Heiji Hattori first agreed with Kogoro Mori, but then he said, "Of course it's possible, as long as you have the tape and the fishing line I just found to tie the poison needle!" ”

With a smug face, Hattori Heiji took out the roll of fishing line he had found in the Japanese room from his trouser pocket and looked down at Mori Kogoro. Although in terms of height, he is about the same as Mori Kogoro, but psychologically, Hattori Heiji feels that he can look at Hattori Heiji with a downward gaze.

"Fishing line?" Mori Kogoro looked at the fishing line in Hattori's hand and didn't know what it was for.

Kei Suzuki looked at Mrs. Tsujimura, and he could sense that Mrs. Tsujimura was very nervous when Heiji Hattori said that he already knew who the murderer was, and at the same time knew the methods used by the murderer. However, when Hattori Heiji took out the fishing line from his trouser pocket, Mrs. Tsujimura was completely relaxed, and at the same time, the corners of her mouth were curled, and she seemed to be a little proud.

Kei Suzuki had been observing Mrs. Tsujimura all along, and when he found out that Mrs. Tsujimura was behaving like this, he knew that Heiji Hattori must have made a mistake. However, this woman seems to have been carefully planned before committing the murder, and Kei Suzuki did not find anything valuable from the murder scene at all.

Even if Kei Suzuki could detect the existence of murderous aura from Mrs. Tsujimura's body, this could not be used as evidence for the arrest, and the court would not accept Kei Suzuki's statement.

So although Kei Suzuki knew that Hattori Heiji was wrong, he just looked at it like this and didn't say anything. He wondered if Mrs. Tsujimura would get carried away and reveal any clues after she found out that Hattori Heiji was wrong.

The policeman was lying on the carpet, and Hattori Heiji found a needle and dangled it in front of his eyes, making his cold sweat flow out, for fear that Hattori Heiji would also prick him.

"This is what the murderer looked like, first stabbed the victim in the neck with a poisonous needle, killed him, and then took away the victim's key. The killer then tied the needle to one end of the line, and the other piece was taped to the inside of the keychain. The killer then threaded an iron needle through the victim's trouser pocket. ”

Speaking of this, he helped the policeman lying on the ground, asked him to sit on a chair, and posed that when they found the deceased, the deceased had a posture of holding his face with a pestle, pulled the fishing line back, and said as he retreated: "Put the deceased in this posture again, and walk out of the door, and you can draw the fishing line outside through the crack in the door." Close the door again and lock it up. Finally, by pulling the fishing line, you can pull the key under the crack in the door and into the study. From the ground to the table, and then to the inside of the deceased's trouser pocket. ”

When Hattori Heiji said this, the policeman who played the deceased was surprised to find that the key was really pulled into his pocket, as Hattori Heiji expected.

Maori Kogoro also shouted in surprise next to him: "It's really in!" ”

Hearing Mori Kogoro's voice, Hattori Heiji smiled and continued, "Then the murderer only needs to pull hard, and he can pull out the fishing line." As long as the fishing line is put away, the evidence is gone, and a perfect chamber is formed. ”

Maori Kogoro swallowed his saliva and said with difficulty: "It seems to be the case!" ”

The other people in the room all agreed with Hattori Heiji's idea when they saw Mori Kogoro, and they all looked in agreement. However, Suzuki Kai soon discovered the flaw in the middle, he looked at the smug Hattori Heiji, coughed and said, "That, Hattori-kun, I have a question I want to ask you!" ”

"What's the matter?" For Kei Suzuki, Hattori Heiji is quite unaccustomed to it, perhaps because Kei Suzuki said that he is not like his father. So for Suzuki Kai's words, Hattori Heiji said angrily: "Do you want to say who the murderer is?" I'll say it right away! ”

Kei Suzuki was unimpressed by Hattori's attitude, he shook his head and touched his subordinate's pants and took out the key. Then he asked, "When we found the key in the deceased's trouser pocket, wasn't it stuffed in the double-flush pocket, but I don't think you can get the key in this way, and it came out when you touched it." ”

Hattori's sweat came out at once, and Kei Suzuki's move immediately overturned all his inferences just now. According to his reasoning, if the murderer wanted to kill someone, it would take at least 5 or 6 minutes. And during the time when the murder occurred, only the 78-year-old man Toshimitsu Tsujimura had this time.

Because at 4 o'clock, Mrs. Tsujimura was with them, and there was no time to commit the crime. And it's not impossible for the housekeeper Koike, who has been chatting with the neighbors and greeting him outside the door. Although Takazen Tsujimura and his girlfriend Sachiko Katsuragi also went to the second floor, they only went up to the second floor for just over 1 minute, and it was impossible for them to kill anyone.

But Suzuki Kai's move immediately made Hattori Heiji dumbfounded, if the old man is not the murderer, then who is the murderer?

Hattori Heiji said in disbelief: "How is it possible, I obviously passed the needle through the double pocket." ”

Keishi Suzuki wanted to speak, but Xiaolan suddenly opened the door and came in, she looked into the study at the door and shouted, "Conan, are you here?" ”

Seeing Suzuki Kai's gaze turned, Xiaolan said, "Brother Qi, have you seen Conan?" ”

Suzuki Kai shook her head, and just as Xiaolan wanted to leave, a voice that haunted her suddenly came from behind her and said, "Don't you know that the fabrics are very soft?" If you want to keep the key in a drawer, it's possible. But the deceased was sitting at the time, and the fabric in his trouser pocket must have been wrinkled. In this case, when you pull the line harder, you will only pull the line out, and it is impossible to carry the key into the double pocket. Because the folds in the trouser pockets have blocked the double pockets. And the deceased is so fat, this situation is even more obvious. ”

Xiaolan thought of what Hattori Heiji said in the detective agency, "Shinichi Kudo must be watching you somewhere." Seeing Kudo Shinichi appear, Xiaolan's face immediately turned red. He muttered, "Shinichi, Shinichi." ”

Kei Suzuki was also a little curious about the sudden appearance of Shinichi Kudo, wasn't it still Conan just now? Why did it suddenly come back? I remember that in my memory, Edogawa Conan, the Grim Reaper elementary schoolboy, has been a schoolboy for decades, and if he changed back, his nickname would not be "Grim Reaper Elementary Schoolboy".

Kei Suzuki shouted curiously: "Kudo Shinichi? ”

Kudo Shinichi looked at Kei Suzuki, nodded to him, and said, "Officer Suzuki, thank you for taking care of Conan recently!" ”

Hearing this, Kei Suzuki knew that this was the real Kudo Shinichi, not someone pretending, and the others didn't know that Kudo Shinichi was Conan. So he said "um".
