readx; He Yun carefully examined the three criminal suspects he had drawn up, but his doubts were very deep, after all, there were huge loopholes in Xu Long and Zhuge Qingyun's alibi certificates, and the "presence" proof of Ink and Ink was also very suspicious. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 infoTherefore, it is very difficult to determine who is the real thief who steals the class fee.

Calm down, calm down, calm down again. As long as he is a criminal, then, no matter how perfect the alibi, he has his flaws. He Yun forced himself to calm down, and his gaze, like a sharp knife, slashed across the faces of Xu Long, Zhuge Qingyun, and Shui Mo Nong. Xu Long's face was very gloomy, as if he had something in his heart that made him resentful; Zhuge Qingyun still has that big grinning image, it seems that He Yun doubts him, and he doesn't mind at all; Ink Thick and Pretty had a pale face, apparently just recovering from the "heat stroke" incident.

He Yun sneered a few times in his heart and asked, "What did you do after you left the playground in the last class?" ”

During the outdoor class, the only people who left were Xu Long, Zhuge Qingyun, Shui Mo Nong, Xin Ke and a few other girls, and He Yun's words were obviously aimed at them (her). Shui Mo was not convinced, and asked loudly: "Heyun, are you suspicious of us?" If you suspect us, forget it, even Ke'er has to doubt it, she is your girlfriend, what kind of girl she is, I'm afraid you know better than us. Even she doubts, you, you, do you still have a conscience? ”

He Yun replied with a smile: "Mo Nong, please remember that as a detective, the first thing you have to do is not to show favoritism. Don't say it's my girlfriend, it's my parents, who have committed a crime, and as long as I still have a breath of air, I won't let them go unpunished! ”

What I said, everyone was full of admiration. Zhuge Qingyun cleared his throat: "I've been in the toilet, but I don't know what's going on today, there is no one in the toilet, so it's unlikely that my alibi will be established Brother Yun, am I the most suspicious of committing a crime?" “

"Not necessarily," He Yun shook his head, "Your alibi may also be valid, provided that you find witnesses who can prove that you haven't been out of the toilet since you entered the toilet." “

Zhuge Qingyun's face collapsed suddenly: "Brother Yun, aren't you asking for my life?" With such a big school, where can I find some bullshit witnesses? If I say that from you, I really can't wash it by jumping into the Yellow River."

Everyone laughed, Xu Long glanced at Zhuge Qingyun, and then looked at He Yun: "After I left the playground, I went to the infirmary to deal with the sprain of my wrist, and the school doctor in the infirmary should be able to prove it, but I'm not sure, after all, there are too many people who go to the infirmary every day, and it is possible that the school doctor can't remember it." “

"I, I carried my sisters back to the classroom, and it wasn't until Kerr came back, pinched me, and fed me a few sips of cold water that I came to my senses. How about it, the great detective and classmate Yun, do you have a clue? "Ink is still very harmonious, who makes him even doubt his girlfriend? Although, she still admires the selfless words spoken by He Yun.

He Yun laughed a few times, stood up, and walked out of the classroom. In this case, he could already say for sure who the thief was, but he had no evidence to prove his conjecture. Without evidence, no matter how wonderful the reasoning is, it is just wishful thinking. He turned his head and looked at the three of them earnestly from top to bottom and bottom to top. Suddenly, he saw a very inconspicuous white mark on Xu Long's right wrist. What is that? Is it medicine? Why is it applied underneath the purple potion? Suddenly, Kazumo smiled. I see, his alibi turned out to be so valid.

lit a cigarette, took two puffs with Heyun, paced into the classroom, and threw one to Zhuge Qingyun and Xu Long, and he noticed that Xu Long easily received the cigarette roll with his right hand. He Yun smiled, he was about to speak, but he heard a sentence from behind him, "He Yun, where is the class fee you charged?" I've been waiting for you for an hour and a half, you know? “

"Well, this, teacher, I forgot, there was a lot of things this morning, and I ignored it. But you wait a little longer, twenty minutes at most. I'll put it away and send it to you right away. He Yun smiled awkwardly.

