The stacks of books, paper, and fountain pens were not there, and their names had been removed from the plaque at the front of the room. "It's a lovely spring day," Miss Matheson said. "Let's gather some foxgloves."

They went across the playing fields to the meadow where the wildflowers grew, the two girls walking and Miss Matheson's wheelchair carrying her along on its many-spoked smart wheels.

"Chiselled Spam," Miss Matheson said, sort of mumbling it to herself.

"Pardon me, Miss Matheson?" Nell said.

"I was just watching the smart wheels and remembering an advertisement from my youth," Miss Matheson said. "I used to be a thrasher, you know. I used to ride skateboards through the streets. Now I'm still on wheels, but a different kind. Got a few too many bumps and bruises during my earlier career, I'm afraid."

. . .

"It's a wonderful thing to be clever, and you should never think otherwise, and you should never stop being that way. But what you learn, as you get older, is that there are a few billion other people in the world all trying to be clever at the same time, and whatever you do with your life will certainly be lost-swallowed up in the ocean-unless you are doing it along with like-minded people who will remember your contributions and carry them forward. That is why the world is divided into tribes. There are many Lesser phyles and three Great ones. "What are the Great ones?"

"New Atlantis," Nell began.

"Nippon," said Fiona.

"Han," they concluded together.

"That is correct," Miss Matheson said. "We traditionally include Han in the list because of its immense size and age-even though it has lately been crippled by intestine discord. And some would include Hindustan, while others would view it as a riotously diverse collection of microtribes sintered together according to some formula we don't get.

"Now, there was a time when we believed that what a human mind could accomplish was determined by genetic factors. Piffle, of course, but it looked convincing for many years, because distinctions between tribes were so evident. Now we understand that it's all cultural. That, after all, is what a culture is-a group of people who share in common certain acquired traits.

"Information technology has freed cultures from the necessity of owning particular bits of land in order to propagate; now we can live anywhere. The Common Economic Protocol specifies how this is to be arranged.

"Some cultures are prosperous; some are not. Some value rational discourse and the scientific method; some do not. Some encourage freedom of expression, and some discourage it. The only thing they have in common is that if they do not propagate, they will be swallowed up by others. All they have built up will be torn down; all they have accomplished will be forgotten; all they have learned and written will be scattered to the wind. In the old days it was easy to remember this because of the constant necessity of border defence. Nowadays, it is all too easily forgotten.

"New Atlantis, like many tribes, propagates itself largely through education. That is the raison d'

"What is the point of Miss Stricken's class? Anyone? Please speak up. You can't get in trouble, no matter what you say."

Nell said, after some dithering, "I'm not sure that it has any point." Fiona just watched her saying it and smiled sadly.

Miss Matheson smiled. "You are not far off the mark. Miss Stricken's phase of the curriculum comes perilously close to being without any real substance. Why do we bother with it, then?"

"I can't imagine," Nell said.

"When I was a child, I took a karate class," Miss Matheson said, astonishingly. "Dropped out after a few weeks. Couldn't stand it. I thought that the sensei would teach me how to defend myself when I was out on my skateboard. But the first thing he did was have me sweep the floor. Then he told me that if I wanted to defend myself, I should buy a gun. I came back the next week and he had me sweep the floor again. All I ever did was sweep. Now, what was the point of that?"

"To teach you humility and self-discipline," Nell said. She had learned this from Dojo long ago.

"Precisely. Which are moral qualities. It is upon moral qualities that a society is ultimately founded. All the prosperity and technological sophistication in the world is of no use without that foundation-we learned this in the late twentieth century, when it became unfashionable to teach these things."

"But how can you say it's moral?" said Fiona. "Miss Stricken isn't moral. She's so cruel."

"Miss Stricken is not someone I would invite to dinner at my house. I would not hire her as a governess for my children. Her methods are not my methods. But people like her are indispensable.

"It is the hardest thing in the world to make educated Westerners pull together," Miss Matheson went on. "That is the job of people like Miss Stricken. We must forgive them their imperfections. She is like an avatar-do you children know about avatars? She is the physical embodiment of a principle. That principle is that outside the comfortable and welldefended borders of our phyle is a hard world that will come and hurt us if we are not careful. It is not an easy job to have. We must all feel sorry for Miss Stricken."

They brought sheaves of foxgloves, violet and magenta, back to the school and set them in vases in each classroom, leaving an especially large bouquet in Miss Stricken's office. Then they took tea with Miss Matheson, and then they each went home.

