A relatively high-end apartment.

In the elevator.

"The crime scene still maintained the appearance of the incident at that time, right?" asked Kogoro Mori.

Officer Otaki nodded, "Yes, but the victim's daughter has already agreed to come and pack up the relics tomorrow."

"Anyway, as long as we unravel this secret room trick today, there will be no problem." Hattori Heiji said without caring.

Next to him, Ye Que said: "Xiaolan, look, this elevator actually has windows!"

"It's very common to install windows on elevator doors recently," said Mori Ran with a smile.

"You two are so quarrelsome. We are going to the murder scene, not to come to play. Can you be more serious?" Hattori Heiji curled his lips.

"Of course I know this." He Ye Aojiao raised his head, "I have important tasks that only I can do."

"Important task?" Chen Xing couldn't help but look at him sideways.

Then when he arrived at the crime scene, he saw He Ye picking out the photos from his phone, squatting on the ground and comparing carefully with the overturned chair.

"Absolutely, this chair is exactly the same as my home!" she said: "Whether it is wood color or chair design, it is exactly the same. Hattori, this is indeed very strange."

At the end of the day, her fair little face was full of seriousness.

Hattori Heiji held his arm, "I'll say that from the beginning."

He Ye stood up, patted his knees, and smiled at Ran Mori and said, "The mission is completed!"

Looking at Ran Maori who was applauding her, Conan couldn't help but touch her forehead-even if she didn't come specifically to confirm the height of the chair, they could know the answer as long as they measured it.

"As a result, the question now is how the prisoner used to avoid the police's surveillance and enter and exit the room." Kogoro Mouri thought.

"Maybe there is some secret passage that can get into this room." Officer Otaki has always been very daring to think about it.

Chen Xing looked up at the air conditioner air vent, wondering if it was possible for someone to pass through it, and then he saw Conan squatting down in front of him.

"Pencil shavings?"

Below the upper rope passing through the air supply outlet, there was a cube of pencil shavings left, and there were several sharpened pencils in the pen holder on the TV cabinet next to it.

Chen Xing looked around and saw that from this room, the owner should be very fond of cleaning, but the cylindrical trash can in the corner of the room was overturned. Not to mention those who love cleaning, ordinary people would not let it fall there.

When he saw Hattori Heiji, he was stunned and walked over.

The guy squatted there with a speechless expression, and there was a sweeping robot in front of him.

Chen Xing had learned about this emerging high-tech product online, but after seeing Hattori Heiji's expression, a flash of inspiration suddenly flashed in his mind.

At the same time, Hattori Heiji, who noticed his approaching, sighed, "You should have discovered it too, earth?"

Chen Xing nodded, "Thanks to you to figure it out."

"Eh?" Hattori Heiji was a little puzzled.

Chen Xing smiled and pointed to the sweeping robot, "Because you have been staring at it, it seems like you are helpless."

Hattori Heiji spread his hands, "I thought it was such a bizarre secret room, but I didn't expect it to be so simple."

As he said that, he stretched out his finger, pressed the switch of the sweeping robot, and then the stupid little thing buzzed away.

"Wait a minute, Hattori." He Ye hurriedly said: "Don't move the things on the scene."

"I'm solving puzzles." Hattori Heiji said, walking to the corner and lifting the trash can. "When Mr. Guanyue hung himself, it was not the chair that was used as a trampling item, but the slender trash can."

He walked to the air vent of the air conditioner, "This thing was placed just under the rope. In order to stand up smoothly, he put the trash can in reverse. The evidence was that these pencil shavings that were concentrated here. The trash can was placed upside down, and all the pencil shavings stuck at the bottom of the inside of the trash can fell out."

As he said that, Hattori Heiji turned the trash can upside down on the ground, "Look, in this way, the height is higher than the chair, and it is enough for his feet, right?"

"But when I came in to investigate, it was not like this at all." Police Officer Otaki said.

Hattori Heiji glanced at the sweeping robot cleaning on the ground according to the route, and then kicked the trash can down with a light kick. "Don't worry, just kick the trash can between the feet of the chair when he is about to hang..."

While talking, the sweeping robot slipped over half a circle and pushed the cylindrical trash can away until the corner of the room.

"After that the cleaning robot pushes the trash can to the corner of the room. After it returns to the charging seat, the incredible hanging site will be arranged. The cleaning route of the cleaning robot is set to be only here, which is the ironclad evidence."

Hattori Heiji's tone was quite refreshed, "I think it was because I used to place obstacles in the middle of the room, so that the sweeping robot could remember this route."

After hearing this reasoning, Kogoro Mori and Officer Otaki were both stunned, "So, this incident..."

"Yes, no matter how I think, I'll commit suicide." Hattori Heiji spread his hands and walked out of the room first.

When everyone, or Kogoro Mori and Officer Otaki digested this reasoning conclusion, when they left the room at the crime scene, they saw Hattori standing against the wall in the corridor, looking up at the ceiling, looking deep and decadent.

"Heiji, are you okay?" He Ye said worriedly.

Seeing his depressed look, Chen Xing could probably understand. After all, the reason why he followed was probably attracted by the murder in the secret room.

He felt that this kind of killing method contained stories in the complexity.

"But why did Mr. Guanzuki choose that way to die?" When waiting for the elevator, Kogoro Mouri still couldn't figure it out.

Officer Otaki said: "He seemed to have borrowed a lot of money because of his failed stock investment. He hated the securities broker who failed to invest and once said at the banquet, 'I want to drag that person to hell', so I think he wanted to make the suicide case look like he was killed by a securities broker."

When Kogoro Mori shook his head and said, "But he was not lucky and didn't realize he was being monitored by the police. As a result, no one suspected that this incident was suspected of homicide, and it was immediately determined to be a suicide case."

He curiously said, "By the way, does that securities broker live nearby?"

Officer Otaki nodded and said, "Not to mention living nearby, he moved to this apartment about last year. I remember his name is..."

"You are talking about Mr. Bupu on the second floor." A fashionable housewife walked over from behind, and she said, "That person has caused everyone a lot of trouble in this apartment!"

"What?"

"He would chat up and discuss stocks when residents were waiting for the elevator. He would make a little money at the beginning, but when we invested a lot of money, we would suddenly lose a lot of money." The housewife said angrily: "My husband almost listened to him. I tried a lot of effort to stop him."

Her speech was fast and fast, obviously because she had been resentful of the securities broker for a long time, and then she criticized the guy's appearance.

"Oh, I'll say Cao Cao is here." She suddenly pointed to the elevator.

Everyone subconsciously looked over, and then through the glass window on the elevator door, they saw the thin middle-aged man with a smile on his face inside.
