The middle-aged man's face was not very good, and he looked nervous holding the box in his hand. He approached Kei Suzuki and said, "Hello, Mr. Officer, I'm Ishikawa, the president of Manten. Actually, three days before this event, I received a strange letter. ”

As he spoke, Ishikawa opened the suitcase he was holding and took out a letter from it. Kei Suzuki took the letter from Ishikawa's hand, opened it, and casually asked, "What kind of strange letter?" ”

But after opening the letter, Kei Suzuki was a little surprised and said, "This is a threatening letter!" Why didn't you notify the Metropolitan Police Department immediately after receiving the letter? ”

Ishikawa sweated profusely and said, "I'm sorry! Actually, at first, I just thought the letter was just scaring me. ”

At this time, other officers of the Forensic Division discovered something else at the scene of the explosion. They are a key and a circular metal logo with a red letter M. Kei Suzuki looked at the deformed metal disc that had been blown up in his hand, and asked the few people in front of him, "What is this, does anyone know?" ”

When Ishikawa saw the letters on the metal disc in Kei Suzuki's hand, he turned the side of the suitcase he was holding in his arms with the company label towards Kei Suzuki and said, "This is our company's badge." ”

Kei Suzuki was stunned when he heard this, and said, "President Ishikawa, may I ask if the person who was killed by the bombing was from your company?" Otherwise, how could there be your company's badge at the scene of the explosion? ”

Ishikawa shook his head and said, "No, no one from our company has been harmed. I don't know where this badge came from, there are 4 people in our company today, my suitcase is here, and I don't know if a few of them are still there. ”

Conan was surprised when he heard this, he saw the box that the man who had been killed in the explosion had taken out from the front desk. But since this man is not from the Mantian Company, why was he able to retrieve this box from the front desk?

Looking at the Mantendo Company badge in his hand, Kei Suzuki put it aside and asked the people in the identification class to check if there were any clues on it. His gaze turned to the people of Mantendo Company, and among the three young people in the development department, Kei Suzuki had already noticed that there were two people whose expressions were not quite right.

Conan, on the other hand, noticed something was wrong when he watched Kei Suzuki hand the company badge of Mantendo to others. That is, the badge in Kei Suzuki's hand is bent in the wrong direction! In Conan's memory, the metal badge has the lettered side facing the outside, and if the bomb is really on the toilet door, then the badge should be bent in the direction of the inside of the box after the badge is impacted.

But what Conan saw was that the side with the letters was bent!

What does this mean?

In Conan's opinion, this suggests that perhaps the location of the bomb explosion was not on the door of the toilet, as the people in the identification class had said. It is very likely that the bomb that exploded here exploded in the suitcase of the deceased, and this incident was a murder case, and the murderer was the one who gave the box to the man in black.

Not to mention the problem that Conan discovered, let's just talk about Kei Suzuki, his face changed greatly when he knew that the person killed by the bomb had collided with him, and Nakajima said wisely: "Mr. Nakajima, do you know the deceased who was killed by the bombing?" ”

Although Nakajima Hideaki's face was a little wrong, he still shook his head and denied: "I'm sorry, officer, I don't know that person." ”

Keichi Suzuki: "Really? ”

It was at this time that Conan suddenly ran out of the toilet. Seeing Conan's actions, Kei Suzuki's heart moved. However, he didn't follow out immediately, but kept asking this Nakajima Hideaki, he knew that Conan should have discovered something he hadn't noticed, but Suzuki Kei felt that the murderer this time was among these people. And maybe it has something to do with this Nakajima Hideaki.

In this year, Suzuki Kei also learned some ways to handle cases, so Suzuki Kei has been asking from Nakajima Hideaki by knocking on the side. It's just that after Nakajima Hideaki found the dead man, although his face was not very good, he insisted that he had nothing to do with the man in black who was killed.

However, although Kei Suzuki did not get any useful clues from Nakajima Hideaki, he found that the relationship between Nakajima's colleagues Ueda Koji, Takeshita Hironobu and their president Ishikawa was a bit complicated. Although the three of them showed more respect for the president, Ishikawa, Kei Suzuki still saw the existence of resentment in their eyes.

And Conan also inquired about it from the locker the day before yesterday, and no one has taken anything from here until now. Then he thought that the man in black seemed to have taken the number 98 number plate from Miss the day before yesterday. However, Conan remembers that when he deposited his belongings, Kogoro Mori was number 96 and Ran was number 100.

And the three employees of Manten, Hideaki Nakajima, Koji Ueda, and Hironobu Takeshita, they were the ones who cut into the queue to receive the number plate after Mori Kogoro received it. So the number plate of the three of them should be 97, 98, 99, but the person who was killed just now has taken the number plate of 98 away, which means that there must be something in the middle.

Then Conan wanted to see which of the three people had his number plate replaced. As long as you know which person's number plate has been changed, then you will know who the murderer is.

Thinking of this, Conan ran back to the toilet and wanted to ask these people about it. But what Conan didn't expect was that when he came to the toilet, he was stopped outside by a police officer and didn't let him in.

Fortunately, Kei Suzuki has been paying attention to Conan's actions since he found out that he was running out, and when he saw that Conan was about to come back and was stopped, he ordered the police officer who blocked him to let Conan in.

When Conan came back to the scene again, Kei Suzuki pulled Conan aside and said, "How is it, Conan, have you found anything?" ”

Conan looked at the three men and said, "The murderer may be one of them!" ”

Kei Suzuki nodded, not at all strange and said, "What do you say?" ”

For Kei Suzuki was surprised by himself at all, Conan didn't doubt it. He told Kei Suzuki what he was thinking just now and said, "Now we only need to look at who has changed the suitcase in the hands of the three people to know who is the murderer." ”

After Kei Suzuki heard Conan's words, he also thought about it. He agrees with Conan's words, this murderer should be one of the three, but he wants to be convicted with a number plate, and it's really a bit of a thing. Anyway, it's a clue and it's worth a try.