Nell could not bring herself to agree with what Miss Matheson had said; but she found that, after this conversation, everything became easy. She had the neo-Victorians all figured out now. The society had miraculously transmutated into an orderly system, like the simple computers they programmed in the school. Now that Nell knew all of the rules, she could make it do anything she wanted.

"Joy" returned to its former position as a minor annoyance on the fringes of a wonderful schoolday. Miss Stricken got her with the ruler from time to time, but not nearly so often, even when she was, in fact, scratching or slumping.

Fiona Hackworth had a harder time of it, and within a couple of months she was back on the Supplementary Curriculum list. A few months after that, she stopped coming to school entirely. It was announced that she and her mother had moved to Atlantis/Seattle, and her address was posted in the hall for those who wished to write her letters.

But Nell heard rumors about Fiona from the other girls, who had picked up snatches from their parents. After Fiona had been gone for a year or so, word got out that Fiona's mother had obtained a divorce— which, in their tribe, only happened in cases of adultery or abuse. Nell wrote Fiona a long letter saying she was terribly sorry if her father had been abusive, and offering her support in that case. A few days later she got back a curt note in which Fiona defended her father from all charges. Nell wrote back a letter of apology but didn't hear from Fiona Hackworth again.

It was about two years later that the news feeds filled up with astonishing tales of the young heiress Elizabeth Finkle-McGraw, who had vanished from her family's estate outside of London and was rumored to have been sighted in London, Los Angeles, Hong Kong, Miami, and many other places, in the presence of people suspected of being highranking members of CryptNet.

Hackworth awakes from a dream;

retreat from the world of the Drummers;

chronological discrepancies.

Hackworth woke from a dream of unsustainable pleasure and realized it wasn't a dream; his penis was inside someone else, and he was steaming like a runaway locomotive toward ejaculation. He had no idea what was going on; but couldn't he be forgiven for doing the wrong thing? With a wiggle here and a thrust there, he finally nudged himself over the threshold, the smooth muscles of the tract in question executing their spinal algorithm.

Just a few deep breaths into the refractory period, and he had already disengaged, yelping a little from the electric spark of withdrawal, and levered himself up on one arm to see whom he'd just violated. The firelight was enough to tell him what he already knew: Whoever this woman was, it wasn't Gwen. Hackworth had violated the most important promise he'd ever made, and he didn't even know the other party.

But he knew it wasn't the first time. Far from it. He'd had sex with a lot of people in the past few years— he'd even been buggered.

There was, for example, the woman-

Never mind, there was the man who-

Strange to say, he could not think of any specific examples. But he knew he was guilty. It was precisely like waking up from a dream and having a clear train of thought in your mind, something you were working on just a few seconds ago, but being unable to remember it, consciousness peeled away from cognition. Like a three-year-old who has a talent for vanishing into crowds whenever you turn your back, Hackworth's memories had fled to the same place as words that are on the tip of your tongue, precedents for d

He knew he was in big trouble with Gwen, but that Fiona still loved him— Fiona, taller than Gwen now, so self-conscious about her still linear figure, still devoid of the second derivatives that add spice to life.

Taller than Gwen? How's that?

Better get out of this place before he had sex with someone else he didn't know.

He wasn't in the central chamber anymore, rather in one of the tunnel's aneurysms with some twenty other people, all just as naked as he was. He knew which tunnel led to the exit (why?) and began to crawl down it, rather stiffly as it seemed that he was stiff and laden with cricks and cramps. Must not have been very athletic sex— more in the Tantric mode.

Sometimes they had sex for days.

How did he know that?

The hallucinations were gone, which was fine with him. He crawled through the tunnels for a long time. If he tried to think about where he was going, he got lost and eventually circled back to where he started. Only when his mind began to wander did he make his way on some kind of autopilot to a long chamber filled with silvery light, sloping upward. This was beginning to look familiar, he had seen this when he was still a young man. He followed it upward until he reached the end, where something unusually stony was under his feet. A hatch opened above him, and several tons of cold seawater landed on his head.

He staggered up onto dry land and found himself in Stanley Park again, gray floor aft, green wall fore. The ferns rustled, and out stepped Kidnapper, who looked fuzzy and green. He also looked unusually dapper for a robotic horse, as Hackworth's bowler hat was perched on top of his head.

Hackworth reached up to feel himself and was astounded to feel his face covered with hair. Several months' growth of beard was there. But even stranger, his chest was much hairier than it had been before. Some of the chest hair was gray, the only gray hairs he had ever seen coming out of his own follicles.

Kidnapper was fuzzy and green because moss had been growing on him. The bowler looked terrible and had moss on it too. Hackworth reached out instinctively and put it on his head. His arm was thicker and hairier than it used to be, a not altogether unpleasing change, and even the hat felt a little tight.

