The Perfect Suspect Episode 10 Recap: A Diary's Secret and a Premeditated Murder
The web of deceit connecting the deaths of Luo Lijuan, Qian Cheng, and Yang Yan grows tighter, pulling the main players toward an inevitable reckoning. In an episode packed with revelations, a torn diary page points to psychological torture, a seemingly benevolent CEO is arrested in public, and a quiet sketching trip at a reservoir is exposed as the chilling rehearsal for a perfect murder.
The Race for the U-Drive
Following a lead from a design on his daughter's handbag, Zhong Ning races to an amusement park locker, hoping to find a crucial U-drive left behind by the deceased Qian Cheng. He's too late. Liu Renkai's subordinate, Ah Long, has already retrieved the evidence. After copying its contents, Liu orders Ah Long to take his son and disappear into the countryside to stay clear of the dangerous Zhao Qian. Though Zhong Ning finds the locker empty, he manages to identify the man from security footage as Li Xiang, and the police move in quickly to make an arrest.
An Arrest at the Charity Gala
Despite the tightening police net, Liu Renkai attempts a bold move to launder his reputation, appearing at a high-profile Green Cloud Group charity event. He projects the image of a doting family man, though his daughter, Liu Zixuan, coldly shrugs off her mother's touch and avoids Zhong Ning. The facade shatters when the special task force storms the event. Their key witness, Li Xiang, has confessed. As he's being led away, Liu Renkai makes a final, desperate claim: he was with Zhao Qian on the night Xiao Dade was murdered, providing her with an alibi while implicating her in the process.
The arrest comes just after Liu uses a recording from Qian Cheng to blackmail Zhao Qian. Later, when Zhao Qian confronts him about his apparent carelessness, he scoffs, revealing his leverage: "I have his parents."
A Diary's Deadly Clue
The investigation into Luo Lijuan's suicide takes a sharp turn when an anonymous boy delivers her diary to the law firm. Crucially, the entry for March 20th, the day she died, has been ripped out. The remaining impressions on the next page hint at a dark secret, putting Zhao Qian squarely in the frame.
The truth is finally pieced together through a private investigator's business card found among Yang Youmo's belongings. A year prior, Fang Qinchun had hired the P.I. to investigate Qian Cheng. The investigator inadvertently captured photos of Zhao Qian dropping Yang Youmo home. Luo Lijuan witnessed this meeting and was later confronted by Zhao Qian, who venomously told her, "You're better off dead than living so humbly." This confirms that the mysterious "female ghost under the sun" mentioned in Luo Lijuan's diary was none other than Zhao Qian, who had been systematically tormenting her.
Sketching a Murder
Meanwhile, Zhong Ning revisits the reservoir where Yang Yan, Yang Youmo's wife, drowned. A local villager provides a damning piece of information: a month before Yang Yan's death, her husband Yang Youmo had visited the reservoir alone. He spent time sketching the area and, more importantly, made detailed inquiries about the reservoir's flood discharge schedule over the years. This revelation reframes Yang Yan's drowning from a tragic accident into a meticulously planned murder.
As this thread unravels, another potential crisis is brewing. Liu Renkai's daughter, Liu Zixuan, who has become obsessed with a picture book illustrated by the deceased Yang Yan, recognizes a location from the drawings. Following the map in the book, she cycles off alone toward a derelict factory, heading straight into unknown danger.
Spoilers: What's Next?
Liu Zixuan's solo expedition to the abandoned factory will place her in grave peril. The contents of the torn diary page are set to be revealed, exposing Zhao Qian's darkest secrets. Furthermore, the reservoir's flood discharge timetable will become the irrefutable evidence that proves Yang Youmo murdered his wife.
