In terms of eating habits, the difference between the north and the south has always been relatively large.

The food plate in front of the northerners is used to put vegetables, bones, fish bones, etc., will be placed directly on the table, or napkins. The bowl is specially used for soup.

In the area near the boundary between the north and the south, the dish is also divided into two parts, one half for vegetables and the other half for food scraps.

The food plate in front of the southerners is a bone plate, which is specially used to store food scraps such as bones and fish bones. The bowl is used for food.

If you eat in a high-end hotel, the restaurant will prepare two plates, one large and one small, for the guests, generally the small plate is used as a plate for dishes, and the large plate is used as a bone plate for food scraps.

Traditional Peking cuisine doesn't produce much food scraps, so there are not too many food scraps left in diners' bone plates.

Ho Ka-fai looked at the deceased's plate in the photo, and a possibility had already appeared in his mind.

Then He Jiahui found another photo, which was a photo taken by the forensic forensic team on the entire table before the test, and it was very clear what dishes were on it.

"Cheng sir, I want to ask the witnesses who ate at the same table again." He Jiahui said to Cheng Feng.

"Have you found a new clue?" Cheng Feng asked.

"It's not certain yet, and the witnesses need to be questioned to know if I'm guessing in the right direction." He Jiahui said.

"Okay, I'll call the witnesses." Cheng Feng nodded.

He Jiahui said: "Let's start with that Xiao Jiaming first." ”

Xiao Jiaming was brought over again, and He Jiahui said directly: "Mr. Xiao, we have to ask a few additional questions." I see that your dishes today are relatively rich, many of them are Beijing's specialties, and the person who orders the dishes should be very discerning. ”

"We're all involved in ordering food! There is a small stir-fried yellow beef, which I ordered. Xiao Jiaming replied.

"So everyone ordered a dish or two?" Ho Ka Fai then asked.

"Not everyone is ordering. Some people look at the menu and feel that they don't like it, or maybe they have already ordered it by others, so they don't order it again. Cai Jiaming replied.

He Jiahui then asked: "Did you start ordering food again after you were all together?" ”

Cai Jiaming thought for a while, and then shook his head: "No, when I came, Du Qiusheng and Zhang Baiqiang had already arrived, and then they gave me the menu and asked me to order. ”

"Manager, please bring this à la carte menu." He Jiahui turned his head to the manager and said.

The manager quickly found the menu, and He Jiahui handed the menu to Cai Jiaming and said, "Mr. Cai, which dish did you order, please mark it." ”

"Okay. I ordered this small stir-fried yellow beef, and I also ordered this lotus seed soup. Cai Jiaming replied.

He Jiahui took the note, and then asked, "Mr. Cai, do you remember where you were seated at that time?" ”

"Remember, I sat in that position inside, my left was my girlfriend, on my right was Ouyang Junxiong, next to Ouyang was Zhang Baiqiang, Zhang Baiqiang's girlfriend, Du Qiusheng, Liu Zhuoyang, Liu Zhuoyang's girlfriend." Cai Jiaming replied.

He Jiahui marked the seats of eight people in the notebook, and then asked: "In other words, Du Qiusheng and Liu Zhuoyang are the closest to the passage, and the deceased is sitting in the position inside." ”

"Yes." Cai Jiaming nodded.

He Jiahui continued to ask: "Mr. Cai, you and the deceased have been old friends for more than ten years, you should have a certain understanding of the deceased's living habits, right?" ”

Cai Jiaming nodded: "I know better." The five of us usually talk about everything, and there are almost no secrets between each other. ”

"Did the deceased have any allergies to anything? Like peanuts? He Jiahui then asked.

"Sir, how did you know that Ouyang Junxiong is allergic to peanuts?" Cai Jiaming asked with some surprise.

"In other words, the deceased is not allowed to eat peanuts and peanut products?" Ho Ka Fai then asked.

"Of course, if you are allergic, how to eat peanuts, if you don't get it right, it will be life-threatening. He usually pays attention to it when he eats. Cai Jiaming nodded and replied.

He Jiahui's eyes narrowed slightly, and Cai Jiaming's confession really confirmed what he thought in his heart.

Then He Jiahui said: "Mr. Cai, I have already asked all the questions I want to ask, thank you for your cooperation." I ask you to keep these questions confidential and not to tell anyone else. ”

"Okay, I'm not going to tell anyone else." Cai Jiaming agreed to come down.

