"So, now all the Heavenly Employees present have retrieved their briefcases from the locker, but how can we determine who is the murderer?"

Under the coordination of the president of Manten, several Mantendo employees present were soon called together, and according to Officer Twilight's instructions, they all took their number plates and took their briefcases back.

However, looking at the current situation, Officer Twilight still couldn't understand it, turned his head to look at Mori Kogoro, and couldn't help but ask with a puzzled face.

"Officer Twilight, didn't you notice?"

Quietly leaned out his face from behind the pillar, looked at the briefcases carried by the several Heavenly Employees present, and when he noticed the style of the briefcase in the hands of one of them, the corners of his mouth couldn't help but show a smile, and then he turned to the bow voice changer and continued to say in Kogoro's voice:

"The briefcases used by the employees of Mantian Company are all uniformly equipped by the company and have the company's trademark briefcases. But now, someone doesn't have that logo on their briefcase......"

Speaking of this, Conan couldn't help but pause, and then said in an extremely serious tone:

"Mr. Nakajima, the briefcase you've been holding carefully since just now, can you explain why there is no Mantendo logo on it now? At the beginning of the deposit, we can see that there is obviously a trademark on it! ”

Hearing this, Nakajima Hideaki's expression changed greatly, revealing a panicked look, but subconsciously still wanted to protect his briefcase, and his body couldn't help but take half a step back-

"Nakajima! Could it be you......"

Seeing Nakajima's reaction, President Mantendo on the side couldn't help but ask with a shocked expression.

"No, it's not me ......"

Hurriedly waving his hand, Nakajima denied in a little panic:

"I'm not the one who planted the bomb."

"Then let me check the briefcase!"

Seeing this, Officer Twilight naturally saw that something was wrong, and then stepped forward and said with a serious face.

"No way!"

Subconsciously, Nakajima held the briefcase in his arms and vetoed it categorically, but looking at Officer Twilight's expression, he couldn't help but panic and wanted to explain-

"This ......"

"What does it matter? Why don't you show it to the officer? There won't be anything important anyway. ”

Ueda, who was on the side, looked at Nakajima's twisted appearance and couldn't help but say.

"However, if there is a plan for a new game in it, I will take it out like this......"

Takeshita wanted to explain at this time, and then Nakajima immediately followed the topic:

"yes, that's how you can't let others ......"

Nakajima tried his best to explain, but Ueda tried to snatch the briefcase and shouted:

"Idiot! You want to be a suspect! ”

But Nakajima still tried his best to hold the box and didn't want to let go-

"You let it go!"

Seeing this, Takeshita looked at them snatching the briefcase with a frightened face, and then saw that the lock of the briefcase was not locked-

In the scramble between the two, the lock of the briefcase was opened, and the contents suddenly poured out-

"Ahh

Subconsciously, Nakajima shouted when he saw this.

Ueda was very puzzled when he looked at his excited expression.

And Takeshita, after seeing the briefcase being opened, suddenly turned pale, and shouted in horror-

"Help!"

Then, subconsciously, Takeshita squatted down and held his head, as if he was dodging something.

- "Huh? Why is it all money? ”

Seeing the stacks of brand-new banknotes wrapped in paper tape that fell out of the briefcase, Nakajima nervously squatted down and hugged these banknotes, looking like he wanted to take them into his arms and protect them, Ueda couldn't help but wonder when he saw this.

And hearing this, Takeshita on the side turned his head to look at Nakajima with a face full of disbelief, and he also showed a puzzled look in his frightened expression-

"Hmph...... Officer Twilight, what's going on, what a show! ”

Looking at the current situation, Conan finally figured out all the details, so he said.

"Brother Maori, what the hell is going on? I'm confused about this? ”

Faced with the successive events in front of him, as well as the unusual reactions of Nakajima and Takeshita, Officer Twilight scratched his head and asked completely incomprehensible.

"What's wrong? Haven't you seen this yet? Mr. Takeshita, you're the one who planted the bomb! ”

Conan shouted in Kogoro's voice:

"That's why he reacted because he thought the bomb he had planted in his briefcase was going to explode."

