The room was huge. The bed was big enough for six, eight if they were friendly; but you could probably lift it with one hand. All of the furniture was cast out of flexifoam; it had that bouncy-fluffy look.

I wondered what Lizard had intended by this arrangement. Which bedroom was I going to sleep in tonight? So far, she"d given me no clue at all.

"Do you want me to hang these up for you?" Shaun held up my duffel.

"Uh, no. It"s all right. Just toss it in the closet." The closet alone was big enough to park a car in.

"Bathroom"s in here. The tub is probably a little deeper than you"re used to, so be careful. It"s three meters long; this controls the water jets, this controls the bubbles; the spa is automatically timed. Don"t worry about the water, the law only requires one trip through the recycler-we give it three before it"s used again. This panel controls the tanning lights. This gives you steam, this gives you dry heat; please keep the gla.s.s door closed when you"re using the sauna. This is the ma.s.sage table. You know how to use one, don"t you?"



I nodded, dumbly. "Are all the cabins outfitted like this?"

"We have only one cla.s.s of accommodation."

"This is amazing."

"Yes, sir. That"s our name. Out here"s the balcony. See that light? When it"s red, the windows are automatically locked. There"ll be a chime and the light will turn green when it"s okay to go out. Then it automatically unlocks. Over here"s the bar.

We restock it every morning. The Sober-Ups are down here. These are extra-strength; they"ll give you quite a synaptic buzz while you"re coming down, so you"ll want to be careful with them. If you have any specific tastes in liquor or soft drinks, let me know, or punch it into the terminal here. The ship"s library is one of the best in the world. Just punch here for index. You"ll find videos, music, books, reference works-oh, yes, we"ve got a full military library too, including a connection with all three of the military and science networks. The phones are standard; it"s a full video link."

He led me back into the living room. "There"s a projection screen in here. This b.u.t.ton lowers it, see? Don"t worry about playing your music or your movies too loud. Every room has three feet of foam insulation. Here, this is the help b.u.t.ton. It explains everything that"s available in the cabin or anywhere on the ship." He smiled at me brightly, "If you have any other questions, I"d be happy to answer them."

I felt like I was out of breath. "Shaun," I said. "I have this feeling that it doesn"t matter what I could think of. You"ve probably already found a way to provide it, right?"

"Well..." he began.

"What?"

"There was a pa.s.senger once who asked room service to send him up an elephant ear on a bun."

"And-?"

"Well, it was late, and the kitchen had been busy. We were out of buns."

I laughed in spite of myself. "That joke is so old, it"s wearing suspenders. Is there anything else I need to know? Which b.u.t.ton do I press for the harem?"

I"d said it only as a casual wisecrack, but Shaun merely stepped over to the help panel. Without batting an eye, he called up the Companionship menu and displayed it on the wall-sized projection screen. "Male or female?" he asked.

I was so startled, I couldn"t answer. I just shook my head as if it didn"t make a difference.

"We have a very enthusiastic staff," he said. "And many of the attendants are also available for ma.s.sage and bed-warming services." He started flashing pictures on the huge screen, alternating between handsome men and attractive women of all types and yes. Only a few were completely nude; most of the poses were as innocently seductive as photos taken at a friendly beach party. There was nothing salacious at all about the presentation.

"If you see anyone you like," said Shaun, "you can make a reservation right now.

It"s part of the service package; everything on the ship is covered under the Authority contract." He explained, "It"s already paid for. So you might as well take advantage."

I didn"t know whether to be embarra.s.sed or delighted. I"d thought I"d seen everything. Once again, I"d been wrong. "Bedwarming. I liked that. Nice euphemism." The company offered the service, the pa.s.sengers partook; the boys and girls earned a little extra-or a lot-the company took a commission and billed the Authority. I could have been offended at the waste of money, but the money was worthless anyway. Only not everybody knew it yet.

