Ke Xue: I picked up a bottle of sherry at the beginning.

"Excuse me, Officer Megure," Hattori Heiji said with a smile, holding a needle, "could you please play the role of the deceased?"

"Oh..." Inspector Megure looked at Hattori Heiji with a confused expression.

"At the time of the crime, all the windows of this study were locked from the inside, and the only door that could be used for entry and exit was also locked with a key." Hattori smiled confidently, "This makes it a closed-room murder case with no gaps, but this room that seems to be a completely closed room actually has a gap!" Hattori's dark cheeks seemed to shine with confidence.

"Gap?" Kogoro Mouri asked after a moment of surprise.

"That's right, it's the gap under the door!" Hattori pointed under the door.

"You're not going to say that the murderer threw the key to the study into the victim's pocket through this gap, are you?" Kogoro Mouri said with disdain, squinting his eyes.

"You're right, of course it's possible!" Hattori's words were earth-shattering. "As long as I have the tape and what I just found..." He pulled a roll of fishing line from his pocket. "This fishing line used to tie iron needles will do."

"Fishing line?" Kogoro Mouri was stunned again.

"That's right, the murderer is like this..." Hattori Heiji came to Inspector Megure, who was playing the role of the deceased, holding an iron needle. "First, he stabbed the victim's neck with a poison needle, killing him, and then snatched the victim's keys. Then, he pulled out the fishing line tied to the iron needle, and then used the other end of the fishing line tied to the iron needle to stick to the tape to fix it. Then, he stuffed the end tied to the iron needle into the victim's pocket and let the fishing line pass through the middle. Finally, he made the victim sit on a chair... and made the deceased pose with his hands supporting his cheeks when the body was found." Hattori said as he helped Inspector Megure sit on the chair, then slowly pulled the fishing line to the door, closed the door, and pulled the line...

Amidst everyone's stunned expressions, the key actually slowly moved from outside the door into Inspector Megure's pocket!

"In this way, a complete secret room is formed!" Hattori Heiji opened the door and smiled confidently.

"Wow... so awesome!" Everyone stared at Hattori Heiji's reasoning, stunned for a moment.

"No... you're wrong..." A voice came from the door. Everyone, including Hattori, turned their heads and saw Kudo Shinichi leaning against the door, looking haggard.

Ran heard Kudo Shinichi's voice and quickly ran upstairs: "Shinichi, why are you here?"

Kudo Shinichi acted cool and said, "Because the case is calling me."

Xiaolan was speechless and said, "So, the case called you and you responded. I called you and you didn't move. Am I right?"

Kudo Shinichi was embarrassed and quickly explained: "No, Xiaolan, listen to me..."

Hattori Heiji said: "Let's flirt with each other at another time. Let me ask you, Kudo Shinichi, where did I go wrong?"

Kudo Shinichi said: "The method you mentioned is impossible to complete in practice.

"What?" Inspector Megure was also surprised, "But...but...the experiment just now was clearly successful!"

"Take a closer look." Kudo Shinichi turned his head and glanced at Hattori and said lightly.

"Look then!" Hattori opened Inspector Megure's pocket in anger.

"Ding dong!"

With a slight sound, everyone's eyes suddenly widened, and Hattori even let out a slight cry.

"How...how is this possible?" Hattori stared at the key that had fallen to the ground in amazement. "I clearly...had already threaded the fishing line through the double pockets!"

"That's because Inspector Megure is sitting down." Kudo Shinichi picked up the key and gently opened the compartment in the middle of the key.

"When people sit, wrinkles will appear between their clothes, which will block the key from entering. In addition, the deceased was fatter than Inspector Megure, and his pants were probably tighter, so the key was pulled out before it could enter the double pocket!" Shinichi played with the key chain in his hand and slowly walked to the bookshelf.

"Also, doesn't this photo look familiar to you?" Kudo Shinichi walked to the bookshelf and gently flipped through a photo.

Hattori Heiji felt as if he had been hit hard on the head, and his mind was suddenly shaken: "The fishing line you found in the old man's room is everywhere in this house."

Kudo Shinichi pulled a handful of fishing line from his pocket. "At least I found five or six rolls of this stuff."

Hattori Heiji said in frustration: "Kudo Shinichi, then tell me, who is the murderer?"

Kudo Shinichi said: "The books piled on the desk are just to cover up the hideous expression the victim may have left before his death, and the opera is also to cover up the possible screams. This is why the murderer did not use the classical music that the deceased often listened to, but the higher-pitched Italian opera." Kudo Shinichi put down the photo in his hand and picked up the key chain again.

"Then, if you do this, why do you have to hide it so much?" Unconsciously, the original provocation in Hattori's words had disappeared.

