Detectives of Detective World

To be able to catch Tomo Kurosawa is actually a good result.

At least the subsequent arson cases can be curbed.

At the same time, it also helped Tang Ze to eliminate a layer of "smoke bomb" shrouded in the murder case.

After eliminating the smoke bombs, Tang Ze began to sort out the case with an ordinary judgment of murder, arson and destruction.

In this way, he can maximize his objective judgment on all clues.

So he asked Naoki Uai to bring the information on the arson case, and then confirmed one thing.

In the two cases that Kurosawa denied, the ignition devices used were electric furnaces, and they were both of the same type.

If you add the Koyanagizu Kiriko case, then the three cases have similarities.

When Tang Ze informed Naoki Kamai of the situation, when he saw the electric stove that was burned to black and white in the photo, he couldn't help but be surprised: "Why is it all this wireless stove?"

"Look, this electric furnace was burned in the warehouse of this IT club." Tang Ze pointed to the contents of the document: "In other words, there is no socket connected."

"Did the prisoner use the electricity remaining on the circuit to turn on the electric furnace, and then use it as the ignition point to commit the crime?"

Naoki Uei speculated after hearing the words: "But it's a bit strange. How did the prisoner know that the heater had electricity."

"Do you think only people turned on the electric stove?" Tang Ze pointed out some information and said, "I think something turned on the stove automatically and caused the fire."

"Eh? Automatically open?" Naoki Uai was surprised: "But how is this possible..."

"Why not?"

Tang Ze tapped the jet-black electric stove on the photo and said, "Don't forget, this is the latest design.

And since there is no previous experience, there may be defects, right?

Don't forget what kind of person Koyanagi Tsutoko is. "

"Senior, are you saying that Koyanagi Tsutoko returned late at the labor union office recently, just to investigate the defects of this heater!?"

After hearing Tang Ze's words, Naoki Naoki quickly reacted and understood what Tang Ze meant: "Then the senior management of the company are very suspicious!"

"Let's not talk about that, we need to find evidence from Koyanagi Tsutoko's investigation to prove it."

Tang Ze asked Naoki Naoi to identify the physical evidence collected by the Kona Trade Union Office, the focus was on the paper materials.

However, because of the fire, most of these paper materials were burnt and tattered, and more were turned into fuel for flames after the fire.

But even so, there is still a very high stack of paper left.

"Senior, what we are looking for is the record of the deceased's investigation of the electric furnace, but has this record been recorded or simply destroyed in the fire..."

Naoki Uei rummaged through the papers while taking a pessimistic view of the work at hand.

"No, it's not as troublesome as you think, you've overlooked a very important point."

Tang Ze opened his mouth and said, "Ya Shimo also said before that Koyanagi Tsutoko has been taking a ride home recently, which is a bit unusual."

"So we still have to find an invoice?" Naoki Uai said, and found that an invoice appeared in the documents he was looking for.

"It's an overtime invoice called Kamijose." Naoki Uai looked at it and said, "It's from Shunli Transportation Company, not the deceased."

"I found one here. It belongs to the same company as yours." Tang Ze shook the invoice in his hand.

The two kept rummaging, and they quickly screened out Koyanagizu Kiriko's recent taxi receipt, and discovered the problem.

That is the invoices issued by these taxis, each of which is issued by a different taxi company.

This is very strange. Tang Ze and the two also looked for other people's taxi invoices, but found that all of them together did not have the complete invoices for Koyanagi Tsutoko's taxi.

Of course, this complete does not refer to anything else, but to the invoice of the taxi company.

Smooth traffic company, traffic traffic, KM wireless, boat song traffic company...

Invoices issued by various transportation companies are included, because there are dates on them, so the two quickly arranged the vehicles that each other took during this period in order.

Unfortunately, these invoices are only up to the day before the incident, and it is not clear which taxi of the transportation company Koyanagizu Kiriko took on the day of the incident.

However, the physical evidence could not be found, and the two still have witnesses to this method.

So Tang Ze and the two went to the company again with the invoice for Koyanagi Tsutoko's taxi, and visited Yamashita and Harada.

