Zhou Bin received the secondment notice from the bureau three days after he was injured, and he was entangled with Zhang Liuwu, who was lame every day to bring food, fruits and flowers to himself.

He noticed that the girl seemed to have a bad brain, and told her not to always run to the team, which would not affect him well, and it didn't matter if he was injured.

Zhang Liuwu didn't seem to understand, but still went his own way.

When Zhou Bin saw the secondment notice, he still had a little regret, but the secondment was not a callback, which meant that he would have to return to the traffic police force after a while.

However, seeing Zhang Liuwu who was not leaving, Zhou Bin felt that the secondment was also good, at least he could get rid of this little girl with a bad brain.

Zhou Bin explained to the deputy captain and hurried back to report to Director Yuan.

The time he spent in the traffic police force really made him live like a year, and he was still thinking about the unfinished case.

Zhang Liuwu drove the car and secretly followed Zhou Bin, but was thrown off by him halfway through.

Zhou Bin, who returned to the Public Security Bureau, looked at the familiar office building in front of him and suddenly felt a sense of intimacy in his heart, not that he didn't love the traffic police, but he had a deeper affection for this place, after all, he worked here as soon as he graduated.

Zhou Bin excitedly walked briskly and went directly to Director Yuan's office.

Just about to knock on the door, he saw that the door was opened, Zheng Si came out of it and saw Zhou Bin stunned for a moment, and then laughed: "Is there something to find Director Yuan?"

Zhou Bin nodded and smiled as an answer, and quickly went inside, without the intention of greeting Zheng Si.

Zheng Si squinted his eyes and slowly closed the door before leaving.

"Director Yuan, Zhou Bin is back to report. Zhou Bin was very happy to greet Director Yuan.

"Oh, Captain Zhou is back, sit down, it's just so that I can arrange your work for coming back this time. Director Yuan put down the folder in his hand and took out a piece of paper from the drawer.

"Team Zhou, that's the case, the nature of the incident of food poisoning in the kindergarten and the murder of the hospital security guards is very bad, the impact is very bad, and the leaders of the city attach great importance to it.

The comrades of the criminal police team are busy with some important and serious cases, and the organization has repeatedly considered seconding you back to take charge of the murder of the kindergarten and hospital security guards. ”

Zhou Bin was a little puzzled when he heard Director Yuan's words and asked, "Director Yuan, is there no mistake, are you?" These two cases involve me and my family, and I need to avoid them according to the process. ”

"Captain Zhou, this rule is that the dead are alive, and we all believe in your professional ethics, so go to work with confidence. Director Yuan gave the paper in his hand to Zhou Bin.

Zhou Bin took it and saw that it was the names and contact information of several colleagues who assisted him in his work, most of whom were interns who had not yet passed the internship period.

"Thank you for the trust and attention of the organization. Although Zhou Bin was not very reluctant, but considering that if he refused, he would definitely have to go to the traffic police team, so the ninja was uncomfortable first, and then came back to discuss with the director after he solved the case to participate in the previous case.

Zhou Bin left the Public Security Bureau and rode an electric car to the kindergarten, and the poisoned children, including Yueyue, had already returned from danger to continue their classes.

My former colleagues also went to the kindergarten to investigate and make detailed records, but they didn't know why the children were poisoned, what the source of the poison was, and where it came from.

The teachers and support staff all said the same thing: I don't know!

I also called up all the surveillance videos, and several colleagues watched back and forth for two days and didn't find anything wrong.

Progress on the case stalled.

Zhou Bin simply looked at the relevant materials and records of the case, and understood that the crux of the problem was in the kindergarten, so he first found the principal to check the personnel files of all the employees.

When he saw the logistics staff, he found something suspicious.

Because of the case, Zhou Bin will often go to the household registration department to inquire about the information of relevant personnel for comparison.

Zhou Bin was deeply impressed by the eyewitness in the case for exactly one year, because that person was an internist at the hospital and had a high prestige in the First Hospital.

The reason why Zhou Bin paid attention to him was because at that time he felt that the time and place where the hospital witnessed the suspect committing the crime were a bit strange.

The doctor is busy, this is the consensus of everyone, so why did he just witness the process of the suspect's murder.

At that time, Zhou Bin checked the information of the doctor's family, and it was only because of his feelings that he felt that he should check it like this to be worthy of his conscience.

It's just that Zhou Bin didn't find out anything, and the suspect confessed to his crime.

Zhou Bin memorized the information of the doctor's entire family, thanks to the efficient memorization method he had practiced when he was studying.

And today, when Zhou Bin looked at the personnel file of the kindergarten, he found the information of the doctor's family back then, this person is the aunt of the logistics kitchen, the sister of the doctor, she married the hospital logistics security guard.

Zhou Bin narrowed his eyes slightly, the kindergarten logistics and the hospital security guards are husband and wife, and the kindergarten children have food poisoning, and the security guards hurt people, this is too obvious, right?

Is this relationship easy to find? Is someone deliberately bribing them or do they have something else to hide?

Zhou Bin put down the case file, the kindergarten happened to be the time of recess at this time, and the children all ran out of the classroom happily to play in the big yard, sliding on the slide and rocking the wooden horse.

Zhou Bin looked out of the window and inadvertently saw his daughter Yueyue, her little face was still a little pale, and the doctor said that although the toxins were almost removed, it still hurt her internal organs and needed more recuperation.

The children who used to be alive have now become a little timid.

Zhou Bin felt distressed in his heart.
