CHAPTER ONE

In the summer of his twelfth year—the summer the stars began to fall from the sky—the boy Isaac discovered that he could tell east from west with his eyes closed.

Isaac lived at the edge of the Great Inland Desert, on the continent of Equatoria, on the planet that had been appended to the Earth by the inscrutable beings called the Hypotheticals. People had given the planet a whole panoply of grandiose or mythological or coolly scientific names, but most simply called it the New World, in any of a hundred or more languages, or Equatoria, after its most widely settled continent. These were things Isaac had learned in what passed for school.

He lived in a compound of brick and adobe, far from the nearest town. He was the only child at the settlement. The adults with whom he lived preferred to keep a careful distance between themselves and the rest of the world. They were special, in ways they were reluctant to discuss. Isaac, too, was special. They had told him so, many times. But he wasn't sure he believed them. He didn't feel special. Often he felt much less than special.

Occasionally the adults, especially Dr. Dvali or Mrs. Rebka, asked Isaac whether he was lonely. He wasn't. He had books, he had the video library to fill his time. He was a student, and he learned at his own pace—steadily if not quickly. In this, Isaac suspected, he was a disappointment to his keepers. But the books and videos and lessons filled his time, and when they were unavailable there was the natural world around him, which had become a kind of mute, indifferent friend: the mountains, gray and green and brown, sloping down to this arid plain, the edge of the desert hinterland, a curdled landscape of rock and sand. Few things grew here, since the rain came only in the first months of spring and sparsely even then. In the dry washes there were lumpish plants with prosaic names: barrel cucumbers, leather vines. In the courtyard of the compound a native garden had been planted, cactus feathery with purple flowers, tall nevergreens with weblike blossoms that extracted moisture from the air. Sometimes a man named Raj irrigated the garden from a pump that ran deep into the earth, and on those mornings the air smelled of mineral-rich water: a steely scent that carried for kilometers. On watering day, rock shrews would burrow under the fence and tumble comically across the tiled courtyard.

Isaac's days passed in gentle sameness early in the summer of his twelfth year, as his days had always passed, but that sleepy peace came to an end the day the old woman arrived.

She came, remarkably, on foot.

Isaac had left the compound that afternoon and climbed a small distance up the foothills, to a granite shelf that jutted from the slope of a ridge like a ship's prow from a pebbly sea. The afternoon sun had warmed the rock to a fine, fierce heat. Isaac, with his wide-brimmed hat and white cotton shirt to protect him from the burning light, sat under the lip of the ridge where there was still shade, watching the horizon. The desert rippled in rising waves of furnace air. He was alone and motionless—afloat in heat, a castaway on a sere raft of stone—when the woman appeared. At first she was just a dot down the unpaved road that led from the distant towns where Isaac's keepers went to buy food and supplies. She moved slowly, or seemed to. Nearly an hour passed before he could identify her as a woman—then an old woman—then an old woman with a pack on her back, a bow-legged posture, and a dogged, determined stride. She wore a white robe and a white sun hat.

The road passed close to this rock, almost directly beneath it, and Isaac, who didn't want to be seen, though he could not say why, scooted behind a boulder and crouched there as she approached. He closed his eyes and imagined he felt the bulk and weight of the land beneath him, the old woman's two feet tickling the skin of the desert like a beetle on the body of a slumbering giant. (And he felt another presence, deep in that earth, a quiescent behemoth stirring in its long sleep far to the west…)

The old woman paused beneath the shelf of rock as if she could see him in his hiding place. Isaac was aware of the break in the rhythm of her shuffling steps. Or maybe she had innocently paused to sip water from a canteen. She said nothing. Isaac held himself very still, something he was good at.

Then her steps resumed. She walked on, leaving the road where a trail bent toward the compound. Isaac lifted his head and looked after her. She was many meters away now, the long light of the afternoon drawing her shadow alongside her like a leggy caricature. As soon as he saw her she paused and turned back, and for a moment it seemed as if their eyes met, and Isaac hastily ducked away, uncertain whether he had been seen. He was startled by the accuracy of her gaze and he remained hidden for a long time, until the sunlight angled deep into the mountain passes. He hid even from himself, quiet as a fish in a pool of memory and thought.

The old woman reached the compound's gates and went inside and stayed there. Before the sky grew wholly dark, Isaac followed her. He wondered if he would be introduced to the woman, perhaps at dinner.

Very few outsiders came to the compound. Of those who came, most came to stay.

After Isaac had bathed and put on clean clothes he went to the dining room.

This was where the entire community, all thirty of the adults, gathered every evening. Morning and afternoon meals were impromptu, could be taken at any time as long as you were willing to do your own work in the kitchen, but dinner was a collective effort, always crowded, inevitably noisy.

Usually Isaac enjoyed hearing the adults talk among themselves, though he seldom understood what they said unless it was trivial: whose turn it was to go to town for provisions, how a roof might be repaired or a well improved. More often, since the adults were mainly scientists and theoreticians, their talk turned to abstract matters. Listening, Isaac had retained few of the details of their work but something of its general content. There was always talk of time and stars and the Hypotheticals, of technology and biology, of evolution and transformation. Although these conversations usually pivoted on words he couldn't understand, they had a fine and lofty sound about them. The debates—were the Hypotheticals properly called beings, conscious entities, or were they some vast and mindless process?—often grew heated, philosophies defended and attacked like military objectives. It was as if in some nearby but inaccessible room the universe itself was being taken apart and reassembled.

Tonight the murmur was subdued. There was a newcomer present: the old woman from the road. Isaac, bashfully taking a seat between Dr. Dvali and Mrs. Rebka, cast furtive glances at her. She did not return them; in fact she seemed indifferent to his presence at the table. When the opportunity arose, Isaac studied her face.

She was even older than he had guessed. Her skin was dark and skeined with wrinkles. Her eyes, bright and liquid, peered out from skully chambers. She held her knife and fork in long, fragile fingers. Her palms were pale. She had changed out of her desert garb into clothing more like what the other adults wore: jeans and a pale yellow cotton shirt. Her hair was thin and cut close to the scalp. She wore no rings or necklaces. In the crook of one elbow was a patch of cotton held down with surgical tape: Mrs. Rebka, the community physician, must already have taken a blood sample from her. But that happened to every newcomer. Isaac wondered if Mrs. Rebka had had a hard time finding a vein in that small sinewy arm. He wondered what the blood test had been meant to detect, and whether Mrs. Rebka had found what she was looking for.

No special attention was paid to the newcomer at dinner. She joined in conversation but the talk remained superficial, as if no one wanted to give away any secrets before the stranger was fully approved, absorbed, understood. It was not until the dishes had been cleared and several pots of coffee placed on the long table that Dr. Dvali introduced Isaac to her.

"Isaac," he began, and the boy gazed at the tabletop uncomfortably, "this is Sulean Moi—she's come a long way to meet you."

A long way? What did that mean? And—to meet him?

"Hello, Isaac," the newcomer said. Her voice was not the harsh croak he had expected. In fact her voice was mellifluous despite a certain grit… and, in some way he could not pin down, familiar.

"Hello," he said, still avoiding her eyes.

"Please call me Sulean," she said.

He nodded cautiously.

"I hope we'll be friends," she said.

He did not, of course, tell her immediately about his newfound ability to distinguish the points of the compass with his eyes closed. He hadn't told anyone about that, not even stern Dr. Dvali or the more sympathetic Mrs. Rebka. He was afraid of the scrutiny it would bring.

Sulean Moi, who moved into the compound, made a point of visiting him every morning after classes and before lunch. At first Isaac dreaded these visits. He was shy and not a little frightened of Sulean's great age and apparent frailty. But she was steadily, courteously friendly. She respected his silences, and the questions she asked were seldom awkward or intrusive.

"Do you like your room?" she asked one day.

Because he preferred to be alone he had been given this room to himself, a small but uncluttered chamber on the second story of the easternmost wing of the largest house. There was a window overlooking the desert, and Isaac had put his desk and chair in front of that window, his bed against the farther wall. He liked to keep the shutters open at night, to let the dry wind touch the bedsheets, his skin. He liked the smell of the desert.

"I grew up in a desert," Sulean told him. A slant of sunlight through the window illuminated her left side, one arm and the parchment of her cheek and ear. Her voice was almost a whisper.

"This desert?"

"No, not this one. But one not very different."

"Why did you leave?"

She smiled. "I had places to go. Or at least I thought I did."

"And this is where you came?"

"Ultimately. Yes."

Because he liked her, and because he could not help being aware of what was unspoken between them, Isaac said, "I don't have anything to give you."

"I don't expect anything," she said.

"The others do."

"Do they?"

"Dr. Dvali and the rest. They used to ask me a lot of questions—how I felt, and what ideas I had, and what things in books meant. But they didn't like my answers." Eventually they had stopped asking, just as they had stopped giving him blood tests, psychological tests, perception tests.

"I'm perfectly satisfied with you the way you are," the old woman said.

He wanted to believe her. But she was new, she had walked through the desert with the nonchalance of an insect on a sunny rock, her purposes were vague, and Isaac was still reluctant to share his most troublesome secrets.

All the adults were his teachers, though some were more patient or attentive than others. Mrs. Rebka taught him basic biology, Ms. Fischer taught him the geography of Earth and the New World, Mr. Nowotny told him about the sky and the stars and the relationship of suns and planets. Dr. Dvali taught him physics: inclined planes, the inverse square, electromagnetism. Isaac remembered his astonishment the first time he saw a magnet lift a spoon from a tabletop. An entire planet pulling downward, and what was this bit of stone in its power to reverse that universal flow? He had only begun to make sense of Dr. Dvali's answers.

Last year Dr. Dvali had shown him a compass. The planet, too, was a magnet, Dr. Dvali said. It had a rotating iron core, hence lines of force, a shield against charged particles arriving from the sun, a polarity that distinguished north from south. Isaac had asked to borrow the compass, a hefty military model made on Earth, and Dr. Dvali had generously allowed him to keep it.

Late in the evening, alone in his room, Isaac placed the compass on his desk so that the red point of the needle aligned with the letter N. Then he closed his eyes and spun himself around, stopped and waited for his dizziness to subside. Eyes still closed, he felt what the world told him, intuited his place in it, found the direction that eased some inner tension. Then he put out his right hand and opened his eyes to see which way he was pointing. He found out a lot of things, mostly irrelevant.

He performed the experiment on three successive nights. Each night he discovered himself aligned almost perfectly with the W on the face of the compass.

Then he did it again. And again. And again.

It was shortly before the annual meteor shower that he resolved at last to share this unsettling discovery with Sulean Moi.

The meteor shower came at the end of every August—this year, on the 34th . (Months in the New World were named after terrestrial months, though each one lasted a few days longer than its namesake.) On the eastern coast of Equatoria, August signalled the beginning of the end of the mild summer: boats left the rich northern fisheries with their last harvests in order to arrive back at Port Magellan before the autumn storms began. Here in the desert it signified little more than the steady, subtle cooling of the nights. Desert seasons were nocturnal, it seemed to Isaac: the days were mostly alike, but winter nights could be bitingly, painfully cold.

Slowly Isaac had allowed Sulean Moi to become his friend. It wasn't that they talked much or about anything especially important. Sulean seemed almost as wordless as Isaac often was. But she accompanied him on his walks through the hills, and she was more agile than seemed possible for her age: she was slow, but she could climb as well as Isaac, and she could sit motionless for an hour or more when Isaac did. She never gave him the impression that this was a duty or a strategy or anything more or less than her way of sharing certain pleasures he had always suspected were his alone.

Sulean must not have seen the annual meteor shower before, since she told Isaac she had arrived in Equatoria only months ago. Isaac was a fan of the event and declared that she ought to see it from a good vantage point. So—with the uneasy permission of Dr. Dvali, who didn't seem to entirely approve of Sulean Moi—on the evening of the 34th he escorted her to the flat rock in the hills, the rock from which he had first seen her appear on the sun-quivering horizon.

That had been daylight, but now it was dark. The New Worlds moon was smaller and faster than Earth's, and it had traversed the sky completely by the time Sulean and Isaac arrived at their destination. Both carried hand lanterns to light their way, and both wore high boots and thick leggings to protect them from the sandfish that often basked on these granite ledges while the stone was still breathing out the heat of the day. Isaac scanned the location carefully and found no wildlife present. He sat crosslegged on the stone. Sulean bent slowly but without complaint into the same posture. Her face was serene, calmly expectant. They turned off their lanterns and allowed the darkness to swallow them up. The desert was blacker than the sky, the sky was salted with stars. No one had officially named these stars, though astronomers had given them catalog numbers. The stars were as dense in the heavens as swarming insects. Each star was a sun, Isaac knew, and many of them cast their light on inaccessible, unknowable landscapes—perhaps on deserts like this one. Things lived among the stars, he knew. Things that lived vast slow cold lives, in which the passage of a century was no more than the blink of a distant eye.

"I know why you came here," Isaac said.

He couldn't see the old woman's face in this darkness, which made the conversation easier, eased the embarrassing clumsiness of words like bricks in his mouth.

"Do you?"

"To study me."

"No. Not to study you, Isaac. I'm more a student of the sky than I am of you in particular."

Like the others at the compound, she was interested in the Hypothetical—the unseen beings who had rearranged the heavens and the earth.

"You came because of what I am."

She cocked her head and said, "Well, yes, that."

He began to tell her about his sense of direction. He spoke haltingly at first, and more confidently when she listened without questioning him. He tried to anticipate the questions she might want to ask. When had he first noticed this special talent? He couldn't remember; only that it had been this year, a few months ago, just a glimmering at first: for instance, he had liked to work in the compound's library because his desk there faced the same direction as the desk in his room, though there was no window to look through. In the dining room he always sat at the side of the table nearest the door, even when there was no one else present. He had moved his bed so that he could sleep more comfortably, aligned with—with, well, what?

But he couldn't say. Everywhere he went, always, when he stood still, there was a direction he preferred to face. This was not a compulsion, only a gentle urge, easily ignored. There was a good way to face, and a less good way to face.

"And are you facing the good way now?" Sulean asked.

In fact he was. He hadn't been aware of it before she asked, but he was comfortable on this rock looking away from the mountains into the lightless hinterland.

"West," Sulean said. "You like to face west."

"A little north of west."

There. The secret was out. There was nothing more to say, and he heard Sulean Moi adjust her posture in the silence, adapting to the pressure of the rock. He wondered if it was painful or uncomfortable to be so old and to sit on solid stone. If so, she gave no indication of it. She looked up at the sky.

"You were right about the falling stars," she said after a long time. "They're quite lovely."

The meteor shower had begun.

Isaac was fascinated by it. Dr. Dvali had told him about meteors, which were not really stars at all but burning fragments of rock or dust, the remains of ancient comets circling for millennia around the New World's sun. But that explanation had only added to Isaac's fascination. He sensed in these evanescent lights the enacting of ancient geometries, vectors set in motion long before the planet was formed (or before it had been constructed by the Hypotheticals), rhythms elaborated over a lifetime or several lifetimes or even the lifetime of a species. Sparks flew across the zenith, east to west, while Isaac listened inwardly to the murmurings of the night.

He was content that way, until Sulean suddenly stood and peered back toward the mountains and said, "Look—what's that? It looks like something falling."

Like luminous rainfall, as if a storm had come down through the high passes of the divide—as they sometimes did, but this glow wasn't lightning; it was diffuse, persistent. She said, "Is that normal?"

"No," Isaac said.

No. It wasn't normal at all.

"Then perhaps we ought to go back."

Isaac nodded uneasily. He wasn't afraid of the approaching—well, "storm," if that's what it was—but it carried a significance he couldn't explain to Sulean, a relationship to the silent presence that lived under the Rub al-Khali, the Empty Quarter of the far west, and to which his private compass was attuned. They walked back to the compound at a brisk pace, not quite running, because Isaac wasn't sure that someone as fragile-seeming as Sulean could run, while the mountain peaks to the east were first revealed and then obscured by fresh waves of this peculiar cloudy light. By the time they reached the gate the meteor shower was entirely hidden by this new phenomenon; a sort of dust had begun to fall from the sky and Isaac's lantern carved out an increasingly smaller swath of visibility. Isaac thought this falling substance might be snow—he had seen snow in videos—but Sulean said no, it wasn't snow at all, it was more like ash. The smell of it was rank, sulfurous.

