My neighbor's name is Conan

It shouldn't be said to be a small hole.

Rather, they are small holes, like those that were pierced by something the size of a needle and then left behind.

Just as Aokimatsu was looking at the window frame and brainstorming in his mind, Ayumi Maruta walked in, "Police department, I just went to that supermarket with Kamijima. The sales clerk in the supermarket had an impression of Mr. Arai. The one-way journey from the restaurant to the supermarket is about eight minutes.”

"Thank you for your hard work," Qingmusong said.

Speaking of this cigarette, Aoki Song had a question that he had forgotten to ask Akiko Anzai. Now he remembered it and asked quickly: "Ms. Anzai, I would like to ask you a question. The kind of cigarettes that Professor Iwama smokes in your place." Are the sales good? Are they gone before eight o'clock?"

Anzai Akiko heard this and said quickly: "The sales volume of that brand of cigarettes is just like that. In fact, it is because today is Wednesday, and we all purchase goods on Thursday. So on Wednesday, except for ingredients, other things are slightly lacking. Iwa The brand of cigarettes Professor Jian smoked was bought by a customer in the afternoon."

After hearing this, Aoki Song continued to ask: "Did you buy the last pack, or is the other party determined to buy all your inventory?"

Anzai Akiko was stunned when she heard this, and then said thoughtfully: "I bought all the inventory, but there were only three packs left at that time, so I didn't find it strange."

Nobuo Iwama is suspected +1.

By the way, this old man has a lot of suspicions, and all kinds of evidence point to him.

Aoki Song boldly assumed that he was the murderer.

But there is still one most important question here - how did the murderer enter Box 8, kill the victim, and then escape.

Assuming Akiko Anzai did not lie, the murderer was not her, but Nobuo Iwama.

He should have gone to Box 8 and killed the victim after sending Arai Ryuichi away.

Then how did he get to box 8?

If you walk along the waterway, you will definitely be discovered.Go to the atrium and you will see Akiko Anzai.

There are no secret passages among the eight private rooms in the restaurant.

How did he get there?

Teleport?

Space jump?

Do you really think everyone is Koizumi Hongzi?

Moreover, in this age of law-ending, Aoki Song felt that Koizumi Hongzi probably didn't know how to teleport and jump in space, otherwise there would be no need to ride a magic broom.

It is obviously impossible for Nobuo Iwama to have magic.

How could he go from box 3 to box 8 when he didn't know magic?

After eliminating all possibilities, no matter how bizarre the final result is, it is probably the correct answer.

After ruling out many methods, Aoki Song came up with a possibility - a boat for serving dishes!

However, this is just Qingkisong's guess and needs to be tested on the spot.

"Miss Anzai, please take us to see the boats used for serving food." Aoki Song looked at Anzai Akiko and asked.

Although she didn't know what Aokimatsu was going to do or what her purpose was, Akiko Anzai had a clear conscience and immediately agreed, "Okay, please come with me."

With that said, he led Aoki Song and others to the back kitchen. After passing the chef's lounge, Anzai Akiko walked to the back, took out a pack of keys, opened the door, and then stepped aside, "The police department is here."

"Is this door always locked?" Qingmusong asked.

Akiko Anzai nodded, "Yes, so no one will come in casually. I am the only one among the restaurant staff who has the key."

Aoki Song nodded, indicating that he understood, and then walked in with Takagi Wataru and others.

There is a large pool connected to the waterway, with five boats, one large and four small, parked neatly on it.

I didn't think it was a big boat when I served the food before, but now it looks quite big. Even if an adult is sitting in it, it won't capsize or sink.

Aoki Song directly targeted the big ship and walked over. As soon as he got closer, he immediately discovered that there was a black stain on the deck of the ship.

After asking someone to take a photo, Aoki Song stepped forward to check it out. It was puffer fish caviar.

This discovery shocked Aokimatsu. It seemed that his direction of investigating the case was correct. Akiko Anzai had nothing to do with the victim. Nobuo Iwama should be the murderer.

Aoki Song thought for a while and then turned to look at Anzai Akiko and asked: "This ship has served several guests in the private rooms since we came in. When was it approximately served?"

