My neighbor's name is Conan

Takagi Shigeru also agreed: "Yes, even if you take the train, it will take more than 30 minutes."

Aoki Matsu nodded.

Next is the third message, a male voice: I am Inaba from Xingrongguan, I want to ask about the progress of the report that I troubled you to do... Editor-in-chief, what date is it today? ... April 11nd, 28: am... That's it, there is still a week left before the deadline, please keep up the good work! By the way, I don't care about the insider report last time, I still hope you can give me more advice in the future.

The time is: 11:29 a.m., Friday.

"The background sound this time is people talking," said Maruta Ayumi.

Takagi Shigeru nodded. "It sounds like he's calling from the company. Besides him, there seems to be the editor-in-chief and another person."

"Xingrongguan is quite far from here. If you take the tram, you will have to change trains. It will take about an hour to drive there," added Maruta Ayumi.

Aoki Matsu thought about it and felt that this person was more suspicious than the previous two.

why?

Because the time is so accurate!

Generally speaking, people who use the answering machine function of their landline phones as an alibi like to do this. The more accurate and straightforward the time is, especially when it is accurate to the minute and second, the more suspicious that person is.

Don’t ask why, the answer is science.

This person also left a message saying, "I no longer care about the last insider report."

In reality, if you really don’t care about it, you won’t say it at all. But if you say it, it means you care about it in your heart.

It is entirely possible that this was the motive for the crime.

Finally, this is the last message.

It was a female voice: I just contacted you,...

Hearing this, everyone subconsciously looked at Kobayashi Sumiko who was standing next to Shiratori Renzaburo.

The message continues to play: Kobayashi, the head teacher of Class B, Grade 1, Teitan Elementary School... Ahem... I'm sorry, I seem to have hay fever... Ahem... I wanted to ask you for advice again, but I'll wait until we meet... Ahem... See you tomorrow then.

The time is: 11:30 a.m., Friday.

"Chengzi, are you okay?" Upon hearing this, Shiratori Renzaburo asked hurriedly with concern.

Kobayashi Sumiko said in front of so many people, "I'm fine now. I had a good sleep yesterday and I feel much better today."

"This is the teacher's voice, right?" Mitsuhiko asked Kobayashi Sumiko.

"Yes!" Kobayashi Sumiko nodded in response.

Yuan Tai suddenly didn't know what went wrong, and said in panic: "Ah! So the teacher might be the murderer!"

"Eh?" Ayumi suddenly became nervous when she heard that.

"How could the teacher be the murderer!" Sayuri retorted.

Huiyuan Ai said calmly: "The teacher really can't be the murderer. If the criminal was the teacher, she would have taken advantage of being the only adult among us and used this as an excuse to rush into the house and run to the body.

That way, when the police investigate later, even if they find the teacher's hair or fingerprints in the house, it will be easier to find an excuse."

"That's right!" Conan nodded in agreement.

Seeing this, Qing Musong smiled and said, "It seems that Conan has learned a lot from Uncle Maori, and he really put it to use today." Then he walked over, rubbed Conan's little head and said, "Well done, you really helped Mr. Kobayashi clear his suspicion."

As he said this, Aoki Matsu looked at Shiratori Renzaburo with a smile and said, "Shiratori-san, I think based on this, you should treat these children to a big meal later."

Shiratori Jinzaburo had heard about the big dinner that Aoki Matsu invited the Junior Detective Team to after they helped solve the case. Seeing Aoki Matsu's teasing, Shiratori Jinzaburo smiled and said, "No problem. After this case is closed, Sumiko and I will treat you to a big dinner at home."

Hearing this, Kobayashi Sumiko looked at Shiratori Rensaburo shyly and said, "Sanlang..."

"Really? I want to eat eel rice." Yuan Tai said happily.

Seeing this, Qing Mu Song quickly interrupted Yuan Tai's words, otherwise there would be no way to investigate the case. "Well, if you want to have a good meal, you have to solve this case quickly."

Then Aoki Matsu looked at Kobayashi Sumiko and asked, "Teacher Kobayashi, what is the thing you said you wanted to ask me in your message?"

