Saturday, February 1st, afternoon, the study of the Tsujimura family.

After listening to Kudo Shinichi's words, Heiji Hattori asked, "What did you say?"

"This is," the Twilight Police Department said in surprise, looking at their pockets, "pinholes!"

"What!" Hattori Heiji was taken aback.

"That's it," Kudo Shinichi said with a smile, "Let's not talk about whether this technique can be successful, if there has been such a technique, then Mr. Tsujimura must have a pinhole in his pocket." ”

"He must have used a fine needle. Heiji Hattori said.

"A thin needle may not leave a mark, but a long thread passing through it will not leave a mark without enlarging the eye of the needle. Kudo Shinichi said, "And Mr. Tsujimura's pocket is fine, so this incident never happened at all." In addition, Mr. Tsujimura's hips are much larger than those of the Twilight Police Department, and the pockets of his pants fold more when you sit there, and the tape on your hand alone cannot bind the fishing line, and the fishing line will fall off when the key enters the pocket. ”

"This ......," Hattori Heiji was speechless for a moment, and then asked, "Wait a minute, you just got here, how do you know about Mr. Tsujimura's hips and his pants pockets?"

"It's Conan, he's the one who called me. Kudo Shinichi smiled and said, "I said that there was a strange person in the office, and I came across a murder in a closed room, so I hurried here." ”

"Conan?" Hattori asked rhetorically, "You mean my observation is not as good as a child's?"

"This ......," Kudo Shinichi thought, a question that is really difficult to answer.

"Shinichi, where is Conan?" said Ran, "I can't find him anywhere. ”

"Well, you might have gone awry. Kudo Shinichi said, "Don't worry, I listen to his voice, and it seems that there is no problem." At the same time, I thought to myself, how can I explain the question of where Conan is going after a while?

The Twilight Police Department asked, "So who is the real prisoner?" This study is a completely secret room, is it possible that you want to say that Mr. Tsujimura wants to commit suicide?"

"Of course not, didn't he order the housekeeper Koike to inquire about the change in the political situation, how could he want to commit suicide?" Kudo Shinichi said with a smile, "The culprit of this incident is the person who put the fishing line in the Japanese-style room, that is, the person who asked the old Mr. Tsujimura to go to the Japanese-style room and wanted to blame the old Mr. Tsujimura." ”

"You mean Mrs. Tsujimura Koe?" asked Maori, surprised, "how is that possible?

"Is it really you?" asked Mr. Tsujimura.

"......" Tsujimura Koe did not speak.

"Mrs. Gongjiang took advantage of people's psychology, which is why she arranged this study like this. Kudo Shinichi said with a smile, "When you came in, the opera was playing in this study, and there was a stack of books on the desk. ”

"What's wrong with that? Although most of the records in this stereo are classical, there are also operas, so it's not surprising to listen to them once in a while. And these books are all about the UK, so I guess they're refreshing. ”

"One may be fine, but the combination of the two is problematic. Kudo Shinichi laughed, "The opera will be played loudly to cover up the 'ah' sound that Mr. Tsujimura might make when he is stabbed." These books block the view of Mr. Tsujimura from the angle of the doorway, and are intended to hide the painful expression that Mr. Tsujimura may have when he is stabbed. Mrs. Koe asks Mr. Tsujimura to drink the medicine, sets up the scene, and then goes to the Maori Detective Agency. By the way, the cups were disposed of on the way, which could explain why the cups with medicine were not found at home. Then she brought Uncle Tsuji and others to make an alibi for her, and asked Mr. Tsuji Village at the top of the stairs to go to the room to blame him, she must have made an appointment with Mr. Tsujimura in advance, and Mr. Tsujimura has been waiting for her, so there is no alibi, so he will come to her when he sees her back, and as long as the police find the hidden needle and fishing line in the Japanese room, and the famous detective Mori Kogoro is there, he must be able to think of the method you said just now, so that Mr. Tsujimura has no choice. I think that's why Mrs. Gongjiang went to Uncle Maori. ”

"Maori?" the Twilight Police Department was skeptical.