Akiko Anzai thought for a while and said: "I remember that after you guys came in at the police department, this ship served food to those in Box 1 and Box 3. The one time in Box 3 was at half past seven, and the other time was to deliver whiskey. At eight o'clock, this is what Professor Iwama ordered. I didn't pay attention to the specific time when the food was served in Box 1, but after Mr. Arai came out to buy cigarettes."

Aoki Song nodded, and then asked the criminal from the forensics department to come forward to see if the deck of the ship could be taken apart.

The Forensics Department made some tinkering and demolished the deck of the ship.

There is only a small motor and sensor below the deck. This sensor can also control the switch of the ship. In addition, after discarding these two things, there is still a lot of space in the hull of the big ship.

Aoki Song thought about it and felt that it would not be a problem to stuff Nobuo Iwama in.

"Police department." The forensics department interrupted Aoki Song's reasoning.

"What's the matter?" Aoki Song asked subconsciously.

The criminal from the forensics department pointed to a place in the boat and said, "Police department, look, there is a short hair here."

Qing Mu Song's eyes lit up, he had short hair and good stuff, isn't this irrefutable proof?

It seems that Nobuo Iwama didn't expect that he would suddenly lose his hair inside.

Ke Xue!

This must be Ke Xue.

"Take pictures and put them away. This is likely to be evidence to identify the murderer." Aoki Song said.

"Yes!"

Afterwards, Aoki Song walked out of the kitchen and walked towards Nobuo Iwama and Ryuichi Arai.

"Police officer, how long do we have to stay here?" Nobuo Iwama saw Aoki Song coming over and quickly stepped forward and asked.

Aoki Song said with a smile: "I have one more question to ask you. After I ask it, you guys will cooperate with us in searching the items you carry, and then you can leave."

search! ?

Mouri Kogoro and Conan immediately became energetic after hearing this. They are also quite familiar with Aokimatsu's habit of handling cases. Generally speaking, if you want to search someone, it means that the other party is most likely the murderer, and he has foolishly hidden the evidence on his body. .

There are always some people who are deeply influenced by certain literary works and believe that "the most dangerous place is the safest place" and put evidence on themselves that can kill them.

Therefore, after Aoki Song said this, both Mouri Kogoro and Conan carefully observed the expressions of Nobuo Iwama and Ryuichi Arai.

Sure enough, I noticed that Nobuo Iwama's expression was a little abnormal.

I saw him become nervous instantly, and subconsciously said with great resistance: "You want to search the items we carry? Why is this? This is not necessary."

"Of course it's because you had the motive to kill the victim, and you took the initiative to invite the victim here to celebrate today, but the victim died here. There is no coincidence in our police department, only necessity, so you two are suspected. "Qingmu Song said seriously.

Nobuo Iwama asked angrily when he heard this: "Is it strange that we celebrate our colleague's promotion to associate professor?"

Although what Aoki Song said was not unreasonable, everyone agreed with what Nobuo Iwama said.After all, it would be weird to celebrate a colleague if it also arouses suspicion.

Aoki Song chuckled and said: "It's nothing to celebrate a colleague's promotion to associate professor. It's just that you obviously don't like him and still hate him, but you want to celebrate him. This is strange. Mr. Arai will be the victim's assistant in the future. , it’s understandable that he is helpless, but as a professor, you have to please him, which is strange.”

Nobuo Iwama's heart tightened when he heard this, but he still held on and said: "I'm treating him to celebrate. Does this count as trying to please him? This is a bit inexplicable. I'm just his senior, just to be able to Encourage him and make him work harder. In addition, we will work together in the future, just to build a good relationship with each other."

"I'm afraid only the three of you know what the reason is." Aokimatsu did not continue to talk nonsense with Nobuo Iwama, but looked at Ryuichi Arai aside and asked: "Mr. Arai, I would like to ask you, what are you talking about? Before you went to buy cigarettes, was the victim never in box 3?"

Ryuichi Arai nodded quickly after hearing this: "Not long after we entered Box 3, Kaneda went out. When the food arrived, I asked the professor, where did Kaneda go? The professor said he might have gone to the toilet, so I I didn’t ask any more questions. Kaneda didn’t come back until the professor asked me to help buy cigarettes.”