As an afterthought, I asked, "Is your picture in there?" Shaun punched another b.u.t.ton, and a wall-sized display of Shaun wearing nothing but a smile and a towel appeared. Actually, he wasn"t even wearing the towel. He was just holding it stretched out in front of him. He was nude, facing away from the camera, facing a mirror, and looking back over his shoulder at the photographer with a happy expression. It was the cla.s.sic Betty Grable pose. The full-length minor would have revealed all of the rest of his charms, except for the towel he was holding-it was a very small towel-across his loins, but he was holding it tight enough against his body to outline that part of his anatomy that a prospective customer might be most curious about. All in all, it was obvious that Shaun knew his business-as well as his pleasure. I glanced from the screen to Shaun. He smiled happily back. Well, that answered that. But I still found it difficult to accept casually. I guessed I was an old-fashioned girl after all.

"Would you like me to come by after dinner tonight?" he asked. "I"d really like to," he offered.

A nasty thought flashed quickly across my mind; I wondered if he really meant it, or if he was supposed to say that. Did he say that to every pa.s.senger?

"Um-" I began. "Thanks, Shaun. That"s the nicest offer I"ve had in a long time, and maybe under other circ.u.mstances, I"d take you up on it, but I"m in a relationship right now. I don"t think it"d be appropriate." It was my all-purpose answer, a safe way of saying no without hurting anybody"s feelings. Curiously this time, every word of it was true.

"Sure," he said. "If you change your mind, let me know. I"d really like to wrestle with you. You"re real s.e.xy." He handed me the plastic card. "Here"s your key. I"ll be your regular attendant. Mitzi will also be available later today." He started for the door. "Oh, wait a minute, Shaun." I was fumbling in my pocket for a ten-casey coin.

"Thanks, but that"s not necessary. Tips are already covered too." I must have looked surprised, because he said, "It"s part of our job not to accept tips. We"re paid well enough that we don"t need them or want them." For the first time since he"d begun his proud tour of the airship, his smile faltered and he looked embarra.s.sed.

He said reluctantly, "In fact, offering a tip is almost an insult aboard this ship. We"re not hired help. We"re hosts. Our sole purpose here is to make sure that you"re completely comfortable."

"Oh," I said, shoving the coin back into my pocket. "I didn"t realize."

"Captain McCarthy, may I speak candidly?"

"Of course."

His professional demeanor disappeared instantly, and for just a moment he became only a sixteen-year-old boy again. "You-everybody on this ship-you"re the war effort, all of you are. You don"t know how much you"re envied. You"re doing something. This is as close as I"m probably ever going to get. I know my job doesn"t seem very important to you. I mean, a lot of you guys just think we"re servants and-well, you know. We don"t mind. We feed you and change your bedding and give you ma.s.sages and hugs if you want them, and once in a while one of you even lets down his or her guard long enough to let us care about you. I know that seems strange to hear, but we really do care about our guests here. We"re trained to care. I started training for this duty when I was twelve."

Shaun looked like a small boy visiting a military base for the first time; his eyes were filled with awe and wonder. "You guys, all of you, you"re our special guests.

You"re not just customers, you"re the people who are going to win the war for us. So if there"s anything we can do to put you at your best, then we"re helping to win the war too. This is our part of the victory. Taking care of you. It"s a privilege for us to do that."

Despite myself, I was touched. And despite myself, I was skeptical too.

Part of me was saying that Shaun"s speech was a very clever act. I"d just seen one more part of the service provided by the company. Everything here was part of the fantasy that you are special. That"s what the company was really selling. Not just long peaceful air cruises, but powerful emotional restoratives.

Even so... even knowing what I knew, I wanted to believe it anyway. I wanted to let go and swim in the soft sea of luxury. And, what the h.e.l.l did it matter if I believed or not? Even if I knew it was fake, it was still true. Shaun"s job was to take care of me so I could help win the war.

And then I had to laugh at myself. Even when it"s true, I don"t believe it. And then I stopped laughing-the a.s.sumption here was that I could help win the war. And that wasn"t necessarily a valid a.s.sumption. n.o.body even knew if the war was winnable anymore. But...