"Bombs in briefcases?"

Officer Twilight was even more puzzled by this statement.

"Yes, the logo on the briefcase found at the scene of the explosion was bent outward, which means that the impact of the explosion came from the inside, that is, the inside of the briefcase...... Let me start from the beginning! ”

Conan began to explain in Kogoro's voice:

"At first, I was surprised that I heard Conan say that the number plate he used to hear the murdered man withdraw his belongings from the locker would be '98'. You know, when I was queuing at that time, the number plate I got was '96', and Xiaolan received exactly '100', so in terms of the situation at that time, the number in the middle of the two of us should be Mr. Nakajima, Mr. Takeshita, and Mr. Ueda.

"In other words, the person with the number '98' number plate should be one of the three of you. But if that's the case, then why did the man take the '98' numbered ticket to the locker to pick it up? ”

"Could it be that one of them just lost the number plate and was picked up by the victim, and then the victim wanted to claim it?"

Officer Twilight guessed.

"No, if that's the case, then they should have someone who doesn't have a numbered plate in their hand right now, which means it's impossible to withdraw anything from the locker. But now the situation is that they all have their own number plates in their hands, and they have all received things. So Officer Twilight, what you're talking about probably doesn't exist. ”

Kogoro's voice explained:

Therefore, it is more likely that the two of them exchanged number plates than if they lost them. In other words, the briefcase in Mr. Nakajima's hand is actually the one that the victim deposited at the depository. Just ask the waitress at the storage place to find out about this!

After all, the number plate that Mr. Nakajima went to pick up the briefcase was exactly the last number plate in the number plate that was distributed, and because the victim's height was very distinctive, the waitress remembered it very clearly - the victim came back to withdraw the items immediately after depositing the things.

"So, I guess Mr. Nakajima should know the victim who was killed, right? You are putting things in the storage place in this way, and then quietly exchanging the things you bring by exchanging numbered plates - the so-called underground transaction! ”

"I see!"

Officer Twilight suddenly realized, and then thought about it and realized that something was wrong-

"That's not right, Brother Maori, if you calculate it this way, shouldn't the one who stored the bomb in the briefcase be Mr. Nakajima, who traded with the victim? How can you say that it was a bomb planted by Mr. Takeshita? ”

Officer Twilight wondered.

"That's another question, Officer Twilight."

Conan continued in Kogoro's voice:

"At the scene of the explosion, in addition to the logo on the briefcase, didn't you also find the key to the briefcase? Officer Twilight, do you think that is the key to which briefcase is it? ”

"Of course it's the briefcase on the scene, otherwise ......"

Said it as a matter of course, but when he thought of the tone of Kogoro's voice, Officer Twilight still changed his words in confusion:

"Isn't it?"

"Officer Twilight, won't you just try it?"

Conan said in Kogoro's voice, but he couldn't say the reason for his judgment—

The words like "can't get in" and "open mile" heard in the bug before should refer to the fact that the key obtained does not match the keyhole of the briefcase, but the briefcase does not mean to be locked.

But since this is the content of the eavesdropping, Conan can't say it openly, so he can only say it in such a roundabout way.

"Technical Section!"

In response, Officer Twilight hurriedly called the technical officers at the scene and asked them to quickly compare the key at the scene with the remaining keyhole they found.

Due to the small size of these two things, they were directly blown away by the impact force when they were exposed to an explosion, but they were not subjected to too much pressure and caused obvious deformation.

So, after careful comparison by the police officers of the technical section, they came to a conclusion with great certainty:

"Officer Twilight, this key doesn't open the lock."

In this regard, Officer Twilight hurriedly asked Kogoro:

"Brother Maori, what the hell is going on!"

"Officer Twilight, the format of this key is the same as the key to the briefcase issued by the Mantendo Company, so it's clear that this key is used to open the locks on the briefcase...... I guess this is what Mr. Nakajima gave to the man along with the number plate, right? But now, since this key can't open the lock on the spot, it can only mean one thing - the briefcase that the man got at the storage office is not the briefcase that Mr. Nakajima deposited! ”

Conan explained in Kogoro's voice:

"And if you want to know what's going on, just find out who has the briefcase that the key can open, and everything will be clear......"