From the Primer, Princess Nell crosses the trail of the enigmatic Mouse Army;

a visit to an invalid.

The clearing dimly visible through the trees ahead was a welcome sight, for the forests of King Coyote were surpassingly deep and forever shrouded in cool mists. Fingers of sunlight had begun to thrust between the clouds, and so Princess Nell decided to rest in the open space and, with any luck, bask in the sunlight. But when she reached the clearing, she found that it was not the flowerstrewn greensward she had expected; it was rather a swath that had been carved through the forest by the passage of some titanic force, which had flattened trees and churned up the soil as it progressed. When Princess Nell had recovered from her astonishment and mastered her fear, she resolved to make use of the tracking skills she had learned during her many adventures, so as to learn something about the nature of this unknown creature.

As she soon discovered, the skills of an advanced tracker were not necessary in this case. The merest glance at the trampled soil revealed not (as she had anticipated) a few enormous footprints, but millions of tiny ones, superimposed upon one another in such numbers that no scrap of ground was unmarked by the impressions of tiny claws and footpads.

A torrent of cats had passed this way; even had Princess Nell not recognized the footprints, the balls of loose hair and tiny scats, strewn everywhere, would have told the story. Cats moving in a herd! It was most unfeline behavior. Nell followed their track for some time, hoping to divine the cause of this prodigy. After a few miles the road widened into an abandoned camp freckled with the remains of innumerable small campfires. Nell combed this area for more clues, not without success: she found many mouse droppings here, and mouse footprints around the fires. The pattern of footprints made it clear that the cats had been concentrated in a few small areas, while the mice had apparently had the run of the place.

The final piece of the puzzle was a tiny scrap of twisted rawhide that Nell found abandoned near one of the little campfires. Turning it around in her fingers, Nell realized that it was much like a horse's bridle— except sized to fit around the head of a cat.

She was standing on the trail of a vast army of mice, who rode on the backs of cats in the way that knights ride on horses.

She had heard tales of the Mouse Army in other parts of the Land Beyond and dismissed them as ancient superstitions.

But once, several years ago, in an inn high in the mountains, where Princess Nell had stayed for the night, she had been awakened early in the morning by the sound of a mouse rooting through her pack. .

Princess Nell uttered a light-making spell that Purple had taught her, kindling a ball of luminance that hung in the air in the center of the room. The words of the spell had been concealed in the howl of the mountain winds through the rickety structure of the old inn, and so the mouse was caught entirely by surprise, blinded by the sudden light. Nell was startled to see that the mouse was not gnawing its way into her supply of food, as any mouse should have done, but rather was going through some of her papers. And this was not the usual destructive search for nesting material-this mouse knew how to read and was looking for information. Princess Nell trapped the mouse spy under her hands.

"What are you looking for? Tell me, and I shall let you escape!" she said. Her adventures had taught her to be on the lookout for tricks of all kinds, and it was important that she learn who had dispatched this tiny, but effective, spy.

"I am but a harmless mouse!" the spy squealed. "I do not even desire your food— information only!"

"I will give you a big piece of cheese, all to yourself, if you give me some information," Princess Nell said. She caught the mouse's tail and lifted him up into the air so that they could talk face-to-face. Meanwhile, with her other hand, she loosened the drawstring of her bag and drew out a nice piece of blue-veined Stilton.

"We are seeking our lost Queen," the mouse said.

"I can assure you that none of my papers have any information about a missing mouse monarch," Princess Nell said.

"What is your name?" the mouse said.

"That is none of your business, spy!" Princess Nell said. "I will ask the questions."

"But it is very important that I know your name," the mouse said.

"Why? I am not a mouse. I have not seen any little mice with crowns on their heads."

The mouse spy said nothing. He was staring carefully at Princess Nell with his little beady eyes. "Did you, by any chance, come from an enchanted island?"

"You have been listening to too many fairy tales," Princess Nell said, barely concealing her astonishment. "You have been most uncooperative and so do not deserve any cheese— but I admire your pluck and so will give you some anyway. Enjoy yourself!" She set the mouse down on the floor and took out her knife to cut off a bit of the cheese; but by the time she was finished, the mouse had disappeared. She just caught sight of his pink tail disappearing under the door.

The next morning, she found him dead on the hallway floor. The innkeeper's cat had caught him. .

So the Mouse Army did exist! Princess Nell wondered whether they had ever located their lost Queen. She followed their trail for another day or two, as it went in approximately the right direction and was almost as convenient as a road.

