"Is there?" Michel put his ear to Sax's chest, listened for a time, hissed. "Some fluid in there, you're right."

"What were they doing to him?" Nirgal asked Spencer.

"They were talking to him while they had him under. You know, they have located several memory centers in the hippocampus very precisely, and with drugs and a very minute ultrasound stimulation, and fast MRI to track what they're doing... well, people just answer whatever questions they are asked, often at great length. They were doing that to Sax when the wind hit and they lost power. The emergency generator kicked in right away, but-" He gestured at Sax. "Then, or when we took him out of the apparatus..."

This was why Maya had killed Phyllis Boyle, then. The end of the collaborator. Murder among the First Hundred....

Well, Kasei muttered under his breath in the other car, it wouldn't be the first time. There were people who suspected Maya of arranging the a.s.sa.s.sination of John Boone, and Nirgal had heard of people who suspected that Frank Chalmers's disappearance might also have been her doing. The Black Widow, they called her. Nirgal had discounted these stories as malicious gossip, spread by people who obviously hated Maya, like Jackie. But certainly Maya now looked poisonously dangerous, sitting in her car glaring at the radio, as if considering breaking their silence to send word to the south: white-haired, hawk-nosed, mouth like a wound... it made Nirgal nervous just to get in the same car with her, though he fought against the sensation. She was one of his most important teachers after all, he had spent hours and hours absorbing her impatient instruction in math and history and Russian, learning her more than any of the subject material; and he knew very well that she did not want to be a murderer, that under her moods both bold and bleak (both manic and depressive) there writhed a lonely soul, proud and hungry. So that in yet another way this affair had become a disaster, despite their ostensible success.

Maya was adamant that they should all get down immediately into the southern polar region, to tell the underground what had happened.

"It is not so easy," Coyote said. "They know we were in Kasei Vallis, and since they had time to get Sax to talk, they probably know we'll be trying to get back south. They can look at a map as well as we can, and see that the equator is basically blocked, from west Tharsis all the way to the east of the chaoses."

"There's the gap between Pavonis and Noctis," Maya said.

"Yes, but there's several pistes and pipelines crossing that, and two wraps of the elevator. I've got tunnels built under all those, but if they're looking they might find some of them, or see our cars."

"So what are you saying?"

"I think we have to go around, north of Tharsis and Olympus Mons, and then down Amazonis, and cross the equator there."

Maya shook her head. "We need to get south fast, to let them know they've been found out."

Coyote thought about it. "We can split up," he said. "I've got a little ultralight plane stashed in a hideout near the foot of Echus Overlook. Kasei can lead you and Michel to it, and fly you back south. We'll follow by way of Amazonis."

"What about Sax?"

"We'll take him straight to Tharsis Tholus, there's a Bogdanovist med clinic there. That's only two nights away."

Maya talked it over with Michel and Kasei, never even glancing at Spencer. Michel and Kasei were agreeable, and finally she nodded. "All right. We're off south. Come down as quickly as you can."

They drove by night and slept by day, in their old pattern, and in two nights made their way across Echus Chasma to Tharsis Tholus, a volcanic cone on the northern edge of the Tharsis bulge.

There a Nicosia-cla.s.s tent town called Tharsis Tholus was located on the black flank of its namesake. The town was part of the demimonde: most of its citizens were living ordinary lives in the surface net, but many of them were Bogdanovists, who helped support Bogdanovist refuges in the area, as well as Red sanctuaries in Mareotis and on the Great Escarpment; and they helped other people in the town who had left the net, or been off it since birth. The biggest med clinic in town was Bogdanovist, and served many of the underground.

So they drove right up to the tent, and plugged into its garage, and got out. And soon a little ambulance car came and rushed Sax to the clinic, near the center of town. The rest of them walked down the gra.s.sy main street after him, feeling the roominess after all those days in the cars. Art goggled at their open behavior, and Nirgal briefly explained the demimonde to him as they walked to a cafe with some safe rooms upstairs, across from the clinic.

At the clinic itself they were already at work on Sax. A few hours after their arrival, Nirgal was allowed to clean up and change into sterile clothes, and then to go in to sit with him.

