Episode 3 recap: The investigation leads point to Tang Xun.

Gu Ji Ming arranged a meeting to discuss finding a ghostwriter, and he strongly emphasized that this matter must be kept confidential. After the meeting, Mr. Chen called Su Zhen Zhen, as it was actually she who had arranged for someone to help Gu Ji Ming find a ghostwriter, but she didn't let Gu Ji Ming know the truth in order to protect his self-esteem.

Now there are many bestsellers, and if Gu Ji Ming doesn't come out with his next book soon, it will be difficult to maintain the hype, which is also the reason why Su Zhen Zhen did this. Gu Ji Ming cooked a few dishes, and he strongly recommended the carefully prepared braised pork, but Su Zhen Zhen only took a small bite of the lean meat part, and although she praised it as delicious, her chopsticks had already moved to the other dishes.

Su Zhen Zhen wants to open a pottery shop, and the agent has found a suitable shop, so they called her. Gu Ji Ming wanted to accompany her to take a look, but Su Zhen Zhen asked him to go check it out first. As soon as he arrived, Gu Ji Ming immediately turned around and said it was not suitable, and told the agent not to introduce any more properties in that area.

Jiang Guang Ming came home from work and brought a fish. His mother said that Xiao Xu had come by today and brought some things, but she didn't keep them. The mother has always felt that Xiao Xu is a good person, and her infidelity was perhaps just a momentary lapse of judgment, and she hopes her daughter will reconsider their relationship. At this time, the mother's dance partner, Uncle Wang, came in uninvited, so Jiang Guang Ming didn't have dinner at home.

After the holiday, Shi Luo's first day back at work, Jiang Guang Ming was waiting for him on the rooftop. Shi Luo honestly reported the investigation results from Fanghai City, and Jiang Guang Ming was not angry, as there can be multiple directions in solving a case, and it's possible to go down the wrong path at times.

The two of them went to the area around Zhang Qing's home again, and Shi Luo learned from an elderly man that a man in his 50s had frequently been feeding dogs in the area a few days before the incident a year ago, but he hasn't been seen since then. Shi Luo quickly called Jiang Guang Ming over and asked the elderly man detailed questions about the man's appearance and height, and based on the description, Jiang Guang Ming had Shi Luo go investigate the nearby hotels.

Liu Qiang and Xiao Zhang provided technical support, printing photos of the hotel guests, and Shi Luo wasted no time taking the photos to have the elderly man identify.

Upon identification, the uncle recognized the person. Shi Luo continued the in-depth investigation and found that the person's name was Tang Xun, a writer, who had a book signing event scheduled on the day of the incident but canceled it due to health issues. On the 19th at dawn, Tang Xun checked out of the hotel.

Shi Luo was unable to reach Jiang Guang Ming, so he went directly to her home to report the investigation results. Shi Luo was unaware of the marital discord between Jiang Guang Ming and her husband, and Jiang Guang Ming couldn't force him to leave, so she had him stay for a meal.

Shi Luo kept addressing Jiang Guang Ming as "brother-in-law," which made her uncomfortable, but she didn't react. After Shi Luo left, Jiang Guang Ming saw an opportunity, and she told her husband to go to the Civil Affairs Bureau the next afternoon, implying that she wanted to file for divorce.

Upon checking the surveillance footage from the Rui Li Hotel, they found that Tang Xun's behavior on the night of the incident was suspicious, and Zhang Qing's dog was also spotted outside the hotel. They then learned that Tang Xun had passed away due to illness and that he had a wife living in Jinzhou. Jiang Guang Ming quickly returned to the bureau and reported to Director Wang, and then headed to Jinzhou that afternoon.

Before going to Jinzhou, Jiang Guang Ming went to the Civil Affairs Bureau, but her husband made an excuse about having a meeting, and they decided to handle it another day. Shi Luo noticed the change in atmosphere during the dinner the previous night, and he realized something was off since Jiang Guang Ming went to the Civil Affairs Bureau. Upon arriving at No. 16 Shallow Bay in Jinzhou, they interviewed Tang Xun's wife and Jiang Guang Ming took a postcard that was sent from Fang Hai but without a return address.

As they were leaving, Tang Xun's wife watched them from the window, and when Jiang Guang Ming looked in her direction, she quickly hid behind the curtain. After Jiang Guang Ming and Shi Luo left, Tang Xun's wife slid a file folder into an old wooden box, as if the folder contained a secret that she didn't want to be discovered.