"Ahem!" said Mori Masashiki, "it's still very easy to thread a needle. ”

"Mr. Kudo, it's true that as you said, I made an appointment with my son and Koe. Mr. Tsujimura said, "I rarely caught a big red kaji, which is real sea bream. You know, of course, this kind of thing has someone to share to have a sense of satisfaction and achievement. ”

"By the way, Kudo," the Twilight Police Department asked, "Wouldn't that sleeping pill raise suspicion if it was detected?"

"Normally, you would think that the incident happened before you came in, right?" Kudo Shinichi said with a smile, "I would think that Mr. Tsujimura was made to drink medicine to reduce trouble." ”

"Kudo, you said that Mrs. Tsujimura Gonge deliberately brought us people here, and used the blind spot that no one would kill in front of everyone to carry out psychological secret room killings, do you mean that? Even if the structure of the keychain in Mrs. Gongjiang's hand is the same as that of Mr. Tsujimura's, it is only possible to hide a needle. When she entered the room, she could naturally separate the keychain in her hand without everyone noticing, push out the hidden poisonous needle, and stab Mr. Tsujimura, but the scar on the back of Mr. Tsujimura's hand was not the same as the scar of the needle. There was also the problem of bleeding, and when we saw it, the wound had stopped bleeding on its own. Fujibe Heiji asked, "I don't know if the kid named Conan told you about these two points, can you explain it?"

"Quite simply, the wound was not made by a needle, but by a needle. Kudo Shinichi smiled, "As for the bleeding, there is no bleeding at all." ”

"No bleeding? Heiji Hattori said, "That wound...... Uh......"

"You also thought about it, because the toxicity is so great, so there is no bleeding at all. Kudo Shinichi smiled, "That's why Yamazaki is sure that it is highly poisonous." ”

"I see. The Twilight Police Department said with Maori.

"Huh?" the Twilight Police Department looked at Maori angrily.

"Heh, heh. Maori laughed dryly in reply.

Kudo Shinichi said, "Mrs. Gongjiang, please take out your key. Then he took the keychain from Mrs. Gongjiang's hand and parted it, revealing a thin slit.

"Ha, where's the poison needle?" Hattori Heiji said with a smile, "This room has been searched, and Mrs. Gongjiang has been here since the haircut, and she has no way to deal with that poison needle." ”

With the empty keychain, Kudo Shinai smiled and said, "It's the same as I thought." Then he said, "Dusk Police Department, please have someone test it, as long as you know if there is poison, it doesn't matter what poison it is." Also, there is no need to look for poison needles. ”

"Why?" asked the Dusk Police Department, confused.

Kudo Shinichi didn't answer, but asked Takazen Tsujimura, who came in, "Mr. Takazen Tsujimura, can you please go out for a while?"

"Huh?" Takatozen Tsujimura wondered.

Mr. Tsujimura said, "Let's get out." ”

Takazen Tsujimura said, "Yes, grandpa. Then he said to Ran, "Miss Maori, the doctor and I have never been able to find the child named Conan. ”

"No need to look for it. Kudo Shinichi said, "Thank you." ”

"You're welcome. After saying that, Takazen Tsujimura went out.

Kudo Shinichi walked to the front of the bookcase, took a photo from the top layer, and put the familiar small box into his sleeve, and said with a smile in his heart, it is convenient to get taller. Then he said: "I think Mrs. Gongjiang will do this, because of this." Then he asked, "Old Mr. Tsujimura, you already know, right?"

"This is ......" Lan covered her mouth in surprise.

"Isn't this Miss Sachiko?" asked Maori, "who is the man next to her?"

