My brother is FBI, and I am a crazy wife protector.

That night, Xiao Ai thought that her sister had left a magnetic disk containing the drug information in the tissue that she had sent to her university professor Hirota Masaki.

Then the day after Xiaoai and Minghui confessed to Conan about the organization and their identities. Dr. A Li took Xiao Ai, the smaller Minghui and Conan to Miyano Akemi's university professor Hirota Masaki.

But Minghui, who knew the plot, certainly knew that Professor Hirota Masaki would die, so he was wondering whether he should go to Professor Hirota in advance to get the magnetic disk. As far as he is concerned, it may not be a big problem, but he is a child now and has taken the medicine, but the antidote has not yet been developed. Even if there is information on medicine, it takes time

"By the way, Xiao Ai, the magnetic disk of that medicine should be encrypted, right?"

"Um………The general situation is like this. It is impossible for organizations to put drug information there so that others can easily see the contents."

"So if the police can't decrypt the magnetic disk, as long as you don't open the magnetic disk casually with an ordinary computer, it will be fine."

""Because I suspect that there may be another step in the encryption done by the organization, that is, once it is opened by someone other than a designated computer, the data will be automatically destroyed. Don’t forget that I also spent some time in the organization. It is impossible for them to have only one encryption measure"

"Does that mean that even if we get the drug information, we can't open it on the doctor's computer?"Conan asked next to him

"Yes, this may cause all the information to be deleted or cause Dr. Agasa's family to be noticed by people from the organization. After all, no one knows whether that information is monitored by the organization."

"But in this case, maybe that information is no longer useful to us. Because even if we get the information, if we don't have access to the designated computer, the medicine information will still be invisible."This sentence was said by Conan after thinking about it.

"Maybe so. So do we still need to visit Professor Hirota to get the information back?"Xiao Ai asked Minghui next to him.

"I think it's better to get it back. We can't let such important information wander outside. After all, it is about that organization, and it would not be good if it had some other impact after being obtained by members of the organization or others. This information may be used in the future."Minghui said.

Because Xiao Ai told Miyano Akemi in advance that she was her sister, and Conan doesn't know that Mingmei is still alive. In addition, Minghui was watching and said a few words to Conan, so he didn't say anything to Conan. Xiao Ai loses his temper, even though he may feel uncomfortable, but thinking about the death of Miyano Akemi, Hirota Masami, he still feels more guilty. Of course, he also knows that he needs Xiao Ai, the inventor of the drug, if he wants to change back. Help.

The next day, Dr. Agasa and the others went to Professor Hirota Masaki's home, but no one opened the door when they knocked. Then when they broke the door and went in, they found that Professor Hirota was dead. And the door was locked. , that is to say, if it is not suicide, it is a secret room murder case

"It seems that the scene is very clear, the secret room murder incident"

"You're not a detective, so since when did you like to do some detective work?"

"Xiao Ai, I don't like to do detective work. I just provide ideas to a certain detective. Let's forget about solving the case. I'm not interested."Minghui and Xiao Ai were chatting outside the scene.

Dr. Ali asked Professor Hirota's wife to call the police immediately. After a while, Officer Henggou came to the scene. He saw the scene and was about to close the case as an accident. Conan While still investigating the scene, classmate Minghui outside the door alerted Officer Henggou

"The room was so messy, and the phone was covered under a book, but the receiver didn't fall off, which meant someone might have messed up the room on purpose."He said this based on what he knew about the plot. Of course, he also went into the room and took a look.

After all, if he didn't even take a look at the scene and said it was a secret room murder, Officer Henggou wouldn't believe it at all. He It's not Conan. He doesn't live in Uncle Mori's detective agency.

"It seems to be a locked room murder case, but what about the secret room method?"Conan came out after surveying the scene and asked Minghui

"I don’t know this yet." In fact, Minghui knew, but he didn’t want to be too pushy, and he was not a detective.

According to the phone message, Officer Henggou asked Shirakura Yo, Michio Morioka, Hosaya and Hiroshi who came to see Professor Hirota today. Three people were brought here. Just at this time, Shirakura Yang came here by himself. He seemed to have just learned that Professor Hirota had been killed.

But the ten messages on the phone at the scene made Conan feel strange. And Conan was originally trying to decipher the murderer's secret. The modus operandi, but Minghui felt that it was better to end the matter quickly and get back the hard drive with drug A information, otherwise who knows what might happen.

"Dr. Agasa, I think the murderer should be the man named Shirakura Yang."

"I said, Conan, if you still don’t know who the murderer is, would you like to lend me the bow? I already know the murderer’s modus operandi."No way, this secret room murder case is actually quite simple, but Conan seems to have not found the key point, so he can only deduce the truth by himself.

After Conan handed the bow to Minghui, he hid behind Dr. Ali and prepared Starting to reason, of course before starting, he had asked a police officer to help him buy a tape of the same type as the one in the answering machine.

"I already know the murderer's methods, and of course I also know who the murderer is. Pull out the tape from the tape to a certain length, walk outside the door and put the key on the tape. Go back to the notebook in front of the phone in the room, place the three chess pieces upside down in a triangle, and hang one end of the tape right inside, close to the phone. Then put the notebook on the three chess pieces, go out and lock the door, then use the mobile phone to call the phone in the house. The strap shrinks and drives the key. When the chess piece is knocked down, it is pressed underneath, and the strap outside is also Rolled up, this completes a secret room"

"The one who has the ability to kill people with this method, Mr. Shirakura, who left a message on the phone, is you."

"This method, there is no one else but you, it is better to admit it as early as possible."Police Officer Henggou also said to the suspect

"If I'm not wrong, you came back here this time to get back the tape on the phone that has your fingerprints on it, right? Because it was a sudden murder, you were unprepared and got your fingerprints on the tape. What, is there anything else you want to say?"

"Yes, I killed the person. Those things were in my car parked outside the door."In the end, the prisoner confessed like this.

The matter was over, but the drug information that was supposed to be retrieved could only be retrieved a week later because the police needed to investigate. One day a week later, after getting the drug information, Xiao Ai was She was about to open the organization's encryption lock on Dr. A Li's computer. But she remembered what Minghui said if it wasn't a specific computer, all the data would be automatically destroyed. Then she stored this with Drug A The hard drive of the data is placed under the bed in Dr. A Li's room.
