The fog shrouded the mansion. A lone figure approached slowly. Shadows danced on ancient walls. Inside, the clock struck midnight. Candles flickered in dim light. A body lay on floor. Blood pooled around the victim. Suspects gathered in the hall. Whispers filled the tense air. Detective arrived with keen eyes. Clues hid in plain sight. Mystery began to unravel now.
