The life committee member is named Zhao Han, and she is usually an introverted girl. Zhao Han's appearance is not outstanding, but he works very carefully. Therefore, everyone unanimously elected her as a life committee. Every time there is a class activity, Zhao Han is responsible for collecting the arrears. This time there was such a mistake, and Zhao Han, who was already introverted, sat in the corner and didn't say a word.

"Zhao Han, what the hell is going on? You'd like to make it clear to everyone. A boy sat on a chair, facing Zhao Han, and urged. However, it can be heard from the tone, and there is not much aggression.

Zhao Han came back to his senses, glanced at the classmates in the class, then got up from his seat and walked to Han Lin's side. Zhao Han stood on the podium and was silent for a while, then bowed to all the students in the class.

"I'm sorry, I betrayed everyone's trust, I lost this thousand dollars." Zhao Han said with guilt on his face.

At this time, the originally noisy chatter in the class disappeared in an instant. Facing Zhao Han's bow and apology, everyone was stunned for a while.

Han Lin glanced at everyone present, then at Zhao Han who was standing beside him, and then gently patted Zhao Han's shoulder to show comfort. "Ladies and gentlemen, if there is a thousand dollars less, it will be a few dozen dollars for each of us. Zhao Han has also done a lot of things for everyone, this time we will each bear this loss, don't let Zhao Han be embarrassed, right? Han Lin wanted to make a big deal small and end this matter.

As soon as Han Lin finished saying his suggestion, the pot exploded under the podium again, and they started to talk about it. "Squad leader, I don't agree with this proposal." Suddenly, I don't know who shouted such a sentence from the seat.

"It's not a matter of much either. It's okay for each of us to have a few dozen extra dollars. However, we have to figure things out. Why did the thousand dollars disappear? If someone stole it, we're going to have to find out about it, right? What if this thief is among us? We can fill the hole this time, but if the thief tastes the sweetness, what about next time? What about next time? We can't keep doing this, can we? ”

"I think so too. You have to figure out what is going on. If it's not clear, I don't want to pay more than a few dozen dollars, why? Xiao Ye also responded.

Han Lin sighed helplessly when he saw everyone's reaction. Almost all classmates asked for a clear statement.

"Zhao Han, just tell everyone what happened." Han Lin glanced apologetically at Zhao Han beside him.

Zhao Han and Han Lin glanced at each other, then at the classmates present, and nodded silently. "As you know, I have kept all the funds for the activities in my custody, and there has never been a problem before. So this time I'm a little bit of a complacent. After lunch, I came to the classroom to study on my own. I was a little thirsty halfway through self-study, so I wanted to go downstairs and buy a cup of milk tea. I thought that the milk tea was downstairs, and I shouldn't have any problems leaving for a while. So I left my bag in the classroom. When I got back to the classroom, I checked the money in my bag, and I didn't notice that I was missing a thousand dollars. It wasn't until the squad leader told me that I was going to pay the money that I counted the amount again. That's when I realized that I was missing a thousand dollars. I'm really sorry everyone. After speaking, Zhao Han bowed to everyone again.

After listening to Zhao Han's words, one of the handsome male classmates asked: "Zhao Han, first of all, are you sure that the amount of money before you go to buy milk tea is still accurate?" "This male classmate's name is Ling Zixuan. Since the beginning of school, there has been a saying in the class, women have Qi Huan, and men have Ling Zixuan. Ling Zixuan is not only handsome, but also outstanding in his learning and work ability.

Zhao Han glanced at Ling Zixuan and nodded. "Yes, all the money was collected in the morning. After collecting it, I counted the amount and there were no mistakes. Until I went to buy milk tea, I carried the money with me, so there shouldn't be a problem. ”

"If that's the case, it means that the time of the theft happened during the time when Zhao Han went to buy milk tea." Ling Zixuan replied.

Zhao Han looked at Ling Zixuan and nodded.

"Zhao Han, how long did it take you to buy milk tea?" Han Lin looked at Ling Zixuan, then turned his head to look at Zhao Han and asked.

"As you know, the milk tea we have downstairs is made in advance. So it took less than ten minutes. Zhao Han glanced at the milk tea that was still on the table and shook his head regretfully.

"So, that's what the thief stole the money during this time." Han Lin frowned as he spoke. "It's not easy. There are people coming and going outside this classroom, and even if you have to adjust the monitoring, the scope is very large. ”

"From the situation that Zhao Han just described, in fact, the scope of our investigation is not so large." Ling Zixuan smiled and spoke. At this time, everyone's eyes were all on Ling Zixuan.

"The reason why I say this is very simple, Zhao Han said that it only took a few minutes before and after she went to buy milk tea. We can calculate it from probability. In these few minutes, what conditions does a thief need if the theft is successful? Ling Zixuan paused, glanced at Zhao Han, and then at the classmates around him.

"How long can it take to steal money, just open the bag and take it." Han Lin stood on the podium and glanced at Ling Zixuan, and replied, his tone a little impatient.

Han Lin has always been not very interested in Ling Zixuan, and the main reason is the class president election at the beginning of the semester. Everyone thinks that Ling Zixuan is the best candidate for squad leader, and unexpectedly, Ling Zixuan did get the overwhelming majority of votes. But in the end, Ling Zixuan actually gave up the position of squad leader by himself. In the end, the position of squad leader was succeeded by Han Lin, who received the second most votes. Everyone will be jealous of someone who is better than themselves, especially the other person as their competitor. Therefore, since the election, Han Lin has regarded Ling Zixuan as his fierce rival in his heart. As for Ling Zixuan, he didn't care much about these things.

"The squad leader is right. But why did the thief know that Zhao Han's bag was in this classroom? Why do you still know that Zhao Han's bag happens to have our activity funds in it today? Why was it so coincidental that he took advantage of the minutes when Zhao Han went out to buy milk tea to complete the theft? Could it be that the thief is the roundworm in Zhao Han's heart? It's unlikely, right? Ling Zixuan asked several questions in a row, and after asking, he looked at the classmates around him and smiled.

"I see, I know." Xiao Qing stared at Ling Zixuan with a shy face, and shouted twice excitedly while raising his hand. Everyone set their eyes on Xiaoqing's body in unison. Xiaoqing calmed down his mood, cleared his throat and said, "The thief can know so much, there is only one truth, and that is the thief among us!" ”