"Of course..." Kudo Shinichi turned his head and looked at Hattori Heiji with a faint smile, "Hattori Heiji you!"

"What?" Hattori Heiji was shocked.

"Of course, there are other people who came into the room with him." Kudo Shinichi looked around and finally stopped his gaze on a person.

"If that's the case..." Hattori's body trembled and his eyes widened suddenly.

"The only ones who can get close to the victim are those present here, and the only one who can kill the victim at the closest distance is Mrs. Tatsumura!"

"It's actually Mrs. Damun!" Everyone looked at Mrs. Damun in surprise.

"So," Maori Kogoro finally reacted, "the victim was still alive when we entered the room?"

"That's right." Kudo Shinichi nodded. "In fact, when we went in, the diplomat was just put to sleep by his wife using a powerful sleeping pill."

"But," Inspector Megure looked at Kudo Shinichi doubtfully, "Once the body is sent for examination, this method will..."

"No!" A voice came from the side, startling everyone.

Hattori Heiji slowly stood up, the brim of his cap obscuring his face. "The murderer is trying to trick us into thinking the victim died before we entered the room. A poison needle, naturally, could have contained an anesthetic. Furthermore, she specifically brought the detective here to create the illusion that the murderer wouldn't dare kill in front of the detective."

"So the murderer is you, Mrs. Tatsumura," asked Inspector Megure.

"Yes, I am the murderer," Mrs. Tatsumura replied.

However, events took another surprising turn.

"You're wrong, Kudo Shinichi. Mrs. Tatsumura is not the murderer," Shiraizumi said calmly. "Mrs. Tatsumura, your deliberate attempt to cover up by bringing in the real culprit won't work in front of me."

Mrs. Dacun was shocked and lowered her head without saying a word.

"What did you say?" Kudo Shinichi was shocked. "My reasoning is flawless, how could there be a problem?"

"The diplomat was stabbed by the poison needle and died instantly. This shows that the poison in the diplomat is highly toxic. Even a very low dose can kill an adult, and the toxin has a paralyzing effect. After identification by the Identification Department, it was determined that the poison the diplomat said he was infected with was tetrodotoxin." Bai Quanyi looked at the police officer from the Identification Department.

The Identification Officer replied, "That's right. The diplomat's poisoning was initially diagnosed as tetrodotoxin."

Bai Quanyi said: "Tetrodotoxin is a controlled drug. It is almost impossible for ordinary people to buy this highly toxic substance. Madam Dacun, there is no way to buy this highly toxic substance."

Bai Quanyi looked at Miss Sachiko and said, "Miss Sachiko, I have just asked my colleagues to investigate your information. You used to work at the Baijiu Pharmaceutical Research Institute. Am I right?"

Miss Sachiko hesitated for a moment, then nodded and said, "Yes."

Shiraizumi said, "Among all people, only Ms. Sachiko has the chance to obtain tetrodotoxin."

"So, the real murderer is Miss Sachiko!" Inspector Megure was shocked. This incident was full of twists and turns.

Hattori Heiji couldn't believe it. Even Kudo Shinichi lost to Shiraizumi Masu.

Shiraizumi Masu looked at Kudo Shinichi and Hattori Heiji, and it was quite amusing to see the two famous detectives' expressions of disbelief after being slapped in the face by him.

41. Xiaolan is completely disappointed with Kudo Shinichi

Kudo Shinichi said unconvincedly: "Shiraizumi Masu, why don't you tell me Miss Sachiko's motive for murder? Miss Sachiko, why did you kill your own father-in-law?"

"As for the motive for the murder," Bai Quanyi picked up the photo on the table, "it should be in this photo, right?"

Hattori Heiji's eyes lit up, and he suddenly said, "Could it be that..."

"That's right, Miss Sachiko must be Mrs. Tatsumura's daughter!"

"Really...really?" Inspector Megure stared at the photo in his hand, and was stunned when he saw Mrs. Tatsumura from decades ago, whose only difference from Sachiko today was her hair color.

"That's right." Mrs. Tatsumura stood up in silence. "Sachiko is my daughter!"

Sachiko's cold expression actually contained a hint of relief as she said, "I've known about this for a long time."

Mr. Guishan's face was full of surprise: "So... Sachiko... you... are actually my sister with the same mother but different husband!"

Shiraizumi Masu said, "Miss Sachiko knew that Mr. Yoshiki was her biological brother, yet she still approached him and had an incestuous relationship with him. Her goal was probably revenge. Through Mr. Yoshiki, she approached the diplomat. She wanted revenge on the diplomat who killed her father and took away her mother!"

Mrs. Tatsumura said, "I never imagined at first that Sachiko approached Takayoshi with the intention of killing my husband. By the time I found out, it was too late. So, I tried to find a way to take the blame for my daughter and deliberately set up this trap to lure the famous detective Maori Kogoro."