Like dead stars, Isaac thought, falling.

Mrs. Rebka was waiting at the compound's main door and she pulled Isaac inside with a grip so intense it was painful. He gave her a shocked, reproving look: Mrs. Rebka had never hurt him before; none of the adults had hurt him. She ignored his expression and held him possessively, told him she had been afraid he would be lost in this, this…

Words failed her.

In the common room, Dr. Dvali was listening to an audio feed from Port Magellan, the great city on the eastern coast of Equatoria. The signal was relayed across the mountains by aerostats and was intermittent, Dr. Dvali told the gathered adults, but he had learned that the Port was experiencing the same phenomenon, a blanketing fall of something like ash, and that there was no immediate explanation. Some people in the city had begun to panic. Then the broadcast, or the aerostat relaying the signal, failed entirely.

Isaac, at Mrs. Rebka's urging, went to his room while the adults talked. He didn't sleep, couldn't imagine sleeping. Instead he sat at the window, where there was nothing to see but a tunneled grayness where the overhead light bled into the ashfall, and he listened to the sound of nothing at all—a silence that nevertheless seemed to speak to him, a silence steeped in meaning.

CHAPTER TWO

Lise Adams drove toward the little rural airstrip on the afternoon of the 34th of August feeling lost, feeling free. It was a feeling she couldn't explain even to herself. Maybe the weather, she thought. Late August along the coast of Equatoria was inevitably warm, often unbearable, but today the breeze from the sea was gentle and the sky was that indigo blue she had come to associate with the New World, deeper and truer than the smudgy pastel skies of Earth. But the weather had been fine for weeks, nice but not all that remarkable. Free, she thought, yes, absolutely: a marriage behind her, the decree nisi freshly-issued, an unwise thing undone… and, ahead of her, the man who had been a factor in that undoing. But so much more than that. A future severed from her past, a painful question hovering on the brink of an answer.

And lost, almost literally: she had only come out this way a couple of times before. South of Port Magellan, where she had rented an apartment, the coast flattened into an alluvial plain that had been given over to farms and light industry. Much of it was still wild, a sort of rolling prairie grown over with feathery grasses, meadows that broke like waves against the peaks of the coastal range. Before long she began to see small aircraft coming and going from Arundji's Airfield, which was her destination. These were little prop planes, bush planes: the runways at Arundji's weren't long enough for anything big. The planes that alighted there were either rich men's hobbies or poor men's businesses. If you wanted to rent a hangar, join a tourist excursion into the glacial passes, or get to Bone Creek or Kubelick's Grave in a hurry, you came to Arundji's. And if you were smart you talked to Turk Findley, who flew discount charters for a living, before you did any of those things.

Lise had flown with Turk once before. But she wasn't here to hire a pilot. Turk's name had come up in connection with the photograph Lise carried in a brown envelope, currently tucked into the glove compartment of her car.

She parked in the gravel lot at Arundji's, climbed out of the car, and stood listening to the sound of insects buzzing in the afternoon heat. Then she walked through the door at the back of the cavernous tin-roofed shed—it looked like a converted cow barn—that served as Arundji's passenger terminal. Turk's charter business operated out of a corner of this building with the consent of Mike Arundji, the airfield's owner, who took a share of Turk's profits in return. Turk had told her this, back when they had had time to talk.

There was no security barrier to pass through. Turk Findley worked out of a three-sided cubicle tucked into the north end of the building, and she simply walked into it and cleared her throat in lieu of knocking. He was behind his desk filling out what looked like UN Provisional Government papers—she could see the blue logo at the top of the page. He inked his signature a final time and looked up. "Lise!"

His grin was genuine and disarming. No recrimination, no why-didn't-you-return-my-calls. She said, "Uh, are you busy?"

"Do I look busy?"

"Looks like you have work to do, anyhow." She was fairly certain he would be willing to put aside anything nonessential for a chance to see her: a chance she hadn't offered him in a long time. He came around the desk and hugged her, chastely but sincerely. She was briefly flustered by the smell of him in close proximity. Turk was thirty-five years old, eight years older than Lise, and a foot taller. She tried not to let that be intimidating. "Paperwork," he said. "Give me an excuse to ignore it. Please."

"Well," she said.

"At least tell me if it's business or pleasure."

"Business."

He nodded. "Okay. Sure. Name a destination."

"No, I mean—my business, not your business. There's something I'd like to talk to you about, if you're willing. Maybe over dinner? My treat?"

"I'd be happy to go to dinner, but it's on me. I can't imagine how I can help you write your book."

She was pleased that he remembered what she had told him about her book. Even though there was no book. An aircraft taxied up to a hangar some yards away and the noise came through the thin walls of Turk's office as if through an open door. Lise looked at the ceramic cup on Turk's desk and saw the oily surface of what must have been hours-old coffee break into concentric ripples. When the roar faded she said, "Actually you can help a lot, especially if we can go somewhere quieter…"

"Sure thing. I'll leave my keys with Paul."

"Just like that?" She never ceased to marvel at the way people on the frontier did business. "You're not afraid of missing a customer?"

"Customer can leave a message. I'll get back sooner or later. Anyhow, it's been slow this week. You came at the right time. What do you say to Harley's?"

Harley's was one of the more upscale American-style restaurants in the Port. "You can't afford Harley's."

"Business expense. I have a question for you, come to think of it. Call it quid pro quo."

Whatever that meant. All she could say was, "Okay." Dinner at Harley's was both more and less than she had expected. She had driven out to Arundjis on the assumption that a personal appearance would be more meaningful than a phone call, after the time that had elapsed since their last conversation. A sort of unspoken apology. But if he resented the gap in their relationship (and it wasn't even a "relationship" anymore, perhaps not even a friendship), he showed no sign of it. She reminded herself to focus on the work. On the real reason she was here. The unexplained loss that had opened a chasm in her life twelve years ago.

Turk had a car of his own at the airfield, so they arranged to meet at the restaurant in three hours, about dusk.

Traffic permitting. Prosperity in Port Magellan had meant more cars, and not just the little South Asian utility vehicles or scooters everyone used to drive. Traffic was thick through the docklands—she was sandwiched between a pair of eighteen-wheelers much of the way—but she made it to the restaurant on time. The parking lot at Harley's was crowded, unusually for a Wednesday night. The food here was reasonably good, but what people paid a premium for was the view: the restaurant occupied a hilltop overlooking Port Magellan. The Port had been established for obvious reasons on what was the largest natural harbor on the coast, close to the Arch that joined this planet to Earth. But its easy lowlands had been overbuilt and the city had expanded up the terraced hillsides. Much of it had been constructed hastily, without reference to whatever building codes the Provisional Government was attempting to enforce. Harley's, all native wood and glass panels, was an exception.

She left her name and waited in the bar for half an hour until Turk's elderly car chugged into the lot. She watched through the window as he locked the vehicle and strode toward the entrance through a deepening dusk. He was clearly not as well-dressed as the average customer at Harley's, but the staff recognized and welcomed him: he often met clients here, Lise knew, and as soon as he joined her, the waiter escorted them to a U-shaped booth with a window view. All the other window tables were occupied. "Popular place," she said.

"Tonight, yeah," he said, and when Lise stared at him blankly he added, "The meteor shower."

Oh. Right. She had forgotten. Lise had been in Port Magellan less than eleven months local time, which meant she had missed last year's meteor shower. She knew it was a big deal, that a kind of informal Mardi Gras had evolved around the occasion, and she remembered the event from the part of her childhood she had spent here—a spectacular celestial display that happened with clockwork regularity, a perfect excuse for a party. But the shower didn't peak until the third night. Tonight was just the beginning.

"But we're at the right place to see it start," Turk said. "In a couple of hours, when it's full dark, they'll turn down the lights and open those big patio doors so everybody gets an unobstructed view."

The sky was a radiant indigo, clear as glacial water, no sign of meteors yet, and the city was arrayed below the restaurant in a gracefully concealing sunset glow. She could see the fires flaring from the refinery stacks in the industrial sector, the silhouettes of mosques and churches, the illuminated billboards along the Rue de Madagascar advertising Hindi movies, herbal toothpaste (in Farsi), and chain hotels. Cruise ships in the harbor began to light up for the night. It was, if you squinted and thought nice thoughts, pretty. She might once have said exotic, but it no longer struck her that way.

She asked Turk how his business was doing.

He shrugged. "I pay the rent. I fly. I meet people. There's not much more to it than that, Lise. I don't have a mission in life."

Unlike you, he seemed to imply. Which led directly to the reason she had gotten in touch with him. She was reaching for her bag when the waiter showed up with ice water. She had barely glanced at the menu, but she ordered paella made with local seafood and seasoned with imported saffron. Turk asked for a steak, medium-well. Until fifteen years ago the most common terrestrial animal on Equatoria had been the water buffalo. Now you could buy fresh beef.

The waiter sauntered away and Turk said, "You could have called, you know."

Since the last time they had been together—since her expedition into the mountains, and a few uneasy arranged meetings afterward—he had phoned her a few times. Lise had returned his calls eagerly at first, then perfunctorily; then, when the guilt set in, not at all. "I know, and I'm sorry, but the last couple of months have been busy for me—"

"I mean today. You didn't have to drive all the way out to Arundji's just to make a date for dinner. You could have called."

"I thought if I called it might be too, you know, impersonal." He said nothing. She added, more honestly, "I guess I wanted to see you first. Make sure things were still okay."

"Different rules out there in the wilderness. I know that, Lise. There are home things and there are away things. I figured we must have been…"

"An away thing?"

"Well, I figured that's how you wanted it."

"There's a difference between what you want and what's practical."

"Tell me about it." He smiled ruefully. "How are things with you and Brian?"

"Over."

"Really?"

"Officially. Finally."

"And that book you're working on?"

"It's the research that's slow, not the writing." She hadn't written a word, never would write a word.

"But it's why you decided to stay."

In the New World, he meant. She nodded.

"And what happens when you're done? You go back to the States?"

"Possibly."

"It's funny," he said. "People come to the Port for all kinds of reasons. Some of them find reasons to stay, some don't. I think people just cross a certain line. You get off the boat for the first time and you realize you're literally on another planet—the air smells different, the water tastes different, the moon's the wrong size and it rises too fast. The day's still divided into twelve hours but the hours run long. After a few weeks or a few months people get disoriented on some deep level. So they turn around and go home. Or else it snaps into place and starts to feel normal. That's when they have second thoughts about going back to the anthill cities and bad air and septic oceans and all that stuff they used to take for granted."

"Is that why you're here?"

"In part, I guess," he said. "Sure."

Their meals arrived, and they ate and talked about nothing in particular for a while. The sky darkened, the city glittered, the waiter came back to clear the table. Turk ordered coffee. Lise summoned her courage and said, "Will you look at a photograph for me? Before they dim the lights."

"Sure. What kind of photograph?"

"A picture of someone who might have chartered a flight with you. This would have been a few months ago."

"You've been looking at my passenger manifests?"

"No! I mean, not me… you file manifests with the PG, right?"

"What's this about, Lise?"

"There's a lot I can't explain right now. Will you look at the picture first?"

He was frowning. "Show me."

Lise took her bag into her lap and withdrew the envelope. "But you said you had a favor to ask, too—"

"You first."

She passed the envelope across the linen tablecloth. He pulled out the picture. His expression didn't change. Finally he said, "I assume there's a story goes with this?"

"It was taken by a security camera at the docks late last year. The image has been enlarged and enhanced."

"You have access to security camera downloads, too?"

"No, but—"

"So you got these from someone else. One of your friends at the consulate. Brian, or one of his buddies."

"I can't go into that."

"Can you at least tell me why you're curious about—" He gestured at the image. "An old lady?"

"You know I've been trying to interview people who were connected with my father. She's one of them. Ideally, I'd like to make contact with her."

"Any particular reason? I mean, why this woman?"

"Well… I can't go into that."

"The conclusion I'm drawing here is that all roads lead back to Brian. What's his interest in this woman?"

"Brian works for the Department of Genomic Security. I don't."

"But someone there is doing you favors."

"Turk, I—"

"No, never mind. Don't ask, don't tell, right? Obviously, somebody knows I flew with this person. Which means somebody besides yourself would like to find her."

"That's a reasonable inference. But I'm not asking you on behalf of anyone else. What you choose to say or not say to anyone at the consulate is your own business. What you say to me stays with me."

He looked at her as if he were evaluating this statement. But, Lise thought, why should he trust her? What had she ever done to instill trust in him, besides sleep with him during the course of one exceptional weekend?

"Yeah," he said finally, "I flew with her."

"Okay… can you tell me anything about her? Where she is, what she talked about?"

He sat back in his chair. True to his prediction, the lights in the restaurant began to dim. A couple of waiters rolled back the glass wall that separated the indoor dining room from the patio. The sky was starry and deep, slightly washed out by the lights of the Port but still crisper than any sky Lise had known back in California. Had the meteor shower begun? She saw what looked like a few bright flashes across the meridian.

Turk hadn't spared it a glance. "I'll have to think about this."

"I'm not asking you to violate any confidences. Just—"

"I know what you're asking. And it's probably not unreasonable. But I'd like to think it over, if that's okay with you."

"All right." She couldn't push it any farther. "But you mentioned a quid pro quo?"

"Just something I'm curious about—I thought you might have picked up a word or two from one of those sources you don't like to discuss. Arundji got a memo this morning from the air regs department of the Provisional Government. I filed a flight plan for the far west, and all else being equal I probably would have been in the air by the time you drove up this afternoon. But they disallowed the flight. So I called around to find out what's happening. Seems like nobody's being allowed to fly into the Rub al-Khali."

"How come?"

"They won't say"

"This flight ban, is it temporary?"

"Also a question I can't get an answer to."

"Who imposed it? Under what authorization?"

"Nobody at the PG will own up to anything. I've been shuffled between a dozen departments and so has every other pilot who's affected by this. I'm not saying there's anything sinister about it, but it's kinda surprising. Why turn the western half of the continent into a no-fly zone? There are still regular flights to and from the oil allotments, and past that there's nothing but rocks and sand. Hikers and wilderness types go there—that's who had my charter. I don't understand it."

Lise desperately wished she had a factoid or two to barter with, but this was the first she'd heard of the flight ban. It was true she had contacts at the U.S. Consulate, her ex-husband chief among them. But the Americans were only advisory members of the Provisional Government. And Brian wasn't even a diplomat, just a DGS functionary.

"All I can do is ask," she said.

"Appreciate it if you would. So. Business attended to? At least for now?"

"For now," she said reluctantly.

"Then what do you say we take our coffee out on the patio while we can still find a table?"

Three months ago she had hired Turk to fly her across the Mohindar Range to a pipeline outpost called Kubelick's Grave. Strictly a business arrangement. She had been trying to track down an old colleague of her father's, a man named Dvali, but she never reached Kubelick's Grave: a squall had forced the plane down in one of the high mountain passes. Turk had landed his aircraft on a nameless lake while clouds like cannon smoke billowed between granite peaks north and south of them. He had moored the plane on a pebbly beach and set up a surprisingly comfortable camp under a stand of trees that looked to Lise like bulbous, mutant pines. The wind had whistled down that pass for three days while visibility declined to nothing. Set foot outside the canvas tent and you'd be lost within a couple of meters. But Turk was a passable woodsman and had packed for emergencies, and even canned food was delicious when you were barricaded against nature and equipped with a camp stove and a hurricane lantern. Under other circumstances it might have been a three-day endurance contest, but Turk turned out to be good company. She had not meant to seduce him and she believed he had not set out to seduce her. The attraction had been sudden and mutual and utterly explicable.

They had exchanged stories and warmed each other when the wind turned cold. At the time it had seemed to Lise that she would be happy to wrap Turk Findley around herself like a blanket and shut out the rest of the world forever. And if you had asked her whether she was on the verge of something more meaningful than an unexpected tryst, she might have said yes, maybe.

She had meant to keep up the relationship when they arrived back in the Port. But the Port had a way of subverting your best intentions. Problems that had seemed featherweight from the inside of a tent in the Mohindar Range regained their customary mass and inertia. Her separation from Brian was an established fact by that time, at least in her mind, though Brian was still liable to spasms of let's-work-it-out, well meant, she supposed, but humiliating for both of them.