"It's about the children accepting the interview." Kobayashi Sumiko said, "I wanted to confirm it again. At that time, the bell for the fourth period rang. Yesterday, I called Mr. Sugimori at 11:22 after the third period and told him that the children were willing to be interviewed. Then I suddenly remembered this matter, so I called him again, but the call was transferred to the answering machine at that time."

"I understand." Aoki Matsu nodded.

Upon hearing this, Maruta Ayumi immediately reasoned, "So, the criminal must have acted between 11:22 and 30: yesterday."

"Inspector Aoki, according to Mr. Kobayashi's testimony, the time when the call came in was correct, so from 22 minutes to 25 minutes when the first message came in, there were only three minutes." Takagi Wataru said seriously.

Qing Musong nodded and said, "Indeed, the murderer must have killed within these three minutes. The murderer was very skillful."

"That's what I mean." Takagi Shigeru agreed.

At this time, Kobayashi Sumiko suddenly remembered something. "I remembered that when I was talking to Mr. Sugimori on the phone, he mentioned that someone would come to see him in a while."

"Oh!" Everyone looked towards Kobayashi Sumiko upon hearing this.

"Teacher Kobayashi, do you know the other person's name?" Aoki Matsu asked.

Kobayashi Sumiko said apologetically: "I don't know."

Aoki Matsu was not disappointed when he heard this. If he knew who the murderer was so quickly, it would not be a classic choice between three.

"Inspector, what should we do now? Should we call these three people?" asked Maruta Ayumi.

Qing Musong thought for a moment and said, "No hurry. Let's play the messages from these three people slowly first and listen carefully to see if there are any details in them that we didn't notice the first time we listened to them."

In cases like this, questioning the suspect is of no use at all. Even if the other party accidentally lets something slip, it will eventually be confirmed in the voicemail message on the landline.

So play the message again at slow speed, listen to all the details, write them down, and then talk about it. Who knows, you may find evidence directly.

"Yes!"

Then, Takagi Shigeru played the messages from these three people one by one at 0.5 times the speed.

However, just as Takagi Shigeru was about to release the signal, a train passed by the level crossing near Sugimori's house, and the alarm sounded for two minutes.

Aoki Matsu suddenly realized something and immediately said to Shiratori Renzaburo, "Shiratori-san, please check the time at the nearby level crossing. The train passes here at around 11:."

"I understand. I'll contact the tram company right away." Shiratori Renzaburo nodded in response.

After listening to the first message, Maruta Ayumi said, "Inspector, I have just called Nichimi TV to verify. They started broadcasting TV Grand View Garden at 11 a.m. yesterday."

"It sounds like there's no problem, let's move on to the next one," said Aoki Matsu.

"Yes!" Takagi Shige immediately started playing the second one.

After the second message is played.

Mitsuhiko suddenly said, "Brother Aoki, I think the in-car radio is a little strange."

"What's strange about that?" Aoki Matsu looked at Mitsuhiko and said.

Mitsuhiko is very smart sometimes and can even beat Conan occasionally, so Aoki Matsu is willing to listen to him.

"I remember that the announcement on the train usually says: 'Dear passengers, please watch your step when getting off the train', but the message only stops at 'watch'." Mitsuhiko said seriously.

Seeing this, Takagi Shigeru quickly slowed down the video again.

"Inspector Aoki, it's just as Mitsuhiko said. He stopped talking after the word 'pay attention.'" said Takagi Wataru.

"Go contact the broadcasting station manager of Okuho Station and ask about the situation." Aoki Matsu said.

"Yes!" Maruta Ayumi immediately picked up the phone to contact.

Later we learned that the announcer at the Osui Station radio station had a sudden attack of hay fever yesterday and couldn't even make it through one lap of the Toudu Loop Line, so he had to hire someone to take his place just after noon.

The announcer at that time had to hold back a sneeze, so he couldn't continue after saying "Please pay attention".

"In this case, the person who left the second message can be ruled out as a suspect. The other party did not use a recorder or anything like that," said Aoki Matsu.

A sudden attack of hay fever can cause a professional announcer to make mistakes, which is obviously completely uncontrollable.

