The famous criminal in Conan's world

What are the books piled high up to cover up?

What is the opera playing on the record to cover up?

Bai Masong has no recollection of this case.

He does have an impression of Hattori Heiji, but as far as he can remember, the first time he saw Hattori Heiji was in an episode in Osaka.

Although he doesn't remember this case, the clues at the scene seem to have made him vaguely touch the truth.

"Sato," Bai Masong suddenly said,"you come and analyze these people."

In Bai Masong's reasoning, this case should also be considered in line with his"scientific skills"

"Yes!"

Sato Miwako quickly agreed.

At this moment, a high-spirited voice came from outside the door.

"No need!"

Everyone turned their heads and looked over.

They saw the high school detective, Hattori Heiji, who had just left for a while, and he was back again.

"I already know the method of this secret room!"

Hattori Heiji said

""What!?" Inspector Megure exclaimed,"Brother Hattori, do you really know the locked room technique?"

As he spoke, Inspector Megure glanced in the direction of Hakuba Matsu.

Inspector Megure is also a knowledgeable person. He has experienced three detectives, Kudo Yusaku, Kudo Shinichi, and Mori Kogoro, as well as Hakuba Matsu, a leader in the police force. In his opinion, his brother Hakuba can be said to be the most capable one.

But now, brother Hakuba is still thinking, this Hattori Heiji has already solved the mystery?

Hakuba Matsu glanced at the high-spirited Hattori Heiji, and wanted to hear what he had to say, so he returned a look to Inspector Megure, motioning him to take a look first.

On the other side, Conan, who was suffering from a cold and white wine, also wanted to go out to solve the case, but when he thought that there was Hakuba Matsu, who could always beat him, he would rest assured to recuperate.

Hattori Heiji listened to Inspector Megure's question and said confidently

"Officer Megure, your body type is similar to that of the deceased. Could you, please, be the deceased for a moment?"

"No problem," said Officer Megure.

"Bang!"

Just as Hattori Heiji was about to demonstrate, Conan finally couldn't stand it anymore and fell to the ground

"Conan!"

Xiaolan immediately picked him up and called out with concern.

"This little brother must have a fever, why don't you let him go to my room to rest for a while."

Takayoshi Tsujimura said kindly.

""Okay, thank you very much, Mr. Guishan." Xiaolan thanked

"It's okay. My room is on the first floor. You can take your little brother there."

""Okay."

After saying that, Xiaolan took Conan downstairs and went to Takayoshi Tsujimura's room on the first floor.

"Ahem, Brother Hattori, please continue your demonstration now."

Inspector Megure waited until Xiaolan carried Conan away and continued

""Okay," Hattori Heiji said,"At the time of the incident, all the windows of this room were locked from the inside, and the only door that could be used for entry and exit was also locked with a key."

"In this way, a secret room with no gaps is formed inside. But this seemingly completely secret room still has a gap."

"Gap?" Everyone asked in confusion.

"That's right, it's the gap under the door!" Hattori Heiji pointed at the gap and said with a smile

"You're not saying that the murderer slipped the key into the victim's pocket from under this gap, are you?" Maori Kogoro looked doubtful.

Faced with the doubt, Hattori Heiji was not in a hurry.

"You are right, the murderer threw the key into the victim's pocket through the gap, and it can be done with tape and the fishing line I just found!"

As he said this, Hattori Heiji took out a circle of fishing line from his pocket, then walked to the side of Officer Megure, took out a needle, and motioned to prick Officer Megure.

"The murderer first stabbed the victim's neck with an iron needle soaked in poison, killed him, and then found the victim's key in his pocket."

"Then, take out the fishing line, tie the iron needle on one end of the fishing line, and stick the other end to the tape on the keychain to fix it."

"Then, pass the end with the needle through the deceased's trouser pocket, and then place the deceased in the same position as we saw at the beginning."

Hattori Heiji finished saying these words, and Officer Megure was also placed in the same position as when Tsujimura Isao died. Then, Hattori Heiji held the end of the fishing line with the needle in one hand and the end with the keychain in the other, stretched them out, and pulled them out the door.

"After that, we just need to hold both ends of the fishing line and walk out of the door, then we can pull the fishing line out of the door through the gap, then lock the door with the key, and pull the fishing line to pull the key in."

As he said, Hattori Heiji pulled one end of the fishing line, and then the key was slowly pulled in from under the door gap little by little as he spoke, crawled over the carpet in the study, climbed onto Tsujimura Isao's desk, and finally, fell into Inspector Megure's pocket.

Seeing that the key really went into Inspector Megure's pocket, Inspector Megure himself and Maori Kogoro were both shocked.

"Finally, with a strong pull, the stuck fishing line will separate from the keychain, and the key will remain inside. Then roll up the fishing line, and the evidence will disappear."

Hattori Heiji put an end to his reasoning with words and actions.

After he finished speaking, a confident and complacent light flashed in his eyes, and he thought to himself, I am still better in this competition, and this time, I won!

After hearing this, everyone was silent. Almost everyone thought in their hearts that he was worthy of being the son of the chief of the Osaka Prefectural Police Department and a famous high school detective in Kansai.

Of course, this was only almost.................

Bai Masong had no such thoughts at all. He continued to ask Sato Miwako as if nothing had happened.

"Sato, who do you think is most likely the murderer?"

"Huh?"

When Miwako Sato heard Hakuba Matsu suddenly calling her, she hesitated for a moment. Wasn't the case solved by Hattori Heiji?

"Sato!" Bai Masong said again

"Ah, yes!" Sato Miwako answered loudly

"Let me think, if we look at the alibi, it should be………………"

"Hey, two officers," Hattori Heiji said with a little dissatisfaction,"Don't bother you to analyze, I have already deduced the real murderer."

Bai Masong shook his head slightly and said in his cold, emotionless voice

"You were going in the wrong direction from the beginning, let alone trying to figure out the real culprit."
