Vending routes in the Swedish far north are paid per slot filled, so Ilse has learned the trick every route driver knows: the loneliest machines sell the strangest things, and nobody audits a machine that always sells out. Then she inherits a route with a machine that isn't on the manifest — a battered Fazer unit in the stairwell of a decommissioned mine shaft, which every month has taken exactly 340 kronor and dispensed nothing, for nine years, and somebody keeps paying.
The men were never buying chocolate. B4 was the lower gallery's coffee round — one man paid for the whole shift each month, and the welded coil was deliberate: a foreman's homemade collection box, because the company's silence money came through a bank and the families' rent didn't. Nine years of coins have been going out the back of the machine, into the pockets of the widows, by hand — and the ledger Ilse mailed keys for isn't a list of the dead. It's the list of who still gets paid, and the machine was the only accountant nobody thought to subpoena.
💡 The engine is a vending machine used as the opposite of what it is — a thing designed to take money and give nothing becomes the most honest institution in the story, which turns a grubby inventory discrepancy into a nine-year criminal conspiracy of decency.
