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

“That’s right.” Bai Quanyi nodded, “This performance is exactly the symptom of poison suffocation. ”

The dizzy Conan also agreed with this view.

Officer Twilight touched his chin: “It is worth mentioning that all the windows in the study are locked from the inside of the room, and it is impossible to get out of the room… So, this door is the only entrance…” Saying that, Officer Twilight turned to look at Mrs. Tatsuma, “Madame, there should be several keys in this study, right?” ”

“No,” Mrs. Tatsumura shook her head, “there are only two keys to the study. Saying that, he reached out and took out a key with a key ring from the bag he was carrying, “One is this one in my hand, and the other is on my husband.” ”

“On your husband?” Officer Twilight was taken aback.

“Well,” Mrs. Tsujimura nodded, “my husband is used to putting it in his trouser pocket. ”

“Is that so? Then I’ll go and make sure. Officer Twilight turned and walked over to Mr. Tatsuma’s body.

Officer Twilight digged his hand into the corpse’s trouser pocket and fumbled, “Really, stuffed bulging.” With that, Officer Twilight pulled out Tsujimura’s pants pocket.

“Double pockets…” Izumi froze slightly.

Officer Twilight took out the bulging thing, which was exactly the same key as the key in the hand of Damura Gongjiang!

“How… How can it be? Officer Twilight exclaimed in shock.

“This… This is the so-called murder in the back room? Maori Kogoro was flabbergasted.

Conan only felt hot and drowsy, and even made a buzzing sound between his ears from time to time. “Now… It’s a little bad…” Huge beads of sweat ran down Conan’s forehead, and even his sideburns were already soaked.

“Are you all right, Conan?” Xiao Lan looked at Conan with concern and touched his head, “It’s so hot!” ”

“I’m okay, Sister Xiaolan.” Conan squeezed a smile out of his face.

“Don’t be stubborn, I’ll take you outside to rest.” Xiaolan picked up Conan and took him downstairs to the living room to lie down.

After the two left, everyone focused their attention on the deceased again.

“This… This can’t be, right…? Maori Kogoro, who had been pondering for a while, muttered.

Hattori Heiji looked at Maori Kogoro’s expression, his eyes narrowed slightly, and he sneered inwardly. “Sure enough, the reasoning of this uncle who was recently published in the press is not his own reasoning at all, it is Kudo Shinichi’s!” The figure in the blue suit once again appeared in Hattori’s mind, “All the cases were solved by him, this mediocre uncle secretly contacted Kudo to seek his help and solve the case, this time it is estimated that it is also the same, very good, who will solve this secret room murder incident first, let’s see, Kudo Shinichi!” A confident glint flashed in Hattori’s eyes.

“And Bai Quanyi! I will prove myself better than you! Hattori glanced at the indifferent Shiraizumi. Obviously, Bai Quanyi didn’t care about him.

“The time of the crime should be between three and a half to four o’clock.” Hattori stood up and looked at everyone, “In short, the alibi of the person who may have committed the crime during this time should be found out as soon as possible!” ”

“Brother Quanyi, what do you think?” Officer Twilight looked at Bai Quanyi and asked Bai Quanyi’s opinion. Although Hattori’s reasoning sounds reasonable, after all, Shiraizumi is the policeman.

“Just do as this African friend says.” Bai Quanyi nodded.

“I’m not African, I’m Heiji Hattori!” Hattori went crazy, and when he arrived in Tokyo, everyone thought he was from Africa.

“So, Mr. Koike, the housekeeper, has been chatting with neighbors nearby at the gate between three and four o’clock in the afternoon, right?” Officer Twilight began to ask for the alibi.

“Hmm.” Fumio Koike was stunned for a moment and nodded.

“Mr. Kizen and Miss Sachiko and the two of them also arrived before Mrs. Tatsumura returned home, isn’t it?”

“Yes, it is.” Fumio Koike replied.

“So where are you when Mr. Koike arrives at the gate and picks up Mrs. Damura?”

“We went to my dad’s study, but the door was locked. He didn’t answer, so we quickly came downstairs. Mr. Kizen said.

“As soon as I came down, I was at the gate. Met with my mother. Miss Sachiko said.

“Then, Mr. Liguang came here, it will be after 2 o’clock.”

