Conan wants to lie down but won't let him

"So what about the fishing line evidence I found? If it wasn't this method, how could I find the corresponding evidence?"

Hattori Heiji still refuses to accept the defeat and is already at the stage of being stubborn even when a dead duck is about to die. As the saying goes, one won't give up until one reaches the Yellow River, and one won't cry until one is in the coffin!

Since you, Hattori Heiji, have asked the question sincerely, then Kudo Shinichi will definitely give you a hammer to hammer!

"That was just a trap set by the murderer to frame Mr. Tsujimura Toshimitsu. He deliberately wanted the detective to figure out this trick so that he could frame him. It was a two-birds-with-one-stone tactic!"

The murderer was negligent in folding the key and putting it in the layer of the victim's double pocket. If he had put it in the single pocket, I might have fallen into the trap.

However, after all, it was a method imagined by the murderer herself, and she had not practiced it herself, so although it was feasible in theory, it was difficult to implement in practice.

The fishing line you found in the Japanese-style room is not really evidence at all, because there are trash cans for such fishing line in every room of the house.

In other words, the murderer couldn't tell which room Toshimitsu Tsujimura would appear in, so she placed fishing lines in every room to frame him, waiting for the detective to find them!

While Kudo Shinichi was reasoning and analyzing, he handed the fishing line he had just found from another room to Hattori Heiji.

"So, now you understand! This old man was one of the murderer's targets from the beginning. He wasn't just finding someone to be a scapegoat in order to exonerate himself.

The placement of so many fishing lines clearly indicates a clear purpose and direction. Furthermore, the elderly man's willingness to cooperate and confess to his guilt upon being accused of the crime is evident.

It seems that Mr. Tsujimura Toshimitsu had done something bad to the murderer before, and he has always felt guilty about it, so he lied and confessed.

"But this way, the room becomes a completely sealed chamber again. Could it be that you want to say that the deceased committed suicide?"

Hattori Heiji always felt that something was not right. After going around in circles like this, the room turned back into a secret room again.

"No! He didn't commit suicide! And the murderer also left clues to the real method she used." Kudo Shinichi said directly and firmly.

"The real method?" Hattori Heiji repeated and asked back.

"Have you forgotten? When the victim was found, opera music was playing in this study. And there was a pile of books piled high in front of the victim.

The murderer played the opera to prevent the victim from screaming when the poison needle was injected. And the pile of books was also a cover-up to prevent the victim from showing any expression of pain and struggle after being stabbed!

Kudo Shinichi reveals the murderer's true method, which is actually a psychological chamber technique.

On the surface, it looked like a closed-room murder case, but in fact, it was not a closed-room murder case at all. The murderer used a key to open the door and came in, and committed the crime in front of everyone, in full view of the public!

"How is this possible? Who was the murderer trying to cover up for by going to such great lengths?" Hattori Heiji got the direction wrong and couldn't figure it out.

"Of course the murderer did this to hide it from you, Hattori Heiji!" Kudo Shinichi pointed out directly that it was done to avoid being discovered by you, Hattori Heiji.

"What did you say!?" Hattori Heiji was completely confused.

"Of course you're not the only one! Uncle Mori, who entered the study with you, as well as Fujiwara Hiroshi, Xiaolan and others are all the people the murderer wants to hide! Because if they are discovered, it will ruin the murderer's plan!"

Kudo Shinichi said.

"So, could it be..." Hattori Heiji opened his mouth wide.

"So I am sure that the murderer is the person who was closest to the victim after entering the study!" Kudo Shinichi turned around handsomely and pointed his finger at Tsujimura Kimie!

"That's right! The murderer is you, Mrs. Tsujimura!"

(The Great Wilderness Prisoner Finger has been activated. Whoever it points at will go in and start the sewing machine!)

"Ah? Madam killed the master? How is this possible?" The butler was the first to exclaim three questions in a row.

Tsujimura Kimie remained silent.

"So this isn't a closed-room murder at all. Mrs. Tsujimura opened the door and entered the study in broad daylight in front of everyone, and killed the victim in full view of everyone while they weren't paying attention!

