At midnight, the lighthouse bell rang beneath a cloudless sky. Nobody had touched its rope since Captain Vale drowned yesterday. But tonight, someone answered its toll with a single gunshot. Detective Mara Voss found the keeper slumped beside untouched breakfast. His coffee steamed gently, though his skin was stone cold. The pistol lay nearby, wrapped carefully inside yesterday's folded newspaper. Across the floor, three damp footprints ended at empty air. Then the dead keeper's radio crackled beneath her gloved hand. A woman's voice whispered, “Don't let him ring the bell.” Behind Mara, the lighthouse bell began its slow thirteenth toll.
