Heiji Hattori was taken aback by Kudo Shinichi's reasoning and said, "The poison needle is hidden inside the keychain?" ”

Pushing the keychain on the deceased's body open, so that Kei Suzuki and the others could see the adhesive tape inside the keychain, Kudo Shinichi: "I think Mrs. Tsujimura's keychain should be the same as this one on the deceased, right?" So the keychain in Madame's hand should be able to be opened, can you take out your key and show it to everyone, Madame? ”

Kei Suzuki had been paying attention to Mrs. Tsujimura, and just when Shinichi Kudo said that the opera and the book were all used to cover up, Kei Suzuki noticed that Mrs. Tsujimura's face was already pale, and her hands were clasped together, nervous. It's just that Mrs. Tsujimura has no other intentions, and Kei Suzuki doesn't make excessive moves.

When he heard this, Kei Suzuki finally walked to Mrs. Tsujimura and said, "Madam, can you show me your keychain?" ”

Mrs. Tsujimura's face was pale, and cold sweat slowly oozed from her forehead, but she didn't move. Kei Suzuki didn't wait for Mrs. Tsujimura to respond, and took out the key to the study from Mrs. Tsujimura's kun bag.

Kei Suzuki opened the keychain, only to find that there was a slender groove inside the keychain. Judging from the shape and size, it seems to be able to put down the poison needle found at the scene of the murder.

Kudo Shinichi and Hattori Heiji also saw the groove in the keychain, and Kudo Shinichi: "According to my speculation, this groove is only the groove of the poison needle." When Madame entered the study, she took the poison needle out of the groove while pretending to put the key. Therefore, this grooved keychain is the most powerful and direct evidence to prove that Mrs. is the murderer. ”

Kei Suzuki looked at Mrs. Tsujimura and said, "Madam, why did you kill Mr. Tsujimura?" Is it related to Miss Sachiko? I found out that when you were younger, you were quite similar to Miss Sachiko's Zhang. ”

Hearing Kei Suzuki say this, Sachiko Katsuragi exclaimed, and Takazen Tsujimura even shouted: "How is it possible! ”

said so, but when the two of them saw the photo on the bookcase, they had to admit this fact. Xiaolan also said after seeing the photo: "Really, except for the color of the hair, it is almost exactly the same!" ”

Mrs. Tsujimura was also annoyed that some secrets had been revealed at this time, and finally spoke, only to hear her say coldly: "Of course she is like me!" Because she's my daughter! ”

"What?" Kei Suzuki found out very early, which is not very strange, but Takazen Tsujimura and Sachiko Katsuragi are two sentient beings. People are very panicked, if Sachiko is also the daughter of Mrs. Tsujimura, then doesn't it mean that Sachiko Katsuragi and Takazen Tsujimura are brother and sister?

You must know that the two of them have been together for a long time, and they have done everything they need to do, and now they are suddenly told that they are actually brother and sister, and they can't accept it at all!

But fortunately, Mrs. Tsujimura quickly interrupted everyone's reverie and said, "Sachiko is the child born to me and my ex-husband. ”

When she said this, Mrs. Tsujimura's voice suddenly became resentful, and she said sharply: "It is the biological daughter of the diplomat Kenji Yamashiro who was forcibly accused of dereliction of duty by a devil-like man like Tsujimura twenty years ago, and was erased from society. ”

Kei Suzuki looked at Mrs. Tsujimura suspiciously and said, "Kenji Yamashiro? ”

Mrs. Tsujimura's face was full of pain and said, "That's right, it's the diplomat who died in prison fifteen years ago. The reason why Tsujimura slandered Kenji Yamashiro was that his purpose was to remove his rival Yamashiro from power, and at the same time, he also wanted to get my hands on me, who was still Yamashiro's wife at the time. ”

"But I didn't know it at all, and after I was arrested in Yamashiro, I almost broke down. Sachiko was picked up by relatives because of this, and the man in Tsuji Village said at this time that he divorced his wife for me, so I easily fell in love with Tsuji Village and began to live with this man like the devil. ”

When she said this, Mrs. Tsujimura's voice also fell. Obviously, he blames himself for not discovering this fact in the past 20 years. "I really knew about these things when Takazen brought Sachiko's picture home."

"At first, I thought Sachiko was just a coincidence. Unexpectedly, Tsujimura yelled as if out of control, saying that I must not let Guishan be with this woman, and I must not let that man's daughter be with my son. ”

Seeing Tsujimura's reaction so violently, I couldn't help but ask him why. I don't know if it's because he has been holding this matter in his heart for twenty years, which makes him very proud. Upon my inquiry, he began to gush on and on about all the dereliction of duty he had framed Yamashiro. That's when I learned that my father-in-law also helped him do this. ”

The old man Toshimitsu Tsujimura has always been very calm, and he didn't show much surprise even when he found out that his son was dead, and when he heard Mrs. Tsujimura's words, he said with remorse: "I'm sorry, Gonge! I don't know what happened to me at that time. ”

Mrs. Tsujimura did not accept the old man's apology at all: "It's useless for you to pretend to be a good person now, Dad." Yamashiro has died in prison because he has been charged with trumped-up charges by you. ”

Now that she has confessed to the murder and explained the reasons clearly, Kei Suzuki is no longer polite and motions for the other police officers to take Mrs. Tsujimura away. When Mrs. Tsujimura, whose hands were cuffed, walked to the door of the study, she finally stopped, and she still cared about Sachiko, a daughter she hadn't seen for 20 years.

"Guishan!"

Although he knew that she was the one who killed her father, but Guizen didn't know whether to hate her or not, and when he heard his mother suddenly call himself, Takazen Tsujimura reflexively responded.

Mrs. Tsujimura didn't look back, she was afraid to see the look on her daughter's face. "Although I am not qualified to ask you for anything now, Sachiko will ask you!"

Speaking of which, Mrs. Tsujimura finally couldn't hold back her tears.

When Tsujimura Takazen heard this request, he was stunned, but he didn't hesitate at all, and immediately nodded: "Okay!" ”

Sachiko Katsuragi couldn't help crying, she had always thought that her parents were dead, but she didn't expect her boyfriend's stepmother to be her mother. However, when I found out about it, my mother was arrested for killing her boyfriend's father. And the reason why the mother killed her boyfriend's father was because the boyfriend's father killed her father.

If she didn't know these things, the relationship between Sachiko Katsuragi and her boyfriend Takazen Tsujimura was still very good, and after knowing these things, she didn't know how to get along with her boyfriend.
