“Well, like I said, there’s been some sabotage reported.”

Okakura was frowning through his faceplate. “But who? And why?”

“I don’t know. Anyone in your team seem to be having any psychological difficulties?”

“No.” Okakura’s face was carefully blank. Every group larger than five had someone experiencing difficulties, and Okakura’s little industrial town had a population of five hundred.

“This the sixth case I’ve seen,” John said. “Although none so close up.” He laughed. The image of the birdlike dot in the pink sky came back to him. “It would have been easy for someone to attach a bomb to a truck before it came down. Detonate it with a clock or an altimeter.”

“Reds, you mean.” Okakura was looking relieved. “We have heard of them. But it is…” He shrugged. “Crazy.”

“Yes.” John climbed gingerly off the wreck. They walked back across the floor of the shaft to the car they had come down in. Okakura was on another band, talking to people up top.

John stopped by the central pit to have a final look around. The sheer size of the shaft was hard to grasp; the muted light and vertical lines reminded him of a cathedral, but all the cathedrals ever built would have sat like dollhouses at the bottom of this great hole. The surreal scale made him blink, and he decided he had tilted his head back too long.

They drove up the road inscribed in the side wall to the first elevator, left the car and got in the cage. Up they went. Seven times they had to get out and walk across the wall road to the bottom of the next elevator. The ambient light grew to something more like ordinary daylight. Across the shaft he could see where the wall was scored by the double spiral of the two roads: thread-marks in an enormous screw hole. The shaft’s bottom had disappeared into the murk, he couldn’t even make out the truck.

In the last two elevators they ascended through regolith; first the megaregolith, which looked like cracked bedrock, and then the regolith proper, its rock and gravel and ice all hidden behind a concrete retainer, a smooth curved wall that looked like a dam, and was angled so far back that the final elevator was actually a cog rail train. They cranked up the side of this enormous funnel-Big Man’s bathtub drain, Okakura had said on the way down-and came finally to the surface, out into the sun.

Boone got out of the cog train and looked back down. The regolith retainer looked like the inner wall of a very smooth crater, with a two-laned road spiraling down it; but the crater had no floor. A mohole. He could see down the shaft a little way, but the wall was in shadow, and only the road spiraling down picked up any light, so that it appeared to be something like a freestanding staircase, descending through empty space to the planet’s core.

Three of the giant dump trucks ground slowly up the last stretch of the road, full of black boulders. These days it took them five hours to make the trip from the bottom of the shaft, Okakura said. Very little supervision, like most of the project, in both manufacture and operation. The inhabitants of the town only had to see to programming, deployment, maintenance, and troubleshooting. And, now, security.

The town, called Senzeni Na, was scattered over the floor of Thaumasia Fossae’s deepest canyon. Nearest to the hole was the industrial park; here most of the excavation equipment was manufactured, and the rock from the hole processed for its trace amounts of valuable metals. Boone and Okakura stepped into the rim station, changed out of their pressure suits into coppery jumpers, and entered one of the clear walktubes that connected all the buildings in the town. It was cold and sunny in the tubes, and everyone in them wore clothing with an outer layer of copper-colored foil, the latest in Japanese radproofing. Copper creatures, moving in clear tubes; it looked to Boone like a giant ant farm. Overhead the thermal cloud frosted into existence and shot up like steam from a valve, until it was caught by high winds and blown out in a long flattened contrail.

The town’s actual living quarters were built into the southeast wall of the canyon. A big rectangular section of the cliff had been replaced by glass; behind it was a tall open concourse, backed by five stories of terraced apartments.

They walked through the concourse and Okakura led him up to the town offices, on the fifth floor. A small crowd of concerned-looking people gathered in their wake, chattering to Okakura and among themselves. They all went through the office and out onto its balcony. John watched closely as Okakura described in Japanese what had happened. A number of his audience looked nervous, and most would not meet John’s eye. Had the near accident itself been enough to incur giri? It was important to make sure they didn’t feel publicly shown up, or anything like it. Shame was strong stuff for the Japanese, and Okakura was beginning to look desperately unhappy, as if he were deciding it had been his fault.

“Look, it could just as easily have been outsiders as someone from here,” John said boldly. He made some suggestions for future security. “The rim is a perfect barrier. Set up an alarm system, and a few people at the rim station could keep an eye on both the system and the elevators. A waste of time, but I guess we have to do it.”

Diffidently Okakura asked him if he knew anything about who might be responsible for the sabotage. He shrugged. “No idea, sorry. People opposed to the moholes, I guess.”

“But the moholes are dug,” one of them said.

“I know. I guess it’s symbolic.” He grinned. “But if a truck falls on someone, it would be a bad symbol.”

They nodded seriously. He wished he had Frank’s facility for languages, it would help to be able to communicate better with these people. They were hard to read; inscrutable and all that.

They wondered if he wanted to lie down.

“I’m okay,” he said. “It missed us. We’ll have to look into it, but today let’s just continue according to the schedule we had.”

So Okakura and several men and women led him on a tour of the town, and cheerfully he visited labs and meeting rooms, lounges and dining halls. He nodded and shook hands and said Hi until he was sure he had met over fifty percent of Senzeni Na’s inhabitants. Most had not yet heard of the incident in the hole, and all were pleased to meet him; happy to shake his hand, to speak with him, to show him something, to look at him. It happened everywhere he went, reminding him unpleasantly of the fishbowl years between his first trip and his second.

But he did his job. An hour’s work, then four hours of being The First Man On Mars: the usual ratio. And as afternoon darkened to evening, and the whole town gathered for a banquet in honor of his visit, he settled back and patiently played his part. That meant shifting into a good mood, no easy task that night. If fact he took a break and went back to the bathroom in his room, and swallowed a capsule manufactured by Vlad’s medical group in Acheron; it was a drug they had named omegendorph, a synthetic mix of all the endorphins and opiates they had found in the brain’s natural chemistry, and a better feel-good drug than Boone would have imagined possible.

He returned to the banquet much more relaxed. In fact filled with a little glow. He had escaped death, after all, and by running like a wild man! Some more endorphins were not inappropriate. He moved easily from table to table, asking questions as he went. This was what pleased people, what gave them the festival feeling that a meeting with John Boone should bring. John liked being able to do that, it was the part of his job that made celebrity tolerable; because when he asked questions, people leaped to answer like salmon in the stream. It was peculiar, really, as if people were seeking to right the imbalance they felt in the situation, in which they knew so much about him while he knew so little about them. So that with the right encouragment, often a single carefully-judged prompt, they would erupt with the most astonishing spills of personal information: witnessing, testifying, confessing.
