Ji Ziyue glanced at Jiang Xin and asked Wu Weijie with hesitation: "Teacher Wu, who is she?" ”

"Jiang Xin, the famous cold beauty in our firm." Wu Weijie snorted lightly and said.

Ji Ziyue asked in a low voice, "Is she dissatisfied with me?" ”

Wu Weijie glanced at Ji Ziyue with some surprise, he was surprised that this newcomer was very wooden, but now it seems that he also has his own careful thoughts.

Wu Weijie said: "She is this kind of person, it would be good if you got used to it after a while." ”

Ji Ziyue said politely: "Thank you, Mr. Wu." ”

Shen Zezhi called Shen Yuzhi to report the matter on Rongcheng's side, especially the notebook.

"You suspect that the plan leak is the notebook. And the person who killed Zhang Zhiheng and stole the notebook was the person in the research institute. On the other end of the phone, Shen Yuzhi asked.

Shen Zezhi said: "Yes, He Lang and I checked carefully, and found that there seemed to be only this one thing in Zhang Zhiheng's study. Zhang Zhiheng has been engaged in research for so many years, and he has participated in a lot of confidential projects, and he knows the rules that documents directly related to this plan will not be taken home. This is why Zhang Zhiheng's death scene seems so hasty. ”

Shen Yuzhi was silent for a while and said, "You just check down according to your own ideas, and find He Lang where you need help." His tone paused, and finally said, "Stay safe." ”

Shen Zezhi smiled slightly: "I know, brother." ”

Last night, He Lang and he searched Zhang Zhiheng's house, and there were no other clues other than that discovery. Shen Zezhi took out a piece of paper from inside his clothes, with a contact information on it.

This contact information belongs to Zhang Zhiheng's wife, Xu Mei, who is a professor at the university and often goes abroad for academic exchanges. She happened to go abroad on the day of Zhang Zhiheng's accident, but as soon as she got off the plane, she received a notice from the police that her husband had an accident. So Xu Mei bought a ticket directly at the airport and rushed back. Now Xu Mei lives in Rongcheng's daughter's house.

Shen Zezhi thought about it and dialed the phone, but the other party kept the voice on standby, just when Shen Zezhi thought that the other party would not borrow the phone, the phone was connected.

"Hello, you're Professor Xu." Shen Zezhi asked.

A tired voice came from there: "I am, who are you?" ”

Shen Zezhi said: "Regarding Director Zhang's case, I want to know a little bit about the situation with you. ”

It took a while for them to reply, "You're a cop?" Haven't you asked it before? What else to ask? ”

Shen Zezhi insisted: "I want to meet you." ”

There was silence for a while and said, "Okay, come here." After saying that, he hung up the phone. Obviously, Xu Mei thought that the police who investigated the case when Shen Ze was investigating didn't even say the address. But this is not a problem, He Lang already knows where Xu Mei lives.

Shen Zezhi left the hotel and got into a black SUV at the door, which was the car He Lang lent him to facilitate his investigation.

Because of Zhang Zhiheng's death, Xu Mei's spirit is very bad, and now his daughter has made an appointment with a psychiatrist for her. Shen Zezhi rang the doorbell, and the person who came to open the door was a young woman, this person was Zhang Zhiheng's daughter Zhang Yao. She's married. Probably because of Xu Mei, she hasn't been at work recently and has been staying at home with her mother.

Zhang Yao saw that Shen Zezhi's face was very bad, and every time the police came, they were reminding Xu Mei of the death of her husband, which was a very bad thing for Xu Mei's body.

"You're a cop? What about the documents? How come I haven't seen you before? Zhang Yao asked vigilantly.

Shen Zezhi took out the document from his clothes and handed it to her, Zhang Yao took the certificate and glanced at it, and his face immediately changed: "Guoan? Are you a member of the national security? ”

Shen Zezhi said: "Yes, our national security is also investigating the death of Director Zhang, and this time I came to learn from Professor Xu about Director Zhang." ”

Zhang Yao glanced back and said, "Okay, you come in." ”

Zhang Yao took Shen Zezhi to Xu Mei's room, and then retreated. Xu Mei sat next to the small table by the window and looked out the window, he was a little younger than Zhang Zhiheng, he was not yet sixty years old this year, but now he had silver hair and looked very haggard.

"Hello Professor Xu Mei, I am from Guoan, and I am responsible for investigating the case of Director Zhang." She said and gave her documents to Xu Mei.

Xu Mei took it and looked at it for a while before asking, "Guoan?" What does Lao Zhang's death have to do with national security? ”

Shen Zezhi sat opposite Xu Mei to get his documents back, and he asked, "Director Zhang is the core personnel of the Rongcheng Pharmaceutical Research Institute, and he himself has participated in many national confidentiality programs. ”

Xu Mei nodded, Zhang Zhiheng's work is somewhat confidential.