I looked across at Shaun. He was still waiting for my reply. I reached out to tousle his hair, then at the last moment realized that was something a man did to a boy. Instead, I put my hand on his shoulder and patted him gently. "Y"know something. I can"t remember the last time somebody told me he just wanted to make me happy. At least, not without a hidden agenda. It"s been a long time." I shrugged and accepted the circ.u.mstance. "Thanks. I promise I"ll do my best to be as comfortable as I can. If you see me tensing up, hit me with a club and give me your ten best suggestions for getting happy again, okay?"

He grinned happily. "Yes, sir!" And threw me the sharpest salute I"d ever seen.

What the h.e.l.l. I saluted back. I felt silly as h.e.l.l doing it, but what the h.e.l.l. At least his was the most honest salute I"d ever received.

Before the Chtorran plagues could be initiated into the human population, before any agent of transmission could begin the job of infection, a reservoir of disease germs had to be established for those agents to draw upon.

The process of infection requires-demands-a reservoir. Some host mechanism must first be present in which the disease-causing agent can exist indefinitely. The process of transmission and infection cannot occur without a biological partner providing storage and reproduction facilities for the germs.

If we are to accurately establish the method of Chtorran colonization, it is essential that we identify that reservoir of infection. Where-or what-is it?

-The Red Book, (Release 22.19A)

Chapter 32.

The Long Briefing "The only acceptable subst.i.tute for brains is silence."

-SOLOMON SHORT.

General Tirelli entered the room from the back. She didn"t even glance at me; she just strode forward down the center aisle and up onto the dais. Several tugboats followed in her wake; that was what I called the inevitable troop of aides and a.s.sistants who followed every command-level officer. I"d made it a personal hobby to gauge the styles of the different tugboats as they delicately maneuvered various high officials into position, setting up microphones, cameras, briefing books, pens, notepads, and water pitchers. What I liked about Lizard was the way she brushed the tugboats impatiently aside and got immediately down to business. I noticed that Dwan Grodin, the electric potato, was sitting quietly in the front row of chairs.

"Would you all please be seated?" Lizard asked loudly. She waited with visible impatience. I thought about grabbing a chair, they looked comfortable. I"d sluiced away as much of Mexico as could be scrubbed off my skin, put on clean underwear and a neutral jumpsuit, and felt a lot better physically than I had in days; but I was still feeling surly. Mostly about Lizard right now. I didn"t like the way she"d brushed by me so coldly. So I ignored her request and decided to stand instead. I drifted over to the back of the room and positioned myself right next to the exit. I folded my arms against my chest and leaned nonchalantly, but deliberately, against the wall-and thought about my promise to Uncle Ira. This wasn"t going to be an easy one to keep.

I studied the twelve-man combat team just filling up the last row of chairs. They"d been a.s.signed to the mission at my recommendation, despite protests from the Science Section that the s.p.a.ce could better be used for twelve more scientists.

Furthermore, the weight allowance for all that heavy military gear could be better used for more probes and monitoring equipment. Lizard had backed me up on the need for a security squad, and that had been that. But this wasn"t the team I had picked. I had picked a squad of battle-hardened veterans, men and women I"d worked with. The troops I had picked looked like they"d been chiseled out of a rough stone cliff. These soldiers were children. They were tall, they were broad-shouldered and straight-backed, they had great posture. You could use them for doorposts. They were all annoyingly clean and bright and attentive; but the only thing chiseled about them was their cheekbones.

To the untrained eye, these kids might have looked like combat-ready troops-especially in comparison to all the flabby scientists around them, most of whom looked as if they had been sewn together out of big pink bags of jelly; but I knew better. This was somebody"s drill team; they were here because they looked good. Maybe this was a reward for them; they"d been good and somebody decided that they deserved a vacation and b.u.mped the muscled workhorses off the roster to favor the pampered thoroughbreds. These kids were too confident, too self-a.s.sured; they were big and strong and friendly-looking. That was the giveaway. They didn"t have the narrow look of death in their eyes. They didn"t have the right sense of spiritual exhaustion and mordant resignation, they didn"t have the inner core of silent hardness. They were virgins. I hoped to G.o.d they wouldn"t be needed for anything more strenuous than carrying luggage to the exit lobby. I wondered whose good idea this had been and why Lizard had let it happen.