“yes. I finally got here. Ah Xun was locked up in the study, and Gongjiang went out again. I didn’t think it was interesting, so I stayed at home and watched TV. Mr. Liguang said.

“So, when did Mrs. Tatsumura go out.”

“I went out before one o’clock.” Mrs. Tatsumura said.

After Hattori Heiji listened to everyone’s alibi, he had already locked up the prisoner.

“The real murderer is you!” Hattori Heiji turned his head and pointed his finger directly at the old man, Tatsumura Toshimitsu!

“What?” The Twilight Police Department was incredulous, “Is there any basis?” ”

“I’m sorry, Officer Twilight,” Hattori said with a smile as he held a needle, “could I please play the deceased?” ”

“Oh…” Officer Twilight looked at Hattori Heiji with a blank expression.

“At the time of the crime, all the windows of this study were locked from the inside, and the only door that could enter and exit was also locked by a key.” Hattori smiled confidently, “In this way, a murder case with no gaps has been formed, but there is still a gap in this room that seems to be a completely secret room!” Hattori’s dark cheeks seemed to glow with confidence.

“Gap?” Maori Kogoro asked stunned.

“That’s right, it’s the gap under that door!” Hattori pointed under the door.

“Shouldn’t you say that the murderer threw the key to this study into the victim’s pocket from under this gap?” Maori Kogoro squinted his eyes and said with disdain.

“You’re right, of course it’s possible!” Hattori’s words were groundbreaking, “As long as there is tape and what I just found…” he said, and he took out a roll of fishing line from his pocket, “This fishing line is used to tie iron needles.” ”

“Fishing line?” Maori Kogoro was stunned again.

“That’s right, that’s what the murderer looks like,” Hattori Heiji came to Officer Twilight, who was playing the deceased, with an iron needle, “first stabbed a poison needle into the victim’s neck, killed him, and then snatched the victim’s key.” Then, he pulled out the fishing line with the iron needle tied, and then glued the other end of the iron needle to the tape to fix it, and then stuffed one end of the iron needle into the victim’s pocket and let the fishing line pass through the middle. Finally, let the victim sit on the chair… Have the deceased pose with his hand supporting his cheek when the body is found. Hattori said and helped Officer Twilight to sit on the chair, then pulled the fishing line slowly to the door, closed the door, and pulled the line….

Under everyone’s stunned expressions, the key actually slowly entered the pocket of Officer Twilight from outside the door!

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

“Well… That’s awesome! Everyone looked at Hattori Heiji’s reasoning stunned, and was stunned for a while.

“No… You’re wrong…” A voice came from the doorway. Everyone, including Hattori, turned their heads sharply, and saw Kudo Shinichi leaning against the door, full of haggardness.

Xiaoran heard Kudo Shinichi’s voice and quickly ran upstairs: “Shinichi, why are you here?” ”

Kudo Shinichi played a handsome trick and said, “Because the case is calling me.” ”

Xiaolan had a black line and said, “So, the case calls you, and you respond.” I call you and you don’t move. Am I right? ”

Kudo Shinichi was embarrassed, and quickly explained: “No, Xiaoran, you listen to me…”

Hattori Heiji said: “Flirting for another time, I ask you, Kudo Shinichi, where am I wrong!” ”

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

“What?” Officer Twilight was also taken aback, “But… But…… The experiment just now was clearly successful! ”

“You take a closer look.” Kudo Shinichi glanced back at Hattori and said lightly.

“Just watch!” Hattori gambled and pulled open Officer Twilight’s pocket.

“Ding-dong!”

With a soft sound, everyone’s eyes suddenly widened, and Hattori exhaled softly.

“This… How is this possible? Hattori looked dumbfounded at the key that had fallen into the ground, “I know… It’s all already getting the fishing line through the double pockets! ”

“That’s because Officer Twilight is sitting.” Kudo Shinichi picked up the key and gently opened the mezzanine in the middle of the key.

“If a person is sitting, there will be wrinkles between the clothes, which will block the entry of the key. In addition, the deceased was fatter than Officer Twilight, and his pants were tighter, so before the key could enter the double pocket, the connected fishing line was withdrawn! The new one played with the key chain in his hand and slowly walked to the bookshelf.

