Chase had gone pale. “How do we prevent that, Ms. Browning?” he asked.
“If chipping cannot be implemented immediately, we'll resort to older methods. Ankle bracelets will be attached to monitor the activities of affected males. Other plans are being drawn up even now. We willprevent this new surge of disease, Senator.”
“How long until we can cleanse our bodies of these viruses completely?” Senator Percy asked.
“That's Ms. Lang's area of expertise,” Browning said, and turned to her with an ingenuous expression, one professional to another. “Kaye? Any progress?”
“Our division is trying new procedures,” Kaye said. “So far, we have been unable to remove legacy retroviruses—ERVs—from mouse or chimpanzee embryos and proceed to live birth. Removing most or all of the ancient viral genes, including SHEVA genes, produces gross chromosomal abnormalities following mitosis, failure of fertilized eggs to implant, early absorptions, and miscarriages. As well, we have not made progress at Americol with any effective vaccine. There's a lot to be learned. Viruses—”
“There it is,” Browning interrupted, turning back to the senators. “Utter failure. We have to move now with practical remedies.”
“One wonders, Dr. Rafelson, whether or not you are to be trusted with this work, given your sympathies?” Senator Percy said, and mopped his forehead.
“That's uncalled for, Senator Percy,” Gianelli said sharply.
Browning swept on. “We hope to share all scientific data with Americol and with this committee,” she said. “We sincerely believe that Ms. Lang and her fellow scientists should be as forthcoming with us, and perhaps a tad more diligent.”
Kaye folded her hands on top of the table.
After the session was gaveled to a close, Augustine sipped a glass of water in the waiting room. Browning walked briskly by.
“Did you have anything to do with this, Mark?” she asked in an undertone, pouring herself a glass from the frosted pitcher. Three years ago, he had underestimated the fear and hatred of which Americans were capable. Rachel Browning had not. If the new director of Emergency Action trailed any rope, Augustine could not see it.
Many more years might pass before she hanged herself.
“No,” Augustine said. “Why would I?”
“Well, the news will get out soon enough.”
Browning turned away from the door to the waiting room as Kaye was ushered in by Laura Bloch, and slipped away with her counsel. Bloch quickly secured Kaye a cup of coffee. Augustine and Kaye stood less than a pace apart. Kaye lifted her cup. “Hello, Mark.”
“Good evening, Kaye. You did well.”
“I doubt that, but thank you,” Kaye said.
“I wanted to tell you I'm sorry,” Augustine said.
“For what?” Kaye asked. She did not know, of course, all that had happened on that day when Browning had called and told him about the possible acquisition of her family.
“Sorry you had to be their decoy,” he said.
“I'm used to it,” Kaye said. “It's the price I'm paying for being out of the loop for so long.”
Augustine tried for a sympathetic grin, but his stiff face produced only a mild grimace. “I hear you,” he said.
“Finally,” Kaye said primly, and turned to join Laura Bloch.
Augustine felt the rebuff, but he knew how to be patient. He knew how to work in the background, silently and with little credit.
He had long since learned how to emulate the lowly viruses.

NEW MEXICO
To enter the Pathogenics zoo, they had to pass through a room with bare concrete walls painted black and dip their shoes in shallow trays of sweet, cloying yellow fluid—a variation on Lysol, Turner explained.
Dicken awkwardly swirled his shoes in the fluid.
“We do it on the way out, too,” Presky said. “Rubber soles last longer.”
They scraped and dried their shoes on black nylon mats and slipped on combination cotton booties and leggings, cinched around the calf. Presky gave each a snood and fine mesh filter masks to cover their mouths, and instructed them to touch as little as possible.
The zoo would have made a small town proud. It filled four warehouses covering several acres, steel and concrete walls lined with enclosures containing loose facsimiles of natural environments. “Comfortable, low stress,” Turner pointed out. “We want all our ancient viruses calm and collected.”