The evidence is the exact same key in the hands of Mrs. Tsujimura Kimie. I think when the key ring is opened, there should be a recessed hole for the poison needle inside. This is the decisive evidence!"

Kudo Shinichi directly stated his reasoning. The truth is simple. The real truth does not have those fancy methods of Hattori Heiji's reasoning. It is just the simplest way to open the door and enter.

When Hattori Heiji heard the truth, he couldn't help but take two steps back. He had committed a big taboo. He wanted to win too much and prove himself too much.

As a result, a simple matter was complicated, a method was forced, and in the end it was overturned in the face. All other possibilities were ruled out. No one expected that the truth was that he used the key to open the door and break the secret room. This was really hard for Hattori Heiji to accept!

"As for why the lady killed her husband, I think the answer should be in this photo." Kudo Shinichi picked up the photo on the desk and handed it over.

Hattori Heiji couldn't wait to go forward to check the reason. Inspector Megure and Mouri Kogoro followed closely behind him, came forward and carefully observed the contents of the photo.

Fujiwara Hiroshi was very calm. He knew that the development of the case was exactly as he expected, and the relationship between Takayoshi Tsujimura and Sachiko Katsuragi would soon break down.

Then it is Fujiwara Hiroshi's turn to conquer Katsuragi Sachiko. He made a mistake with Miyano Akemi last time, so this time he must get back at Katsuragi Sachiko!

"This photo is just an old photo! There's no difference with this one?" Inspector Megure looked at the photo and didn't notice anything for a moment, so he muttered to himself.

"Ah... this is..." Hattori Heiji had not noticed this photo before, and as a result, such an important clue was ignored by him!

"This is a photo of the lady when she was young. She looks exactly like Miss Sachiko, except for the hair color!" Maori Kogoro looked in the direction of Hattori Heiji's finger, and was also surprised to find this situation!

"What did you say!?" Hearing Kogoro Mouri say this, Inspector Megure quickly looked over.

He had clearly seen this photo before, but why hadn't he noticed it? Was there really such a huge difference between a Metropolitan Police Department inspector and these detectives?

"Ah!?" Katsuragi Sachiko and Takayoshi Tsujimura, who were far away, also heard this and couldn't help but open their mouths wide!

"Could it be that Mr. Guishan is looking for a partner based on the standards of his stepmother, Madam Gongjiang? Then why does Madam Gongjiang hate Miss Sachiko so much?

Could it be that because they look so much like each other, Mrs. Gongjiang instinctively rejects Miss Sachiko? "Mouri Kogoro was commissioned to investigate Miss Sachiko, and he was very puzzled by this situation!

"Humph! Of course we look alike! Because I am Sachiko's biological mother!" Tsujimura Kimie stopped pretending and directly said that she was Sachiko's mother.

"What did you say!?" everyone said in unison at this time.

Only Sachiko stared with her eyes wide open and her mouth hanging open for a long time. This news was too shocking for her.

Who could have imagined that the stepmother-in-law who disliked him in every way just a few minutes ago would become his biological mother in the blink of an eye.

Wouldn't that mean she and Guishan would become brother and sister? Sachiko felt like her eyes were going to go dark. Suddenly, such a devastating thing happened to her. Not everyone could stand it.

"So, Sachiko is the daughter of you and the diplomat?" Inspector Megure asked with his eyes wide open.

"No! To be honest, Sachiko is the child of me and my ex-husband!" Tsujimura Kimie paused briefly here, and then said with a ferocious look on his face.

"Yes! She is the daughter of diplomat Kenji Yamashiro, who was forced to leave society 20 years ago by my husband, Tsujimura Isao, on charges of malfeasance."

"Kenji Yamashiro!?" Inspector Megure took a step back, and his whole state looked like he was frightened and trembling.

"Yes, that's the diplomat who died in prison 15 years ago. Tsujimura's real goal was to bring down Yamashiro, who was also a diplomat at the time but was in a hostile relationship with him.

Then he could have me, who was Yamashiro's wife at the time! But I was completely unaware of this. After Yamashiro was arrested and imprisoned, I entrusted Sachiko to Yamashiro's relatives for upbringing!

