Stay away from Conan.

Based on his understanding of the original work, Takato subconsciously believed that the fact that the murderer had deliberately stuffed the police manual into Shiba Ichiro's hand during the second murder was because the murderer, Kazato Kyosuke, was Shiratori's attending physician. Therefore, he was able to easily extract information from Shiratori that "the police judged that Narasawa's actions before his death were hinting at the police manual."

However, given the short interval between the two incidents, it is unlikely that even Officer Shiratori would have been tricked into revealing information by Kyosuke Kazato at that time, thus creating a second incident.

Therefore, after Inspector Shiratori and his team received the anonymous email from Takato and re-examined the possible sequence of events, they realized this—

How did the murderer so quickly learn that the police interpreted Narasawa's actions before his death as referring to the police handbook, and then use this to his advantage in the second incident, leading the police to misjudge the direction of the investigation?

This is currently a blind spot in Gao Yuan's vision; it's a difference he hasn't yet realized, so he can't glean any further clues from it.

Having no further thoughts for the moment, Gao Yuan decided to rest. However, he didn't choose to go back to his room upstairs; instead, he lay down and fell asleep on the sofa in the basement.

After all, even if any unexpected situation occurs, at least for now, the basement of what's called "The Tower" is still not easily breached by outsiders...

……

In the Metropolitan Police Department and interrogation rooms—

After Officer Shiratori finished analyzing the situation and assigning tasks to Miwako Sato and the others, he went to the interrogation room to check on the progress of the interrogation. After all, if it weren't for the email that caused him some delay, he had originally planned to come and check on the progress as well.

Thus, when Officer Shiratori entered the room next to the interrogation room and looked through the one-way glass at the interrogation room, he saw Tomonari, who was being interrogated by the officers. Tomonari was visibly exhausted, and it seemed that the interrogation hadn't made any significant progress so far.

After all, Inspector Megure and his team, who were also there observing the situation inside the interrogation room, had their brows furrowed, seemingly finding the matter extremely troublesome.

Therefore, he secretly breathed a sigh of relief, knowing that at least for now, Yu Chengzhen should not have admitted to the crime he committed, so there was still room for maneuver.

So, Officer Shiratori feigned confusion and looked at Inspector Megure, asking in a low voice:
"how's it going."

In response, Inspector Megure glanced at Officer Shiratori, who had just entered, then turned his gaze back to the one-way mirror, looking at the situation inside the interrogation room, and said:
"There's still no progress... However, he can't explain why we found that phone on him..."

Thus, Officer Shiratori had somewhat anticipated this outcome, and after thinking for a moment, he tentatively asked:
"Inspector Megure... do you think there might be another possibility in this matter?"

—After all, if Yuzuru wasn't the murderer, he couldn't possibly have planted the bomb. Therefore, the cell phone signal used to detonate the bomb couldn't have come from him. And now it seems even the cell phone found on him doesn't belong to him. Could it be that the real murderer placed that phone on him? Hearing Inspector Shiratori's words, Inspector Megure paused for a moment, seemingly considering this possibility as well.

Because, to be honest, the murder weapon that killed the two police officers has not yet been found, and ultimately, the cell phone is only some auxiliary evidence and cannot directly prove that the person who owns the cell phone is the murderer who killed the two police officers.

However, in Inspector Megure's view, if things weren't like this, and the culprit was someone else, then this whole affair would be extremely difficult to explain—

Why is it that, by sheer coincidence, the person you catch becomes your true friend?

Faced with this question, Inspector Megure lowered his head in thought, but couldn't come up with a better solution. Just then, the door to the interrogation room was pushed open—

Then, Matsumoto Kiyonaga pushed open the door and entered, looking at everyone present with a serious expression.

The police officers present, especially Inspector Megure and Inspector Shiratori, were also surprised. They wondered why Matsumoto Kiyonaga had suddenly come over. Was it because he was taking the incident very seriously?
Thus, before Inspector Megure and the others could even inquire about Matsumoto Kiyonaga's purpose, Matsumoto Kiyonaga, upon seeing Inspector Megure and Inspector Shiratori present, immediately said:

"Oh, Megure and Shiratori are here. Perfect, I need to talk to you."

Upon hearing that Matsumoto Kiyonaga had come to see them, Inspectors Shiratori and Megure didn't think much of it and immediately responded. Inspector Megure first instructed the other officers present to continue monitoring the interrogation, then he and Inspector Shiratori followed Matsumoto Kiyonaga out to his office.

"Manager Matsumoto, what happened?"

Upon arriving at Matsumoto Kiyonaga's office, Inspector Megure noticed that Matsumoto Kiyonaga's expression was very serious. Moreover, given that it was so late at night, the fact that Matsumoto Kiyonaga, as the supervising officer, was present at the Metropolitan Police Department and had specifically summoned Inspector Megure and Inspector Shiratori from the First Investigation Division meant that something very important had happened to warrant such an urgent summons. Therefore, Inspector Megure couldn't help but ask.

From Officer Shiratori's perspective, initially, when he was in the locked conference room with Miwako Sato and the others, they encountered Manager Matsumoto who knocked on the door to inquire about the situation. At that time, Manager Matsumoto only asked about the situation and didn't have anything special to say. But now, Manager Matsumoto's attitude is completely different. It seems that Manager Matsumoto must have come back to the office late at night to deal with something.

As a result, Officer Shiratori was also nervous. It seemed that something even more important had happened. Compared to the current murder of the two officers, what other event could have moved Superintendent Matsumoto so much?

Thus, after being questioned by Inspector Megure, Matsumoto Kiyonaga sat in his office seat, his expression serious, and pushed a stack of documents in front of the two men before explaining:

"Several murders have recently occurred in Tokyo, Kanagawa, Shizuoka, Nagano... and other areas. Based on the circumstances at the scene, it's possible this is a serial murder case involving multiple locations!" (End of Chapter)
