The fog rolled thick over Blackwood Manor as Detective Sarah Chen stepped from her car into the cold night air. Ahead, the manor's tall windows glowed amber against the darkness, promising warmth but concealing something far more sinister waiting inside. A young officer greeted her at the door, his face pale beneath the flickering porch light, his hands trembling visibly. He had found the body an hour ago, he explained, discovered by the housekeeper during her final rounds before bed. Sarah followed him through the cold marble foyer, past portraits whose painted eyes seemed to track her every careful step. The study door stood open, and yellow police tape stretched across the frame like a warning she could not ignore. Inside, old Lord Blackwood lay sprawled across his desk, a letter opener buried deep between his shoulder blades, glinting silver. His gray eyes remained open, frozen in an expression of genuine surprise, as though he had trusted his killer completely. The room told its own story: a toppled whiskey glass, scattered papers, and the faint smell of expensive pipe smoke. But something was wrong here, something the young officer had missed entirely in his shock at finding the dead body. Sarah knelt beside the desk, studying the dust on the tall bookshelf, where one clean gap betrayed a missing volume. The killer had taken something from this room, and that single small detail changed everything she thought she already knew. Somewhere in this grand house, among the grieving family and loyal staff, a murderer waited patiently for her to arrive. Sarah pulled on her gloves slowly, took a deep breath, and stepped across the threshold into the dead man's world.