She had told him about Turk, and while that stonewalled Brian's attempts at reconciliation it introduced a whole new vector of guilt: she began to suspect herself of using Turk as a lever—a sort of emotional crowbar against Brian's attempts to rekindle a dead fire. So, after a few uneasy meetings, she had let the relationship lapse. Better not to complicate what was already a complicated situation.

But now there was a decree nisi in the glove compartment of her car: her future was a blank page, and she was tempted to write on it.

The crowd on the patio began to react to the meteor shower. She looked up as three scaldingly-bright white lines scribed across the meridian. The meteors emanated from a point well above the horizon and almost directly due east, and before she could look away there were more of them—two, then one, then a spectacular cluster of five.

She was reminded of a summer in Idaho when she had gone stargazing with her father—she couldn't have been more than ten years old. Her father had grown up before the Spin and he had talked to her about the stars "the way they used to be," before the Hypotheticals dragged the Earth a few billion years down the river of time. He missed the old constellations, he said, the old star names. But there had been meteors that night, dozens of them, the largest intercepted by the invisible barrier that protected the Earth from the swollen sun, the smallest incinerated in the atmosphere. She had watched them arc across the heavens with a speed and brilliance that left her breathless.

As now. The fireworks of God. "Wow," she said, lamely.

Turk pulled his chair around to her side of the table so they were both facing the sea. He didn't make any kind of an overt move and she guessed he probably wouldn't. Navigating the high mountain passes must have been simple compared to this. She didn't make any moves either, was careful not to, but she couldn't help feeling the heat of his body inches from hers. She sipped her coffee without tasting it. There was another flurry of falling stars. She wondered aloud whether any of them ever reached the ground.

"It's just dust," Turk said, "or that's what the astronomers say. What's left of some old comet."

But something new had caught her attention. "So what about that?" she asked, pointing east, lower on the horizon, where the dark sky met the darker sea. It looked to Lise like something was actually falling out there—not meteors but bright dots that hung in the air like flares, or what she imagined flares would look like. The reflected light of them colored the ocean a streaky orange. She didn't remember anything like that from her previous time in Equatoria. "Is that part of it?"

Turk stood up. So did a few others among the crowd on the patio. A puzzled hush displaced the talk and laughter. Here and there, phones began to buzz or chatter.

"No," Turk said. "That's not part of it."

CHAPTER THREE

It was like nothing Turk had seen during his ten years in the New World.

But, in a way, that was exactly typical. The New World had a habit of reminding you it wasn't Earth. Things happened differently here. It ain't Kansas, as people liked to say, and they probably said the same thing in a dozen different languages. It ain't the Steppes. It ain't Kandahar. It ain't Mombassa.

"Do you think it's dangerous?" Lise asked.

Some of the restaurant's clientele evidently thought so. They settled their bills with barely-disguised haste and made for their cars. Within a few minutes there were only a few stalwarts left on the broad wooden patio. "You want to leave?" Turk asked.

"Not if you don't."

"I guess we're as safe here as anywhere," Turk said. "And the view is better."

The phenomenon was still hanging out at sea, though it seemed to move steadily closer. What it looked like was luminous rain, a rolling gray cloud shot with light—the way a thunderstorm looked when you saw it from a long way off, except that the glow wasn't fitful, like lightning, but seemed to hang below the billowing darkness and illuminate it from beneath. Turk had seen storms roll in from sea often enough, and he estimated that this one was approaching at roughly the local wind speed. The brightness falling from it appeared to be composed of discrete luminous or burning particles, maybe as dense as snow, but he could be wrong about that—it didn't snow in this part of Equatoria and the last snow he had seen was off the coast of Maine many years back.

His first concern was fire. Port Magellan was a tinderbox, crowded with sub-code housing and shacks; the docklands housed countless storage and transport facilities and the bay was thick with oil and LNG tankers, funneling fuel to the insatiable Earth. What looked like a dense squall of lit matches was blowing in from the east, and he didn't want to think about the potential consequences of that.

He said nothing to Lise. He imagined she had drawn many of the same conclusions, but she didn't suggest running—was smart enough, he guessed, to know there was no logical place to run to, not at the speed this thing was coming. But she tensed up as the phenomenon visibly approached the point of land at the southern extremity of the bay.

"It's not bright all the way down," she said.

The staff at Harley's started dragging in tables from the patio, as if that was going to protect anything from anything, and urged the remaining diners to stay indoors until someone had some idea what was going on. But the waiters knew Turk well enough to let him alone. So he stayed out a while longer with Lise and they watched the light of the flares, or whatever they were, dancing on the distant sea.

Not bright all the way down. He saw what she meant. The shifting, glittering curtains tailed into darkness well before they reached the surface of the ocean. Burned out, maybe. That was a hopeful sign. Lise took out her phone and punched up a local news broadcast, relaying bits of it to Turk. They were talking about a "storm," she said, or what looked on radar like a storm, the fringes of it extending north and south for hundreds of miles, the heart of it more or less centered on the Port.

And now the bright rain fell over the headlands and the inner harbor, illuminating the decks and superstructures of cruise ships and cargo vessels at anchor. Then the silhouettes of the cargo cranes grew misty and obscure, the tall hotels in the city dimmed in the distance, the souks and markets vanished as the shining rain moved up the hillsides and seemed to grow taller as it came, a canyon wall of murky light. But nothing burst into flame. That was good, Turk thought. Then he thought: but it could be toxic. It could be any fucking thing. "About time to move indoors," he said.

Tyrell, the headwaiter at Harley's, was a guy Turk had briefly worked with on the pipelines out in the Rub al-Khali. They weren't big buddies or anything but they were friendly, and Tyrell looked relieved when Turk and Lise finally abandoned the patio. Tyrell slid the glass doors shut and said, "You got any idea—?"

"No," Turk said.

"I don't know whether to run or just enjoy the show. I called my wife. We live down in the Flats." A low-rent neighborhood some few miles along the coast. "She says it's happening there, too. She says there's stuff falling on the house, it looks like ash."

"But nothing's burning?"

"She said not."

"It could be volcanic ash," Lise said, and Turk had to admire how she was handling all this. She was tense but not visibly afraid, not too scared to venture a theory. "It would have to have been some kind of tectonic event way out over the horizon, something at sea…"

"Like a sea volcano," Tyrell said, nodding.

"But we would have felt something before the ash got to us if it was anywhere close—an earthquake, a tsunami."

"Been no report of any such thing," Turk said, "far as I know."

"Ash," Tyrell added. "Like, gray and powdery."

Turk asked Tyrell if there was any coffee back in the kitchen and Tyrell said yeah, not a bad idea, and went to check. There were still a few diners in the restaurant, people with nowhere better to go, though nobody was eating or celebrating. They sat at the innermost tables and talked nervously with the waitstaff.

The coffee came and it was good and dense, and Turk added cream to his cup just as if the sky weren't falling. Lise's phone buzzed repeatedly, and she fended off a couple of friendly calls before shunting everything to her voice mail. Turk didn't get any calls, though his phone was in his shirt pocket.

Now the ash began to fall on Harley's patio, and Turk and Lise moved closer to the window to watch.

Gray and powdery. Tyrell's description was on the money. Turk had never seen volcanic ash, but he imagined this was what it might look like. It sifted down over the wooden slats and boards of the patio and drifted against the window glass. It was like snow the color of an old wool suit, but here and there were flecks of something shiny, something still luminous, which dimmed as he watched.

Lise pressed up against his shoulder, wide-eyed. He thought again of their weekend up in the Mohindar Range, marooned by weather on that nameless lake. She had been just as self-possessed back then, just as balanced, braced for whatever the situation might throw at her. "At least," he said, "nothing's burning."

"No. But you can smell it."

He could, now that she mentioned it—a mineral smell, slightly acrid, a little sulfuric.

Tyrell said, "You think it's dangerous?"

"Nothing we can do about it if it is."

"Except stay indoors," Lise said. But Turk doubted that was practical. Even now, through the glittering ashfall, he could make out traffic on Rue Madagascar, pedestrians scurrying down the sidewalks covering their heads with jackets or handkerchiefs or newspapers. "Unless—"

"Unless what?"

"Unless," she said, "this goes on too long. There's not a roof in Port Magellan built to bear much weight."

"And it isn't just dust," Tyrell said.

"What?"

"Well, look.'" He gestured at the window.

Absurdly, impossibly, something the shape of a starfish drifted past the glass. It was gray but speckled with light. It must have weighed nearly nothing because it floated in the weak breeze like a balloon, and when it reached the deck of the patio it crumbled into powder and a few larger fragments.

Turk gave Lise a glance. She shrugged, incredulous.

"Get me a tablecloth," Turk said.

Tyrell said, "What do you want with a tablecloth?"

"And one of those linen napkins."

"You don't want to mess with the linen," Tyrell said. "Management's very strict about that."

"Go get the manager, then."

"Mr. Darnell's off tonight. I guess that makes me the manager."

"Then get a tablecloth, Tyrell. I want to check this out."

"Don't mess up my place."

"I'll be careful."

Tyrell went to undress a table. Lise said, "You're going out there?"

"Just long enough to retrieve a little of whatever's coming down."

"What if it's toxic?"

"Then I guess we're all fucked." She flinched, and he added, "But we'd probably know by now if it was."

"Can't be good for your lungs, whatever it is."

"So help me tie that napkin over my face."

The remaining diners and waiters watched curiously but made no effort to help. Turk took the tablecloth to the nearest exit to the patio and gestured to Tyrell to slide open the glass door. The smell immediately intensified—it was something like wet, singed animal hair—and Turk hurriedly spread the tablecloth on the patio floor and backed inside.

"Now what?" Tyrell said.

"Now we let it sit a few minutes."

He rejoined Lise, and, bereft of conversation, they watched the dust come down for a quarter of an hour more. Lise asked him how he planned to get home. He shrugged. He lived in what was essentially a trailer a few miles downcoast from the airfield. There was already a good half inch of ash on the ground and traffic was crawling.

"I'm only a couple of blocks from here," she said. "The new building on Rue Abbas by the Territorial Authority compound? It ought to be fairly sturdy."

It was the first time she had invited him home. He nodded.

But he was still curious. He waved down Tyrell, who had been serving coffee to everyone still present, and Tyrell slid open the patio door one more time. Turk gripped the open tablecloth, now burdened with a layer of ash, and pulled it gently, trying not to disturb whatever fragile structures it might have captured. Tyrell closed the door promptly. "Phew! Stinks."

Turk brushed off the few flakes of gray ash that clung to his shirt and hair. Lise joined him as he squatted to examine the debris-covered tablecloth. A couple of curious diners pulled their chairs a little closer, though they wrinkled their noses at the smell.

Turk said, "You have a pen or a pencil on you?"

Lise rummaged in her purse and came up with a pen. Turk took it from her and used it to probe the layer of dust that had collected on the tablecloth.

"What's that?" Lise asked over his shoulder. "To your left. Looks like, I don't know, an acorn …"

Turk hadn't seen an acorn in years. Oaks didn't grow in Equatoria. The object in the ashfall was about the size of his thumb. It was saucer-shaped at one end and tapered to a blunt point at the other—an acorn, or maybe a tiny egg wearing a minuscule sombrero. It appeared to be made of the same stuff as the fallen ash, and when he touched it with the tip of the pen it dissolved as if it possessed no particular substance at all.

"And over there," Lise said, pointing. Another shaped object, this one resembling a gear out of an old mechanical clock. It, too, crumbled when he touched it.

Tyrell went to the staff room and came back with a flashlight. When he played the beam over the tablecloth at a raking angle it showed up a number of these objects, if you could call them "objects"—the faintly structured remains of things that appeared to have been manufactured. There was a tube about a centimeter long, perfectly smooth; another about the same size, but knobbed like a length of spine from some small animal, a mouse, say. There was a six-pronged thorn; there was a disk with miniature, crumbling spokes, like a bicycle wheel; there was a beveled ring. Some of these things glinted with a faint remnant light.

"All burned," Lise observed.

Burned or otherwise decomposed. But how could something so completely cremated remain even partially intact after falling from the sky? What had these things been made of?

Also present in the ashfall were a few luminous specks. Turk hovered his hand over one of them.

"Careful," Lise said.

"It's not hot. It's not even warm."

"Could be, I don't know, radioactive."

"Could be." If so, it was another doomsday scenario. Everyone outside was inhaling this stuff. Everyone inside soon would be. None of these buildings was airtight, none of them filtered its air.

"You learning anything from this?" Tyrell asked. Turk stood up and brushed his hands.

"Yeah. I'm learning that I know even less than I thought I did."

He accepted Lise's offer of temporary shelter. They borrowed spare kitchen clothing from Tyrell, chef's jackets to protect their clothes from the falling ash, and they shuffled as fast as they could across the gray dunes in the parking lot to Lise's car. The ash cloud had turned the sky dark, obscured the meteor shower, dimmed the streetlights.

Lise drove a Chinese car, smaller than Turk's vehicle but newer and probably more reliable. He shook himself off as he climbed into the shotgun seat.

She steered the vehicle out the back exit from the parking lot onto a narrow but less crowded avenue that connected Rue de Madagascar to Rue Abbas. She maneuvered the car with a kind of cautious grace, nursing it over the accumulations of dust, and Turk let her concentrate on her driving. But as the traffic slowed she said, "You think this is connected with the meteor shower?"

"It seems like more than a coincidence. But who knows."

"This is definitely not volcanic ash."

"Guess not."

"It could have come from outside the atmosphere."

"Could have, I guess."

"So it might be connected to the Hypothetical."

During the Spin, people had speculated endlessly about the Hypothetical, the still-mysterious entities that had bounced the Earth a few billion years into the galactic future and opened a gateway between the Indian Ocean and the New World. Without reaching any reliable conclusions, as far as Turk could tell. "Could be. But that doesn't explain anything."

"My father used to talk about the Hypothetical a lot. One of the things he said was, we tend to forget how much older the universe is now than it was before the Spin. It might have changed in ways we don't understand. Any textbook you pick says comets and meteors are junk falling in from the far edge of the solar system—here, or on Earth, or anywhere in the galaxy. But that was never more than a local observation and it's four billion years out of date. There's a theory that the Hypotheticals aren't biological organisms and never were—"

He waited while she turned a corner, the car's tires fighting for traction. Lise's father had been a college professor. Before he disappeared.

"That they're a system of self-replicating machines living out in the cold parts of the galaxy, at the fringes of planetary systems, with this really slow metabolism that eats ice and generates information…"

"Like those replicators we sent out during the Spin."

"Right. Self-replicating machines. But with billions of years of evolution behind them."

Was this how college profs talked to their daughters? Or was she just talking to ward off panic? "So what are you saying?"

"Maybe whatever falls into the atmosphere this time every year isn't just comet dust. Maybe it's—"

She shrugged.

"Dead Hypothetical," he finished.

"Well, it sounds inane when you put it that way."

"It's as good a theory as any. I don't mean to be skeptical. But we don't have any evidence that whatever's falling out of the sky is from space."

"Cogs and tubes made of ash? Where would it be from?"

"Look at it another way. People have only been on this planet for three decades. We tell ourselves it's all surveyed and reasonably well understood. But that's bullshit. It would be wrong to jump to a conclusion—any conclusion. Even if this is caused by the Hypothetical, that doesn't really explain anything. We've had a meteor shower every summer for thirty years and never anything like this."

The wipers piled dust at the margins of the windshield. Turk saw people on the sidewalks, some of them running, others sheltering in doorways, faces peering anxiously from windows. A Provisional Government police car passed them with its lights and siren on.

"Might be something unusual's happening out where we can't see it."

"Might be the Celestial Dog shaking off fleas. Too soon to say, Lise."

She nodded unhappily and pulled into the parking garage of the building where she lived, a concrete tower that looked as if it had been transplanted from Dade County. In the underground parking shelter there was no evidence of what was going on outside, only a mote or two hanging in the motionless air.

Lise slid her security card through the elevator call slot. "We made it."

So far, Turk thought, yeah.

CHAPTER FOUR

Lise found Turk a robe big enough to decently fit him and told him to put his clothes in the washer, in case the dust clinging to them was in any way toxic. While he did that she took a turn in the shower. When she rinsed her hair, gray water pooled around the drain. An omen, she thought, a portent: maybe the ashfall wouldn't stop until Port Magellan was entombed like Pompeii. She stood under the shower until the water ran clear.

