“Like breaking and entering.”

“If we determine that we need to check your quarters, or your records, to pursue our investigation, than we’re going to do that. We have that authority.”

“I say you don’t,” John said arrogantly, and snapped his fingers in the man’s face.

“We are going to search your rooms,” Houston said, articulating each word very carefully.

“Get away,” Boone said contemptuously, and jerked at the other two and waved them back. He laughed, lip curled with scorn: “That’s right, go! Get out of here, you incompetents-go back and read the regs on search and seizure!”

He went in his room and closed the door behind him.

He paused. It sounded like they were leaving, but either way he had to act like he didn’t care. He laughed, and went to the bathroom and took some more painkillers.

They hadn’t yet gotten to the closet, which was lucky; it would have been hard to explain the torn walker without telling the truth, and that would have been messy. Curious how tangled things got when you concealed the fact that someone had tried to kill you. That made him pause. The attempt had been pretty clumsy, after all. There must have been a hundred more effective ways to kill someone out in a walker on Mars. So if they were just trying to scare him, or were perhaps hoping that he would try to conceal the attack, so that they could find him lying, and then have something on him…

He shook his head, confused. Occam’s razor, Occam’s razor. The detective’s pimary tool. If someone attacks you they mean you harm, that was the basic, the fundamental fact. It was important to find out who the attackers were. And so on. The painkillers were strong, and the omegandorph was wearing off. It was getting hard to think. It was going to be a problem disposing of the walker; the helmet in particular was a big bulky thing. But now he was into it, and there was no graceful way out. He laughed; he knew he would think of something eventually.

He wantedto talk to Arkady. A call determined that Arkady had finished the gerontological treatment in Acheron with Nadia, however, and had gone up to Phobos. John had still never visited the fast little moon. “Why don’t you come on up and see it?” Arkady said over the phone. “Better to talk in person, yes?”

“Okay.”

He hadn’t been in space since the landing from the Ares twenty-three years before, and the familiar sensations of acceleration and weightlessness brought on an unexpected bout of nausea. He told Arkady about it as they docked with Phobos, and Arkady said, “It always used to happen to me, until I started drinking vodka right before takeoff.” He had a long phsyiological explanation for this, but the details began to pull John back over the edge and he cut him off. Arkady laughed; the gerontological treatment had given him its usual post-operative lift, and he had been a happy man to begin with; he didn’t look like he would be sick again for a thousand years.

Stickney turned out to be a bustling little town, the crater’s concrete dome lined with the latest heavy-duty radiation proofing, and the floor of the crater terraced in concentric rings down to a bottom plaza. The rings alternated between parks and two-storied buildings with gardens on their roofs. There were nets in the air for people who lost control of their leaps across the city, or took off by accident; escape velocity was only fifty kilometers per hour, so it was almost possible to run right off the moon. Just under the dome foundation John spotted a small version of the exterior circumnavigating train, running horizontally compared to the buildings of the town, and moving at a speed that returned its passengers to a sensation of Martian gravity. It stopped four times a day to take people on, but if John took refuge in it that would only delay his acclimatization, so he went to the guest room assigned to him, and miserably waited out the nausea. It seemed he was a planet dweller now, a Martian for good, so that leaving it was pain. Ridiculous but true.

The next day he felt better, and Arkady took him on a tour of Phobos. The interior was honeycombed with tunnels, galleries, drifts, and several enormous open chambers, many of them still being enlarged, mined for water and fuel. Most of the interior tunnels inside the moon were smooth functional tubes, but the interior rooms and some of the big galleries had been built according to Arkady’s socio-architectural theories, and he showed John around some of these: circular hallways, mixed work and recreation areas, terracing, etched metallic walls, all features that had become standard during Mars’s crater-oriented phase of construction, but of which Arkady was still proud.

Three of the little surface craters on the side opposite to Stickney had been domed with glass and filled with villages which had a view of the planet rushing beneath them-views never available from Stickney, as Phobos’s long axis was permanently aligned toward Mars, with the big crater always pointed away. Arkady and John stood in Semenov, looking up through the dome at Mars, which filled half the sky and was shrouded by its dust clouds, all its features obscured. “The Great Storm,” Arkady said. “Sax must be going mad.”

“No,” John said. “A thing of the moment, he says. A glitch.”

Arkady hooted. Already the two of them had fallen back into their old easy camaraderie, the feeling that they were equals, brothers from way back. Arkady was the same as ever, laughing, joking, a great kidder, ideas and opinions flooding out of him, confident in a way that John enjoyed immensely, even now, when he was sure many of Arkady’s ideas were wrong, and even dangerous.

“Sax is probably right, in fact,” Arkady said. “If those aging treatments work, and we are living decades longer than previously, it will certainly cause a social revolution. Shortness of life was a primary force in the permanence of institutions, strange though it is to say it. But it is so much easier to hold onto whatever short-term survival scheme you have, rather than risking it all on a new plan that might not work-no matter how destructive your short-term plan might be for the following generations. Let them deal with it, you know. And really, to give them their due, by the time people learned the system they were old and dying, and for the next generation it was all there, massive and entrenched and having to be learned all over again. But look, if you learn it, and then stare at it for fifty more years, you will eventually be saying, Why not make this more rational? Why not make it closer to our heart’s desire? What’s stopping us?”

“Maybe that’s why things are getting so strange down there,” John said. “But somehow I don’t think these people are taking the long view.” He gave Arkady a quick account of the sabotage situation, and ending it by saying boldly: “Do you know who’s doing it, Arkady? Are you involved?”

“What, me? No, John, you know me better than that. These destructions are stupid. The work of reds, from the look of it, and I am no red. I don’t know exactly who is doing it. Probably Ann does, have you asked her?”

“She says she doesn’t know.”

Arkady cackled. “Still my same John Boone! I love it. Look here, my friend, I will tell you why these things are happening, and then you can work at it systematically, and perhaps see more. Ah, here’s the subway to Stickney-come on, I want to show you the infinity vault, it’s really a nice piece of work.” He led John to the little subway car, and they floated down a tunnel to near the center of Phobos, where the car stopped and they got out. They pushed across the narrow room, and pulled themselves down a hall; John noted that his body had adjusted to the weightlessness, that he could float and keep his trim again. Arkady led him into an expansive open gallery, which on first glance appeared to be too large to be contained inside of Phobos: floor, wall and ceiling were paneled in faceted mirrors, and each round slab of polished magnesium had been angled so that anyone in its microgravity space was reflected in thousands of infinite regresses.
