Ms. Moriarty wants to save Beika Town today too.

Speaking of this, she suddenly thought of something.

"Wait..." Huiyuan held her chin and thought, "I remember now. A few years before my sister was killed, I remember she saved her travel photos on a floppy disk and sent me two or three floppy disks. I looked at them on the computer at the institute and immediately sent them back. After that, the floppy disk where I saved the drug information suddenly disappeared. I remember searching for it for a long time, but couldn't find it."

After listening to it, Conan naturally came up with an inference. "I see, it is very likely that the disk you sent back to your sister contained your drug information."

"Then we can go to where your sister lives and look for her." Dr. Agasa thought subconsciously.

"It's useless. The apartment my sister rented was vacated by the organization when she died, and all her belongings must have been disposed of." She changed the subject, "But she once said that it was a university professor who traveled with her who saved the photos on the disk. Maybe..."

Conan quickly responded: "Then do you know who this professor is?"

This concerns whether he can return to his original appearance, and Conan becomes extremely concerned about it.

"It's Professor Hirota Masami from Nanyang University."

Huiyuan Ai thought that this was one of the reasons why her sister changed her name to Hirota Masami. Her sister was kind to all her friends and was particularly sentimental.

"Hirota Masami..."

"But I don't know where he lives," said Huibara.

"Just ask Nanyang University." After Conan said that, the doctor answered. The only person who can get in touch with the other party here is him. Dr. Agasa picked up the phone and asked the service staff to help him find the phone number of Nanyang University. After a lot of twists and turns, he successfully asked for the number of Professor Hirota's home and successfully contacted him.

After learning the name of Miyano Akemi from Ai, Dr. Agasa pretended to be her friend and made an appointment to go to Professor Hirota's house to retrieve the disk "containing travel photos".

When Conan learned that Professor Hirota had a strange magnetic disk in his hand, he felt relieved: There is no doubt about it, it must be that one!

Professor Agasa hurriedly prepared the car without delay, while Conan called Xiaolan to report, using the excuse of "staying overnight at the professor's house".

Using "the game software is fun" as an excuse, Conan spoke in a childish voice. After explaining, he didn't give Xiaolan a chance to say more. He quickly hung up the phone and took a deep breath.

In Haibara Ai's eyes, this was just like a child who was enjoying himself so much that he didn't want to leave.

"You are quite good at pretending to be a child."

"Yeah, but..." Conan heard the sarcasm and shot back leisurely, "I'm still not as good as you at pretending to cry."

The two got on the Beetle driven by the doctor and rushed to Shizuoka. Conan sat in the front seat, side by side with the doctor. He took this opportunity to quietly remind Dr. Agasa: "Doctor, you must not be careless with her."

"Are you talking about Ai?" The doctor leaned close to Conan's face, afraid that Ai in the back seat might hear it.

"She didn't tell us her real name and age. Just now, when I asked her about the purpose of their organization, she pretended to be completely ignorant. Maybe everything she said just now was a lie she made up."

“Why can’t I feel it?”

Although Conan said this, he did not doubt Haibara Ai to that extent.

When he was at the printing factory, he happened to see a portrait that had many features that overlapped with Haibara Ai's. He guessed that maybe that was what Haibara Ai looked like originally. But why did those criminals act like they didn't know anything about the man in black? Conan felt that they were not pretending to be joking, and they really didn't know Gin and Vodka. However, there was another possibility, that they were related to other members of the organization.

Previously it was Tequila, now it’s Haibara, maybe there are more members of the organization active nearby.

In this way, Conan looked out the window and thought about the problem, while Huiyuan looked out the rear window in a daze, wondering who the man in black was that she saw on the river bank at that time, until the doctor followed the road signs to Professor Hirota's house. As soon as they entered the door, Professor Hirota's wife Toshiko came out to greet them, and she said that she had heard about Dr. Agasa.

"Please come in." Toshiko led them to Professor Hirota's room.

"Have all his guests gone?" asked Dr. Agasa.

"Ah, today there are several groups of my husband's students who are visiting him." As she spoke, she had already reached the door of the study. "Old man!" She knocked on the door, but there was no response. "It's strange, I don't know what he is doing in there," she tried to hold the door handle, "and he even locked the door."

Conan had a bad idea when faced with the abnormal situation. He jumped up, put his hands on the door frame, and touched the small glass window on it. However, no matter how hard he tried, Conan couldn't open it.

He shifted his gaze and looked inside the room with a horrified expression.

Professor Masami Hirota was crushed under the bookshelf, books were scattered all over the floor, and black bloodstains were floating on the ground.

"Is there a spare key here?" Conan asked Toshiko the first thing he asked after landing.

"We don't have a backup key."

"Dr. Agasa, please help me break this door open now!" Conan emphasized, "Hurry up!"