The lights flickered twice before she was done. The electrical grid in Port Magellan was still fairly crude; probably it wouldn't take much to put a local transformer out of commission. She tried to imagine what would happen if this storm (if you could call it that) went on for another day, or two, or more. A whole population trapped in the dark. UN relief ships arriving in the harbor. Soldiers evacuating the survivors. No, better not to imagine it.

She changed into fresh jeans and a cotton shirt, and the lights were still on when she joined Turk in the living room. In her old flannel robe he looked deeply embarrassed but dangerously sexy. Those ridiculously long legs, scarred in places by the life he had led before he started flying passengers over the mountains. He had told her he was a merchant seaman when he arrived here, that his first work in the New World had been on the Saudi-Aramco pipeline. Big blunt hands, well-used.

He gazed around in a way that made her conscious of her apartment, the wide east-facing window, the video panel and her small library of books and recordings. She wondered how it seemed to him. A little upscale, probably, compared to what he called "his trailer," a little too back-home, too obviously an imported fragment of North America, though it was still new to her, still slightly uninhabited—the place she had brought her stuff after she split from Brian.

Not that he showed any sign of such thoughts. He was watching the local news channel. There were three daily papers in Port Magellan but only one news channel, overseen by a bland and complexly multicultural board of advisors. It broadcast in fifteen languages and was, as a rule, interesting in none of them. But now there was something substantial to talk about. A camera crew had gone out in the ashfall to get views from street level, while two commentators read advisories from various departments of the Provisional Government.

"Turn it up," Lise said.

The big intersection at Portugal and Tenth was shut down, stranding a busful of tourists desperate to get back to their cruise ship. Radio transmission had been compromised by the gunk in the atmosphere and communication with vessels at sea was intermittent. A government lab was doing hasty chemical analysis of the fallen ash, but no results had been announced. Some respiratory problems had been reported but nothing to suggest that the ash was immediately harmful to human health. Loose talk suggested a link between the ashfall and the annual meteor shower, but that was impossible to confirm. Best advice from local authorities was to hunker down, keep doors and windows closed, wait it out.

Everything after that was more of the same. Lise didn't need a reporter to tell her the city was shutting down. The usual night noises had gone silent, apart from the periodic wail of emergency-vehicle sirens.

Turk muted the display and said, "My clothes are probably clean by now." He walked to the laundry alcove and took his T-shirt and jeans into the bathroom to dress. He had been more brazen out in the lake country. But then, so had she. Lise made up the sofa as a bed for him. Then she said, "How about a nightcap?"

He nodded.

In the kitchen she drained what was left of her last bottle of white wine into two glasses. When she came back to the living room Turk had opened the blinds and was peering out into the darkness. A deepening wind swept falling ash past the window. She could smell it, faintly. That sulfurous reek.

"Reminds me of diatoms," Turk said, accepting a glass.

"Excuse me?"

"You know. Out in the ocean there's plankton? Microscopic animals? They grow a shell. Then the plankton dies and the shells drift down through the sea and make a kind of silt, and if you dredge it up and look at it under a microscope you see all these plankton skeletons—diatoms, little stars and spikes and so forth."

Lise watched the ash drift and thought about Turk's analogy. The remains of things once living settling through the turbulent atmosphere. The shells of dead Hypotheticals.

It would not have surprised her father, she thought.

She was still contemplating that when her phone buzzed again. This time she picked up: she couldn't exclude the exterior world forever—she'd have to reassure friends that she was all right. She briefly and guiltily hoped that it wouldn't be Brian on the other end; but, of course, it was.

"Lise?" he said. "I was worried sick about you. Where are you?"

She walked to the kitchen as if to put some symbolic space between Brian and Turk. "I'm fine," she said. "I'm home."

"Well, good. Lot of people aren't."

"How about you?"

"I'm in the consulate compound. There's a lot of us here. We thought we'd stick it out, sleep on cots. The building has a generator if the power goes down. You have power?"

"At the moment."

"About half the Chinese district is in the dark. The city's having trouble getting repair crews out."

"Anybody there know what's going on?"

Brian's voice came through the phone with a stressed reediness, the way he sounded when he was nervous or upset. "No, not really…"

"Or when it's going to stop?"

"No. It can't go on forever, though."

That was a nice thought, but Lise doubted she could convince herself of the truth of it, at least not tonight. "Okay, Brian. Appreciate the call but I'm fine."

There was a pause. He wanted to say more. Which was what he always seemed to want these days. A conversation, if not a marriage.

"Let me know if you have a problem there."

She thanked him and cut the connection, left the phone on the kitchen counter and walked back into the living room.

"Was that your ex?" Turk asked.

Turk knew about her problems with Brian. In the mountains, by the side of a stormy lake, she had shared a number of difficult truths about herself and her life. She nodded.

"Am I creating a problem for you here?"

"No," she said. "No problem."

She sat up with Turk watching more sporadic news, but fatigue caught up with her around three in the morning and she finally staggered off to bed. Even so she was awake for a while in the dark, curled under a cotton sheet as if it could protect her from whatever was falling out of the sky. It isn't doomsday, she told herself. It's just something inconvenient and unexpected.

Diatoms, she thought: sea shells, ancient life, another reminder that the universe had shifted radically during and after the Spin, that the kind of world she had been born into was not the world her parents or her grandparents had ever expected to see. She remembered an old astronomy book of her grandfather's that had fascinated her as a child. The last chapter was called Are We Alone? and it had been full of what seemed like naive, silly speculation. Because that question had been answered. No, we are not alone. No, we can never again think of the universe as our private property. Life, or something like life, had been here long before the evolution of human beings. We're on their turf, Lise thought, and because we don't understand them we can't predict their behavior. Even today no one knew with any certainty why the Earth had been preserved down four billion years of galactic history like a tulip bulb wintering in a dark cellar, or why a seaway to this new planet had been installed in the Indian Ocean. What was falling outside the window was just more evidence of humanity's gross ignorance.

She slept longer than she meant to and woke with daylight in her eyes—not sunlight, exactly, but a welcome ambient brightness. By the time she dressed, Turk was already awake. She found him at the living room window, gazing out.

"Looks a little better," she said.

"At least, not as bad."

There was still a flat, glittery dust in the outside air. But it wasn't falling as thickly as it had last night and the sky was relatively clear.

"According to the news," Turk said, "the precipitation—that's what they're calling it—is tapering off. The ash cloud is still there but it's moving inland. What they can see on radar and satellite images suggests the whole thing might be finished late tonight, early tomorrow, at least as far as the coast is concerned."

"Good," Lise said.

"But that's not the end of the problem. The streets need to be cleared. There's still trouble with the electrical grid. A few roofs collapsed, mostly those flat-roofed tourist rentals down along the headland. Just cleaning up the docks is going to be a huge project. The Provisional Government contracted a bunch of earthmovers to clean the roads, and once some mobility is established they can start pumping seawater and sluice it all into the bay, assuming the storm sewers accommodate the runoff. All this is complicated by dust in motors, stalled cars and so forth."

"Any word on toxicity?"

"According to the news guys the ash is mostly carbon, sulfur, silicates, and metals, some of it arranged in unusual molecules, whatever that means, but breaking down pretty quick into simpler elements. Short-term it's not dangerous unless you've got asthma or emphysema. Long-term, who knows? They still want people to stay indoors, and they're advising a face mask if you really need to go out."

"Anybody making any guesses about where it all came from?"

"No. We're getting a lot of speculation, mostly bullshit, but somebody at the Geophysical Survey had the same idea we did—that it's spaceborne material that's been modified by the Hypotheticals."

In other words, nobody really knew anything. "Did you sleep last night?"

"Not much."

"Had any breakfast?"

"Didn't want to mess up your kitchen."

"I'm not much of a cook, but I can do omelettes and coffee." When he offered to help she said, "You'd just be in the way. Give me twenty minutes."

There was a window in the kitchen, and Lise was able to survey the Port while butter sizzled in the frying pan—this big, polyglot, kaleido-scopically multicultural city that had grown so quickly on the edge of a new continent, now blanketed in ominous gray. The wind had stiffened overnight. The ash had duned in the empty streets and it shivered down from the crowns of the trees that had been planted along Rue Abbas.

She sprinkled fresh cheddar onto the omelette and folded it. For once it didn't break and spill off the spatula in a gooey lump. She put together two plates and carried them into the living room. She found Turk standing in the space she used for an office: a desk, her keyboard and file holders, a small library of paper books.

"This where you write?" he asked.

"Yes." No. She put the plates on the coffee table. Turk joined her on the sofa, folding his long legs and taking the plate onto his lap.

"Good," he said, sampling the omelette.

"Thank you."

"So that book you're working on," he said. "How's that going?"

She winced. The book, the notional book, her excuse for prolonging her stay in Equatoria, didn't exist. She told people she was writing a book because she was a journalism graduate and because it seemed a plausible thing for her to do in the aftermath of a failed marriage—a book about her father, who had vanished without explanation when the family lived here a dozen years ago, when she was fifteen. "Slowly," she said.

"No progress?"

"A few interviews, some good conversations with my father's old colleagues at the American University." All this was true. She had immersed herself in her family's fractured history. But she hadn't written more than notes to herself.

"I remember you said your father was interested in Fourths."

"He was interested in all kinds of things." Robert Adams had come to Equatoria as part of the Geophysical Survey's deal with the fledgling American University. The course he taught was New World Geology and he had done fieldwork in the far west. The book he had been working on—a real book—had been called Planet as Artifact, a study of the New World as a place where geological history had been deeply influenced by the Hypotheticals.

And, yes, he had also been fascinated by the community of Fourths—privately, not professionally.

"The woman in the photograph you showed me," Turk said. "Is she a Fourth?"

"Maybe. Probably." How much of this did she really want to discuss?

"How can you tell?"

"Because I've seen her before," Lise said, putting down her fork and turning to face him. "Do you want the whole story?"

"If you want to tell it."

Lise had heard the word "disappeared" applied to her father for the first time three days after he failed to come home from the university, a month after her fifteenth birthday. The local police had come to discuss the case with Lise's mother while Lise listened from the corridor outside the kitchen. Her father had "disappeared"—that is, he had left work as usual, had driven away in the customary direction, and somewhere between the American University and their rented house in the hills above Port Magellan he had vanished. There was no obvious explanation, no pertinent evidence.

But the investigation went on. The issue of his fascination with Fourths had come up. Lise's mother was interviewed again, this time by men who wore business suits rather than uniforms: men from the Department of Genomic Security. Mr. Adams had expressed an interest in Fourths: was the interest personal? Had he, for instance, repeatedly mentioned the subject of longevity? Did he suffer from any degenerative disease that might have been reversed by the Martian longevity treatment? Was he unusually concerned with death? Unhappy at home?

No, Lise's mother had said. Actually, what she said most often was "No, goddammit." Lise remembered her mother at the kitchen table, interrogated, drinking endless cups of rust-brown roiboos tea and saying, "No, goddammit, no."

Nevertheless, a theory had emerged. A family man in the New World, often apart from his family, seduced by the anything-goes atmosphere of the frontier and by the idea of the Fourth Age, an extra thirty years or so tacked onto his expected span of life…

Lise had to admit there was a certain logic to it. He wouldn't have been the first man to be lured from his family by the promise of longevity. Three decades ago the Martian Wun Ngo Wen had brought to Earth a technique for extending human life—a treatment that changed behavior in other and subtler ways as well. Proscribed by virtually every government on Earth, the treatment circulated in the underground community of Terrestrial Fourths.

Would Robert Adams have abandoned his career and family to join that community? Lise's instinctive answer was the same as her mother's: no. He wouldn't have done that to them, no, no matter how tempted he might have been.

But evidence had emerged to subvert that faith. He had been associating with strangers off-campus. People had been coming to the house, people not associated with the university, people he had not introduced to his family and whose purposes he had been reluctant to explain. And the Fourth cults held a special appeal in the academic community—the treatment had first been circulated by the scientist Jason Lawton, among friends he considered trustworthy, and it had spread primarily among intellectuals and scholars.

No, goddammit—but did Mrs. Adams have a better explanation?

Mrs. Adams did not. Nor did Lise.

The investigation remained inconclusive. After a year of this Lise's mother had booked passage to California for herself and her daughter, bent by the insult to her well-planned life but not, at least outwardly, broken. The disappearance—the New World in general—became a subject one didn't mention in her presence. Silence was better than speculation. Lise had learned that lesson well. Like her mother, Lise had secured her pain and curiosity in the dark internal attic where unthinkable thoughts were stored. At least until her marriage to Brian and his transfer to Port Magellan. Suddenly those memories were refreshed: the wound reopened as if it had never healed, and her curiosity, she discovered, had been distilled in its enclosure, had become an adult's curiosity rather than a child's.

So she had begun to ask questions of her father's colleagues and friends, the few still living in the city, and inevitably these questions had involved the community of Fourths in the New World.

Brian at first tried to be helpful. He hadn't much liked her ad hoc investigation into what he considered potentially dangerous matters—and Lise supposed it had been one more in a growing number of emotional disconnects between them—but he had tolerated it and even used his DGS credentials to follow up on some of her queries.

Like the woman in the photograph.

"Two photographs, actually," she told Turk. When she moved out of her mother's house, Lise had salvaged a number of items her mother was forever threatening to throw away, in this case a disk of photographs from her parents' Port Magellan years. A few of the pictures had been taken at faculty parties at the Adams' house. Lise had selected a few of these photos and shown them to old family friends, hoping to track down those she didn't recognize. She managed to put names, at least, to most of them, but one stood out: a dark-skinned elderly woman in jeans, caught standing in the doorway beyond a crowd of far more expensively-dressed faculty members, as if she had arrived unexpectedly. She seemed disconcerted, nervous.

No one had been able to identify her. Brian had offered to run the picture through DGS image-recognition software and see if anything turned up. This had been the latest of what Lise had come to think of as Brian's "charity bombs"—acts of generosity he threw in front of her as if to divert her from the path to separation—and she had accepted the offer with a warning that it wouldn't change anything.

But the search had turned up a pertinent match. The same woman had passed through the docks at Port Magellan just months ago. She had been listed on a passengership manifest as Sulean Moi.

The name turned up again in connection with Turk Findley, who had piloted the charter flight that carried Sulean Moi over the mountains to the desert town of Kubelick's Grave—the same town to which Lise had been attempting to fly a few months before, following a different lead.

Turk listened to all this patiently. Then he said, "She wasn't talkative. She paid cash. I put her down at the airstrip in Kubelick's Grave and that was that. She never said anything about her past or why she was flying west. You think she's a Fourth?"

"She hasn't changed much in fifteen years. That suggests she might be."

"So maybe the simplest explanation is true. Your father took the illegal treatment and started a new life under a new name."

"Maybe. But I don't want another hypothesis. I want to know what really happened."

"So you find out the truth, what then? Does that make your life better? Maybe you'll learn something you don't like. Maybe you have to start mourning all over again."

"At least," she said, "I'll know what I'm mourning for."

As often happened when she talked about her father, she dreamed of him that night.

More memory than dream at first: she was with him on the veranda of their house on the hill in Port Magellan, and he was talking to her about the Hypotheticals.

He talked to her on the veranda because Lise's mother didn't care for these conversations. This was the starkest contrast Lise could draw between her parents. Both were Spin survivors, but they had emerged from the crisis with polarized sensibilities. Her father had thrown himself headlong into the mystery, had fallen in love with the heightened strangeness of the universe. Her mother pretended that none of it had happened—that the garden fence and the back wall were barricades strong enough to repulse the tide of time.

Lise had not quite known where to place herself on that divide. She loved the sense of safety she felt in her mother's home. But she loved to hear her father talk.

In the dream he talked about the Hypotheticals. The Hypotheticals aren't people, Lise, you must not make that mistake. As the unnamed Equatorian stars turned in the slate-black sky. They are a network of more or less mindless machines, we suspect, but is that network aware of itself? Does it have a mind, Lise, the way you and I do? If it does, every element of its thought must be propagated over hundreds or thousands of light-years. It would see time and space very differently than we do. It might not perceive us at all, except as a passing phenomenon, and if it manipulates us it might do so at an entirely unconscious level.

Like God, Lise in her dream suggested.

A blind God, her father said, but he was wrong, because in the dream, while she was entranced in the grandeur of his vision and safe in the boundary of her mothers sensibility, the Hypothetical had reached down from the sky, opened a steel fist that glittered in the starlight, and snatched him away before she could summon the courage to scream.

