"You haven't left yet, Furuta-kun?"

"Ah, I still have some things on hand, Doihara-senpai!"

When the day's work was over, colleagues in the same department went back one after another. Seeing Ichiro Furuta still working at his desk, senior Doihara who was passing by couldn't help but came over with some curiosity.

"This is the Shinagawa Railway Bridge case. Didn't it come to a standstill temporarily because the identity of the victim could not be determined?"

"Hey, but... I want to try from other aspects to see if I can find some new clues!"

"Ha... It's better not to worry about the case. If you are not in a hurry to go home, just go have a drink with me! Man? Occasionally... there are times when you don't want to go home directly, but take a detour to have a drink!

"

"Oh well!"

Ichiro Furuta hesitated for a while, but finally decided to follow Doihara-senpai's suggestion and find a place to have a drink together. Because he also knew that nothing in the workplace could bring us closer together than drinking together.

Ichiro picked up his coat from the chair, then packed his briefcase and left the office with Doihara-senpai. When the two walked to the elevator, they happened to meet Maeda Shinpachi who was about to leave after get off work.

"Maeda-kun, Ichiro and I are going to have a drink. How about...are you interested in joining us?"

"Really? That's great. Anyway, I'll be alone when I go back!"

As Maeda Shinpachi said, he happily agreed to Doihara-senpai's invitation. After the three of them got off the elevator, they took a car together to a tavern in Ichigani Bancho.

"Welcome, ah... Doihara-san, it's been a long time since we came to our place!"

"Long time no see, boss lady! I have a rare free time today, so I came here with my colleagues! By the way, please give us some edamame (edamame), lengnu (bonito flower cold tofu), and salted cuttlefish.

Also, here’s some beer! We’ll order the rest later!”

Mr. Doihara ordered a few side dishes to go with wine with ease, and it seemed that he was a regular customer here. After the three of them sat down, the store first served them beer and homemade pickled side dishes, and then Mr. Doihara enthusiastically served them to them.

Someone poured the beer.

"Ah... the work of searching the first class is really energy-consuming! I really look forward to the days when I can come here and have a few drinks every day after retirement!"

After a few glasses of beer, Mr. Doihara casually pulled off his tie and even spoke more casually.

"Furuta-kun, the cases on our hands will never be fully investigated. The identity of the victim in the Shinagawa case is still under investigation. I think... you should take advantage of this time to have a good rest! After all, we have even died.

If we don’t know who the victim is, how can we continue to investigate this case?”

"Hey, thank you for your teachings, senior! I just...want to give it a try and see if I can put aside the victim's identity and investigate the case from the murderer's perspective!"

"Eh... from the murderer's point of view? How to investigate?"

When they heard Furuta say that they wanted to investigate the case from the murderer's perspective, Maeda and Doihara suddenly became curious.

"Ah...that's actually what happened! Recently, I heard someone accidentally mention that there is a search method that starts with the murderer's criminal behavior pattern and launches an investigation. The specific principle is that once certain suspects are used to a certain

If you follow a criminal procedure, you will continue your criminal steps... You dare not adapt your own criminal methods easily! So... I just want to try and see if I can let Shinagawa's case solve the current impasse! "

"Pattern of criminal behavior? What was that..."

"It seems to be a search method developed by the FBI in the United States! It is said to be very effective in tracking down serial criminal suspects!"

"Eh... Mr. Maeda also knows this?"

Hearing Maeda Shinpachi mention the FBI, Furuta Ichiro became even more curious.

"Ah...that's not true! Actually, I don't quite understand it either! But...it is said that there were bureaucrats in the promotion group who went to the United States for further study and received training in this field. After they came back, they once wanted to promote it in the Metropolitan Police Department.

A new type of search technology, but... then nothing happened!"

"Promotion team? When did those guys participate in the search work of the first class? Every one of them just wants to climb to a higher position!"

Doihara complained drunkenly, and Shinpachi on the side listened, but couldn't help but sigh:

"Yes! But...the only ones who can go to the United States for training are the bureaucrats in the promotion group!"

Hearing the conversation between Madoka Doi and Maeda, Ichiro Furuta couldn't help but feel a little surprised. He didn't expect that... this novel search technology was actually brought back from the United States! Unfortunately, those who were sent to the United States for further study were those with basic skills.

Even if those guys are sent to the United States to learn these things, they probably won't really focus on this, even if they are sent to the United States to learn these things.

Those elite bureaucrats who are called professional groups all graduated from prestigious universities. They finally entered the Metropolitan Police Department by taking the National Class A Civil Service Examination with a very low admission rate. It is for this reason that the Metropolitan Police Department’s

Secretariat positions are almost exclusively occupied by bureaucrats from these occupational groups, while civil servants like Ichiro who only have a high school degree can only hold some auxiliary positions!

However, in actual daily work, it is non-professional team members like Ichiro and others who participate in case investigations.

"But...then again, Furuta-kun! You said you would investigate the murderer's criminal behavior pattern. What are your plans?"

Mr. Doihara drank another glass of beer, and then asked Furuta Ichiro about his plan. At this time, Furuta Ichiro was worried that there was no one to help him. Seeing that Mr. Doihara seemed to be very interested in the matter, he hurriedly introduced him.

road:

"I want to try to search among the remaining cases of the Metropolitan Police Department to see if there are any similar situations to the Shinagawa Rail Bridge case. According to my speculation, the murderer's committing skills in the Shinagawa Rail Bridge case were very special.

Mature, there were almost no clues left at the scene that would be helpful to our investigation! I was just thinking that he must have done similar cases before!"

"Is there any leftover search? This is going to be difficult! If you want to find it, it's like looking for a needle in a haystack!"

"On this point, senior! I don't think the situation will be particularly bad! We may be able to screen out some useful characteristics of the track bridge cases first to identify the cases left over from the past!"

"Useful features? You mean..."

“The hands were tied behind the back with ropes, the victim was a female, and the place where the body was dumped was a track bridge! In addition, we can determine that the time of committing the crime and dumping the body was at night, and, by the way, there was also the weather on the night of the crime.
