"From this perspective, the person who sprinkled poison powder on the door handle of Yulang's room should be the wife."

Takagi said in the ear of Officer Megumi: "There are also some poison powder left on the floor under the door handle, and the length of the interrupted part below is exactly the same as the width of the wife's slippers."

"So that's it." Kogoro Mouri pondered: "Because I can't stand the fear of 'I don't know when I will be killed', so the lady took the initiative."

"How is that possible!" Miharasa subconsciously said.

Officer Megumi agreed: "Maybe it's really like you said, it's really difficult to exchange slippers that others are wearing with slippers that are stained with poison powder."

Takagi Suk said: "By the way, there are also Chinese dictionaries that fell next to the wife's body, and the poison reaction was also detected. However, the poison was only at the bottom left side of the expanded side of the book.

And in the box containing the dictionary, I found a bag full of poison powder sticking on it. The bag was a little broken. Maybe someone hid the poison powder in advance, but the bag was damaged for some reason, which caused the dictionary contained inside to be covered with poison powder."

Kogoro Maori thought for a while, "If you say so, the person who hides the poison powder inside is probably the wife."

Officer Memu nodded, "That's right. The lady first poisoned her son, and then hid the bag of poison powder in the dictionary box. Although it was the stepson brought by the president, the son was the son after all. After killing his son, he had the idea of ​​regret. Therefore, he ate the poison powder spilled out of the bag and committed suicide. This is also possible."

His rare reasoning convinced himself a little.

Takagi Suk said: "So, the reason why the wife did not participate in the on-site investigation is..."

"I had already made up my mind to commit suicide when I was alone." Kogoro Mouri shook his head.

Conan couldn't help but say, "Has nothing really been detected on the other items on the table?"

"The toxin was not detected." Takagi nodded, "The contract and eye drops were also investigated on the instructions. There are no particularly difficult Chinese characters."

Hattori Heiji held his chin, still confused, "Who is the one who sent that letter from the beginning and called me to the home of the president in Osaka, deliberately making people notice the shadow diamond tromage, who is the one who was there?"

"Maybe it's a test you took, my wife might have used." Kogoro Mouri said indifferently: "If you, a detective who is considered a very capable person by the president, cannot solve the mystery, and you won't worry about seeing through that trick of typos.

As he said that, he smiled proudly, "But she never dreamed that you would bring me, the real detective, over here this time."

Hattori Heiji curled his lips and said, "If that were the case, would she still deliberately kill someone in front of this famous detective and show you?"

Kogoro Mouri was so embarrassed that he was angry: "How could I know this! Maybe it was because the poison had been spilled, so I couldn't stop!"

"Hey, it doesn't matter what happened. Since we are sure that the vice president is the murderer, then we can go back, right?" Fujiwa Junsheng had his eyelids drooping. He was already unshaven and looked ungrateful. He went through some twists and turns tonight, like a decadent dog that was hit by life.

Satake Yoshio looked at his watch and said, "It's almost time for the last tram."

"I also want to discuss future events with my wife," Shiina Masahisa said.

"It's okay for me, I can stay and cooperate with the investigation." The female butler, Sabuko Yorihara, said seriously.

Takagi Sato said embarrassedly: "Because I have to ask you about the detailed situation before the wife passed away, so I still want to ask everyone to stay and cooperate with our investigation."

...

The crescent moon is like a hook, and the branches and leaves in the courtyard are rustling.

By the window.

"Kudo, Tuoka, do you think that lady is the murderer?" Hattori Heiji frowned.

"I believed in this before until I walked into the study where my wife passed away." Conan said.

"The same is true for me," Hattori Heiji said. "It is hard to imagine that a person who is determined to be dying will ask for a new tea and use eye drops."

Conan nodded, "And the signature on the contract was just written, and there was no intention of inserting the pen cap back."

"That's to say, the lady was sneaked in while signing her autograph, and no one noticed it. She was like a ghost guy who was killed with poison in silence." Hattori Heiji rubbed his eyebrows.

"Have you ever been to the bathroom?" Chen Xing leaned against the window frame and suddenly spoke.

"Ah?" The two people on the opposite side were stunned. They didn't know why he suddenly asked this, but they still shook their heads.

I have racked my brains to solve the case, but I really don’t feel like going to the bathroom.

"There are slippers in the bathroom," said Chen Xing.

"What?" Conan was puzzled first, then his eyes moved.

"You mean, do you need to change slippers if you go to the bathroom?" Hattori Heiji obviously thought of it.

"That's right." Chen Xing said: "I just asked Xiaolan and Heye. When they went to the bathroom, they met Mr. Yulang and washed their hands and came out."

Conan said slowly: "So, the poison powder sprinkled on the door handle of Mr. Yulang's room..."

"It's a trick." Hattori Heiji breathed out.

"But, at that time, there were obviously two annual ring cakes on the tray. How could he take away the poisonous piece from the annual ring cake with the same appearance?" Conan fell into deep thought.

"Is it possible that I read it wrong?" Chen Xing said to himself.

"How is it possible? The butler clearly cut it into nine equal parts." Hattori Heiji smiled, but he immediately froze. "Wait, have you seen it wrong?"

Conan smiled, "So that's it."

Hattori Heiji laughed and said, "I said Tuoche, you actually discovered clues tonight than Kudo and me."

Chen Xing thought of the text message sent by a guy who was probably dreaming about it just now, and he just smiled it, because there were more than two detectives involved in finding the truth tonight.

He was resentful, so he wanted to find a way to kill people.

As for Toru Amuro’s help, well... the boss’s task is just.

...

Next, Conan and Hattori Heiji were all working hard, probably because they refused to admit defeat and actually made a guy who was not a detective take the lead.

At one o'clock in the morning, Chen Xing, who had been sniffing for a while, opened his eyes and saw the two detectives who were a little tired but couldn't hide their confident smile.

They stopped Officer Megu who was about to withdraw the team and called everyone to the living room where they had eaten cakes before.
