The rain began before midnight. By dawn, someone was dead. Inspector Vale arrived at six. The manor stood above Blackwater. Its windows reflected nothing living. Inside, a clock kept chiming. Nobody remembered winding it lately. Lord Harrow lay beside it. Blood darkened his white collar. His right hand clutched ash. The library door was locked. The key remained inside, untouched. One footprint marked the carpet. It pointed toward the fireplace. A woman’s voice broke silence. “He wasn’t alone last night.” Vale turned toward the doorway. She was Harrow’s younger sister. She held his wedding ring. Blood glittered along its edge.
