The cold autumn rain hammered relentlessly against the tall stained glass windows of Blackwood Manor as lightning split the sky. Inside the sprawling estate, elderly Margaret Ashworth lay motionless at the bottom of the grand marble staircase, eyes fixed upward. Her long silver hair fanned out across the cold floor, and a single crimson drop had stained her pale lips. The faithful housekeeper had discovered the body at midnight, her terrified screams waking every sleeping soul within those ancient walls. Detective Sarah Chen arrived two hours later, her sharp eyes carefully noting every detail of the gruesome scene before her. Something about the position of the corpse troubled her deeply, for the limbs seemed carefully arranged rather than naturally fallen. A crystal decanter of expensive brandy lay shattered nearby, its dark amber contents slowly pooling across the polished marble floor. Chen knelt beside the body and noticed something clutched tightly in the dead woman's cold, unyielding fingers: a gold locket. Six nervous suspects now gathered in the candlelit drawing room, each claiming innocence while casting suspicious glances at one another. The victim's vast fortune, estimated at nearly forty million dollars, had provided more than sufficient motive for murder most foul. When Chen revealed the locket's faded photograph, nobody in the room would admit to ever having known the young man. The storm raged on outside, utterly indifferent to the darkness that had descended upon the shadowed halls of Blackwood Manor.
