At midnight, the lighthouse blinked twice, then never blinked again. Detective Mara Vale arrived before the retreating tide revealed everything. The harbor master smashed the locked door with his lantern. Inside, the keeper sat dead beside his untouched birthday supper. His watch ticked steadily, though someone had removed its hands. Across the table lay three keys, each stained with salt. Only one opened the lighthouse, according to the harbor master. But the door had been bolted from within since dusk. Mara noticed wet footprints leading upstairs, never coming down again. The final print ended beneath a portrait of her father. Her father had drowned here twenty years earlier, officially alone. Behind the glass, a handwritten message read: “He never drowned.”
