The rain fell in relentless sheets upon the old, decaying Hastings Manor. Detective Miles arrived with a weary sigh and a heavy heart. The butler, a skeletal man named Graves, opened the creaking front door. His face was a pale, emotionless mask in the dim foyer light. "The body is in the library, sir," he whispered with chilling calm. Miles wiped his wet shoes on the threadbare rug, observing everything silently. The house felt unnaturally cold, steeped in shadows and unspoken secrets. He followed the silent butler down a long, darkly paneled hallway. A single portrait of a severe-looking woman watched their progress with disdain. They finally reached a pair of ornately carved mahogany library doors. Graves pushed them open to reveal the dreadful scene inside. Lord Ashworth lay sprawled on the Persian rug near the fireplace. A single, ornate letter opener protruded from his motionless chest. A look of sheer surprise was frozen upon his aristocratic face. A half-finished glass of brandy sat undisturbed on the desk. Miles noticed the windows were all securely locked from the inside. "Who found the body, and at what precise time, Graves?" The butler’s eyes shifted nervously toward the grand staircase above. "That would be Lady Ashworth, sir, just before the clock struck ten."