CHAPTFR FIVE

The dust fell more sparsely for another few hours, yielded to a gray daylight, and stopped altogether by dark. The city remained eerily quiet apart from the intermittent growl of earthmovers ceaselessly shifting the ash. Turk could tell where the earth-movers were working by the billows of fine dust that rose around and above them, gray pillars lofting over the corduroy of shops, shanties, office buildings, billboards, commingling with saltwater plumes where pump lines laid from the harbor to the hills had begun to sluice the streets. A wasteland. But even at this hour there were people in the street, masked or with bandannas tied over their faces, kicking through the drifts on their way somewhere or just assessing the damage, gazing around like bit players in a disaster drama. A man in a grimy dishdasha stood for half an hour outside the locked Arabic grocery across the street, smoking cigarettes and staring at the sky.

"You think it's over?" Lise asked.

Obviously a question he couldn't answer. But he guessed she didn't want a real answer as much as she wanted reassurance. "For now, anyway."

They were both too wired to sleep. He switched on the video display and they settled back on the sofa, trawling for new information. A newsreader announced that the dust cloud had moved inland and no more "precipitation" was expected—there had been sporadic reports of ashfall from every community between Ayer's Point and Haixi on the coast, but Port Magellan seemed to have been hit harder than most. Which was in a way a good thing, Turk supposed, because while this dump of particulate matter had been troublesome for the city it might have been a catastrophe for the local ecosystem, smothering forests and killing crops and maybe even poisoning the soil, though the newscaster said there was nothing terribly toxic in it, "according to the latest analyses." The fossil - or machine-like structures in the ashfall had attracted attention, of course. Microphotographs of the dust revealed even more latent structure: degraded cogs and wheels, scalloped cones like tiny conch shells, inorganic molecules hooked together in complex and unnatural ways—as if some vast machine had eroded in orbit and only its finer elements had survived the fiery descent through the atmosphere.

They had spent the day in the apartment, Turk mostly sitting at the window, Lise making calls and sending messages to family back home, itemizing the food in the kitchen in case the city was shut down long-term, and in the process they had reestablished a kind of intimacy—the mountain-camp-in-a-thunderstorm intimacy they had shared before, brought down to the city—and when she put her head against his shoulder Turk raised his hand to stroke her hair, hesitated when he remembered the nature of their situation here.

"It's all right," she said.

Her hair smelled fresh and somehow golden, and it felt like silk under the palm of his hand.

"Turk," she said, "I'm sorry—"

"Nothing to apologize for."

"For thinking I needed an excuse to see you."

"Missed you too," he said.

"Just—it was confusing."

"I know."

"Do you want to go to bed?" She took his hand and rubbed her cheek against it. "I mean—"

He knew what she meant.

He spent that night with her and he spent another, not because he had to—the coast road had been mostly cleared by that time—but because he could.

But he couldn't stay forever. He lazed around one morning more, picking over breakfast while Lise made more calls. Amazing how many friends and acquaintances and home-folks she had. It made him feel a little unpopular. The only calls he made that morning were to customers whose flights would have to be rescheduled or canceled—cancellations he couldn't afford right now—and to a couple of buddies, mechanics from the airport, who might wonder why he wasn't around to go drinking with them. He didn't have much of a social life. He didn't even own a dog.

She recorded a long message to her mother back in the States. You couldn't make a direct call across the Arch, since the only things the Hypothetical allowed to travel between this world and the one next door were manned ocean vessels. But there was a fleet of telecom-equipped commercial ships that shuttled back and forth to relay recorded data. You could watch video news from home that was only a few hours stale, and you could send voice or text the other direction. Lise's message, what he overheard of it, was a careful reassurance that the ashfall had done no lasting harm and looked like it would be cleared up before long, although it was a mystery why it had happened, very confusing—no shit, Turk thought.

Turk had family in Austin, Texas. But they hadn't heard from him lately and wouldn't expect to.

On the bookshelf by Lise's desk was a three-volume bound copy of the Martian Archives, sometimes called the Martian Encyclopedia, the compendium of history and science brought to earth by Wun Ngo Wen thirty years ago. The blue dust jackets were tattered at their spine ends. He took down the first volume and leafed through it. When she finally put down the phone, he said, "Do you believe in this?"

"It's not a religion. It's not something you have to believe in it."

Back during the freakish years of the Spin, the technologically advanced nations of the Earth had assembled the necessary resources to terraform and colonize the planet Mars. The most useful resource had already been put in place by the Hypotheticals, and that was time. For every year on Earth under the Spin membrane, thousands of years had passed in the universe at large. The biological transformation of Mars—scientists called it "the ecopoiesis"—had been relatively easy to accomplish, given that generous temporal disconnect. The human colonization of the planet had been an altogether riskier venture.

Isolated from Earth for millennia, the Martian colonists had created a technology suited to their water-poor and nitrogen-starved environment. They were masters of biological manipulation but chronically wary of large-scale mechanical engineering. Sending a manned expedition to Earth had been a last, desperate strategy when the Hypotheticals appeared to be about to enclose Mars in a Spin membrane of its own.

Wun Ngo Wen, the so-called Martian ambassador—Turk found a photograph of him as he leafed through an appendix to the book: a small, wrinkled, dark-skinned man—had arrived during the last years of the Spin. He had been feted by Earthly governments, until it became clear that he possessed no magic solution to their problems. But Wun had advocated and helped set in motion the launch of Martian-designed quasi-biological probes into the outer solar system—self-replicating robotic devices that were supposed to broadcast back information that might shed useful light on the nature of the Hypotheticals, and in a way they had succeeded—the network of probes had been absorbed into a preexisting, previously unsuspected ecology of self-replicating devices living in deep space, which was the physical "body" of the Hypotheticals, or so some people believed. But Turk had no opinion about that.

The version of the Archives Lise possessed was an authorized redaction, published in the States. It had been vetted and organized by a panel of scientists and government officials and it was acknowledged to be incomplete. Before his death Wun had arranged for unedited copies of the text to be privately circulated, along with something even more valuable—Martian "pharmaceuticals," including the drug that would add some thirty or more years to an average human life span, the so-called Fourth treatment by which Lise's father had presumably been tempted.

There were supposedly lots of native Fourths on Earth now, though they lacked the elaborate social structures that constrained the lives of their Martian cousins. Taking the treatment was illegal under a UN accord signed by virtually every member nation. Most of what the Department of Genomic Security did back in the States was shutting down Fourth cults both genuine and fraudulent—that, and policing the booming trade in human and animal genetic enhancements. These were the folks Lise's ex-husband worked for.

"You know," she said, "we haven't talked much about this."

"We haven't talked nearly enough about anything at all, seems to me."

Her smile, though brief, was pleasing.

She said, "Do you know any Fourths?"

"Wouldn't recognize one if I saw one." And if that was an evasion, she didn't appear to notice.

"Because it's different here in the Port," she said, "here in the New World. The laws aren't enforced the way they are back on Earth."

"That's changing, I hear."

"Which is why I want to look at what my father was interested in before it all gets erased. People say there's a Fourth underground in the city. Maybe more than one."

"Yeah, I've heard that. I've heard a lot of things. Not all true."

"I can do all the secondhand research I want, but what I really need is to talk to someone who's had direct experience with the Fourth community here."

"Right. Maybe Brian can arrange it for you, next time DGS arrests somebody."

He was immediately sorry he'd said it, or said it so bluntly. She tightened up. "Brian and I are divorced, and I'm not responsible for what Genomic Security does."

"But he's looking for the same people you're looking for."

"For different reasons."

"Do you ever wonder about that? Whether he might be using you as some kind of cat's paw? Riding on your research?"

"I don't show my work to Brian—to anyone."

"Not even when he's baiting you with the woman who maybe took away your father?"

"I'm not sure you have the right—"

"Forget it. I'm just, you know, concerned."

She was obviously on the verge of handing that right back to him, but she cocked her head and thought about it first. That was one of the things Turk had noticed about her right away, the habit she had of stepping outside the moment before she rendered a verdict.

She said, "Don't make assumptions about me and Brian. Just because we're still on speaking terms doesn't mean I'm doing him favors."

"Just so we know where we are," he said.

The sky was gray again by noon, but the clouds were rain clouds, nothing exotic, and they brought a drenching, unseasonable downpour. Turk guessed the rain might ultimately be a boon—it would wash some of this ash into the soil or out to sea, maybe help salvage the season's crops, if that was possible. But it did nothing to ease the drive south from the Port, once he recovered his car from the parking lot at Harley's. Glistening washes of gray ash made the pavement treacherous. Creeks and rivers had turned the color of clay and ran turgidly in their beds. When the road crossed the high ridges Turk could see a bloom of silt tailing into the sea from a dozen muddy deltas.

He left the coast road at an unmarked exit toward a place most English-speakers called New Delhi Flats, a shanty settlement on a plateau between two creeks, under a sheer bluff that crumbled a little every rainy season. The alleys between the rows of cheap Chinese-branded prefab housing were unpaved, and the fair-weather huts had been improved with tarpaper roofing and sheets of insulation hauled in from cheapjack factories up-coast. There were no police in the Flats, no real authority beyond what could be leveraged by the churches, temples, and mosques. The earthmovers hadn't been anywhere near the Flats, and the narrower alleys were congested with sloggy wet dunes. But a passage had been shoveled along the main avenue, and it took Turk only a few extra minutes to reach Tomas Ginn's undistinguished home—an arsenic-green hovel squeezed between two just like it.

He parked and waded through a thin gruel of wet ash to Tomas's door. He knocked. When there was no answer he knocked again. A lined face appeared briefly at the small curtained window to his left. Then the door swung open.

"Turk!" Tomas Ginn had a voice that sounded as if it had been filtered through bedrock, an old man's voice, but firmer than it had been when Turk first encountered him. "Didn't expect to see you. Specially in the middle of all this trouble. Come on in. Place is a fuckin' mess but I can pour you a drink, anyhow."

Turk stepped inside. Tomas's home was little more than a single thin-walled room with a raggedy sofa and table at one end and a miniature kitchen at the other, all dimly lit. The Port Magellan Power Authority hadn't strung any cables out this way. The only electricity came from an array of Sinotec photovoltaics on the roof, and their efficiency had been slashed by the dustfall. The place had a lingering aroma of sulfur and talc, but that was mostly the ash Turk had tracked in with him. Tomas was a fastidious housekeeper, in his own way. A "fuckin' mess," in Tomas's vocabulary, meant there were a couple of empty beer bottles undisposed-of on a narrow counter.

"Sit on down," Tomas said, settling himself on a chair with a dent in the seat that had been worn into a mirror image of his bony ass. Turk selected the least-tattered cushion on his friend's ancient sofa. "Can you believe this shit falling out of the sky? I mean, who asked for that! I had to shovel my way out of the house yesterday just to go out and get groceries."

Pretty unbelievable, Turk acknowledged.

"So what brings you here? Something more than neighborliness, I expect, given the weather. If you can call it weather."

"Got a question to ask," Turk said.

"A question or a favor?"

"Well—starts with a question, anyway."

"Serious?"

"It might be."

"So you want a beer? Get the dust out of your throat?"

"Not a bad idea," Turk said.

Turk had met Tomas aboard an ancient single-hulled tanker bound for Breaker Beach on its final voyage.

The ship, called Kestrel, had been Turk's ticket to the New World. Turk had signed on as an able-bodied seaman at negligible wages. All the crew had, because it was a one-way trip. Across the Arch, in Equatoria, the market for scrap iron and steel was booming. On Earth a leviathan like the Kestrel was a liability, too old to meet international standards and useless for anything but the poorest kind of coastal trade, prohibitively expensive to scrap. But in the New World the same rusty hulk would be a source of valuable raw material, stripped and diced by the acetylene-wielding armies of Thai and Indian laborers who made their living unrestrained by environmental regulations—the professional breakers of Breaker Beach, located some hundred miles north of Port Magellan.

Turk and Tomas had shared a mess on that voyage and learned a few things about each other. Tomas claimed to have been born in Bolivia, but he had been raised, he said, in Biloxi, and had worked the docks in that city and then New Orleans as a boy and young man. He had been at sea off and on for decades, during the tumultuous years of the Spin, when the U.S. government had revived the old Merchant Marine as a gesture toward national security, and afterward, when trade across the Arch created fresh demand for new shipping.

Tomas had joined Kestrel for the same reason Turk had signed on: it was a one-way ticket to the promised land. Or what they both liked to imagine was a promised land. Tomas wasn't naive: he had crossed the Arch five times before, had spent months in Port Magellan, knew the towns vices firsthand, and had seen how cruelly the town could treat newcomers. But it was a freer, more open, more casually polyglot city than any on Earth—a seaman's town, much of it built by expatriate sailors, and it was where he wanted to spend the last years of his life, looking at a landscape on which human hands had only recently been laid. (Turk had signed on for much the same reason, though it would be his first trip cross-Arch. He had wanted to get as far from Texas as it was practical to get, for reasons he didn't care to dwell on.)

The trouble with Kestrel was that, because it had no future, it had been poorly maintained and was barely seaworthy. Everyone aboard was aware of that fact, from the Filipino captain down to the illiterate Syrian teenager who stewarded the crew mess. It made for a dangerous transit. Bad weather had scuttled many a vessel bound for Breaker Beach, and more than one rusty keel had gone to rest under the Arch of the Hypotheticals.

But the weather in the Indian Ocean had been reassuringly benign, and because this was Turk's first passage he had risked the derision of his shipmates by arranging to be on deck when the crossing happened.

A night crossing of the Arch. He staked out a place aft of the forecastle out of the breeze, made a pillow from a hank of rag stiff with dried paint, stretched out and gazed at the stars. The stars had been scattered by the four billion years of galactic evolution that had transpired while the Earth was enclosed in its Spin membrane, and they remained nameless after thirty years, but they were the only stars Turk had ever known. He had been barely five years old when the Spin ended. His generation had grown up in the post-Spin world, accustomed to the idea that a person could ride an ocean vessel from one planet to another. Unlike some, however, Turk had never been able to make that fact seem prosaic. It was still a wonder to him.

The Arch of the Hypotheticals was a structure vastly larger than anything human engineering could have produced. By the scale of stars and planets, the scale on which the Hypotheticals were assumed to operate, it was a relatively small thing… but it was the biggest made thing Turk imagined he would ever encounter. He had seen it often enough in photographs, on video, in representative diagrams in schoolbooks, but none of those did justice to the real item.

He had first seen it with his own eyes from the Sumatran port where he joined the Kestrel. The Arch's eastern leg had been visible on clear days and especially at sunset, when the last light climbed that pale thread and burnished it to a fine golden line. But now he was almost directly beneath the apex, a different view entirely. The Arch had been compared to a thousand-mile-wide wedding ring dropped into the Indian Ocean, half of it embedded in the bedrock of the planet and the other half projecting above the atmosphere into naked space. From the deck of the Kestrel he couldn't see either leg where it entered the sea, but he could see the peak of the Arch reflecting the last light of the sun, a brushstroke of silvery-blue fading to dusky red at its eastern and western extremities. It quivered in the heat of the evening air.

Up close, people said, if you sailed within hailing proximity of either leg, it looked as plain as a pillar of concrete rising from the surface of the sea, except that the enormously wide pillar didn't stop rising, simply vanished from sight. But the Arch wasn't an inert object no matter how static it appeared. It was a machine. It communicated with a copy of itself—or the other half of itself, perhaps—set in the compatible ocean of the New World, many light-years distant. Maybe it orbited one of the stars Turk could see from the deck of the Kestrel: there was a shivery thought. The Arch might appear to be inanimate, but in fact it was watching the near surface of both worlds, conducting two-way traffic. Because that was what it did: that was its function. If a bird, a storm-tossed tree limb, or an ocean current passed beneath the Arch it would continue on its way unmolested. The waters of Earth and the New World never mingled. But if a manned ocean vessel crossed under the Arch it would be picked up and translated across an unimaginable distance. By all reports the transition was so easy as to be almost anticlimactic, but Turk wanted to experience it out here in the open, not down in crew quarters where he wouldn't even know it had happened until the ship sounded its ritual horn.

He checked his watch. Almost time. He was still waiting when Tomas stepped out of the shadows into the glare of a deck light, grinning at him.

"First time, yeah," Turk said, forestalling the inevitable comment.