A six-meter projection screen dominated the forward wall of the main lounge.

Lizard stood in front of it and looked out across the room. The lounge was arranged theater style, and every man and woman a.s.signed to the mission was present. There were 180 of us. The Latin Americans were sending an additional team of 85 who would meet us in Amapa. My gut-level feeling was that we had too many scientists and a.s.sistants and not enough combat veterans. I knew that we weren"t planning any drops, but... I also knew that accidents only happened when you didn"t prepare for them.

"Congratulations to you all. Operation Nightmare is officially underway-" Lizard began. She had to wait until the applause died down before she could continue.

"We"re exactly one year and one day late, but we"re on our way. Dr. Zymph a.s.sured me before we left that the Chtorrans would still be there waiting for us, and all of our surveillance seems to bear out her prediction, so the trip won"t be wasted." There were only a few polite chuckles. Stand-up comedy was not Lizard"s forte, and she knew it. She took a paper out of her breast pocket. "I have a note here from the President. She says, "General Tirelli, I don"t have to tell you how important your work is. You and your dedicated team know that better than anyone. Know this, that you are traveling with the hopes of an entire planet. You carry with you the best equipment, the best information, and the finest support that the United States can provide. You also carry our most heartfelt hopes for a speedy and successful resolution of your work. I look forward to the opportunity to personally thank each and every one of you for a job well-done. You have my complete confidence, and you have the best wishes of the people of the Earth."" Lizard refolded the note and slipped it back into her pocket without comment.

She continued brusquely. "We"re carrying with us several observers from the Brazilian government-" She had to wait again until the applause died down. "I see that some of you have already met Dr. Julian Amador and Dr. Maria Rodriguez. It"s an honor to have the both of you aboard. Let me also introduce Amba.s.sador Jorje-Molinero, who will be traveling with us, acting as our host and our liaison, at least as far as Amapa, and he"ll be reporting on our operation directly to his government, so please give him your utmost cooperation." That Amba.s.sador Jorje-Molinero did not receive as warm a welcome as the two scientists did not go unnoticed. The strained relations between the North American Operations Authority and the Latin American Security Council were no secret; things had been especially tense since the liberation of South Mexico-and the Brazilians had been among the most vocal in their objections. As a result, Operation Nightmare was no longer simply a high-intensity surveillance operation. Now it carried a lot of political baggage; it was also an attempt to thaw out the frozen relations between two superpowers. Neither Amba.s.sador Jorje-Molinero nor General Elizabeth Tirelli appeared particularly sanguine about the situation.

Lizard cleared her throat and continued. "Dr. Oshi Hikaru, the Brazilian science minister, will be boarding at Amapa as our official liaison for the primary part of the operation." She hesitated as if considering how best to phrase her next statement, then plunged directly into it. "Some of you in this room have had some unfortunate experiences with individuals representing themselves as experts in the field-"

That was an understatement; she could just as correctly have said that the t.i.tanic had a rough crossing. Lizard"s comment drew more than a few nods and smirks, and I wasn"t the only one who snorted derisively. The only growth industry left on the planet was the bureaucracy of information specialists feeding on the Chtorran invasion.

"Yes, we"re aware of the problems that you"ve had elsewhere," Lizard acknowledged. "Let me just say this. This is not that kind of situation. The Brazilian government has invested a larger proportion of its available resources in the study of the Chtorran infestation than any other government on this planet. Their commitment to this operation in particular has been one of absolute dedication. You"re going to find that the information that the Brazilian specialists have gathered-that they"re continuing to gather even as we speak-is as complete and detailed as anyone could ask for. I"m sure that you"re all going to be very pleasantly surprised when you sit down to speak with the scientific staff who will be joining us in Amapa. We are not starting from scratch here; please be aware of the tremendous job that our hosts have accomplished."