They had him on a ventilator, which was circulating a liquid through his lungs. One could see it in the clear tubes and the mask covering his face, looking like clouded water. It was an awful thing to see, as if they were drowning him. But the liquid was a perfluorocarbon-based mixture, and it transferred to Sax three times as much oxygen as air would have, and flushed out the gunk that had been acc.u.mulating in his lungs, and reinflated collapsed airways, and was spiked with a variety of drugs and medicines. The med tech working on Sax explained all this to Nirgal as she worked. "He had a bit of edema, so it's kind of a paradoxical treatment, but it works."

And so Nirgal sat, his hand on Sax's arm, watching the fluid inside the mask that was taped to Sax's lower face, swirling in and out of him. "It's like he's back in an ectogene tank," Nirgal said.

"Or," the med tech said, looking at him curiously, "in the womb."

"Yes. Being reborn. He doesn't even look the same."

"Keep that hand on him," the tech advised, and went away. Nirgal sat and tried to feel how Sax was doing, tried to feel that vitality struggling in its own processes, swimming back up into the world. Sax's temperature fluctuated in alarming little swoops and dives. Other medical people came in and held instruments against Sax's head and face, talking among themselves in low voices. "Some damage. Anterior, left side. We'll see."

The same tech came in a few nights later when Nirgal was there, and said, "Hold his head, Nirgal. Left side, around the ear. Just above it, yeah. Hold it there and... yeah, like that. Now do what you do."

"What?"

"You know. Send heat into him." And she left hastily, as if embarra.s.sed to have made such a suggestion, or frightened.

Nirgal sat and collected himself. He located the fire within, and tried running some of it into his hand, and across into Sax. Heat, heat, a tentative jolt of whiteness, sent into the injured green... then feeling again, trying to read the heat of Sax's head.

Days pa.s.sed, and Nirgal spent most of them at the clinic. One night he was coming back from the kitchens when the young tech came running down the hall to him, grabbing him by the arm and saying, "Come on, come on," and the next thing he knew he was down in the room, holding Sax's head, his breath short and all his muscles like wires. There were three doctors in there and some more techs. One doctor put out an arm toward Nirgal, and the young tech stepped in between them.

He felt something inside Sax stir, as if going away, or coming back- some pa.s.sage. He poured into Sax every bit of viriditas he could muster, suddenly terrified, stricken with memories of the clinic in Zygote, of sitting with Simon. That look on Simon's face, the night he died. The perfluorocarbon liquid swirled in and out of Sax, a quick shallow tide. Nirgal watched it, thinking about Simon. His hand lost its heat, and he couldn't bring it back. Sax would know who it was with hands so warm. If it mattered. But as it was all he could do... he exerted himself, pushed as if the world were freezing, as if he could pull back not only Sax but also Simon, if he pushed hard enough. "Why, Sax?" he said softly into the ear by his hand. "But why? Why, Sax? But why? Why, Sax? But why? Why, Sax? But why?"

The perfluorocarbon swirled. The overlit room hummed. The doctors worked at the machines and over Sax's body, glancing at each other, at Nirgal. The word why why became nothing but a sound, a kind of prayer. An hour pa.s.sed and then more hours, slow and anxious, until they fell into a kind of timeless state, and Nirgal couldn't have said whether it was day or night. Payment for our bodies, he thought. We pay. became nothing but a sound, a kind of prayer. An hour pa.s.sed and then more hours, slow and anxious, until they fell into a kind of timeless state, and Nirgal couldn't have said whether it was day or night. Payment for our bodies, he thought. We pay.

One evening, about a week after their arrival, they pumped Sax's lungs clear, and took the ventilator off. Sax gasped loudly, then breathed. He was an air-breather again, a mammal. They had repaired his nose, although it was now a different shape, almost as flat as it had been before his cosmetic surgery. His bruises were still spectacular.

About an hour after they took the ventilator off, he regained consciousness. He blinked and blinked. He looked around the room, then looked very closely at Nirgal, clutching his hand hard. But he did not speak. And soon he was asleep.

