The last shift at the Elmore Stamping Plant was March 14th. The shift started at six and ran until two-thirty in the afternoon, which was the same as any other shift for the past forty years, except for the fact that it ended the plant. Tom had worked the line for twenty-two years and had spent two weeks trying to decide whether to take something from the plant as a keepsake or to leave empty-handed. He had decided, by the last day, to leave empty-handed, but standing at his station at the end of the shift he picked up a stamping die anyway and put it in his bag. The closing ceremony, if it could be called that, was a short speech from a plant manager who had been there for four years and who thanked everyone for their service, which was the correct thing to say. Tom had expected to feel something more specific than what he felt, which was a general heaviness with no particular object. He had prepared himself for the loss of the job and the pay and the structure. He had not prepared himself for the loss of the specific sound the line made, which he had stopped hearing years ago and only now noticed was gone. He drove home on surface streets instead of the highway, which added eleven minutes. He still had the die in his bag. He did not take it out when he got home. He put the bag in the closet and made coffee and sat at the table and looked at nothing specific for twenty minutes, which is what he did on any weekday afternoon when his shift ended.

Dr. Miriam Osei could identify, from a sample of soil on a person's shoes, which part of which city they had walked through in the past forty-eight hours, assuming they had not cleaned the shoes. This was not a trick. It was a skill she had developed over twenty years of forensic pedology and it had resulted in four peer-reviewed papers, two court cases, and a small but dedicated following among criminologists who were not sure how to cite her work in ways that would survive cross-examination. The practical application was narrower than people assumed. She could tell you the type of soil, the likely deposit location, the mineralogical composition, and often the specific district of a city if she had reference samples. She could not tell you why the person had been there. This distinction mattered enormously in courtrooms and mattered very little to the people who contacted her after reading a magazine profile, asking her to find missing family members by their shoes. She had not taken any of those cases. She had thought about them, standing in her lab over samples from other contexts, considering what it meant to know where something had been without knowing why. She had written about this in the acknowledgments section of her third paper, which was not standard practice. The editor had asked her to remove it. She had revised it into a single sentence that she knew only she understood, and it had stayed.