She passed through a few more campsites. At one of them, she even found a little gravesite, marked with a tiny headstone carved from a chip of soapstone.

The carvings on this tiny monument were much too small to see. But Princess Nell carried with her a magnifying glass that she had pilfered from the treasury of one of the Faery Kings, and so now she removed it from its padded box and its velvet bag and used it to examine the inscription.

At the top of the stone was a little bas-relief of a mouse knight, dressed in armor, with a sword in one hand, bowing before an empty throne. The inscription read,

Here lies Clover, tail and all

Her virtues far outweighed her flaws

She from the saddle took a fall

And perished 'neath her charger's paws.

We know not if her final ride

Hath led her into Heaven or Hell

Wherever she doth now abide

She's loyal yet to Princess Nell.

Princess Nell examined the remains of the fires, and the surfaces of the wood that the Mouse Army had cut, and the state of their droppings, and estimated that they had passed by here many weeks previously. One day she would rendezvous with them and find out why they had formed such an attachment to her; but for now, she had more pressing considerations.

. . .

She'd have to see about the Mouse Army later. Today was Saturday, and on Saturday morning she always went down to the Leased Territories to visit her brother. She opened up the wardrobe in the corner of her sleeping room and took out her traveling dress. Sensing her intentions, the chaperone flew out of its niche in the back and whined over to the door.

Even at her still-tender age, just a few years past the threshold of womanhood, Nell had already had cause to be grateful for the presence of the droning chaperone pod that followed her everywhere when she ventured from home alone. Maturity had given her any number of features that would draw the attention of the opposite sex, and of women so inclined. Commentators rarely failed to mention her eyes, which were said to have a vaguely exotic appearance. There was nothing particularly unusual about their shape or size, and their color-a tweedy blend of green and light brown flecked with gold-did not make them stand out in a predominantly Anglo-Saxon culture. But Nell's eyes had an appearance of feral alertness that seized the attention of anyone who met her. Neo-Victorian society produced many young women who, though highly educated and well-read, were still blank slates at Nell's age. But Nell's eyes told a different story. When she had been presented to society a few months ago, along with several other External Propagation girls at Miss Matheson's Academy, she had not been the prettiest girl at the dance, and certainly not the best dressed or most socially prominent. She had attracted a crowd of young men anyway. They did not do anything so obvious as mill around her; instead they tried to keep the distance between themselves and Nell below a certain maximum, so that wherever she went in the ballroom, the local density of young men in her area became unusually high.

In particular she had excited the interest of a boy who was the nephew of an Equity Lord in Atlantis/Toronto. He had written her several ardent letters. She had responded saying that she did not wish to continue the relationship, and he had, perhaps with the help of a hidden monitor, encountered her and her chaperone pod one morning as she had been riding to Miss Matheson's Academy. She had reminded him of the recent termination of their relationship by declining to recognize him, but he had persisted anyway, and by the time she had reached the gates of the Academy, the chaperone pod had gathered enough evidence to support a formal sexual harassment accusation should Nell have wished to bring one.

Of course she did not, because this would have created a cloud of opprobrium that would have blighted the young man's career. Instead, she excerpted one five-second piece of the cine record from the chaperone pod: the one in which, approached by the young man, Nell said, "I'm sorry, but I'm afraid you have me at a disadvantage," and the young man, failing to appreciate the ramifications, pressed on as if he had not heard. Nell placed this information into a smart visiting card and arranged to have it dropped by the young man's family home. A formal apology was not long in coming, and she did not hear again from the young man.

Now that she had been introduced to society, her preparations for a visit to the Leased Territories were just as elaborate as for any New Atlantis lady. Outside of New Atlantis, she and her chevaline were surrounded everywhere by a shell of hovering security pods serving as a first line of personal defense. A modern lady's chevaline was designed with a sort of Y-shaped body that made it unnecessary to ride sidesaddle, so Nell was able to wear a fairly normal-looking sort of dress: a bodice that took advantage of her fashionably narrow waist, so carefully honed on the Academy's exercise machines that it might have been turned on a lathe from walnut. Beyond that, her skirts, sleeves, collar, and hat saw to it that none of the young ruffians of the Leased Territories would have the opportunity to invade her body space with their eyes, and lest her distinctive face prove too much of a temptation, she wore a veil too.