"This should be a photo of Mr. Tsujimura and Mrs. Tsujimura when they were young. Hattori Heiji said, "It turns out that Mrs. Gonge's motive for investigating Miss Sachiko is this, and she wants to know if it is her own daughter." ”

"No, Mrs. Gongjiang already knows, so she opposes Miss Sachiko marrying in. Because it has a bad reputation. Kudo Shinichi said, "As for the motive for the killing, Mr. Tsujimura, I think you could explain it to us, right? I remember you just said the phrase 'it's really you.'" ”

"Alas," said Mr. Tsujimura, "in order to get Koe, Aki sent Kimoe's husband, Mr. Kenji Yamashiro, who was the same as Aki, to prison by despicable but not illegal means, so that Mr. Yamashiro thought that Mr. Yamashiro was a bad person and broke up with him, and later Mr. Yamashiro died in prison. ”

"Don't blame it all on your son, I don't think you can get out of it," Hattori Heiji said, "That's why Lady Gongjiang wants to blame you." Then he asked Mrs. Gongjiang, who was in tears and biting her lower lip, "Is that so?" and then saw that Mrs. Gongjiang did not answer and asked, "Why don't you speak?"

"No need to ask, she won't say anything. Kudo Shinichi said, "Mrs. Gonge and Miss Sachiko are mother and daughter, please don't tell everyone." It's better to let them solve this kind of household chore by themselves. ”

"No problem. "The relationship between Mrs. Gongjiang and Miss Sachiko has nothing to do with this incident, so I can help them keep it secret." Then Mrs. Gongjiang saluted herself and the others, and asked Kudo Shinichi, "How do you know she won't say anything?"

"Wait a minute, it's okay to say the rest, including the fact that you know that Mrs. Gonge is against Miss Sachiko and Mr. Kizen," Hattori Heiji asked, "But, Kudo, how do you know what Miss Sachiko looks like?"

"yes, Shinichi. Lan asked, "Are you hiding near my house, spying on me?" At this, Lan's face flushed, "That's why you never ask me about it." Then he said angrily, "You must be around here, watching me worry about you and secretly laughing at me." ”

"I'm a detective, how are you doing, you can deduce it by listening to the voice. Kudo Shinichi smiled and said, "As for some of your things, you know, Conan lives with you, and I know what time you brush your teeth every day, so why bother asking." ”

"I see. Lan said embarrassedly, and at the same time thought to himself, Conan, didn't say anything that shouldn't be said, did he?

"Hey," Hattori said, "you haven't answered my question yet?"

"Did you hear what I said earlier? I didn't say that Mrs. Koe and Miss Sachiko looked alike, I didn't know what Miss Sachiko looked like, but someone told me there was something wrong with this picture. Kudo Shinichi smiled and said, "As for the question of Mrs. Gongjiang not speaking, it will have to wait until the results come out, because someone has said to Mrs. Gongjiang that if you don't want to go to jail immediately, you won't say anything for the time being." ”

"Anyone?" asked Hattori Heiji, "who?"

Ran asked, "You mean Yamazaki?"

"Yes, the poison needle should have been taken by him and taken to the hospital for testing. Kudo Shinichi said with a smile. And that stroke, it may be that Yamazaki saw that Mrs. Gongjiang pushed out a poisonous needle to stab Mr. Tsujimura's vital point, such as the neck, and when he wanted to seize it, an accident occurred, so that the tip of the poisonous needle crossed the back of Mr. Tsujimura's hand. ”

"Are you kidding? If that Yamazaki knows about these things, what else do you want us to do? Just say it?" Hattori Heiji asked rhetorically, "And what kind of poison is it, just ask Mrs. Gongjiang directly, why bother to test it?"

"The test is necessary, and no one knows what will happen when the poison is applied to the needle. Kudo Shinichi smiled and said, "As for the previous question, I really don't have a good evaluation. I can only tell you that if Tsujimura had lived first, Yamazaki would have persuaded Mr. Tsujimura to take the matter by himself, so Mrs. Gongjiang would not speak. ”

"Is that okay?" asked Hattori in surprise.

"Why not?" said Kudo Shinichi with a smile, "but I don't know what he's going to do." ”

"Alright," the Dusk Police Department said angrily, "Looks like this is the end of the matter." Then he said to Maori, "You come with me, too." ”……
