Said, Hattori Heiji came to the right side of Officer Megure, reached into the double pocket on Officer Megure's pants, and searched carefully, but when he When I took out the inner pocket, the key fell out of the outer pocket with a crisp sound.

"Ta la!"

Seeing this scene, Hattori Heiji's pupils shrank suddenly, and he couldn't help but lost his voice,

"ah? What? how could be?"

Hattori Heiji hurriedly knelt down and picked up the key on the ground. Unexpectedly,

"I had clearly let the fishing line pass through the innermost pocket just now. How could this happen?

Bai Di explained calmly,"This is because Officer Mumu, like the deceased, is sitting on a chair.""

"What did you say?"

Hattori Heiji couldn't help but have a look of disbelief on his face.

"Because as long as you sit down, the pocket will wrinkle, blocking the key's passage into the pocket. The fishing line had been pulled out of the tape before the key entered the innermost pocket.

Moreover, the deceased was fatter than Officer Megure, so the wrinkles in his pockets would naturally be more severe."

Hearing Baidi's reasoning, Officer Megure couldn't help but recall the situation at that time. It was indeed what Baidi said.

However, Hattori Heiji said to Baidi in a panic,

"This is very possible, no, there will be at least one coincidence out of ten."

Bai Di shook his head and firmly denied,

"If you do it a few more times, it will still be the same. Think about it for yourself, what direction was the key in when it was in the deceased's trouser pocket?"

"What direction?"

Hattori Heiji didn't understand Baidi's reasoning. He couldn't help but recall the scene when the key fell out of the deceased's trouser pocket. His pupils suddenly shrank and he immediately turned to look at Baidi.

As for the other people in the study, they had already begun She couldn't understand the reasoning exchange between the two, and there was a trace of confusion in her eyes.

Seeing this scene, Yang Nai admired Bai Di even more. A person can't help but achieve outstanding achievements in music, and also in reasoning. Shangya is better than ordinary detectives, and Baidi has always had a good image and a perfect personality, which naturally made a deeper impression in Yangono's heart.

Even Yukino who happened to hear Baidi's words last time. After learning about the gentle but extremely hypocritical mask on Bai Di's face,

Xueno couldn't help but feel a little stir in her heart as Bai Di's reasoning ability showed. She sighed.

It seemed that although her sister Yangno had always been evil and often teased others, she estimated that this time, Yangno's heart would really be completely attracted by ordinary girls. Idol likes handsome boys, but Yangno is different. She is only curious about others.

However, when she is curious about others, Yangno will energy to explore and explore other people's secrets. Generally, almost all teenagers of her age experience this. They are all ordinary, so naturally they cannot attract her.

However, Bai Di is different. Others know very little about Bai Di's past. In addition, Bai Di's talent, outstanding musical talent and strength are overwhelming. The reasoning ability of a high school detective, his handsome appearance, his dazzling silver hair that shows a hint of vicissitudes of life, and his kind-hearted and perfect personality are enough to make any girl fall for her, even Yangno. In front of Bai Emperor, she was just a curious girl.

"When the key fell out of the trouser pocket, in which direction did it go? Do you guys still remember?"

Baidi's clear and charming voice came to Yangno's ears, and Yangno's eyes couldn't help but a flash of light.

Hearing Baidi's words, Hattori Heiji and others couldn't help but recall that the key had been taken from the deceased's trouser pocket.

Suddenly, Hattori Heiji's body trembled and he looked at Baidi in shock. Baidi nodded and picked up the bunch of keys with a calm expression, adjusting how the keys would be put in in front of everyone. explained,

"That's right, even if the key does get into the innermost or side pocket, it should only be the key ring. Because in a narrow double-layer pocket, it is absolutely impossible for key rings and keys to be folded into a figure-7 shape.

But in fact, the key and the key ring were not. This means that the murderer put the key into the double pocket of the deceased from the beginning."

"So, tell me, how do you explain the fishing line found in the room?"

Hattori Heiji took the ball of fishing line in his hand and asked Baidi

"It was just a trap set up by the murderer to pin the blame on this old gentleman. I also found several skeins of fishing line, you see."

Having said this, Bai Di paused slightly, stretched out his hand and took out a few balls of fishing line, turned to look at the crowd and continued,

"However, for some reason, after being framed, the old gentleman not only did not speak out, but also protected the murderer, right, old gentleman?"

Bai Di showed a faint smile to the old gentleman, no more arrogant, no less confident.

The old man did not answer, of course Bai Di did not expect him to answer.

However, Officer Mu Mu and others did not Bai Di and others The old gentleman acted so calmly, and they all looked at him in surprise, wondering why he wanted to protect the murderer.

