The rain fell hard against the old mansion windows. Detective Cole stepped inside, boots squeaking on polished marble. A single lamp flickered, casting long shadows down the hall. The butler stood rigid, his face pale as fresh snow. "She’s dead," he whispered, voice trembling like autumn leaves. Cole followed him upstairs, each step creaking under his weight. The bedroom door stood ajar, revealing a scene of chaos. Blood splattered the walls like crimson paint on canvas. A woman lay still, her silk gown stained with dark red. Her eyes stared blankly, reflecting the dim candlelight above.
