Conan wants to lie down but won't let him

"Hey, Huiyuan, that voice seems to be..."

"Yes, although he deliberately changed his tone and pitch, it should be the voice of Vodka." Haibara Ai gave a positive answer directly.

"It's him!" Conan was surprised! Then he thought of something.

Conan felt even more anxious. No, he had to speed up the process, otherwise if he was targeted by Vodka and others, the situation would be bad.

At this time, Officer Yokomizo had conducted a detailed analysis of the situation at the scene and found that the only key was pressed under the notebook.

In addition, there was a collapsed bookshelf, a fatal wound on the back of the deceased's head, bloodstains on the trophy, and a completely sealed room.

Officer Yokomizo concluded that it was an accident: Professor Hirota was taking something from the bookshelf when the bookshelf collapsed, and then Professor Hirota, who was crushed, hit the back of his head against the trophy, causing the tragedy!

Conan kept staring at the answering machine. He instinctively felt that so many phone recordings were the key to solving the case.

The key to this case is to crack the impossible locked room murder method.

Just as Conan was thinking hard, Haibara Ai came up and said that it was useless and that there was no way to crack the secret room. It must be an accident.

We can return to Tokyo now. It would be dangerous to stay here any longer. No one knows when Vodka and Gin will appear nearby.

So Haibara Ai placed the white horse on a chess piece in front of Conan and said to Conan, "Checkmate, there is no way out!"

Then Haibara Ai was about to call Dr. Agasa to leave through the back door. At this moment, Conan, who was looking at the reflection in his glasses, stopped her! Conan understood again!

So Conan asked Dr. Agasa to help him perform a double act. Dr. Agasa was responsible for lip syncing in the front, and Conan used the bow tie voice changer to adjust to Dr. Agasa's voice to make inferences in the back.

The murderer was Mr. Shirakura, who had left more than 10 messages on the answering machine. Mr. Shirakura must have acted on impulse and accidentally killed Professor Hirota.

In order to cover up the fact that he accidentally killed someone, he came up with this method on the spur of the moment.

First, pull out the tape from the answering machine, then thread the keychain onto the tape, and then pull the other end back into the room. Place three chess pieces under the notebook as support.

Because the chassis of the chess set is extremely stable, the pulling force of the answering machine alone is not enough to pull down the upright chess piece, so the chess piece must be placed upside down so that when the key passes by, it can pull down the chess piece and press the key underneath.

As more and more recordings are made, the tape will slowly return to the answering machine's tape. In order to verify the feasibility of this method, Conan demonstrated it on the spot.

After using this set of techniques, everyone was stunned, especially Haibara Ai. As a person with high IQ since childhood, she thought that she would not be able to crack it after watching the scene. However, Conan slapped her in the face and cracked it.

During the previous counterfeit money case, she thought Kudo Shinichi was nothing special, and she had also deduced those situations. However, she thought this time the secret room had no solution, but Conan solved it.

After Conan finished the demonstration, he returned to Dr. Agasa and pointed out the murderer directly.

"Officer Yokomizo, the only person capable of this technique is Mr. Shirakura Yo, who left over ten messages on his answering machine."

"But even if this method is theoretically feasible, it can't prove that I am the murderer!" Bai Cangyang panicked when he saw that his method was cracked.

Now that he has been directly accused of being the murderer, he jumped out to defend himself even more eagerly, emphasizing that reasoning cannot be used as evidence.

"No, you definitely killed Professor Hirota on impulse tonight, so you had no preparation. You can't explain your fingerprints on the tape. The entire disk is covered with your fingerprints!

It's hard for you, you came up with such a brilliant trick in a panic, but unfortunately the fingerprints on it prove that you are the murderer, and there is no room for you to explain yourself."

Conan delivered a fatal blow using Dr. Agasa's voice.

At this point, Shirakura Yo knelt down, admitted his crime, explained why he accidentally killed Professor Hirota, and was then taken away by Officer Yokomizo.

Just after the incident was resolved and Dr. Agasa and Inspector Yokomizo said goodbye, Conan summoned Haibara Ai to go home, but found that Haibara Ai was standing there in a daze, unmoved.

"Why? Why didn't you save my sister at that time?" Haibara Ai, who was already in tears, asked Conan.

