Rain slicked the old road. Colonel Mustard lay quite dead. A dagger gleamed in mud. His cravat was still tied. Footprints marred the wet ground. Miss Scarlet shivered nearby. Her coat was torn somewhat. Professor Plum stroked his beard. He gazed at the still form. The air felt quite heavy. Inspector Clouseau surveyed all. His small notebook was ready. A new case had begun.
