Rain hammers hard against the old mansion's tall windows. Thunder rolls across the dark sky outside tonight. Detective Mira Chen arrived to find a body. Wealthy tycoon Harold Ashworth lay dead in his study. The mansion's heavy door was locked tight from inside. Her dark eyes searched every corner of the room carefully. A broken glass sat on the desk near him. Its rim showed traces of bitter, deadly poison residue. The body lay face-down on the cold wooden floor. No blood was found anywhere upon the floor at all. She noticed the desk drawer slightly open and ajar. Strange papers lay scattered across the wooden desk surface. Suddenly a loud knock echoed from the mansion's front door. The butler answered it with his wrinkled, trembling old hands. A young woman stood crying in the pouring rain outside. "I killed him," she said through her tears, trembling. The storm raged on outside, hiding dark secrets within. The killer was still inside the mansion tonight watching.
