The old lighthouse stood silent above the cliffs while heavy fog swallowed every distant sound from restless sea below tonight. Detective Mara Quinn pushed open the rusted iron door and discovered the keeper lying motionless beside his shattered brass lantern. Blood pooled darkly across cold stone floor, glinting faintly beneath the flickering beam that still turned without any living guidance. Outside, waves crashed violently against jagged rocks as gulls screamed, yet no footprints marked the wet sand beyond the tower. Quinn knelt carefully beside the body, noticing a torn page clutched tightly in his cold stiff fingers despite death's grip. The scribbled message warned of betrayal at midnight, naming no killer but promising that another victim would soon follow inevitably.
