Under the Skin Episode 18 Recap
> Under the Skin Recap
After He Rongyue found car window cleaner, she guessed that the person who cleaned the scene might have driven to the Whig Hotel. Shen Yi took advantage of Du Cheng getting out of the car to buy something and secretly took Du Cheng's car window cleaner. Du Qing invited Shen Yi to her home for dinner. At the dinner table, Shen Yi questioned Du Cheng's recent abnormal state. Du Cheng only said he was too tired.
Shen Yi wanted to press him further but was interrupted by Du Qing. Shen Yi asked about Du Cheng's watch. Du Cheng said the watch was broken. Shen Yi said he knew a watch repairer. Du Qing then took out the repaired watch for Shen Yi to see. Shen Yi found that the scratch on the watch glass was gone. Lu Haizhou found Li Han, Lao Yan (Yan Tansheng), and Jiang Feng to ask about Du Cheng's personality traits.
When chatting about the homicide caused by the human trafficking case, Lu Haizhou pointedly said that the killer is always one step ahead of the police. Lu Haizhou visited Shen Yi's office and tried to learn about Du Cheng from Shen Yi. Shen Yi suggested that Lu Haizhou communicate directly with Du Cheng. Lu Haizhou asked if Shen Yi had any clues. Shen Yi recalled all of Du Cheng's abnormalities but did not tell Lu Haizhou.
Du Cheng went alone to the seaside cottage late at night to investigate. M lived here before she died. M's diary had been torn out. Du Cheng used a pencil to make a rubbing of the imprint left on the last page of the diary. The file M sent to Du Cheng the night of the incident was a photo, and she told Du Cheng that the man in the photo was the killer of Lei Yifei.
Du Cheng left the photo in the house before leaving. Shen Yi found a large amount of salt stains while examining M's belongings. He suspected that M had stayed by the sea before she died. Shen Yi didn't want to alarm anyone and wanted to investigate by the sea alone. After Lu Haizhou learned about this, he wanted to dispatch municipal criminal police. Du Cheng immediately decided to send someone to act with Shen Yi.
During the search, Shen Yi, who was in the same group as Du Cheng, secretly checked Du Cheng's driving record. But the driving record had already been deleted by Du Cheng. Du Cheng discovered Shen Yi's action after returning to the car but did not point it out. Everyone found the seaside cottage based on the clue provided by the grocery store, and the photo left by Du Cheng became the most important clue.
Investigations revealed that the man in the photo was named Zhou Jun. Du Cheng immediately decided to arrest Zhou Jun. In private, Lu Haizhou frankly said that Du Cheng's decision was too hasty. After all, Zhou Jun had an alibi at the time of the incident. Shen Yi did not agree with Lu Haizhou's idea. Zhou Jun, who worked at the library, was brought to the police station.
But after more than ten hours of questioning, Zhou Jun did not provide any valuable clues. Du Cheng personally questioned Zhou Jun whether he killed Lei Yifei. Zhou Jun, looking dazed, remained silent. Seeing that the detention time was about to expire, Du Cheng had an emotional breakdown. Jiang Feng pulled Du Cheng out of the interrogation room. Lu Haizhou questioned how Du Cheng knew Zhou Jun was the killer of Lei Yifei.
Du Cheng stated that he was just bluffing Zhou Jun. Du Cheng personally escorted Zhou Jun back to the library and was led to the restroom by Zhou Jun under surveillance. Li Han found a blurry figure in the surveillance video of the Whig Hotel. Lu Haizhou wanted to ask the technicians from Tongcheng Group to help restore the image clarity. Shen Yi proposed that he would draw a portrait of the figure.
After carefully observing the video screenshots, Shen Yi began to draw the portrait. But each portrait only drew half of the figure. Shen Yi's emotions were extremely unstable while looking at the portraits. Finally, he still drew a complete portrait, and the person in the portrait was surprisingly Du Cheng. Jiang Feng looked for Shen Yi early in the morning for the portrait, but Shen Yi was not in the office.
Jiang Feng was very surprised after seeing Du Cheng's portrait on the drawing board. And at this time, Du Cheng and Shen Yi were together. Shen Yi pressed Du Cheng, and Du Cheng started telling the story from the night of the incident. On the night of the incident, M arranged to meet Du Cheng on the fifth floor of the Whig Hotel. But as soon as Du Cheng got to the second floor, M fell from a height.
Du Cheng saw what the killer looked like. M had told Du Cheng before she died that someone was chasing her, and her purpose for seeking Du Cheng's cooperation was also to seek his protection. Du Cheng realized that there was a powerful mastermind behind the whole thing, so he decided to play along and try to use himself as bait to lure the mastermind out. Du Cheng did not want Shen Yi to be involved, because Shen Yi was his bottom line and the only chance to catch the real killer.
