The oppressive silence of the grand old library felt heavier than usual on this storm-laden evening, truly concealing dread. A lone figure, Mr. Abernathy, cautiously approached the ominous flickering glow within the forbidden east wing tonight. He pushed the heavy oak door open slowly, revealing a most ghastly scene that instantly froze his very soul. Lord Ashworth lay motionless upon the expensive Persian rug, his eyes wide with a terror none could comprehend. A shattered crystal decanter lay nearby, its spilled amber contents staining the intricate tapestry under pale, ethereal moonlight. No visible sign of forced entry marred the room, suggesting the killer was perhaps known to his unfortunate victim.
