Night duty archive — reopened, autumn 1958.
The Lime Tree, a boarding house on the edge of town. Five deaths in five years. Five full guest lists, five bodies, five times no conviction at all. The files were shut, the house stayed open, and the lamp above the desk went on burning.
Tonight all five folders are on your desk. In each one: a plan of the scene and the statements of everyone present. Where a person was is fixed — and so is where they said they were. Your work: set out on each plan where everyone stood. The last free square is the victim's. Whoever shares an area with the victim is the killer.
Five plans. Five killers. And one name that keeps coming back, in the margin of every file. Watch for it. Write it down. You will need it.
Five plans, five killers — all of them guests, all of them convicted on your work. But five different killers do not plan the same night five times over. Somebody gave them the keys, the times, the names. Your evidence file lies open on the table: five exhibits, one small and tidy hand. Lay them side by side and fill in the report.
