My neighbor's name is Conan

Facing Aoki Matsu's question, Katsuragi Kensuke, sweating profusely, said in defense, "That was because I was too nervous at the time and didn't think that she might have the key."

"No!" Aoki Matsu denied what Katsuragi Kensuke said, "You were in a hurry to break the skylight in order to prevent the hole you had made in the skylight from being discovered by others."

"No!" Kensuke Katsuragi overreacted when he heard this. He stood up from the sofa and loudly refuted Aoki Matsu.

"Then I want to ask, after you broke the skylight and jumped into the room, there were clearly several bunches of keys on the floor. But according to Detective Mori, you reached out and grabbed the key to the studio room without hesitation. How did you know that key was the key to the door of the studio room?" Aoki Matsu asked Kensuke Katsuragi with a stern face.

"It's because of the keychain!" Katsuragi Kensuke answered without thinking, "Because I know that the keychain is hung with a chain with a blue gem, so I can identify it quickly."

Qing Musong smiled when he heard this, "But this is strange. The keychain was clearly replaced by Teacher Lihua not long before the incident. When Teacher Lihua went to the studio on the second floor, Xiaolan asked Miss Lihua to help her with divination. Teacher Lihua gave it to Xiaolan as a talisman."

"Eh!?" Kensuke Katsuragi's face changed drastically when he heard this. He had never expected such an accident to happen.

"Isn't that right, Xiaolan?" Aoki Matsu asked.

"Yes." Upon hearing this, Mao Lilan took out the key chain that Shibata Reika gave her from her skirt pocket.

"In other words, the blue gem key chain was a pendant that was put on after Teacher Reika entered the studio. Logically speaking, you have never met or spoken to Teacher Reika since then. How would Mr. Katsuragi know that it was that pendant?" Aoki Matsu looked at Kensuke Katsuragi and asked.

Kensuke Katsuragi's previous testimony was that after Reika Murasaki left the living room, Kensuke Katsuragi first talked with Yuka Shiraishi in the reception room, then handled official business in the reception room himself, and then walked out and stayed with Kogoro Mori and Masao Tamura.

Judging from Kensuke Katsuragi's testimony, he will never have the chance to contact Murasaki Reika again.

"Ah!" Kensuke Katsuragi's face turned grim when he heard that. His whole body tensed up and he broke out in a cold sweat.

Seeing Kensuke Katsuragi like this, Aoki Matsu knew that he was about to lose his temper, so he continued, "Knowing that the key with the blue gem pendant is the key to the studio room door, apart from Teacher Lihua, the only other person left is the murderer who created the secret room as a disguise and used the key. Mr. Katsuragi, it's you, right?"

Faced with the recording in the mobile phone and the fact that the key chain pendant had been replaced in advance, Kensuke Katsuragi could not hold it in any longer. After lowering his head, he suddenly put his hands on the coffee table, his face full of fear and resentment. "It's all that woman's fault. She suddenly asked me to repay all the money she had invested so far. If I couldn't do it, she would sell the information I got from the printing factory to the weekly editor for insider trading and expose it. She threatened me..." When he said this, Kensuke Katsuragi burst into tears.

"If you hadn't done anything wrong and violated the law and morality, how could you be threatened by her? Did she force you to do insider trading?" Aoki Matsu said coldly to Kensuke Katsuragi.

Although Zi Tiao Lihua is not a good person, the cause and effect relationship cannot be mistaken.

Just because Murasakijo Reika is not a good person, it doesn't mean that Kensuke Katsuragi is fine.

Neither of them is a good person.

But people's bad habits mean that when something is to be blamed, they will subconsciously put the blame on others rather than themselves.

"Take it away." Aoki Matsu said to Maruta Ayumi who was standing beside him.

There's not much to say about people like Kensuke Katsuragi.

After asking the Maori trio and confirming that they didn't need him to give them a ride, Aoki Matsu got in the police car and returned to the Metropolitan Police Department.

But he didn't go up, but went home.

It’s late at night, so everyone should go home and sleep first, and do things like taking notes tomorrow.

***

"Detective Mori, could you please not go out so late next time?" Aoki Matsu rolled his eyes at Mori, Kogoro and the other two at the crime scene.

