Synopsis: "No, I already know who the murderer is, the murderer is among you, and that person is you—" Wei Hui pointed to one of them. Pen, fun, and www.biquge.info

"Miss Shi, it should be you." Wei Hui put down his fingers and his eyes never left Shi Yutian.

"What are you kidding, how can I Zhang Yue, what's the benefit of me killing him?" Shi Yutian was a little angry when he heard this.

"I'm going to tell you a story, and the content of the story is what I guess......"

Wei Hui slowly walked to the edge of the sofa and sat down, he told a story like someone present, and the content of the story was roughly like this:

There is a little girl, she came to the big city to work and was helpless, she worked harder than others every month just to get more salary every month, she has been supporting the family, and she may have to send a sum of money to the family every month for her parents to live and her sister to go to school. The emperor paid off, she finally did it, she did some performance in a large company and also got the corresponding salary, but just when she felt that her life was gradually on the right track, she learned the news of her mother's illness, she really had no choice so she tried to find a way in the public funds, her actions happened to be seen by Zhang Yue, Zhang Yue may have threatened her, in an emergency she had to kill Zhang Yue......

"The story is all based on my reasoning and speculation, but I don't know if Miss Shi empathizes with my story." Wei Hui lowered his head and played with his nails.

"Do you have any proof?" Shi Yutian's voice lowered, and it was more like a temptation than a question.

Wei Hui waved his hand, only to see Xu Dong holding a laptop in his hand, he showed the display screen to everyone, the display screen showed a video of a surveillance camera, Shi Yutian, Zhang Yang, Cheng Chengcheng and Zhang Yue went to the parking lot in the rain.

"What does this mean?"

"Let's think about it, it was raining so heavily outside, and Shi Yutian was wearing a hoodie at the time, why didn't she wear a hat? I used to think that maybe she forgot that she was wearing a hoodie, but after later investigation, I found out that this was not the case. Wei Hui stood up and walked to the hoodie that had been left in the company yesterday, picked up the clothes, walked to Shi Yutian's side, and lifted the clothes, "Miss Shi, please put on this dress." ”

The rest of the people stood aside and watched this scene, not knowing what kind of medicine was sold in Wei Hui's gourd.

"Then, put on your hat." Wei Hui saw that Shi Yutian was dressed and asked her to put on a coat and hat.

"You're going too far! Why did you order Xiao Tian to do this and that. Standing aside and seeing the current Cheng Chengcheng, he couldn't stand it anymore.

"Because..... I don't dare to wear ........," Shi Yutian sighed, his gaze gradually moving to the floor.

As soon as Shi Yutian's words came out, everyone except Wei Hui was stunned, they didn't understand why she didn't dare to wear it, and the bystanders stood by stupidly, they looked at Wei Hui, they were eager for the truth.

"How can you be sure it's her?" He Jie was a little confused.

"It's very simple, cyanide ions under alkaline conditions, react with ferrous sulfate to form ferrous cyanide salt, and react with iron iron ions after acidification to form Prussian blue, simply put, I borrowed a little chemical from the chemical factory next door and got blue through reflection, which means that there is hydrogen cyanide in her hat, so she doesn't dare to wear a hat, which is ironclad proof."

Then Wei Hui used a voice recorder to record all of Shi Yutian's modus operandi and motives. It turns out that Shi Yutian once majored in chemistry in college, and she is interested in these simple but mysterious bottles and cans, but unfortunately in this society, it is not that you can engage in that aspect of the profession if you like anything, on the contrary, entering the society is like a polishing process, in this process, people's personalities are polished very rounded, of course, there are interests, hobbies and creativity and so on. How sad it is, in the end, Shi Yutian killed people with her own specialty, she loves chemistry, but she finally used her own hands to smear the chemistry in her heart, that simple hobby with indelible stains, which will be permanent, not to be looked at directly.... Maybe there is no threat at all, in fact, Zhang Yue didn't find out about Shi Yutian's embezzlement of public funds at all, but it was this kind of fear that made her commit this terrible crime......

After the incident, Xu Dong sent Wei Hui and He Jie downstairs: "Do you need to get a taxi for you?"

"No need, we can go back, remember to transfer the money to our account~" He Jie walked in front with his hands behind his back, "Brother, let's go first~ See you next time." ”

Xu Dong was about to say something to He Jie again, but He Jie pulled Wei Hui and left directly.

"Xu Dong seems to want to say something to you, it's not good to leave directly."

"It's definitely not important, I don't want to talk nonsense with him~ Go back to the detective agency, I made another amount of money today~" He Jie walked in front like a child.

Two people leisurely wander the lively streets of the city.

"Do you think we should find one or two more people to help out with our detective agency? Now there are only two of us and we are a little too busy. ”

"Hmm....." Wei Hui thought about it, he always thought about the problem from a rational point of view, "I think for the time being, the commission we got is enough for a month or two, but what about later?" If we can't find the case later, do we have to ask someone else to leave? ”

He Jie was a little disappointed when she heard Wei Hui's words, she thought he would agree......

"Let's talk about it then," Wei Hui didn't look at He Jie, making what he thought was the most reasonable answer.

When I was about to arrive at the detective agency, I saw a person squatting at the door of the detective agency, that person looked only in his twenties, with a dignified appearance, white skin, and looked good, his hair was clean, but he was wearing very simple clothes, like a beggar lying on his feet and squatting on the steps of the detective agency.

"What are you doing here, don't sit still, it's in the way of our business." He Jie stepped forward to get rid of that person.

"I'm here to apprentice!" The man stood up and patted the dust off his body.

"I don't have anything to teach you, you go." Wei Hui ignored the man and walked over directly

The man didn't give up, he followed Wei Hui upstairs, "I can do chores for you, you can also take me out to handle the case, I just want to learn from you the knowledge and ideas of solving the case, I am really not a bad person, this is my ID card and household registration book......" He took out a stack of certificates from his bag and prepared to hand them to Wei Hui....
