Director Dai and Tan Weixian were very surprised why Zhou Yun slipped in, but were not discovered by the person on duty. Seeing that the person on duty had to tighten the ropes. The big man came in, but there was no news. If the bad guy came in, it would be a tragedy.

However, they were soon attracted by Zhou Yun's words.

“What’s new?”

Zhou Yun sat down and said that he had checked out from the empty house, climbed over the wall and entered the yard of the epidemic prevention center, and found a disabled telephone line.

When Zhou Yun finished speaking, the two men immediately pulled Zhou Yun out with flashlights.

Zhou Yun brought them to the side of the waste line like thieves. The main reason was that he did not want to alarm the people in the epidemic prevention center.

When Director Dai and Tan Wei first saw the scrap line, they both agreed with Zhou Yun's statement.

Tan Weixian said: "This wall hole should be the office of the Department of Epidemic Prevention. There are three people working in that office."

Back in the small conference room, Tan Wei first introduced the situation of Yike's office.

There are three people working in that office, one section chief and two clerks.

Units like the Epidemic Prevention Institute are units that have not been opened for ten years. Because they are unpopular, they are not valued. The personnel are pressed down again and again. In the police station, there are hundreds of people in one subject, but there are only three in this subject.

One department, also known as the Immunity Prevention Department, has its main function to check whether there are viruses in various dangerous places in Changsha City.

If you get serious about this kind of thing, you will never finish things. But if you don’t be serious, you will be idle all day long.

In this section, one section chief is a male, two clerks, and a female. One is twenty-seven or eighteen years old and is very beautiful. The other is a little girl of seventeen or eighteen years old, who has just started working for only three months.

After exclusion, Zhou Yun ruled out the 17 or 18-year-old girl.

Tan Weixian said: "The person who spoke to the colonel in the phone recording was a man aged 37 or 38, and should be the section chief."

Director Dai also agreed with this view. In one subject, there is only one telephone, and usually it is placed in the section chief's office.

Suspicion is suspicion, but three people in that subject should be suspicious. In addition to them, other people can also enter the office and call when they are not around.

So, Director Dai decided to ask the three people and try it out.

Half an hour later, the Military Commission personnel brought the section chief in first. Tan Wei first presided over the trial.

"Tell me about your activities on the 12th."

The section chief was a little anxious and told him about his situation from morning to get off work on the 12th. His home lived outside and went home after work.

Tan Weixian asked: "Where are you at an hour around 10 o'clock in the morning?"

The section chief thought for a while and said, "I went to the third floor."

"What are you doing on the third floor?"

"I received a call and said that the director was looking for me, so I went to the director's office."

Zhou Yun glanced at the section chief and asked, "What's the matter with you, the director?"

"I didn't see the director! I waited on the third floor for an hour, but before I could wait for the director's person, I finally went to the canteen for dinner."

Tan Wei first asked: "Is anyone proof?"

The section chief thought for a while and said, "The office of the third department is on the second floor, right next to the stairs. When I went up, I saw Xiao Dong from the third department. When I got down, I met Xiao Wang and went to the canteen with him."

Zhou Yun asked: "Who called you?"

"It's like the director's adjutant, but not very similar."

"Why do you say that?"

"Because the sound is a bit sharp. However, as soon as you hear it, you can know that it is the voice of the director and deputy officer."

The talk was over soon and the director left.

Tan Weixian found Xiao Dong from the third department. Xiao Dong said that his office was facing the stairs. Usually, people who went up the third floor would go up from his eyes. That day, he did see the section chief of the first department going up the third floor.

Later, Xiao Wang also confirmed that at 11:30, he went downstairs with the section chief of the department and went to the canteen for dinner.

After asking, Zhou Yun said: "The situation is a bit wrong! It seems that the chief of the first department was waiting for the director of the third department when the colonel called. He had no time to commit the crime."

Tan Weixian said: "I also investigated another person from the third department. One person also saw the head of the first department going up to the third floor. When the first department went downstairs, he met Xiao Wang, and there was someone in the third department office, and he also proved this."

Director Dai said: "So, the chief of the Section 1 is not a suspect? But his voice..."

Zhou Yun said: "It should be someone who imitated the voice of the chief of the first department and spoke to the colonel on the phone."

Tan Weixian also agreed with this analysis.

There are only three people in one section, and the section chief is not the suspect, only two people are left.

Director Dai said: "Now I want to ask when the director left."

Then, the director was invited in.

According to the director, he went to the municipal government for a meeting that day and left the epidemic prevention center at 8:30. Moreover, he did not ask the adjutant to call the department head up. The adjutant was not in the institute and went to the municipal government with him.

After hearing the director's words, Tan Wei summoned the adjutant again. The adjutant also confirmed the director's words.

Zhou Yun said: "It is obvious that someone knew that the director had left, so he pretended to be an adjutant and called the director. Because the director's office door was closed, the chief of the department did not dare to break in, so he sat on a bench outside and waited for the director to summon him. This wait took more than an hour."

Tan Weixian said: "It should be that there is any warning from the external line. The man knew that there was a call in, so he thought of transferring the director out. After the director left, he connected the external line and spoke to the colonel."

Director Dai said: "There are suspicions among the remaining two people."

Tan Weixian said: "When the director left, there was no one in the office of the department. The little girl went to the office on the second floor to talk to people. The older woman was not in the epidemic prevention center."

Zhou Yun asked: "What did he do when he went out?"

Tan Weixian said: "Before the director received the call, he asked the woman to leave the epidemic prevention center and go to a store next door to buy light bulbs. The light bulbs in their office were broken."

Director Dai asked: "Did anyone confirm that she was out?"

"Yes! There is her entry and exit registration form for the doorman."

Director Dai asked again: "Has that little girl been in the office on the second floor?"

"Always! There are five people who testify."

This made the matter a deadlock.

There are only three people in the department office. Now, the three people are not on the scene and there is no time to commit crimes. Could it be someone from other departments?

Zhou Yun said: "Check the call that director answered immediately. When did it come here?"

After more than ten minutes, I found out that the phone number was called at 10:08. The phone number from the epidemic prevention institute is not like the phone number of later companies, and each department has a telephone line to pull in. It has to pass through the telephone bureau. Therefore, the time can be found.
