My neighbor's name is Conan

If you just want to prove that the victim Zou Tianzhen has a mental problem, it is actually understandable to draw red lines on the wall.

But there is no need to carefully apply crayon on the edges of the beams and the key handle of the door. This will completely waste time and increase the risk of exposure.

Existence is reasonable.

If the murderer took the time to do this, there must be a reason.

In addition, there is another difficulty in this case: what method the murderer used to leave the key in the water.

Aoki Song had a hunch that as long as these two problems could be solved, the case could be solved easily.

Just when Aoki Song was thinking hard, Mouri Kogoro suddenly interrupted his train of thought with his confident words, "I know! Aoki Police Department, I have figured out the truth of the case."

What?

Aoki Song looked at him subconsciously, but felt a little unbelievable in his heart.

In ordinary cases, the "Mouri Exclusion Method" can be determined as Ke Xue. Mouri Kogoro can soberly solve the case on his own initiative without involving his family, unless it is a particularly simple proof question.

But it was obvious that Mouri Kogoro didn't know what Aoki Song was complaining about him in his heart. Instead, he looked at everyone very seriously and said, "I take back what I just said. This is a homicide case. Now please come with me."

Hearing what Mouri Kogoro said, everyone looked at each other and followed him.

Mouri Kogoro led everyone to the door of the house.

Then he said confidently: "What's the key to unlocking this technique? It lies in this email box."

Then Mouri Kogoro pointed to the mailbox next to the door, and then said: "The murderer first pulled the rope on the bridge of the architectural model to the gate. After passing through the mailbox, he walked outside the house and locked the door. superior."

Then put the key on a rope. As long as you keep pulling on the other side of the rope, the key will slide to the room.When passing the model bridge, the toilet paper will break and the key will fall into the water. "

"How's it going? Let's solve the mystery now." Mouri Kogoro looked at everyone present with a smile on his face.

"This method is definitely impossible to succeed." Aoki Song directly denied Mouri Kogoro's reasoning.

Before Mouri Kogoro could ask, Aoki Song said directly: "There is a right angle between the door and the living room. If you pull the rope from outside the door, it will rub against the pillar in that corner. Not only will it leave marks on it, And because of the right angle, it is impossible for the key to pass through the right angle and enter the living room.”

Hearing what Aoki Song said, Mouri Kogoro froze on the spot and blinked.

Then he immediately walked to the pillar in the corner and checked it out.

"Huh? How come there are no traces?" Mouri Kogoro asked doubtfully.

[It seems that the murderer deliberately painted the edge of the pillar with crayon so that people would not be able to see that he had used the rope. 】At this time, Conan standing aside looked at this scene and thought in his heart.

After one plan failed, another plan failed. Mouri Kogoro said confidently in the next second: "That's right! I understand. The murderer manipulated the toilet paper on the key directly from the mailbox."

Turning around, Mouri Kogoro's originally passionate voice weakened again, and he said weakly: "But, there are no traces left."

"Ah, this... is weird." Mouri Kogoro fell into confusion.

After looking up and seeing the skylight, Mouri Kogoro was inspired again: "That's right! Use the skylight!"

"Actually, the murderer's method was accomplished by using this skylight." Mouri Kogoro said excitedly, pointing to the skylight.

After everyone heard what Mouri Kogoro said, they all walked over and took a look.

Ayumi Maruta thought for a while and said: "If we look at the principles of physics, it is possible."

"Wrong, it's impossible." At this time, Mitsue Munada suddenly spoke, rejecting this view of Kogoro Mori and Ayumi Maruta.

Mitsue Munada walked to the window, pointed to a dog lying under the street lamp not far away, and said: "Look, there is a dog in the yard of the house opposite. This dog is particularly dedicated. In addition to its family, No one can get close to it."

After saying that, he looked at Hirohiko Kido standing behind him and said, "You said that, right! Kido."

After hearing the call, Hirohiko Kido immediately nodded and said, "Yes, Aunt Mitsue is right, this dog often barks at me."

