According to the intelligence collected by Qian Muliang, the bombing case involving Officer Hagiwara happened three years ago.
As far as Qian Muliang knows, the pH detector has a service life of about one year. The detector in Matsuda Jinpei's hand is very new.
In other words, the other party has kept the old instructions and packaging used by Officer Hagiwara.
Their relationship must have been close.
"The results are out, it's PENT." Matsuda Jinpei looked at the display on the pH meter, "This is a very powerful explosive and is relatively sensitive."
"Thank you." Qian Muliang said.
"Is there anything else you need help with?"
"Finally, I want to confirm, are these photos all traces of the same kind of bomb explosion?"
"This... I can't give a definite answer." Matsuda Jinpei hesitated, "Although it looks very similar, if there are no explosives left at the scene, it cannot be confirmed."
I can't be sure...Qian Muliang thought.
"Thank you very much, Officer Matsuda."
"Well, actually there is no need to use honorifics, just call me by my last name." Matsuda said, and he was now basically sure that the other party was not good at words.
"Can I ask what you are pursuing? If it involves confidentiality, you don't have to say anything."
"The source." Qian Muliang stared at him sharply, "The source of everything."
"Bombs are one of the currencies in the hands of black organizations. Just like rivers, they always have a source." Qian Muliang unconsciously tapped the table with his hand, "I want to uproot these sources."
"Uprooted", Chiaki said the word lightly, but Matsuda made something heavy out of it.
"You can definitely do it." Matsuda said, thinking of Hagiwara Kenji again.
Qian Muliang smiled, this smile was not obvious and disappeared in a flash. He watched Matsuda Jinpei leave.
After the curly-haired police officer left, Qian Muliang put away the photos and glass bottles. He walked to the notice board on the wall and followed the timeline to find it.
"Kenji Hagihara, the bomb suddenly detonated..."
--------------------------------------------------
"... He died three years ago, which is quite a pity." Kawakami Tsumugi browsed the information on the Internet.
Matsuda Jinpei made Kawakami suddenly have a desire to investigate. He thought it was the reason for his curly hair.
It's rare to see such curly hair, and it seems to be natural.
What Kei Kawakami was most curious about was why Officer Matsuda was transferred.
According to his understanding of the Metropolitan Police Department, jobs such as those that can defuse bombs are scarce and in high demand.
In contrast, one or more bombs will randomly appear in Miwa Town every two days on average - although 70% of them are the fault of the winery.
There must be a reason why the police officer switched from the Explosive Ordnance Disposal Squad, which was relatively short of personnel, to the Forced Criminal Search Department, which was not so short of personnel.
First, the ability is not good - Judging from Matsuda's hands, he should be a master of bomb disposal, which can be ruled out;
Second, he is physically incompetent - there is no obvious damage to his hand at first glance, and other conditions are unclear, temporarily doubtful;
Third, psychological reasons - post-traumatic stress disorder, or other purposes, such as revenge or self-adjustment. Although there is no evidence, it is the most likely.
Starting from this point, Kawakami Tsumugi began to investigate the bombings in various places in Mihua Town, and then found Hagiwara Kenji, and continued the investigation along this line.
However, there is not much information available.
There was no sign of Kenji Hagiwara in the police academy recruitment promotions, sororities, etc. Of course, it could not be ruled out that the other party did not like to join in the fun.
Kawakami didn't give up, he checked again, and finally found a photo from a certain social platform.
It was a man with handsome features and slightly longer hair, chatting with four or five women. In the corner of the photo sits Jinpei Matsuda, seemingly talking to someone.
Because of the angle of the photo, Kawakamiji couldn't see who was talking to Matsuda Jinpei.
There is also a sentence under the photo:
[Wow! Captured a rare handsome guy at a sorority party~]
This is a woman's blog, which was set to a private status visible only to her. Kawakami used some extraordinary means to see it.
"It's indeed not bad...much better than the photo in the newspaper." Kawakami took a lemon candy.
This photo is very interesting.
Judging from Hagiwara Kenji's appearance, it is obvious that he is good at sociability. If he joins an organization, he will probably be told to "shut up" by gin at every turn. This kind of person should be the focus of a sorority and the like.
But there are no photos of him on the Internet, not even those of Matsuda Jinpei.
This means that their photos may have been cleaned.
However, the Explosive Ordnance Disposal Squad is not a highly confidential department. Based on this, it may be someone they know who is engaged in highly confidential work such as espionage or undercover, and their photos have also been cleared.
Thinking again that Scotland and this curly-haired police officer may know each other...
So do I need to continue searching... Tsk, I'm a little undecided.
In fact, at this point, Kawakami's interest is almost gone, and there are only two situations: yes, or no. Both situations are pretty boring.
It's not like Gin is in charge. Even if there is a problem in Scotland, being with Kawakami Tsumugi will not cause harm to the organization, and you can also help him share tasks.
Just like his deputy in the research team, Akira Nakamura, because he is very capable and fun to tease. Kawakami Tsumugi and he got along happily for nearly three months.
It wasn't until Nakamura Akira finally tried to trick him that Kawakami Tsumugi had to endure the pain and sacrifice him to heaven.
"Then let's do this -" Kawakami was about to close the computer, but his movement seemed to be stopped by something, "Forget it, let's check for another half an hour."
There is no doubt about Scotland, and it would be unlucky to give up halfway.
30 minutes later.
Kawakami raised his head and rested his head on the top of the back of the chair, staring at the ceiling blankly.
"Tsk, it was deleted very cleanly..."
I don’t know who the person who erased the information was, but that guy deleted things very cleanly, even if he was a little too forceful.
In other words, he found nothing following the two lines of Hagiwara Kenji and Matsuda Jinpei.
Kawakami knew that his level was just like this. If he continued to investigate, he could only report it to the organization and let specialized people investigate.
But that...tsk.
Scotland is his partner, there is no reason for others to investigate.
"Let's put this message aside for now."
At least this trip found out the purpose of Officer Curly's transfer. It was probably to avenge Hagiwara Kenji who died three years ago.
"So, you have to live up to my trust...Scotland." Kawakami murmured softly.
…………
In another room, Scotland, unaware that his partner was talking about him, was checking his browser.
In the lower right corner of the computer screen, an advertisement pop-up window suddenly appeared, similar to the kind of junk advertisement that "sexy lady deals cards online".
Scotland wanted to cross out the small advertisement, but accidentally clicked on it. Behind the poor P-picture, the background was a vulgar pink.
He felt relieved, which meant that the police received his message.
Who knows which of his talented colleagues came up with this way of connecting. Convenient and concealed, there is no suspicion of exposure even if someone sees it.
In addition to the skills of his talented colleagues, Scotland also lamented the pervasiveness of pop-up advertisements, which even the anti-virus software developed by the organization cannot block.
