At midnight, the lighthouse blinked twice, then swallowed its keeper. By morning, seawater pooled beneath his firmly locked bedroom door. The constable found no footprints, only salt carefully arranged clockwise. Inside, Elias Vale lay dead beneath a perfectly dry ceiling. His hands gripped a key carved from ancient black bone. Across the wall, someone had written tomorrow’s predicted tide times. The final hour was circled, though it had already passed. Outside, the harbor bells rang without anyone pulling their ropes. Detective Mara Voss heard a second voice calling inside them. It whispered her name, then asked where she buried him.