Shen Zezhi asked, "Has Director Zhang talked to you about his work at home recently?" ”

Xu Mei shook her head: "No, they have signed a confidentiality policy, and he never talks about work at home." And I don't have anything to do with him in terms of work, and the things I study are not in the same field, and I don't understand what he mentions. ”

"Is there anything wrong with him lately? For example, the emotional aspect. ”

Xu Mei thought for a while, hesitated for a moment and said: "About half a year ago, he was in a very bad mood during that time, as if he had quarreled with someone, and he was angry every day, and once I heard him quarrel with someone on the phone in the study. However, after about a month, his mood returned to normal. ”

Half a year ago? Shen Zezhi thought of what Shen Yuzhi had revealed to him about the mysterious plan before, a study designed in that plan was successful half a year ago, but it seemed to be a problem on the side of the research institute, and the medicine had not been sent over for a long time, and Shen Yuzhi didn't know why. Is the reason for this incident Zhang Zhiheng?

"Professor Xu, do you know what the relationship between Director Zhang and the people in the institute is?" Shen Zezhi asked.

Xu Mei thought for a while: "It should be good, he sometimes has disputes with colleagues in their unit over work matters, but it usually gets better in a few days." It is inevitable that there will be times when there are disagreements when conducting research. There are good ones, but there are no ones who don't deal with them at all. ”

"Have any colleagues from Director Zhang's office ever come to your house?"

Xu Mei said: "I've been here, and several of them have come." Jiang Xin often comes, his father and our family Lao Zhang are college classmates, Jiang Xin came here to work at the invitation of Lao Zhang. There is also a young man named Zheng Mingyuan who has also come to the house, but only once. ”

Zheng Mingyuan?

Shen Zezhi asked: "When did Zheng Mingyuan come, and why did he come?" ”

Xu Mei thought for a while and said, "About a month ago, he came to send a document to Lao Zhang." Lao Zhang never took this kind of thing from home. The document he took that day didn't seem to be very important, so I saw that Lao Zhang was angry but didn't get angry, and after he came, Lao Zhang called him to the study to lecture a few words, and then left the Wu Institute with him. ”

Shen Zezhi thought for a while, and then asked, "Who has the key to your house?" ”

Xu Mei said: "Lao Zhang and I each have a handful, and Yaoyao has a handful." ”

Shen Zezhi nodded, and then Xu Mei asked again: "I looked at your documents just now, your surname is Shen, right?" Xiao Shen, what's going on with Lao Zhang's case? She began to cry as she spoke: "That day he was going to take me to the airport, and I said you should not send me to work, but he had to send it, and said that he would go to work after sending it off." Who knows he didn't go to work and come home. ”

Shen Zezhi frowned: "You said that Director Zhang was going to work that day, but I remember that it was a weekend." ”

Xu Mei nodded: "It's the weekend, just an hour before I left, Lao Zhang received a call, it seems that something happened in the institute and asked him to go." I told him not to send me and go straight to the office. But Lao Zhang said that it was not urgent. ”

Shen Zezhi asked a few more questions, and then said goodbye and left.

Shen Zezhi drove to find He Lang, and he thought about the clues he had just gotten while driving. According to Xu Mei, if nothing else, Zhang Zhiheng will go to the research institute after sending Xu Mei away that day, so she will not be with the murderer at all

Meet. Then, this call is likely to have been made by the murderer or the murderer's accomplices, with the purpose of distracting Zhang Zhiheng. But what they didn't expect was that Zhang Zhiheng returned home for unknown reasons.

Why did he go home? Whoever made that crucial phone call.

The car drove outside a Western restaurant, Shen Zezhi parked the car outside and walked into the western restaurant.

He Lang was sitting on the second floor. Shen Zezhi walked over and sat down and said with a smile: "Why do you make an appointment in the restaurant every time." ”

He Lang crossed his legs and said, "Because I am the boss here, the best thing I do is the catering industry." ”

Shen Zezhi picked up the cup and took a sip of water, and then told He Lang about the clues he had just gotten from Xu Mei.

He Lang frowned and said, "So you mean that if you can find the person who called Zhang Zhiheng that day, maybe you can find the person who killed him." ”

Shen Zezhi nodded.

He Lang asked again: "Jiang Xin and Zheng Tianming, do you think they have something to do with Zhang Zhiheng's death?" ”

Shen Zezhi: "Jiang Xin, I don't think it's possible, her father and Zhang Zhiheng are classmates, she herself is taken care of by Zhang Zhiheng, plus she often goes to Zhang Zhiheng's house, so she should be very familiar with some of Zhang Zhiheng's habits, such as Zhang Zhiheng never talks about work at home, and he doesn't take work-related documents home." What's more, Jiang Xin was also directly involved in that plan, and she almost didn't have to steal anything. ”

The index finger of Shen Zezhi's right hand unconsciously knocked on the table: "As for Zheng Tianming, I know very little about him, but the incident when he went to Zhang Zhiheng's house to deliver documents is indeed quite suspicious." ”

"But he is also a direct participant in this plan. There was no need for him to go to Zhang Zhiheng's house to steal things, he himself knew the plan. ”

Shen Zezhi nodded, he leaned back and said, "If only we could know the specific content of that plan, at least we can help us eliminate the suspect." ”

He Lang said: "Shen has already applied, but it is estimated that it will not be successful." These things are state secrets, and their severity may endanger national security. ”

Shen Zezhi nodded: "I understand." ”
