Rain lashed against the grand windows of Blackwood Manor, creating an unsettling, mournful ambiance throughout the night. Detective Inspector Davies arrived, pulling his trench coat tighter against the chilling, persistent, watery assault. The housekeeper, Mrs. Higgins, nervously wrung her hands, offering a shaky, apprehensive greeting to the weary investigator. A single crimson stain bloomed dramatically on the Persian rug, immediately demanding a thorough, careful examination. Lord Blackwood lay sprawled upon the opulent chaise lounge, a priceless antique dagger protruding from his chest. Silent, horrified guests lingered in the hallway, each exhibiting a distinct, subtly frightened, and guarded expression. The local constabulary had secured the perimeter, establishing a surprisingly efficient, meticulously organized, initial cordon. A delicate, antique music box sat open nearby, playing a hauntingly familiar, melancholic, forgotten tune. Davies surveyed the lavish, decaying room, realizing this case was destined to be exceptionally complex and strange.
