Not at all the same.
"How are we, Kaye?" Mitch asked, standing beside her at the sink.
"Stella is going to be fine," Kaye said before she could think.
"How are we, we, Kaye?" Kaye?"
Kaye reached out and gripped Mitch"s hand on the counter. She had not spent much time lately simply touching her husband. He had been gone so much, and so often, of course.
She must have looked miserable and lost. But what she felt was very, very physical.
Mitch pulled her close. He was always the one to make the first move; except that she had made the move that had produced Stella. Mitch had held back, worried about Kaye, or perhaps just scared at the thought of being a parent to a new kind of human being. They had been so in love, and the problem was, Kaye could not answer Mitch"s question now, not truthfully, because she did not know.
There was still love. What kind of love? "We are going to be better," she said into his shoulder. "There is certainly better to be."
"They shouldn"t hound us," he said with the boyish sternness of the night before.
"I don"t think we have any control over that."
"We won"t stay here long," he said, and glared out the window at the woods, the dock, the sunshine. "This place is too nice. I don"t trust it."
"It is is nice. Why not stay a while? The Mackenzies would never tell anyone." nice. Why not stay a while? The Mackenzies would never tell anyone."
Mitch brushed her cheek with his palm. "Their son is in a camp. The children in the camps are getting sick."
Kaye drew her eyebrows together. She could not follow this line of reasoning.
"Mark Augustine has been looking for you, for us. He"s been waiting for the right moment to reel us in. The illness is scaring people badly. This is his moment."
Kaye squeezed his forearm hard, as if to punish him.
"Ow," he said.
She loosened her grip. "We need to keep Stella quiet and calm. She needs to rest for a few days at least. She can"t rest in a bouncing Jeep."
"All right," Mitch said.
"We"ll stay here," Kaye said. "Will it be okay?"
"It"ll have to be," Mitch said.
Kaye leaned her head against Mitch"s chest. Her eyes lost focus and then closed. "Is she still asleep?" she asked.
"Let"s check," Mitch said, and they walked together into the living room.
She was. Kaye took Mitch"s hand and led him into the bedroom. They took off their clothes, and Kaye pulled back the covers on the bed until the bottom sheet was completely revealed.
"I need you," she said.
Her fingers on his lips smelled of tea leaves.

OHIO.
d.i.c.ken had prepared and racked up his seventy specimen sets. He used a Kim Wipe to take the sting of sweat out of his eyes. His sense of urgency was extreme but counterproductive. He could work no faster than produced good results. Anything less would be worse than not having worked at all.
He had labored nine hours straight, first separating and cla.s.sifying the specimens based on his labels and field notes, then preparing them for the automated lab equipment. Most of the manual labor involved preparing specimens and racking them up for runs through the instruments.
PCR instruments had been the size of large suitcases when he had been a student. Now he could hold one in the palm of his hand. The racks carried what had been the equivalent of a whole building full of equipment fifteen years ago.
Oligos-small but highly specific segments of DNA mounted in each tiny square cell of the whole-genome array chips-attached themselves to complementary segments of RNA expressed by the cell, including viral genes, if any, and labeled them with fluorescent markers. Scanners would count the markers and approximate their positions in the chromosome sequence.
From a prepared set of serological fractions, the sequencers would amplify and a.n.a.lyze the exact genetic code of any viruses in the samples. The proteomizers would list all proteins found within the targeted cells-both viral and host proteins. Proteins could then be matched by the Ideator to the open reading frames of the sequenced genes.
All this would give him a road map of the disease at the cellular level.
He tapped commands into the server controlling the lab machines. Fortunately, the code gaining entry to this computer had been simple to guess. He had tried combinations of JURIE and ARAM and, finally, ARAMJURIE#1, and that had worked.
The lab filled with humming and faint clicking, first to his right, then to his left. d.i.c.ken stood up and checked the progress of the little plastic tubes marching in their metal tracks one by one into the prissy little mouths of the white-and-silver machines. He had to admire the way the doctors had set up the lab. It was economical, the equipment neatly arranged, with good flow-through from task to task.
Jurie and Pickman had known their business.
Still, virus hunters who fled at the first signs of a disease were not highly regarded by their peers. Very likely, Jurie and Pickman had never chased down viruses in the field. They had behaved more like lab lizards, pale from lack of tropical sun, utter cowards when confronted by their real prey.
