At midnight, the lighthouse keeper found a stranger dead beneath the lens, with seawater pooling around his polished leather shoes. The keeper touched the cold brass railing, then noticed fresh blood on its underside and a key inside the stranger's fist. Outside, the foghorn sounded once, though its mechanism had been dismantled that morning, and every vessel lay silent in harbor. He climbed toward the lamp, counting stairs until he heard someone above him whisper the dead man's name: Inspector Vale. The lamp ignited without warning, and across the glass appeared a message written backward in salt: Do not trust her.