After listening to Bai Quanyi's reasoning, Xiaolan was full of admiration for Bai Quanyi.

Bai Jun is really perfect, even his reasoning ability is better than Shinichi's.

"How could this be? I lost to Shiraizumi Masu. I can't accept it. I'm so unwilling to accept it..." The only thing Shinichi Kudo was proud of was his reasoning ability, but he didn't expect to lose to Shiraizumi Masu.

"Hey, hey... Shinichi, there's no need. We lost to Shiraizumi Masu this time, we can just win back next time." Hattori Heiji transferred his competitor from Kudo Shinichi to Shiraizumi Masu.

Mao Lilan came over and said to Kudo Shinichi: "Shinichi, now, can you explain to me why you left without saying goodbye and why you disappeared for so long?"

Kudo Shinichi's heart skipped a beat. He had a feeling that he would soon turn back into Edogawa Conan. Kudo Shinichi pushed Mao Lilan away and said, "Ran, please get out of the way. I don't have time to care about you now. Give me some more time."

After saying that, Kudo Shinichi immediately rushed out of the room.

"Ah!" Xiaolan staggered and almost fell.

Seeing this, Bai Quanyi immediately stepped forward and supported Xiaolan.

"Xiaolan, are you okay?"

"I'm fine, thank you, Bai-kun."

"Shinichi has gone too far. How could he bully you like this? It's too much. Next time, I will definitely teach him a lesson."

"Forget it, Bai Jun, I'm used to it. Shinichi, you didn't have me in your heart from the beginning. It was my wishful thinking and self-indulgent thoughts. I should have understood it long ago." Xiaolan said sadly. Xiaolan felt that she was really cheap. She tried her best to please Kudo Shinichi, but got nothing in return.

"In that case, just ignore Kudo Shinichi. A good girl like you shouldn't have to endure this kind of hurt."

Baiquan Yi said indignantly.

Maori Kogoro couldn't help but say something more, "Xiaolan, I told you a long time ago... Don't pay attention to people like Kudo Shinichi, you just won't listen to me..."

Xiaolan said: "Dad, I know I was wrong."

Maori Kogoro said, "That's right. When Kudo Shinichi was here, my detective agency couldn't keep going. Fortunately, he's been gone for a while now, so my commissions have gradually increased."

Xiaolan said, "I'm sorry, Dad."

Maori Kogoro said: "Let's go, Xiaolan, let's go back."

Inspector Megure also said: "Brother Izumi, it's time to pack up."

Bai Quanyi chuckled and said to Xiaolan: "Goodbye, Xiaolan."

Xiaolan nodded and said, "Well, Bai Jun, goodbye."

Shiraizumi Masu was about to drive back to the Metropolitan Police Department when Hattori Heiji chased after him and shouted, "Officer Shirai, wait for me, I have something to tell you..."

Bai Quanyi rolled down the window and asked, "Hattori-kun, what do you want to say?"

Hattori Heiji said: "I want to be friends with you. I like to be friends with people like you who have strong reasoning ability."

Bai Quanyi smiled and said, "Be friends with me...sure."

(Hattori Heiji has a super cute childhood sweetheart and a super beautiful mommy, so Shiraizumi Mashi naturally wouldn't refuse to make friends with Hattori Heiji.)

Hattori Heiji said: "Great. From now on we will be good brothers!"

Hattori Heiji took out his cell phone and exchanged numbers with Shiraizumi Masu.

Shiraizumi Masu said, "See you next time, Hattori-kun."

Hattori Heiji said: "I will find a chance to invite you to visit Osaka, don't refuse."

Bai Quanyi stretched his hand out of the car window, made an OK gesture, and drove away.

Hattori Heiji secretly made up his mind: "Just wait, Shiraizumi Masaru, I will definitely beat you next time!"

42. Kiss within 5 seconds of meeting

In the afternoon sun, Shiraizumi Masu stood at the door of Kudo's house, waiting for Mrs. Kudo.

Mrs. Kudo appeared in front of Shiraizumi Yi wearing a green dress, a pair of gray high heels and a beige round hat.

She is such a young and beautiful lady. It is really unreasonable for Mrs. Kudo to have such beauty at her age.

"Mrs. Kudo, you're here."

"Didn't I tell you to call me sister?"

"Sister Yukiko, you're here."

"Well, I'm here, Bai-kun."

Yukiko Kudo has a faint smile that makes people feel like spring breeze.

"Sister Yukiko, what do you think you should do?"

"What do you want me to do?"

Yukiko asked in confusion, her eyes twinkling.

"Kiss me?"

"what?"
