When I returned to school in the evening, Ziming insisted that I tell me about what happened today, at first they were still shocked by Qiu Bin's analysis of the whole case in the morning, and then they laughed when they heard me say that I was good at drinking coffee during the afternoon interview.

"Let's find a café later, and see how good Zhou Wen is at drinking coffee." Ziming said with a smile.

"Don't make a fuss, I'm annoying. I said to Ziming.

Yang Yang asked me, "What are you bothered about?"

"What do you think Qiu Bin will do if he suspects me and Ma Chaohe of murdering Zhao Yiming?"

Yang Yang's mouth opened wide in surprise when he heard me say this.

Sister Meng Yao didn't speak for a long time, looked at me and said, "Your idea is still quite peculiar, I began to wonder if you killed someone." ”

"What are you kidding, how can I possibly kill someone?"

"Then you have persecution paranoia. Ziming said.

"You're thinking too much, if you conspire, you two have to be so angry with Zhao Yiming to do this, and you are not in the unit all day on Wednesday, no one will still be interviewing the day before and killing people the next day." Sister Meng Yao said.

"Yes, and there is no evidence that you conspired with Brother Chao, right?" Yang Yang asked me.

"That's not true, I remember that Qiu Bin seemed to say that there were only Zhao Yiming's fingerprints on the coffee bag, so it is very likely that the murderer wore gloves, but when the workers in our workshop were working, gloves were also considered labor protection supplies. ”

"It is common to say that anyone can poison and kill her! Including rat medicine, although it has rarely been seen on the market in recent years, but in the early years, it was sold on the street, and anyone could buy it. Just because Zhao Yiming said that you and Ma Chao stole her coffee, will the police only suspect the two of you? You also underestimate the police's ability to handle cases, they will definitely consider it comprehensively. Ziming comforted me and said.

"Ziming is right, you have to believe that the police will not wronged you, don't think about it anymore. "Yang Yang was so anxious that he was like something, for fear that I would drill the horns.

Seeing that Yang Yang was so anxious that he was about to cry, I hurriedly said, "Okay, okay, I don't want to, let's eat, you have to help me look at my resume again." ”

It was my turn to be on duty on Saturday, and when I was about to walk to the workshop, I found that several sewage manhole covers around the large warehouse had all been opened, and there was still residual feces nearby, and I would smell a foul smell when I got closer.

Today's day shift is the D class, I just entered the workshop, a few masters in the class surrounded me, asked me what happened on Thursday, they said that they had asked some gossip from the mouth of the second class just after the night shift, but the specific details are still not clear, and they want me to tell them again.

At this time, the leader of the Ding squad came over and said, "Don't join in the fun, do your own work." Then they all dispersed.

"Let's go, let's go upstairs. "The leader of Class D put his arm around my shoulders and went up to the technical group with me.

"You also made a note yesterday, right? What did the police ask?" I asked while looking for an ashtray in the technical group, taking the cigarette from the squad leader.

"What else can I ask? I don't work night shifts on Wednesday, and the police ask me what time I went upstairs and where I went when I came up. ”

"What do you say?"

"I'm sure I'll be honest, there's surveillance downstairs, and this thing can't be faked. I came up before the squad leader meeting, and went directly to Liu Jianhua's house to smoke, and then I went to the meeting together, and after the meeting, I went downstairs with them. ”

The actual situation is indeed as he said, generally the people in the downstairs team rarely go up to the second floor, and most of them are the squad leaders who come to the meeting or find a clerk to do some personal affairs. The reason why the technical team does not lock the door at night is because the key cabinet of this house contains the keys to all the rooms downstairs, and it is convenient to open the door if there is a surprise inspection by the superior, but generally no one will enter the house.

I told the squad leader Ding again about the situation when Zhao Yiming died on Thursday and Qiu Bin's inference the next day, and after listening to it, he said: "We worked the night shift on Wednesday night, and as far as I know, no one has ever gone up to the second floor, so it is said that there are people in your house during the day on Wednesday and Thursday, and the murderer should be found if he comes in to transfer the bag, so the most likely thing is the person on duty on Wednesday night and your own people, right?" After he finished speaking, he looked at Zhao Yiming's seat, at this time there were only computers and printers left, Zhao Yiming's personal belongings had all disappeared, and it was estimated that someone should have come to her house to clean up yesterday.

