Moonlight seeped through shattered windows, illuminating crimson stains that spoke of ruthlessness, whispering secrets hidden within icy frozen midnight air. Detective Camille Hart stepped delicately between bodies, noting peculiar bruising patterns, while storm winds rattled loose ancient beams overhead unpredictably. Blood pooled around shattered glass, reflecting grim fragments of despair through ancient skeletal window frames like malevolent stained glass mosaics. A single pearl earring lay abandoned on cracked marble floor, its twin conspicuously missing beside the corpseās outstretched, trembling hand. Detective Hart felt nerves prickle as distant church bells tolled midnight, chilling her bones with ominous portent and rising dread. Flickering candles sputtered, nightmarish shadows danced grotesquely across cold walls, transforming innocent tapestries into silent witnesses of unfolding sinister intrigue. Her gloved hand instinctively brushed concealed badge as she braced herself, determined to expose the merciless killer lurking within halls.
