Fog rolled over the cobblestones as Detective Marlow entered the manor, his breath forming ghostly spirals in the midnight air. The household staff whispered nervously, eyes darting toward the dimly lit hallway where the body lay concealed under the ancient. A shattered vase lay beside the crimson stain, its porcelain shards glinting like tiny mirrors reflecting dread in the silence. Detective Marlow knelt, examined footprints, and noted a single, muddy shoe imprint leading toward the library's forbidden door of secrets. A distant clock struck midnight, echoing through corridors, while a faint perfume lingered, hinting at the victim's final lover perhaps.