The veil was a field of microscopic, umbrellalike aerostats programmed to fly in a sheet formation a few inches in front of Nell's face. The umbrellas were all pointed away from her. Normally they were furled, which made them nearly invisible; they looked like the merest shadow before her face, though viewed sideways they created a subtle wall of shimmer in the air. At a command from Nell they would open to some degree. When fully open, they nearly touched each other. The outside-facing surfaces were reflective, the inner ones matte black, so Nell could see out as if she were looking through a piece of smoked glass. But others saw only the shimmering veil. The umbrellas could be programmed to dangle in different ways-always maintaining the same collective shape, like a fencing mask, or rippling like a sheet of fine silk, depending on the current mode.

The veil offered Nell protection from unwanted scrutiny. Many New Atlantis career women also used the veil as a way of meeting the world on their own terms, ensuring that they were judged on their own merits and not on their appearance. It served a protective function as well, bouncing back the harmful rays of the sun and intercepting many deleterious nanosites that might otherwise slip unhindered into the nose and mouth.

The latter function was of particular concern to Constable Moore on this morning. "It's been nasty of late," he said. "The fighting has been very bad." Nell had already inferred this from certain peculiarities of the Constable's behavior: he had been staying up late at night recently, managing some complicated enterprise spread out across his mediatronic floor, and she suspected that it was something along the lines of a battle or even a war.

As she rode her chevaline across Dovetail, she came to a height-of-land that afforded a fine view across the Leased Territories, Pudong, and Shanghai on a clear day. But the humidity had congealed into drifts of clouds forming a seamless layer about a thousand feet below their level, so that this high territory at the top of New Chusan seemed to be an island, the only land in all the world except for the snowcapped cone of the Nippon Clave a few miles up the coast.

She departed through the main gate and rode down the hill. She kept approaching the cloud layer but never quite reached it; the lower she went, the softer the light became, and after a few minutes she could no longer see the rambling settlements of Dovetail when she turned around, nor the spires of St. Mark's and Source Victoria above it. After another few minutes' descent the fog became so thick that she could not see more than a few meters, and she smelled the elemental reek of the ocean. She passed the former site of the Sendero Clave. The Senderos had been bloodily uprooted when Protocol Enforcement figured out that they were working in concert with the New Taiping Rebels, a fanatical cult opposed to both the Fists and the Coastal Republic. This patch of real estate had since passed into the hands of the Dong, an ethnic minority tribe from southwestern China, driven out of their homeland by the civil war. They had torn down the high wall and thrown up one of their distinctive many-layered pagodas.

Other than that, the L.T. didn't look all that different. The operators of the big wall-size mediatrons that had so terrified Nell on her first night in the Leased Territories had turned the brightness all the way up, trying to compensate for the fog.

Down by the waterfront, not far from the Aerodrome, the compilers of New Chusan had, as a charitable gesture, made some space available to the Vatican. In the early years it had contained nothing more than a twostory mission for thetes who had followed their lifestyle to its logical conclusion and found themselves homeless, addicted, hounded by debtors, or on the run from the law or abusive members of their own families.

More recently those had become secondary functions, and the Vatican had programmed the building's foundation to extrude many more stories. The Vatican had a number of serious ethical concerns about nanotech but had eventually decided that it was okay as long as it didn't mess about with DNA or create direct interfaces with the human brain. Using nanotech to extrude buildings was fine, and that was fortunate, because Vatican/Shanghai needed to add a couple of floors to the Free Phthisis Sanatorium every year. Now it loomed high above any of the other waterfront buildings.

As with any other extruded building, the design was drab in the extreme, each floor exactly alike. The walls were of an unexceptional beige material that had been used to construct many of the buildings in the L.T., which was unfortunate, because it had an almost magnetic attraction for the cineritious corpses of airborne mites. Like all the other buildings so constituted, the Free Phthisis Sanatorium had, over the years, turned black, and not evenly but in vertical rain-streaks. It was a clich

Harv was lying on the top of a three-layer bunkbed on the twentieth floor, sharing a small room and a supply of purified air with a dozen other chronic asthma sufferers. His face was goggled into a phantascope, and his lips were wrapped around a thick tube plugged into a nebulizer socket on the wall. Vaporized drugs, straight from the matter compiler, were flowing down that tube and into his lungs, working to keep his bronchi from spasming shut.

Nell stopped for a moment before breaking him out of his ractive. Some weeks he looked better than others; this week he did not look good. His body was bloated, his face round and heavy, his fingers swollen to puffy cylinders; they had been giving him heavy steroid treatments. But she would have known he'd had a bad week anyway, because usually Harv didn't go in for immersive ractives. He liked the kind you held in your lap on a sheet of smart paper.

Nell tried to send Harv a letter every day, simply written in mediaglyphics, and for a while he had tried to respond in kind. Last year he had even given up on this, though she wrote him faithfully anyway.

