Detective Jay is typing: "It all started on a cold winter night. Thin air and a blue rose are the only clues. The truth will soon be revealed. But I deceived myself. I close my eyes and let sin eat me alive. Everything in the story, a murder happened in ..................... overnight. Detective Jay and his assistant Yu saw a man looking around when they were looking at the body at the scene, so they caught up with him. Unfortunately, the man ran away.