"Ms. Koyanagi has been taking a different taxi every night recently. May I ask which company rented it on the day of the fire?"

Spreading out all kinds of invoices on the coffee table, Tang Ze explained the purpose of this visit to the two of them.

"I remember... that night seemed to be the rental of "Captain Riding the Wind"." Harada Maya recalled after hearing Tang Ze's words.

"It's a different rental company..." Tang Ze nodded knowingly, and a light flashed in his eyes.

"This should be your company's taxi invoice, right?" Takagi said, and picked up a invoice: "I think, except for Ms. Koyanagizu, most of you use this taxi with smooth traffic."

"That's right, our company cooperates with Shunzhou Traffic. Under normal circumstances, we only rent Shunliang Traffic."

"I understand." Tang Ze nodded, got up and said goodbye to the two.

Although this visit was short, it completely confirmed Tang Ze's speculation.

"Senior, does the taxi have anything to do with the arson case this time?" After getting into the car, Naoki Uei felt that he had caught something, but he couldn't connect it.

"Think about it." Tang Ze smiled slightly: "This is the key clue."

"I see." Naoki Kamai heaved a sigh of relief after knowing that this was Tang Ze's test.

This also proves that criminal Tang Ze has seen through the truth of the case, and even found the culprit, so he will test himself.

So in the process of hurrying behind, Naoki Kamai's brain started to think separately.

It's just that Naoki Uei still didn't have a clue until he was halfway there. When he sighed, he looked out the window subconsciously, wanting to see how long he had left to think.

"Huh? Senior, this doesn't seem to be the way back to the Metropolitan Police Department, right?" Naoki Uai glanced at the scene on the side of the road, and quickly reacted: "Is it from Science Research?"

"Yes, do you have any clues over there?" Tang Ze asked with a smile while driving.

"It wasn't there before, but now I seem to understand."

When Naoki Uai realized that Tang Ze was planning to go back to science and research, and realized that the other party might be doing experiments, he immediately thought of the connection between taxis and electric furnaces.

"Oh? Let's talk about it." Tang Ze said with a smile.

"Is it the radio?"

After all, Naoki Uai is also the chief of Tang Ze's next term, and his ability is good, and during the time he joined Tang Ze, he was either by Tang Ze's side or with Takagi to solve the case on Mouri Kogoro's side.

It can be said that Naoki Naoki has gradually become a qualified criminal under such a high-intensity case.

Of course, the reason why he didn't lie down was because of the ideas that Tang Ze had instilled in him since he joined him, otherwise this guy would become a tool man.

After hearing Naoki Naoki's thoughtful answer, Tang Ze nodded with satisfaction.

Then the two came to Kesouyan and brought two things that the other party had already prepared from Hiroshi Saito.

Radio stoves and walkie-talkies made by Air Electric.

"Then let's start the experiment."

Tang Ze nodded towards Saito Hiro, who unplugged the wire behind the electric stove and put it on the table.

After that, Saito Hiro turned on the intercom and started to adjust the frequency of the intercom.

After tuning to a certain frequency, the walkie-talkie placed on the desktop turned on automatically without anyone touching it.

"So what Kurosawa said is true. The three arson cases were not committed by the other party, but because of the radio frequency of the walkie-talkie?"

Naoki Naoki confirmed his guess and clenched his fist, as if he was happy to find the answer.

"That's right, I think Koyanagi Tsutoko also discovered this, so she stayed at night to experiment."

Tang Ze said: "You must know that the intercom frequency of each taxi is different, and the other party takes a different taxi, also to test the frequency of which taxi company this electric furnace will respond to."

As an era living in an era of continuous advancement of technology in the previous life, Tang Ze has a much broader vision than people in this backward era.

The wireless stove may be the latest innovation now, but for Tang Ze, it is a commodity that can be seen everywhere.

In the future, the next software on the mobile phone will turn on the air conditioner, so considering the abnormality of Koyanagi Tsutoko's late return recently, Tang Ze quickly judged that the intercom on the taxi may have caused the problem of the heater.

