In Professor Hirota's study.
Officer Henggou was searching with Conan for the phone message in the call message.
Maybe you can find some interesting clues in the content of the message.
First of all, the first person to leave a message was Mr. Bai Cang.
The second message was from Mr. Sheng Gang.
The general meaning of their messages was that they were asking Professor Hirota if he had time now.
When police officer Henggou asked Mrs. Hirota who Mr. Shiracang was.
Conan discovered that there were signs of stumbling on the tape.
Yuyuki Agasa saw a handsome man wearing brown jeans standing behind him.
Then, the handsome man took the initiative to introduce: "I am Mr. Bai Cang. May I ask what's going on?"
Officer Henggou told Mr. Bai Cang what happened today.
After hearing what Officer Henggou said, Mr. Shirakura had a shocked expression on his face.
Officer Henggou looked at his shocked expression.
He asked Mr. Shirokura: "There are too many messages to Professor Hirota today. Of the thirteen messages, you took up ten. And in the second last message, you said that you have something to do tomorrow and can only come here tonight." .Can you explain it."
Mr. Shirakura looked at Officer Henggou's questioning expression.
So he explained: "It was because of my last message that I found Professor Hirota didn't answer, so I came here late at night."
After hearing his explanation, Officer Henggou thought for a while.
So he nodded in agreement.
Then, he said to Conan: "This is my last message now. I hope it can be of some help."
But soon, after listening to the last message.
Officer Henggou said in a disappointed tone: "There's nothing wrong with this. Isn't it just a message from the insurance company?"
Conan heard that it sounded like vodka.
And Haibara Ai walked up to Conan and said to Conan: "That sound is the sound of vodka, but it's not necessarily him who killed Professor Hirota."
When Conan and Haihara Ai were discussing who was the most suspect in this case.
Two more people came to Professor Hirota's home.
One of them is Mr. Hosoya, who is wearing a dark green suit and glasses.
The other one is Mr. Sheng Gang, who is fat and wearing a dark blue sweater.
After hearing what Officer Henggou said, they had surprised expressions on their faces.
And they said that when they left.
He's still fine.
At the same time, Mr. Sheng Gang said to Officer Henggou: "I came to ask him to write a letter of introduction to Nanyang University for my daughter. I remember that when I left, he was still fine. And when I left, he was I drank a lot of wine."
Officer Henggou saw it behind the red wine bottle placed in front of the computer desk.
Nod in approval.
Mr. Sheng Gang pointed to the chess pieces scattered on the study floor.
He said that he even played chess with Professor Mitsuda.
But I didn't play the next game with him.
But when I came to the study at 9:30 in the evening.
I found the study door locked.
So I can only go back.
After Officer Henggou sorted out the reasons why he went to Professor Hirota provided by the three people.
Then he asked Professor Shiracang: "You just arrived here, and what is your purpose of coming here?"
Mr. Shiracang replied to Officer Henggou: "The purpose of my coming here is to take away the embarrassing photo of me and Professor Hirota. The embarrassing photo he took at that time."
After hearing Mr. Shirakura's explanation, Officer Henggou nodded to express his understanding.
Officer Henggou thought of this and asked Mr. Bai Cang directly: "I think the most suspicious person is you, Mr. Bai Cang."
Mr. Bai Cang saw Officer Henggou’s question.
He hurriedly asked: "Tell me, what is my purpose of killing him. And how did I handle the secret room murder case."
After hearing this, Hiroshi Agasa asked him: "Well, even if the murder has nothing to do with you, I'm afraid you are the only person who can skillfully control a computer. Besides, Mr. Sheng Gang and Mr. Hosaya, they don't seem to know how to do it." Let’s operate the computer.”
At the same time, police officer Henggou also questioned Mr. Shirakura: "Didn't you say that it's because Professor Hirota recorded embarrassing photos of you at school? And you are now in a critical period to obtain a graduate degree at the University of Tokyo. If Professor Hirota takes this thing , if you tell the University of Tokyo, your dream will be ruined."
After hearing this, Mr. Bai Cang said with a red face: "Since you said that, then find the evidence."
When Mr. Shirakura said this, Mr. Henggou immediately expressed silence.
Conan suddenly discovered a problem, that is, the gap in the door was just right enough for the key to pass through smoothly.
And why were there two books placed on both sides of the phone?
Also, why is there a blank part in the message on this tape?
And the time in this blank part is too long.
The most ingenious part is the blank part of the tape.
It happens to be the section where the strap is damaged.
So, I thought of Conan here. Started to enter a state of thinking.
Hiroyuki Agasa saw Conan's thinking state and said to Conan: "I felt something. I felt that the cause of his death was not the fallen desk, but the trophy. And if the murderer used the message function of the landline phone, and then added Why is the damaged tape of this tape so strange? And..."
Conan suddenly thought of something.
So he took the initiative to say something to Agasa Yuyuki.
So Agasa Hiroyuki took the initiative and said to Officer Henggou: "I discovered the other party's murder method! First, we pulled out a long section of the tape. Then..."
Afterwards, Hiroyuki Agasa and Conan began to use the props in the study.
Start doing your own experiments.
First, Conan was in the hands of forensic investigators.
Get out a brand new blank tape.
Of course, Officer Henggou expressed his confusion.
However, Arisaki saw the confused look on Officer Henggou's face.
He hurriedly said that this was not the point.
Then he began to stretch the tape.
Until the door of the study.
Then make it into a special buckle shape so that the key can be put into the belt.
Then use the chess pieces in the study room to form a triangle.
Let the excess tape wrap around the pieces that have been placed into a triangle.
Then put a blue book on top of the chess piece.
The key point is the placement of the chess pieces.
The base must be facing up.
If the base is facing down, the pieces will not fall to the ground as the strap is pulled away.
Soon, A Li Yuyue finished all this.
Yuyuki Agasa stood at the door.
He began to close the study room, and then dialed the landline phone in Professor Hirota's study room.
A miracle happened!
Hiroyuki Agasa successfully dialed Professor Hirota's landline.
The belt that Conan pulled out actually began to retract automatically.
The key then passed directly through the crack in the door below, successfully knocking the chess piece down.
The key was pressed under the book.
As for the remaining tapes, they were automatically returned to the tape reel.
At the same time, it also explains why the length of the blank paragraph in the call message is as long as two hours!
After Agasa Yuyuki finished the experiment.
Officer Henggou said directly to Mr. Shirakura: "You have nothing to say now, Mr. Shirakura. If you still want to make excuses, then we can test the damaged straps. Your fingerprints should be on the straps inside."
Mr. Shirakura was questioned like this.
He could only confess the reason for his crime.
Just after Mr. Shirakura was taken away, Haibara Ai said to Conan with tears on her face: "Did you know that Miyano Akemi's pseudonym is Masami Hirota?"
After Conan heard this, he could only say in a comforting tone: "I'm sorry, I really didn't know that your sister was the pseudonym Hirota Masami. And when I got there, your sister had already passed away unfortunately."
Haihara Ai ignored Conan's comfort and looked at the blank magnetic disk in her hand.
Two lines of clear tears suddenly appeared on his face.
Arisuki could only walk to her side, squat down and pat her back gently to express comfort...
