Clicking download, Mira felt silly and thrilled, like an explorer opening a trapdoor. The files arrived in a neat folder. The seed was a short string of letters that when fed into an old synthesizer in her basement hummed a tune she half-remembered from childhood. The map unfolded into a photograph of a tiny café she used to pass without noticing. The clock file contained a recording: faint traffic, a dog barking, someone humming the same tune.
