Nine Letters, No Signature

The first letter arrived on a Tuesday, slipped beneath Harlan Cole's door with no stamp and no name. It confessed, in careful blue ink, to the murder of a man Harlan had never heard of, in a town two counties over, at a date three weeks in the future. He almost threw it away. Forty years on the force had taught him that most anonymous letters were the work of the lonely and the drunk. But the details were too precise—the make of the car, the color of the victim's front door, the exact minute the clock would stop. The second letter came the next morning. By the ninth, Harlan had a map of a killing laid out like a train schedule, and eleven days to decide whether a confession written before the crime was a warning, a boast, or a dare. He poured his coffee, spread the letters across the table, and did the only thing he still knew how to do. He began to read them as a case.
