a heavy beard and powerful arms and a genial manner that communicated confident strength. He had a twin brother, Hollis, identical in all respects except that he kept his face clean-shaven; Arlo’s wife, Leigh, was a Jaxon, Peter’s and Theo’s cousin, which made them cousins, too. Sometimes in the evenings, when he wasn’t standing the Watch, Arlo would sit under the lights in the Sunspot and play guitar for everyone, old folk tunes from a book left behind by the Builders, or go to the Sanctuary and play for the children as they readied for bed—funny, made-up songs about a pig named Edna who liked to wallow in the mud and eat clover all day. Now that Arlo had a Little of his own in the Sanctuary—a mewing bundle named Dora—it was generally assumed that he would serve at most a couple more years on the Wall before standing down to work some other, safer job.
That it was Arlo who had gotten credit for the kill was a matter of chance, as he himself was quick to point out. Any one of them could have been stationed at Platform Six; Soo liked to move people around so much you never knew where you might be on a given night. And yet there was more than luck involved, Peter knew, even if Arlo’s modesty prevented him from saying so. More than one Watcher had frozen in the moment, and Peter, who had never taken a viral close in like that—all his kills had been dozers, shot in broad daylight—couldn’t say for sure that it wouldn’t happen to him. So if there was luck involved, it was everyone’s good luck that it had been Arlo Wilson who had been there.
Now, in the aftermath of these events, Arlo was among a group who had gathered at the gate, part of the resupply detail that would travel to the power station to swap out the maintenance crews and restock supplies. The standard party of six: a pair of Watchers front and rear and in between, on muleback, two members of the Heavy Duty crew—everyone called them wrenches—whose job was to maintain the wind turbines that powered the lights. A third mule, a jenny, pulled the small cart of supplies, mostly food and water but also tools and skins of grease. The grease was manufactured from a mixture of cornmeal and rendered sheep fat; already a cloud of flies had gathered around the cart, drawn by the smell.
In the last moments before Morning Bell, the two wrenches, Rey Ramirez and Finn Darrell, went over their supplies, while the Watchers waited on their mounts. Theo, the officer in charge, took first position, next to Peter; at the rear were Arlo and Mausami Patal. Mausami was First Family; her father, Sanjay, was Head of the Household. But the previous summer, she had paired with Galen Strauss, making her a Strauss now. Peter still couldn’t quite figure that. Galen, of all people: a likable enough guy, but when it came down to it, there was a vagueness about him, as if some essential substance inside him had failed to harden completely. As if Galen Strauss were an approximation of himself. Maybe it was his squinty way of looking at you when you spoke (everyone knew his eyes were bad) or his generally distracted air. But whatever it was, he seemed like the last person Mausami would choose. Though Theo had never said as much, Peter believed that his brother had hoped, someday, to pair with Mausami himself—Theo and Mausami had come up in the Sanctuary together, been released the same year, and apprenticed straight to the Watch—and the news of her marriage to Galen had hit Theo badly. For days after the announcement he’d moped about it, barely uttering a word to anyone. When Peter had finally raised the subject, all Theo would say was that he was fine with it, he guessed he’d waited too long. He wanted Maus to be happy; if Galen was the one to do that, so be it. Theo wasn’t one to talk about such things, even with his brother, so Peter had been forced to take him at his word. But even so, Theo hadn’t looked at him as he’d spoken.
Which was Theo’s way: like their father, he was a man of compact expression who communicated with silence as much as with words. And when, in the days that followed, Peter recalled that morning at the gate, he would find himself