She glanced over at the amba.s.sador. His expression was stern and unforgiving.

He looked like someone had ordered him to unruffle his feathers and he"d found the task very nearly impossible. Lizard turned her attention back to the rest of us. "I want to remind you all that this mission is a cooperative venture. We are here at the invitation of the Brazilian government. We are their guests. Please remember that in the way you conduct yourselves and your business. Please be good guests." She stressed her last words carefully. "Read. Your. Briefing. Books."

She looked around at the various officers and scientists; as if checking her memory to see if she"d forgotten anything. No. Satisfied, she stepped over to the podium, broke the seal on her own briefing book and opened it flat before her. She barely glanced at the first page. "Now then, if you"ll turn your attention to the screen behind me-" The inevitable map of the Amazon basin appeared. "We"ve had complete satellite observation over the three largest nodes of infestation for nearly two years now. Alpha target is here, just east of where the river j.a.pura crosses from Colombia into Brazil; Beta is north of Coari, where the Carabinani pours into the basin; and Gamma is down here where the Rio Purus crosses eighty kilometers of wetlands. We"ve had skyb.a.l.l.s, badgers, wasps, and spiders probing all three camps, and we"ve also sprayed with nanoprobes on four different occasions. We think we have a pretty good picture of each of the settlements. Dr. Silverstein"s team has done a great job of mapping the targets; and Dr. Brown"s group has done an equally fantastic piece of work cataloging the data, even to the point of identifying many of the individual specimens in each of the locations. Thank you all."

She held up a hand, a signal that she was adding a personal aside. "As you know," she said quietly, "there are those who believe that electronic observation has been and will continue to be sufficient to our needs and that it is extremely unlikely that this operation will add any significant new knowledge to our understanding of the Chtorran infestation. Obviously, I don"t agree with that. I doubt anybody else here subscribes to that view either. I think we"re all here because our collective need to see this phenomenon firsthand and find out what"s actually happening in these settlements outweighs our individual concerns for personal comfort and safety."

There was a rustle of good-natured laughter at that.

Lizard pretended not to hear it. She continued, keeping a straight face the whole time. "I know the sacrifices you"ve made to be here, the discomforts that you"ll have to endure... and I can"t think of a better demonstration of your commitment to the expansion of human knowledge than your presence aboard this ship, and I thank you for that." She looked over the room, allowing herself a gentle smile and a nodding appreciation of the elegance of our surroundings. Her gaze took in the rich paneled walls, the high gleaming ceilings, the magnificent chandeliers, the soft rugs and deep chairs, and by inference, all of the rest of the luxurious airship beyond these walls as well. She waited until the last of the good-natured laughter and applause died away.

"Seriously," she added, speaking in a sterner tone now, the ironic twinkle vanishing from her eyes. "There is a risk here. I won"t understate the danger. But I"m absolutely convinced that if we observe all of our safety precautions, this should not be a dangerous job. You"ve all been trained, you"ve all been extensively briefed on what the dangers are, I don"t need to repeat the cautions. Let me just remind you again that there"s no room for carelessness here. We"re fragile. We"re vulnerable.

We"re going to be a long way from help. But we shouldn"t have any problems if we stay awake and pay close attention to what we"re doing. All of us."

She swept her gaze slowly across the room, as if she were meeting each person"s eyes in turn. I waited for her to meet mine, but she swept on past, as if I had somehow turned invisible without my noticing. Gaddammit! I wanted to confront her. I thought you wanted me he-re!

"All right," she said, turning the page of her briefing book. "Let"s talk target. The Carabinani and Purus settlements are close enough to Coari that we"re concerned about human influences on the camps. The Purus camp has also got the disadvantage of being very marshy. The j.a.pura settlement is higher ground, but it"s more than six hundred kilometers further inland. It"s going to be harder getting in and harder getting out. I"ll be honest about it; n.o.body wants to go to j.a.pura. Captain Harbaugh says it"s an extra day"s travel each way and there isn"t going to be any ground support available west of Manaus. Nevertheless-" She paused for effect and looked out across the room. We all knew what she was going to say.

