The old house stood silent. Rain lashed against the windows. A cold wind howled outside. Mrs. Gable held her breath. Her flashlight cut the gloom. She checked the locked doors. A foul smell lingered weakly. It came from the study. Her heart pounded in fear. The heavy door stood ajar. She pushed it open slowly. A figure lay on floor. Dark liquid pooled beneath him. Sir Reginald Thorne lay dead. His eyes stared at ceiling. Unseeing, they held pure terror. Mrs. Gable gasped in shock. Her old hands began shaking. She dropped her trembling phone. It clattered loudly on floor. A distant siren would soon sound. Doom had arrived tonight clearly.
