My neighbor's name is Conan

Seeing that Aoki Song rejected his reasoning without thinking, Mouri Kogoro immediately asked: "Why is it impossible?"

"If you go by water, it is easy for people to notice this abnormal behavior. And the depth of the water is more than [-] centimeters. If you go by water, there will definitely be a lot of water in Box [-], but I have checked Box No. [-] is very dry and there is no place to get wet," Aokisong said.

After listening to Aoki Song's words, Mouri Kogoro said with some reluctance: "Maybe there are other methods."

Aoki Song thought for a while and said: "This is also possible. To be cautious, Takagi, go to each box and ask if they have seen anyone passing by in the waterway."

"Yes." Takagi Sheba took the order and quickly went to ask people in several other rooms.

It didn't take long for Takagi Shita to come back.

"Police Department, I asked the guests in boxes four, five, six, and seven, and they all said they didn't see anyone passing by the waterway." Takagi Wataru reported.

After listening to Takagi Wataru's report, Mouri Kogoro said in surprise: "What, no one saw anyone passing by in the waterway."

Takagi Sheba nodded: "There were more than four people in each box. No one left, and they didn't see anyone passing by the waterway. They only saw the boat delivering food passing by."

"Could it be diving?" Mouri Kogoro guessed.

"Impossible. The water here is only fifty centimeters deep. It is impossible to dive. Even if you dive there, you will be easily discovered." Takagi Wataru retorted.

Aoki Song also said: "So, it would be impossible to enter by diving. However, since the murderer cannot be someone from outside, he must be a customer inside the restaurant. Now we need to investigate the alibi."

After hearing Aokimatsu's words, Maruda Ayumi opened his notebook and said: "At about [-]:[-], the victim came out of the box on the [-]rd, and at about [-] o'clock, he was found dead in the [-]th. Inside the box, the Forensics Department estimated the time of death to be around [-]:[-]."

"In this case, the murderer was someone who was not in the box between seven-thirty and eight o'clock." Aoki Song thought for a while and said.

Hearing this, Takagi Shepa quickly said: "Just now, I have inquired in the boxes No. [-], [-], [-], and [-]. During this period of time, no one in their boxes has left. They have always been together. While eating, we chatted.”

"That's right." Aoki Song nodded, not surprised by the result.

After all, he had previously felt that the murderer in this case was either Nobuo Iwama or Ryuichi Arai.

So Aoki Song turned to look at the two of them and asked: "Professor Iwama, where were you at [-]:[-]?"

Nobuo Iwama quickly replied: "I have been in box three."

At this time, Mouri Kogoro also intervened: "I remember that at that time, Professor Iwama yelled."

"Ahaha, that's right. I was looking for contact lenses at that time and accidentally knocked over the plate." Nobuo Iwama said sheepishly as he followed Kogoro Mori's words.

Mouri Kogoro added: "After that, I also saw that the window of the third box was closed. This may prove that you were not at the murder scene."

Aoki Song raised his eyebrows and keenly noticed that there was a problem in Mouri Kogoro's words.

It was not that Mouri Kogoro deliberately lied for Iwama Nobuo, but the situation at the time - Moori Kogoro did not see Nobuo Iwama himself!

As a senior scientist, Aoki Song knew a lot about how to create his own alibi in this indirect way.

The simplest is audio recording, which was used in many early cases.

Therefore, no matter how believable it sounds, as long as you don't see the person in person, it may be a trick, and you must be more cautious.

There was some doubt in his heart, but Aoki Song did not ask immediately. Instead, he turned to look at Ryuichi Arai and asked, "What about you, Mr. Arai? You probably returned to the restaurant after the murder happened, right?"

"Yes." Arai Ryuichi responded first, and then quickly explained: "After I went out in Kaneda, the professor asked me to buy a pack of cigarettes for him, so I went to buy cigarettes for him." As he said that, he took out a pack of cigarettes from his trouser pocket.

Then Ryuichi Arai added: "Because the brand of cigarettes that the professor smoked was no longer available in the restaurant, I went to a nearby supermarket to buy them."

Hearing this, Anzai Akiko quickly testified: "Yes, because the brand of cigarettes he bought was sold out in our restaurant. So, I told him the location of the supermarket."