"It's clear from where the dog is looking up. If someone is behaving strangely down there, it will definitely yell and make the noisy person restless." Mitsue Munada said why she thought it was impossible.

"In this case, it's impossible." Mouri Kogoro said a little disappointed.

Aoki Song looked outside the window at the dog lying under the electric light. The dog was in a really good position.

But unlike Mouri Kogoro's idea, Aoki Song thought that since the skylight was open, there must be something wrong.

The more impossible something seems, the more likely it is that the criminal used some incredible means to do it in the case of Ke Xue World.

There is only science and science in this world, and there is no weirdness.

But there is a dog outside, what happened?

Aoki Song thought for a moment and looked at Mitsue Muneda who was standing aside, and asked, "Mrs. Muneda, can I go up to the top of the building?"

Munada Mitsue was stunned when he heard this, and then understood what Aoki Song meant, but he shook his head, "We keep the roof locked all the time. Only the administrator and I have the keys. No one should be able to go up, and this is the top floor of our apartment." There’s a roof over it.”

There was no way someone could have slipped the key down the line from the roof into the model.

To be cautious, Qingmusong still asked someone to check it out.

Facts have proved that the door to the top of the building was locked tightly, and there was no sign of the lock being picked.

Aoki Song was thinking about the modus operandi of this case, and Conan was doing the same at the moment.

Firstly, it was for the justice in his heart, and secondly, it was also because Conan suddenly discovered that Aoki Song was not as "godly" as before. He did not immediately solve the case after searching the scene as before.

This aroused Conan's competitive spirit.

But now it's not the competitiveness that wants to defeat Qingmusong, but... the competitiveness against the murderer.

The more difficult the case, the more excited Conan becomes. Plus there is Aoki Song next to him, and Conan is really excited at this moment.

[First of all, this is definitely a homicide, and the murderer is most likely Kido Hirohiko. 】

[The victim only had a wound on his hand, and without any hesitation, he cut off the artery with one knife.The only people who can do this are people with a medical background.But what method did he use? 】

Conan looked solemnly at Kido Hirohiko, who seemed to be very sad because of the death of his friend, and then looked around, trying to find some clues.

Suddenly Conan's eyes were on the street lamp outside the window.

The bright street lamp is surrounded by many flying insects. This is a mosquito catching lamp.

[Wait a minute...the top of the door, and the crayons all over the wall, and then the open door and skylight...] Conan suddenly had a flash of inspiration, then his eyes lit up, and he looked towards the skylight [I understand!No wonder he wants to open that skylight a little!Create a seemingly imperfect secret room! 】

Conan had already simulated the murderer's method of committing the crime in his mind, but with Aoki Song at the side, Conan seemed to have calmed down a lot. He did not reveal it immediately, but began to look for evidence that could kill the murderer.

[The evidence must be found! 】

Having figured out the murderer's modus operandi, Conan felt a little relieved. After relaxing, Conan discovered some things that he had not noticed when he was just concentrating on the case.

There is a strange smell in the house.

This taste is...

Conan followed the smell and looked for the source carefully. Then he smelled all the way behind Hirohiko Kido and saw what was accidentally exposed in his trouser pocket.

After seeing something like that, Conan immediately ran to the kitchen, pointed to the glass on the stove and asked, "Mother-in-law! Is this cup the one my mother-in-law uses to hold juice today?"

"Well, that's right. It's really strange that Zhen can wash the cup well." Mitsue Soda looked at the cleaned cup with some confusion.

After hearing Munada Mitsue's answer, a smile appeared on Conan's lips [It's true, I finally found the evidence! 】

Just when Conan smiled confidently, Kido Hirohiko looked at Aokimatsu and asked: "Officer, can I go back? I was drunk before, and now I feel a little uncomfortable. I want to go back and take a rest. .”

The murderer wants to leave!

Maybe it was because of his actions that he suddenly thought of that evidence.