"What kind of radio wave is that, corresponding to the radio frequency zone of the wireless taxi?" Naoki Uai hurriedly looked at Hiroshi Saito.

"Before you came, I had already done experiments, and I found this company after comparison."

Saito Hiroshi took out a table listing the frequencies of the intercoms of each company, and after comparing them with the frequencies on the intercom screen, he found that the frequency was the same as that of the rental company "Captain Ride the Wind"!

"This... this is the taxi that Koyanagi Tsutoko took the night when he was killed!"

After seeing the rental company of the corresponding frequency, Naoki Uei said in surprise, "So, Koyanagi Tsutoko's death was an accident..."

As soon as he said this, Naoki Uei shook his head and denied this statement: "No, the fire extinguisher was obviously prepared by Ms. Koyanagi in advance, and the other party could not be buried in the sea of ​​​​fire...

So fire and homicide cases should be separate!

After Koyanagizu Kiriko was killed, the taxi called also came downstairs of the company.

And the frequency of the walkie-talkie of "Captain Chengfeng" who happened to be called today can turn on the switch of the heater, which made an ordinary murder case join the arson case. "

"The analysis is good, the basic situation is like this."

Tang Ze nodded, "The remaining two arson cases have now been explained. Please tell the police department later and let him contact the relevant departments to investigate "Aier Electric"."

"It's just a senior, so the case of Koyanagi Tsutoko's murder is lost again."

Naoki Uei said with a serious look: "Those at the top of the company all have motives to kill the dead in order to protect this scandal."

"No, the prisoner has been exposed unintentionally." Tang Ze smiled and said, "Let's invite him over next."

 …

In the interrogation room, the young man in a suit looked at the two in front of him with some unease: "That... what did I do?"

"Mr. Harada, I think you should be the most aware of this matter, right?" Tang Ze looked at the young man in front of him and smiled slightly: "Since you were invited here, you should actually have some guesses, right? "

"You suspect that I am a prisoner!?" Harada was a little furious when he heard Tang Ze's words: "How is this possible..."

"Do you remember what you said when we were holding the invoice?"

Tang Ze directly interrupted Harada's words and asked the other party.

"I said that the taxi that Chairman Koyanagi took that night was "Captain Ride Kaze", is there any problem?"

Harada Zhen repeated what he said that day, but there was still a blank expression on his face.

"Looks like you haven't realized the problem."

Tang Ze looked at the other party and said, "We asked you that day, the timeline of the day when the crime happened between you and Mr.

Then both of you said you went home after get off work and never came to the union's office.

But we contacted the taxi company "Captain Chengfeng" and learned from the driver that the taxi called by Ms. Koyanagi was approaching early in the morning, but she didn't get on the bus in the end.

Because she was killed before she got in the car. "

Looking at Makoto Harada, whose face was pale and pupils began to tremble gradually, Tang Ze got up and leaned forward, looking down at the young man in front of him with sharp eyes like a knife and said word by word:

"That is to say, the fact that Ms. Koyanagi called "Captain Chengfeng" for a taxi, only those who were still in the company at the time knew about it!"

Tang Ze's interrogation made Harada's body tremble even more, Naoki Kamai shouted when he saw this slap on the table: "That night, let's be with Ms. Koyanagi, but you concealed the fact!

In the end what happened! ! Did you kill Koyanagi Tsutoko? ? "

"I…"

Harada was immediately shaken by this ~www.wuxiamtl.com~ but he quickly calmed down.

Harada Mako slowly lowered his head, looked at the ring in his hand, his face showed a complex color like laughter or crying, there were memories and sweetness, but more of it was pain...

But with a hint of relief, Harada Zhen told everything that happened that night.

Although Koyanagi Tsutoko is rumored to be an older woman in her forties who has not yet married, she actually already has a lover.

And that lover is him who has only been in the company for two years.

Because they are in the same company and the age difference between the two is too big, they have always maintained an underground relationship.

It was all good at first, but things have taken a turn for the worse recently.