"Ah, he has to go to work, so we can only agree to talk after he gets off work." Kogoro Mouri said, scratching his head embarrassedly.

There was no way. This time, the murder was discovered after get off work, and the criminal police were asked to work overtime.

Aoki Matsu walked to the crime scene resignedly. According to the old rules, he let Maruta Ayumi and others go through the process first.

Then he looked at Maori Kogoro and asked, "Detective Maori, please tell us what happened."

Maori Kogoro heard this and told the story, "It's like this, President Somei brought Miss Kuzumi to the detective agency and invited me to appear on the program "24 Hours Following Maori Kogoro". In order to discuss the details of the program with them, I made an appointment with Mr. Somei and came here, to the apartment of Mr. Nakame Raisaku, the producer of Toudou TV, to discuss it.

But when we got here, no one answered the doorbell no matter how long we pressed it, so we asked the administrator to open the door and cut the security chain. After coming in, Mr. Somei searched the living room and I searched the study.

Unexpectedly, Mr. Somei saw Mr. Nakame lying on the floor of the living room. I hurried over after hearing President Somei's voice. I briefly checked Mr. Nakame and found a faint smell of almonds in his mouth, which should be cyanide. "

"Is that so!" Aoki Matsu nodded, then looked at Maruta Ayumi.

Maruta Ayumi understood and took out the small notebook and said, "The deceased is Nakame Raisaku, male, 52 years old, a producer at Toudou TV."

"Has the cause of death been determined?" Aoki Matsu asked again.

The forensic detective nearby replied, "It's hard to say too much about the details before the autopsy results come out, but this should be correct. According to my guess, the time of death should be around 6:30 pm."

"Well, but you guys really insisted on coming into the house and even cut the security chain." Aoki Matsu looked at the only "outsider" present, Somei Shogo, and said.

This person is also the president.

Aoki Matsu was a little suspicious of him.

There is no way, since the other party is the president, the president of the Science World has a built-in buff.

Maori Kogoro also looked at Somei Shogo and said, "We heard it from President Somei. President Somei said that Mr. Nakame had expressed the idea of ​​committing suicide several times recently, so we felt that the situation was urgent."

"Yeah!" After Kogoro Mori finished speaking, Somei Shogo nodded to indicate that it was correct.

Can……

After hearing what Kogoro Mori said, Aoki Matsu became even more suspicious of him.

Saying that the other person committed suicide, isn't that just adding drama to the death?

As we all know, the person who adds drama is most likely the murderer.

"But we can't rule out the possibility of homicide." Maruta Ayumi interrupted.

Aoki Matsu nodded, "Yes."

Just because the Maori trio were at the scene, this case was definitely not suicide, but homicide!

Instead, Somei Shogo was a little surprised and actually asked, "Huh, why? Isn't it obvious that it was suicide? Because the entrance door was not only locked, but also hung with a security chain."

Ah!

For a moment, Qing Musong didn't know what to say.

Brother, the more you say that, the more suspicious you become.

Only a murderer would be so eager to classify a case as a suicide.

Therefore, regarding Somei Shogo's behavior, Aoki Matsu had only one thought: He was anxious! He was anxious!

Maruta Ayumi explained, "Indeed, this room makes people feel like a secret room, but even if the deceased died of poisoning, it doesn't necessarily mean suicide."

"Yes, is that so?" Somei Shogo responded with some stupidity in his clear eyes.

"It's possible that the murderer visited the victim's room with a cake, poisoned the coffee, and then left the place on the pretext of having something urgent to do. He deliberately said that the security was bad recently and asked the victim to be careful, so that he could successfully make the victim hang up the anti-theft chain, thus making it easy to create a secret room." Maruta Ayumi further explained.

Maori Kogoro went on to say, "After the murderer left, Mr. Nakame sat down and drank the poisoned coffee, and he fell into the murderer's trap!"

"I see." Somei Shogo said with an unnatural look.

Seeing this, Aoki Matsu stepped forward, looked at Somei Shogo and said, "By the way, where were you at the estimated time of death, which was around 6:30?"

"Me?" Somei Shogo was shocked and looked at Aoki Matsu in disbelief. "Do you doubt me?"

