"I didn't lie, I didn't." The security captain swore to the police with his eyes wide open.
He turned and pointed at Jasper Milton. "I know why you framed me. It must be that you had an affair with Ms. Grace. You were caught red-handed, so you killed him to cover it up."
"Are you a mad dog? Biting anyone you see." Stella Grace snapped angrily.
Jasper became much calmer.
"Please think about it logically. If you are going to kill someone out of emergency, you don't need to prepare poison. With my skills, I can do it easily, would I let you discover me?" Jasper asked.
"Right, now I understand. You must have fed him poison first but then he didn't die, so you stabbed him again. Miss Grace is timid so she screamed."
