"Officer, we noticed something wrong with the keychain on the deceased!"

"What, really?"

Officer Twilight quickly approached, followed by Heiji Hattori.

Then you can see that when the oval keychain of the key is opened, there is a white tape attached to it, and there is a thin slit that is clearly protruding in the middle.

"It's ......"

Officer Twilight looked at Zuo Ye and found that the other party's gaze was also on the keychain, so there was no squeak, and it seemed that some clues were still missing.

Unlike Sano, after seeing the keychain, Hattori Heiji seemed to have figured out something, and hurriedly ran out of the room, causing Officer Twilight to be stunned and looked at Sano again.

"What's the situation, Brother Zuoye, that kid seems to have found out, is it really okay?"

Looking at Hattori Heiji's back, Sano had a calm look in his eyes, but he didn't answer Officer Twilight, who had a sense of urgency.

For this case, Zuo Ye actually has an answer in his heart, but at present, there is still a crucial thing missing.

Sano doesn't know what Hattori Heiji's "sudden realization" behavior is, maybe he stepped on the murderer's pit, but it may also be because the other party found out the truth.

In any case, Sano is not suitable now, and there is no reason to speak out, so let's wait and see for a while, and wait until Hattori Heiji takes out his results and determines that the other party is wrong.

But at this moment, Conan, who had been shaking, suddenly fell to the ground with a thud, and Mao Lilan hurriedly rushed over, temporarily leaving the room with this essence in his arms, and called the doctor.

What's the situation, how did Conan fall, then this case, is it really only on his own.

Seeing that he was missing an important clue trigger, Zuo Ye's brows couldn't help but furrow slightly.

And because of Conan's fainting, there was also a brief chaos in the study.

Only a minute after Conan left, Hattori Heiji had already returned to his study, his face full of confidence.

"I've seen through the truth about this secret room murder!"

"Really?"

Officer Twilight was shocked, although he was very upset to be the first to see the truth by a high school detective from out of town, but as a police officer, of course, he couldn't choose not to admit the truth because of his personal feelings, and immediately asked Hattori to show it.

Then, Officer Twilight temporarily plays the role of the deceased, as he resembles the size of Isao Tsujimura.

"The murderer's murder method is actually very simple, although this study is indeed a secret room, but there is also the only flaw, that is, the gap under the door of the study."

"The murderer first kills the deceased, then takes that pose, and then puts a piece of tape and fishing line on the inside of the key, and after locking the door with this key, he pulls the fishing line through the crack of the door, and then he can re-enter the door, go all the way to the pocket of the deceased, and finally pull the line out with a strong pull."

"Really, really got in!?"

Hattori Heiji pushed the door open again, looking at the group of people who were shocked because the key really went into Officer Twilight's pocket, the corners of his mouth rose slightly: "And the identity of the murderer is none other than Mr. Toshimitsu, because the fishing line I found was turned out of the trash can in the Japanese-style room where Mr. Toshimitsu stayed before!"

Toshimitsu Tsujimura looked blankly at the fishing line in Hattori's hand, and then smiled bitterly: "That's right, it was me who killed Ah Xun."

actually admitted it.

Sano frowned, and walked quickly to Tsujimura Gonge, who was standing in the corner, so that Officer Twilight, who had just wanted to settle the result, swallowed his voice back.

"Brother Zuoye......?"

Under Officer Twilight's reaction, the eyes of everyone present were subconsciously focused on Zuo Ye's body, watching him reach out and pat Tsujimura Koe's shoulder.

Before Koie Tsujimura, who was stunned by the situation in front of him, had no time to react, he only felt as if someone had chiseled his shoulder with a sledgehammer, and suddenly exclaimed, almost sitting on the ground without a butt.

"This is!?"

When the policemen, including Officer Twilight, saw this scene, they all shouted in disbelief, especially Officer Twilight, who trembled even more: "Brother Zuoye, what's the situation, the murderer is Mrs. Tsujimura?"

"What?"

Hattori Heiji stared at him in confusion: "What are you talking about, officer, haven't all the murderers already confessed?"

"This ......"

Officer Twilight also hesitated, and muttered, "But the hand of judgment has worked against Mrs. Tsujimura......

"Hand of Judgment???

Hattori Heiji was confused again: "What is this?"

"Ah, this is a way for Brother Zuo Ye to break the eucalyptus, just like Brother Maori will fall asleep every time he breaks the eucalyptus, every time Brother Zuo Ye breaks the eucalyptus, he will pat the suspect on the shoulder first, and anyone who reacts abnormally after being slapped on the shoulder by Brother Zuo Ye will basically sit on the identity of the murderer, and everyone will privately give Brother Zuo Ye this magical way to determine the murderer, and give the name of the hand of judgment."

Officer Twilight quickly explained to Heiji Hattori, but the other party's expression became more and more strange.

「…… Are your detectives in Tokyo so metaphysical in their way of breaking the eucalyptus??"

"I don't know ...... that."

Officer Twilight took a few seconds to end the exchange with Hattori Heiji, and hurriedly approached Zuono's side: "Brother Zuono, tell me about the situation!"

"There's nothing to say, it's not the old man who killed the killer, it's the Tsujimura ...... Madame."

Zuo Ye lit a cigarette: "As for the murder method, it is not as complicated as Hattori Heiji thought, but very simple and rude, killing people in person."

