The famous criminal in the world of Conan

"What!?"

When everyone heard Bai Masong's words, they couldn't help but exclaim.

Hattori Heiji felt even more unconvinced and questioned Bai Basong.

"Why do you say my reasoning is wrong?"

Bai Masong looked at Hattori Heiji who had a look of dissatisfaction, and spoke calmly without changing his tone.

"Your reasoning has always been theoretical. In reality, it is simply impossible to do it."

"Haha," Hattori Heiji laughed after hearing what Hakuba Matsu said, "You just saw me put the key into Inspector Megure's pocket with your own eyes. How can you say that my method is just theoretical?"

"Yes, yes, Brother Hakuba..." Inspector Megure couldn't help but say.

“The key went into his pocket, but did he double-pocket it?

Hakubamatsu interrupted Inspector Megure and asked casually.

Into the double pockets?

"This, this is of course going in!"

Hattori Heiji hesitated for a moment and said affirmatively,

"If you don't believe me, we can give it a try!"

Bai Masong listened to Hattori Heiji's argument without answering. He just nodded his pocket and signaled him to go ahead.

Of course Hattori Heiji would not back down. He immediately walked towards Inspector Megure and hurriedly reached his hand into Inspector Megure's pocket.

"What!?"

"How can it be!?"

Inspector Megure and Hattori Heiji couldn't help but shout.

They saw that the key fell out of Inspector Megure's pocket and did not enter the double pocket.

"This, this..." Hattori Heiji was very puzzled, "Could this be a coincidence?"

Bai Ma Song shook his head.

"That was your first fault in this instance, you did not notice that the deceased was sitting."

"Sitting? What do you mean?" Hattori Heiji asked humbly.

"Inspector Megure is obese, and the deceased is even more obese. When they sit, their pockets are severely folded. Before the key enters the double-layer pocket, it will be forced to disconnect from the fishing line due to the folding."

"But there may be unexpected situations. What if we can get in?" Hattori Heiji asked.

"No, look carefully at the direction of the key and the key chain." Bai Masong said.

"direction?"

Hattori Heiji looked over and recalled it carefully.

Suddenly, something occurred to him.

"You probably figured it out. When we found the key, it and the keychain were folded together. But your method can't fold them together."

Hakuba Matsu saw through Hattori Heiji's thoughts and solved the mystery.

"Not only that, you made another mistake." Bai Masong continued.

"What?" Hattori Heiji asked. At this time, he no longer had confidence and just wanted to hear if he had any other flaws.

"Poison needle." Bai Masong said

"Poison needle?" Hattori Heiji muttered

"Have you ever thought about how you put the poison needle in there? You know, we found it next to the desk."

Yes, yes, the key is in, but how do we get the poison needle in there, since it’s a needle and thread thing?

“This, this………………”

As Hattori Heiji thought about it, sweat broke out on his forehead. He found that his reasoning was like child's play in front of this police officer.

Coupled with the cold, serious, and somewhat instructive and admonishing tone of the white-horse police officer, Hattori Heiji felt different.

He felt like he was facing his father, who was the Chief Superintendent of Police.

When Hakubamatsu saw that Hattori Heiji realized his problem, he stopped keeping the matter in suspense and spoke calmly.

"These two questions are enough to show that your reasoning is incorrect."

"Then how did the key get in?" Hattori Heiji asked humbly.

"The key has never gone out." Bai Masong said.

"Then, the suspect......" Hattori Heiji asked again.

This time he didn't need to finish, everyone knew what he wanted to ask.

How did the suspect get out?

"The suspect doesn't need to go out at all." Bai Masong resolved everyone's doubts.

"What are the books piled high up, and the opera playing in the room when you came in for?"

Baimasong spoke in a gentle and persuasive manner.

"What's it for?" Hattori Heiji asked anxiously.

"The books piled high are to hide. The opera playing is to cover up."

Bai Ma Song continued.

"What exactly are you covering up? What are you hiding?"

Bai Ma Song's words made Maori Kogoro on the side unable to bear it. He couldn't wait to ask

Bai Masong did not say anything, but just looked quietly at Hattori Heiji on the side.

After hearing what Hakuba Matsu said, Hattori Heiji felt as if he had touched something and an inspiration flashed through his mind.

"I understand!" Hattori Heiji shouted excitedly, "The murderer wanted to cover the face of the deceased and hide the possible screams of the deceased!"

"But who was the murderer trying to protect himself from?"

Kogoro Maori still didn't understand and asked again.

"To guard against you." Bai Masong said lightly from the side.

"On guard against me?"

Kogoro Mouri pointed at himself, looking confused.

"To be precise, I'm on guard against everyone who comes in with you. Right, Mrs. Tsujimura Kimie?"

Bai Masong said directly.

I was originally thinking about training Sato Miwako, but was interrupted by Hattori Heiji. Seeing that Hattori Heiji seemed a little impatient, I got angry and wanted to give her some advice.

Now that he saw that Hattori Heiji had calmed down and found the answer, Hakuba Matsu didn't plan to drag it on any longer.

"What!?"

Bai Masong's words were like throwing a stone into the lake, which caused a thousand waves and made everyone present boil with excitement.

"Madam killed the master, this, this is impossible!"

Butler Fumio Koike was the first to raise questions.

"Nothing is impossible," Bai Masong said calmly, "The key in the double pocket is enough to prove that the key has never left the pocket of the deceased. Then, Mrs. Tsujimura Kimie, who also holds the key, you are the biggest suspect."

"First, knock Tsujimura Isao unconscious, and then pose like this. Then, wait for Detective Mori and the others to follow you in, and prove that this study is a secret room. Then, your trick will be complete."

"After you come in, you just need to pretend to wake him up, but actually give him an injection. Since the poison takes effect very quickly, Tsujimura Isao will die under your needle before he can react. This way, people will think that he has already died."

"To prevent Tsujimura Isao from showing any pain, you piled a pile of books on the table. To cover up his possible screams, you played opera in the study."

"In order to frame others and lure the police into a trap, you must have placed fishing lines in every corner of this house."

"These are all your modus operandi."
