"Senior, is there any connection between the taxi and this arson case?" After getting in the car, Naoki Kamii felt vaguely that he had grasped something, but he couldn't connect the dots.
"Think about it carefully." Tang Ze smiled slightly: "This is the key clue."
"I understand." After knowing that this was a test from Tang Ze, Naoki Kamii felt relieved.
This also proves that Detective Tang Ze has seen through the truth of the case and even found the criminal, which is why he tested himself.
So while he was on the road, Naoki Kamii's brain started to work separately and he began to think.
But halfway through, Naoki Kamii still had no clue. He sighed and subconsciously glanced out the window, wanting to see how much time he had left to think.
"Eh? Senior, this doesn't look like the way back to the Metropolitan Police Department, does it?" Naoki Kamii glanced at the scene on the roadside and quickly realized: "Is this the Scientific Research Institute?"
"That's right. Do you have any idea?" Tang Ze asked with a smile while driving.
“I didn’t before, but now I seem to understand.”
When Naoki Kamii realized that Karasawa planned to return to the Institute of Scientific Research and that he might be doing an experiment, he immediately thought of the connection between taxis and electric stoves.
"Oh? Tell me about it." Tang Ze said with a smile.
"Is it the radio?"
After all, Naoki Kamii is also the chief of the next generation of Karasawa, and he has good abilities. Moreover, during the time he has been working, he has either been with Karasawa or working with Takagi to solve cases on Kogoro Mori's side.
It can be said that in this kind of high-intensity case, Naoki Kamii gradually became a qualified criminal.
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 the company, otherwise he would have become a tool.
After hearing the answer given by Naoki Kamii after thinking about it, Tang Ze nodded with satisfaction.
Then the two of them came to the Scientific Research Institute and took two things that Saito Hiroshi had already prepared.
Radio stoves and intercoms manufactured by Air Electric.
"Then let's start the experiment."
Tang Ze nodded to Saito Hiroshi, who unplugged the electric wire from the electric stove and placed it on the table.
After that, Saito Hiroshi turned on the intercom and began to adjust the frequency.
After tuning to a certain frequency, the intercom placed on the table turned on automatically without anyone touching it.
"So what Kurosawa Tomoyo said is true. These three arson cases were not committed by the other party, but were caused by the radio frequency of the intercom?"
After confirming his guess, Naoki Kamii clenched his fists, as if he was happy that he had found the answer.
"That's right. I think Xiao Yanagizu Kiriko also discovered this, so she stayed at night to conduct experiments."
Tang Ze said, "You know, every taxi has a different intercom frequency. The other party took a different taxi to test which taxi company's frequency the electric furnace would respond to."
As a person who lived in an era of continuous technological advancement in the past, Tang Ze has a much broader vision than people in this backward era.
The cordless stove may be a new innovation now, but for Tang Ze it is a commodity that can be seen everywhere.
In the future, you can download an app on your phone to turn on the air conditioner. So, considering that Koyanagizu Kiriko has been coming home late recently, Tang Ze quickly concluded that the intercom in the taxi might have caused a problem with the heater.
"What kind of radio wave is that? Does it correspond to the frequency range of wireless taxis?" Naoki Kamii quickly looked at Hiroshi Saito.
"Before you came, I had already done experiments, and after comparison, I found this company."
Saito Hiroshi took out a table listing the intercom frequencies of various companies. After comparing it with the frequency on the intercom screen, he found that this frequency was consistent with the frequency of the rental company "Captain Chengfeng"!
"This... this is the taxi that Koyanagizu Kiriko took the night she was murdered!"
After seeing the rental company with the corresponding frequency, Naoki Kamii was surprised and said, "So, the death of Kiriko Koyanagi was an accident..."
As soon as he said this, Naoki Kamii shook his head and denied this statement: "No, it's obvious that Ms. Koyanagi prepared the fire extinguisher in advance. It's impossible for the other party to be buried in the sea of fire...
So fire and homicide cases should be separated!
After Koyanagizu Kiriko was killed, the taxi she called also arrived downstairs of the company.
It just so happened that the intercom frequency of the "Captain Chengfeng" we called today could turn on the heater, which turned an ordinary murder case into an arson case.
"Good analysis, that's the basic situation."
Tang Ze nodded. "The remaining two arson cases have now been resolved. Let's tell Inspector Yumio about this and have him contact the relevant departments to investigate 'El Electric'."
"But, Senior, this has made the murder of Kiriko Yanagizu even more confusing."
Naoki Kamii said seriously, "Those people at the top of the company had a motive to kill the deceased in order to keep this scandal secret."
"No, the criminal 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 people in front of him with some uneasiness: "Um...did I do something?"
"Mr. Harada, I think you should be the most clear about this matter, right?" Tang Ze looked at the young man in front of him and smiled slightly: "Since I invited you here, you should have some guesses, right?"
