A chilling scream shattered midnight's silence, drawing Detective Harper's weary footsteps toward the ominous ancient mansion perched above fog-drenched cliffs. Torches flickered along cracked walls, casting dancing shadows that whispered of betrayal, secrets, and cold blood buried beneath marble floors. Harper's gloved hand brushed the mansion's grand oak door, silent, hesitating before pushing it open toward smells reminiscent of fear. Inside, a shattered, crystal chandelier glittered ominously above the sprawling foyer, its prisms scattered across crimson-stained marble like fallen tears. Blood pooled beside a luxurious Persian rug, its rich patterns smudged and stained beneath the lifeless body of Madame Delacroix. Harper's eyes darted from broken glass to disturbed footprints, piecing together murder's silent puzzle with unwavering determination amid growing dread.