For a moment, d.i.c.ken felt a chill. How dumb of him not to think of it earlier. Jurie and Pickman had already done the work, discovered the results; that was why they had run away. The results had been very bad. The results had been very bad.
But d.i.c.ken had found no sign of specimen kits anywhere in the lab. The equipment had barely been used, it was so new.
The chill pa.s.sed, but slowly.
An hour later, he tapped the s.p.a.ce bar on the keyboard to turn off the screen saver. A flashing green bar with "Eureka!" written across it told him he had results. The results were displayed first as thumbnails on a grid, then, at his command, as a slide show.
With grim satisfaction, d.i.c.ken saw that he had isolated a recombined variety of unencapsulated RNA virus from the blood and sputum of all the afflicted children, in t.i.ters sufficient to suggest ma.s.sive infection. No other t.i.ters were so prominent.
From the beginning, seeing the buccal lesions and stomat.i.tis, d.i.c.ken had suspected c.o.xsackie A, known to cause most of the symptoms in the sick SHEVA children. But this strain was seldom a.s.sociated with fatal illness. c.o.xsackie B, however, sometimes produced myocarditis, inflammatory heart disease, in infants and children. According to Dr. Kelson, myocarditis was a possible cause of death in the outbreak. Kelson had said, "There"s ma.s.sive tissue damage. The heart just stops."
c.o.xsackie A and B typically spread by fecal contact or exchange of saliva. He did not know of any historical instances where it had spread by skin contact or in aerosols-droplets of moisture from breath or sneezing-or through residues left on surfaces, yet those kinds of transmission were necessary to explain the outbreak"s rapid and pervasive expansion.
Something had changed. c.o.xsackie A or B, or both, had suddenly become easier to spread, and targeted to a particular population not heretofore known to be vulnerable to most common childhood viruses.
Now that he knew the type of virus, he could focus on the origin of the disease and its etiology-how it had mutated, how it spread, and where it would be expected to spread next.
d.i.c.ken typed in a request for numerical results from each set of specimens, with identification of individuals and their circ.u.mstances. The computer prepared a table, but it was complicated and unintuitive.
d.i.c.ken took out a piece of paper and began organizing the results in his own favored plot. Using a small marker, he drew three large circles on the paper. Within the first circle he swooped a C, representing the children. Inside he drew a smaller circle, labeled IC for Infected Children. Outside the first, he drew a second large circle and labeled it BT for brave teachers and staff, those who had remained.
The third circle he labeled Tr, for traitors, those who had fled.
He picked up a red felt-tip pen and began categorizing the specimen ID numbers and marking them + or for their viral status. He then recorded them within the appropriate circles. Two of the circles rapidly filled with numbers and status marks. For now, there were no numbers in the Tr circle-he was leaving that open in case information from outside became available.
He now had points of proximity or actual contact and, presumably, opportunities for viral transmission. The pattern he saw emerging was already clear, but he refused to jump to conclusions. He did not trust either intuition or instinct. He trusted hard facts, indisputable a.s.sociations, and repeated correlations.
He drew the results a second way, in columns and rows. When he had completed his chart, he drew a new table, reversing the order, and filled the boxes with the categorized numbers.
d.i.c.ken cleaned up his work and tapped the plastic end of the pen on the columns, marching down, climbing back up, sweeping the marker to the right across the rows, color-coding the a.s.sociations.
Any way he drew it out, the pattern was clear.
Within the special treatment center, children who had had no contact with teachers or other students for more than three days had not contracted the virus. Eight children had been in isolation cells and had been abandoned when the staff evacuated. Three had died, but all of their specimens tested negative.
Five hours ago, Middleton had phoned the lab to tell d.i.c.ken that one of the rescued children had fallen ill, and Kelson said she was likely to die. That child had almost certainly been exposed after her "rescue."
d.i.c.ken had taken specimens from six children who had been locked in a shower room by a fleeing teacher, and not found until late yesterday. One had died from lack of special medication. None had had any contact with teachers or staff for the past forty-eight hours. Their specimens tested negative.
DeWitt and Middleton had identified fifty children whom they knew had had close contact with teachers and staff in the past sixty hours. Of these, forty had fallen ill, and twenty had died. All of their specimens tested positive. Somehow, ten had managed to avoid exposure.
