My neighbor's name is Conan

Thanks to Kudo Yusaku being a well-known writer of mystery novels, book fans often send fan letters to the Kudo Shinichi family, and many diehard fans before Kudo Shinichi also send letters to the Kudo Shinichi family.

Therefore, even if the organization in black is monitoring the mailbox of Kudo Shin's family, if Aoki Matsu adds another letter to it, it will not arouse the other party's suspicion.

What's more, by this time, Miyano Yasushi should have made changes to the death list, and the black organization will not continue to investigate whether Kudo Shinichi is dead or not for the time being.

At this time, even if Gin and Vodka didn't catch the mole and fake wine, they should still be keeping an eye on Miyano Akemi. Therefore, it is a very safe time to send the second letter to Conan at this time.

Just do it.

Aoki Song carefully held the envelope, took advantage of the lunch break, drove to the edge of the city, and stuffed the envelope with Osaka's special stamps directly into a mailbox. He would have work in a few hours. The personnel come to collect the letters in a unified manner, and then divide the letters into regions and deliver the letters one by one to the sender's address.

In the second letter, Aokimatsu didn't reveal anything more. He just told Conan that if they don't contact Miyano Akemi, there will be no way for Miyano Shiho to copy a complete APTX4869 through Miyano Akemi before escaping from the black organization. Drug information.

As for the time and operation, whether it will be successful or not, Aoki Song doesn't know.

However, he feels that there is a high probability of encountering a "drama kill", and it is impossible for Conan to obtain the complete "APTX4869 drug" information so easily.

This can be regarded as an experiment by Aoki Song to see if Conan, as the protagonist, can't be invincible in the plot. If he can, then Conan is truly invincible.

If not, then everything is back to the way it was in the cartoon, nothing has changed.Qing Musong has nothing to lose, anyway, the little white mouse is not him.

After sending the letter, Aoki Song was very relaxed, and didn't care about Conan's reaction after receiving the letter.

Anyway, he had been hiding in the dark, and there was no way Conan could take off his vest. Aoki Song would not expose Conan's true identity foolishly. In this case, Conan would try his best to hide his true identity in front of Aoki Song.

Three layers of buff.

Totally stress-free.

I just don't know if Conan will stop for a few days after receiving the letter.

Facts have proved - no!

Early the next morning, the Metropolitan Police Department received a report from Mao Lilan. Needless to say, Aoki Song rushed to the scene with Takagi Wataru and others.

The scene is small, but it is a bit shocking.

Because the workload was really heavy - the areas where the bathroom door, windows and walls were connected were covered with dense tape, and three big words "Farewell" were also taped on the glass door.

The first time he saw this scene, Aoki Song recalled this case in his mind.

There's no way this case is too classic.

Aoki Song also learned something from this case - do not use two different acid-base cleaners at the same time, because the mixture of two different acid-base cleaners will produce poisonous gas. If used in a closed room, it will cause poisoning. die.

From then on, Qing Musong bought these things by herself and only bought one brand.

He doesn't know much about acid and alkali, and he's not interested in checking them online one by one, and even if he checks them, the rhetoric on the Internet may not be correct.However, there should be no problem in mixing products under one brand.

As usual, Aoki Song asked Takagi Wataru to understand the basic situation of the deceased, and he walked into the bathroom to inspect the scene after the forensic department took photos of various places at the scene.

At a glance, there are three strange places in this scene.

First, the deceased cut his wrists to death, but there were many scars on his wrists. Judging from these injuries, the deceased cut his wrist multiple times, and the cuts were not done in one location, but moved slightly as he was cutting.

When a person commits suicide and chooses to slit his wrist, it is indeed impossible to be as precise as a machine, and he will hit the same spot every time. But people who really want to commit suicide will subconsciously try to cut in one position in order to enlarge the wound and bleed more.

As for the deceased, not only were there multiple scars on his wrist, but they were also in different directions. They looked like they were drawing an "x". There were several cuts on the left and several on the right. The area was as wide as a knuckle, which was not normal.