Nirgal went out into the green streets of the small town, dominated by the cone of Tharsis Tholus, rising in black and rust majesty to the north, like a squat Fuji. He ran in his rhythmic way, around and around the tent wall as he burned off some of his excess energy. Sax and his great unexplainable...

In rooms over the cafe across the street, he found Coyote hobbling restlessly from window to window, muttering and singing wordless calypso tunes. "What's wrong?" Nirgal said.

Coyote waggled both hands. "Now that Sax is stabilized, we should get out of here. You and Spencer can tend to Sax in the car, while we drive west around Olympus."

"Okay," Nirgal said. "When they say Sax is ready."

Coyote stared at him. "They say you saved him. That you brought him back from the dead."

Nirgal shook his head, frightened at the very thought. "He never died."

"I figured. But that's what they're saying." Coyote regarded him thoughtfully. "You'll have to be careful.

They drove by night, contouring around the slope of north Tharsis, Sax propped on the couch in the compartment behind the drivers. Within hours of their departure Coyote said, "I want to hit one of the mining camps run by Subarashii in Ceraunius." He looked at Sax. "It's okay with you?"

Sax nodded. His racc.o.o.n bruises were now green and purple.

"Why can't you talk?" Art asked him.

Sax shrugged, croaked once or twice.

They rolled on.

From the bottom of the northern side of the Tharsis bulge there extends an array of parallel canyons called the Ceraunius Fossae. There are as many as forty of these fractures, depending on how you count them, as some of the indentations are canyons, while others are only isolated ridges, or deep cracks, or simply corrugations in the plain- all running north and south, and all cutting into a metallogenic province of great richness, a basalt ma.s.s rifted with all kinds of ore intrusions from below. So there were a lot of mining settlements and mobile rigs in these canyons, and now, as he contemplated them on his maps, Coyote rubbed his hands together. "Your capture set me free, Sax. Since they know we're out here anyway, there's no reason we shouldn't put some of them out of business, and grab some uranium while we're at it."

So he stopped one night at the southern end of Tractus Catena, the longest and deepest of the canyons. Its beginning was a strange sight- the relatively smooth plain was disrupted by what looked like a ramp that cut into the ground, making a trench about three kilometers wide, and eventually about three hundred meters deep, running right over the horizon to the north in a perfectly straight line.

They slept through the morning, and then spent the afternoon sitting in the living compartment nervously, looking at satellite photos and listening to Coyote's instructions.

"Is there a chance we'll kill these miners?" Art asked, pulling at his big whiskery jaw.

Coyote shrugged. "It might happen."

Sax shook his head back and forth vehemently.

"Not so rough with your head," Nirgal said to him.

"I agree with Sax," Art said quickly. "I mean, even setting aside moral considerations, which I don't, it's still stupid just as a practical matter. It's stupid because it makes the a.s.sumption that your enemies are weaker than you, and will do what you want if you murder a few of them. But people aren't like that. I mean, think about how it will fall out. You go down that canyon and kill a bunch of people doing their jobs, and later other people come along and find the bodies. They'll hate you forever. Even if you do take over Mars someday they'll hate you, and do anything they can to screw things up. And that's all you will have accomplished, because they'll replace those miners quick as that."

Art glanced at Sax, who was sitting up on the couch, watching him closely. "On the other hand, say you go down there and do something that causes those miners to run into their emergency shelter and then you lock them in the shelter and wreck their machines. They call for help, they hang out there, and in a day or two somebody comes to rescue them. They're mad but also they're thinking we could be dead, those Reds wrecked our stuff and were gone in a flash, we never even saw them. They could have killed us but they didn't. And the people who rescued them will be thinking the same. And then later on, when you've taken over Mars or when you're trying to, they remember and they all dive off into hostage syndrome and start rooting for you. Or working with you."

Sax was nodding. Spencer was looking at Nirgal. And then they all were, all but Coyote, who was looking down at the palms of his hands, as if reading them. And then he looked up, and he too was looking at Nirgal.

For Nirgal it was simple, and he regarded Coyote with some concern. "Art's right. Hiroko will never forgive us if we start killing people for no reason."

Coyote's face twisted, as if in disgust for their softness. "We just killed a bunch of people in Kasei Vallis," he said.

"But that was different!" Nirgal said.

