Hattori Heiji also looked back at Kudo Shinichi who was standing behind Xiaolan, leaning on the wall, and said secretly: "He is Kudo Shinichi?" ”

Although Hattori Heiji also thought that Kudo Shinichi's words were reasonable, he still refused to admit defeat and said, "This...... Chances are! ”

As soon as such words were spoken, Hattori Heiji scolded himself for being stupid, the probability of this was too low, so he quickly changed his words: "Ah, no." There is always a coincidence in ten times, right? ”

Suzuki Kai stopped Hattori from quibbling and said, "Hattori, okay, don't talk about it." In the case of the deceased being so fat, no matter how many times he tries, it is like this. ”

Kudo Shinichi also said: "Think about it, at that time, when the key was in the double pocket of the deceased, how did it be placed? ”

Since the key was taken out by Kei Suzuki, he thought for a while and said, "Well, it seems to be very neatly placed in the double pockets." ”

Kudo Shinichi's cold was not good at all, and when he said these few words, he was already covered in cold sweat. After hearing Kei Suzuki's words, Shinichi Kudo also said: "That's right, even if the key is really pulled into the double pocket, but in this case, only the keychain will be pulled into the pocket, and the key will definitely be left outside." ”

"This means that the murderer put the key in the deceased's double pocket at the beginning."

Keido Suzuki, "Wait, Kudo. You said that the murderer put the key in the deceased's pocket in the first place, so how did the murderer get out of this house? There are only a few people in the house, and if the murderer is the people in this house, then he won't have time to leave here at all? Could it be that the murderer had the key in his hand? ”

Speaking of the later time, Kei Suzuki's eyes looked at Mrs. Tsujimura. He has always thought that this Mrs. Tsujimura is the murderer, but there is no evidence, but now the appearance of Kudo Shinichi has increased Mrs. Tsujimura's suspicion a lot. And Kei Suzuki also heard it, and Mrs. Tsujimura's heartbeat began to speed up, and she seemed to be a little nervous.

Hattori Heiji hurriedly said, "Wait, how do you explain this fishing line I found in the Japanese room?" ”

Kudo Shinichi also stared at Mrs. Tsujimura and said, "That's just a trap set by the murderer, in order to blame the old Mr. Tsujimura Toshimitsu." Because according to your inference, at the time of the murder, only this old gentleman did not have enough alibi, and he was the most suspicious. ”

When he said this, Kudo Shinichi also took out a few rolls of fishing line and said, "I found 5 or 6 rolls of fishing line in different places in this house, maybe there are such things in places I haven't seen." ”

Seeing what Kudo Shinaku had in his hand, Hattori Heiji was also surprised, he didn't expect that what he found was actually a trap set by the murderer. If Kudo Shinichi hadn't found other fishing lines, he would have said that Kudo Shinichi was, but Kudo Shinichi actually had the same fishing line in his hand, and there were so many of them, it was impossible for him to refute it.

Kudo Shinichi's words were not finished, "The murderer's face and the place outside the room are designed, so no matter where the old gentleman was at the time of the crime, it must have something to do with the murder." ”

Hattori Heiji said: "But this study is a perfect secret room, do you want to tell me that the deceased committed suicide?" ”

Looking at Mrs. Tsujimura, Kudo Shinichi smiled while sweating, "No! He didn't commit suicide, he was murdered! And I've already found the clues left by the killer. ”

Kei Suzuki asked, "Oh, what's the clue?" How did I not find out? ”

Kudo Shinichi looked at Hattori Heiji and said, "Do you remember?" At the time the victim was killed, opera was playing in this room. And in front of the victim, there was a stack of books. ”

After saying this, Kudo Shinichi looked back at Mrs. Tsujimura and said, "Playing the opera is a preparation for the murderer to eliminate the possible screams of the victims. The book is a cover-up to prevent the victim from having a painful expression when he is stabbed. ”

Hearing Kudo Shinichi say this, the others didn't have anything yet, and Heiji Hattori laughed. "Haha, how is this possible? Why do you say that the murderer took such great lengths to cover it up? ”

Kudo Shinichi: "The murderer did it for you, Heiji Hattori." ”

Heiji Hattori was taken aback, thinking that Kudo Shinichi meant that the murderer was trying to kill him. However, Kudo Shinichi then said: "Of course, you are not the only one, Mr. Mori and Xiaolan, who entered the study with you at that time, if they noticed the movements of the deceased, they are likely to destroy the murderer's plan." ”

Kudo Shinichi's words are here, how could Hattori Heiji still not understand what Kudo Shinichi wants to say. "So I'm sure the murderer was the one closest to the deceased at the time. Mrs. Tsujimura, the murderer is you! ”

Hearing Kudo Shinichi say this, all the people in the Tsuji Village family couldn't believe Kudo Shinichi's words.

Kei Suzuki walked slowly a few steps to the place where the deceased had fallen and said, "So, when you came in, the deceased was still alive?" ”

Kudo Shinichi: "That's right, Madame should have just used some kind of medicine to put the deceased to sleep." The lady then stabbed the deceased with a poisonous needle while pretending to wake him up. In fact, it was normal for no one to notice at that time, because the medicine used by Mrs. was relatively strong, and the poison needle was highly poisonous. So after the victim was stabbed with a poisonous needle, he died quietly at that time. The reason why Mrs. Tsujimura prepared the opera and those books was just a precaution. ”

Suzuki Keidao: "Isn't Madame afraid that the after-mortem will find out the ingredients of sleeping pills after the autopsy?" ”

Hattori shook his head and said, "No one will know!" Because we had always thought that the deceased was dead before we entered the house. According to what we said earlier, the murderer used a poison needle to make the deceased fall asleep without resistance. That is to say, the murderer deliberately brought the detective in, and took advantage of their psychological blind spot that they felt that the murderer would not kill in front of them, and carried out a psychological secret room murder, and everyone would not be aware of this. ”

Then Hattori Heiji turned to Shinichi Kudo, who was covered in sweat: "That's what you mean, Kudo?" ”

Seeing Kudo Shin nodding, Hattori Heiji said in a deep voice: "Since you said so, then please come up with evidence!" Because at that time, Mrs. Tsujimura didn't take out the poison needle at all. ”

Although Hattori Heiji himself thinks the same way, but without evidence, it is useless to say it well, and if he hires a better lawyer, it is entirely possible that Mrs. Tsujimura will be acquitted in court.

Kudo Shinichi stretched out his hand like Kei Suzuki and said, "Officer Suzuki, can you lend me the key?" ”

Kudo Shinichi's words also gave Suzuki Keichi a hint, and after Suzuki Kei handed the key to Kudo Shinichi, he suddenly realized: "Do you mean that Mrs. Tsujimura hid the poison needle in the keychain?" ”

"That's right!" After Kei Suzuki took the key to the study in his hand, Shinichi Kudo pushed open the keychain and said, "When I entered the study, Mrs. Tsujimura had already taken out the poison needle in front of everyone, but everyone didn't notice it. Because the poison needle is hidden in the keychain! ”
