Caleb was eating as he spoke, gnawing off bites of hardtack and washing them down with gulps of water. Well, everything had been normal, Caleb explained, until about six days ago, when Zander had begun to act… odd. Very odd. Even for Zander, which was saying something. He didn’t want to go outside the fence, and he wasn’t sleeping at all. All night long he’d be up pacing the control room, muttering to himself. Caleb thought it was just too much time at the station, that when the relief crew showed, Zander would snap out of it.

“So then one day he announces we’re going out to the field, and tells me to get the cart packed and ready. I was sitting here eating my lunch, and he just marches in and announces this. He wants to swap out one of the governors in the west section. Okay, I say, but what’s the big emergency? Isn’t it a little late in the day to be going to the field? He’s got this crazy look in his eyes, and he smelled bad. I mean, he stank. You feeling okay, I ask him, and he says, Just get your gear, we’re going.”

“When was this?”

Caleb swallowed. “Three days ago.”

Theo leaned forward in his chair. “You’ve been outside three days?”

Caleb nodded. He’d finished off the last of the hardtack and started on a dish of soybean paste, scooping it out with his fingers. “So we ride out with the jenny, but here’s the thing. We don’t go to the west field. We go to the east field. Nothing’s worked over there for years; they’re all dead sticks. And it takes forever to get there, two hours with the cart at least. It’s past half-day, we’re cutting it close as it is. I’m like, Zander, west is that way, buddy, what the hell are we doing out here? Are you trying to get us killed? So we get to the tower he says he wants to fix, and the thing’s a rust bucket. Completely backblown. I can see that from the ground. No chance swapping the governor’s going to do anything. But that’s what he wants to do, so I haul my ass up the ladder and set the winch and start stripping out the old housing, working as fast as I can. I’m thinking, Okay, this doesn’t make a lot of sense, as far as I can tell we’re risking our necks for nothing, but maybe he knows something I don’t. Anyway, that was when I heard the scream.”

“Zander screamed?”

Caleb shook his head. “The jenny. I’m not kidding, that was exactly what it sounded like. I’d never heard anything like it. When I looked down she’s just keeling over, going down like a bag of rocks. It takes me a second to figure what I’m seeing. It’s blood. A lot of it.” He wiped his greasy mouth with the back of his hand and pushed the empty dish of paste aside. “Zander always said this stuff tasted like balls. I was like, When did you eat balls, Zander, like I really want to know? But after three days, it’s really not half bad.”

Theo sighed impatiently. “Caleb, please. The blood-”

He took a long swig of water. “Right, okay, so. The blood. Zander’s kneeling by her and I yell, Zander, what the hell happened? When he gets up I see he’s stripped to the waist, he’s got a blade in his hand, and there’s blood all over him. Somehow I missed the signs. I’ve got about five seconds before he comes up the ladder for me, too. But he doesn’t. He just sits down at the base of the tower, in the shade of one of the struts, where I can’t see him. Zander, I yell down, listen to me. You got to fight this thing. I’m all alone up here. I’m thinking that maybe if I can get him to snap out of it long enough, I can make a run for it.”

“I don’t get it,” Alicia said. “When would he have gotten infected?”

“That’s the thing,” Caleb went on. “I couldn’t figure that either. I’d been with him just about every minute of the day.”

“What about at night?” Theo offered. “You said he didn’t sleep. Maybe he went outside.”

“I suppose that’s possible, but why would he? And plus, he didn’t really look any different, apart from the blood.”

“What about his eyes?”

“Nothing. No oranging at all, from what I could see. I’m telling you, it was weird. So I’m stuck on the tower, Zander’s at the bottom, maybe taken up and maybe not, but either way it’s going to get dark eventually. Zander, I yell, look, I’m coming down, one way or the other. I’m not armed, all I’ve got is the wrench, but maybe I can brain him with it and get away. I’ve also got to get the key from him somehow. I can’t see him from the ladder, so when I’m about three meters from the bottom I decide what the hell, I’m just going to jump. I’ve already tipped my hand, but I figure I’m dead anyway. I drop and come up with the wrench ready to swing. But it’s gone. Snatched right out of my hand. Zander’s right behind me. That’s when he says to me, Go back up.”

“Go back up?” This was Arlo.

Caleb nodded. “No kidding, that’s what he said. And if he was flipping, I still couldn’t tell. But he’s got the blade in one hand, the wrench in the other, there’s blood all over him, and without the key there’s no way I’m getting back inside the station. I ask him, What do you mean go back up, and he says, You’re safe if you go back up the tower. So that’s what I did.” The boy shrugged. “That’s where I was for the last three days, until I saw you on the Eastern Road.”

Peter looked at his brother; Theo’s expression indicated he didn’t know what to make of Caleb’s story either. What had Zander intended? Had he already been taken up or not? It had been many years, and not in living memory, since anyone had directly witnessed the effects of the infection’s early stages. But there were plenty of stories, from the early days especially, the time of the Walkers, of bizarre behaviors-not just the blood hunger and spontaneous disrobing that everyone knew to be a sign. Strange utterances, public speechmaking, manic feats of athleticism. One Walker, it was said, had broken into the Storehouse and actually eaten himself to death; another had killed all his children in their beds before setting himself aflame; a third had stripped naked, ascended to the catwalk in full view of the Watch, and recited, at the top of his lungs, both the entire Gettysburg Address-there was a copy of it hanging on the wall in one of the classrooms in the Sanctuary-and twenty-five verses of “Row, Row, Row Your Boat” before hurling himself over, twenty meters to the hardpan.

“So what about the smokes?” Theo asked.

“Well, that’s the funny thing. It was just like Zander said. There weren’t any. At least none that came close. I could see them once in a while at night, moving out in the valley. But they pretty much just left me alone. They don’t like to hunt in the turbine fields, Zander always thought the movement screwed them up, so maybe that’s got something to do with it, I don’t know.” The boy paused; Peter could see the weight of his ordeal finally catching up with him. “Once I got used to it, it was actually kind of peaceful. I didn’t see Zander after that. I could hear him, scuffling around at the base of the tower. But he never answered me. By then I figured my best chance was to wait for the relief crew to show up and try to get away.”

“So you saw us.”

“Believe me, I yelled my lungs out, but I guess you were just too far away to hear me. That’s when I realized Zander was gone. The jenny, too. The virals must have dragged it off. By then I only had a hand of daylight at the most. But I was out of water, and there was no way anyone was coming to look for me in the east field, so I decided to climb down and make a run for it. I got to within maybe a thousand meters when suddenly the smokes were just everywhere. I thought, That’s it, I’m meat for sure. I hid under the base of one of the towers and pretty much waited to die. But for some reason, they kept their distance. I couldn’t tell you how long I was under there, but when I looked out they were gone, not a smoke in sight. By then I knew the gate was closed, but I guess I just thought I could get inside somehow.”