"Fuck," Tomas said, "you don't need to explain. I come out every time I pass. Day or night. Like paying respects."

Respects to whom? The Hypothetical? But Turk didn't ask.

"And, oh my!" Tomas said, aiming his old face at the sky. "Here it comes."

So Turk braced himself-—unnecessarily—and watched the stars dim and swirl around the peak of the Arch like watery reflections stirred by the prow of a boat. Then suddenly there was fog all around the Kestrel, or a mistiness that reminded him of fog although it had no scent or taste of moisture to it—a transient dizziness, a pressure in his ears. Then the stars came back, but they were different stars, thicker and brighter in what seemed like a blacker sky; and now the air did taste and smell subtly different, and a gust of it swirled around the hard steel angles of the topdeck as if to introduce itself, air warm and salt-scented and bracingly fresh. And up on the high bridge of the Kestrel, the compass needle must have swung on its pivot, as compasses did at every crossing of the Arch, because the ship's horn sounded one long wail—punishingly loud but sounding almost tentative across an ocean only lately acquainted with human beings.

"The New World," Turk said, thinking, That's it? As easy as that?

"Equatoria," Tomas said, confusing the continent with the planet as most people did. "How's it feel to be a spaceman, Turk?"

But Turk couldn't answer, because two crewmen who had been stealthily pacing the topdeck rounded on Turk with a bucket of saltwater and doused him, laughing. Another rite of passage, a christening for the virgin sailor. He had crossed, at last, the world's strangest meridian. And he had no intention of going back, no real home to go back to.

Tomas had been frail with age when he boarded the Kestrel, and he was injured when the beaching of the vessel went bad.

There were no docks or quays at Breaker Beach. Turk had seen it from the deck rail, his first real look at the coast of Equatoria. The continent loomed out of the horizon like a mirage, pink with morning light, though hardly untouched by human hands. The three decades since the end of the Spin had transformed the western fringe of Equatoria from a wilderness into a chaos of fishing villages, lumber camps, primitive industry, slash-and-burn farmland, hasty roads, a dozen booming towns, and one city through which most of the hinterlands rich resources were channeled. Breaker Beach, almost a hundred nautical miles north of Port Magellan, was possibly the ugliest occupied territory on the coast—Turk could hardly say, but the Filipino cargomaster insisted it was, and the argument was plausible. The broad white beach, protected from the surf by a pebbly headland, was littered with the corpses of broken vessels and smudged with the smoke and ash of a thousand fires. Turk spotted a double-hulled tanker not unlike the Kestrel, a score of coastal tankers, even a military vessel stripped of all identifying flags and markings. These were recent arrivals, the work of their deconstruction hardly begun. For many miles more the beach was crowded with steel frames denuded of hull plating, cavernous half-ships in which the acetylene glare of the breakers' torches made a fitful light.

Beyond that lay the scrap-metal huts and forges and toolsheds and machine shops of the breakers, mostly Indian and Malaysian men working out the contracts that had bought them passage under the Arch. Farther on, hazy in the morning air, forested hills unrolled into the blue-gray foothills of the mountains.

He couldn't stay on deck during the beaching. The standard way to deliver a large vessel to Breaker Beach was simply to run it up the littoral and strand it there. The breakers would do the rest, swarming over the ship once the crew had been evacuated. The ship's steel would end up in re-rolling mills downcoast, the ship's miles of wiring and aluminum piping would be extracted and sold in bulk lots, even the ship's bells, Turk had heard, would be marketed to local Buddhist temples. This was Equatoria, and any manmade thing would find a use. It didn't matter that beaching a vessel as enormous as the Kestrel could be a violent, destructive process. None of these ships would ever float again.

He went belowdecks when the signal sounded and found Tomas waiting in the crew mess, grinning. Turk had grown fond of Tomas's bony grin—demented-looking but genuine. "End of the road for Kestrel," Tomas said, "and the end of the road for me, too. Every chicken comes home to roost, I guess."

"We're positioned off the beach," Turk said. Soon the captain would start the engines and engage the screws and send the ship dead for shore. The engines would be shut down at the last practical moment and the prow of the ship would gully into the sand while the tide was high. Then the crew would drop rope ladders and scurry down the hull; their kit bags would be lowered; Turk would take his first steps in the grit and wash of Breaker Beach. Within a month Kestrel would be little more than a memory and a few thousand tons of recycled iron, steel, and aluminum.

"Every death is a birth," said Tomas, who was old enough to get away with such pronouncements.

"I wouldn't know about that."

"No. You strike me as somebody who knows more than he lets on. End of Kestrel. But your first time in the New World. That's a death and a birth right there."

"If you say so, Tomas."

Turk felt the ship's elderly engines begin to throb. The beaching would be violent, inevitably. All the loose gear in the ship had already been stowed or dismounted and sent ashore along with the lifeboats. Half the crew was already ashore. "Whoa," Tomas exclaimed as the vibration came up through the deck plating and the chair legs. "Making some speed now, you bet."

The prow of the ship would be cutting a knife-edge through the water, Turk thought, as it did whenever the vessel began to throb and surge like this. Except they weren't in open water anymore. Their slot on the beach was dead ahead, the continent rising beneath them. The captain was in radio contact with a shore pilot who would call in minor course corrections and tell him when to cut the engines.

Soon, Turk hoped. He liked being at sea, and he didn't mind being belowdecks, but he found he very much disliked being in a windowless room when a deliberately-engineered disaster was only moments away. "You done this before?"

"Well, no," Tomas said, "not from this end. But I was at a wreckers' beach near Goa a few years ago and I watched an old container ship ground itself. Ship not much smaller than this one. Kind of a poetry to it, actually. It rode up the tideline like one of those turtles trying to lay an egg. I mean, I guess you want to brace yourself for it, but it wasn't violent." A few minutes later Tomas looked at the watch that hung like a bracelet on his skinny wrist and said, "About time to cut engines."

"You got it timed?"

"I got eyes and ears. I know where we were anchored and I can tell by listening what kind of speed we're making."

This sounded to Turk like one of Tomas's boasts, but it might be true. Turk wiped his palms on the knees of his jeans. He was nervous, but what could go wrong? At this point it was all ballistics.

What did go wrong—as he sorted it out afterward—was that at a critical moment Kestrel's bridge lost electrical power, due to some short or component failure in the antique circuitry, so that the captain could neither hear the shore pilot's instructions nor relay his orders to the engine room. Kestrel should have come in coasting, but she beached under power instead. Turk was thrown from his chair as the ship ground into the littoral and listed grotesquely to starboard. He was alert enough to see the brushed-steel cutlery locker break loose from the near wall and tumble toward him. The locker was the size of a coffin and about as heavy, and he tried to crawl away from it, but there wasn't time to pull himself out of the way. But here was Tomas, somehow still upright, grabbing for the screeching metal box and managing to snag the corner of it as it slid by, giving Turk enough time to scramble aside. He fetched up against a chair as Kestrel stopped moving and the ship's engines finally, mercifully, died. The old tanker's hull gave a ratcheting, prehistoric groan and fell silent. Beached. No harm done…

Except to Tomas, who had briefly taken the full weight of the locker and whose left arm had been sliced open below the elbow, deep enough to show bone.

Tomas cradled the injury in his blood-soaked lap, looking startled. Turk applied a handkerchief as a tourniquet and told his friend to stop cursing and keep still while he went for help. It took him ten minutes to find an officer who would listen to him.

The ship's doctor had already gone ashore and the infirmary had been stripped of drugs, so Tomas had to be lowered from the deck in an improvised rope-and-basket litter with only a couple of aspirin to dull the pain. The Kestrel's captain, in the end, refused to admit liability, collected his pay from the breaker boss, and caught a bus for Port Magellan before sunset. So Turk was left to look after Tomas until an off-shift Malay welder could be convinced to summon a genuine doctor. Or what passed for a doctor in this part of the New World. A woman, the skinny Malay said in broken English. A good doctor, a Western doctor, very kind to the breakers. She was white but had lived for years in a Minang fishing village not far upcoast.

Her name, he said, was Diane.

CHAPTER SIX

Turk told Tomas Ginn about Lise—a little bit about her. How they had connected when they were stranded in the mountains; how he couldn't get her out of his mind even when they were back in civilization, even when she stopped returning his calls; how they got back together during the ashfall.

Tomas listened from his tattered easy chair, sipping beer from a green glass bottle and smiling placidly, as if he had discovered some kind of windless place inside his head. "Sounds like you hardly know this lady."

"I know as much as I need to. Some people, it isn't that hard to tell whether you trust them or not."

"Trust her, do you?"

"Yeah."

Tomas cupped the crotch of his baggy jeans. "This is what you trust. Every inch a sailor."

"It's not like that."

"It never is. But it always is. So why you want to drive up here and tell me about this woman?"

"Actually, I was thinking maybe I could introduce her to you."

"To me? I ain't your daddy, Turk."

"No, and you're not what you used to be, either."

"Don't see what that's got to do with it."

Turk had to tread carefully here. With the utmost delicacy, insofar as he was capable of it. "Well… she's curious about Fourths."

"Oh, my Christ." Tomas rolled his eyes. "Curious?"

"She's got reasons to be."

"So you want to serve me up to her? Exhibit A or whatever?"

"No. What I really want to do is let her talk to Diane. But I want your opinion first."

Diane—the Western doctor, or nurse, as she insisted on calling herself—had hiked to Breaker Beach from some inland village to treat Tomas's slashed arm.

At first Turk was suspicious of her. In Equatoria, especially out here in the backwoods, nobody was checking anybody's medical license. At least that was the impression he got. If you owned a syringe and a bottle of distilled water you could call yourself a doctor, and the breaker bosses would naturally endorse any self-appointed physician who worked for free, regardless of results. So Turk sat with Tomas inside a vacant hut waiting for this woman to arrive, making occasional conversation until the older man fell asleep despite the blood still leaking into his makeshift bandage. The hut was made of some local wood, round barked branches knobbed like bamboo holding up a flat tin roof. It smelled of stale cooking and tobacco and human sweat. It was hot inside, though the screened door admitted an occasional slow sigh of air.

The sun was going down when the doctor finally walked up the plank steps to the platform floor, tugging aside a layer of bug netting.

She wore a tunic and loose pants of a cloth the color and texture of raw muslin. She wasn't a young woman. Far from it. Her hair was so white it seemed almost transparent. "Who's the patient?" she asked, squinting. "And light a lamp, please—I can hardly see."

"My name's Turk Findley," Turk said.

"Are you the patient?"

"No, I—"

"Show me the patient."

So he turned up the wick of an oil lamp and escorted her through another layer of netting to the yellowed mattress where Tomas slept. Out in the dusk, insect choruses were warming up. They sounded like no insects he had heard before, but you could tell that's what it was, that steely staccato buzzing. From the beach came the sound of hammering, the clatter of sheet metal, the chug and whine of diesel motors.

Tomas snored, oblivious. The doctor—Diane—looked at the bandage on his arm with an expression of contempt. "How did this happen?"

Turk told her how it had happened.

"So he sacrificed himself for you?"

"Sacrificed a chunk of his arm, anyhow."

"You're lucky to have a friend like that."

"Wake him up first. Then tell me whether I'm lucky."

She nudged Tomas's shoulder and Tomas opened his eyes and promptly cursed. Old curses, Creole curses, pungent as gumbo. He tried to sit up, then thought better of it. Finally he fixed his attention on Diane. "And who the fuck might you be?"

"I'm a nurse. Calm down. Who bandaged you?"

"Guy on the ship."

"He did a lousy job. Let me see."

"Well, I guess it was his first time. He—ow! Jesus! Turk, is this a real nurse?"

"Don't be an infant," Diane said. "And hold still. I can't help you if I can't see what's wrong." A pause. "Ah. Well. You're lucky you didn't cut an artery." She took a syringe from her kit and filled it. "Something for the pain before I clean and stitch."

Tomas started to protest, but that was for show. He looked relieved when the needle went in.

Turk backed away and tried to give Diane room to work, not that there was a whole lot of space in this little hut. He wondered what it must be like to make a living as a breaker—to sleep under a tin roof praying you wouldn't be hurt or killed before your contract played out, before you got the payoff they promised you, a year's wages and a bus ticket to the Port. There was an official camp physician, the breaker boss had explained, but he only came in twice a week, usually to fill out forms. Diane did most of the routine cut-and-stitch duty.

Turk watched her as she worked, a silhouette cast by lamplight on the gauzy bug screen. She was skinny and she moved with the calculated caution of the very old. But she was strong, too. She worked methodically and smoothly, occasionally muttering to herself. She might be around Tomas's age, which the sailor variously gave as sixty or seventy—maybe older.

She worked, and from time to time Tomas swore with fierce intent but a certain drugged lethargy. There was a stink of antiseptic, and Turk stepped out into the rising dark. His first night in the New World. In the near distance there was a stand of flowering bushes he couldn't name, six-fingered leaves moving in an offshore breeze. The flowers were blue and smelled like cloves or cinammon or some other Christmas spice. Farther off, the lights and fires of the industrial beach guttered like lit fuses. And beyond the beach the ocean rolled in faint green phosphorescence, and the alien stars turned grand slow circles.

"There's a potential complication," Diane said when she had finished with Tomas.

She came and sat with Turk on the edge of the wooden platform that held the floor a foot or so above the ground. She had worked hard cleaning and closing Tomas's wound, and she mopped her forehead with a handkerchief. Her accent was American, Turk thought. A shade southern—Maryland, maybe, or those parts.

He asked her what kind of complications those might be.

"With luck, nothing serious. But Equatoria is a completely novel microbial environment—do you understand?"

"I may be dumb, but I'm not ignorant."

She laughed at that. "I apologize, Mr.—?"

"Findley, but call me Turk."

"Your parents named you Turk?"

"No, ma'am. But the family lived in Istanbul for a couple years when I was a kid. I picked up a little Turkish. And a nickname. So what are you saying—Tomas might come down with some local disease?"

"There are no native human beings on this planet, no hominids, no primates, nothing remotely like us. Most local diseases can't touch us. But there are bacteria and fungi that thrive in moist, warm environments, including the human body. Nothing we can't adjust to, Mr. Findley—Turk—and nothing so dangerous or communicable that it could be carried back to Earth. But it's still not a good idea to arrive in the New World with a challenged immune system or, in Mr. Ginn's case, an open wound bandaged by an idiot."

"Can't you give him some kind of antibiotic?"

"I did. But the local microorganisms don't necessarily respond to standard pharmaceuticals. Don't misunderstand. He's not ill, and in all likelihood he won't become ill, but there's a certain unavoidable risk. Are you a close friend of Mr. Ginn?"

"Not exactly. But like I said, he was trying to help me out when he got hurt."

"I'd prefer to keep him here a few days, under my observation. Is that all right?"

"Fine by me, but you might have to go some to convince Tomas. I'm not his keeper."

"Where are you headed, if you don't mind me asking?"

"Downcoast to the city."

"Any particular address? A number where I can reach you?"

"No, ma'am. I'm new here. But you can tell Tomas I'll look for him at the union hall when he makes it down to Port Magellan."

She seemed disappointed. "I see."

"Or maybe I can call you."

She turned and gazed at him for a long moment. Scrutinized him, actually. Turk started to feel a little awkward under that relentless stare. Then she said, "Okay. Let me give you a number."

She found a pencil in her kit bag and scribbled the number on the back of a Coast & Urban Coach Lines ticket stub.

"She was evaluating you," Tomas said. "I know that."

"Good instincts, that woman." "Yeah. That's the point," Turk said.

So Turk found a place to live in the Port and lived on his savings for a while and dropped by the Seaman's Union every now and then to look for Tomas. But Tomas never showed. Which, at first, didn't worry him much. Tomas could be anywhere. Tomas could have taken it into his head to cross the mountains, for all he knew. So Turk would have dinner or a drink and forget about his messmate; but when a month had passed he dug out the ticket stub and keyed the number scribbled on it.

What he got was an automated message that the number had been discontinued.

Which piqued his curiosity as well as his sense of obligation. His money was running out and he was getting ready to sign up for pipeline work, but he caught a ride upcoast and hiked a couple of miles to the breaker compound and started asking questions. One of the breaker bosses remembered Turk's face and told him his friend had got sick, and that was too bad, but they couldn't let a sick sailor take up time and attention, so Ibu Diane and some Minang fishermen had hauled the old man back to their village.

