My neighbor's name is Conan

As for the secret room, the most common ones are the old actors like "fishing line" and "adhesive tape".

Moreover, the victim Zhukou Yigui was wearing a ring.

This……

There is a feeling that is similar to you.

Ring, fishing line, secret room...it's all done!

Aoki Matsu can be sure that the death of Morokuchi Yoshiki was definitely a homicide, not a suicide.

It’s just that Aoki Matsu hasn’t figured out the modus operandi yet.

"But if it was suicide, why did Mr. Morokuchi hold the key in his hand before taking his last breath?" said Maruta Ayumi.

What he meant was that he thought this case was a homicide!

"Perhaps, this is because they don't want us who are staying in the villa to be suspected of murder." Maori Kogoro held up his chin and guessed, "As I said just now, if this is a homicide case, if he didn't lock the door with the key and drink the coffee... this kind of situation would not have happened."

"But it's also possible that someone copied the key!" Qing Musong retorted: "That way, they can easily enter and exit here."

This trick is Kaito Kid's specialty, but most of the time Kaito Kid copies faces and fingerprints, not keys. After all, he is a thief who can use a piece of wire to open very complicated locks.

"Impossible. There is only one key to the master bedroom, and it has always been in Mr. Morokuchi's hands. No one else has the chance to access it." Anabuki Haruei retorted.

Qing Musong thought to himself, "So, it could only be that the old actor performed on stage and staged a murder in a locked room! The key point is how the murderer got the key into the palm of the victim's left hand after killing the person and locking the door. 】

"So, did Mr. Morokuchi show any signs of wanting to commit suicide before?" Aoki Matsu asked Anabuki Haruei and the other two.

Anabuki Haruei lowered his head and frowned before smiling and answering, "No, nothing special."

Tarumi Wataru said, "I can't see anything wrong with Mr. Morokuchi at all."

Dejima Kakuji looked at Anabuki Haruei and said, "Yes, that's it."

"Perhaps Mr. Morokuchi has some troubles that he cannot tell others! Mr. Akibaba, Mr. Morokuchi's former editor-in-chief, also committed suicide this spring, didn't he?" Maori Kogoro reasoned, "Perhaps he feels that he is also responsible and is in a heavy mood."

After hearing what Kogoro Mori said, Aoki Matsu had a different idea - Mr. Akibaba might have been killed by Morokuchi Yoshitaka.

Then, one of the three people including Anabuki Haruei had a very good relationship with Mr. Akaba, and they were even in a relationship. They did not believe that Mr. Akaba committed suicide, so they approached Morokuchi Yoshiki to find out the truth.

As a result, the truth was found out not long ago, and it was discovered that it was Morokuchi Yoshiki who killed Mr. Akibaba, so they killed Morokuchi Yoshiki to avenge Mr. Akibaba!

He had handled this kind of case before, the case of the Death God. Because he was called "Death God", Qing Mu Song remembered it very clearly!

Anabuki Haruei might be Mr. Akibaba's girlfriend, and Dejima Kakuji and Tarumi Wataru might be very, very good friends with Mr. Akibaba, so...

As for killing someone to avenge a good friend, this kind of thing is not really outrageous in the world of science. Not to mention distant examples, aren't Mizuguchi Kana and Koshimizu Nanatsuki good examples?

After realizing this, Aoki Matsu quickly looked at Anabuki Haruei and the other two, trying to see something from their expressions.

It’s a pity, I don’t know if it’s because the little black man is awesome or he met “Conan can laugh”, anyway, Aoki Matsu couldn’t tell anything from the expressions of the three people.

Qing Musong thought for a moment and said, "That's it for now. We'll talk about it after the forensic department collects evidence. Please wait in the living room. Thank you for your cooperation."

He needed evidence and time to think about how to commit the crime.

This case was a homicide, so evidence would definitely be found in the room - because Aoki Matsu remembered that the case where no evidence was found was not that case.

As for Conan's other cases, evidence can be found, but some of the evidence is not strong enough, leaving room for explanation.

"Yes!" Anabuki Haruyoshi and the other two responded.

Maori Kogoro said at this time: "Inspector Aoki, I think it must be suicide. There is no need to call the forensic department."

Hearing this, Aoki Matsu looked at Maori Kogoro and said, "Detective Maori, if you keep thinking this way, there is actually another possibility for this case, but I have never wanted to think about it that way."

