Conan ran out of the room and closed the door.
He spoke loudly so that everyone in the room could hear his explanation.
"The murderer first locked the door outside the doorknob, then put the key on the ground and started making phone calls."
Conan took the mobile phone borrowed from the police officer and dialed the number of the landline in the room.
Soon, the phone in the room rang.
Since no one answered, the phone automatically activated the phone message function.
Conan continued his reasoning after hearing the phone ringing outside the door.
“From this the answering machine will start up and the tape will be rolled into it.
This force allows the key outside the door to pass through the crack below, and then reach under the notebook designed in the center of the house.
After hitting the chess piece, the balance of the chess piece was destroyed, and the key was trapped by the fallen notebook. "
Seeing this, everyone couldn't help but exclaimed and gasped.
"Suppress it!" Morioka couldn't believe it.
Hui Yuan Ai's heart sank even more.
Her words were exposed, and this feeling made her heart tremble, a bit dull, and without reason fear.
Henggou Police Department was also a little surprised, but he still said in a deep voice.
"I see, as long as the answering machine continues to be activated, the tape will be completely rolled up and the evidence will disappear!"
The method is explained.
Conan opened the door and said innocently.
"How's it going? Is it going well?"
Dr. A Li laughed and was a little surprised, "Ah, you were right, Shinichi!"
"!!!"
"Huh?" Henggou Police Department looked at the other party in shock.
Seeing this, Dr. Ali quickly laughed seriously and said: "Ahaha, no... I mean, it's just as I expected! Ahahaha...
At the beginning, if you just put the pressing position of the chess piece in the corner of the notebook, it will be difficult for the chess piece to be pressed under the notebook.
But even if it's pressed down, there doesn't seem to be anything wrong with it. "
Dr. A Li was smiling awkwardly, but Conan had no choice but to disguise his voice again, so he had to suddenly change his face and continue to cooperate, which looked very weird.
However, the Henggou Police Department did not pay attention to this.
He pondered for a few seconds, "So, the only person who can use this technique is to leave 10 messages on the answering machine...
Mr. Bai Cang, the murderer is you, right? "
The Henggou Police Department turned their heads and looked straight at the other party.
Hearing this, Bai Cang's face stiffened and his heart trembled.
Mrs. Hirota glared at him, "Did you kill my husband?!"
"Wait, wait." Bai Cang finally came back to his senses and stammered.
Henggou Police Department frowned and said coldly: "This tape has twists everywhere. This is evidence of your method! You'd better admit it quickly!"
As he spoke, he pressed forward step by step.
Bai Cang was sweating profusely, and said calmly with a stiff face: "Mr. Police, please wait a moment.
Yes, the technique just now was very powerful, but how can you say that I did it?
In fact, the only thing I could do was leave too many messages!
Besides, if I was really the murderer, how could I go all the way back to the scene? "
Conan heard that the other party was still trying to quibble, but he immediately continued to speak in Dr. A Li's voice.
"The reason why you came back here is because you want to recycle something, right?"
Bai Cang: "?!!"
"Yes, it's the one with your fingerprints on it, the tape of the answering machine." Dr. Ali said slowly.
Bai Cang's eyes suddenly shrank, and his whole heart lifted.
“The first thing I noticed when I saw the tape just now was that there were obvious fingerprints on it.
So I decided that this was definitely a crime of unpreparedness and pure impulse!
Maybe you met the bald professor tonight and got into an argument for some reason, so you killed him without thinking. "
"..."
Under Conan's well-founded inference, the Henggou Police Department looked at Bai Cang, who was silent, "Then, can we go to your house and have a look? Mr. Bai Cang."
Bai Cang's face was gloomy, his teeth kept trembling, he was a little unbelievable, but also a little relieved.
After a moment of silence, he finally spoke coldly.
"I parked the car at the door. There was a glove box on the car, and all the magnetic disks were in it, even the magnetic disk with the photo on it."
"That photo?" Henggou Police Department was a little curious.
Bai Cang forced a smile on his lips, "Didn't I just say that? There is a magazine plan to do a report on the theme of the unexpected side of models.
So I asked Professor Hirota to send me photos of me dressed as a woman at the university anniversary.
But I never expected that the package the professor sent me contained a note saying that you are nothing more than that.
And my past face..."
He began to describe his reasons for killing, resisting the urge to kneel down and cry.
Just like that, he was taken away by the police.
The Henggou Police Department smiled widely, "Ah, the reasoning is so wonderful! It's all thanks to you that this case was successfully solved, Dr. Ali."
Hearing this, Dr. Ali touched the top of his bald hair with some embarrassment.
"Ah haha, where are you? Can you please give me the magnetic disk I came here to get?"
The Henggou Police Department was startled, "How is this allowed? All evidence must be taken back to the police station for investigation."
(Kasuga Ling: What do you want to investigate? Sorry, I didn’t leave a single magnetic disk~)
Hearing what the Henggou Police Department said, Dr. Ali turned back to Conan and asked in a low voice: "You heard it, what should you do?"
Conan said helplessly.
"There is no other way, we can only give up today."
Dr. A Li nodded, said goodbye to the Henggou Police Department and was about to leave, but suddenly he caught a glimpse of Hai Yuan Ai's face darkened beside him.
She lowered her head slightly, her brown hair covering up her strange expression, and tears were quietly sliding down her fair cheeks, making people feel pitiful.
She suddenly raised her head, her crystal clear eyes full of mist, looking straight at Conan.
"Why... why didn't you save my sister at that time?"
Conan was startled. He was at a loss and felt inexplicably panicked.
Haibara Ai couldn't bear it any longer and burst into tears, "Haven't you figured it out yet? Masami Hirota is actually named after Professor Hirota!"
Her words were trembling and crying.
Conan's heart trembled, and his expression changed drastically.
"Could it be that the billion-dollar robber Hirota Masami is..."
He couldn't help but recall the woman whose autumn-like eyes were always full of tenderness.
Hui Yuan Ai let go of her voice and cried, "Why?! Since you are so capable of reasoning, you should be able to see through my sister's matter easily!
But...but you...why didn't you..."
She clutched Conan's clothes tightly and cried bitterly, crying at the top of her lungs.
Conan had a complicated look on his face, and his eyes flashed with extreme guilt.
Again.
The pain he had buried in his heart and dared not face came to mind again. Every detail of the tragic scene was extremely clear, as if imprinted deep in his soul.