"Nell!" he said when he had peeled the goggles away from his eyes. "Sorry, I was chasing some rich Vickys."

"You were?"

"Yeah. Or Burly Scudd was, I mean. In the ractive. See, Burly's bitch gets pregnant, and she's got to buy herself a Freedom Machine to get rid of it, so she gets a job as a maid-of-all-work for some snotty Vickys and rips off some of their nice old stuff, figuring that's a faster way to get the money. So the bitch is running away and they're chasing her on their chevs, and then Burly Scudd shows up in his big truck and turns the tables and starts chasing them. If you do it right, you can get the Vickys to fall into a big pit of manure! It's great! You should try it," Harv said, then, exhausted by this effort, grabbed his oxygen tube and pulled on it for a while.

"It sounds entertaining," Nell said.

Harv, temporarily gagged by the oxygen tube, watched her face carefully and was not convinced. "Sorry," he blurted between breaths, "forgot you don't care for my kind of ractive. Don't they have Burly Scudd in that Primer of yours?"

Nell made herself smile at the joke, which Harv had been making every week. She handed him the basket of cookies and fresh fruit that she had brought down from Dovetail and sat with him for an hour, talking about the things he enjoyed talking about, until she could see his attention wandering back toward the goggles. Then she said good-bye until next week and kissed him good-bye.

She turned her veil to its highest level of opacity and made her way toward the door. Harv impulsively grabbed his oxygen tube and sucked on it mightily a few times, then called her name just as she was about to leave.

"Yes?" she said, turning toward him.

"Nell, I want to tell you how fine you look," he said, "just like the finest Vicky lady in all of Atlantis. I can't believe you're my same Nell that I used to bring things to in the old flat-remember those days? I know that you and I have gone different ways, ever since that morning in Dovetail, and I know it's got a lot to do with that Primer. I just want to tell you, sister, that even though I say bad stuff about Vickys sometimes, I'm as proud of you as I could be, and I hope when you read that Primer-so full of stuff I could never understand or even read-you'll think back on your brother Harv, who saw it lying in the gutter years ago and took it into -his mind to bring it to his kid sister. Will you remember that, Nell?" With that he plugged the oxygen tube back into his mouth, and his ribs began to heave.

"Of course I will, Harv," Nell said, her eyes filling with tears, and blundered her way back across the room until she could sweep Harv's bloated body up in her strong arms. The veil swirled like a sheet of water thrown into Harv's face, all the little umbrellas drawing themselves out of the way as she brought his face up to hers and planted a kiss on his cheek.

The veil congealed again as he sank back down onto the foam mattress— just like the mattresses he had taught her to get from the M.C., long ago-and she turned and ran out of the room sobbing.

Hackworth is brought up-to-date by the great Napier.

"Have you had the opportunity to speak with your family?" Colonel Napier said, speaking out of a mediatronic tabletop from his office in Atlantis/Shanghai. Hackworth was sitting in a pub in Atlantis/Vancouver.

Napier looked good now that he was deeper into middle age— somewhat more imposing. He'd been working on his bearing.

Hackworth had been temporarily impressed when Napier's image had first materialized on the mediatron, then he remembered his own image in the mirror. Once he'd gotten himself cleaned up and trimmed his beard, which he'd decided to keep, he realized that he had a new bearing of his own. Even if he was desperately confused about how he got it.

"Thought I'd find out what the hell happened first. Besides-" He stopped talking for a while. He was having trouble getting his conversational rhythm back.

"Yes?" Napier said in a labored display of patience.

"I just spoke to Fiona this morning."

"After you left the tunnels?"

"No. Before. Before I-woke up, or whatever."

Napier was slightly taken aback and only popped his jaw muscles a couple of times, reached for his tea, looked irrelevantly out the window at whatever view he had out his office window in New Chusan. Hackworth, on the other side of the Pacific, contented himself with staring into the inky depths of a pint of stout.

A dream-image surfaced in Hackworth's mind, like a piece of debris rising to the surface after a shipwreck, inexorably muscling tons of green murk out of its path. He saw a glistening blue projectile shoot into the Doctor's beige-gloved hands, trailing a thick cord, watched it unfold, nay bloom into a baby.

"Why did I think of that?" he said.

Napier seemed puzzled by this remark. "Fiona and Gwendolyn are in Atlantis/Seattle now-half an hour from your present location by tube," he said.

"Of course! They live— we live— in Seattle now. I knew that." He was remembering Fiona hiking around in the caldera of some snow-covered volcano.