"Your sister?" Conan was also stunned and confused. Conan said he didn't know her sister, Miyano Akemi.

"Don't you understand yet? Hirota Masami is a pseudonym given by Professor Hirota to my sister." Haibara Ai could no longer stop her tears.

"Could it be that! The 1 billion yen robber Hirota Masami is..." Conan's thoughts suddenly fell back into those painful memories. He watched Hirota Masami die in front of him, helpless.

"So...she is your sister!" Conan's tone also became gloomy.

"That's right! I'm asking you now, since you have such good reasoning ability, you should be able to see through my sister's matter easily. But...but you...why didn't you..." Haibara Ai grabbed Conan tightly, her voice completely choked, and no one could hear what she said afterwards.

Haibara Ai cried so hard that she burst into tears and cried until she was hoarse, which reminded Conan of the thing he had forgotten. This was also the first time that Haibara Ai revealed her true feelings to Conan.

Just when Haibara was feeling sad and Conan was regretting not telling the police his reasoning ideas as soon as possible, which led to the tragedy, Conan suddenly caught a glimpse of inspiration.

"Hey! Haibara!! Stop crying! If the voice in that message just now was Vodka's, then it means the organization has just investigated Professor Hirota and hasn't paid him a visit yet! So..."

"You mean..." When Haibara Ai heard Conan say this, her hope was rekindled.

"Are you saying my sister might still be alive? But didn't she die right in front of you? It was all reported in the newspapers. Could she really still be alive?"

Haibara Ai doesn't want her hopes to be dashed again and she doesn't want to be disappointed again!

"That's right! I always thought she died in front of me, but I was too sad at the time and didn't check Sister Yamei's breathing or heartbeat.

In addition, something else happened at that time that was not reported in the newspapers and was secretly blocked by the police.

It was when I was immersed in sadness that someone attacked me from behind and knocked me unconscious. I was careless and thought that the other party was afraid that the police would come soon, so he only took away your sister's body and did not kill me.

Now it seems that your sister was not taken away by the Black Organization, but was rescued by someone else. It is very likely that she is not dead, and she also came to visit Professor Hirota and took away the disk!

I wonder which force is rescuing your sister? What confidence do they have in dealing with the Black Organization? And why are they so confident that they can rescue your sister?

While analyzing, Conan raised questions about the suspense left behind.

"Could it be..." Haibara Ai seemed to have thought of something and said with her eyes wide open.

"Hey~ Haibara! Do you know something?" Conan asked hurriedly.

"No! Not really. My sister used to have a boyfriend who was an undercover agent from the FBI. He approached my sister just for the mission, to be able to go undercover in the organization.

As a result, the capture of Gin failed, and Gin escaped. The situation of my sister, who introduced me, can be imagined. If I hadn't protected my sister, she might have been killed by the organization long ago.

Since the undercover operation failed, that guy has never contacted my sister again. So I didn't think about this ruthless guy at first.

If there are no other imaginable groups, then the FBI agency that guy belongs to has the power to do these things."

Haibara Ai directly told what she knew.

"Hmm! This is indeed possible. At least it's a direction, which is better than nothing!

So hold on to hope. Maybe your sister is still alive, but it's inconvenient for her to show up. She probably doesn't know that you've defected from the organization or even become smaller! "

Conan expressed his own opinion and comforted Haibara Ai. Haibara Ai had always pretended to cry before, but this time she really cried, and Conan felt that he could not bear it.

"In short, let's tell Mrs. Hirota that no matter who comes here next time, they must never mention that your sister has been here." Conan said after thinking for a while.

Next, before leaving, Dr. Agasa and his colleagues had a special conversation with Mrs. Hirota, and Mrs. Hirota was very sure that it was Akemi herself who came that day.

Because there are many details of life that only the parties involved know clearly, and Professor Hirota and Mingmei had a very happy chat at the time, which lasted for two and a half hours.

This further gave Haibara Ai confidence, thinking that her sister Miyano Akemi was still alive. Before leaving, Dr. Agasa repeatedly reminded Mrs. Hirota that no matter who came, she must not reveal the information that Akemi had recently visited.

Dr. Agasa and Mrs. Hirota said that Mingmei had encountered some situations recently and some bad guys were looking for her. If Mrs. Hirota said that she had seen Mingmei, that group of bad guys would do something bad to her, so she must not say that she had seen Mingmei.

