Testimony in the Fog

Shen Yan, the former head of the criminal investigation team, returned to the police force as a consultant because of the "Nightingale Serial Murder Case" that had not been solved for three years. On a rainy night, a strange murder reappeared in Jiangcheng: the deceased was in a kneeling posture, and black nightingale feathers were left on his chest, which was exactly the same as the traces of the old case. Su Qinghe, an independent evidence appraiser, was invited. With her precise analysis of trace evidence, she injected key clues into the impasse. Her delicate and keen sense was able to understand Shen Yan's silence and perseverance.