Cai Jiaming was taken away, and Cheng Feng asked, "Who is next?" ”

"Cai Jiaming said that he was the third to arrive, and when he came, he asked Du Qiusheng and Zhang Baiqiang that had already arrived, so let's ask Zhang Baiqiang first!" He Jiahui said.

Zhang Baiqiang was called, and He Jiahui still asked about ordering food.

"When I came, Du Qiusheng had already come, he gave me the menu and asked me to order, I saw that there were already several dishes on the menu that had been ticked behind, it should have been ordered by Du Qiusheng." Zhang Baiqiang asked.

He Jiahui took the menu again and asked, "Mr. Zhang, which dish in this menu did you order?" ”

Zhang Baiqiang told He Jiahui what he ordered, and He Jiahui looked at the remaining dishes on the menu,

Then He Jiahui asked where everyone was sitting, which was also consistent with Cai Jiaming's description. Later, Ho Ka Fai asked again whether the deceased was allergic to peanuts, and he got the same answer.

Immediately afterwards, He Jiahui asked Liu Zhuoyang again.

"My girlfriend and I were the last, and when I arrived, everyone else had already sat down, and they gave me the menu and asked me to order, and I looked at it, and they had already ordered many dishes, so I didn't order, so I just asked the waiter to serve the food." Liu Zhuoyang said.

"Then you were the last to sit outside near the passageway?" He Jiahui asked.

"At that time, there were only two empty seats left, and my girlfriend and I sat down directly." Liu Zhuoyang replied.

He Jiahui asked the deceased about peanut allergy again, and Liu Zhuoyang also gave the same answer.

At this point, three of the four friends of the deceased have been questioned, and only Du Qiusheng, who was invited this time, has not yet been questioned.

He Jiahui didn't ask Du Qiusheng immediately, but called Gao An over, pointed to the photo of the dining table on the digital camera, and asked: "Gao sir, the location of the cyanide found on the back of the turntable, is it under these dishes?" ”

"Let me look at the records." Gao An took out the forensic record and glanced at it, then nodded: "That's right, it's in this position, He sir, how do you know!" ”

"Because I've cracked the murderer's methods!" He Jiahui took a deep breath and said to Cheng Feng next to him: "Cheng sir, call Du Qiusheng, prepare another one and arrest someone!" ”

"Arrest? You mean to arrest Du Qiusheng? Cheng Feng asked.

He Jiahui nodded: "That's right, Du Qiusheng is the murderer!" ”

……

Du Qiusheng was called over for questioning by the police.

"Mr. Du, according to your friend's account, you were the first to come to today's dinner?" He Jiahui asked.

"I'm in for a treat, of course I have to come first, I can't let the guests wait for me!" Du Qiusheng replied.

"You ordered several dishes before the others came?" He Jiahui asked again.

"The waiter brought the menu, and I ordered a few dishes, all of which were specialties here. And I was worried that the roast duck needed to be ordered, so I ordered one first. Du Qiusheng replied.

"That Beijing specialty belly, old Beijing mixed eggplant, and Qianlong cabbage, you also ordered it, right?" He Jiahui asked.

"I read that it is written on the menu that these three dishes are the specialties of this restaurant, and when you come out to eat, you naturally have to taste the specialties." Du Qiusheng asked.

"You also used these three dishes to poison the dead, right?" He Jiahui asked coldly.

Du Qiu was startled, and then said calmly; "Sir, I don't understand what you're saying."

He Jiahui had already guessed that it was impossible for Du Qiusheng to confess, so he explained: "The murderer put cyanide on the back of the turntable, and then was touched by the deceased.

Later, when the deceased ate the roast duck, he took a small cake with his hand, and the small cake was stained with cyanide on the deceased's hand, causing the deceased to be poisoned. This is the method of committing the crime that we have deduced based on forensic tests.

But there is a problem with this, the place on the back of the turntable is only three centimeters by two centimeters, and the deceased's hand needs to touch this small area to get cyanide.

So I've been wondering, how did the murderer make the deceased happen to touch such a small area stained with cyanide? It wasn't until I saw the deceased's plate that I figured it all out.

In the deceased's dinner plate, there is no trace of sesame sauce, but there are three dishes on the table with sesame sauce, one plate is Beijing's special belly, which needs to be eaten with seasoning, this seasoning contains sesame sauce, and the other two plates are old Beijing eggplant and Qianlong cabbage, which also contain sesame sauce.

Sesame sauce is easy to get on the plate, as long as the deceased puts the dish stained with sesame sauce on the plate, then the plate will inevitably get sesame sauce. However, there was no trace of sesame sauce on the deceased's plate, which means that the deceased did not eat these two dishes.

