The rain hammered the slate rooftops of Thornwood Manor, each drop echoing like a distant drumbeat in the silent night. Detective Amelia Vance stepped through heavy oak doors, coat dripping, eyes scanning the dim hallway for any disturbance of darkness. The corpse lay sprawled on the marble floor, its face frozen in a scream, a silver letter opener glinting nearby. A scent of jasmine lingered, hinting at a clue, as the storm intensified, sealing the manor’s secrets within its walls.