"What, kill someone in person!?"

Before Officer Twilight could speak, Heiji Hattori shouted, "Do you mean that Mrs. Tsujimura was the one who killed us in front of us after entering the room?"

"Hmm."

Sano nodded in confirmation.

Although Hattori Heiji was very reluctant to admit Sano's statement, he was keenly aware of the possibility: "If this is the case, some things do make sense, including the fact that the deceased clearly liked classical music, but there was an opera playing in the room, and there were books on the desk that blocked the view."

"It's just that there are still some things that don't make sense, for example, Mrs. Tsujimura's actions can't be too hidden, besides, my method just now didn't fail, so the possibility that the murderer is Old Man Toshimitsu is not impossible, not to mention that he himself has already admitted it."

In the end, Heiji Hattori regained confidence in his reasoning: "So in comparison, my reasoning is obviously more correct!"

Zuo Ye didn't pay attention to Hattori Heiji, just looked at Tsujimura Gonge, whose pale face gradually recovered after Hattori Heiji spoke: "Sachiko Katsuragi, it's your daughter."

"What!?"

Sachiko Katsuragi, who had always been just a bystander, was stunned, and the blood-colored face of Tsujimura Gongjiang was even more pale in an instant.

"Tsujimura Xun is a famous diplomat, but he has some notoriety, I heard that his wife, who is your ex-husband, was also a diplomat, but was forced to abdicate or even commit suicide for some reasons, and these reasons should be your motive for killing."

Sano thought back to what he had just taken the time to read, and the extended information about Tsujimura Xun sent by Ginjiu, and analyzed the context of the eucalyptus.

In fact, as early as the beginning, Zuo Ye felt that it was wrong, because Tsujimura Gonge's mocking aura was a little unreasonable, and what I saw on the bookshelf was a photo of Tsujimura Gongjiang when he was young, which was too similar to Sachiko Katsuragi.

Zuo Ye also had a guess in his heart, so he began to rummage through the information on his mobile phone, and confirmed that Tsujimura Gongjiang had a daughter earlier, and also determined the truth of the matter.

"You learned the truth about what happened back then, and you saw that your daughter was about to marry the enemy's son, so you had the idea of killing, right?"

Tsujimura Gonge's eyes widened, and he sat down on the ground, his face full of ashes, and finally nodded: "That's right, that's it, back then

We didn't know anything, but under his rhetoric, I gave Sachiko to my relatives to raise and marry him."

"It wasn't until later that Guishan brought back a girl, I thought it was just an accident and looked alike, but I didn't expect his face to change greatly after seeing Sachiko's photo, saying how his son could marry that man's daughter, and I learned the truth."

"That guy doesn't deserve to be a diplomat at all, just because my husband doesn't want to be in the same league with them, he framed me, pulled my husband down, and forced him to commit suicide......

"Mom......

Sachiko Katsuragi's tears had already flowed uncontrollably, and if it weren't for Takazen Tsujimura on the side, I'm afraid she would have fallen to the ground.

"But how did she manage to kill people with a poison needle without us noticing, and where did she hide it?"

Hattori Heiji was still puzzled: "Also, since this matter has nothing to do with Mr. Toshimitsu, why did he replace Tsuji...... Mrs. Gongjiang is guilty?"

"I guess I hid the needle in the keychain."

Sano glanced at Toshimitsu Tsujimura: "As for him, it's probably guilt."

Toshimitsu Tsujimura smiled bitterly again: "Yes, because of the events of the past, in fact, I was also involved, but my mind was not clear at that time, and now I really want to atone for a little sin......

"Anyway, the truth is finally revealed."

Officer Twilight clapped his hands, "The motive, the modus, the evidence, are all here, and this case is over."

"Evidence?"

Zuo Ye raised his eyebrows: "Where is the evidence?"

"What do you say?"

Hattori Heiji frowned and said, "Didn't you say that Mrs. Gongjiang hid the poison needle in the keychain, there must be traces in it, isn't that evidence?"

"This ...... Can it be used as evidence?"

Zuo Ye flicked the cigarette ash suspiciously: "Isn't that kind of thing just an excuse to get over, like she's happy or something."

「……」

Officer Twilight and Heiji Hattori showed dead fish eyes at the same time: "What are you talking about, it's not like you can just make excuses to get over, but then again, didn't you know that you already had evidence when you reasoned just now?"

Zuo Ye scratched his head: "I don't know, I thought there was no evidence, so I had to let her confess by herself."

Hearing this, Hattori Heiji couldn't help pursing his lips, and suddenly felt a little dry in his throat: "In fact, you have already figured out the reasoning just now, but you were forced to have no evidence, so you didn't say it, and then I accidentally stepped into the murderer's pit, so you had to ...... Choosing to speak directly?"

"Sort of, but it's not all because of this, after all, in my opinion just now, the evidence is already impossible, and the only way to let her confess is to make her confess."

Zuo Ye shrugged.

"In that case, why didn't you start reasoning earlier, Brother Zuoye?"

Officer Twilight couldn't help but ask, and Heiji Hattori, who was already feeling dry in his throat on the side, already chuckled in his heart after hearing this, and sensed that something was wrong.

"If the truth had been told earlier, wouldn't this Hattori detective in Kansai have a chance to tell even a wrong reasoning?"
