The cold moonlight filtered through the dusty curtains, casting long shadows across the victim lying still upon the velvet rug. A single crimson stain bloomed outward from his chest, marking the silent end of a very long and bitter feud. I knelt beside the body, checking for any lingering pulse, but the man had clearly parted from this world tonight. The heavy scent of metallic blood filled the stagnant air, mingling with the bitter aroma of a fading expensive cigar. Somewhere in the darkened hallway, a floorboard creaked loudly, signaling that the killer had not yet fled the grand manor.