On Wednesday night, another deputy director was on duty, he stayed for half a day on Thursday and went back on a break, I am afraid that the police also went to him on Friday to make a record, but I don't think he had a motive to murder Zhao Yiming, although I heard the clerk say before, when the deputy director was just transferred, he was slightly dissatisfied with Zhao Yiming's behavior of often arriving late and leaving early, and once reported to the director, but when he got the director's reply and said, "You don't care", not only did he no longer hold on to this kind of thing, but also took the initiative to work for Zhao Yiming for a few shifts. As for the people in our house, first of all, the girl who took maternity leave was excluded, and among the rest of the people, Li Tianlei and the two new men should not do this kind of thing, after all, they are all in the same camp, but after excluding these people, only Liu Jia and Ma Chao remained, and I don't think they will kill people.

Seeing my depressed expression, the leader of Class Ding went out after smoking, leaving me alone in the technical room to think about the case. The more I thought about it, the more I felt clueless, after all, there were too few clues now, and then I simply stopped thinking about it, and opened the football game that I had secretly installed on the computer and played.

Just when I was getting hooked, the mobile phone in my pocket suddenly rang, and I took out the number I didn't recognize, I thought it was the phone number of a recruiter, because since the last time I submitted my resume at the National Exhibition, I have received a lot of interview calls recently.

"Hey, hello Zhou Wen, I'm Qiu Bin. I heard that you are on duty today, can we meet and talk?"

I don't know why he grabbed me, but after all, the other party was a police officer, so I turned off the game and said to him, "Okay, but I can't leave the unit." ”

"That's okay, I'll go over now, and now I'm at the gate, you're in the technical group, right?"

Qiu Bin soon appeared in front of me, he was still wearing the same clothes he had worn when we went to take notes, his hair looked messy, but his eyes were very bright, and he was holding a half-drunk bottle of mineral water in his hand.

I asked him to sit casually, and he actually sat on the seat before Zhao Yiming, but what he said next shocked me even more: "You see those manhole covers outside, right? We asked someone to open it last night, in order to find out if there were any bags of coffee that Zhao Yiming had lost, because we originally suspected that you and Ma Chao jointly committed this case." ”

I heard him say that, and he didn't speak, but my heart was beating so hard that I guess he could tell I was nervous. "Relax. He smiled and continued: "We didn't find anything other than feces in those manhole covers, so we can basically rule out the suspicion of you and Ma Chao." ”

"What do you mean?" I really didn't understand what he said.

"Yesterday afternoon, Ma Chao came to take notes, and I also asked him what he did on Wednesday. Speaking of this, Qiu Bin glanced at me and asked, "Do you remember what he did on Wednesday?"

"I remember asking him to wipe the machine in the morning until noon, and then in the afternoon Liu Jianhua sent him to check the machine number, right?" I recalled.

"I remember very clearly, he also said so, we later adjusted the monitoring and checked, Ma Chao came earlier than Zhao Yiming in the morning, and then worked downstairs until noon to eat in the canteen, and then because he asked him to check the machine tool number, he didn't even take a lunch break, and went back to the workshop and started working again, until you had a meeting in the evening, after the meeting, according to the people in your house, he didn't come back to the office, and went directly to the man to change his clothes and went to the bathhouse to take a bath. It's a bit inhumane, but it's not something I'm supposed to do, and thanks to the fact that he didn't come into the house for a day, I ruled out the suspicion that he was mixing coffee on Wednesday. ”

I didn't expect Ma Chao to have such a miserable time on Wednesday, he didn't tell me that he had been working all day and had no rest in between.

"Then you think we did it after we came here two Thursdays?" I asked Qiu Bin.