"It's okay, it's not in a hurry anyway, and we don't have a place to use money now. But this time you'll have to remember. “

"Don't worry, guest officer, you're good to go." He Yun sent the head teacher away, turned his head, and said coldly: "It's all this time, aren't you going to admit it?" Xu Long? “

"What do I admit?" Xu Long asked curiously.

"If you don't see the coffin, don't cry, well, I'll tell you, what do you have to admit. It's you, who stole the class fee I put away! “

Everyone was amazed, curious, puzzled, and most of all, puzzled. He Yun took a puff of cigarette and said slowly: "In this case, there are the following doubts. First, there is the question of whether the perpetrator's alibi is established or not, second, the time of the crime, and third, the motive for the crime. So, let me start with the second doubt, which is best explained. After collecting all the pay, I put it in my cupboard, but it was unlocked. After that, it was an outdoor firearms lesson, and I was the last person to leave the classroom. The one who left before me was Xu Long. Then, the time to commit the crime is only in class. Moreover, at this level, there are only two classes, so are the people in that class interested in getting rich? The answer is no, because the surveillance in the corridor will record their every move. However, the surveillance was too far away from the door of our class to see the face of the perpetrator, which also gave the perpetrator an opportunity.

Next, there is the question of whether the alibi is true or not. I wonder if you've ever heard of the probability paradox? The more likely it is, the smaller the likelihood of it happening, on the contrary, the more unlikely it is, the greater the likelihood of it happening," He Yun paused, "Zhuge Qingyun is the most suspicious of committing a crime, but it is also the smallest. Because he went to the toilet, and in this way, he was much less likely to commit a crime. Because, once he enters the toilet, and there are people in the toilet, then, his every move will be watched. Even if there is no one in the toilet, then, when he walks out of the toilet, once he is seen, then, he is exposed. So Zhuge Qingyun, pass.

"After that, it's the ink. It is even more unlikely that she will commit a crime, because the girls who sent her back were randomly named by me, and it is impossible for her to collude with her to steal the class fee. Then, that's all left, Xu Long. ”

"But, but Xu Long went to the infirmary to deal with a sprained wrist." Xin Ke asked.

"What if, Xu Long's hand, is not sprained?" He Yun smiled and turned to Xu Long, "I remember, you sprained it, it should be your right hand, right?" So, has your right hand been restored? I remember that you just took my cigarette with your right hand. ”

"But what about the purple potion on Aaron's wrist? This kind of thing, it doesn't seem to be fake, right? Zhuge Qingyun asked puzzled.

"It's not a purple potion, it's something else. Xu Long, let me ask you, what is that circle of white powder on your wrist? ”

Xu Long's face changed drastically, and he hurriedly covered his wrist. "I'll answer for you, it's a circle of starch, and you've deceived us with this kind of thing. You pretended to sprain your wrist and ran to the infirmary, only to return to the school building from the corner of our view. After that, you go into the chemistry room, apply starch and some iodine to your wrists, pretend to be a purple potion, and then go back to the classroom, take the class fee, and leave. Soon after, you return to the classroom, pretend nothing has happened, sit in your seat, and wait for the class to end. You know, as long as there are no accidents, no one will go back to the classroom, so you are not afraid at all. However, you ignore one point, that is, after the water in the starch solution volatilizes, the non-volatile starch remains on your wrist and becomes evidence of your crime! ”

"You're still seeing it, yes, it's me." Xu Long smiled weakly, took out his wallet from his trouser pocket, and returned the money to He Yun.

"But why would you do such a thing?" Zhuge Qingyun asked puzzled.

"I don't want to! But my sister, she, she, she needs money for surgery, but it's still a lot worse, I, I'm ......" Xu Long knelt on the ground, crying weakly. He Yun took out a bank card from his trouser pocket: "The password is 521314, not much money, but I estimate that it is enough for your sister's surgery." I borrowed it from you, remember to pay it back to me. Do you remember what happened? ”

"What? Isn't it just that Aaron borrowed a few stinky money for his sister and you? You don't have to talk about it all the time. Zhuge Qingyun said with a smile. Everyone nodded yes. Xu Long looked at everyone with some surprise: "Brother Yun, everyone, you ...... I'm sorry, I won't be so stupid in the future. ”

He Yun smiled, he picked up the class fee and walked to the head teacher's office. It's a small case, what's the big deal?