"I understand. After checking the items you carry with you, you can leave." Aoki Song said to the two of them with a smile.

Arai Takashi didn't care. He had done nothing bad and was not afraid of police inspection. He cooperated very well and let Takagi Wataru search him.

After Iwama Nobuo hesitated for a moment, he may have been betting that the police would not be able to see through his murderous methods, so he also asked Maruta Ayumi to search him.

Nothing was found on Arai Ryuichi. Handkerchiefs and wallets were all items normally carried with him.

Nobuo Iwama had a lot of messy things on his body - a portable tape recorder, rubber bands, soaked and damaged bamboo chopsticks and paper bags, and pins.

And——the puffer fish caviar on the shirt under the suit, on the left wrist.

"What is this?" Mouri Kogoro was dumbfounded.

【This time we are really alive!The evidence was also found, and it was irrefutable! 】

"It should be a crime prop." Qing Mu Song said very calmly.

"Crime props?" Everyone was stunned. After reacting, they looked at Nobuo Iwama and subconsciously stayed away from him.

"What do you mean by this? You can't solve the case, so you just find someone to slander you?" Nobuo Iwama said with an ugly face: "I have been in Box 3 all the time, and Detective Mori can prove it to me."

Aoki Song shook his head when he heard this and said: "No, Detective Maori only heard your voice from beginning to end, and did not see you. Mr. Arai went out to buy cigarettes, and he had the receipt and the supermarket salesperson to prove it. But Maori The detective didn't see you, so maybe it wasn't necessarily the recording you played at that time."

Hearing this, Nobuo Iwama quickly explained: "I do have a small tape recorder, which I prepared for class. If I come across an idea, I will also use the tape recorder to record it."

Although Mouri Kogoro believed in Aokimatsu's judgment, he still said with some doubts: "It is indeed possible to use a tape recorder, but I also saw that the window was closed at that time."

After hearing what Mouri Kogoro said, Aoki Song pointed to the messy things that were searched from Nobuo Iwama's body, "He just used these things to achieve his own goals."

Before Nobuo Iwama could quibble, Aoki Song said: "First, nail a thumbtack on the left window frame and the window, fix the rubber band on the thumbtack, use the paper sleeve for chopsticks to roll into a circle, and wrap the paper sleeve One end is nailed to the right side of the window frame, and the other end is nailed to the right side of the window where the rubber band is nailed.

Then put an ice cube in the circle of the paper sleeve and you're done.After the ice melts, the paper cover is soaked in water, and the rubber band causes the paper cover to break, and the window will be automatically closed immediately under the action of the rubber band.

The chef here said before that Professor Iwama has been to this restaurant many times, and every time he comes, he orders a lot of food, but he rarely eats those dishes.I think you must have been very precise in preparing for today's killing. "

Nobuo Iwama's heart sank when he heard this, but he did not give up and struggled to say: "This is all your guess. The water stains you mentioned were just accidental stains when I closed the window." Spread the water in the cup there.

And the tacks and the marks you mentioned were not done by me at all. Maybe they were done by someone else, but they just happened to happen to me.If you can't find the murderer, then you blame me. If you say it was me who killed him, then please provide evidence. "

"Of course I have evidence that you committed murder. Before that, I will briefly describe the entire process of your murder and then present the evidence."

Aoki Song didn't wait for Nobuo Iwama's reaction and continued directly: "First tell the victim that you have something to discuss with him, but you don't want others to know. So he asked the victim to reserve box No. 8 here.

Then, when he arrived, you quietly told him to wait in box No. 8, and then after ordering, you deliberately asked Mr. Arai to buy cigarettes, and you still deliberately asked him to buy cigarettes in the restaurant this afternoon. The brand has already been sold out.

I asked Miss Anxi that someone deliberately bought all the cigarettes of that brand this afternoon.As a result, Mr. Arai had no choice but to go to the supermarket to buy it.

So you had time to be alone in the box, and then just like the arrangements I just mentioned, you set up the mechanism that you thought you could fool our police, implying that you were always in Box 3. "