"How so?"

Nirgal hesitated, unsure, and Art said quickly, "Those were a bunch of police torturers who had your buddy and were microwaving his brain. They got what was coming to them. But these guys down this canyon are just digging up rocks."

Sax nodded. He was staring at them all with the utmost intensity, and it seemed certain that he understood everything, and was deeply engaged in it; but mute as he was, it was hard to be sure.

Coyote stared hard at Art. "Is this a Praxis mine?"

"I don't know. I don't care, either."

"Hmm. Well-" Coyote looked at Sax; then at Spencer; then at Nirgal, who could feel his cheeks burning. "All right then. We'll try it your way."

And so at the end of the day Nirgal climbed out of the rover with Coyote and Art. The sky above was dark and starry, the western quadrant still purple, casting a florid light in which everything was quite visible but at the same time unfamiliar. Coyote led the way, and Art and Nirgal followed him closely. Through his faceplate Nirgal could see that Art's eyes were pressing gla.s.s.

The floor of Tractus Catena was broken at one point by a transverse fault system called Tractus Traction, and the trellis fracturing in this zone had formed a system of creva.s.ses impenetrable to vehicles. The Tractus miners reached their camp from the canyon wall above it, descending in elevators. But Coyote said it was possible to walk through Tractus Traction, following a path of connecting creva.s.ses he had marked for himself. Many of his resistance actions involved crossing "impa.s.sable" terrain like this, making possible some of his more legendary impossible visitations, and sending him through badlands no one else had ever even approached. And with Nirgal to run some of the raids, they had performed some truly miraculous-seeming ventures- just by getting out and traveling on foot.

So they jogged down the canyon floor, in the steady Martian lope that Nirgal had perfected, and had tried with partial success to teach to Coyote. Art was not graceful- his stride was too short, and he stumbled frequently- but he kept up. Nirgal began to feel the loose joy of running, the boulder ballet of it, the rapid crossing of long stretches of land under his own power. Also the rhythmic breathing, the bounce of his air tank on his back, the trancelike state that he had learned over the years, with help from the issei Nanao, who had been taught lung-gom lung-gom on Earth by a Tibetan adept. Nanao claimed that some of the old on Earth by a Tibetan adept. Nanao claimed that some of the old lung-gom-pas lung-gom-pas had had to carry weights to keep from flying away, and on Mars it seemed entirely possible. The way he could fly over rocks was exhilarating, a kind of rapture. had had to carry weights to keep from flying away, and on Mars it seemed entirely possible. The way he could fly over rocks was exhilarating, a kind of rapture.

He had to restrain himself. Neither Coyote nor Art knew lung-gom lung-gom, and they couldn't keep up, though they were both pretty good, Coyote for his age, Art for his recent arrival on Mars. Coyote knew the land, and ran in short mincing dance steps, efficient and clean. Art bombed over the landscape like a badly programmed robot, staggering often as he hit wrong in the starlight, but keeping up a pretty good head of steam nevertheless. Nirgal ranged in front of them like a dog. Twice Art went down in a cloud of dust and Nirgal ran over to check on him, but both times Art got up jogging, and in their intercom silence he only waved to Nirgal and ran on.

After half an hour's run down the canyon, which was so straight that it seemed cut by design, cracks appeared on the ground, and quickly deepened and connected up with one another, until progress over the canyon floor proper would have been impossible, as it was now the plateau tops of a collection of islands. The deep slots separating these islands were in places only two or three meters wide, but thirty or forty meters deep.

Walking through these generally flat-floored alleys was a strange business, but Coyote led the way through the maze without delaying at any of the many forks, following a path only he knew, turning left and right a score of times. One slot was so narrow they could touch both walls at once, and they had to sc.r.a.pe through a turn.

When they came out the northern side of the creva.s.se maze, emerging from a draw in the riven steep escarpment which was the end of the plateau islands, a small tent stood before them against the western canyon wall. Its arc of fabric glowed like the bulb of a dusty lamp. Within the tent were mobile trailers, rovers, drills, earthmovers, and other mining equipment. It was a uranium mine, called Pitchblende Alley, because this lower section of the canyon was floored with a pegmat.i.te extremely rich in uraninite. It was a very productive mine, and Coyote had heard that the processed uranium stockpiled at it during the years between elevators had not yet been shipped out.

