Under a moonlit sky, Detective James approached the ancient manor. Inside lived the wealthy patriarch, now brutally, mysteriously murdered. He entered, his flashlight casting long, eerie shadows on the walls. "The game's afoot," muttered James, examining the opulent surroundings. A glistening knife lay on the marble floor nearby. He knelt, studying the weapon for any tell-tale signs. Bloodstains painted a macabre pathway from kitchen to library. James followed, his heart pounding with every step. He pondered silently: Who among them committed this vile act? A family untouched, yet linked by deception's wicked threads unraveling now.