【certainly! 】

But there is no evidence now, and in the world of science, not every president will end up as a murderer. For example, the one in Mantiantang is alive and well.

So Somei Shogo is just a big suspect now.

"No, because you are the first person to discover it, we are just asking you according to the procedure." Aoki Matsu said.

Somei Shogo's expression relaxed a bit when he heard this, but he still felt a little unnatural, as if he was hiding something in his heart. He lowered his eyes and did not dare to look directly at Aoki Matsu and the others. "Because I haven't been feeling well recently, I asked for leave from the company and went home to sleep.

Then, around 7:, I received a call from Mr. Maori, and I remembered that I had an appointment with Mr. Nakame tonight at o'clock, so I rushed here. I felt much better after a day's sleep. "

Maori Kogoro, who had been listening to Somei Shogo's words and nodding to show that Somei Shogo was right, immediately said after hearing the last sentence: "Well, wait a minute."

Aoki Matsu thought that Maori Kogoro had remembered some clues, but he just angrily yelled at Somei Shogo: "So, you forgot about the meeting?"

"Ah!" Somei Shogo lowered his head slightly in embarrassment, not daring to look Mori Kogoro in the eye. "Yes, I'm sorry."

"Did you answer that call using your home phone?" Aoki Matsu asked.

Somei Shogo shook his head and took out his cell phone from his pocket, saying, "No, I answered it on my cell phone."

amount……

This makes Somei Shogo a greater suspect.

However, out of caution, Qing Musong still asked again, "So, can anyone prove that you slept at home all day today?"

"That, that's not the case." Somei Shogo answered subconsciously, then suddenly realized what was happening and raised his voice several degrees. "You said proof, you really are doubting me, right?"

"No, no, it's just to be on the safe side." Maruta Ayumi hurriedly stepped forward to play the good cop.

Aoki Matsu saw that Somei Shogo had become alert, and further questioning would only increase Somei Shogo's vigilance, so he stopped questioning him and searched the scene instead.

The victim was lying in the living room. His body was estimated to weigh more than 250 pounds and should not have been moved after death.

Next to the victim was a set of tables and chairs, on which was a cup of coffee and a piece of cake.

Qing Musong went forward and picked them up one by one to check. Unexpectedly, he really found a clue - there was no coffee liquid under the coffee plate, and there were two very thin marks on the traces of coffee flowing out of the cup.

Generally speaking, if coffee flows out from under the plate, it should leave a circular mark on the bottom of the plate.

But there was no circular mark on the table in front of him, and there were two very strange thin marks left.

It seems that there was something blocking these two places when the coffee liquid came out, so no coffee liquid was left.

After careful identification, Qing Musong found that it was probably left by a coffee cup that had fallen over and its handle.

It stands to reason that if you knock over a cup of coffee and it's in close contact with the table, the coffee won't get on the handle.

That is to say, after the victim drank the poisoned coffee, someone deliberately put the coffee cup into the plate and put it back on the table. And it was after the coffee on the table dried up.

This man is suspected to be the murderer.

But why do this?

Besides that, Somei Shogo was the one who could have done it, since he had advanced into the living room and had a minute or so to do it.

The reason why Aoki Matsu suspected Somei Shogo was not because of science, but because after the coffee was poured on the table and absorbed by the tablecloth, it would take an hour to dry.

If we speculate that the crime occurred at 6:30, then Kogoro Mouri entered the originally locked house after 7:30 and before 8:00.

It takes from one hour to one and a half hours for the coffee to dry up.

Before that, Somei Shogo rushed in first, and it was Somei Shogo who directed Mori Kogoro to go to the study, and he went to the living room.

No matter how you look at it, Somei Shogo is the most suspicious.

I didn’t expect that this case would be a long-lost proof question.

Now all that's left is the evidence.

But this is not evidence.

It's just that there were no traces of coffee under the plate where the coffee was placed. This can only prove that Nakame Yosaku was not murdered but committed suicide, but it cannot prove that Somei Shogo was the murderer.

What's even more strange is why the murderer wanted to cover up this trace?

It’s okay if you don’t cover it up!

Not everyone needs a tray for coffee.