"It took me about ten minutes to walk to the supermarket. I still have the receipt from the supermarket." Ryuichi Arai took out his wallet from his pocket, took out another receipt in the wallet, and handed it to Aoki Song.

Aoki Song took the receipt, looked at it and said, "The time on the receipt is [-]:[-]." And it's also today's date this year.

Seeing this, Mouri Kogoro reasoned: "In other words, both of them have sufficient alibi. So the murderer is only among the other guests?"

Hearing what Mouri Kogoro said, the expressions of Nobuo Iwama and Takashi Arai softened a lot.

Aokimatsu did not answer Mouri Kogoro's words, but looked at Maruta Ayumi aside and said: "Go to this supermarket to verify the situation and see how long it takes to get back and forth."

"Yes!" Ayumi Maruda replied.

Then Aoki Songcai said: "The other guests in the box are all more than four people. It is impossible for the murderer to avoid it, unless the people in the box deliberately concealed it for the murderer."

Gao Musha shook his head and said: "This should be impossible. When I investigated just now, I didn't find anything strange about the people in any of the boxes."

"In this case, Professor Iwama and Mr. Arai, both of you were alone at the time, so there is still suspicion." Aoki Song said.

Arai Ryuichi said nervously after hearing this: "How can we kill Kaneda?"

Nobuo Iwama also said: "Stop joking, how could we be the murderers?"

"It's hard to say. After all, when you came, Detective Maori and I saw that the victim's attitude was very arrogant and he didn't respect either of you." Aoki Song said lightly.

Mouri Kogoro also said: "That's true, but they all have alibis!"

"So I just said that they are suspected, not that they are the murderers." Aokimatsu looked at Nobuo Iwama and Ryuichi Arai and said: "Both of you, please cooperate. Please stay here now and don't move around casually to avoid Cause unnecessary misunderstandings. If you are innocent, we will not unjustly accuse you."

After finishing speaking, without waiting for the reaction of the two people, Aoki Song looked at Akiko Anzai aside and said: "Miss Anxi, please come with me."

"Ah, okay." Anzai Akiko responded. When she saw Aoki Song walking towards box number eight, she quickly followed him in small steps.

Aoki Song asked Anzai Akiko to wait outside the door of box No. [-], and he walked in with Takagi Wataru.

Aokisong has always been biased against the forensic department when it comes to autopsies and murder scene inspections, so he has to do it again himself.

Sure enough, Aoki Song soon found a clue on the victim's body - there was a black substance on the inside of the thumb of the victim's right hand.

"What is this?" Aoki Song pointed there and looked at the criminal in the forensics class and asked.

"According to my preliminary judgment, it should be some kind of caviar." The forensics officer replied.

Takagi Wataru was stunned when he heard this, "Caviar?"

Aoki Song narrowed his eyes and said thoughtfully: "I remember that the most expensive thing in this restaurant is puffer fish caviar."

Thinking of this, Aoki Song quickly called Akiko Anzai in. "Ms. Anxi, please tell me the serving time of each box, do you still remember?"

"I didn't look at my watch at the time, so I'm not sure, but I do remember the order in which the dishes were served." Akiko Anzai replied.

After hearing this, Aoki Song thought for a while and asked: "Box No. [-], do you still remember when the food was served?"

"It was exactly half past seven. It was a coincidence that I happened to look at my watch at that time. Because Professor Iwama and the others ordered a lot of dishes and spent a lot of time making them, I looked at my watch after they served the dishes." Anxi Akiko said.

"Then you should have records of what dishes were ordered in each box." Aoki Song asked again.

Akiko Anzai nodded, "There must be a record, otherwise how will we pay the bill later." They are ordering and serving food here, not a set meal.

"Puffer fish caviar, except for box 3, has no one ordered it today?" Aoki Song asked.

Anzai Akiko shook her head after hearing this, "No one orders it anymore. To be honest, although puffer fish caviar is our signature feature, it is puffer fish after all. The poison content in the roe is higher than puffer fish meat, so not many people order it."

What's more, this thing is expensive and the price-performance ratio is really not high.

