I'm in Detective Conan, and the system has appointed Batman.

Chapter 504 Let the bullets fly for a while
Conan has already hurried back to the Mouri Detective Agency.

He didn't ask too many questions about Gamo Ryozo, perhaps because the underlying code of Ran Mouri returning home temporarily suppressed his thirst for knowledge. As for whether this guy would have another sleepless night, that was his own business.

Chen En took a sip of coffee.

He felt the special effects of the coffee washing over his body, restoring his depleted physical strength and energy.

Behind her, Ai Haibara's gaze lingered briefly on Chen En's back before she asked,
"Why can't you talk about Gamo Ryozo's matter...?"

"Is there something wrong with Gamo Ryozo himself that led you to decide to get rid of him after your investigation?"

Upon hearing this, Chen En's gaze fell on the second floor of the firm across the street.

His gaze lingered for a moment before he answered.

“I have investigated and found that Ryozo Gamo is a suspect in two murder cases.”

"The suspects in the attempted murder of Kinugasa Sakae five years ago were Gamo Ryozo and Gamo Ryozo's nephew, Shinkyo Isuke. The criminal investigator in charge at the time, Takeoka Isao, was about to confirm that they were the murderers."

"Then suddenly an eyewitness appeared, proving that Gamo Ryozo had an alibi."

"The Tokyo Metropolitan Police Department subsequently released Ryozo Gamo without charge, while the criminal investigator in charge at the time, Isao Takeoka, was subjected to a barrage of criticism by Shinkyo Isamu for wrongly arresting a man, and was eventually forced to resign."

"Two weeks ago, Sakae Kinugasa was murdered in an antique and art shop in Tsukimi-cho. Ryozo Gamo became a suspect again, but after investigation, he was cleared of suspicion of murder once again."

"Then, Gamo Ryozo came to Kogoro Mouri to ask him to investigate the murderer in the murder case that happened half a month ago, or to find evidence that could prove his innocence."

Hearing this, Ai Haibara asked with some confusion,
"So, does that mean Gamo Ryozo was actually the murderer who killed Kinugasa Sakae half a month ago?"

Chen En paused briefly before replying.
"No."

"The person who killed Kinugasa Sakae half a month ago was not Gamo Ryozo. After my investigation, I found out that it was the work of a member of the Nisshin-kai yakuza. After I finished investigating at the headquarters building this afternoon, I took the yakuza member to the Metropolitan Police Department."

"However, because the Tokyo Metropolitan Police Department is extremely busy, they haven't had time to verify it, and it hasn't been made public yet."

—He wasn't just assisting Professor Agasa with the development of scientific research products that afternoon.

After arriving at the headquarters building, he pointed out the problem with Professor Agasa's design direction, then checked the information about Gamo Ryozo at Noah's Ark, further discovered the murder case of Kinugasa Ei, and finally went to open the box of the Mud Gathering member.

After delivering the mud-collecting member to the Tokyo Metropolitan Police Department, he returned to the headquarters building to continue discussing the design direction.

Then someone disguised himself as a black mask and posted a challenge, asking him to save the city.

The Tokyo Metropolitan Police Department mobilized its entire force to search for and defuse the bombs because he was unable to defuse them all within sixty minutes by himself. Therefore, even now, the Tokyo Metropolitan Police Department is probably still detaining the criminal and has not yet tried him.

Hearing this, Ai Haibara nodded thoughtfully.
"So, you believe that the people who attacked Kinugasa Sakae five years ago were Gamo Ryozo and Shinkyo Isuke?"

"However, things from five years ago can't be traced back, can they?"

That's precisely where the trouble lies.

Chen En frowned slightly and said,

"In the case of the attempted murder of Kinugasa Sakae five years ago, there were only two witnesses. One was a female witness who saw Gamo Ryozo and Shinkyo Isuke commit the murder. Her name was Takeoka Natsuko, and she passed away last month."

"The other is a male witness who may have been paid to do the job. He took too much money and was stabbed to death two years ago." "The murder weapon has been sealed up, and Gamo Ryozo's vehicle has been scrapped. Frankly speaking, there is no evidence to prove that Gamo Ryozo and Shinkyo Isuke were the murderers."

"If I want them to go to jail, I'll have to do it in public."

"However, if Gamo Ryozo has already died by the roadside tonight, I won't need to worry about it anymore. To paraphrase Conan's favorite Sherlock Holmes stories..."

Chen En didn't continue speaking, but looked at Kogoro Mouri, who was leaning back in his chair, chugging beer.

However, even though Chen En didn't say it out loud.

Ai Haibara could somewhat guess what Chen En meant by the sentence he mentioned but didn't say.

Therefore, Ai Haibara simply changed the subject and asked in a low voice,

"You mentioned it before, didn't you?"

"Vermouth and Bourbon Whiskey are strategic allies because Bourbon Whiskey knows Vermouth's secrets about that person. However, the current whereabouts of Bourbon Whiskey are unknown, which clearly shows Vermouth's involvement."

"In other words, Vermouth abandoned her original strategic alliance and chose to betray Bourbon whiskey."

"But why is that? Vermouth discovered where Bourbon whiskey kept its secret, thus preventing the possibility of Bourbon whiskey spreading its secret. Why didn't she discover it sooner or later, but of all times?"

Ai Haibara's question was concise and to the point.

—Yes, why did Vermouth discover this secret not earlier or later, but only today?
However, Chen En already had the answer in his heart.

He said in a low voice,

"It is obvious that there is a high-ranking member of the Black Organization infiltrated within the Tokyo Metropolitan Police Department."

"No, it's not necessarily a mole in the Black Organization, because before I modified the files, the higher-ups at the Tokyo Metropolitan Police Department could find out Furuya Rei's undercover identity, and even his code name within the Black Organization."

"Perhaps the criminal organization that previously supported Black Mask has joined forces with the Black Organization."

"The reason why Furuya Rei was transferred from Tokyo to Nishitama City is most likely due to this. And the two-faced people told me that in the past few days, a member of the Gold Watch Group of the Japanese Public Security Bureau suddenly returned to Tokyo."

"I suspect that this member of the gold watch group has some connection with Rei Furuya."

Therefore, I would draw this conclusion—

An unusual glint appeared in Chen En's eyes.

he said,
"The cooperation between that criminal organization and the Black Organization was based on the appearance of this gold watch group member."

"Rei Furuya noticed something was wrong when he was suddenly transferred, so he contacted the members of the Gold Watch Group to help him investigate. However, he was discovered and was eliminated early. So, if my deduction is correct, someone will definitely take action against the members of the Gold Watch Group next."

"I have no way of finding out which high-ranking official in the Tokyo Metropolitan Police Department is an undercover agent for the Black Organization or a member of a criminal organization."

"But I don't need to investigate. I just need to find out who attacked the Gold Watch Group member, then find that guy and take care of him. All the problems will be solved."

"Let the bullet fly for a while."