Now Coyote ran over the canyon floor toward the tent, and Nirgal and Art followed. There was no one visible inside the tent; the only illumination was provided by a few night lights, and the lit windows of a big trailer set near the center of things.

Coyote walked right up to the tent's nearest lock gate, and the other two followed him. He plugged his wristpad jack into the keyhole by the lock gate, and began to tap on his wristpad. The outer lock door opened. No alarms seemed to go off; no figures appeared out of the door of the trailer. They got in the lock, closed the outer door, waited for the lock to suck and pump, then opened the inner door. Coyote ran toward the settlement's little physical plant, beside the trailer; Nirgal went for the living quarters, hopping up the steps to the trailer's door. He held one of Coyote's "locking bars" under the door handle, turned the dial that released the fixative, and pushed the bar against the door and wall of the trailer. The trailer was made of a magnesium-based alloy, and the polymer fixative would make what was in effect a ceramic bond between the locking bar and the trailer, so that the door would be stuck. He ran around the trailer and did the same to the other door, then dashed back toward the gate, feeling his blood fly through him as if it were pure adrenaline. It was so much like a prank that he had to consciously remember the explosive charges that Coyote and Art were distributing through the settlement, in warehouses, against the tent fabric, and in the parking lot for the mining behemoths. Nirgal joined them in running from vehicle to vehicle, climbing the stairs on their sides, opening doors manually or electronically, tossing small boxes Coyote had provided into the cabs or cabins.

But there were also hundreds of tons of processed uranium that Coyote wanted to haul away. This was impossible, unfortunately. They did run over to a warehouse, however, where they filled a number of the mine's own robot trucks with loads, and programmed them with instructions to head off into the canyonlands to the north, burying loads in regions where the apat.i.te concentrations might be high enough to disguise the boxed uranium's radioactivity, and make the loads hard to relocate. Spencer had doubted this strategy would work, but Coyote said it beat leaving the uranium at the mine, and all of them were happy to help in any plan that would keep him from putting tons of uranium in the storage hold of their boulder car, radproof containers or not.

When that was done they ran back to the gate, and got back outside, and ran hard. Halfway to the escarpment they heard a series of pops and booms from the tent, and Nirgal glanced over his shoulder, but saw nothing different- the tent was still mostly dark, the trailer windows lit.

He turned and ran on, feeling as if he were flying, and was astonished to see Art racing over the canyon floor ahead of him, every stride a huge wild leap, bounding like some cheetah-bear all the way to the escarpment, where he had to wait for Coyote to catch up and lead them back through the creva.s.se maze. Once out of it he took off again, so fast that Nirgal decided to try to catch him, just to feel how fast it was. He got into the rhythm of the sprint, pressing harder and harder, and as he pa.s.sed Art he saw that his own springbok strides were almost twice as long as Art's even in sprint mode, where both their legs were pumping as fast as possible.

They got to the boulder car long before Coyote, and waited for him in the lock, catching their breath, grinning through their faceplates at each other. A few minutes later Coyote was there and in with them, and Spencer had the rover moving, with the timeslip just past, and six more hours of night to drive in.

Inside they laughed hard at Art's mad run, but he only grinned and waved them off. "I wasn't scared, it's this Martian gravity I tell you, I was just running the way I usually would but my legs were leaping along like a tiger! Amazing."

They rested through the day, and after dark they were off again. They pa.s.sed the mouth of a long canyon that ran from Ceraunius to Jovis Tholus; it was an oddity in that it was neither straight nor sinuous, and was called Crooked Canyon. When the sun rose they were hidden on the ap.r.o.n of Crater Qr, just north of Jovis Tholus. Jovis Tholus was a bigger volcano than Tharsis Tholus, bigger in fact than any volcano on Earth, but it was located on the high saddle between Ascraeus Mons and Olympus Mons, and both were visible on skysills to east and west, bulking like vast plateau continents, and making Jovis seem compact, friendly, comprehensible- a hill you could walk up if you wanted to.

