Stay away from Conan.

"More than seven years ago, Mr. Kyosuke Kazato was a surgeon at the Tokyo University Hospital, renowned for his exceptional surgical skills. However, during a surgery seven years ago, an accident injured his surgeon's hand, forcing him to leave the operating table. This essentially ended his career as a surgeon. After that, Kyosuke Kazato switched to psychology, becoming a psychologist and working at Beika Pharmacy Clinic..."

"But according to the contents of the email sent by this anonymous person, the surgery that resulted in the accident was performed by both Kyosuke Kazato and Dr. Yasushi Nino. Because Dr. Nino was rumored to have a bad reputation in the industry and was a bad doctor who did not take responsibility for his patients, there were rumors that the accident at that time was deliberately caused by Dr. Nino in order to prevent the then-promising Kyosuke Kazato from being promoted earlier than him..."

After recounting the contents of the email concerning Kyosuke Kazato and Yasushi Jinno, Officer Shiratori couldn't help but sigh:

"So... if all of this is true, then Dr. Ninoboru, who was murdered a year ago, may have been killed by Kazato Kyosuke, who knew the truth..."

At this point, Officer Shiratori couldn't help but look at Miwako Sato. After all, given the case involving Dr. Nino's death a year ago, Miwako Sato, who participated in the investigation at the time, would likely know more about the details.

"Um……"

Noticing Officer Shiratori's gaze, Miwako Sato naturally lowered her head and pondered for a moment before speaking seriously:

"Regarding Yasushi Nino... we did find during our investigation that he had a very bad reputation. So... it doesn't make sense that the police ultimately closed the case of Dr. Yasushi Nino's death as a suicide. After all, this guy doesn't seem like the kind of person who would commit suicide for any reason."

"That means there's currently no point in the email that can refute the possibility of the clues mentioned."

Officer Shiratori concluded after listening to Miwako Sato's words.

Subsequently, Wataru Takagi summarized it as follows:
"Therefore, based on the clues mentioned in the email, there are two directions we can investigate regarding the case of Nino Yasushi's murder—"

"First, there's Toshiya, the son of Department Head Odagiri, who had a dispute with Dr. Ninoya for some unknown reason; second, there's Dr. Kazato Kyosuke, who may have killed Ninoya out of revenge..."

"Regarding this clue about Kyosuke Kazato, we probably need to investigate at the Tokyo University Hospital to confirm whether the accidental hand injury Kyosuke Kazato sustained a year ago is true. If it is, then he is indeed very likely the murderer who killed Yasushi Nino a year ago, and... he is a suspect we completely overlooked during our previous investigation..."

Sato Miwako said very seriously, and that she did not simply believe what was said in the email; she still needed to verify it.

"If the final confirmation is that Kyosuke Kazato did indeed have a motive, then it's not just the case of Yasushi Nino; perhaps... he was also responsible for these two shootings!"

Officer Takagi responded to this seriously.

Officer Shiratori also thought about it carefully and analyzed:
"So, tonight, Mr. Akechi mentioned that Officer Narasawa's gesture of clutching his heart before he died didn't actually refer to the police handbook he had in his pocket, but rather to his heart..."

At this point, Officer Shiratori seemed to pause for a moment, as if he had thought of something, and said seriously:

"Speaking of which, after the Narasawa incident, when we questioned Mr. Mori and the others who were the first to discover the incident, Conan asked a question: why did Officer Narasawa happen to have an umbrella when the rain started so suddenly? Perhaps this indicates that he came from somewhere and was able to grab the umbrella at that moment... Now that I think about it, Beika Pharmacist Hospital isn't actually that far from Beika Park, where the incident occurred..."

Upon hearing this, Sato Miwako's expression also turned serious:
"Officer Narasawa went to see a psychologist because of Inspector Tomonari's matter, and that doctor just happened to be Kyosuke Kazato... If Officer Narasawa was the one who made the diagnosis at that time... then everything seems to make sense! Because it suddenly started raining so hard, Officer Narasawa borrowed an umbrella from the hospital!"
"In this case!"

"Only one question remains!"

At this point, Officer Shiratori's expression became extremely solemn:

"So, the result of tonight's operation was that Inspector Youcheng's son was the one they arrested?"

—Based on these clues, if Kyosuke Kazato is indeed the culprit behind all the incidents, as the clues in the email suggest, then why did the police, based on the discovery of the bomb, deduce the culprit's behavior and set a trap to lure him out at the engagement party tonight, ultimately arrest Tomono instead of Kyosuke Kazato?
At this point, Sato Miwako's expression turned serious as she lowered her head slightly, one hand supporting her chin, as if deep in thought, or perhaps somewhat incredulous.

"There's only one possibility: the murderer knew about the police's plan beforehand, so he found a scapegoat!"

"But I only learned about the scheme afterward. The murderer couldn't have known about these things beforehand, unless... someone among those involved in the scheme leaked information to the murderer! In other words..."

At this point, Officer Takagi's expression also became unusually grave:

"Just as the sender mentioned at the end, the problem with the whole thing now is that there might be a problem within our police force!"

“If Toshiya is involved in the murder of Yasushi Nino a year ago, we can hardly fully trust our colleagues… And even if the real culprit is Kyosuke Kazato, judging from the current situation, there are problems within our police force as well…”

As Officer Shiratori spoke, he looked back at his phone at the contents of the email—

"Therefore, the anonymous sender finally stated that the email was only sent to trusted individuals within the police force, and that any investigation should proceed without disclosing this information to others until the trusted individuals have been identified..."

Officer Shiratori said this while looking at the three people present.

"Since the three of us received this email, it means that in the eyes of that mysterious sender, we are trustworthy people, right?"

Sato Miwako analyzed earnestly... (End of Chapter)
