The rain hammered against the windows of Blackwood Manor as the clock struck midnight, echoing through the empty halls. Elizabeth Whitmore clutched her silk shawl tightly as she descended the grand staircase, her heels clicking sharply on the marble. A faint scent of lavender lingered in the air, mingling with the metallic tang of something sinister. The door to the study stood ajar, revealing a single lantern casting eerie shadows across the oak floor. A shattered crystal decanter lay near the fireplace, its contents absorbed by the Persian rug. A muffled gasp echoed from the corner as Elizabeth’s breath caught in her throat. The fireplace’s embers still glowed, casting flickering light upon the crimson stain spreading across the Persian carpet.