Turk bought dinner at a tin-roofed Chinese restaurant at the crossroads, then hitched a ride farther upcoast, to a horseshoe bay turning gaudy colors under the long Equatorian dusk. The driver, a salesman for some West African import firm, pointed Turk at an unpaved road and a sign marked in a curvilinear language Turk couldn't read. Minang village down that way, he said. Turk walked a couple of miles through the forest, and just as the stars were turning bright and the insects bothersome he found himself between a row of wooden houses with buffalo-horn eaves and a lantern-lit general store where men in box caps sat at cable-spool tables drinking coffee. He put on his best smile and asked a local for directions to Doctor Diane's clinic.

The pedestrian smiled back and nodded and called out to the coffee house. Two muscular young men hurried out and positioned themselves on each side of Turk. "We'll take you there," they said in English when Turk repeated his request—and they smiled, too, but Turk had the uneasy feeling he'd been politely but firmly taken into custody.

"I guess I was pretty fucked-up when you finally saw me," Tomas said.

"You don't remember?"

"Not much of it, no."

"Yeah," Turk said. "You were pretty fucked-up."

Pretty fucked-up, which in this case meant Tomas was bedridden, emaciated, gasping for breath in the back room of the big wooden building Diane called her "clinic." Turk had looked at his friend with something approaching horror.

"Jesus Christ, what happened to him?"

"Calm down," Ibu Diane said. Ibu was what the villagers called her. He gathered it was some kind of honorific.

"Is he dying?"

"No. Appearances to the contrary, he's getting well."

"All this from a cut on his arm?"

Tomas looked as if someone had stuck a hose down his throat and siphoned out his insides. Turk thought he had never seen a thinner man.

"It's more complicated than that. Sit down and I'll explain."

Outside the window of Diane's clinic, the Minang village was lively in the dark. Lanterns hung swaying from eaves and he could hear the sound of recorded music playing tinnily. Diane made coffee with an electric kettle and a French press, and the resulting brew was hot and dense.

There used to be two real doctors at the clinic, she said. Her husband and a Minang woman, both of whom had lately died of natural causes. Only Diane was left, and the only medicine she knew was what she had learned while acting as a nurse. Enough to keep the clinic going: it was an indispensable resource not only for this village but for a half-dozen nearby villages and for the impoverished breakers. Any condition she couldn't treat she referred to the Red Crescent clinic up the coast or the Catholic charity hospital in Port Magellan, though that was a long trip. In matters of cuts, cleanly broken bones, and common disorders, she was perfectly competent. She consulted regularly with a traveling physician from the Port who understood her situation and made sure she was supplied with basic medicines, sterile bandages, and so forth.

"So maybe you should have sent Tomas downcoast," Turk said. "He looks seriously ill to me."

"The cut on his arm was the least of his problems. Did Tomas tell you he had cancer?"

"Jesus, no. Cancer? Does he?"

"We brought him back here because his wound was infected, but the cancer showed up in simple blood tests. I don't have much in the way of diagnostic equipment, but I do have a portable imager—ten years old but it works like a charm. It confirmed the diagnosis, and the prognosis was very grave. Cancer is hardly an untreatable disease, but your friend had been avoiding doctors for far too long. He was deeply metastasized."

"So he is dying."

"No." Diane paused. Once again she riveted him with that stare, fierce and a little uncanny. Turk made an effort not to avert his own eyes. It was like playing stare-down with a cat. "I offered him an unconventional treatment."

"Like what, radiation or something?"

"I offered to make him a Fourth."

For a moment he was too startled to speak. Outside, the music played on, something tunelessly alien beaten out of a wooden xylophone and funneled through a cheap loudspeaker.

He said, "You can do that?"

"I can. I have."

Turk wondered what he had gotten himself into and how he could most efficiently extract himself from it. "Well… I guess it's not illegal here…"

"You guess wrong. It's just easier to get away with. And we have to be discreet. An extra few decades of life isn't something you advertise, Turk."

"So why tell me?"

"Because Tomas is going to need some help as he recovers. And because I think I can trust you."

"How could you possibly know that?"

"Because you came here looking for him." She startled him by smiling. "Call it an educated guess. You understand that the Fourth treatment isn't just about longevity? The Martians were deeply ambivalent about tinkering with human biology. They didn't want to create a community of powerful elders. The Fourth treatment gives and it takes away. It gives you an extra thirty or forty years of life—and I'm a case in point, if you haven't guessed—but it also rearranges certain human traits."

"Traits," Turk said, dry-mouthed. He had never, to his knowledge, spoken to a Fourth before. And that was what this woman claimed to be. How old was she? Ninety years? One hundred?

"Am I so frightening?"

"No, ma'am, not at all, but—"

"Not even a little?" Still smiling.

"Well, I—"

"What I mean to say, Turk, is that as a Fourth I'm more sensitive to certain social and behavioral cues than the majority of unmodified people. I can generally tell when someone's lying or being disingenuous, at least when we're face-to-face. Although, against sincere lies I have no defense. I'm not omniscient, I'm not especially wise, and I can't read minds. The most you might say is that my bullshit detector has been turned up a notch or two. And since any group of Fourths is necessarily under siege—from the police or from criminals, or both—that's a useful faculty to have. No, I don't know you well enough to say I trust you, but I perceive you clearly enough to say that I'm willing to trust you… do you understand?"

"I suppose so. I mean, I don't have anything against Fourths. Never thought much about it either way."

"That comfortable innocence is over. Your friend won't die of cancer, but he can't stay here, and he has a lot of adjustments to make. What I would like to do is discharge him into your care."

"Ma'am—uh, Diane—I don't know the first thing about taking care of a sick man, much less a Fourth."

"He won't be sick for long. But he'll need an understanding friend. Will you be that person for him?"

"Well, I mean, you know, I'm willing, I suppose, but it might be better to make some other arrangement, because I'm in a difficult position, financially and all—"

"I wouldn't have asked you if I could think of anything better. It was a blessing that you showed up when you did." She added, "If I hadn't wanted you to find me I would have been much more difficult to find."

"I tried calling, but—"

"I had to discontinue that number." She frowned but didn't offer to explain.

"Well—" Well, fuck, he thought. "I guess I wouldn't turn out a stray dog in a rainstorm."

Her smile returned. "That's what I thought."

"I guess you learned a few things about Fourths since then," Tomas said.

"I don't know," Turk said. "You're the only close sample I've got. Not too inspiring, actually."

"Did she actually say that, about a bullshit detector?"

"More or less. What do you think, Tomas, is it true?"

Tomas had recovered from his illness—from the genetic rebuild that constituted the Fourth treatment—as quickly as Diane had predicted. His psychological adjustment was another matter. He was a man who had come to Equatoria prepared to die, and instead he had found himself staring down another three or more decades for which he had no plan or ambition.

Physically, though, it had been a liberation. After a week of recovery Tomas could have passed for a man much younger. His crabbed way of walking became more supple, his appetite was suddenly bottomless. This was almost too strange for Turk to deal with, as if Tomas had shed his old body the way a snake sheds its skin. "Fuck, it's just me," Tomas would proclaim whenever Turk became too uncomfortably conscious of the distance between the old Tomas and the new. Tomas clearly relished his newfound health. The only drawback, he said, was that the treatment had erased his tattoos. Half his history had been written in those tattoos, he said.

"Is it true that I have an improved bullshit detector? Well, that's in the eye of the beholder. It's been ten years, Turk. What do you think?"

"We never talked much about this."

"I would of been happy to keep it that way."

"Can you tell when you're being lied to?"

"There's no drug that'll make a stupid man smart. And I'm not a particularly smart man. I'm no lie detector, either. But I can generally tell when somebody's trying to sell me something."

"Because I think Lise has been lied to. Her business with Fourths is legitimate, but I think she's being used. Also she has some information Diane might like to hear."

Tomas was silent for a while. He tipped up his beer to drain it and put the bottle on a tray table next to his chair. He gave Turk a look uneasily reminiscent of Diane's evaluative stare.

"You're in some difficult territory here," he said.

"I know that," Turk said.

"Could get dangerous."

"I guess that's what I'm afraid of."

"Can you give me some time to think this over?"

"Guess so," Turk said.

"Okay. I'll ask around. Call me in a couple of days."

"I appreciate it," Turk said. "Thank you."

"Don't thank me yet," Tomas said. "Maybe I'll change my mind."

CHAPTER SEVEN

The node in Lise's car announced new mail as she was driving to the Consulate. "From?" Lise asked.

"Susan Adams," the node replied.

These days Lise could not think of her mother without visualizing that calendar-box of pharmaceuticals on her kitchen counter, assorted by day and hour, the clockwork of her mortality. Pills for depression, pills to adjust her blood cholesterol, pills to avert the Alzheimer's for which she carried a suspect gene. "Read," she said, grimly.

Dear Lise. The node's voice was male, indifferent, offering up the text with all the liveliness of a frozen fish. Thank you for your latest. It is somewhat reassuring after what I've seen on the news.

The ashfall, she meant, which still clogged the side streets and had caused thousands of tourists to flee to their cruise ships, begging for a quick ride home. People who had come to Equatoria hoping to find a landscape pleasingly strange, but who had stumbled into something altogether different—real strangeness, the kind that didn't negotiate with human preconceptions.

Precisely how her mother would have reacted, Lise thought.

All I can think of is how far away you are and how inaccessible you have made yourself. No, I won't start that old argument again. And I won't say a word about your separation from Brian.

Susan Adams had argued fiercely against the divorce—ironically, since she had argued almost as fiercely against the marriage. At first, Lise's mother had disliked Brian because he worked for Genomic Security—Genomic Security, in Susan Adams' mind, being represented by the terse and unhelpful men who had hovered around her after her husband's incomprehensible disappearance. Lise must not marry one of these compassionless monsters, she had insisted; but Brian was not compassionless, in fact Brian had charmed Lise's mother, had patiently dismantled her objections until he became a welcome presence. Brian had quickly learned the paramount rule in dealing with Lise's mother, that one did not mention the New World, the Hypotheticals, the Spin, or the disappearance of Robert Adams. In Susan Adams' household these subjects had acquired the power of profanity. Which was one reason Lise had been so anxious to leave that household behind.

And there had been much anxiety and resistance after the wedding, when Brian was transferred to Port Magellan. You must not go, Lise's mother had said, as if the New World were some ghostly otherness from which no one emerged undamaged. No, not even for the sake of Brian's career should they enter that perdition.

This was, of course, an ongoing act of denial, a forcible exile of unacceptable truths, a strategy her mother had devised for containing and channeling her unvented grief. But that was precisely why Lise resented it. Lise hated the dark space into which her mother had walled these memories. Memory was all that was left of Lise's father, and that memory surely included his wide-eyed fascination with the Hypotheticals and his love of the planet into which they had opened their perplexing doorway.

Even the ashfall would have fascinated him, Lise thought: those cogs and seashells embedded in the dust, pieces in a grand puzzle…

I simply hope that these events convince you of the wisdom of coming home. Lise, if money is a problem, let me book you a ticket. I admit that California is not what it once was, but we can still see the ocean from the kitchen window, and although the summers are warm and the winter storms more intense than I remember them being, surely that's a small thing compared to what you are presently enduring.

You don't know, Lise thought, what I'm enduring. You don't care to know.

In the afternoon sunlight the American Consulate looked like a benevolent fortress set behind a moat of wrought-iron fences. Someone had planted a garden along the runnels of the fence, but the recent ashfall hadn't been kind to the flowers—native flowers, because you weren't supposed to bring terrestrial plants over the Arch, not that the ban was especially effective. The flowers that had survived the ashfall were sturdy red whore's-lips (in the crude taxonomy of the first settlers), stems like enamelled chopsticks and leaves like Victorian collars enfolding the tattered blooms.

There was a guard at the consulate door next to a sign that advised visitors to check all weapons, personal electronics, and unsealed bottles or containers. This was not a new drill for Lise, who had regularly visited Brian at the Genomic Security offices before the divorce. And she remembered riding past the consulate as a teenager during her father's time here; remembered how reassuring and strong the building had seemed with its high white walls and narrow embrasures.

The guard called Brian's office for confirmation and issued her a visitor's badge. She rode the elevator to the fifth floor, mid-building, a tiled windowless hallway, the labyrinth of bureaucracy.

Brian stepped into the corridor as she approached and held open the door marked simply 507 DGS. Brian, she thought, was somehow changeless: carefully dressed, still trim in his mid-thirties, tanned; he took weekend hikes in the hills above the Port. He smiled briefly as a way of greeting her, but his demeanor today was stiff—sort of a whole-body frown, Lise thought. She braced herself for whatever was coming. Brian bossed a staff of three people but none of them was present. "Come on in," he said, "sit down, we have to have a little discussion. I'm sorry, but we'll get this out of the way as quickly as possible."

Even at this juncture he was unfailingly nice, the quality she had found most frustrating in him. The marriage had been bad from the beginning. Not a disaster so much as a bad choice compounded by more bad choices, some of which she was reluctant to admit even to herself. Worse because she couldn't confess her unhappiness in any way Brian was liable to understand. Brian went to church every Sunday, Brian believed in decency and propriety, and Brian despised the complexity and weirdness of the post-Spin world. And that, ultimately, was what Lise could not abide. She had had enough of that from her mother. She wanted, instead, the quality her father had tried so hard to communicate to her on those nights when they looked at the stars: awe, or, failing that, at least courage.

Brian had occasional charm, he had earnestness, he had, buried in him, a deep and poignant seriousness of purpose. But he was afraid of what the world had become, and that, in the end, she could not abide.

She sat down. He pulled a second chair across the carpet and sat facing her knee-to-knee. "This might not be the pleasantest conversation we ever had," he said. "But we're having it for your sake, Lise. Please try to remember that."

Turk arrived at the airport that afternoon still pondering his talk with Tomas and intending to inspect his aircraft before he went home for the night. Turk's little Skyrex twin-engine fixed-wing prop plane was nearly five years old and needed repairs and maintenance more often than it used to. It had lately been fitted with a new fuel injector, and Turk wanted to see for himself what the mechanics had done. So he parked in his usual space behind the cargo building and crossed a patch of tarmac turned woolen-gray by ash and rain, but when he reached the hangar he found the door padlocked. Tucked behind the latch was a note advising him to see Mike Arundji.

Not much question what this was about. Turk owed two months' rent on his hangar space and was in arrears for maintenance.

But he was friendly with Mike Arundji—most of the time, anyhow—and he walked into the owner's office rehearsing his usual excuses. It was a ritual dance: the demand, the apology, the token payment (though even that was going to be tight), another reprieve… although the padlock was a new touch.

This time the older man looked up from his desk with an expression of deep regret. "The lock," he said immediately, "yeah, I'm sorry about that, but I don't have a choice here. I have to run my business like a business."

"It's the ash," Turk said. "I lost a couple of charters to it. Otherwise you'd be paid by now."

"So you say, and I'm not disputing it. But what difference would a couple of charters make, long-term? You have to ask yourself. This isn't the only small airport in the district. I've got competition. In the old days it was okay to be a little loose, cut everybody some slack. It was all semi-amateurs, independents like you. Now there are corporate charter companies bidding up hangar space. Even if the books balanced I'd be taking a loss on you. That's just a fact."

"I can't make money if I can't fly my plane, Mike."

"The trouble is, I can't make money whether you fly it or not."

"Seems like you do okay."

"I have a payroll to meet. I have a whole new raft of regulations coming down from the Provisional Government. If you looked at my spreadsheets you wouldn't tell me I'm doing okay. My accountant doesn't come in here and tell me I'm doing okay."

And you probably don't call your accountant an amateur, Turk thought. Mike Arundji was an old hand: he had opened up this strip when there was nothing south of Port Magellan but fishing villages and squatters' camps. Even a half-dozen years ago the word "spreadsheet" would have been foreign to his vocabulary.

That was the kind of environment in which Turk had arranged for the import—at eye-bulging expense—of his six-seater Skyrex. And it had made him a modest little living, at least until recently. He no longer owed money on it. Unfortunately, he seemed to owe money on everything else. "So what do I have to do to get my plane back in the air?"

Arundji shifted in his chair and wouldn't meet Turk's eye. "Come in tomorrow, we'll talk about it. Worse comes to worst, it wouldn't be hard to find a buyer."

"Find—what?"

