"You said you already know who the murderer who poisoned that fool's son?"

"And how the murderer can get Mr. Yulang to eat the poisonous cake?"

"Isn't that the vice president's murderer?"

"Yes, the vice president sprinkled poison powder on the door handle of Mr. Yulang's room in advance, so Mr. Yulang, who had poisoned the poison powder on his hand, took the annual ring cake and ate it, right?"

Satake Yosuke and others stood at the door, looking at the confident detectives in the room without any slightest concealment on their faces.

"In addition, poison powder has been detected from the slippers worn by the vice president, right?" Shiina Masahisa said.

Yorihara Saki retorted: "Isn't that what was left on the slippers when the poison powder was sprinkled on the door handle?"

"That's a trick." Hattori Heiji shook his head and smiled.

"A trick?"

"That's right, this is to blame the wife and finally let her commit suicide. It was a move arranged by the murderer in advance." Hattori Heiji said lightly.

Officer Meguri hurriedly said, "You mean, Madam, she did not commit suicide but murder?"

"That's right, and it must be the same murderer." Hattori Heiji said with great affirmation.

"What about the evidence?" asked Kogoro Mouri.

"Because Mr. Yurang went to the bathroom to wash his hands not long before he got the annual ring cake." Conan said: "Even if he was stained with poison powder when he walked out of the room, it had been washed off."

He Ye Fusheng said, "That's right, I saw him wipe his hand with a handkerchief."

Kogoro Mouri frowned, "But it is not that easy to get the wife to wear slippers stained with toxic powder?"

"It's the bathroom. Those slippers should have been dropped when the wife was in the bathroom." Hattori Heiji explained: "Someone changed the slippers of the wife in front of the bathroom door and the slippers with toxic powder on them."

When everyone suddenly realized it, they also thought of the details of the neglected bathroom.

Juno Fujiha couldn't help but say, "How did the murderer ask that fool's son to get that piece of poisonous cake by himself?"

Yorihara Saki asked, "If Mr. Yuro's hands were not covered with poison powder at the beginning, would there be any other way?"

At this time, Chen Xing pushed a small dining cart over.

"It's very simple." Conan smiled, "because the annual ring cake is placed where Mr. Yuro can't help but take it, let alone if he's hungry."

When Kogoro Mouri heard this, he roared, "Idiot! At that time, the annual ring cake was divided into nine equal parts, and each piece was the same size. What's the use of just changing the placement?"

"Uncle, come and try it." Chen Xing said, letting go of his body to signal.

Two sliced ​​annual ring cakes were also placed in the tray on the dining car.

Conan said: "Yes, uncle will try it myself, so take it with Mr. Yulang's hungry mood."

"Come on the feeling of hunger." Kogoro Mouri walked over suspiciously, but his mood, which he had no concerns, suddenly skipped a beat when he saw the cake in the tray.

"Wait for a moment, it's obvious that the cake placed inside is bigger!"

"Really," said Takagi Shuo next to him, "If this is the case, if a hungry person, he will intuition get the piece inside immediately."

Kogoro Mouri said a little dissatisfied: "I just said that the two annual ring cakes are the same size. Why are you making trouble with these two little kids?"

Hattori Heiji rolled his eyes, am I a little devil?

Chen Xing shook his head, "It's true, this is the annual ring cake prepared by the police just now to investigate the scene. I'll borrow it."

"How is that possible?" Kogoro Mouri didn't believe it, so he picked up the smaller cake close to him. "As long as you fold it, the big one will be obviously..."

Before he finished speaking, the detective glared at his eyes because the two annual ring cakes folded by him were clearly the same size.

"The same size? What's going on?"

"This is the Chestero illusion," Conan said.

"What?"

"When people use their eyes to compare, they will generally involuntarily choose the closest sides to compare. Therefore, if they are scattered together, they will involuntarily compare the long and short sides."

Conan said: "So, even though it is the same size, you will mistakenly feel that the piece inside is larger."

Hattori Heiji nodded, "Yes, this is a kind of visual illusion discovered by psychologist Chestero a hundred years ago."

"So that's it." Takagi Shiro suddenly realized, "The murderer placed the poisoned annual ring cake in a larger place and asked Mr. Yuro to get it himself."

Kogoro Maori said, "But if you use this method, Miss Mis. Mis. Mis. Satake, who were responsible for cutting the annual ring cake and putting the tray on the tray, as well as Mr. Fujihara and Mr. Shiina who were standing next to the cake tray at that time, can only do it without realizing it?"

Hattori Heiji chuckled, "But, among the four of them, there is only one of them who has the means to poison his wife."

"Now, let's go and see the study where the wife was killed." Conan waved his little hand.

...

study.

"What the hell is going on? I thought the mystery was about to be solved, but what did we do when we saw this kind of picture?"

Kogoro Mori, sitting at the desk, looked at the computer screen speechlessly, with the words of the company brand name that kept flashing.

"Look clearly, there are 50 styles." Conan said with a smile.

Hattori Heiji said, "Before Mrs. Wakamatsu passed away, did you see this picture?"

"Yes." Fujiha Juno and others answered.

Kogoro Mouri pinched the bridge of his nose in depression, looking a little tired.

"Are you tired?" Conan blinked.

Kogoro Mouri was furious, "Nonsense! Why do you keep making me see such a flashing thing?"

Conan took out his ears, then took out a small notebook from his pocket and handed it to him, "Then can you write Ruosong's word "Ruo now?"

"Ah?" Kogoro Mouri looked confused, and he didn't understand what this guy was doing.

But can such simple Chinese characters be difficult to get his famous detective?

The answer is yes. The rather disdainful Kogoro Mori took the paper and pen, but after only writing the word "花" in the pen, the tip of the pen stopped. He thought hard and couldn't remember what the next stroke was.

"It's strange." He scratched his head and secretly glanced at the computer screen.

"Uncle, you can't cheat." Conan switched the desktop casually, "Because Mrs. Wakamatsu is not used to using this computer, she shouldn't be able to open this document."

Kogoro Mouri's face heated up, and he immediately asked Takagi Shigeru next to him, "Takagi, what's under the word "草"?"
