Rain battered the glass window. Inside, the study was cold. A single lamp flickered dimly. Lord Harrington sat very still. His crimson blood pooled slowly. It stained the expensive rug. A broken glass lay nearby. The grandfather clock chimed midnight. The heavy wooden door creaked. Detective Miller stepped inside quietly. He pulled off wet gloves. The dead man looked surprised. A golden key was missing. Only one person knew why.
