At midnight, the lighthouse keeper discovered blood beneath his door. The tide was rising, but no boats approached the island. He followed crimson droplets upstairs, past the crooked family portraits. In the lantern room, his brother lay beside shattered glass. Someone had drawn a compass rose across his bare chest. The keeper recognized its blue ink from yesterday’s anonymous letter. Then the foghorn sounded, though its machinery was still broken. Below, a key turned slowly inside the locked front door. His brother’s voice whispered, “Don’t open it for her tonight.”
