The Cost of One Hesitant Moment
Tipped off by a mysterious caller that a murder was about to take place, two police officers rushed to an old residential building. Splitting up to search the area, rookie cop Leng Xiao Bing stumbled onto the scene just as the crime was unfolding. Face to face with the killer, fear and hesitation paralysed him. Before he could pull the trigger, he was knocked unconscious.
The consequences were devastating. Xia Mu's beloved teacher and guardian, Xia JinLan, was brutally murdered. Hidden in the attic, young Xia Mu witnessed the horrifying aftermath — the policeman entering the apartment, followed by the exit of the psychopathic serial killer. In the chaos, the second officer also lost his life.
Seventeen years later, Xia Mu graduates top of his class from the police academy and joins the very department investigating the unsolved serial murders. Still haunted by the tragedy, he confronts Leng Xiao Bing, demanding to know why he failed to act that night and save the woman Xia Mu regarded as a mother. The trauma of the past, combined with a more recent event, has pushed Xia Mu dangerously close to the edge.
Enter Shen Yu, an intelligent and enigmatic psychologist assisting with a case. She is the daughter of Shen Haiyang, a doctor who mysteriously disappeared around the time of Xia JinLan's murder. Shen Yu's suspicious behaviour leads Xia Mu to believe she is protecting her father, who is now a suspect and may still be in hiding. Determined to clear his name, Shen Yu takes increasingly reckless risks, gradually entangling herself in deception and making herself appear complicit.
After seventeen years of silence, a new murder emerges bearing chilling similarities to the old cases. Even more disturbing, a set of skeletons estimated to be 15–20 years old is discovered, opening an entirely new line of investigation. The revelation confirms one terrifying truth — the serial killer has never stopped lurking in the shadows.
Zhao Liying delivers an outstanding performance as Shen Yu. Intelligent, manipulative, and morally ruthless. Shen Yu is not an easy character to like, yet Zhao Liying portrays her with such conviction that I found myself simultaneously fascinated and frustrated by her desperate determination to protect her father. It is another reminder of why she remains one of the strongest actresses in Chinese drama today.
I came across comments complaining that the drama lacked romance. Interestingly, I heard similar criticism directed at Whispers of Fate. That made me wonder why some viewers consider romance essential in every story. Romance can certainly add flavour, but it is not a requirement for a compelling drama. Who Is the Murderer thrives on psychological tension, guilt, trauma, and moral ambiguity rather than romantic distraction.
Modern Chinese thrillers are not usually my preferred genre. Many tend to feel overly cautious, restrained, and somewhat sterile, often sacrificing realism in the process. This drama still carries some of those traits, but its layered mystery and intriguing twists kept me thoroughly engaged. The story constantly shifts your suspicions, and just when you think you have pieced everything together, it quietly unsettles you again.
It may not be perfect, but I found it gripping, emotionally heavy, and surprisingly addictive. A highly recommended watch for viewers who enjoy dark psychological mysteries rather than romance-driven storytelling.
