"You've been to the township meeting today......

Officer Yokogou confirmed the lady's alibi and the possibility of witnessing the murderer, as is customary.

"Yes, I went to the township meeting at about eight o'clock, and I didn't get home until eleven o'clock."

Madame recalls that this frustrated Yokogou a lot, because for such a long time, she is likely to have completely missed the moment of the crime.

"That is, you didn't witness a possible suspect visit at all?"

"No, actually, I've met the first person to visit......"

Madame recalls that when she went out with her next-door neighbor, she happened to meet a student who came to visit the professor.

"I remember, he should have the last name Hosoya."

"Okay, then please bring this Mr. Hosiya here."

Officer Henggou instructed the officers on the side, and immediately began to ask for other clues.

It is not difficult for the police to find the person surnamed Hosoya who came over tonight.

…………

"So, have you seen anyone else visiting?"

"Except for Mr. Asasa who called around eight o'clock, the rest of the visitors I only knew were students of the professor."

"Could it be...... Can we just check all the professor's students? ”

Officer Henggou was a little difficult, and the professor had taught hundreds of students, if not a thousand, but a hundred, so if he checked them one by one, he would not be able to let the real culprit find a chance to abscond in fear of crime.

"Why don't you look up that."

Katayama stood outside the door and pointed to the landline on the ground.

"You mean ......"

"There is a message on it, check who has left a message, maybe you can find any clues."

"Oh...... That's right. ”

Officer Yokozo listened to what Katayama said, nodded immediately, and took the landline out from under the book with gloves.

The message above is still flashing, indicating that there is indeed a message.

In fact, Katayama originally planned to persuade the police to check the call records, and according to Japanese etiquette, they would probably call first to explain.

But he really doesn't know if the landline can check the call history, most likely not, so he said to simply check the message.

I didn't expect there to be.

………

"There are currently thirteen messages."

The mechanical sound of the phone came out, and there were actually thirteen messages, if it was thirteen people, then the range was not small.

However, Katayama thinks it's unlikely, it should be three times for two people, after all, Conan's case is always one of the three classic choices.

"So, the first pass ......"

Henggou clicked the play button, and the first message was played.

"Hello, Professor Hirota, I'm Shirakura, and the book we made an appointment with tonight is right?"

Then there is more than ten seconds of white space.

The young man's voice came from inside, and it seemed that he should be a recent college graduate at most.

"What is this white warehouse?"

"Oh, he's a young student of my sir......"

Conan was also listening, and when he slipped back from Katayama, he and Zoro followed suit.

"Strange, why did he leave so much blank space in this message......"

After listening to the first message, Conan has only this one idea at present, and it is also the only doubt.

"Hello Professor, I'm Morioka, what time should I come over tonight?"

A slightly thick male voice came out, and Katayama felt that it was most likely a greasy uncle.

"This Morioka again?"

"He was one of my husband's first students, and he would often come to our place to play......"

While Officer Yokozo was still asking, a young man in a jacket walked between Katayama and Conan with his hands in his pockets, and walked between the two of them nonchalantly.

"Excuse me, what's wrong?"

The man looked at so many people here, and was a little puzzled, judging from the voice, it should be Bai Cang.

"It's Professor Hirota, who was killed today......"

As Yokogou was talking, another message was automatically played.

"Professor Hirota, I'm Shirakura, because there is a sudden emergency tomorrow, so I'll come to you today after reading it. Oh, and ........."

"Mr. Shirakura left a total of 10 messages, and Mr. Morioka sent 2 messages...... Mr. Shirakura, don't you think your words seem to be a bit too much? ”

"That's why I called the professor like this, and he didn't answer or reply to the message, so I came here!"

Bai Cang was a little anxious, and hurriedly explained the reason why he left so many messages.

It makes sense.

"Well, this is the last ......"

The content of the first twelve calls is almost the same.,It's basically some words that want to visit the professor.,So Henggou didn't care too much.。

"Hello, this is the insurance company'........."

The content that seems to be irrelevant to this case made both Katayama and Conan stunned.........

This voice is clearly ...... Vodka!

"Here's a new insurance package for you, I think I'll call you again tomorrow."

With that said, the phone hung up.

"It's an insurance salesman......" Henggou watched the message play, and he breathed a sigh of relief, it seemed that the suspect was within three people.

However, Katayama and Conan were in a heavy mood, it was 100% vodka's voice, and it couldn't be wrong, but why did he call the professor......

Could it be that this case was really organized and a vodka masterpiece?

"No, it's not."

Conan thought about it again and denied this possibility, if he wanted to kill someone, it was impossible to leave his original voice as evidence.

And they don't need to make the illusion of a secret room at all.

In other words, they are just testing the professor, and they have not officially come to recycle the magnetic sheets, so the data in the computer is emptied, and it is not the organization's doing.

………

"What? You say Professor Hirota was killed? ”

"How is it possible, I saw him not long ago."

Mr. Hosoya and Morioka were brought here by the police for questioning, and when they heard the news of the professor's death, they both had expressions of disbelief.

"Mr. Hosoya, I think you'll be visiting the professor at eight o'clock."

Yokozo looked at Hosaya with round-rimmed glasses, and according to Mrs. Hirota's testimony, he was the first person to visit......

"That's right, because my daughter wants to apply for Nanyang University, so I want to come over and ask the professor...... Write a letter of recommendation......"

Mr. Hosoya said with some weakness, and Katayama quietly spat out a mouthful of phlegm disdainfully...... This girl wants to come to the professor and go through the back door, and it's called a letter of recommendation...... I'm afraid that the envelope is full of tickets.

I didn't expect this to happen in Japan...... emmm, think about it, too, where there are people, there will be a volume king, where there is a volume king, there will be competition, and where there is competition, there will be shortcuts......

After all, it's all the same in that country.........
