On a rainy night in the back alley of the city concert hall, the red and blue police lights intertwined, breaking the Bach melody that should have been lingering, and also unveiled the prelude to the third serial murder. The chief cellist died tragically on a wet asphalt road, with a sharp wound on his neck. He was holding a violin bow that did not belong to him, and a strange gelatinous substance remained in his ears. This was exactly the same as the previous two murders of an opera singer and a sound engineer, with a strong sense of ritual but no clear motive.
Lin Jing, an on-site behavior reconstruction expert specially hired by the General Administration, appeared in the cordon wearing a dark gray cashmere coat. She wears an invisible hearing aid and relies on vision and skin vibrations to perceive the world, but she has on-site insights beyond ordinary people. She glanced over the body covered with white cloth, her eyes fixed on the muddy high heels, the moss on the corner and the water marks on the ground, capturing the subtle traces that everyone ignored. Lu Chenye, who was in charge of the case, looked at this familiar yet unfamiliar silent consultant, and his memories flooded back - on that rainy night three years ago, he had rudely interrupted her warning. Now, she had returned in a professional manner, with only calmness and distance in her eyes, without any softness from the past.
