On the vault floor of the Rice Flower City Bank, hearing Maori Kogoro say this, Gao Yuan was a little curious.

"Who is Mayuko-san?"

After all, when he first entered the vice president's office, Kogoro Mori said that Mayuko had called him. And now the person who is suspected of being Mayuko is lying in the vault and not knowing whether he is alive or dead, which is really strange.

"She's a teacher at Xiaolan's computer training school, and she's also my drinking friend, and she doesn't know anything else."

Kogoro said.

"The Computer Training School is an affiliate of our group."

Takeo Emoto chimed in, "She also doubles as a teacher there. ”

As he spoke, Kogoro on the side dialed Mayuko's number with his mobile phone, and sure enough, the mobile phone in the vault rang - "Sure enough, it's Mayuko!" ”

Kogoro leaned on the door and shouted, "Miss Mayuko! Cheer up! ”

Seeing this, Takeo Emoto also went up and shouted.

Gao Yuan ignored them, and instead looked at the piece of paper on the wall with the words of warning written on it—that is, someone had changed the password to the vault and left such a piece of paper. The bank didn't dare to call the police, so it called for a Maori detective to come over, only to find that there were people lying in the vault that could not be opened!

"Speaking of which, why did you come to Mr. Maori?"

Takato asked. Now that Maori Kogoro is not famous, it is a little strange that such a serious case from the bank would find him.

"Oh, it's the Maori detective that Miss Mayuko contacted."

Takeo Emoto said, Takato then looked at Kogoro, who was stunned for a moment and explained.

"It's noon today. At that time, I received a call from Mayuko, thinking that I was calling for some kind of social event, but Mayuko told me very seriously on the phone that she was now experiencing a very difficult matter and wanted to discuss it with me, and said that she must not tell the police and asked me to come to the bank to find her. ”

As he spoke, Kogoro walked over to the paper on the wall, "Now it seems that the things that can't be said refer to this matter." ”

After listening, Gao Yuan pondered for a moment.

"In other words, after discovering that the vault password was changed, is Miss Mayuko outside the vault?"

"Yes."

Takeo Emoto said, "It was also after consulting with her that she went and invited a Maori detective to come over." ”

Gao Yuan took a closer look at the iron door structure of the vault and the keypad of the combination lock, and asked, "This door is a computer-controlled automatic door, right?" ”

"Yes."

Takeo Emoto said.

"Then the only people who can change the password should be the bank's insiders."

After all, Gao Yuan said, this kind of facility cannot be connected to the Internet.

"Who can enter the vault?"

"In addition to us, two security guards, and three others."

Takeo Emoto said, so Takato and Kogoro asked Takeo Emoto to call these people.

Soon, five people arrived, in addition to the two security guards, the other three were: general manager Yuzo Nimura, the head of the vault Yoko Sakai, and the head of the corporate sales department Ryosuke Hasegawa.

Kogoro looked at the five people with fierce eyes, then turned his back and said solemnly: "Prisoner, what the hell is ......?"

Before he finished speaking, Takato saw a dumbfounded scene: Nimura Yuzo, Jingyoko, and Hasegawa Ryosuke actually raised their hands at the same time!

Seeing Gao Yuan's surprised expression, Xiao Goro turned his head and looked at the three people who raised their hands, and his face was also shocked: "You three, it won't be a gang!" ”

"It's not!"

The three of them spoke in unison, and then Nimura Yuzo stepped forward and said, "I did it alone." ”

"No, I did it!"

Jing Yoko retorted.

"That's not right! I'm the prisoner! ”

Ryosuke Hasegawa also stepped forward and said.

"You guys, recruit from the truth!"

Kogoro, who was stunned by the confessional attitude of the three of them, yelled.

"I've made a big mistake, even though I didn't intend to kill her!"

Nimura said, and was pushed away by Yoko Sato.

"I caused her death, and I was the one who killed her!"

Seeing this, Ryosuke Hasegawa immediately grabbed Yoko Sakai, "Why do you want to lie like this." ”

"You're the one who lied."

Jing Yoko asked rhetorically, "It was indeed me who killed her." ”

Looking at this situation, Gao Yuan couldn't help but want to laugh: It's interesting, now the life and death of the people in it are still unknown, but at the same time they admit to killing people, and no one says anything about changing the password.

"It's too late."

Jing Yoko said, walking to the password press keypad, "If you want to open this automatic door and alarm the police, the bank will explode, and the matter will really be irreparable!" ”

Seeing this, Gao Yuan smiled, pointed to the piece of paper, and asked, "Then, who is the person who posted this?" ”

As a result, all three shook their heads at the same time.

"Huh? Ay! Ay! ”

Kogoro was surprised: "Why didn't everyone admit it this time?" ”

"In that case, let's ask separately first."

Takato said, asking Takeo Emoto to prepare three empty rooms.

Gao Yuan first questioned Nimura Yuzo, but before Gao Yuan could ask much, he first confessed a piece of information.

"Actually, I have an ulterior relationship with Mayuko Sonoda."

"Cheating?"

Gao Yuan asked tentatively.

"In the beginning, we made a covenant with each other and didn't tie each other down. But recently, Mayuko said that she couldn't take it anymore. She forced me to divorce or else she would tell my wife everything. At that time, I was dizzy, and when I came to my senses, I found that I had strangled Mayuko to death. ”

Nimura held his forehead and said with some remorse, "I know this will happen one day, but if I don't do this, my family will be ruined!" ”

But Gao Yuan frowned, "Where did you kill her?" ”

"It's in the vault, at that desk."

Yuzo Nimura said.

"What's the deal with the vault door? Didn't lock it at the time? ”

Takato asked, and Nimura nodded.

Seeing this, Takato realized that he had thought of a wrong question, and hurriedly asked Takeo Emoto, only to find out that when he found that the password was changed, the door was actually open, but when Kogoro arrived with Takato, he saw that the door was locked, and it was an automatic door, and the lock door only needed program control.

On the other side, Kogoro was asking Jing Yoko, and Jing Yoko blurted out directly: "That woman, there are some bad rumors." ”

In this regard, Kogoro was very surprised, and immediately asked, "Mayuko has bad rumors?" ”

Seeing Kogoro's attitude, Jing Yangzi smiled coldly.

"Embezzlement of public funds! She took advantage of her work to embezzle public funds and take out the valuables kept in the safe without authorization, using them as collateral to raise funds for foreign exchange speculation, and then put the items back after the delivery date, so that the money earned would belong to herself. ”

As he spoke, Jing Yangzi suddenly burst out and looked very angry.

"What a joke! How can there be such a cheap thing, because this little girl wants to bury my hard-earned career, so before the situation becomes serious, I have to let her turn herself in! ”

Viciously, Jingyoko said to Kogoro.

"Even if you put the blame on someone else, you might also be fired for it, right?"

Kogoro was not intimidated by the other party's momentum, "So you want to cover it all up, it seems unlikely, right?" ”

"I expected her to come today to return the misappropriated items, so I stopped her in the vault. As a result, I had an argument with her, and by the time I came to my senses, I had strangled her to death. ”

Jing Yoko said.

"Did you put the paper on it?"

Kogoro asked.

"No, but I don't think it's necessarily a trick."

"She's an excellent system engineer, and it's a piece of cake to hack into such a system." Besides, we don't know what she's putting in the safe, so if we check it, we might find a bomb or something! ”

"That? Is it really Yuko's post? ”

Kogoro muttered to himself.