"A buyer. A buyer, you know! People are interested. Sell the plane, pay your debts, start fresh. People do that. It happens all the time."

Turk said, "Not to me."

"Calm down. We don't necessarily have conflicting interests here. I can help you get a premium price. I mean, if it comes to that. And shit, Turk, you're the one who's always talking about hiring onto a research boat and sailing somewhere. Maybe this is the time. Who knows?"

"Your confidence is inspiring."

"Think about it, is what I'm saying. Talk to me in the morning."

"I can pay what I owe you."

"Can you? Okay. No problem. Bring me a certified check and we'll forget about it."

To which Turk had no answer.

"Go home," Arundji said. "You look tired, buddy."

"First," Brian said, "I know you were with Turk Findley."

"What the hell?" Lise said promptly.

"Hold on, let me finish—"

"What, you had somebody follow me?"

"I couldn't do that if I wanted to, Lise."

"What, then?"

Brian took a breath. His pursed lips and narrowed eyes were meant to announce that he found this as unpleasant as she did. "Lise, there are other people at work here."

She made an effort to control her own breathing. She was already angry. And in a way the anger was not unwelcome. It beat feeling guilty, the mood in which her encounters usually left her. "What people?"

"Let me just remind you of the larger issues," he said. "Bear with me. It's easy to forget what's at stake. The nature and definition of the human genome, of what we are as a people, all of us. That's been put at risk by everything from the cloning trade to these Martian longevity cults, and there are people in every government in the world who spend a lot of time thinking about that."

His credo, the same justification, Lise recalled, that he had once offered to her mother. "What does that have to do with me?" Or Turk, for that matter.

"You came to me with an old snapshot taken at one of your dad's faculty parties, so I ran it through the database—"

"You offered to run it through the database."

"I offered, okay, and we pulled an image from the dockland security cameras. But when you run a check like that, the query gets bumped around a little bit. And I guess something rang a bell somewhere. Within the last week we've had people from Washington show up here—"

"What do you mean, DGS people?"

"DGS people, right, but very senior, people working out of levels of the department light-years above what we do here. People who are deeply interested in finding the woman in the picture. People interested enough to sail out of Djakarta and knock on my door."

Lise sat back in her chair and tried to absorb all this.

After a long moment she said, "My mother showed the same snapshot to DGS back when my father disappeared. Nobody made a fuss about it then."

"That was a decade ago. Other information has turned up since. The same face in a different context. More than that I can't say."

"I'd like to talk to these people. If they know anything about Sulean Moi—"

"Nothing that would help you find out what happened to your father."

"How can you be sure of that?"

"Try to put it in perspective, Lise. These people are doing an important job. They mean business. I went out of my way to convince these guys not to talk to you."

"But you gave them my name?"

"I told them everything I know about you, because otherwise they might think you're involved in—well, what they're investigating. Which would be a waste of their time and a hardship for you. Honestly, Lise. You have to keep a low profile on this one."

"They're watching me. Is that what you're trying to say? They're watching me and they know I was with Turk."

He winced at the name, but nodded. "They know those things. Yes."

"Jesus, Brian!"

He raised his hands in a gesture that looked like surrender. "All I'm saying is, when I stand back from all this—from what our relationship is and what I would like it to be—when I ask myself what would really be best for you—my advice is to let this go. Stop asking questions. Maybe even think about heading back home, back to California."

"I don't want to go home."

"Think about it, is all I'm saying. There's only so much I can do to protect you."

"I never asked you to protect me."

"Maybe we can talk about this again when you've given it some consideration."

She stood up. "Or maybe not."

"And maybe we can talk about Turk Findley and what's going on in that department."

In that department. Poor Brian, unfailingly prim, even when he was rebuking her.

She thought about defending herself. She could say, We were having dinner when the ash fell. She could say, Of course he came home with me, what was he supposed to do, sleep in his car? She could lie and say, We're just friends. Or she could say, I went to bed with him because he's unafraid and unpredictable and his fingernails aren't impeccably clean and he doesn't work for the fucking DGS.

She was angry, humiliated, not a little guilt-stricken. "It's not your business anymore. You need to figure that out, Brian."

And turned, and left.

Turk went home to fix himself dinner, some shiftless meal appropriate to his mood. He lived in a two-room bungalow set among similar cabins on a barely-paved road near Arundji's airfield, on a bluff overlooking the sea. Maybe someday this would be expensive real estate. Currently it was off-grid. The toilet fed a cesspool and his electricity came from sunlight and a generator in a back shed. Every summer he repaired his shingles, and every winter they leaked from a new angle.

The sun was setting over the foothills west of him, and to the east the sea had turned an inky shade of blue. A few fishing boats straggled toward the harbor to the north. The air was cool and there was a breeze to carry off the remnant stink of the ash.

The ash had settled in windrows around the foundations of the cabin, but the roof seemed to have borne up under the strain. His shelter was intact. There wasn't much food in the kitchen cupboards, however. Less than he remembered. It was canned beans or go out for groceries. Or spend money he didn't have in some restaurant he couldn't afford.

Lost my plane, he thought. But no, not really, not yet; the plane was only embargoed, not yet sold. But there was nothing in his bank account to offer a convincing counter-argument. So that little mantra had been running through his head since he left Mike Arundji's office: Lost my plane.

He wanted to talk to Lise. But he didn't want to dump his problems on her. It still seemed unlikely that he had hooked up with her at all. His relationship with Lise was something fortune had dropped in his lap. Fortune had done him few favors in the past, and he wasn't sure he trusted it.

Cornmeal, coffee, beer…

He decided to give Tomas another call. Maybe he hadn't explained too well what it was he wanted. There was only one real favor he could do Lise, and that was to help her understand why her father had gone Fourth—which Turk assumed was what had happened. And if anyone could explain that to her or put it in a sane perspective it might be Tomas and, if Tomas would put in a word for him, Ibu Diane, the Fourth nurse who lived with the Minang upcoast.

He ticked Tomas's number into his phone.

But there was no answer, nor was the call dumped to voice mail. Which was odd because Tomas carried his phone everywhere. It was probably his most valuable possession.

Turk thought about what to do next. He could go over his accounts and try to rig up some accommodation with Mike Arundji. Or he could drive back into town, maybe see Lise, if she wasn't sick of him—maybe check up on Tomas on the way. The sensible thing, he guessed, would be to stay home and take care of business.

If he had any real business to take care of.

He turned off the lights as he left.

Lise drove away from the consulate feeling scalded. That was the word precisely. Scalded, dipped in hot water, burned raw. She drove aimlessly for more than an hour until the car registered the sunset and switched on its lights. The sky had gone red, one of those long Equatorian sunsets, made gaudier by the fine ash still lingering in the air. She drove through the Arab district, past souks and coffee shops under piebald awnings and strings of colored lights, the crowds dense this evening, making up for time lost during the ashfall; then up into the foothills, the pricey neighborhoods where wealthy men and women from Beijing or Tokyo or London or New York built faux-Mediterranean palaces in pastel shades. Belatedly, she realized she was driving down the street where she had lived with her parents during her four adolescent years in this city.

And here was the house where she had lived when her family was still whole. She slowed the car as she passed. The house was smaller than she remembered and noticeably smaller than the would-be palaces that had grown up around it, a cloth coat among minks. She dreaded to think what it must rent for nowadays. The white-painted veranda was drenched in evening shadow, and had been furnished by strangers.

"This is where we'll be living for the next little while," her mother had told her when they moved here from California. But to Lise it was never "my house," even when she was talking to friends at the American school. It was "where we're staying," her mother's preferred formulation. At thirteen Lise had been a little frightened of the foreign places she had seen on television, and Port Magellan was all those foreign places jumbled together in a single overbrimming gumbo. At least at first, she had longed for lost California.

Now she longed for—what?

Truth. Memory. The extraction of truth from memory.

The roof of the house was dark with ash. Lise could not help picturing herself on the veranda in the old days, sitting with her father. She wished she could sit there with him now, not to discuss Brian or her problems but to speculate about the ashfall, to talk about what Robert Adams had liked to call (inevitably smiling as he said it) the Very Large Subjects, the mysteries that lay beyond the boundary of the respectable world.

It was dark when she finally got home. The apartment was still in disarray, the dishes unwashed in the sink, the bed unmade, a little of Turk's aura still lingering. She poured herself a glass of red wine and tried to think coherently about what Brian had said. About powerful people and their interest in the woman who had (perhaps, in some way) seduced her father away from home.

Was Brian right when he said she should leave? Was there really anything meaningful left to extract from the shards of her father's life?

Or maybe she was closer than she realized to some fundamental truth, and maybe that was why she was in trouble.

Turk guessed there was something wrong when Tomas failed to answer the second and third calls he placed from the car. Tomas might have been drinking—he still drank, though rarely to excess—but even drunk, Tomas usually answered his phone.

So Turk approached the old man's trailer with some apprehension, snaking his car through the dust-choked alleys of the Flats at a cautious speed. Tomas was a Fourth, hence fairly hearty, but not immortal. Even Fourths grew old. Even Fourths died. Tomas might be sick. Or he might be in some other kind of trouble. There was often trouble in the Flats. A couple of Filipino gangs operated out of the area, and there were drug houses scattered through the neighborhood. Unpleasant things happened from time to time.

He parked his car by a noisy bodega and walked the last few yards to the corner of Tomas's muddy little street. It was only just dark and there were plenty of people around, canned music yammering from every other doorway. But Tomas's trailer was dark, the windows unlit. Could be the old man was asleep. But no. The door was unlocked and ajar.

Turk knocked before he stepped inside, even though he had a sour certainty that the gesture was pointless. No answer.

He reached to his left, switched on the overhead light and blinked. The room had been trashed. The table next to Tomas's chair was lying legs-up, the lamp in pieces on the floor. The air still smelled of stale masculine sweat. He made a cursory check of the back bedroom, but it was likewise empty.

After a moment's thought, he left Tomas's small home and knocked at the door of the trailer next door. An obese woman in a gray shift answered: a Mrs. Goudy, lately widowed. Tomas had introduced her to Turk once or twice, and Mrs. Goudy had been known to share a drink with the old man. No, Mrs. Goudy hadn't heard from Tomas lately, but she had noticed a white van parked outside his trailer a little while ago… was anything wrong?

"I hope not. When exactly did you see this van, Mrs. Goudy?"

"Hour ago, maybe two."

"Thank you, Mrs. Goudy. I wouldn't worry about it. Best to keep your door locked, though."

"Don't I know it," Mrs. Goudy said.

He went back to Tomas's place and closed the door, making sure it was secure this time. A wind had come up, and it rattled the makeshift streetlight where Tomas's short walkway met the road. Shadows swayed fitfully.

He took his phone out of his pocket and called Lise, praying she would answer.

Back at the apartment, Lise had her home node read aloud the remainder of her mothers letter. The home unit, at least, had a female voice, slightly if unconvincingly modulated.

Please don't misunderstand, Lise. I'm just worried about you in the usual motherly way. I can't help thinking of you alone in that city—

Alone. Yes. Trust her mother to strike at her vulnerable place. Alone—because it was so hard to make anyone else understand what she wanted here and why it was so important to her.

—putting yourself in danger—

A danger that seemed so much more real when you were, as she said, alone …

—when you could be here at home, safe, or even with Brian, who—

Who would show the same puzzled condescension that radiated from her mothers message.

—would surely agree—

No doubt.

—that there's no use digging up the dead past.

But what if the past wasn't dead? What if she simply lacked the courage or callousness to put the past behind her, had no choice but to pursue it until it yielded its last dividend of pain or satisfaction?

"Pause," she said to the media node. She couldn't take too much of this at one time. Not with everything else that was happening. Not when an alien dust had dropped out of the sky. Not when she was being tracked and possibly bugged by DGS, for reasons not even Brian would explain. Not when she was, yes, thanks Mom for that little reminder, alone.

She checked her other text messages.

They were junk, except for one, which turned out to be gold. It was a note and an attachment sent by one Scott Cleland, whom she had been trying to contact for months. Scott Cleland was the only one of her father's old university associates she hadn't yet succeeded in talking to. He was an astronomer, working with the Geophysical Survey at the observatory on Mt. Mahdi. She had just about given up on him. But here at last was a response to her mail, and a friendly one: the node read it to her, adopting a male voice to suit the given name.

Dear Lise Adams: I'm sorry to have been so slow in responding to your queries. The reason far this is not just procrastination. It took a little searching to find the attached document, which may interest you.

I wasn't close to Dr. Adams but we respected each other's work. As for the details of his life at that time, and the other questions you asked, I'm afraid I can't help you. Our connection was purely professional.

At the time of his disappearance, however, and as you probably know, he had begun work on a book to be called Planet as Artifact. He asked me to read the brief introduction he had written, which I did, but I found no errors and could suggest no significant improvements (apart from a catchier title).

In case there was no copy of this among his papers, I enclose the one he sent me.

Robert Adams' disappearance was a great loss to all of us at the university. He often spoke affectionately about his family, and I hope your research brings you some comfort.

Lise had the household node print the document. Contrary to what Cleland suspected, her father had not left a copy of the introduction with his papers. Or, if he had, Lise's mother had shredded it. Susan Adams had shredded or discarded all of her husband's papers and had donated his books to the university. Part of what Lise had come to think of as the Ritual Cleansing of the Adams Household.

She turned off her phone and poured a glass of wine and took the wine and the six pages of printed text out to the balcony. The night was warm, she had swept away the ash this morning, and the indoor lamps cast enough light to read by.

After a few minutes she went back inside to fetch a pen, came out again and began to underline certain phrases. She underlined them not because they were new to her but because they were familiar.

Many things changed during the interval we call the Spin, but perhaps the most far-reaching change is also the most overlooked. The Earth was held in stasis for more than four billion years, which means we now live in a universe vastly more ancient—and more complexly evolved—than the one to which we were accustomed.

Familiar because, in more polished prose, these were the things he had often said to her when they sat on the veranda and looked out at the darkness and the stars.

Any real understanding of the nature of the Hypotheticals must take this into account. They were ancient when we first encountered them, and they are more ancient now. Since they cannot be observed directly, we must make our deductions about them based on their work in the universe, by the clues they leave behind them, by their vast and abiding footprints.

Here was the excitement she learned from him at an early age, an outward-looking curiosity that contrasted with her mother's habitual caution and timidity. She could hear his voice in the words.

Of their works, one of the most immediately obvious is the Indian Ocean Arch that links the Earth to the New World—and the Arch that connects the New World to another less hospitable planet, and so on, as far as we have been able to explore: a chain of increasingly hostile environments made available to us for reasons we do not yet understand.

Sail to the other side of this world, he had told Lise, and you'll find a second Arch, and beyond it a rocky, stormy planet with barely breathable air; and beyond that—a journey that had to be undertaken on ocean vessels sealed and pressurized as if they were spaceships—a third world, its atmosphere poisoned with methane, the oceans oily and acidic.

But the Arch is not the only artifact at hand. The planet "next door to Earth," from which I write these words, is also an artifact. There is evidence that it was constructed or at least modified over the course of many millions of years with the objective of making it a congenial environment for human beings.

Planet as artifact.

Many have speculated about the purpose of this eons-long work. Is the New World a gift or is it a trap? Have we entered a maze, as laboratory mice, or have we been offered a new and splendid destiny? Does the fact that our own Earth is still protected from the deadly radiation of its expanded sun mean that the Hypotheticals take an interest in our survival as a species, and if so, why?

I cannot claim to have answered any of these questions, but I mean to give the reader an overview of the work that has already been done and of the thoughts and speculations oj the men and women who are devoting their professional lives to that work…

And, later in the piece, this:

We are in the position of a coma patient waking from a sleep as long as the lifetime of a star. What we cannot remember, we must rediscover.

She underlined that twice. She wished she could text it to her mother, wished she could write it on a banner and wave it in Brian's face. This was all she had ever meant to say to them: an answer to their genteel silences, to the almost surgical elision of Robert Adams from the lives of his survivors, to the gently troubled poor-Lise expressions they wore on their faces whenever she insisted on mentioning her vanished father. It was as if Robert Adams himself had stepped out of obscurity to whisper a reassuring word. What we cannot remember, we must rediscover.

She had put the pages aside and was heading for bed when she checked her phone one last time.

Three messages were stacked there, all tagged urgent, all from Turk. A fourth came in while the phone was still in her hand.