Aoki Song remembers that when he took this class in the police academy, he said that no matter whether it was a person who wanted to die or someone who was hesitant, if he chose to slit his wrist, the wounds would almost be parallel when he took the initiative and was not threatened. Wounds, not such cross wounds.

Even if there is a slight angle error, it is impossible for the angle between the two scars to reach 90 degrees.

Would someone really slit their wrists like that when committing suicide?

Second, the blood on the edge of the bathtub.

On the surface, after cutting his wrist, the deceased put his hand in a bathtub filled with water and pressed the heat preservation button in order to keep the wound on his wrist bleeding and let himself bleed to death.

This method of suicide is not strange, but what is strange is that there are still blood spatters on the inner wall of the bathtub, but there are no blood stains on the wall of the bathtub. Some of the blood stains are obviously wrong.

It looked like someone had wiped away the blood stains on the bathtub wall. Of course, it was also possible that there was something on it at the time, but it was gone now.

In other words, this case is definitely not a suicide, but a homicide.

Of course, as Aoki Song, who has recalled the case, he not only knows who the murderer of this case is, but also knows where the evidence is.

It's just that you can't just identify the murderer all at once, otherwise you won't be able to arouse others' suspicion.

The process to go still has to go.

The third strange place was not the two bottles of cleaning fluid poured on the floor, but the bathroom door.

Others don't know what fighting power Mori Kogoro and Mori Ran are, so how could Aoki Song not know.

There is also a sister of the deceased. The bathroom door is a transparent glass door. Although I don't know the quality, it is definitely not as good as the all-wooden door.

Even if it is fixed with tape, under the impact of Maori and his daughter, the door is not only not hit or damaged, but also the corners of the door frame are not deformed, and the connection with the wall is not loosened due to the huge force. The quality is really good. .

Is there really such a door?

All metal anti-theft doors are not of such good quality!

Aoki Matsu still trusts Mori Kogoro and Mori Ran's force value very much.

Not to mention that he recalled the case, even if he didn't and without Conan as a guiding light, Aoki Song could still assert that this was definitely not suicide.

After Aoki Song finished examining the crime scene, Takagi Wataru came over and reported, "The police department, the deceased's name is Aoshima Mina, and she is 24 years old. The person who discovered the deceased's death was the deceased's sister, Miss Aoshima Zendai."

A forensic criminal who followed Aoki Song out of the crime scene continued: "The cause of death of the deceased was a stab wound on his left wrist, accompanied by blood loss caused by a ruptured artery.

In addition, we also found hydrochloric acid and acidic bathroom cleaners in the corner of the bathroom. However, after testing, it was found that although the outer packaging of the detergents is different, they are actually a kind of detergent and will not produce poisonous gas after mixing. "

At this time, the "big clever" Mori Kogoro on the side couldn't help but said: "Could it be that Ms. Mei Cai originally wanted to use the poisonous gas produced by the mixture of two different cleaning agents to commit suicide, but after sealing the bathroom, she found that the two The bottle of cleaner was the same, so this one was changed to suicide by slitting the wrist."

Qing Musong shook his head, and then said firmly: "This is not suicide, this is homicide."

"This, how is this possible!" Mori Kogoro was shocked.

Conan's eyes lit up when he heard the words, he had already noticed the blood stains on the bathtub wall.

How could a person who wanted to commit suicide still have the heart to wipe the bathtub after cutting his wrists?

If there was something covering it, why didn't they find it after they broke into the bathroom.

There is only one situation that can explain all this - that is, the deceased was killed by him, the blood stains may be wiped by the murderer accidentally, or maybe the things placed there were taken away by the murderer.

[Sure enough, Brother Qingmu's judgment is also homicide. 】

Aoki Song's judgment also made Conan more convinced that this case was a homicide and not a suicide!

"Police Department, we found an invoice in the living room. Judging from the items purchased on it, it should be the origin of the two bottles of detergent in the bathroom." A criminal came over and said with an evidence bag.

Qing Musong took a look at it, and then said: "You go to this convenience store to confirm this and see who bought these things. It is best to have a certificate or monitor."