Mrs. Hirota said that she understood that her husband was murdered. She was also afraid that she would get involved in unnecessary trouble. Moreover, Dr. Agasa was in front of her to help her deduce and find the murderer of her husband. She had no reason not to trust Dr. Agasa.

The matter finally came to an end, and everyone set off to return to Tokyo.

In the next few days, after a brief period of calm, Haibara Ai integrated into the life of an elementary school student while waiting for news from her sister.

Until one day, a phone call came to Dr. Agasa's house. The caller was Fujiwara Hiroshi, who was using a voice changer and was of course looking for Miyano Shiho.

That day, Fujiwara Hiroshi guessed that Miyano Shiho had turned into Haibara Ai, and the members sent out to follow her also came back to report the situation. They waited until Conan stopped staring at Haibara Ai before taking action.

This day, why did we have to wait until this day? It was because Conan went out with Kogoro Mouri, so this opportunity just happened to come.

"Hello! Is this Haibara Ai's home?" Fujiwara Hiroshi asked using a voice changer.

Fujiwara Hiroshi was also unsure whether it was Dr. Agasa or Ai Haibara who answered the call, so he asked the higher-ups first.

"It's me!" Haibara Ai's voice came out, "Excuse me, where are you from? What can I do for you?"

Fujiwara Hiroshi thought to himself, what luck! This way he didn't even have to pretend to be a teacher from Teitan Elementary School for a home visit.

Fujiwara Hiroshi's original plan was that if Professor Agasa answered the call, he would replace it with Haibara Ai, using the excuse that a teacher from Teitan Elementary School was visiting a new student's home.

Now I answer the phone directly, so even this step can be omitted. I can get straight to the point and get straight to the point.

"Oh! So it was you who answered the phone! Haha, that's just right, I'm looking for you, Miyano Shiho!" Fujiwara Hiroshi's voice came from the other end of the phone.

"Who are you? What do you want to do?" Haibara Ai was horrified because she and Conan had also told her the code name Shirley, and no one would know her real name.

The other party called out her name directly, so there was no need for her to deny it and she directly asked the other party's purpose.

"It seems you don't intend to deny it. Let's get down to business. Your sister asked me to find you. Now that I've found you, I'm ready to come pick you up so you sisters can be reunited!

Now, don't alarm Dr. Agasa at home. Find a reason to go out to the street intersection. There is a black car parked there. Get in the car and it will take you to the meeting place!"

Fujiwara Hiroshi directly stated his purpose and pointed out that he was very familiar with the situation on her side and knew that there were only her and Dr. Agasa in the room.

"Okay, I understand! I hope what you said is true!" Haibara Ai's brain was spinning rapidly at this time, analyzing the truthfulness of what the other party said.

"Of course! Based on my understanding of your investigation, if it was someone from the Black Organization, they wouldn't have needed to make this call. They would have just rushed into your house and arrested you! So don't waste time, get out of here!"

Fujiwara Hiroshi bluntly pointed out that he had no hostility and that even if he had the ability to arrest people directly, he would not do so, which was a manifestation of his goodwill.

After hanging up the phone, Haibara Ai thought about it for a moment and felt that it did make sense, so she found an excuse to go out to the library to look for information. She didn't come back for lunch and just went out.

They arrived at the intersection and got into the car arranged by Fujiwara Hiroshi. After getting in the car, Ryuichi covered Haibara Ai's eyes with a black cloth, indicating that the place they were going was confidential.

This was also arranged by Fujiwara Hiroshi, so as not to expose the secrets of Yueying Island. Soon, the curtains were drawn on the windows of the black business car, and the business car drove directly onto the cruise ship deck until it arrived at the Yueying Island base camp.

At this time, Miyano Akemi had been waiting here for a long time, waiting for Miyano Shiho to arrive.

"Okay, we're here!" Long Yi said as he untied the black cloth covering Haibara Ai's eyes.

After regaining her sight and briefly adapting, Haibara Ai got out of the business car.

"Shiho!" Miyano Akemi saw Haibara Ai getting off the car and becoming smaller. Although she was surprised, she recognized her sister at a glance.

"Sister! You are really still alive, sister!!" Haibara Ai really saw her living sister, and her voice was directly crying.
