Sunday, March 30, morning, Manheaven Branch.

After waiting for a while, Ueda Koji was brought over by a police officer. He saw the bodies of Hideaki Nakajima and Hironobu Takeshita and immediately exclaimed.

Section Chief Matsumoto asked, "Mr. Koji Ueda, what is your number plate?"

"It's Ninety-Seven. Ueda Koji said as he took out the number plate.

Matsumoto asked the head of the division to go to the counter in the side hall with a number plate and take out the corresponding briefcase.,After checking it, it was found that it was some development materials about the game.。 President Ishikawa took a look at it and thought there was no problem.

"Mr. Ueda, what kind of relationship do you have with Mr. Nakajima and Mr. Takeshita?" asked Section Chief Matsumoto.

Koji Ueda said, "All three of us came from the same university boxing club, and after graduating, we were fortunate enough to join the development department of the Tokyo branch of Mantendo Company. ”

"So, you know them well?" asked Matsumoto.

Ueda Koji said, "Well, maybe. ”

"And what is the relationship between the two of them?" asked Matsumoto, "Do you think Mr. Takeshita had a motive to kill Mr. Nakajima?"

"This ......" Ueda hesitated.

Matsumoto said, "That is, there is." ”

"Takeshita has been dating a girlfriend since junior high school, she entered our university with Takeshita, became the manager of a boxing club, and then she dated Nakajima, and then she was dumped by Nakajima, and then she committed suicide. "If I'm not mistaken, today is her death day." Then he added, "Also, Officer, I don't know what to say, Takeshita didn't go to see her that day because she was working overtime, maybe ......."

Section Chief Matsumoto asked, "You mean, you think that this explosive was planted by Mr. Hironobu Takeshita, in order to take revenge on the Mantendo Company?"

"What?" exclaimed President Ishikawa in surprise, "just for this to blow up my company?"

"This ......," Ueda Koji didn't know how to answer for a while.

After asking about the woman's situation, Matsumoto sent someone to verify.

"Hey, uncle," Conan whispered to Maori as he broke free from Ran's embrace, "I heard someone in the bathroom in the hallway outside the bathroom, 'Why can't you plug it in?' ’”

"What?" said Maori, "why didn't you say it earlier." ”

Matsumoto asked, "Mori, what's the matter?"

"Yes, Administrator. Maori repeated what Conan had just said.

After reading it again, Matsumoto asked, "Kid, you're Conan, aren't you? Are you sure it's that person's voice?"

Conan said, "Yes, he should have been the only one in the bathroom at the time. ”

Matsumoto asked, "Mori, how do you understand this?"

"Me?" Mori was stunned for a moment, then heard Yamazaki whisper "key" behind him, and immediately said, "Administrator, I think it means that the key can't be inserted into the keyhole, and then I found that the briefcase is not closed," and then heard Yamazaki say "lock", and immediately changed his words and said, "Lock, if the briefcase is not closed, the waiter at the counter will remind you." And when he opened the briefcase, he set off the explosives inside the briefcase, and an explosion occurred. ”

President Ishikawa exclaimed in surprise: "This guy is crazy, isn't he afraid that someone will accidentally open the briefcase and let the explosives explode next to him?"

yes, it's dangerous today. Yamazaki thought to himself, because of all the coincidences, Mr. Hironobu Takeshita has been one step away from me, and for this kind of trigger-type explosive, I can only feel the danger if there is an action that causes it to explode, and the center of the explosion can cover my location. Alas, this is really, but it is also true, otherwise there is no need to go out, after all, the fuel tank of a car can be counted as a trigger type explosive.

"Hey, uncle," Conan asked the forensic officer, "how did you open these briefcases?"

The forensic officer said, "Neither of these briefcases is locked. ”

"Hmm, it's not locked," Matsumoto asked, "So, let's see if the key is right?"

The forensic officer tried, "Mr. Takeshita's briefcase for locker 99 doesn't match the key in his hand. ”

"The key in Mr. Takeshita's hand does not match the briefcase in his hand, and the key in the hand of the man in black does not match the briefcase in his hand, and the briefcase of the man in black is interchangeable with Mr. Nakajima's briefcase. Sonoko smiled, "Ah, I see, Mr. Takeshita must have secretly swapped his number 98 plate with Mr. Nakajima's number 99, and at some point after that, Mr. Nakajima exchanged number plates with the man in black......"

Conan said, "Ah, I bumped into the man in black when I went to the bathroom with Mr. Hideaki Nakajima. ”

"Smack!" Mori punched a large mushroom on Conan's head, "Boy, how much more do you have to say." ”

"Dad, how can you do this. Lan said.