"If you are under the impression that you've been in contact with her recently-which is quite out of the question, I'm afraid— then it must have been mediated through the Primer. We were not able to break the encryption on the signals passing out of the Drummers' cave, but traffic analysis suggests that you've spent a lot of time racting in the last ten years."

"Ten years!?"

"Yes. But surely you must have suspected that, from evidence."

"It feels like ten years. I sense that ten years of things have happened to me. But the engineer hemisphere has a bit of trouble coming to grips."

"We are at a loss to understand why Dr. X would choose to have you serve out your sentence among the Drummers," Napier said. "It would seem to us that your engineer hemisphere, as you put it, is your most desirable feature as far as he is concerned-you know that the Celestials are still terribly short of engineers."

"I've been working on something," Hackworth said. Images of a nanotechnological system, something admirably compact and elegant, were flashing over his mind's eye. It seemed to be very nice work, the kind of thing he could produce only when he was concentrating very hard for a long time. As, for example, a prisoner might do.

"What sort of thing exactly?" Napier asked, suddenly sounding rather tense.

"Can't get a grip on it," Hackworth finally said, shaking his head helplessly. The detailed images of atoms and bonds had been replaced, in his mind's eye, by a fat brown seed hanging in space, like something in a Magritte painting. A lush bifurcated curve on one end, like buttocks, converging to a nipplelike point on the other.

"What the hell happened?"

"Before you left Shanghai, Dr. X hooked you up to a matter compiler, no?"

"Yes."

"Did he tell you what he was putting into your system?"

"I guessed it was h

"We took blood samples before you left Shanghai."

"You did?"

"We have ways," Colonel Napier said. "We also did a full workup on one of your friends from the cave and found several million nanosites in her brain."

"Several million?"

"Very small ones," Napier said reassuringly. "They are introduced through the blood, of course-the h

"So when I was on my own, my 'sites just talked to themselves," Hackworth said, "but when I came into close proximity with other people who had these things in their brains-"

"It didn't matter which brain a 'site was in. They all talked to one another indiscriminately, forming a network. Get some Drummers together in a dark room, and they become a gestalt society."

"But the interface between these nanosites and the brain itself-"

"Yes, I admit that a few million of these things piggybacking on randomly chosen neurons is only a feeble interface to something as complicated as the human brain," Napier said. "We're not claiming that you shared one brain with these people."

"So what did I share with them exactly?" Hackworth said.

"Food. Air. Companionship. Body fluids. Perhaps emotions or general emotional states. Probably more."

"That's all I did for ten years?"

"You did a lot of things," Napier said, "but you did them in a sort of unconscious, dreamlike state. You were sleepwalking. When we figured that out-after doing the biopsy on your fellow-troglodyte— we realised that in some sense you were no longer acting of your own free will, and we engineered a hunter-killer that would seek out and destroy the nanosites in your brain. We introduced it, in a dormant mode, into this female Drummer's system, then reintroduced her to your colony. When you had sex with her-well, you can work out the rest for yourself."

"You have given me information, Colonel Napier, and I am grateful, but it has only made me more confused. What do you suppose the Celestial Kingdom wanted with me?"

"Did Dr. X ask anything of you?"

"To seek the Alchemist."

Colonel Napier looked startled. "He asked that of you ten years ago?"

"Yes. In as many words."

"That is very singular," Napier said, after a prolonged interlude of mustache-twiddling. "We have only been aware of this shadowy figure for some five years and know virtually nothing about him— other than that he is a wizardly artifex who is conspiring with Dr. X."

"Is there any other information-"

"Nothing that I can reveal," Napier said brusquely, perhaps having revealed too much already. "Do let us know if you find him, though. Er, Hackworth, there is no tactful way to broach this subject. Are you aware that your wife has divorced you?"

"Oh, yes," Hackworth said quietly. "I suppose I did know that." But he hadn't been conscious of it until now.

"She was remarkably understanding about your long absence," Napier said, "but at some point it became evident that, like all the Drummers, you had become sexually promiscuous in the extreme."

"How did she know?"

"We warned her."

"Pardon me?"

"I mentioned earlier that we found things in your blood. These h

"How do you know that?"

Napier seemed impatient for the first time. "For god's sake, man, we know what we are doing. These particles had two functions: spread through exchange of bodily fluids, and interact with each other. Once we saw that, we had no ethical choice but to inform your wife."

"Of course. That's only right. As a matter of fact, I thank you for it," Hackworth said. "And it's not hard to understand Gwen's feelings about sharing bodily fluids with thousands of Drummers."

"You shouldn't beat yourself up," Napier said. "We've sent explorers down there."