"I see......"

Before he finished speaking, Yunobu Takeshita, who was still squatting on the ground, suddenly stood up with a gloomy face, and said in disbelief:

"That explosion just now is the bomb I planted...... It's a pity that I fabricated a threatening letter to pretend to be a terrorist, but I didn't expect ......"

"Takeshita ......"

Seeing this, hearing Takeshita's words, Ueda and Nakajima looked at him in disbelief.

"Looking for a briefcase that can be opened with this key...... I think, if I'm not mistaken, it should be the one I have in my hand, it should have been Nakajima's briefcase! ”

As he spoke, Takeshita threw the briefcase directly at Officer Twilight.

In this regard, Officer Twilight stretched out his hand to pick up the briefcase in a panic, and took this opportunity, Takeshita turned around and ran towards Nakajima, and then when Nakajima was at a loss, Nakajima was pushed to the ground by Takeshita, and then Takeshita choked his neck and yelled with a hideous face-

"Nakajima! You're the one who should have been blown up! You were the one who killed Liangmei! Now, I've killed an innocent person anyway, and I have nothing to worry about! ”

Shouting, Takeshita tried his best to even the green tendons on his face had flare, and he grabbed Nakajima's throat tightly, watching him struggle with a red face due to gradual suffocation.

However, after all, there is a police scene here, and everyone is watching, and the police on the side immediately launched an operation, and three or four police officers together forcibly pulled Takeshita away from Nakajima, and Takeshita was so far that he could only be taken away by the police with hysterical shouting-

"So ......"

After listening to Takeshita's words, Officer Twilight finally sorted out the truth of the matter-

"That's right, it was Mr. Takeshita who wanted to kill Mr. Nakajima with a bomb, so he should have installed a bomb in his briefcase, and then after they deposited the briefcase in the storage office, he secretly swapped his number plate with Mr. Nakajima's number plate, so that when Mr. Nakajima got back the briefcase of the briefcase, it was naturally the briefcase with a bomb prepared by Mr. Takeshita. Later, when Mr. Nakajima opened the briefcase himself, it was natural that he would be killed by the bomb. ”

Conan summed up in Kogoro's voice:

"It's just that Mr. Takeshita didn't expect that Mr. Nakajima didn't even take his briefcase, but used the number plate to trade with the victim, which led to the victim's death."

"So, the dead died in vain......"

Officer Twilight couldn't help but sigh a little about the truth of this incident, and then looked at the name "Yoshimi" that had been shouted in the mouth of Takeshita, who was taken away, and couldn't help but turn his head to Nakajima and Ueda and asked:

"Who is Yoshimi?"

"She was the manager of our boxing club in college and committed suicide after being dumped by Nakajima......"

Speaking of this old incident, Ueda also explained helplessly.

"Suicide? But why did Mr. Takeshita ...... for this girl?"

Officer Twilight wondered.

"Because Yoshimi was Takeshita's girlfriend originally, she has been dating since middle school, but she didn't expect to be ...... by Nakajima in college"

Saying this, Ueda was also a little resentful about the old friend he had known for many years-

"So, Mr. Nakajima, who narrowly escaped?"

At this moment, Kogoro's serious voice sounded again:

"It's your turn to give your business!"

"Huh?"

Nakajima lowered his head in a little panic because of Ueda's words, but when Kogoro's words were spoken, his expression suddenly became extremely flustered-

"The man in black who made the deal with you...... Who the hell is he! ”

Roaring loudly, Conan shouted urgently, as if the suppressed emotions were about to burst out at this moment-

"This ......"

Hearing this, Nakajima, who wanted to speak, took half a step back with a frightened face, his eyes widened, and he seemed to feel an aura that scared him even more-

"You chose to trade in such a cover-up way, and you got paid so well...... You must be a shady deal! ”

However, when Kogoro's voice sounded again, the tone of his voice had become less intense than just now, but a bit like a girl's tone-

It turned out that when he noticed that Conan's emotions were about to be uncontrollable, Xiao Ai hurriedly ran to Conan's location, snatched Conan's bow voice changer, and didn't give him a chance to continue talking.