"Mitsuhiko, you are great. You listened very carefully." Aoki Matsu praised Mitsuhiko. He now drives to and from get off work and has not taken the tram for a long time, so he overlooked this detail. The same was true for Takagi Shigeru, Maruta Ayumi and others.

Being praised by Aoki Matsu, Mitsuhiko seemed very happy "Hehe..."

Aoki Matsu then said to Takagi Wataru: "Let's move on to the next one."

"Yes!"

After the third message was played, no one could hear anything wrong.

In addition, Aoki Matsu felt that the time was too precise, which was suspicious of scientific research.

After the call, Shiratori Renzaburo came out of the room and said to Aoki Matsu and the others, "Aoki-san, I just called the train company to confirm that the train passed by here at 11:24 yesterday, and the alarm sounded for 2 minutes."

"In that case, the first message person can be ruled out as a suspect. Because of Mr. Kobayashi's testimony, it can be confirmed that the murderer did not come to the door until after 11:22, and the victim had already been killed before the first message came in at 11:25.

After the victim was killed, three messages came into the answering machine at 25 minutes, 27 minutes and 28 minutes respectively. This shows that the murderer did not leave the room immediately after killing the person. Instead, he first used a prepared recording as background music in the room, called the landline with a mobile phone, and left messages to serve as evidence of his alibi.

The alarm sounded for 2 minutes, and it started at 11:24, so the person who left the message at 25 minutes must not be the murderer, otherwise there would be an alarm sound in the background sound of her message. "

"The murderer must be Mr. Inaba from Xingrongkan who left the third message!" Maruta Ayumi said excitedly.

Hearing this, Qing Musong looked at him and asked, "Did you get the call records of the landline from the telecommunications company?"

"It has just been delivered." Shiratori Renzaburo handed over a file bag.

Qing Musong took it, opened it, and quickly found the record of 11:29 yesterday morning. "Sure enough, it was called from a mobile phone, not a landline."

"It's strange to ask the editor-in-chief for the time when you have a mobile phone. And if the other party is in the office, he should use the office phone to call," said Takagi Shigeru.

You should know that mobile phones have been displaying time since their inception.

In addition, most companies, under normal circumstances, will not reimburse mobile phone bills.

So if you are making a phone call in the office, in most cases you will use the company's landline to save on your phone bills.

Not to mention, Mr. Inaba called for business.

"That's right." Qing Musong nodded, thought for a moment and said, "Call the editor-in-chief of Xingrongguan and ask about the situation. Also ask if they have asked Mr. Shansen to write an article. In addition, immediately determine the whereabouts of Mr. Inaba and arrest him."

"Yes!" Several people responded.

Then everyone took action immediately.

Takagi Shigeru was responsible for calling the editor-in-chief of Xingrongkan.

"Hello, I'm looking for Mr. Inaba." said Takagi Wataru.

The man who answered the phone replied, "I'm sorry, Inaba is out on business. He should be back soon."

Upon hearing this, Aoki Matsu immediately gave Maruta Ayumi a look.

Maruta Ayumi understood and quickly left the room to make arrangements.

"Excuse me, who are you?" asked Takagi Wataru.

"Ah, I'm the editor-in-chief of Xingrong Pavilion, my last name is Lin." Editor-in-chief Lin replied: "May I ask what you want to talk to him about?"

"I'm Detective Takagi from the First Investigation Division. Do you know where he was around 11: yesterday morning?" asked Takagi Wataru.

Editor-in-Chief Lin was a little surprised when he heard this. "Criminal! This... editors come in and out all the time, so I didn't pay much attention to it."

Takagi continued, "Mr. Inaba left a message on someone's answering machine, and your voice was heard in the background, saying, 'April 11, 28: a.m.'"

"Ah, then I think he was here in the editorial office at the time." Editor-in-Chief Lin answered without hesitation, "Because his cell phone wasn't working very well, he kept asking me about the date and time. I kept telling him to buy a new cell phone, but he never did after a year."

At this time, a male voice came from the phone: "Editor-in-chief, you are going to watch the evening game today, right? Is that okay?"

Editor-in-Chief Lin seemed to be covering the microphone, but the voice could still be heard: "Today is not at the Dongdu Stadium, so I am very worried!"

"I'm not asking about the game, I'm asking about your body," said the male voice.
