Stay away from Conan.

"Minister?"

Gao Yuan couldn't help being very surprised when he heard this title read from Goro Otaki's mouth:

"Hattori Heiji's father, Hattori Heizo? Why do you want to see me?"

The head of the Osaka Prefecture Police Headquarters, that is, the father of Hattori Heiji, and the police inspector Hattori Heizo.

However, as the top leader of the Osaka Police Headquarters, apart from the fact that I know Hattori Heiji, I can be regarded as having a relationship with him. Apart from that, I really can't think of any reason for the police supervisor to ask me to meet him by name.

And obviously, just knowing Hattori Heiji was not enough for the police officer to ask Officer Otaki to pick him up the first time he came to Osaka.

In this regard, Gao Yuan couldn't help asking this question.

On the other hand, Otaki Goro didn't explain immediately, but just motioned Gao Yuan to follow him, saying:
"Mr. Wise, time is limited, let's chat in the car."

With that said, Otaki Goro walked ahead and asked Gao Yuan to follow him.

So, although I felt that things were a little strange, since Otaki Goro came to pick me up, I had no reason to refuse. Thinking that the Osaka prefectural police might have something to look for me, Gao Yuan took Xiao Ai and walked out of the station together. Under Goro's guidance, he got into Otaki Goro's private car parked outside the station——

"Huh? By the way, Mr. Wise, who is this child?"

Seeing that Xiao Ai followed Gao Yuan, and thinking about how he was still single when he met Gao Yuan last year, Otaki Goro asked curiously.

"She's the sister of a friend of mine."

Faced with the question, Gao Yuan naturally gave an answer with the words he was used to saying a long time ago, and then sat in the back seat with Xiao Ai, and after Otaki Goro started the car, Gao Yuan asked:
"By the way, Officer Otaki, what happened? Why did the Hattori Police Commissioner want to see me? Also, did Mr. Mori and the others have been called over?"

After thinking about it carefully, I arrived in Osaka a few hours later than Mori Kogoro and the others, and it is possible that, given the situation of Conan and the others together, they may encounter some accidents by accident, so in the face of such a situation, for Chi If you take a step forward, it seems reasonable that Officer Otaki and the others will come to pick you up.

So, based on this idea, Gao Yuan asked.

However, Otaki Goro's next answer denied this possibility——

"It's true that something happened. It was just invited by the minister. It's just Mr. Akechi. Mr. Mori and the others should be visiting Osaka with Heiji and the others..."

Otaki Goro said seriously, and seemed to be apologetic, so he couldn't help but add embarrassingly:
"Speaking of which, Mr. Zhizhi is also a regular guest, but before you come to have a good time, we took up your time as soon as possible. I'm really sorry..."

"No... Since Superintendent Hattori of the Osaka Prefectural Police Headquarters came to invite me, presumably something important happened, right? And he only invited me but not the Maori detective who came one step ahead of me... because of the incident About me?"

Listening to Otaki Goro's remarks, Gao Yuan briefly thought about it, and then replied like this, feeling that the incident mentioned by Otaki Goro seemed a little unusual——

"It is indeed an important case, and it does have something to do with Mr. Wise..."

Otaki Goro did not deny this, and then said:
"Well... Let me think about it, let's explain it from the beginning!"

As he spoke, Otaki Goro slowly described the recent murder incident in Osaka Prefecture——

"Half a month ago, a murder occurred in Toyonaka City. The deceased was a middle-aged man named Nagao Hidetoshi. He was the manager of a convenience store. The place where he was killed was from his work. The convenience store on the way to his home passed by a park. It was the next morning when he was found, and there were no witnesses. The cause of death was being pierced through the heart with a short knife. So far, no suspicious suspects have been found through investigation. .”

Seriously, said Otaki Goro.

As for this, listening to Gao Yuan's narration, he couldn't help but have a sense of déjà vu——

"Pierced through the heart with a dagger..."

Mumbling, Gao Yuan expressed his interest in this.

"Yes."

Nodding his head, Otaki Goro continued:

"The local police station did a serious investigation, but they were still unable to do anything about this incident... And last week, another similar murder occurred in Hirakata City——

"The name of the deceased was Tadayo Nishiguchi. She was the proprietress of an izakaya. She was also attacked on the way home after get off work at night. She was stabbed in the heart with a short knife and died, and there were no witnesses..."

"Serial killings?"

Hearing what Otaki Goro said, Gao Yuan couldn't help asking:

"Apart from the fact that the deceased were all pierced through the heart with a short knife, what else do the two incidents have in common?"

"some!"

Nodding his head, Otaki Goro seemed surprised by Gao Yuan's sensitivity, and immediately replied:
"I don't know why, but the short knife pierced through the wallets in the pockets of the jackets of the two men, and pierced their hearts! Regarding this point, after the first incident, we did not disclose the details of the wallets, so the second The two incidents are unlikely to be the so-called copycats, it should be the same murderer! That is, serial killings!"

With some sighs, Otaki Goro continued:
"However, there are no witnesses to the two incidents, and the locations are more than ten kilometers apart. Currently, the interpersonal relationship between the two victims is being filtered, and no common ground has been found, so the investigation of the incident has been in a stalemate..."

"In both incidents, the dagger that the murderer stabbed into the deceased's heart first penetrated the deceased's wallet, so what's in the wallet?"

Hearing this, Gao Yuan was basically convinced that this was an incident in the original work that he knew about, but he still didn't know why Hattori Heizo came to him——

"Mr. Wise, you are really sharp!"

At this moment, Otaki Goro was completely surprised when Gao Yuan mentioned the contents of the wallet, and then he couldn't help saying:

"The police who investigated the two murder cases separately investigated the two murder cases for a long time, but found nothing. Finally, because the possibility of serial killings was discovered, after the files of the two murder cases were handed over to the headquarters today, the head of the headquarter and the head of Yuanshan immediately pointed out wallets, and found that the driver’s licenses of the two deceased were in the wallets of the two deceased. Therefore, under the instructions of the Minister, we immediately conducted a detailed investigation on the matters related to the driver’s licenses of the two deceased. It was found that, 20 years ago, before they got their driver's licenses, they all attended a sleepover driving class in Hyogo Prefecture!"

Speaking of this, Otaki Goro's expression became very serious——

"In addition, we also found out that the driving training class where the two deceased belonged to 20 years ago, on the day of graduation, an instructor of the driving training class died because of drunk driving! In this regard, we realize that this time The serial killings in the past may have something to do with this incident that year...

"But this time, the reason why the Minister intends to invite Mr. Wise... We found out that among the people who participated in the sleepover driving training class with the two deceased, there was an extremely dangerous person——

"Kiichiro Numabuchi!"

Solemnly, Otaki Goro said the name.

As for this, Xiao Ai, who had listened to Otaki Goro's narration and didn't have much reaction to the incident itself, was suddenly startled when she heard the name...
