The rain lashed against the windows as the old estate groaned under the storm's relentless assault. Candles flickered in the grand hall, casting eerie shadows upon the bloodstained Persian rug. A hush fell over the guests, their whispered conversations dying abruptly in the tense silence. The butler’s hands trembled as he served brandy, his knuckles white around the crystal glass. A figure lay motionless near the fireplace, a silver letter opener protruding from their back. Gasps erupted as the youngest heir clutched a bloody handkerchief, tears streaking through the grime. The storm howled, rattling the stained glass like a warning of darker revelations to come.