The two of them knocked on the door several times and finally managed to break it open. After entering the door, they could see the outline of the whole tragic scene. They could tell that Professor Hirota Masami was dead without even checking.

"Doctor, notify the police quickly!"

Conan's professional ethics have led him to investigate the situation at the scene.

When he saw the trophy-like decoration, he immediately concluded that Professor Hirota had died from a severe blow to the back of his head. However, if he had just fallen and hit it, the amount of bleeding would be too much. In addition, the layout of the room was a bit out of place.

What’s more crucial is that they had just gone to Professor Hirota to get the magnetic disk, and within just three hours, he passed away.

Given their current situation, it is unreasonable to regard this as an accident. When Conan thinks of someone who might do this, the figures of Gin and Vodka instantly appear in his mind. The two of them are like two lingering dark clouds, constantly affecting his thinking.

After a while, the police arrived.

The police officer is an old acquaintance to Conan.

Henggou comprehended.

Conan met him during a murder case that occurred at a festival. He is a relatively reliable police officer who is also willing to listen to advice.

As soon as Yokomizo came up, he asked the surveillance personnel to investigate the entire room, and soon came to the conclusion. "Although I'm not sure yet, the possibility of accidental death is very high." As soon as he finished speaking, the accompanying forensic doctor picked up the trophy decoration that caused the death: "Officer Yokomizo, it seems that the cause of death was caused by this decoration. He may have hit it when he fell."

"That's true." Yokomizo nodded.

"Did he fall down?" Dr. Agasa wondered.

"What happened is this," Yokomizo explained his reasoning. "The deceased Hirota Masami was probably trying to take something off the bookshelf, so he stepped on it, and the entire bookshelf fell down. A decoration on the bookshelf hit the back of his head, killing him."

"The best evidence is that all the locks on the door and the windows above this room are locked. As for the only key in this room, it is scattered around the room like these books." Officer Yokomizo turned over the books on the ground and found the key. "It's under this book."

The doctor also felt that his inference was reasonable.

At this time Conan came out: "He might have been murdered... although it certainly looks like an accident."

Officer Yokomizo was attracted by Conan's voice. The moment he saw Conan, he thought of his idol: "I remember you were Mr. Mori's..."

The doctor came out to help Conan smooth things over.

Conan remained unmoved and pointed at the phone that was buried under the books.

"Look at this phone. It's on the floor, right?"

The doctor tried to explain that the phone was originally placed on top of the bookshelf and fell down with it.

Conan denied the doctor's guess. "If that's the case, why didn't the microphone fall off? It's too unnatural. Although there is a book covering it, it's obvious that someone deliberately messed up the whole room."

Officer Yokomizo was intelligent and understood it immediately. This could not be a normal scene, but was deliberately created by the murderer. "So," he muttered, "this is a closed room murder case."

"Murder..." Toshiko said in horror.

"That's right." Yokomizo said to himself, "All the locks in the room are locked, and they were locked from inside."

"Who is it? Who killed my husband?" Toshiko burst into tears.

Officer Yokomizo comforted her and asked if there were any suspicious people among the visitors tonight.

"Including Mr. Agasa, it seems that four or five people came here tonight."

When Dr. Agasa heard that he was being mentioned, he immediately defended himself: "As for me, a friend of mine accidentally sent his disk to Professor Hirota by mistake. I just came here to get the disk back. I think the disk must be next to the computer."

He looked over and was so shocked that his beard almost fell off -

Huiyuan Ai was sitting in front of the computer, typing away at the keyboard. "All the data on the disk is gone." Huiyuan called up the computer's local storage, "It seems that all the data on the computer may have disappeared as well."

Yokomizo was also shocked: this little girl was much more familiar with computers than he was. He looked at Dr. Agasa and asked who Huibara was.

Dr. Agasa was sweating profusely. He touched the back of his head and explained that Xiao Ai was also his relative's child. Then, he lifted Xiao Ai up from her computer chair and explained, "Anyway, I have absolutely nothing to do with this case. There can't be a fool in the world who would bring a child to kill people, right? Haha!"

Officer Yokomizo affirmed his words, and then taught Haibara not to touch anything in this room, and asked the three of them to wait in the next room.

Seeing that the data was destroyed so thoroughly, Haibara Ai couldn't help but consider the possibility that it was done by the organization - it was clean and neat, without leaving any traces, which was indeed their style.

But is it really necessary to go to so much trouble to create a closed secret room?

Conan was thinking the same thing. He confirmed with Huibara: "Could it be that they did this?"

They, naturally, refer to the people from the Black Organization.

"It is indeed possible," Huihara Ai did not deny, "If the disk containing the drug information, the missing record, and the record I sent to my sister at that time are all left in the organization..."

"I see."

Conan understood.

"Now that you have escaped from the organization again, you are likely to come back here to retrieve the information. This should not be difficult for them to predict, right?"