"But this is a completely sealed secret room. Is it possible that you want to say that the deceased committed suicide?"

Hattori Heiji couldn't help but ask when he saw that Bai Di had not told who the murderer was.

"Of course not," Bai Di shook his head slightly and continued,

"The killer left clues to his true crime methods at the scene, but most of us didn't notice."

"True crime modus operandi?"Officer Mu Mu said in surprise.

Bai Di nodded and said,

"You should still remember that when the deceased was found, opera music was playing in the study, and there was a high pile of books in front of the deceased. These are clues."

Hearing this, everyone couldn't help but concentrate and listen carefully. Even Yukinoshita Yukino, who was wary of Bai Di, couldn't help but calm down and listened to Bai Di's reasoning with all his concentration.

"Opera music is played, the purpose of which is to prepare the murderer to silence the screams that the deceased may make when the poison needle is inserted. As for the pile of books, it was to prevent the deceased from being discovered by the painful expression that might occur when a poisonous needle was pierced into the neck."

"Hahaha..."

Hattori Heiji burst out laughing, interrupting Baidi's reasoning, and looked at Baidi with an expression of disbelief,

"How is this possible? Whose eyes and ears did the murderer do this to cover his eyes? Bai Di sighed, glanced at the man imperceptibly, and explained,

"Hattori Heiji, you are the guests invited to the study."

0·····Asking for flowers··········

"What did you say?"

"Any guests who might come to the study at that time, if they noticed this, would ruin the murderer's plan."

"So, is it?"

Not only Hattori Heiji, but also the Yukinoshita couple and Mouri Kogoro suddenly turned their heads to look at that person.

"Yes, the murderer is you, Mrs. Tsujimura."

Bai Di suddenly turned around, looked at Mrs. Tsujimura standing in the crowd, and said coldly

"Madam, how is it possible?"

"Madam killed the master?"

"It turned out to be Mrs. Tsujimura"

"..."

Everyone looked at Mrs. Tsujimura standing in the crowd in shock, but Mrs. Tsujimura was slightly startled when she heard Bai Di's words, and then immediately returned to her normal appearance.

"Then when we first entered the study, the deceased was actually still alive?"

Moori Kogoro asked Baidi.

Baidi nodded and said calmly,

"That's right, because at first Mrs. Dimension only used some kind of drug to anesthetize Mr. Tsujimura and make him fall asleep. When Mrs. Tsujimura woke up the deceased, she took the opportunity to pierce the neck of the deceased with a fine needle dipped in poison, killing the deceased.

0..............

Because the hypnotic drug is very powerful and the concentration on the fine needle is also extremely poisonous, naturally no one will notice this. At this point, I have to say one more thing, Mrs. Tsujimura's courage is really extraordinary, she was able to come up with this method to kill Mr. Tsujimura in public."

At the end, Bai Di's eyes flashed with a faint smile that seemed to be mocking and appreciative.

"However, if the hypnotic drugs on the deceased were discovered, wouldn't the plan be exposed?"

Officer Memu asked puzzledly.

"No, it won't be exposed." Hattori Heiji shook his head, looked at Bai Di appreciatively, and explained quietly,

"Because we have always believed that the deceased was killed before we entered the study. According to what you said, the murderer stabbed the deceased's neck with a poisonous needle and made him fall asleep without resistance.

In other words, the murderer deliberately found the detective here and took advantage of the blind spot where they believed the murderer would not kill in front of him to carry out psychological secret room killings."

Having said this, Hattori Heiji's face looked a little ugly, because he was also the detective who was used and was almost misled by the murderer. Naturally, he was in a bad mood. He looked at Mrs. Tsujimura coldly and said

"And none of us will notice, is that what you mean, Bai Di?"

Bai Di saw the look on his face when Hattori Heiji looked at him, and couldn't help but smile lightly and agreed.

However, Hattori Heiji looked at Bai Di and asked him for his evidence.

"As for the evidence, you must know that Mrs. Tsujimura did not take out the poisonous needle at that time. Bai Di reached out and picked up the key, opened the middle floor to let everyone take a look, and explained,

"Yes, Mrs. Tsujimura did take out the poisonous needle without anyone noticing. Because the poisonous needle is hidden in the middle layer with the key."

"On the key?"

Mouri Kogoro said in surprise.

Bai Di nodded, and then looked at Mrs. Tsujimura,

"The key ring on Mrs. Tsujimura's body and the key ring on the deceased's body have the same design and shape. This means that the key ring on Mrs. Tsujimura's body can be opened and the poisonous needle can be hidden like the key ring on the deceased's body in my hand.

Okay, Mrs. Tsujimura, can you take out your key ring and let us all take a look at the door?"_