"Yes, I'll go right away." The other party replied.

At this time, the criminal from the forensics department also reported: "Police, we have checked the tape on the door, and there is only one fingerprint on it, which should belong to Miss Qingdao Meicai."

"I see."

Qingmusong was not surprised by this, and even if there were Qingdao Quandai's fingerprints on it, the two sisters lived together, and the other party had an explanation.

Another criminal came over at this time to report that they found traces of tape on the edge of the coffee table in the living room.

"Miss Quandai, can you explain why the tea table in the living room is surrounded by tape marks?" Qing Musong asked Qingdao Quandai.

Qingdao Quandai was a little nervous when he heard this. After all, the police officer in front of him insisted that this was a homicide, not a suicide. Qingdao Quandai was a little flustered, but he still said bravely: "I'm moving out soon, and I'm packing up my belongings." When packing things, I need to use tape, so Meicai helped me tear it up and stick it around the coffee table."

The whole generation of Qingdao also thought about lying, but she was not the only one who knew about it. If that person heard the news, he would probably rush over immediately.

Once her lies were exposed, the police would be more suspicious of her. It would be hard to tell the truth now and reduce their suspicions.

Sure enough, after Qingdao Quandai said it, she saw that the police officer stopped asking her questions for the time being, and seemed to have believed this reason.

After waiting for a while, the two criminals who went to the convenience store came back.

Aoki Song immediately asked: "How is it? Have you heard any news?"

One of the criminals took out a small notebook and reported to Aoki Songhui: "Police Department, we got some information. At about [-]:[-] last night, the convenience store did sell two bottles of detergent and tape. In addition, this lady also bought two cans of canned beer.”

Hearing this, Maori Kogoro said quickly: "I just saw two empty beer cans in the kitchen, and there were some sleeping pills."

After finishing speaking, Mori Kogoro said with a serious face: "Take sleeping pills and drink alcohol, I think Miss Mina's mind will definitely not be clear by then, if someone at this time..."

If someone makes trouble, it is not impossible for Miss Mei Cai to "suicide".

Aoki Song thought for a while and asked: "Did they notice anything strange at that time?"

"They said that Ms. Meina looked the same as usual, but that she suddenly changed one of the bottles of detergent she purchased to another one when paying."

"That's it! This shows that the deceased did not understand the principle, but did it on purpose. In this way, the case of homicide is even greater." Aoki Song said, and then he was slightly stunned as if he was pretending to see it accidentally. He looked behind the criminal who just reported to him - that is, at the door of the entire house.

"Is this bloodstain?" Qing Musong pretended to be hesitant, and then immediately called the forensics department's criminal photo inspection, and compared it with the bloodstain of the deceased.

Before the criminals in the forensic class were collected, the door suddenly opened, and a man wearing a mask rushed in panting, and shouted loudly: "Meicai!"

At this time, Qingdao Quandai who was staying in the living room heard the sound and came out. He looked at the person and shouted: "Xianji."

This man named Xian Er, after seeing the whole generation of Qingdao, had a look of disbelief, and immediately asked loudly: "Meicai, I heard that Mei Cai committed suicide! Is it true?"

"Hey!" Qingdao Quandai answered with his head down, and then asked: "But Xianer, how did you know about this?"

Mr. Xian'er heard the words and immediately coughed, coughing like a heart-piercing cough, as if he wanted to cough up his heart.

At this time, Takagi Wataru on the side said: "We informed this gentleman, because when we estimated the time of death of the deceased, the phone here happened to record this gentleman's phone message, and then we asked him to come over to assist in the investigation. case."

Mr. Kenji was immersed in unparalleled sorrow at this moment. After confirming the news of Qingdao Mina's death, he became extremely painful. He regretted and blamed himself and said to himself: "Why, why would Mina think Want to commit suicide? If I had known that time, I should have found a way to break the window and rush into the house!"

Upon hearing this, Aoki Song immediately asked: "Mr. Kenji, may I ask, when did you mean 'that time'?"