"I think it's normal that someone from the organization sneaked in here to retrieve the information, but was discovered by Professor Hirota and killed him, right?"

Gin's rude impression remained in his mind, and Conan also felt that they would spend so much time to build such a secret room. "It's not certain yet." He said. We must listen to what the people who came here tonight say before we can draw a conclusion. After all, the words of so many people almost cover all the time that Professor Hirota took action at night, leaving too little time for the Black Organization to act.

……

Yokomizo learned from questioning Toshiko that a student named Hosoya had been there before, and the rest of the people were unclear. Just when he was about to have his subordinates conduct a thorough investigation, Conan sneaked in and activated his skill: "Oh, this is so strange! This phone seems to be glowing!" Seeing Yokomizo turn his head, he added: "This should be called an answering machine, right? If you listen to it, you might know something?"

"That's true."

Yokomizo turned his attention to the phone call. He already knew that the kid who followed Detective Mori had amazing observation skills, and he didn't show any displeasure. After checking the messages, there were thirteen in total. He asked Toshiko and learned that the callers, Shirakura and Morioka, were both students of Professor Hirota and were scheduled to visit tonight.

As Toshiko was explaining, a woman appeared behind the door.

"Um, what happened?" the woman asked.

Toshiko looked back, showing a helpless expression. "Amei, why are you here suddenly?" Seeing the student who used to have a good relationship with her and her husband, Toshiko couldn't help but burst into tears. "Teacher..." Seeing the miserable situation, "Miyano Akemi" comforted Toshiko and hugged her, "Teacher's wife, what is going on?"

In fact, the current Akemi Miyano is specially impersonated by Winnet.

The organization has started to recover information related to Shirley, including a disk that Shirley sent back to Miyano Akemi. According to the records, this disk is likely to contain information related to drugs and is an item that needs to be recovered.

The best method, other than robbing a house, is to come in person to retrieve the lost items.

Among all the people in the organization, she, who has the ability to disguise herself like Vermouth, is the best choice to carry out the mission.

Winnet had no intention of completing the mission, but then she thought about it and realized it was something related to Shirley.

Although she didn't think Shirley would risk her life to retrieve the disk, she couldn't rule out the possibility that she was being used by some force, such as some official organization. They were just trying to get information about the organization, and Shirley, an important core member, was like an intelligence box to them. If Shirley sought their help, she would definitely be able to exchange some intelligence.

Although such a series of speculations was a bit neurotic, she was indeed in such a state.

There is absolutely no trace of it.

All possible methods have been used.

Recruit temporary forces and look for her trace.

Install hidden cameras at the places where necessities are purchased.

Use hacker techniques to break into the surveillance system and retrieve a large amount of video footage.

Winnet stared at them day and night, her eyes were dazzled, but there was no information that seemed to be related to Shirley.

A suppressed despair spread in her heart, so that she was in a bad situation in all aspects, including her mood.

Encountering Professor Hirota being murdered was something that had deviated from her expectations.

"Who are you?" asked Officer Yokomizo.

"My name is Miyano, Akemi Miyano," Winnett replied, "I am a former student of Professor Hirota."

When Winnett said the word "Miyano Akemi", Huiyuan's face turned pale and she slowly hid behind Dr. Agasa. Her sixth sense told her that the woman pretending to be her sister was related to the organization.

There was a mixture of fear and excitement.

Huiyuan Ai realized that she was in a strange and contradictory state. Whether the person pretending to be her sister was Winnet, this conclusion would lead to the opposite direction of things.

Conan was also stunned.

He had seen Hirota Masami before, so he knew that the man in front of him looked exactly like Hirota Masami. Adding to what Huiyuan mentioned that "his sister was killed by the organization", he immediately thought of the 1 billion yen robbery. The person pretending to be Hirota Masami was Miyano Akemi, but...

He clearly remembered that Miyano Akemi had died in the fire.

This person couldn't be Miyano Akemi.

He immediately confirmed this after seeing Haibara Ai trembling slightly.

Even if he couldn't recognize her, as Miyano Akemi's biological sister, it was impossible for Haibara to be afraid of her biological sister.

"Habara, what on earth is going on?" Conan quietly approached Haibara Ai and glanced at her in confusion, "What on earth is going on? Was she sent by them?"

"I don't know... I don't know." Huibara's voice was small and trembling. "She is a member of the organization, absolutely. But, she is definitely not my sister."

In addition to her sensitivity to the smell of tissue, there was no way her sister would risk her life and appear here openly - Winette would never let her do that.

and many more……

if it is like this.

A guess formed in Haibara Ai's mind. Since "Miyano Akemi" had a "dead" symbol in the organization, the person pretending to be her sister must have been instructed by the organization. Whether it was Vermouth or anyone else, it was impossible for them to have a sufficient understanding of her sister -