"Listen to me slowly, since neither of you had time to commit the crime on Wednesday, we will definitely suspect that you made a contract for Zhao Yiming's coffee on Thursday morning. But you all came by subway, we retrieved the video records of the station and found that you didn't have coffee when you were in the subway, so the poison can only be obtained by you on the way out of the subway station to the time between entering the unit, but through the time difference between the exit video in the subway and the surveillance video record at the entrance of your factory, the two of you should have come to the factory directly after leaving the subway station, and as you said, it must be possible to come by bicycle, which we can confirm through the bicycle sharing company that the two of you also obtained the riding track of the day。 ”

"So what?" I asked Qiu Bin.

"Therefore, if you still insist on doubting the two of you, then there is only one possibility, that is, you have already thought of a whole set of plans to poison Zhao Yiming, and hid the poisonous bagged coffee on the way to the factory, and then took it out when you went to work on Thursday, took it to the unit, and took all the original coffee of Zhao Yiming and replaced it with your poisonous coffee, but in this way, you need to find the coffee before Zhao Yiming, according to your clerk, the last time Zhao Yiming said that she ran out of coffee and asked her to buy it happened more than a month ago, in order to save trouble, your clerk directly ordered a box of 100 pieces for her online, so it is estimated that there should be at least 70 bags left according to drinking one bag a day. "It's not surprising that I think there may be 90 bags left, because Zhao Yiming rarely comes to work.

Qiu Bin continued: "So the key question is how do you two dispose of so many bags of coffee, the easiest way is to tear open the bags and flush the coffee into the toilet with water, and then burn all the bags." However, the smell produced by the burning of nearly 80 bags must be very pungent, according to the video, after you went up to the second floor, Liu Jianhua also went up after about ten minutes, it is impossible for you to complete this series of actions in such a short period of time and not be noticed by Liu Jianhua, if you have been hiding so many bags of coffee, there are other people around you all day during the day, so it is impossible to destroy them, but when we searched your locker room and other places where you may be hiding things that day, we did not find any traces of coffee bags。 ”

"So you suspect that we threw the coffee into the toilet along with the bag?" I then reacted.

Qiu Bin nodded and said, "That's right, so we came to the factory yesterday and looked for a car to suck up all the dirt in the manhole cover, but we didn't find those bags of coffee." ”

"But even if there are really dozens of coffee bags in those feces, it doesn't prove that this is what Ma Chao and I did, right?"

"No, if there is anything in the feces, it means that the murderer did not have time to take these coffees outside the factory to dispose of them, and it excludes those who went to the second floor on Wednesday, so it is only possible that you and Ma Chao came to work early on Thursday morning. ”

"Then Liu Jianhua can also be, there is another deputy director, weren't they all on the second floor at the time?"

"After Liu Jianhua entered the office, he was talking to others on video, and there was a video, which we have also confirmed. Qiu Bin looked away when he said this, and I guessed that Liu Jianhua should have a tryst with the lover who would have a tryst with him every time he was on duty, maybe at the time of meeting in the evening.

"As for your other deputy director, he went downstairs to eat with the night shift after the shift meeting on Wednesday, and then went home by himself when he saw that there was nothing to do, and did not return to work in the factory until nine o'clock in the morning on Thursday. "I did hear Brother Bo say before that as long as you are brave enough, you can go home when you are on duty and say hello to the class, but you just need to pray not to run into the company's temporary inspection and the group's surprise inspection, especially the group's inspection, if you are found to leave your duty without permission. So for a small minion like me and Ma Chao, at most we walk around the factory when we are on duty, but the leaders are a different matter.

When Qiu Bin said this, he laughed twice and asked me: "Is this unhealthy trend here contagious? I seem to understand why you and Ma Chao are looking for jobs." ”

I didn't answer Qiu Bin's words, and asked him directly: "Since the suspicion of me and Ma Chao has been ruled out, why did you come to me again today?"

"I still want to know about the situation. Qiu Bin saw the ashtray in front of me and took out a pack of cigarettes from his jacket pocket. He pulled out one and asked me, "Do you want one?"

"You're too hard, I'll pump my own. ”

He saw that I lit a running water and said, "You kid is rich enough, I can't afford to smoke that cigarette for so long." After saying that, he pouted the filter of Du Bao in his hand, picked up the rest and lit it up.