"Nevertheless... the j.a.pura infestation is the oldest and largest of the three, and it has had the least contact with human beings. It appears to be the Chtorran equivalent of a city."

She turned back to the podium just long enough to consult her notes, then hit the screen with her pointer again. "All right, I"m about to discuss some things that are of a delicate nature. For the moment, I want you to put aside any feelings you may have about international relations and concentrate on the information presented." As she said this last, she was looking directly at Amba.s.sador Molinero. The amba.s.sador"s expression remained unreadable.

"The Colombian government shared this information with us only very recently, and it"s with their permission that I reveal it here. I hope you"ll appreciate the importance with which they regard this matter, and the trust implied by their candor.

They have been launching observation flights from Yuana Moloco, sending them across the border to overfly the j.a.puran infestation. Apparently the gastropedes have been foraging rather heavily to the west. Some of the j.a.puran worms have been sighted nearly a hundred kilometers into Colombian territory, and the Colombian government is quite concerned about the Indian tribes in the region.

"This in itself is not cause for immediate alarm, but the overflights have revealed a human presence in the j.a.puran infestation, demonstrating that the Chtorrans are not simply capturing humans for food; they"ve found a way to subjugate them and use them as slaves. We"ve suspected it for some time. Now we"re almost certain of it."

Lizard paused to let the impact of this news be felt in the room. I looked around to see how others were reacting. They looked like they"d been slapped. Their faces were ashen. Some of them simply stared at the floor. The rest looked to her for relief, but she only nodded in grim confirmation.

"As most of you know," she continued, "we first observed a human presence in a major Chtorran settlement a year and a half ago, in the Rocky Mountain area. That infestation was terminated by the application of two nuclear devices. We have maintained close surveillance of the area ever since, watching to see if the gastropedes will attempt to recolonize, and if so, how rapidly the process occurs.

The nuclear option still remains on the menu.

"The human presence in the Rocky Mountain infestation was a.s.sumed to be voluntary. The photographic evidence suggested that we were dealing with a tribe of renegades who had somehow learned to cooperate with the Chtorrans and live among them as symbiotic partners. It was that fact which allowed us to justify the use of nuclear devices.

"Unfortunately, we cannot make the same a.s.sumption about the human presence in the j.a.puran settlement, and in any case"-here she threw another look to the amba.s.sador-" the Brazilian government and the Latin American Security Council both remain adamantly opposed to the use of thermonuclear devices as a controlling agent. So that particular issue is not our concern. Any change in that policy is not going to be decided here, or by us. However, our recommendations at the conclusion of this mission will carry considerable weight for both the North American Operations Authority and the Latin American Security Council, so please keep that in mind."

Lizard looked very grim now. She put both hands on the sides of the podium and leaned intensely forward, as if she were speaking to each of us one on one. "Our concern about the human presence in the j.a.puran infestation is that if the Chtorrans are now capturing humans, either for use as slaves or for food, what actions can we responsibly take against the settlements? What is our moral position here? Can we extract human captives from a Chtorran camp? At what cost? Are we morally obligated to make the effort? I don"t know that we can answer these questions here either. I do know that it is vitally important that we determine exactly what the Chtorrans are doing with the human beings they capture, because that will determine our ultimate response."

She took a breath and turned the page of her briefing book. "There"s another matter that I want you to be aware of. For the past two years we"ve been charting the activity levels of each of the nodes of infestation. All three seem to be on the same cycle: first there"s a spurt of very rapid growth and expansion, followed by a long period of a.s.similation, then another period of rapid growth. But each spurt of growth is not simply a physical expansion of the settlement; it"s also a transformation of the whole behavioral pattern of the camp. Even the aerial appearance of the, mandala shifts."

