“Because Russia and our United States of America were desperate, that’s why. Decrepit outmoded industrial dinosaurs, that’s what we were, about to get eaten up by Japan and Europe and all the little tigers popping up in Asia. And we had all this space experience going to waste, and a couple of huge and unnecessary aerospace industries, and so we pooled them and came here on the chance that we’d find something worthwhile, and it paid off! We struck gold, so to speak. Which is only more gasoline poured onto things, because gold rushes show who’s powerful and who’s not. And now even though we got a head start up here, there are a lot of new tigers down there who are better at things than we are, and they all want a piece of the action. There’s a lot of countries down there with no room and no resources, ten billion people standing in their own shit.”

“I thought you told me Earth would always be falling apart.”

“This isn’t falling apart. Think about it-if this damned treatment only goes to the rich, then the poor will revolt and it’ll all explode-but if the treatment goes to everyone, then populations will soar and it’ll all explode. Either way it’s gone! It’s going now! And naturally the transnats don’t like that, it’s horrible for business when the world blows up. So they’re scared, and they’re deciding to try to hold things together by main force. Helmut and those policemen are only the smallest tip of the iceberg-a lot of policymakers think a world police state for a few decades or so is our only chance of getting to some kind of population stabilization without a catastrophe. Control from above, the stupid bastards.”

Frank shook his head disgustedly, then leaned toward his screen and became absorbed in its contents.

John said, “Did you get the treatment, Frank?”

“Of course I did. Leave me alone, John, I’ve got work to do.”

The southern summer was warmer than the previous one that had been shrouded in the Great Storm, but still colder than any recorded. The storm was now almost two m-years long, over three terran years, but Sax was philosophical about it. John called him at Echus Overlook, and when John mentioned the cold nights he was experiencing Sax only said, “We’ll very likely have low temperatures for the greater part of the terraforming period. But warmer per se isn’t what we’re trying for. Venus is warm. What we want is survivable. If we can breath the air, I don’t care if it’s cold.”

Meanwhile it was cold, cold everywhere, the nights down to a hundred below every night, even on the equator. When John reached Underhill, a week after leaving Senzeni Na, he found there was a kind of pink ice covering the sidewalks; it was nearly invisible in the storm’s dim light, and walking around was a treacherous business. The people at Underhill spent most of their time indoors. John occupied a few weeks by helping the local bioengineering team field test a new fast snow algae. Underhill was crowded with strangers. Most of them were young Japanese or Europeans, who fortunately still used English to communicate with each other. John roomed in one of the old barrel vaults, near the northeast corner of the quadrant. The old quadrant was less popular than Nadia’s concourse, smaller and dimmer, and many of its vaults were now were used for storage. It was strange to walk the square of hallways, remembering the pool, Maya’s room, the dining hall-now all dark, and stacked with boxes. Those years when the first hundred had been the only hundred. It was getting hard to remember what that had been like.

He kept track through Pauline of the movements of quite a few people, the UNOMA investigating force among them. It was a not-very-rigorous surveillance, as it was not always easy to track the investigators, especially Houston and Chang and their crew, whom he suspected were going off-net deliberately. Meanwhile the spaceports’ arrival records gave more evidence every month that Frank had been right about them being only the tip of the iceberg; a lot of people coming down at Burroughs in particular were working for UNOMA without job specifications, and then spreading out to the mines and moholes and other settlements, and going to work for the local security heads. And their Terran employment records were very interesting indeed.

Often at the end of a session with Pauline John would leave the quadrant, and go for a walk outside, feeling disturbed and thinking hard. There was a lot more visibility than there had been; things were clearing up a bit out on the surface, though the pink ice still make walking tricky. It seemed the Great Storm was lessening. Wind speeds on the surface were only two or three times the pre-storm average of thirty kilometers per hour, and the dust in the air was sometimes little more than a kind of thick haze, turning the sunsets into blazing pastel swirls of pink, yellow, orange, red, and purple, with random streaks of green or turquoise appearing and disappearing, along with icebows, and sundogs, and occasional brilliant shafts of pure yellow light: nature at her most tasteless, transient and spectacular. And watching all that hazy color and movement John would be distracted from his thoughts, and climb the great white pyramid to have a look around, and then go back inside ready to start the fight again.

One evening after one of these sunset extravaganzas he climbed down the peak of the great pyramid, and walked slowly back toward Underhill-and then he spotted two figures climb out one of the garage side doors, and down a clear crawltube into a rover. There was something quick and furtive in their motion, and he stopped to look closer: they did not have their helmets on, and he recognized Houston and Chang by the backs of their heads and the size of their bodies. They moved with scurrying terran inefficiency into the rover, and drove toward him. John polarized his faceplate and started walking again, head down, trying to look like someone coming in from work, veering to the side a bit to increase the distance between him and them. The rover dove into a thick dust cloud and disappeared abruptly.