Only people who are showing off, or people who really like to eat and are not short of money, will order it.

Real hammer!

One of the two people, Nobuo Iwama and Ryuichi Arai, must be the murderer.

There was puffer fish caviar on the inside of the big finger, which could only have been touched by the victim when he was fighting with the murderer. He was later stabbed to death, so there was no way to wipe it off on his own initiative.

If it wasn't for this reason, how could the victim have kept Big Thumb dipped in puffer fish caviar!Whatever you do like that will easily stain it and it will definitely be wiped off.

Among these two people, the most likely one is Nobuo Iwama.

Because Arai Ryuichi was taken away by Nobuo Iwama to buy cigarettes, Arai Ryuichi also took out the supermarket receipt and there was a high chance that there would be no problem.

Of course, there is no evidence now, so Nobuo Iwama cannot be arrested directly.

And there is an extremely small chance that Akiko Anzai is also the murderer!

Because for now, this case is not a classic choice of three, but a choice of two.

So this thing that is not in line with Ke Xue is because the old 73 thieves rebelled and did it deliberately.

Is there another "one" who has been standing in front of everyone for a long time? This is Miss Anxi.

The two of them seem to be about the same age, so why can't they hate each other because of love?

There are many such cases in "Detective Conan".

Therefore, Qingmusong will not jump to conclusions without evidence.

Even Conan will stand up and reason after he sees through the murderer's modus operandi, knows who the murderer is, and finds evidence.

Aoki Song thought for a while, looked at Akiko Anzai and said, "Miss Anzai, please come with us to Box 3."

"Okay." Although she didn't know what Aokisa was going to do, Anzai Akiko didn't dare not listen to Aokiso.

Aoki Song walked into the box No. 3 with Takagi Wataru and Anzai Akiko. When he saw the things on the table, he was stunned for a moment. He subconsciously turned to look at Anzai Akiko and asked: "Miss Anxi, I remember you said you would be there at half past seven. Is it ready?"

"Yes, I'm sure." Akiko Anzai was stunned when she saw the things on the table, but she still nodded.

what's the situation?

Takagi Wataru was confused.

Seeing this, Aoki Song pointed to the things on the table and asked: "Takagi, what do you think when you see these things?"

Takagi Wataru knew that Aoki Song was not the kind of tormenting boss. Every move he made during the handling of the case had its own meaning. He did not dare to delay and quickly stepped forward to take a closer look. Then he expressed his thoughts, "The puffer fish caviar seems to have been knocked over." Some."

"Any more?" Aoki Song continued to ask.

what else?

Takagi Shita didn't see anything!

Aoki Song rolled his eyes at him, and then called the police officer who was taking photos to come in, wanting to take photos of every place in the house.

Later, Aoki Songcai pointed to the table and said: "The food will be served at half past seven. The body of the victim was found at eight o'clock. It has been half an hour. Except for the overturned puffer fish caviar, none of the products on the table have been touched." .”

"Well, it's normal that people didn't use their chopsticks when everyone was here." Takagi Wataru said weakly.

Aoki Song shook his head, "You are talking about a normal treat between friends, but it is obviously not present. Professor Iwama and the victim are not interested in Mr. Arai now and will not wait for him.

As for Professor Iwama, the victim has been out for half an hour. You can see that the ice on the sashimi has melted a lot of water. If this continues, the sashimi will become stale.Besides, who would be a fool to wait here like a fool when they are having dinner? It only takes less than half an hour to go to the toilet, and he should have gone there long ago. "

Takagi Wataru wasn't stupid enough, but he felt something was wrong after hearing what Aoki Song said.

After giving Takagi Wataru some pointers, Aoki Song ignored him and carefully inspected Box 3.

Then several suspicious points were discovered.

First, the first thing is the overturned puffer fish caviar.

Second, the paper bag with a pair of bamboo chopsticks was missing.

Aoki Song asked Anzai Akiko and found out that they did not take the initiative to clean up the garbage unless notified by the guests.

There are no trash cans in the private room, and these items are placed on the table by default.

Third, Aoki Song found a wet mark on the window frame of Box 3, and there were two small holes in the window frame.
