One week, someone identified a building on the edges of town marked in the packet as a possible cache. It was a flat, low structure with rusted vents and an address that no longer appeared on the city’s newer maps. A group went, armed with a flashlight, a map, and a copy of the packet. They came back with a box of canned peaches, a spiral-bound field manual damp but legible, and an old radio with a dial that scratched like gravel. They also returned with a story: there had been another person there, an older woman who’d been living off the edge of maps. She had kept a ledger of births and small deaths, of bargains struck and favors remembered.
