The rain fell like knives. Detective Mara Vance arrived. The mansion loomed above her. Inside, a body waited. Lord Ashworth lay quite dead. His eyes stared at nothing. A knife protruded from him. Blood pooled on marble floors. The staff stood in silence. Each face hid something dark. Mara knelt beside the corpse. Cold had settled in deep. Death had come hours ago. Yet the window was open. Someone had left quite recently. Her flashlight caught something shiny. A button lay near blood. Gold thread, torn from clothing. The killer had been careless. Or wanted to be found. Thunder rolled across black clouds. The storm mirrored her thoughts. Everyone here had secrets buried. Mara would dig them up. Tonight, the truth would surface. One of them was lying. Murder always leaves a witness. Silence, in this house, spoke.