"What's possible?" asked Kogoro Mouri curiously.

Aoki Matsu said seriously: "That means it is possible that Conan did it, because Conan can enter and exit this room without the help of any tools. From an absolutely rational point of view, Conan is also a suspect. Who says that a child can't kill someone?

As Conan's guardian, you have always insisted that Mr. Morokuchi committed suicide. Is it possible that Conan actually followed your instructions, crawled into the room, hid under the bed, and then took the opportunity to put cyanide in Mr. Morokuchi's coffee, and then climbed out through the air vent. So you are also a suspect."

"Ah!" Everyone was stunned by Qing Musong's reasoning.

Mao Lilan said subconsciously: "Brother Aoki, how could my father and Conan be the murderer!"

Kogoro Mouri and Conan were also dumbfounded. When did they become the murderer?

Qing Musong continued seriously: "Just tell me, can Conan do what I said?"

Although it is indeed impossible for Conan to be the murderer of Morokuchi Yoshiki.

But according to Aoki Matsu's modus operandi, Conan was able to kill Morokuchi Yoshiki and disguise it as suicide.

Because Conan can indeed enter and exit this room freely through the air vent without any tools.

At the same time, Zhukou Yiqi died from the cyanide in the coffee, not from being stabbed with a knife or strangled with a rope, so there is no difference in martial power, and he can be defeated by intelligence.

"Ah, this..." Kogoro Mouri was dumbfounded. According to what Aoki Matsu said, Conan was indeed a suspect, and to some extent, he was more suspicious than Anabuki Haruei and the other two.

And because Conan is a minor and Mouri Kogoro is his guardian, so - rather than Conan killing Morokuchi Yoshiki for no reason, a better reason is that Mouri Kogoro instigated Conan to pour something in Morokuchi Yoshiki's coffee, and he could have lied to Conan that it was syrup or something, and then used it to kill Morokuchi Yoshiki.

So both Kogoro Mouri and Conan became suspects.

Of course, emotionally and scientifically, the two were not the murderers. But logically and rationally, they were suspects!

"You little brat, if it weren't for you, how would I have become a suspect!" Kogoro Mouri punched Conan in angrily, and felt like he was hit by a cauldron falling from the sky.

Conan couldn't dodge Kogoro Mori's fist. After being hit, he quickly hid aside, rubbing his head, pouting and looking at Aoki Matsu speechlessly.

When Aoki Matsu heard him crawling in through the air vent, Conan saw that Aoki Matsu didn't react. He thought Aoki Matsu was used to him being there, so he didn't make a big deal about some of his "unruly" behavior.

I didn't expect that you were waiting for me here!

[Sure enough, Brother Aoki is still the same Brother Aoki as before, he hasn't changed at all. 】

After realizing this, Conan mentally tightened his grip. He was indeed a little bit arrogant today. If he were in other places, those criminals wouldn't say anything. But now that he was caught by Aoki Matsu, it would be strange if he didn't teach him a lesson.

Because of what Aoki Matsu said, Kogoro Mouri and Conan also became suspects, so the Mouri trio were also invited to the living room.

While waiting for the forensic detective to arrive, Aoki Matsu was not idle either. He looked at Anabuki Haruei and the other two and said, "Can I ask you a few questions first? Before finding Mr. Morokuchi's body, where were you and what were you doing? Let's start with Mr. Dejima."

Upon hearing this, Kakuji Dejima stuttered and said, "I, I was repairing this tape recorder in my room. I don't know what the problem is, but the tape inside is twisted and deformed. Whenever I rewind it, you can hear this sound." As he said that, he showed the tape recorder in his hand and pressed a button for everyone to listen.

A "squeaking" friction sound came from the tape recorder.

Aoki Matsu raised his eyebrows upon seeing this.

The tape recorder was a tape type, and the tape was warped.

Tsk, it’s done!

[Dejima Kakuji, the key suspect is you! 】

"Is this recorder yours? Has it been used by anyone else?" asked Aoki Matsu.

Upon hearing this, Dejima Kakuji said, "The recorder is mine. I have never lent it to anyone else. But I placed it directly in the room before. I wonder if anyone has used it while I was not in the room."

"When was the last time you used a tape recorder?" Aoki Matsu asked.