I've never seen anyone smoke like this, so I kept staring at him, and he noticed my gaze and said with a smile, "I'm used to it, I smoke so hard, and I just stare at it when I catch up with the spin." ”

Qiu Bin took two puffs of cigarette and continued: "After all, you usually work in the same office as her, so I think it should be more reliable to ask you for news." ”

"But isn't Ma Chao also suspicious? He has been in the factory longer than me, why don't you ask him?"

"Originally, I wanted to go to Ma Chao, but he seems to have some housework to deal with, so I came to you. "I guess Ma Chao definitely didn't want to accept his interrogation, so he used the fact that he had just finished getting married to prevaricate him.

"Does Zhao Yiming usually have any conflicts with your people here?"

"Well......" I muttered, hesitating as I could tell him.

"Don't be burdened, to say that it is your duty to cooperate with our investigation, and privately say that you have to find other jobs anyway, and we will often come to your factory to investigate these days, and others don't know who I heard from the news. ”

"Oh well. I was persuaded by Qiu Bin, "As far as I know, Zhao Yiming was originally an ordinary worker in the scheduled class downstairs before, and for a period of time, due to the lack of people in the technical group on the second floor, and the workshop also needs to be able to work night shifts, so Zhao Yiming was transferred to the technical group on this ground, I don't know how many people signed up at that time, but I am sure that Zhao Yiming is not the most qualified person, so in this process, how many people she has a conflict of interest with I think you can investigate and see." ”

"Just say what you know and know, and I'll do the specific investigation. Why do you think that Zhao Yiming is not the most qualified?"

"At that time, the requirements were for a senior worker and to be able to work night shifts, although Zhao Yiming met both of these requirements, but do you think a person who has just been transferred will directly become the leader of the technical team? And Zhao Yiming seems to have never been on duty for five or six days, the reason is to go home to take her children who have already gone to elementary school. ”

"Okay, I see, you go on. Qiu Bin extinguished the cigarette in the mineral water bottle, then lit a second one, and continued to listen to me.

After she was transferred, she got very close to Li Tianlei and Liu Jianhua, and then by virtue of her privileges, she often arrived late and left early or did not come to work at all, but the attendance sheet was always full attendance, which can be seen by anyone with long eyes, and I feel very dissatisfied. "I relied on myself to completely eliminate suspicion, so I became bold in my speech.

"What privileges does she have?" Qiu Bin asked me.

"This is just my guess, I heard Ma Chao say that her husband is the deputy minister of the company's production department, although she rarely mentions her husband, but at the meeting of Li Tianleisheng, deputy director of the meeting, she said that now these leaders in the workshop are her brothers, I think it is impossible to say this kind of thing with a technical team leader. ”

Seeing that Qiu Bin didn't react, I continued, "Her main job after going upstairs is to record some data recorded in the computer for the daily work measurement records of the class, such as the lathe number, etc., and then someone downstairs should have reported that the technical group raised idlers, and the director let her go downstairs to survey the machine tool when she was fine." In fact, I am responsible for making a list of the monthly census tasks of the machine tool, and then sending them to each class for the workers in the class to conduct their own census. She is not under my control, and from time to time she takes the two new children and a girl who is now on maternity leave, she goes downstairs to wander around, and then plays with the machine tool to check, reports the problems found to the leader, and deducts the wages of the masters so that she can get her own bonus. ”

"Hearing you say this, Zhao Yiming is simply an existence like a public enemy of the whole people. Qiu Bin said after extinguishing the second cigarette.

"Almost, so although I was shocked when I said that she died, but after the shock, I felt that it was not so difficult to understand, and there were a lot of people she offended casually, and I can't say that these people all want her to die, but they must have a grudge against her. "I told Qiu Bin everything I knew, but I didn't want to mention a specific person.

"Okay, I see. Who was sitting across from her? Li Tianlei?" Qiu Bin sat on the chair and turned around and asked me, and after receiving my affirmative answer, he then asked: "Tell me about these people in your office! Except for you and Ma Chao, how is the relationship between other people and her?"

