Female forensic doctor Su Yan and criminal investigation team leader Lu Zheng are childhood best friends who have known each other for 28 years. One performs a scalpel to restore the cause of death, and the other leads a team to hunt down the murderer and find the real culprit. Together, they are on the front line of the small town's public security. This book is narrated in the first person by Su Yan, and contains twelve independent unit cases and a serial case main line, ranging from the murder of his wife by defrauding the insurance company, family feud, poisoning in the workplace, and lynching revenge. The cases do not deliberately exaggerate the bloody violence, but focus on the greed, obsession and darkness in the folds of the human heart.
The full text is logically rigorous, the forensic examination and criminal investigation reasoning are professional and realistic, and the rhythm is relaxed and moderate. The two people's daily rest and mutual support are interspersed between the high-density case detection. They have seen the most unbearable malice, and they also adhere to the firmest professional bottom line. They use evidence to restore the truth of each murder case, seek justice for the deceased, and witness the grayscale of human nature and the weight of perseverance in old cases and new incidents.
Purpose: The work is based on the grassroots criminal investigation and forensic profession, and uses unit cases as a carrier to dissect complex human nature. It not only shows the malice caused by greed and obsession, but also describes the struggle and redemption in difficult situations, and clearly conveys the value orientation of "procedural justice is higher than lynching revenge". At the same time, it depicts the bond between the two heroines spanning more than 20 years, showing the professionalism, tenacity and mutual support of women in the criminal investigation position, and interpreting the professional belief of "serving the rights of the living and speaking for the dead."
