Rain lashed the window pane. Lord Ashley lay completely still. A dagger pierced his chest. Spilled brandy dripped onto mahogany. The grandfather clock ticked slowly. Detective Miller opened the door. He stepped into the room. Fresh footprints marked the floor. Miller knelt beside the corpse. The flesh felt very cold. One clue grabbed his attention. A golden key rested nearby. The study held many secrets. The hunt had just begun.
