Murder Agreement

"Yes, Officer, you are correct!" Liu Pengfei confessed with his head hung low, "I saw it in a movie, or some drama. It was a Korean one. It was a ‘murder exchange case!’ I felt that the method suited me well, so I used it to plan my revenge!"

 "What?" Zhao Yu thought. He paused, "Murder Exchange Case? What? How come I’ve never seen it?"

 "Yes!" Liu Pengfei continued, "I wanted to kill my wife, Jian Wenli, for a long time! After doing some research, I found Lin Meifeng, and signed a murder contract with her. I agreed to help her kill Yu Zhigen, and she help me kill Jian Wenli!!"

 Ah? Zhao Yu could not help but be stunned! He finally understood the so-called "murder exchange." So that was what it was?

 "Ten years ago, on July 12th, not only was it pouring rain, but it was also when Lin Meifeng’s cousin was in labor, so she had a good alibi! So…I acted!"

 "Did you get Yu Zhigen’s key from Lin Meifen?" Miao Ying asked.