Finally to the point, according to the head of the Ding class, plus Qiu Bin's question just now, I can basically be sure that the police have ruled out the possibility of other people committing crimes, so the murderer is most likely to be from our office.

I thought about it, and then asked Qiu Bin: "The people downstairs have also ruled out suspicion, right?"

Qiu Bin smiled slyly, and then said, "I can't tell you this, just like I said just now, because you are all in the same office, so I came to ask you this." ”

"Okay, Li Tianlei has a very good relationship with her, and the entire technical group can be said to be the world of the two of them, especially this time Li Tianlei has been the deputy director, which has further consolidated the power of the two of them. The other two boys are newcomers, and as far as I know, they are also hugging Zhao Yiming's thighs, and she takes them with her every time she goes to the census or goes out to check them. "The only one left is Liu Jia, although I don't think Liu Jia will poison Zhao Yiming, but now it seems that the situation is the most unfavorable for her.

"There is also Liu Jia, although she didn't hug Zhao Yiming's thigh, she didn't work against Zhao Yiming, and there were no conflicts at work, so there was nothing to say. ”

"You are from the same batch as Liu Jia, right? It seems that you are still in the same school?" Qiu Bin asked me, he must have checked us all out.

"Yes, but I'm telling the truth. ”

"Rest assured, Liu Jia's suspicion has been ruled out. After she came on Wednesday, she went to help your clerk count the wages and assessments of the workshop workers, and she never entered the technical group until she got off work. ”

"Then you didn't say it earlier. "I breathed a sigh of relief, so that all three of us were cleared of suspicion. "You want to talk to me!" I asked, looking at Qiu Bin and throwing him a running water sound.

He took the cigarette, looked at it, and said, "Yes, I'll try a good cigarette too." Then he lit the cigarette and took a big puff, and the smoke that had been walking in his lungs slowly came out of his mouth, "I just want to see if you can tell the truth." Don't say it, this cigarette is expensive, that is, it is better than mine. ”

After that, Qiu Bin chatted with me for a while, and then got up to say goodbye, and before he left, I asked, "Are you going to find Liu Jia next?" Qiu Bin just stood up for a moment, walked out without answering my question.

As soon as Qiu Bin walked out of the workshop, all the people in the Ding class ran up. "That was the policeman, right? Why did he come to you?" he said he didn't say who the murderer was?"

"Don't worry, let Zhou Wen speak slowly. A master stopped their fanatical behavior, and then looked at me with the same expectant eyes.

I was stunned by their curiosity, but it was impossible to tell them the truth, so I made up a nonsense and said, "The police came to confirm whether I had time to commit the crime." ”

"Does he doubt you?" asked one of the children in the class.

The old master knocked him on the head just now and said, "How is it possible, if you really want to suspect Zhou Wen, you should take him to the police station." Right, Zhou Wen?" he didn't forget to look at me, expecting me to affirm his judgment.

"Yes, yes, just to make sure, I told him on Friday, and he just came back today to add some details. ”

"Then he didn't say who the murderer might be?"

"Not really. Besides, if they are really suspicious, they can't tell me. ”

"That's right, it's boring, I thought there was some news! Dispersed!" The group of them found that they couldn't ask anything new from me, so they went downstairs together and went back to the team, I suspect that even if Qiu Bin came over and told them who the murderer was, they would make a noise after hearing the murderer's name, and then do what they should do now.

Although Zhao Yiming's death caused a big sensation in the factory, it is just like the old saying - without anyone, the earth will turn. The daily work in the factory is still carried out in an orderly manner, the processing and production team makes the specified number of processed parts every day according to the production plan as usual, and the transportation department receives it and sends it to various locations on time, even when I was on night duty on Saturday night, I video chatted with Yang Yang, and I was mainly chatting about some things that I would go to next Monday for the interview. It seems that Zhao Yiming is dead, from a living person who will be seen every three or five times and will be bored every time he sees it, to a gag talk after dinner, used to educate every employee in the workshop to kill himself if he commits more injustice, only the appearance of the police from time to time can remind us that this matter is not over.