He looked over the results for twenty-two teachers, staff, and security officers. All had had continuous contact with infected children for the past forty-eight hours. They were exhausted, stressed, worn down. Six of these-four nurses from the main pool and one teacher from the special treatment wing, and the counselor, Dewitt-tested positive for the virus, but in low t.i.ters compared to infected children. None showed symptoms of infection.
Neither he nor Mark Augustine tested positive.
d.i.c.ken held up his chart once more. The conclusions were compelling.
Only infected SHEVA children showed symptoms.
SHEVA children lacking recent adult contact tested negative for the virus and showed no symptoms.
Contagion did not spread from the children to adults with much efficiency, if at all; and if it was pa.s.sed on, did not cause illness in adults.
Contagion probably did did spread from child to child, but the chain always began with children who had had recent contact with adults. spread from child to child, but the chain always began with children who had had recent contact with adults.
He had not gathered specimens from every child, alive or dead, or from all the adults that had been at the school; it was possible that an asymptomatic child was the source; it was also possible that exposed adults would get ill, eventually.
But he doubted it. The children were almost certainly not the source. And adults did not get sick. The river flowed in only one direction, downstream from teachers and staff, adults, to the new children.
The computer chimed again. d.i.c.ken looked at the screen. The Ideator had identified a sequence from its standard human genomic library. He touched a box on the screen. It expanded outward, showing a gene map for an obscure and defective HERV. c.o.xsackie viruses-for that matter, the superfamily of Picornaviridae-had never been known to recombine with legacy retroviral genes. Yet he was looking at a protein traced to a gene from the suspect virus, and it was very similar-90 percent h.o.m.ologous-to a protein once coded for by an ancient human endogenous retrovirus found in two chromosomes.
The presence of the protein converted a relatively benign RNA virus into one that killed, in large numbers.
He typed in another search. The Ideator scanned the Genesys bank for a match within the 52-chromosome genome of the new children. According to the Genesys bank, that particular defective primordial HERV did not exist in any SHEVA child.
Both of its copies had been discarded during the supermitotic splitting and rearrangement of the old chromosomes.
d.i.c.ken stared at the screen for several minutes, thinking furiously. His vision blurred. He grabbed the crumpled wipe and dabbed again at his face. His left leg cramped. He pushed away from the bench and walked around the small lab room, bracing on tables, equipment.
What Augustine and the Emergency Action people feared most had happened. Ancient viruses had somehow self-corrected and contributed one or more novel genes to a common virus, producing a deadly disease. But the recombination had not taken place in SHEVA-affected children.
It had begun in adults.
Adults were creating viruses that could infect and kill the SHEVA children. Those same viruses did not harm the adults. d.i.c.ken could yet be sure, but he suspected that the viral protein took advantage of yet another protein expressed only in the children-two units not in themselves toxic, but lethal in combination.
A new role for viruses: agents of a species-level immune response. Biological warfare, one generation against another.
An old species trying desperately to kill the new? Or just an awful mistake, a slip-up with deadly consequences?
He secured the samples, backed up the computer files, made a set of printouts, locked up the lab, and brutally shoved the outer door of the research building. It slammed open, and he walked out into the glare of the afternoon sun.

Mitch had put on one of George Mackenzie"s white terry robes to check on Stella. He now lay on the bed beside Kaye, the robe ridiculously short over his long legs. His breathing was even. She could feel his hand, large and wide, with long, thick fingers, resting on her arm.
Kaye rolled over and put her head on his chest, where the robe had pulled open. "Have I been acting a little crazy?" she asked.
Mitch shook his head. "Defensive."
"Do you remember before we were together? You were doing archaeology. I was working away madly, and confused."
"I wasn"t doing much archaeology," Mitch said. "I"ve been out of action for longer than I"ve known you. My own d.a.m.ned fault."
"I loved your rough hands. All the calluses. What would we be without Stella?"
Mitch"s eyes narrowed. Wrong question.
"Right," Kaye said. She lay back on the pillow. "I insisted. We don"t have any other life now."
"I helped," Mitch said.
"I"ve neglected you. In so many ways."
Mitch shrugged.
"What do you want for Stella?" Kaye asked.
"A reasonably normal life."