At that time, Tsujimura Isao coaxed me with sweet words and told me that he divorced his ex-wife because of me.

And so I easily fell into Tsujimura's trap and started living with this devilish man."

Tsujimura Kimie paused briefly here and then continued.

"I discovered the truth of the whole thing when Takayama showed his girlfriend's photo to his father and then told Tsujimura Isao that he would bring Sachiko back to meet them.

At first, I just thought we happened to look alike. I didn't expect Tsujimura Isao to object so unexpectedly, and his facial expression became distorted.

He looked extremely angry, and then he scolded Takayoshi Tsujimura harshly, telling him that he must never be with this woman.

I also decided not to let that man's daughter marry my son and let them get together.

Under my suspicion, I couldn't help but ask Tsujimura. Then Tsujimura was like a possessed person at this time, telling me how he framed Yamashiro for dereliction of duty.

After listening to his confession, I realized that my father-in-law had helped him in this matter.

So I designed this murder plan, which was to kill Tsujimura Isao with my own hands and kill my enemy, and also to shift the blame to my father-in-law.

So I went to the Mouri Detective Agency in person, ready to ask Kogoro Mouri to act as a witness, and then guide everyone to form a psychological secret room.

Once you have formed the illusion of a psychological chamber, and slowly investigate, this erroneous thinking will continue to interfere with you, and then you will no longer be able to guess that I am the murderer. "

"I'm sorry, Kimie! I don't know what happened to me at that time." Tsujimura Toshimitsu sincerely apologized to Tsujimura Kimie.

"I see! You regretted the mistakes you made back then, so you voluntarily walked into the trap set by Madam Gong Jiang!

So that's why you just admitted that you did it, right?" Inspector Megure opened his eyes wide at this moment, as if he had sorted out everything, and began to conclude his reasoning.

"That's right! When I realized that Gong Jiang wanted me to take on the identity of the murderer, I knew why she killed Ah Xun, and she knew all the wrong things I did back then."

Toshimitsu Tsujimura also answered Inspector Megure's questions.

"At this point, pretending to be a good person is useless. Dad, Shancheng was falsely accused of a crime because of you and died in prison for no apparent reason."

Police Officer A, who was a passerby, saw that Tsujimura Kimie had almost finished speaking, so he came forward, handcuffed her, and prepared to escort her away.

Officer Takagi has been performing well recently, and his promotion has been quite rapid. Originally, this kind of miscellaneous work was done by Officer Takagi, but now this part of the work has been separated from Takagi.

"Sachiko, please forgive me for not fulfilling my responsibilities as a mother. I also hope you won't hold a grudge against me. I was rude to you and looked down on you because I didn't want you to marry Guishan.

After Tsujimura Isao told me the truth about what happened back then, and when I learned that you were my biological daughter, we both agreed on the relationship between you and Guishan.

I hope you can think carefully about the real choice. Your father was killed by Guishan's father, and Guishan's father died at my hands.

You are the children of the enemy who killed each other's fathers, and I am Guishan's stepmother, so you are also a kind of mutant siblings, and you have a relationship background of enemies!

If you listen to my mother's advice, don't get married. There will be endless troubles! That's all I have to say. You should make your own decision!

When Kimie Tsujimura was escorted to the door, he turned his back to Sachiko and spoke these heartfelt words.

For Sachiko, the information was too overwhelming in just a few minutes. Not only Sachiko, but Takayoshi Tsujimura was also stunned. However, he also had a premonition that his relationship with Sachiko was over.

He himself didn't know how to face Sachiko, and he also believed that Sachiko probably didn't know how to face him! Looking at Sachiko standing there, Takayoshi Tsujimura didn't say much. He left the study alone and went out to digest this large amount of information.

Sachiko also calmed down and thought carefully, and she finally understood that her relationship with Guishan was really over. Guishan left without saying a word, which made his attitude very clear.

Sachiko Tamaki looked at the surroundings and thought, it seems this is not her home after all. She came here originally for Guishan, and now it is time to leave this place of sad memories.
