The famous criminal in the world of Conan

"Inspector Yokomizo, arrest him first. He is the murderer."

Bai Masong said to Henggou while he was comprehending.

"What? Is he the murderer?"

Yokogo Chanwu was shocked, but because of his trust in Baimasong, he still took action directly and subdued Baicangyang.

"Officers, officers! Is there some misunderstanding here?"

Bai Cangyang was panicked, but still pretended to be innocent and shouted.

"Inspector Hakuba, is he really the murderer?"

Henggou Chanwu asked Baimasong.

After all, he has been a policeman for so many years. He has seen prisoners running away and prisoners staying at the scene, but he has never seen a prisoner who ran away and then came back.

"Ah."

Bai Masong nodded and continued,

"I'll tell you the tricks of the secret room, and you'll understand."

"You, you even know the secret room technique?"

Henggou Chanwu looked at Baimasong with admiration.

I have to say that Inspector Yokomizo, like Inspector Megure, is a very good supporting actor.

Bai Masong did not continue what Henggou Chanwu said, but asked the police officer next to him,

"Can you get me a tape that's the same as the one used live?"

The police officer was still a little hesitant, but Yokogo Sango immediately waved his hand.

"Why don't you go get it for Inspector Hakuba!?"

"Yes!"

Not long after, the tape was returned.

Bai Masong took the cassette, first pulled out a certain length of the tape, and then put the cassette back into the phone.

Bai Ma Song explained while doing it.

"We first pull the tape of the cassette to the appropriate length, then put the cassette back into the landline, but leave the tape outside."

"Then, we walk out of the door again, leaving enough length to pass the key through the belt, fold it back into the door, and put the belt on the chess set, and the secret room trick is complete."

Bai Masong spoke as he worked, and soon completed the arrangement.

After finishing, Bai Masong reminded again,

"This technique is very simple, but there are three points to note."

"The first is that the strap outside the door needs to be long enough, long enough so that the key can reach the keyhole without pulling the chess set."

"Second, the chess set, the book, the key outside the door, and the phone. The four points must be basically connected in a straight line, otherwise they will be in the wrong position."

"The third thing is that the chess set must be placed upside down because its base is very stable. If it is placed upright, the key and the chess set will be pulled back by the belt."

“Only by placing it upside down can the chess set collapse and the key be pressed under the book.”

Bai Masong was like a teacher, explaining an analytic geometry problem to the students in the audience.

Almost all the students listened very carefully, and Yokomizo Sango even took out his police notes to take notes.

At this moment, Haibara Ai also had an inexplicable sense of pride, that kind of feeling that that person was so great, but, he was my brother.

Especially, seeing the nationally renowned detective, Conan, still listening attentively, Haibara Ai's feelings became even stronger.

"Brother, do you always solve cases so quickly?"

Ai Haibara pretended to be indifferent and asked Conan beside her.

"yes,"

Conan sighed with a sad face.

"As long as Brother Song is around, I have never been able to see the truth before him."

Some are happy and some are sad. Compared to Conan and others, Shirakura Yang's mentality gradually collapsed.

He now just felt weak all over. Originally he was captured by Henggou Chanwu, but now he wanted to hang on Henggou Chanwu's body.

"Next, we just need to keep making phone calls and ask the recorder to recycle the tapes."

Bai Masong concluded.

He walked outside the door, took out his cell phone, and dialed the landline in the study.

Things turned out just as he expected. The tape was constantly being recycled by the recorder, and the tape drove the key along with it, hitting the chess set. The chess set collapsed, and the book fell down with it, crushing the key. Finally, the tape was recycled by the recorder.

"I see. To complete this locked room technique, you must keep making phone calls. So Mr. Shirakura, who made ten calls in a row, is the murderer!"

Yokoguro Chanwu finally understood everything and said.

"Yes."

Bai Masong nodded and continued,

"As for the evidence, it's in the tape."

"I think Mr. Shirakura came back because he wanted to retrieve the tape with fingerprints on it."

Seeing that Bai Masong had told him what the evidence was, Bai Cangyang also lowered his head and pleaded guilty.

The reason was that he wanted to take a photo, but Professor Hirota took out a photo of him before plastic surgery and said he would send it to their unit.

This made Shirakura Yo think that Professor Hirota was going to frame him, so he lost control of his emotions and killed him.

In fact, Professor Hirota's original intention was to make him face himself and not feel inferior because of his past appearance.

Of course, these are all for later.

Bai Masong and others took the disk containing the drug information and left.

.................................................. .................................................. ......................

Soon, the four returned to Dr. Agasa's home.

Looking at the blank screen in the computer in front of her, Huibara Ai sighed slightly.

"Can't you?"

Conan hurried over and asked.

"No, it's been emptied."

Huihara Ai said lightly.

"Was it the vodka?"

Conan asked again,

He asked this because he could tell that the insurance salesman in the tape recorder was Vodka.

Conan could tell that Hakubamatsu and Huihara Ai were naturally more capable, so none of the three said much.

"no,"

Huiyuan Ai shook her head.

"It should be caused by a virus that locked the internal data of the organization."

"Alas! It seems that I have to do something else from now on!"

Conan sighed and said regretfully.

"Don't do it any other way!"

Bai Masong looked at the two of them and said coldly,

Now that everyone has laid their cards on the table, let's just be frank.

"Don't interfere in the organization's affairs unless it is absolutely necessary!"

"Especially you, Conan, don't just jump on the organization once you smell it."

"The strength of the organization is definitely beyond your imagination!"

"There is only one thing you need to do now, and that is to hide yourself!"