“And, don’t you feel familiar with this photo?” Kudo Shinichi walked to the bookshelf and gently flipped through a photo.

As if someone had hit him the head, his mind suddenly shook: “The fishing line you found in that old gentleman’s room is everywhere in this house.” ”

Kudo Shinichi pulled a handful of fishing line out of his pocket: “At least I found five or six rolls like this.” ”

Hattori Heiji said deflatedly: “Kudo Shinichi, then tell me, who is the murderer?” ”

Kudo Shinichi said: “The books piled up in front of the desk are only to hide the hideous expression that the victim may have left before death, and the opera is also played to cover up the possible screams, which is why the murderer did not use classical music that the deceased often listened to, but Italian opera with a higher voice.” Kudo Shinichi put down the photo in his hand and picked up the key chain again.

“So, is there any need to be so secretive if you do this?” Unconsciously, in Hattori’s words, the original provocation had disappeared.

“Of course it is…” Kudo Shinichi turned his head, looked at Hattori Heiji, and smiled slightly, “Hattori Heiji, you!” ”

“What?” Hattori Heiji was taken aback.

“And, of course, the others who entered the house together.” Kudo Shinichi looked around and finally stopped his gaze on a person.

“So…” Hattori’s figure trembled, and his eyes widened sharply.

“The only person who can get close to the victim is everyone here, and the person who can kill the victim at the closest distance is Mrs. Tatsumun!”

“It turned out to be – Mrs. Tatsumun!” Everyone looked at Mrs. Tatsumun in amazement.

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

“That’s right.” Kudo nodded, “Actually, when we went in, the diplomat was just put to sleep by Madame with a powerful sleeping pill. ”

“However,” Officer Twilight looked at Shinichi Kudo suspiciously, “once the body is sent for examination, this method will not be…”

“Nope!” A voice came from the side, which startled everyone suddenly.

Hattori Heiji slowly stood up, the brim of his cap, covering his face, “The murderer will make us mistakenly think that the victim died before we entered the room, and after being stabbed to death by a poisonous needle, it can naturally carry anesthesia.” Moreover, she deliberately found the detective here in order to give people the illusion that the murderer did not dare to kill in front of the detective. ”

“So, the murderer is you, Mrs. Tatsuma.” Twilight asked.

“Yes, I am the murderer.” Mrs. Tatsumura replied.

However, another startling reversal of events took a striking turn.

“You’re wrong, Kudo Shinichi, Mrs. Tatsumura is not the murderer.” Bai Quanyi said lightly. “Mrs. Tatsumun, you are planning to bring real prisoner cover, and it will not work in front of me.”

Mrs. Tatsumun’s body was shocked, and she lowered her head without speaking.

“What do you say!” Kudo Shinichi was shocked, “My reasoning is seamless, where is the problem?” ”

“The diplomat was pricked by a poison needle and died immediately, which shows that the poison in the diplomat is highly toxic. Very low amounts can cause death in an adult, and the toxin has a paralyzing effect. According to the identification department, the poison that diplomats said was tetrodotoxin. Bai Quanyi looked at the officer of the identification section.

The officer of the identification section replied: “Yes, the poisoning of the diplomat was preliminarily identified as tetrodotoxin. ”

Bai Quanyi said: “Tetrodotoxin is a controlled drug, and it is almost impossible for ordinary people to buy this highly toxic substance. Mrs. Tatsumun, there is no way to buy this highly toxic substance. ”

Shiraizumi looked at Miss Sachiko and said, “Miss Sachiko, I have just commissioned a colleague to investigate your information. You worked at the Hakuhato Pharmaceutical Research Institute, I’m right. ”

Miss Sachiko hesitated, then nodded and said, “Yes.” ”

Shiraizumi said, “Of all the people, only Miss Sachiko has a chance to get tetrodotoxin. ”

“In this way, the real murderer turned out to be Miss Sachiko!” The Twilight Police Department was shocked, this incident was really a twist and turn.

Hattori Heiji was in disbelief, and even Kudo Shinichi lost to Shiraizumi.

Shiraizumi looked at Shinichi Kudo and Heiji Hattori, and it was really interesting to see how the two detectives looked unacceptable after being punched in the face by him.
