Thinking of this, Gao Yuan immediately walked to the combination lock and prepared to enter the password.

"Hey! What are you doing? It's going to explode! Dangerous! ”

Seeing Takato's movements, Kogoro hurriedly shouted.

"Don't worry, it won't explode."

Gao Yuan said calmly.

The warning statement on the paper did not say that the door would explode when the door was opened, but only that the police would not be called. And the impression that the door will explode is said after Jing Yangzi came over.

Without hesitation, Takato entered the password, and then the door to the vault opened, and the explosion did not happen.

Seeing this, Kogoro immediately rushed in, came to Mayuko Sonoda, and called her name, but after touching her body, Kogoro was suddenly startled and tentatively touched her carotid artery.

"Dead!"

Kogoro retracted his hand, then thought about it again, flipped the collar around her neck, and said in shock, "She wasn't strangled to death!" ”

Gao Yuan also walked in, walked around behind the desk, and saw this young woman in professional clothes, lying on the ground with a peaceful face at the moment.

With a helpless sigh, he walked over to the corpse, crouched down, and took a closer look at the legs that could have been seen outside the vault.

No accident, Takato saw what he expected - a red dot similar to a pinhole.

"Sure enough."

Gao Yuan said regretfully.

Now the question is, who is the murderer?

Getting up, Gao Yuan thought for a while, took out his mobile phone, and sent a message to the email number left on the document.

Soon, the cell phone rang in this vault.

Seeing this, Kogoro immediately picked up Mayuko Sonoda's phone, but found that it was not the sound of the phone.

"In other words, there's another phone here!"

Seeing this, Takato said with some surprise, and then began to listen carefully to the source of the ringtone, and Kogoro also began to find the source of the sound.

Soon, the two noticed that the sound was coming from the row of safes on the wall!

However, with so many safes, how can you determine which one it is!

Kogoro put his ear to the row of safes and began to listen carefully, then narrowed it down to a small area.

Looking at the number of the safe door in this area, Gao Yuan suddenly noticed that there was a number here that was actually "0924"!

Mailbox tail number, vault password, and vault number!

How can it be such a coincidence!

Thinking about it, Takato immediately walked to Mayuko Sonoda's corpse, and began to touch the pocket of her clothes with some apologies, and sure enough, he found a key!

So, Gao Yuan took the key and began to open the safe numbered "0924", and it turned out to be really opened!

Take out the contents and it is a mobile phone, and a diary.

After Gao Yuan briefly checked the almost brand new phone, he began to look through the diary.

After reading the above account, Gao Yuan sighed - all doubts were solved! It's a sad story!

Takato asked Kogoro to go and call everyone over.

When Takeo Emoto led the three of them to the door of the vault, they were all a little surprised when they saw the door of the vault that had been opened, and Takato began to answer.

"I've got the whole thing!"

Gao Yuan said, "I'll explain it in turn!" ”

As he spoke, he walked over to the piece of paper with the words of warning written on it.

"The person who posted this fake explosion notice did it on the premise that Mayuko Sonoda faked her death. The aim is to delay the time when the vault is opened. However, Mayuko-sama is really dead now. In other words, the person who killed Miss Mayuko is not the same person as the person who posted the notice! ”

"What! Mayuko Sonoda her! ”

Ryosuke Hasegawa was surprised, while Yuzo Hitomura and Yoko Sakaiko were also surprised.

"Let's start from the beginning."

Takato said, "It is true that someone in the bank is embezzling valuables from the vault, but that person is not Miss Mayuko, but Mr. Nimura and Ms. Satsu! Of course, you are the ones who appropriated the Ambassador Emerald Necklace! And all the evidence is recorded in Miss Mayuko's diary. ”

As he spoke, Takato handed over the diary to Takeo Emoto, and seeing this, Yuzo Hitomura and Yoko Sakaiko looked ugly.

Takeo Emoto briefly flipped through a few pages, then looked at the two of them with a surprised face, and pointed at them in shock: "You two! ”

"Actually, as long as you read the whole diary, everything will be clear!"

Takato continued, "Miss Mayuko, she is a person sent by the head office to conduct a secret investigation into whether your bank employees have violated laws and regulations. She discovered the actions of both of you during her investigation and recorded the evidence in this diary. ”

Taking back the diary from Takeo Emoto and walking in front of the two, Takato continued: "But just as she was about to hand over the collected evidence to the head office, an accident happened. That's you appropriating the ambassador's emerald necklace! If the ambassador finds out that your bank is engaged in this kind of behavior, not only will the entire bank be ruined, but it will also have an international impact!

"So, in order to prevent the ambassador from having a chance to open the safe door before returning home, you went to Miss Mayuko, confessed the whole thing, and tried to get her help to get the help of the matter and get the matter to be obscured. So, for the sake of the entire bank, Miss Mayuko compromised. That's why you changed your vault password, faked your death, and posted fake explosion notifications! ”

"That's why you two dare to admit that you killed Miss Mayuko, because you know that Miss Mayuko in the vault is actually fake death!"

Kogoro said at this time.

"How can you two do that!"

Takeo Emoto said angrily.

"Not really!"

Seeing that the matter was revealed, Jing Yangzi still retorted loudly, "We didn't do it voluntarily! ”

"It's President Iwaki!"

Nimura Yuzo also immediately said, "We were only at the behest of President Iwaki that we embezzled the contents of the vault!" ”

"President Iwaki!"

Hearing this name, Gao Yuan suddenly stepped forward and asked, "It was reported missing before, President Iwagi, the person in charge of your bank!" ”

"That's right, everything was instructed by him!"

Jing Yangzi also said, "Most of the money I earned by embezzling valuables went into his pocket!" ”

"And we have no choice but to embezzle the Ambassador's gems!"

"After President Iwaki disappeared, we found out that before his disappearance, he had illegally transferred 200 million yen in cash from the bank's books. If this matter is exposed and the head office investigates, what we did before will definitely be discovered, so in order to make up the money on the books as soon as possible, we have no choice but to embezzle the gem worth 260 million! ”

"That's right, it's over, and we have nothing more to hide! But, but we really didn't kill Mayuko-san! ”

Jing Yangzi said nervously.

"I'm not done yet. Besides, I didn't say you were the murderer. ”

Takato said, pleasantly surprised to get the information about "President Iwaki".
