“I think the closest analogue would be bees,” Michael had said. During their long days on the mountain, Peter had given everyone Lacey’s files to read; the group had spent many hours in debate. But ultimately it was Michael who had advanced the hypothesis that pulled all the facts together.

“These Twelve original subjects,” he went on, gesturing over the files, “they’re like the queens, each with a different variant of the virus. Carriers of that variant are part of a collective mind, linked to the original host.”

“How do you figure that?” Hollis asked. Of all of them, he was the most skeptical, pressing on every point.

“The way they move, for starters. Haven’t you ever wondered about that? Everything they do looks coordinated because it is, just like Olson said. The more I think about it, the more this makes sense. The fact that they always travel in pods—bees do the same thing, traveling in swarms. I’ll bet they send out scouts the same way, to establish new hives, like the one in the mine. And it explains why they take up one person out of ten. Think of it as a kind of reproduction, a way of continuing a particular viral strain.”

“Like a family?” Sara said.

“Well, that’s putting it nicely. We’re talking about virals here, don’t forget. But yes, I suppose you could look at it that way.”

Peter remembered something Vorhees had said to him, that the virals were—what was the word? Clustering. He related this to the group.

“It follows,” Michael agreed, nodding along. “There’s very little large game left, and almost no people. They’re running out of food, and running out of new hosts to infect. They’re a species like any other, programmed to survive. So pulling together like that could be a kind of adaptation, to conserve their energy.”

“Meaning … they’re weaker now?” Hollis tendered.

Michael considered this, rubbing his patchy beard. “‘Weaker’ is a relative term,” he replied guardedly, “but yes, I’d say so. And I’ll go back to the bee analogy. Everything a hive does, it does to protect its queen. If Vorhees was right, then what you’re seeing is a consolidation around each of these original Twelve. I think that’s what we found at the Haven. They need us, and they need us alive. I’ll bet there are eleven more big hives like it somewhere.”

“And what if we could find them?” Peter said.

Michael frowned. “I’d say it was nice knowing you.”

Peter leaned forward in his chair. “But what if we could? What if we could find the rest of the Twelve and kill them?”

“When the queen dies, the hive dies with it.”

“Like Babcock. Like the Many.”
