Kira turned her attention to the shelves, trying to deduce from their condition, and from the placement of the footprints, exactly what the scavenger had taken. The main concentration of prints was, predictably, in the corner where the generators had been displayed, but the more she looked, the more she saw a deviation in the pattern: He had taken at least two trips to the opposite side of the store, one slow as if he were looking for something, and one firm, the prints deeper, as if he’d been carrying something heavy. She glanced over the shelves, her eyes sliding past dusty plastic phones still tethered to the metal frames, past slim notebook computers and tiny music players like Xochi used to collect. She followed the trail carefully through the rubble on the floor, ending at a low, empty shelf near the back. He’d definitely taken something. Kira bent down to brush away the dirt from the shelf tag, and struggled to decipher the weathered writing: HAM. Ham? No electronics store would sell ham. She peered closer, picking out the faded, filthy word that followed: RADIO. HAM radio, the “ham” all in capital letters. Another acronym, like IT, that she’d never come across before.

Computers, generators, and now radios. Her mysterious scavenger was putting together quite the collection of old-world technology—and he was obviously an expert, as he’d known precisely what the thing on this shelf had been without having to clean up the tag first like she had. More than that, though, he’d taken some very specific equipment from the ParaGen offices, which couldn’t possibly be a coincidence; he wasn’t just grabbing certain kinds of technology, he was grabbing specific pieces of it. He was gathering old computers from ParaGen, and the generators to be able to access them. And now he was gathering radio systems, but who was he trying to call?
