So he spent the evening learning about life at Senzeni Na (“Means, what have we done?” Quick grin.) And afterwards he was led to his big guest suite, the rooms thick with live bamboo, the bed seemingly hacked out of a stand of it. When he was alone he connected his code box to the phone, and called Sax Russell.

* * *

Russell was at Vlad’s new headquarters, a research complex built into a dramatic fin ridge in the Acheron Fossae north of Olympus Mons. Sax spent all his time there now, studying genetic engineering like an undergrad; he had become convinced that biotechnology was the key to terraforming, and he was determined to educate himself to the point where he could contribute actively to that part of the campaign, despite the fact that all his training was in physics. Modern biology was notoriously gooey, and a lot of physicists hated it; but the people at Acheron said Sax was a quick learner, and John believed it. Sax himself made little snicking noises at his own progress, but it was clear he was deep in. He talked about it all the time, “It’s the crux,” he would say, “we need the water out of the ground and the carbon dioxide out of the air, and it’s going to take biomass to do both.” And so he slaved at the screens and in the labs.

He listened to Boone’s report with his usual impassivity. Such a parody of the scientist, John thought. He even wore a lab coat. Seeing his characteristic blink made John think of a story he had heard one of Sax’s assistants tell, to a laughing audience at a party: in a secret experiment gone awry, a hundred lab rats that had been injected with an intelligence booster became geniuses. They revolted and escaped from their cages, and captured their principal investigator, and strapped him down and retro-injected all their minds into his body, using a method they invented on the spot-and that scientist was Saxifrage Russell, white-coated, blinking, twitching, inquisitive, lab-bound. His brain the sum of a hundred hyperintelligent rats, “and named for a flower like lab rats are, it’s their little joke, see?”

It explained a lot. John smiled as he finished his report, and Sax cocked his head at him curiously. “Do you think this truck was meant to kill you?”

“I don’t know.”

“How do the people there seem?”

“Scared.”

“Think they’re in on it?”

John shrugged. “I doubt it. They’re probably just worried about what happens next.”

Sax flicked a hand out. “Sabotage like that won’t make the slightest dent in the project,” he said mildly.

“I know.”

“Who’s doing this, John?”

“I don’t know.”

“Could it be Ann, do you think? Has she become another prophet, like Hiroko or Arkady, with followers and a program and the like?”

“You have followers and a program too,” John reminded him.

“But I’m not telling my followers to wreck things and try to kill people.”

“Some people think you’re trying to wreck Mars. And people will certainly die as a result of terraforming, in accidents.”

“What are you saying?”

“Just reminding you. Trying to get you to see why someone might do this.”

“So you do think it’s Ann.”

“Or Arkady, or Hiroko, or someone we’ve never heard of in one of the new colonies. There are a lot of people here now. A lot of factions.”

“I know.” Sax walked over to a countertop, drained his battered old coffee mug. Finally he said, “I’d like you to try to find out who it is. Go where you need to go. Go talk to Ann. Reason with her.” There was a plaintive note in his voice: “I can’t even talk to her anymore.”

John stared at him, surprised at the display of emotion. Sax took this silence for reluctance, and went on: “I know it isn’t exactly your thing, but everyone will talk to you. You’re practically the only one left we can say that about. I know you’re doing the mohole work, but you can get your team to do your part of that, and keep visiting the moholes as part of this inquiry. There really isn’t anyone else who can do it. There’s no real police to turn to. Although if things keep happening, UNOMA will provide some.”

“Or the transnationals.” Boone considered it. The sight of that truck, falling out of the sky… “All right. I’ll go talk to Ann, anyway. After that we should get together and talk about security for all the terraforming projects. If we can stop anything more from happening, that will keep UNOMA out.”

“Thanks, John.”

Boone wandered out onto his suite’s balcony. The concourse was filled with Hokkaido pines, the chilled air stiff with resin. Copper figures walked below, among the tree trunks. Boone considered the new situation. For ten years now he had worked for Russell on terraforming, managing the moholes and doing PR and the like, and he enjoyed the work; but he wasn’t on the cutting edge of any of the sciences involved, and so he was out of the decision-making loop. He knew that many people thought of him as a figurehead only, a celebrity for consumption back on Earth; a dumb space jock who had gotten lucky once, and was living off that for good. That didn’t bother John; there were always knee-high people hacking away, trying to get everyone down to their size. That was okay, especially since in his case they were wrong. His power was considerable, although perhaps only he could see the full extent of it, as it consisted of an endless succession of face-to-face meetings, of the influence he had over what people chose to do. Power wasn’t a matter of job titles, after all. Power was a matter of vision, persuasiveness, freedom of movement, fame, influence. The figurehead stands at the front, after all, pointing the way.

Still, despite all that, there was something to be said for this new task. He could feel that already. It would problematic, difficult, perhaps risky… above all, challenging. A new challenge; he liked that. Going back into his suite, getting into bed (John Boone Slept Here!) it occurred to him that now he was going to be not only the first man on Mars, but the first detective. He grinned at the thought, and the last action of the omegandorph set his nerves aglow.

Ann Clayborne was doing a survey in the mountains surrounding the Argyre Basin, which meant he could check out a glider and fly from Senzeni Na to her. So early the next morning he took the elevator balloon up the mooring mast to the stationary dirigible floating over the town, exulting as he rose in the ever-expanding view of the big Thaumasia canyons. From the dirigible he lowered himself into the cockpit of one of the gliders hooked to its underside. After securing himself he unhooked, and the glider dropped like a stone until he ran it into the mohole thermal, which tossed it violently upward. He fought for control and banked the big gossamer craft into a steep rising gyre, whooping as he battled the intense buffeting; it was like riding a soap bubble over a bonfire!

At five thousand meters the plume cloud flattened and spread out to the east. John swooped out of his spiral and headed southeast, playing with the glider as he went to get a feel for it. He would have to ride the winds carefully to make it to Argyre.

He aimed into the sun’s smeary yellow blaze. Wind keened over the wings. The land below him was a dark rough orange, shading to a very light orange at the horizon. The southern highlands were wildly pocked in every direction, with the raw, primordial, lunar look that saturation cratering always had. John loved flying over it, and he piloted unconsciously, concentrating on the land below. It was precious to sit back and fly, feeling the wind as if under his elbows, watching the land and not thinking a thing. He was sixty-four years old in this year 2047 (or “m-year 10” as he usually thought of it), and he had been the most famous man alive for almost thirty of those years; and nowadays he was happiest when he was alone, and flying.
