Rain lashed against the ancient windows of Blackwood Manor, creating a mournful, unsettling atmosphere throughout the night. Detective Inspector Davies arrived, shaking off the cold drizzle and stepping cautiously onto the moss-covered drive. The assembled guests, a collection of eccentric relatives and unsettling acquaintances, seemed deeply preoccupied with their own anxieties. A single, crimson stain marred the polished mahogany floor within the grand ballroom’s immediate vicinity. Lord Blackwood lay sprawled beneath a priceless chandelier, a silver letter opener protruding from his chest with gruesome precision. Forensics immediately began meticulously documenting the scene, searching for any overlooked clues or subtle discrepancies. The local constable, a nervous young man named Miller, offered a hesitant, almost bewildered, explanation of the events. A fragile, antique music box sat open on a nearby table, playing a hauntingly familiar, melancholic tune. Whispers circulated amongst the distraught relatives regarding a decades-old family feud and a bitter inheritance dispute. Davies surveyed the room, his sharp eyes taking in every detail of the opulent, yet tragically disturbed, setting.
