Conan: Another Famous Detective

Afterwards, Hattori and Conan left with Yonehara, while Akira Hanomiya stayed to continue questioning.

Anyway, with two more people taking action, they can probably find any clues no matter how hidden they are, so there is no need for him to join in the fun.

Moreover, according to his vague memory of the plot, it seems that Zuo Zhu in front of him is the murderer of this case!

Therefore, he planned to test Zuo Zhu to see if he could find any flaws.

So, he asked: "Excuse me, Miss Zuo Zhu, when you and Miss Yonehara were cutting the cake, did you notice that anyone except you two touched the cake?"

Zuo Zhu shook his head: "No, I remember that neither of them had ever been close to the cake at that time."

"Well..." Yu Gongming pondered for a while and continued to ask: "So, how is the relationship between Mr. Ikulang and you guys?"

Zuo Zhu replied: "In general, although personally I don't like Mr. Yulang's character, but I am just a secretary, and I actually have nothing to do with Mr. Yulang."

"But Mr. Ikuro is usually a little informal, and sometimes brings some trouble to Miss Yonehara who cleans the house, so Miss Yonehara is a little dissatisfied with him."

"As for Mr. Shiina and Mr. Fujinami, Mr. Shiina is not sure. Mr. Fujinami seems to look down on Mr. Ikuro very much."

Yu Gongming nodded and suddenly asked: "By the way, what time is it now?"

Zuo Zhu subconsciously raised his hand and looked at his watch: "It's already eleven twenty."

Yu Gongming watched Zuo Zhu's expression and gradually understood.

Then, he asked a few more innocuous questions and ended the inquiry.

At the same time, Conan and others also returned to the living room.

"How is it?" Yu Gongming asked with a smile.

"We've figured it out." Hattori Heiji smiled: "We finally understand how the death message disappeared at that time!"

"Tell me."

"It's the [crazy diamond] phenomenon." Conan laughed.

"Crazy diamond?" Akira Hanamiya muttered this English phrase, searched in his mind for a while, and confirmed: "Are you talking about the phenomenon of shadowed diamonds?"

"That's right! That's it!" Hattori Heiji smiled.

"Hey! What diamond...are you talking about?" Officer Megure asked in confusion.

Conan explained: "The shadowed diamond optical illusion. Commonly known as the "crazy diamond", that is, the angles of the upper and lower corners of each rhombus are between 30 degrees and 40 degrees, although only a little wavy method is used on the rhombus plane. , but the human eye will still regard the shades of adjacent boundary lines as visual focuses one by one."

"Because only one part is looked at, the whole thing is visually mapped. The upper rhombus and the lower rhombus seem to become different colors. In other words, this is an illusion caused by the brain's calculation error. .”

"Um, I still don't quite understand..." Officer Megure felt a little embarrassed.

"In short, in the bathroom where President Wakamatsu was killed, it seems that the colors of the upper and lower tiles are different. In fact, it is just the principle of shadowed masonry trompe l'oeil, and the color of the tiles is the same."

"The disappearance of the death message at that time should be due to the murderer simply wiping the blood stains and then replacing the tiles with remaining blood stains with clean tiles."

"I probably understand. So, is this the same principle behind the disappearing text that Kazuha saw at that time?" Mouri Kogoro finally understood.

"That's right." Hattori nodded: "Didn't Kazuha say that after the text disappeared, there were traces of something scratching the tiles under the wall? This is evidence that the tiles were exchanged!"

"So, the person who sent you a letter to lead you to a villa in Osaka just wanted to remind you of this?" Akira Hanamiya said meaningfully.

"Yes! But I don't understand why that guy told me this technique?" Hattori said in confusion.

"It's better to contact the Nagano Prefectural Police. If we can get the death message from them, we might have some ideas."

"Um... I remember that Kazuye seems to have the contact information of the Uehara police officer in Nagano?" Hattori looked at Kazuye and asked.

"Yes! I'll contact you right away!" He Ye said, already taking out his cell phone and starting to dial.

After a while, the call was connected: "Hello! Is this Miss Yui? I'm Kazuye..."

After the two exchanged pleasantries for a few words, they got to the point.

"Miss Yui, are you responsible for the murder of President Wakamatsu of Karuizawa Villa?" Kazuha asked.

"Yeah, now A-Gan and I... Well, Officer Yamato is investigating in that villa! What happened? Do you have any clues?" Yui asked doubtfully.

"Well! Let Heiji tell you about that!"

Kazuha handed the phone to Hattori Heiji.

Hattori finally put his cell phone to his ear: "Hello! Hello, Officer Uehara..."

Afterwards, he informed Yui of the situation here and the optical illusion with the Yin-Yang Diamond.

Hearing this, Yu Yi asked with a slightly excited tone: "Are you really sure?"

"Well! Based on the current clues, I think this is the most likely possibility!" Hattori said confidently.

"Okay! I'll tell A Gan right away. If I find any news of death, I will notify you immediately!" Yu Yi said and hung up the phone.

Hattori smiled and said: "We can just wait for now."

About half an hour later.

He Ye's cell phone rang again.

Hattori immediately answered the phone.

"Hey! Are you the detective boy from Osaka?" A rough voice came from the other side.

Hattori Heiji was stunned for a moment, then realized: "It's Officer Yamato!"

"Well! According to your method, we have found the death message!" Officer Dahe said with a smile, looking very good.

Officer Yamato is indeed quite happy now.

Just when Yui told him Hattori's reasoning and he was directing forensic personnel to conduct an on-site inspection, his old rival Morofuku Gaoming also came to the scene!

According to Zhufu Gaoming, he had been transferred back to the headquarters, and as soon as he arrived at the scene, he pointed out the phenomenon of shadowed diamonds in the bathroom.

Fortunately, he already knew this technique. As soon as the other party got up, he interrupted him directly, told him about the phenomenon, and even ridiculed him.

When he thought of Morofuku Gaoming's gloomy expression just now, Officer Yamato couldn't help but want to laugh!

Hattori naturally doesn't know the cause and effect here. He only cares about the content of the death message now.

He asked with some urgency: "What exactly is that death message?"

Officer Yamato seemed to understand his mood and said with a smile: "It's [s] [o] [n], which is [son]."

Hattori's expression changed instantly: "You mean... son?"

"That's right!" Officer Yamato said: "If I guess correctly, this [son] should refer to his son Wakamatsu Ikuro!"