And bursting belly, mixed eggplant and Qianlong cabbage, are all specialties of this restaurant, as you said, you must taste the specialties when you come out to eat, even if you don't like it, you will taste it a little!

And the deceased did not eat the special dishes at all, and the explanation I can think of is that the deceased did not want to eat these three dishes, but he could not eat them at all!

It's understandable that some people aren't used to eating it, but eggplant and cabbage are the most common vegetables, so no one should avoid them, right? Even if the deceased doesn't eat belly, then it's okay to eat a few bites of eggplant and cabbage, right?

So I speculate that the problem is not with the belly or eggplant cabbage, but with the adjuncts of these two dishes, which is sesame sauce, which is used in both dishes.

At first, I thought it was because the deceased didn't eat sesame sauce, but then it suddenly occurred to me that it wasn't the problem of sesame sauce, but the problem of peanuts, and the deceased should be allergic to peanuts.

When I was eating below, the waiter once asked me if I was allergic to peanuts, because the Qianlong cabbage was made with Erba sauce flown from Beijing, and Beijing's Erba sauce was made with sesame sauce and peanut butter.

If the deceased was allergic to peanuts, then he could not eat Erba sauce, and he could not eat the three dishes of bursting belly, eggplant and Qianlong cabbage. So I asked your friend and confirmed that the deceased was indeed allergic to peanuts.

I checked the photos of the table again and found that the three dishes of bursting belly, old Beijing eggplant and Qianlong cabbage were put together. I asked forensic evidence again, and the area where cyanide was found on the back of the turntable was exactly where the three dishes were found.

Obviously, the murderer used these three dishes to complete the poisoning. He applied cyanide to the back of the turntable corresponding to the two dishes, and then, during the meal, turned the turntable and aimed the three dishes at the deceased.

Since the deceased was allergic to peanuts, he obviously could not eat these three dishes, and when he found that he could not eat the three dishes in front of him, he could only turn the turntable, and since the turntable was already full of dishes, he could only reach under the turntable and turn the turntable.

This makes it easy for his hands to get cyanide. And in the process of eating, the murderer can perform this act several times, turning three dishes containing peanut butter to the deceased, and the deceased will turn the three dishes away.

Even if the area stained with cyanide is only three centimeters by two centimeters, if you repeat it a few times, the deceased's hands will definitely be stained with cyanide! ”

"I see!" Cheng Feng nodded suddenly, and there was a little more admiration in his eyes when he looked at He Jiahui.

However, Du Qiusheng opened his mouth to retort: "Then why do you say that I am a murderer? I am not the only one who knows that Ouyang is allergic to peanuts! Everybody knows that. ”

"I asked in detail just now, but no one else ordered the three dishes of Beijing belly, old Beijing eggplant and Qianlong cabbage." He Jiahui said.

"Even if I ordered these three dishes, it doesn't prove that I poisoned them. The three dishes I ordered are all Beijing's specialties, and many people will order them when they come here to eat, and it's normal to order special dishes, don't believe you to look at the tables around! Du Qiusheng continued to argue.

"But it's not a normal thing for these three dishes to be put together. You've ordered so many dishes, why are these three dishes with Erba sauce placed together? He Jiahui said.

"The waiter put it like this when he served the food, what does it matter to me!" Du Qiusheng snorted coldly.

He Jiahui opened his mouth and said: said; "I asked where you were seated, and you sat near the aisle, which means that the waiter would be standing next to you when the food was served.

At this point, you only need to turn the dial to a specific position to guide the waiter to the place you need.

For example, if you see the waiter serving a plate of Qianlong cabbage, then you turn the old Beijing eggplant to the waiter, and the waiter will naturally place the Qianlong cabbage next to the old Beijing eggplant.

You are the only one in the room who can do this, and the others are so far away from the waiter that they may not be able to see what the waiter is serving! ”

"In addition to me, Liu Zhuoyang also sat in the position by the passage! He may also see the food served by the waiter! Du Qiusheng continued to argue.

But Liu Zhuoyang was the last, and he didn't order either, he didn't know that in today's dinner, there were three dishes that contained peanut butter that the deceased couldn't eat! So it's impossible for him to devise this murderous method! ”

He Jiahui paused, and then said: "You chose this restaurant, and you ordered the three dishes containing sesame paste, and you were the first to arrive, and you deliberately chose a location close to the passage. Among all of them, you are the only one who has the ability to carry out this set of murderous methods, so the murderer must also be you! ”

Thank you for your concern, my stomach is much better. Thank you for subscribing!
