“Damn.” McReady rubbed her eyes. They were paler in color than Benny had expected, less of the intense dark brown of the face in the Teambook photo and more of a dusty burned-gold hue. “The one upside to working in total isolation is that it focuses your concentration.” She nodded at the stacks of containers and heaps of bags. “See those boxes? Eleven tons of a powdered version of the mutagen, boxed to make it easier to transport and store. But you do not want to get any of it in a mucous membrane. Any moisture will activate the bacteria, and that starts the worms hatching.” She laughed. “Those worms are something else. Industrious and clever little buggers. Once they become active in a walker, all the walker’s tissues become softer, more pliant. This is why the R3’s are able to move so much more quickly.”
“What’s in the bags?” asked Nix. “Is that the cure? Is that Archangel?”
“Yes. We have 968,000 capsules as of yesterday’s count. They have enough supplies back at Sanctuary to make a million doses a month.”
“We can save the world,” whispered Nix.
McReady rubbed her eyes. “Yes,” she said hoarsely. “Yes, we can.”
They stared at the bags. Benny felt like the floor was tilting under him.
Lilah cut into the silence. “The mutagen doesn’t just make the zoms faster. They got smarter, too.”
Benny nodded. “One of them picked up a stick and hit me with it.”
“Mm,” McReady said diffidently. “The appearance of increased intelligence is nothing magical. From the initial infection, the parasites feed tiny amounts of oxygen to the brain as well as other key proteins and chemicals to the nervous system. That means the brains never die a complete death as they do in ordinary mortality. The parasites have to preserve some of the cranial nerves in order for the host body to walk, grab, eat, chew.”
“But they don’t need to eat,” said Benny. “Everyone knows that.”
“Sure they do. When they don’t or can’t, they go into a deeper stasis. They stop moving, stop expending energy. It’s like a super-amplified version of the hibernation state, similar to that of a ground squirrel. The squirrel’s metabolic rate drops to one percent, but with the walkers it’s down to one thousandth of one percent. They are dead by any standard clinical model, but not in point of fact. The parasites can’t let the host body completely decay, otherwise it’s of no value as a vector for spreading the disease. So the process of necrosis is slowed to an almost negligible level. However, when they do eat, the food they consume is broken down by enzymes at an incredibly slow rate. It might take them months or even years to fully digest whatever protein they’ve consumed. All the while the parasites are being fed.”
“Why don’t people know this?” asked Nix.
“People do,” said McReady. “Everyone in the American Nation knows this. It’s taught in school. I’m surprised you don’t know it.”
“That’s not the kind of thing they teach us at home,” said Nix.
“Pity,” sniffed McReady. “Knowledge is power. Lack of knowledge is suicide.”
Benny did not reply to that. He asked, “I’m confused about a few things. Like, why did that man, Mr. Price, write what he wrote?”
“Price spent his life designing bioweapons. Airborne Ebola and a form of tuberculosis used for assassinations, that sort of stuff. He was Dr. Death for thirty years before the Fall. I guess he thought he had a lot to answer for. He probably did have a lot to answer for. Maybe not Reaper, but enough other monsters.”
“Why did you think Joe was here to kill you?”
She almost smiled. “When I saw Joe, I thought that Jane Reid or one of her masters figured I’d gone off the reservation, maybe gone crazy and joined the reapers. Whatever. Generally, if you see Joe Ledger show up pointing a gun at you, I guess you start reexamining your conscience.”
“I’m not an assassin,” said Joe mildly.
“I’m sure that was never on your business card,” was McReady’s cold reply.
“There’s something else,” interrupted Benny. “You said that there were R3’s in Washington and then some around here… but Nix and I saw some fast zoms near where we live, up by Yosemite National Park, in Mariposa County.”
“Drifters,” said McReady. “Probably wild boars spreading the mutation.”
“But what about the boars that attacked Lilah in Nevada, and the R3’s Nix and Lilah fought? Wild boars don’t live in deserts.”
McReady grunted. “I… don’t know.” She looked at Joe. “Could Reid have been—?”
“Reid doesn’t have the D-series notes. I gave her some samples of the mutagen, but she didn’t know what to do with it. And even if she did, she wouldn’t try it on walkers in the wild. She’s not a genius, but she’s not suicidally stupid.”
“Reapers,” said Lilah.
Everyone looked at her. McReady said, “Only if they had the missing notes and a good scientist. A chemist, a molecular biologist, an epidemiologist. Someone who understands the kind of science we’re talking about.”
“Could the reapers have someone like that?” asked Nix. “I mean… they’re religious nuts.”
“They’re religious nuts now,” said Benny. “Who and what were they before they joined the Night Church?”
It was an ugly question, and the answers seemed to scream at them.
“I have a question,” said Nix into the silence. She nodded to the wall of plastic containers. “You made all this. Why? I mean… if you were trapped, if you thought you’d never get out, why did you—?”
McReady’s eyes softened for the first time. “Because there’s always hope, isn’t there?”
“Is there?” asked Lilah, her voice strained. “Hope for whom?”
“For everyone. Even if we died in here, there was always the chance someone would find us and find the stores of Archangel. And — I thought that my notes, my research, was in the hands of Jane Reid’s people at Sanctuary. I thought by now they’d have mass-produced a million tons of it. They should have. Once the parasites are active again, the process of decay kicks in, and the swine bacteria accelerates it. The walkers will become more dangerous, that’s a given, but only for a week or so. Then the decay will have weakened their connective tissues. They’ll start falling apart.”
“The zoms outside looked pretty spry,” said Joe. “I had to gun ’em down.”
“No, that’s the natural mutation from the pigs. They’re faster, but the decomposition is still slow. We figure it will take forty-eight to sixty months for those walkers to fall. Our synthetic version of the natural mutagen — the one we developed before we evacuated Hope One — is different. You get a very fast walker for two or three days, and then you get one that’s slow and awkward, and then you have a pile of meat and bones.”
“What about someone who’s infected but not dead?” asked Lilah. “Would Archangel save them… or kill them?”
“You have to give them Archangel before they’re exposed to the mutagen. At least a full dose. Two capsules. Luckily, it kicks in fast, but without Archangel in their system, the mutagen will only kill them faster.”
“And with Archangel?” demanded Lilah.
“Depends on what you’re asking. If someone takes Archangel and dies, they don’t reanimate.”
“My brother died and he didn’t reanimate,” said Benny.
McReady nodded. “Same thing happened to a few people here. We think that’s a side effect of the mutation. As the new version of the pathogen spreads, some people are developing immunity to the reanimative aspects of the plague. Our computer models indicate that in time — maybe ten or fifteen years — as many as one percent of the population will develop immunity. While that sounds hopeful, it isn’t an answer. You say your brother didn’t reanimate? Then count yourself lucky.”
