The famous criminal in the world of Conan

Henggou Chanwu's action of asking the question as soon as they met caught Baimasong and others off guard.

Bai Masong did not answer directly, but asked back,

"Inspector Yokomizo, what do you think?"

After hearing this, Henggou Chanwu glanced around the scene and said with some hesitation,

"It should be an accident, right?"

Accident?

After hearing what Yokomizo Chango said, Conan and Haibara Ai couldn't help but twitch their lips.

The level of Inspector Yokomizo is indeed worthy of the phrase "if you don't understand, just ask."

Seeing that Bai Masong did not oppose him immediately, Henggou Chanwu seemed to be encouraged and continued,

"Inspector Hakuba, look, the windows and door of this study are all locked, and the only key is pressed under the book, so Professor Hirota Masami could only have committed suicide."

Yokoguro Sango pointed at the doors and windows, and then at the key pressed under the book.

Bai Masong nodded first, then shook his head and said,

"Although the doors and windows were locked and the key was in the room, it was still possible that this was arranged by someone."

After Bai Masong finished speaking, without waiting for Henggou Chanwu to refute, he walked to a place and pointed with his finger, indicating for everyone to see.

"Inspector Yokomizo, look at this. Do you think it's weird?"

Where Bai Masong's finger was, there was a telephone. The base unit was placed very neatly, and the microphone was also neatly placed on the base unit, pressed down by a book.

"this one?"

Yokogo Sango looked at the phone that was pressed by the book with a confused look on his face.

He couldn't see what was wrong with the phone, but he still said,

"Um, the books on this landline were messed up when the bookshelf fell down......................."

"wrong!"

Bai Masong interrupted directly.

He is now like a strict teacher, looking at Henggou in contemplation in front of him, feeling that the person is a rotten tree that cannot be carved.

The level of understanding of Yokomizo Chango is comparable to that of Sato Miwako.

Bai Ma Song directly revealed the answer,

"Since the book fell down, why is the microphone on the landline still there intact?"

"Yes ha!"

Henggou suddenly realized the truth.

"I see. So the murderer deliberately messed up the room and made it look like an accident in an attempt to get away with it!"

Yes, if it weren’t for Brother Song, the murderer would have succeeded.

Conan and Haibara Ai thought.

Bai Ma Song also nodded.

"Okay, then, this is a closed-room murder case."

Yokogouch came to a conclusion after some meditation.

Then, he asked Hirota Toshiko,

"Mrs. Hirota, may I ask if anyone has come to see Professor Hirota tonight?"

“Well…”

Hirota Toshiko said hesitantly,

"Because I'm going to a party with the lady next door tonight, so I won't be home all night."

"So what time did you go out and what time did you come back?"

Yokoguro Chanwu continued to ask.

"I left home at eight and came back at eleven."

Hirota Toshiko replied.

"So, ma'am, you didn't see the visitor?"

Yokoguro said.

"No,"

Hirota Toshiko denied it, she recalled and said,

"Actually, when I went out today, I saw the first visitor who came. I remember his last name seemed to be Hosoya."

Yokoguro Chanwu nodded and said enthusiastically,

"very good!"

Then, he instructed the police officer next to him,

"Go and bring back the man called Xiya who was here today."

"Yes."

The police officer replied.

After the police officer left, Yokomizo Sango asked Hirota Toshiko,

"Besides that, do you remember any other guests who came to your house?"

"This? I really don't remember."

Hirota Toshiko shook her head.

"That's it,"

Henggou Canwu said with some regret,

"In that case, we can only look for Professor Hirota's students and ask them one by one."

At this time, Bai Masong pointed at the phone on the ground and said,

"No need to bother."

Yokoguro Sango turned around with a look of surprise.

"Inspector Baima, did you find anything?"

Bai Masong pointed at the ground and asked Henggou Chanwu to look at the flashing lights on the plane.

"This phone has a voicemail function. You can check the messages on it first."

"Yup!"

Henggou Chanwu pounded his palm hard, and then his face looked as if he had suddenly realized something.

Having said that, he immediately took action, bent down, and checked the phone message.

I don’t know, I’m scared.

Henggou Chanwu said with some surprise,

"There are thirteen messages in this phone."

Thirteen links?

Bai Masong frowned slightly when he heard the number.

Yokomizo Sango then pressed the play button to play the thirteen messages one by one.

The first one was from Baicang, the second one was from Shenggang, and then the next one was from Baicang again..............................

I listened to the thirteen messages one by one, and found that ten of them were from Baicang, two were from Shenggang, and the remaining one was from an insurance salesperson.

After hearing this, Baimasong began to think continuously.

There are ten messages from Shirakura, there must be something wrong!

Multiple messages, books and chess pieces scattered on the floor, keys pressed under books, a gap under the door big enough to put a fishing line, and the tape seemed to have a lot of empty parts. These.................................

Bai Masong already understood, he knew the method of this secret room.

While Bai Masong was thinking, Yokomizo Sango continued to ask Hirota Toshiko,

"Mrs. Hirota, who are these Shirakura and Morioka?"

"I have met Mr. Shirakura before. He should be my husband's student. He is still very young and looks very handsome..."

"I have also met Mr. Sheng Gang. He is also my husband's student. However, he is one of my husband's earliest students. He often comes to our house and plays chess with my husband............................"

Hirota Toshiko introduced the two people one by one, but she had only seen them before and didn't know their names.

According to her words, Yokomizo Sango took out the police manual and took notes. Just when he was about to ask someone to look for someone else, another person came in from outside the door.

"Um, hello, I'm Bai Cangyang, what can I do for you?"

"It's like this, Mr. Shirakura.............."

When Yokomizo Sango saw that Shirakura had come by himself, he wanted to explain the situation to Shirakura Yo.

At this time, Bai Masong spoke directly.

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