"It was yesterday morning. I listened to music on the tape recorder on my way here." Dejima Kakuji replied.

Aoki Matsu glanced at him after hearing this, and then said, "I understand. Mr. Tarumizu is next."

Although it is believed that Kakuji Dejima is the most suspicious, it is also possible that the murderer knew that Kakuji Dejima would bring a tape recorder, so he deliberately tampered with Kakuji Dejima's tape.

Therefore, we need to listen to the other two suspects.

Upon hearing this, Tarumi Wataru replied, "Me too. After completing the preparations for today's photography, I stayed in the room and started organizing the negatives for other work! I tied them up with these rubber bands." As he spoke, Tarumi Wataru raised his left hand to show Aoki Matsu and others the several rubber bands on his left wrist.

"I understand. Then the next one is Miss Anabuki." Upon hearing this, Aoki Matsu turned his attention to Anabuki Haruei again.

"I was also in the room confirming other writers' schedules in advance," Anabuki Haruei replied.

At this time, Conan suddenly interrupted and said, "Brother Aoki, I remember that Aunt Anabuki had a metal measuring tape on her body!"

He wanted to make up for his mistakes by "making meritorious services".

In Conan's eyes, Aoki Matsu is a man who knows how to reward and punish, so he should be able to make up for his mistakes.

To some extent, a measuring tape can also do the "work" of fishing line, magnetic tape, etc.

Hearing this, Aoki Matsu looked at Anabuki Haruei and asked, "Is that true? Do you always carry that measuring tape with you?"

"Eh!?" Anabuki Haruei was stunned for a moment, then replied, "Yes, because the teacher often asks me to measure things, such as the size of words."

"But if you're just measuring words, wouldn't it be fine to use an ordinary ruler? Why use a tape measure?" asked Aoki Matsu.

Before Anabuki Haruei could answer, Tarumi Wataru next to him complained, "It's not just the words that need to be measured. Mr. Morokuchi also requires a lot of things to be measured."

Dejima Kakuji also chimed in, "Like a door or window that can be used as a trap."

Qing Musong raised his eyebrows and said, "You know it very well!"

But it is obvious that none of the three are Morokuchi Yoshiki's assistants, and only Anabuki Haruei is the editor-in-chief of Morokuchi Yoshiki. This is a bit strange!

"The late Akibaba often told us about Sensei Morokuchi when he was alive," Tarumi Wataru explained.

"Because he entered the publishing house at the same time as the three of us." Anabuki Haruei also said.

Dejima Kakuji also responded: "It's just that I quit my job and became a freelance writer."

[We are the same age, so I think he has a stronger motivation to avenge Akibaba.] Aoki Matsu thought to himself.

"I see." Aoki Matsu nodded perfunctorily.

Later, the detective from the Forensic Science Division arrived. Aoki Matsu asked Kogoro Mori and others to stay in the living room, and he and the detective from the Forensic Science Division inspected the crime scene together.

The first is the body of Zhukou Yiqi, with the focus on the left hand.

There was a key in the palm of his left hand, and a ring on his middle finger, but it was worn backwards.

After the forensic detective took photos, Aoki Matsu turned his left hand over and found that it was a ring inlaid with many diamonds.

"Has the ring ever been taken off and put on again?" asked Yoji Aihara.

Maruta Ayumi thought for a moment and said, "Inspector, could it be that the murderer wanted to kill Mr. Morokuchi because of this ring? And he also made an identical fake one to replace it?"

Qing Musong shook his head when he heard this. "Impossible. Although this ring has a lot of diamonds on it, they are all small pieces. They may be valuable when you buy them, but if you want to sell them, they are worthless. Diamonds depreciate very quickly."

Each of these diamonds is estimated to weigh less than half a carat and is not worth anything at all.

Moreover, compared to the murderer's killing of Morokuchi Yoshiki because he was attracted by the diamond ring, which was a bit outrageous, Aoki Matsu still felt that it was more reasonable to avenge Mr. Akibaba.

"However, if your idea is replaced with antiques or something like that, it is possible." Aoki Matsu did not discourage Maruta Ayumi. If the diamond ring was replaced with an antique vase, it would really be possible.

The case of a certain classmate Douzi was handled in the same way.

He said that the authentic product was stolen by Douzi, who sold counterfeits privately. Then Douzi found out the truth, sent the other party to prison, and restored his "reputation".