“Dr. Blakemore is working with vervets and howler monkeys,” Jurie said. “Old World and New World. Their ERV profiles are vastly different, as I'm sure you know. We hope soon to have chimps, but perhaps we can just piggyback on Americol's chimp project.” He glanced at Dicken with speculative brown eyes. “Kaye Lang's work, no?”
Dicken nodded absently.
The five large primate cages had most of the amenities: tree limbs, swings and rings, floors covered with rubber matting, multiple levels for pacing and climbing, a wide selection of plastic toys. Dicken counted six howler monkeys segregated male and female in two cages, with perforated plastic sheeting between: They could see and smell each other, but not touch.
They walked on and paused before a long, narrow aquarium containing a happily swimming platypus and several small fish. Dicken loved platypuses. He smiled like a little boy at the foot-long juvenile as it breached and dove several times through the clear green water, silvery lines of bubbles streaming from its slick fur.
“Her name is Torrie,” Presky said. “She's pretty, no?”
“She's wonderful,” Dicken said.
“Anything with fur, scales, or feathers, has viral genes of interest,” Jurie said. “Torrie's rather a dud, at the moment, but we like her anyway. We've just finished sequencing and comparing the allogenomes of echidnas and, of course, platypuses.”
“We're taking a census of monotreme ERVs,” Turner explained. “ERVs are useful during viviparous development. They help us subdue our mothers' immune systems. Otherwise, her lymphocytes would kill the embryos, because in part they type for the father's tissue. However, like birds, monotremes lay eggs. They should not use ERVs so extensively during early development.”
“The Temin-Larsson-Villarreal hypothesis,” Dicken said.
“You're familiar with TLV?” Turner asked, pleased. TLV stood for a theory of virus-host interactions concocted from work done over decades, at different institutions, by Howard R. Temin, Eric Larsson, and Luis P. Villarreal. TLV had gained a lot of favor since SHEVA.
Dicken nodded. “So, do they?”
“Do who, what?” Presky asked.
“Do echidnas and birds express ERV particles to protect their embryos?”
“Ah,” Presky said, and smiled mysteriously, then wagged his finger. “Job security.” He faced Turner. Wherever his head moved, his body moved as well, like a clocktower figure. “Torrie will have a mate soon. That effects many changes intriguing to us.”
“Intriguing to Torrie, as well, presumably,” Jurie added, deadpan.
They moved on to a concrete enclosure with a convincing, though small grove of conifers. “No lions or tigers, but we have bears,” Presky said. “Two young males. Sometimes they're out sparring with each other. They are brothers, they like to play fight.”
“Bears, raccoons, badgers,” Turner added. “Peaceful enough critters, virally, at least. Apes, including us, seem to have the most active and numerous ERV.”
“Most plants and animals have their own capabilities in biological propaganda and warfare. War happens only if the populations are pressed hard,” Jurie said. “Shall we hear Dr. Turner's favorite example?”
Turner took them across to a large enclosure containing three rather mangy-looking European bison. Four large, shaggy animals, fur hanging in patches, regarded the human onlookers with ageless placidity. One shook its head, sending dust and straw flying. “Fresh in modern memory, for hamburger eaters anyway: Toxin gene transfer to E. colibacteria in cattle,” Turner began. “Modern factory farming and slaughterhouse technique puts severe stress on the cattle, who send hormonal signals to their multiple tummies, their rumen. E. colireact to these signals by taking up phages—viruses for bacteria—that carry genes from another common gut bacteria, Shigella.Those genes just happen to code for Shiga toxin. The exchange does not hurt the cow, fascinating, no? But when a predator kills a cow-like critter in nature, and bites into the gut—which most do, eating half-digested grass and such, wild salad it's called—it swallows a load of E. colipacked with Shiga toxin. That can make the predators—and us—very sick. Sick or dead predators reduce the stress on cows. It's a clever relief valve. Now we sterilize our beef with radiation. Allthe beef.”
