Rain lashed against the tall, arched windows of Blackwood Manor as a single gunshot echoed through the grand library. Detective Vance stepped past the frayed police tape, his weary eyes scanning the polished mahogany floor for any clue. Lord Harrington lay slumped across his massive oak desk, a crimson stain spreading rapidly across his crisp white shirt. The heavy aroma of expensive cigar smoke and metallic blood hung thick in the chilly air of the room. A shattered glass of antique crystal brandy rested beside an open, empty safe built directly into the dark wall. "The killer left no obvious footprints behind," whispered the young constable, nervously clutching his leather notebook with trembling hands. Vance knelt beside the body, carefully examining a tiny golden key tucked discreetly inside the victim's left waistcoat pocket. Six nervous house guests waited quietly down the hallway, each harboring a secret motive for ending the old billionaire's life.