After Conan heard Kido Hirohiko's words, he immediately became anxious. In addition, he had not subconsciously paid attention to his hand before, and directly reached out to pick up the crayon and put it in his trouser pocket. Later, he would definitely be caught by Mouri Kogoro and Aoki. Let's not scold him, so Conan more or less has the mentality of wanting to make meritorious deeds, and then the merits and demerits will be offset.

Before Aoki Song could answer, Conan immediately jumped up and said loudly: "I know!"

"Ah."

Conan's loud voice naturally attracted everyone's attention, and everyone looked at him.

Conan was not afraid at all. He looked at Aoki Song and said, "Brother Aoki, I already know the murderer's modus operandi."

At this time, Aoki Song is much more reliable than Maori Kogoro. At least Aoki Song will listen to his opinions seriously, while Maori Kogoro will only think that he is being naughty.

Naturally, the person Conan immediately looked for was Aoki Song.

Sure enough, after hearing what Conan said, Aokisong immediately looked at it seriously and said, "Is it true? Conan."

"Yes." Conan nodded. "Brother Aoki, I can demonstrate it to you now." After saying that, without waiting for Aoki Song's consent, he turned to Munada Mitsue and said, "Mother-in-law, lend me the key."

As expected by Conan, Mouri Kogoro immediately cursed: "Baga, how could you possibly know anything!"

Aoki Song immediately stopped Mouri Kogoro and said: "Detective Mouri, you have forgotten that Conan reminded you that the bathroom light was turned off just now. Don't underestimate Conan."

After finishing speaking, Aoki Song looked at Conan and said with a smile: "Conan, just do it. It doesn't matter if you make a mistake. Didn't your Uncle Maori make wrong reasoning several times just now? Don't be afraid."

"Yeah." Conan responded, pretending to be well-behaved.

[Sure enough, Brother Aoki is still reliable. 】

"Little brother, just have the key, right?" Mitsue Munada also looked at Conan kindly at this time and asked with a smile.

Conan nodded, "That's right."

"Take it." Mitsue Soda took the key out of his pocket and handed it to Conan.

"Thank you, please wait a moment." After Conan got the key, he immediately ran out of the living room, not knowing what he did.

Then I saw him taking a sweater and spreading it on the ground.

"What exactly do you want to do?" Mouri Kogoro stared at Conan's movements with a puzzled look.

Conan said with a smile while doing it: "You will know it soon!"

"By the way, mother-in-law, when I get outside, you will turn off the lights, just like when we came in!" After preparing everything, Conan asked Munada Mitsue to cooperate with his work later.

Mitsue Munada nodded, "Okay, no problem!"

"Okay, I'm going to start the demonstration. Everyone, please be quiet." After saying that, Conan opened the door and went out.

As Conan went out, Mitsue Soda also turned off the lights in the room, and the room immediately became dark.

When Mouri Kogoro saw Conan running out, he was determined to make up for Conan. If Conan failed, it would be embarrassing.

"boom!"

After a minute, a voice suddenly came from the room.

"It seems like something fell in." Aoki Song squinted his eyes, trying to see clearly what that thing was.

Through the moonlight, they saw what this thing was.

"It's a beetle, and it's a male beetle!" Mao Lilan said after carefully identifying it.

Qingmusong was stunned when he heard this, and immediately opened his eyes to identify it carefully. As his eyes gradually adapted to the dark environment, Qingmusong also saw the beetle clearly.

At this moment, the beetle had the key to the room tied to it and was crawling towards the deceased's room step by step.

Seeing this scene, Qingmusong understood instantly.

It turns out that the murderer’s modus operandi is…

Damn, this is missing the most crucial thing. Who the hell could have thought of such a modus operandi!

As for the cases involving beetles.

Compared with this case, what impressed Aoki Song more deeply was a certain theater version. After Matsumoto Kiyonaga was kidnapped by Ireland, a member of the winery, he was imprisoned in an abandoned hut in the rice flower forest. Matsumoto Kiyonaga used the tape from the lunch box to inhabit the beetle's body. A "V" is plastered on the back to call for help.

At this time, when Hirohiko Kido on the side saw the beetle, a trace of panic flashed in his eyes, and cold sweat began to flow from his head.