"Really?"

"Yes. The Drummers don't mind. The explorers relate that the Drummers behave much the way people do in dreams. 'Poorly defined ego boundaries' was the phrase, as I recall. In any event, your behaviour down there wasn't necessarily a moral transgression as such-your mind wasn't your own."

"You said that these particles interact with each other?"

"Each one is a container for some rod logic and some memory," Napier said. "When one particle encounters another either in vivo or in vitro, they dock and seem to exchange data for a few moments. Most of the time they disengage and drift apart. Sometimes they stay docked for a while, and computation takes place-we can tell because the rod logic throws off heat. Then they disconnect. Sometimes both particles go their separate ways, sometimes one of them goes dead. But one of them always keeps going."

The implications of that last sentence were not lost on Hackworth. "Do the Drummers only have sex with one another, or-"

"That was our first question too," Napier said. "The answer is no. They have a very good deal of sex with many, many other people. They actually run bordellos in Vancouver. They cater especially to the Aerodrome-and-tube-station crowd. A few years ago they came into conflict with the established bordellos because they were hardly charging any money at all for their services. They raised their prices just to be diplomatic. But they don't want the money— what on earth would they do with it?"

From the Primer, a visit to Castle Turing;

a final chat with Miss Matheson;

speculation as to Nell's destiny;

farewell;

conversation with a grizzled hoplite;

Nell goes forth to seek her fortune.

The new territory into which Princess Nell had crossed was by far the largest and most complex of all the Faery Kingdoms in the Primer. Paging back to the first panoramic illustration, she counted seven major castles perched on the mountaintops, and she knew perfectly well that she would have to visit all of them, and do something difficult in each one, in order to retrieve the eleven keys that had been stolen from her and the one key that remained.

She made herself some tea and sandwiches and carried them in a basket to a meadow, where she liked to sit among the wildflowers and read. Constable Moore's house was a melancholy place without the Constable in it, and it had been several weeks since she had seen him. During the last two years he had been called away on business with increasing frequency, vanishing (as she supposed) into the interior of China for days, then weeks at a time, coming back depressed and exhausted to find solace in whiskey, which he consumed in surprisingly moderate quantities but with fierce concentration, and in midnight bagpipe recitals that woke up everyone in Dovetail and a few sensitive sleepers in the New Atlantis Clave.

During her trip from the campsite of the Mouse Army to the first of the castles, Nell had to use all the wilderness skills she had learned in years of traveling around the Land Beyond: She fought with a mountain lion, avoided a bear, forded streams, lit fires, built shelters. By the time Nell had maneuvered Princess Nell to the ancient moss-covered gates of the first castle, the sun was shining horizontally across the meadow and the air was becoming a bit chilly. Nell wrapped herself up in a thermogenic shawl and set the thermostat for something a little on the cool side of comfortable; she had found that her wits became dull if she got too cozy. The basket had a thermos of hot tea with milk, and the sandwiches would hold out for a while.

The highest of the castle's many towers was surmounted by a great four-sailed windmill that turned steadily, even though only a mild breeze could be noticed at Princess Nell's altitude, hundreds of feet below.

Set into the main gate was a judas gate, and set into the judas was a small hatch. Below the hatch was a great bronze knocker made in the shape of a letter T, though its shape had become indistinct from an encrustation of moss and lichens. Princess Nell operated the knocker only with some effort and, given its decrepit state, did not expect a response; but hardly had the first knock sounded than the hatch opened up, and she was confronted by a helmet: For the gatekeeper on the other side was dressed from head to toe in a rusty and moss-covered suit of battle armor. But the gatekeeper said nothing, simply stared at Princess Nell; or so she assumed, as she could not see his face through the helmet's narrow vision-slits.

"Good afternoon," said Princess Nell. "I beg your pardon, but I am a traveler in these parts, and I wonder if you would be so good as to give me a place to stay for the night."

Without a word, the gatekeeper slammed the hatch closed. Nell could hear the creaking and clanking of his armor as he slowly marched away.

Some minutes later, she heard him coming toward her again, though this time the noise was redoubled. The rusty locks on the judas gate grumbled and shrieked. The gate door swung open, and Princess Nell stepped back from it as rust flakes, fragments of lichens, and divots of moss showered down around her. Two men in armor now stood there, beckoning her forward.

Nell stepped through the gate and into the dark streets of the castle. The gate slammed behind her. An iron vise clamped around each of Princess Nell's upper arms; the men had seized her with their gauntlets. They lifted her into the air and carried her for some minutes through the streets, stairs, and corridors of the castle. These were completely deserted.