And in this regard, seeing Xiao Ai's reaction, Conan, who was originally suppressing his emotions and wanted to ask in one breath, wanted to take the voice changer back again, but after seeing Xiao Ai suddenly look at him coldly with some warning eyes, Conan, who didn't want to talk to Xiao Ai about this, snorted coldly, so he simply ran out from behind the pillar, took the key from Officer Twilight's hand, and was about to open the briefcase-

"Conan!"

Officer Twilight couldn't help but be taken aback by Conan's behavior, but seeing that the briefcase he opened was a series of documents with various names and related resumes, Officer Twilight also asked Nakajima suspiciously-

"What are these things? Why did that man spend so much money on these things! ”

As a police officer's instinct, Officer Twilight seems to have sensed that something is wrong.

"These ...... I smuggled it out of the company...... A list of the world's most capable computer software designers...... I don't know why they're spending so much money on these ......."

Seeing that the matter had been exposed in front of the police, Nakajima simply confessed.

And listening to the tone of what he said, Conan frowned slightly, and asked directly regardless of it:

"They? Who are they! How much do you know about them! ”

In this regard, Xiao Ai was behind the pillar, turned off the switch of the voice changer helplessly, and let out a long sigh-

After all, he still couldn't be stopped...... However, this person called Nakajima shouldn't know what is going on, after all, the organization will not casually disclose the news of the organization to unrelated people......

"I don't really know anything......"

Probably because today's successive encounters made Nakajima mentally exhausted, and after facing the children's questioning, he simply confessed directly:

"It's just that the place of each meeting is fixed, that is, in the big black building on Rice Flower Street, the bar on the top floor, called 'Cocktail'."

Hearing this, it seemed that he had finally found some useful clues, and Conan simply ran out and ran towards the outside of the hotel-

"Edogawa!"

Seeing this, Xiao Ai looked panicked, and hurriedly chased after Conan-

"Cocktail" bar? It's a common junction for the organization, and it's said to be the stronghold of one of the organization's intelligence experts, so if you rush over there......

Not daring to imagine the consequences, Xiao Ai knew that he had to stop Conan.

However, when Conan just arrived at the door, he saw Dr. Asasa's golden Beetle, which stopped at the door at this time-

"Doctor!"

Seeing that Dr. Asa was here, Conan directly opened the car door, sat in the car, and hurriedly shouted:

"The Big Black Building on Rice Flower Street! Hurry up and send me over! ”

"New, New ......"

In this regard, Dr. Asasa was a little surprised by Conan's sudden entry into the car, but saw that Xiao Ai also quickly came out of the hotel, and shouted directly to Dr. Asa after getting in the car:

"Dr. Asasa, you must not go to that bar......"

"Less verbose!"

Conan saw that Xiao Ai was trying his best to stop it, and yelled at Xiao Ai very angrily:

"I finally found a clue, how could I just give up!"

"Bang-"

However, as soon as Conan's voice fell, a huge explosion came straight from a distance-

"That direction...... It's the Big Black Building! ”

Conan was shocked.

Because the Rice Flower Hotel where it is now is located is at the end of Rice Flower Street, even if you look at it with the naked eye, you can see the top floor of a building not far away, and at this time there is billowing smoke and fire, as if there has been an explosion!

"Doctor, get over here!"

Although he had already guessed what was happening, he was still a little unwilling, and Conan shouted at Dr. Asasa.

And the matter has come to this point, and Xiao Ai will no longer stop it - anyway, now that it has passed, there will definitely be nothing to be found!

So, when Conan and the others came to the downstairs of the big black building and saw that the top floor of the entire building was blown up, Conan, who was very unwilling, thought of another clue-

That is, that university professor named Masashi Hirota!

……

"Although it happened suddenly, there was a plan in the end...... Hey, don't worry about leaving this kind of thing to me. ”

At this time, outside the big black building, a man in a light-colored suit, with short blond hair and dark skin, made a phone call, went straight through the crowd, and said to the person on the other end of the phone......