"That's right. Ayumi said angrily, and then asked Conan, "Does it hurt?"

Mitsuhiko said, "It shouldn't hurt. ”

"Yes. "Conan didn't cry. ”

Conan, who was covering his head, straightened up his triangular eyes, crying and pain, must it be related?

Matsumoto said, "Okay, Mori, you can't blame him for that. ”

Sonoko glared fiercely at Conan, who interrupted her reasoning, and continued, "Then the man in black took the number plate 98 and took out the briefcase containing explosives that Mr. Takeshita had prepared for Mr. Nakajima. The man in black had come to trade with Mr. Nakajima, so he went to the bathroom to confirm the contents of the briefcase, and he used the key that Mr. Nakajima gave him to correspond to Mr. Nakajima's briefcase that Mr. Nakajima had put in No. 98, which of course did not match the briefcase that Mr. Takeshita had put in the No. 99 locker, so he said, 'Why can't I get in?'. Then he noticed that the briefcase was not locked, and then he said, 'Huh, it didn't close.' Then he opened the briefcase and caused an explosion. In other words, Mr. Takeshita killed the man in black by mistake very coincidentally, and then killed Mr. Nakajima before committing suicide when he found out that he was still alive. And Mr. Takeshita will carry a briefcase that may accidentally explode at any time because he has already decided to die. ”

Lan asked, "But why did he kill himself?"

"Under our law, the intentional placement of explosives in a public place and causing death is a very serious crime, and the death penalty is very likely. Yamazaki said.

"I see. Lan said, "Garden, you are so powerful." ”

"Of course, I'm a detective. Yuan laughed.

What kind of reasoning is this, it's just a summary, Conan asked, "Sister Sonoko, Mr. Nakajima will take the briefcase because he thinks there will be money in it, so why did Mr. Takeshita take the briefcase?"

"Ah, this ......" Sonoko thought for a moment and said, "Mr. Takeshita didn't know about Mr. Nakajima's deal with the man in black, and there was an explosion, of course I went to confirm it, uh......"

Matsumoto said, "Indeed, at that time, there should have been no briefcase in the No. 98 memory locker. ”

"I see," Mori said, "When Mr. Takeshita went to check, he found that locker No. 98 was empty, so he took out the briefcase in locker No. 99, and then found that the briefcase was unlocked, and then found out that it was a trade secret, so he became ill-willed, and then after discovering Mr. Nakajima, hatred came up again, and finally it became like this." Mr. Nakajima's No. 124 briefcase is not locked, so he should have confirmed the money inside. ”

Conan asked, "But since Mr. Nakajima's briefcase in Locker 98 is not locked, why does the Man in Black still use the key?"

"Of course, it wasn't agreed. Maori said, "When you and Mr. Nakajima bumped into the man in black, they didn't speak, right? Anyway, if you can open it, there is no need to say that there is no lock, and the key may be a backup key that has been traded for a long time." Then he asked the forensic officer, "I just saw that you took out two briefcase keys from Mr. Nakajima, can you try the other one?"

The forensic staff tried it, and Mr. Nakajima's other key was indeed able to hit the briefcase next to Mr. Takeshita.

"Very well," said Section Chief Matsumoto, "if the key in the hand of the deceased in the bathroom was able to open the briefcase that Mr. Takeshita had taken out of locker No. 99, then this incident is the same as Miss Suzuki's reasoning." ”

While waiting, Conan pulled Yamazaki aside and whispered, "I didn't say something earlier, that guy's name is agave, and I heard him mention gin." And vodka, he must be the strong man next to Gin. ”

"Gin?" Yamazaki asked with a smile, "It can't be such a coincidence, right?"

Conan hurriedly said, "It's true." Then he repeated what Tequila had said on the phone, "They must have bought those materials." ”

"It's a little too early to tell. Yamazaki said, "That briefcase might have something else in it." ”

"I went in and looked at it, but I didn't find any scraps of paper. "That briefcase should be just a bomb." ”

"You've been there?" Yamazaki laughed, "Then you can make up a reason." ”

"Uh......" Conan was stunned, and then sweated.

Yamazaki asked, "You won't touch anything again, will you?"

Conan said with a bitter face, "When I retrieved the transmitter, ......" said and made a gesture of taking it.

"It's okay, if you know it's a child's fingerprints, you won't check them. Yamazaki said, "But you must be careful in the future and take care of your fingerprints, otherwise you will be in big trouble." Then he said, "Forget it, you can't remember what you said." ”

At this time, forensic personnel came to report that the scene of the explosion had been dealt with. ……