That day Sax sat and stared silently at his screen, tapping at it tentatively and getting a random a.s.sortment of texts, maps, diagrams, pictures, equations. He tilted his head at each, with no sign of recognition. Nirgal sat down beside him. "Sax, can you hear what I'm saying?"

Sax looked at him.

"Can you understand my words? Nod if you understand."

Sax tilted his head to the side. Nirgal sighed, held by that inquisitive look. Sax nodded, hesitantly.

That night Coyote drove west again, toward Olympus, and near dawn he directed the rover right up to a wall of pocked and riven black basalt. This was the edge of a tableland cut by innumerable narrow twisting ravines, like Tractus Traction only on a much larger scale, creating a badlands like an immense expansion of the Traction's maze. The tableland was a fan of broken ancient lava, the remnant of one of the earliest flows from Olympus Mons, capping softer tuff and ash from even earlier eruptions. Where the wind-cut ravines had worn deep enough, their bottoms broke through into the layer of softer tuff, so that some ravines were narrow slots with tunnels at their bottoms, rounded by eons of wind. "Like upside-down keyholes," Coyote said, though Nirgal had never seen a keyhole remotely like these shapes.

Coyote drove the rover right into one of the black-and-gray tunnel ravines. Several kilometers up the tunnel he stopped the car, beside a wall of tenting that cut off a kind of embolism in the tunnel, a widened outer curve.

This was the first hidden sanctuary that Art had ever seen, and he looked suitably startled. The tent was perhaps twenty meters tall, containing a section of the curve a hundred meters long; Art exclaimed over the size of it until Nirgal had to laugh. "Someone else is already here using it," Coyote said, "so be quiet for a second."

Art nodded quickly, and leaned over Coyote's shoulder to hear what he was saying over the intercom. Parked before the tent lock was another car, just as lumpish and rocky as their own. "Ah," said Coyote, pushing Art back. "It's Vijjika. They'll have oranges, and maybe some kava. We'll have a party this morning for sure."

They rolled up to the tent lock, and a coupler tube reached out and clamped around their exterior door. When all the lock doors were opened they made their way into the tent, bending and shuffling to carry Sax through the tube with them.

They were met inside by eight tall, dark-skinned people, five women and three men- a loud group, happy to have company. Coyote introduced them all, although Nirgal knew Vijjika from the university in Sabishii, and gave her a big hug. She was pleased to see him again, and led them all back to the smooth curve of the cliff wall, into a clearing between trailers, under a skylight provided by a vertical crack in the old lava. Under this shaft of diffuse daylight, and the even more diffuse light from the deep ravine outside the tent, the visitors sat on broad flat pillows around low tables, while several of their hosts went to work at a clutch of round-bellied samovars. Coyote was talking with acquaintances, catching up on the news. Sax looked around, blinking, and Spencer, beside him, did not look much less confused; he had been living in the surface world since '61, and his knowledge of the sanctuaries must have been almost entirely secondhand. Forty years of a double life; it was no wonder he looked stunned.

Coyote went to the samovars, and began handing out tiny cups from a freestanding cabinet. Nirgal sat next to Vijjika, an arm around her waist, soaking in her warmth and buzzing with the long contact of her leg against his. Art sat down on her other side, his broad face thrust into the conversation like a dog's. Vijjika introduced herself to him, and shook his hand; he clasped her long delicate fingers in his big paw as if he wanted to kiss them. "These are Bogdanovists," Nirgal explained to Art, laughing at his expression and handing him one of the little ceramic cups from Coyote. "Their parents were prisoners in Korolyov before the war."

"Ah," Art said. "We're a long way from there, right?"

Vijjika said, "Yes, well, our parents took the Transmarineris Highway north, just before it was flooded, and eventually they came here. Here, take that tray from Coyote and go pa.s.s out cups, and introduce yourself to everyone."

So Art made the rounds, and Nirgal caught up on news with Vijjika. "You won't believe what we've found in one of these tuff tunnels," she told him. "We've become most fantastically rich." Everyone had their cup, so they all paused for a moment and took their first sips together, then after some whoops and a general smacking of the lips they went back to their conversations. Art returned to Nirgal's side.