Without additional comment, she stepped aside to let us see a wide-angle aerial view of the j.a.puran infestation. The huge screen showed a two-year time-lapse series of satellite photos. The mandala shape of the infestation was unmistakable. The worms had laid out their largest huts and corrals around a central core; then they had wound their avenues of traffic around and around that core. As the mandala had expanded, new rings of structures had grown up around the perimeter. The result was not quite a spiral and not quite concentric, but somehow both. The effect was eerily beautiful, like the waves of petals in a chrysanthemum. s.p.a.ced equally along the various axes, we could see other circular structures: mini-mandalas, that made me think of the eyes in a peac.o.c.k"s feathers. Each of the eyes was clearly a center of activity and growth.

As the time-lapse series progressed, we could see the ebb and flow of movement throbbing throughout the camp. The waves of activity moved across the great settlement like a pulse, as if there were a physical heart beating beneath it. We began to see a rhythmic pattern of growth underlying the movements. The mandala shape of the camp seemed to swirl in and out, and the overall pace of activity rose frenziedly until it seemed that the whole camp must surely burst because it could no longer contain such madness; then there would be a momentary hesitation, a series of throbs, and then a sudden rapid expansion outward, like flames of blood and fire slashing into the dark green forest. They were acrid scarlet waves, encroaching swiftly, curling around and around, encircling each new area, enclosing it to form intricate new patterns; and ultimately overflowing everything green until each last dark island of jungle vegetation winked out of existence.

Then, in the silent aftermath, the new worm huts would begin appearing, popping up like mushrooms, each one taking its mathematically precise position within the expanding mandala. The new structures grew within the curling protection of the outermost waves of expansion; it was clearly an act of deliberate colonization and a.s.similation of territory. The huts and the cl.u.s.ters of corrals that surrounded them grew slowly at first, as if the sudden thrust of expansion had exhausted the energy of the entire camp; but even as we watched, we could see the pace of activity beginning to pick up again as the cycle turned inexorably toward the next incredible explosion of life.

It went on and on. Swirl, throb, expand. Each expansion was frighteningly larger than the last one-and just as Lizard had said, each expansion seemed to transform the whole camp. With each new incarnation, the patterns of color and movement would become more intricate and complex. They were clearly an evolution of what had gone before, but they Were not predictable evolutions. Perhaps an expert in chaos theory might be able to determine what was happening here. I could see only the patterns. To me, each evolution seemed as baroque and as beautiful as a Mandelbrot? * zoom, both natural and alien at the same time.

Abruptly the image cleared and Lizard stepped back in front of the screen. "As you can see, we"re approaching the end of one cycle and the beginning of the next.

We expect to see a new period of expansion starting some time next month. We think it"s a function of population density. When the cup gets filled too tightly, it breaks, and the contents spread out in all directions.

"What worries us about this next period of expansion is that the j.a.puran settlement has reached the limits of what the local geography will allow. It can"t get any bigger. It can"t support any more Chtorrans. What"s going to happen when this settlement hits the limit to its growth? An irresistible force is about to hit an immovable object. We think-and I caution you that this is only a hypothesis-we think that the infestation will adapt to the circ.u.mstance in some totally unexpected and unpredictable way. Uh, let me clarify that. What you"re not seeing in the aerial views are the intricate patterns of life that are occurring deep within the camp. The visible patterns of the settlement are simply the surface expressions of much deeper forces.

Each expansion, each transformation, represents new symbioses, new patterns of cooperation, new behaviors among the Chtorran species never previously observed.

"Right now our best guess is that each expansion represents a critical threshold of density necessary for those behaviors to occur. When a threshold level is reached, the new behaviors begin, the mandala is transformed-raised to the next level of efficiencyand the expansion results.

"We think that what we"re seeing now is a penultimate stage where all the separate pieces of the ecology have finally all become active, all in one place, and that the next transformation of behavior will not be simply a physical expansion of the camp, but something much more than that. Perhaps we are going to see a volcanic explosion of Chtorran life, a physical tidal wave of expansion that devours everything before it, as pitilessly and as relentlessly as the spring flooding submerges the delta." She hesitated. "That"s our best guess. I hope to G.o.d we"re wrong. But...
