Rebirth of Conan as a Detective

"What?" Tokyo and Hattori's eyes widened immediately after receiving the call from Gao Cheng, "Son?! Are you sure?"

"There is nothing wrong," Gao Cheng looked at Dahe Daozhu next to him, and continued to make phone calls, "We will talk about the specific situation later, there is not much time left, Mrs. Wakamatsu may be killed after Mr. Ikuro , now only you can stop it!"

"what is the problem……"

Before Hattori Conan could figure it out, his face changed and he looked towards the direction of the study.

"Then," Mu Mu finally walked to the doorway of the study room, "I will let two policemen stand by the door of the room, if there is anything, please tell them."

"OK."

Mrs. Ruosong watched Mu Mu leave wearily, and after the door was closed, the surroundings suddenly became deserted. After a moment of silence, Mrs. Ruosong's tired face disappeared, and she couldn't help laughing.

"etc!"

Hattori Conan suddenly opened the door at the same time and rushed into the study, looking at Mrs. Wakamatsu with a frozen smile.

Just now, they had asked the forensic personnel to check the place where the victim's fingers might touch, and found poison residue on the doorknob outside the victim's room, and the prisoner accidentally spilled it on the floor and his own slippers. I plan to let the police check everyone's slippers.

Hattori rolled his eyes.

"What the hell is that Kido guy doing? No matter how you think about this lady..."

"It should be said to be a crime of covering up," Gao Cheng's voice continued to ring on the phone, "or there are other crimes, but the murderer is not her."

"what?"

Hattori turned on the hands-free, and roared sullenly, "Then tell me why?!"

"I've been wondering why someone sent you that letter and reminded you of the secret of the tile exchange at Wakamatsu's house in Osaka, and why a homicide happened when you came to the door, or why the prisoner knew in advance that a detective would come to the door, but Still want to kill Mr. Ikuro..."

Gao Cheng rubbed his ears and explained: "There are two possibilities. The sender hopes that you can find the murderer who killed the president, and the sender hopes that you can prevent Mr. Yulang from being killed. The premise of these is that the sender is not the one who killed Mr. Yulang. The murderer, as you think, Mrs. Ruosong killed someone."

In the study, Mrs. Wakamatsu's expression froze with a froze expression, and her expression gradually turned into astonishment.

Others also gathered together.

"What's wrong? Don't you want to restore the scene?" Director Shiina asked doubtfully.

He Ye heard the voice and asked: "Is it a call from Kido?"

"Kiroto?" The secretary and maid looked blank, "Who is Kido?"

"It's Takasei Kido, who is as famous as my father," Xiaolan explained with a smile, "Senior Kido went to Karuizawa to investigate the scene where President Wakamatsu was killed."

"Hmph." Mori Kogoro stretched his face in dissatisfaction.

They all ran to Karuizawa, and even came to intervene in his case...

"Thinking of Mrs. Wakamatsu as the murderer who killed Mr. Ikuro, on the surface it seems correct, because she was the one who covered up Mr. Ikuro at the scene of the president's murder. I'm afraid she was hiding at the scene with the murder weapon..."

Gao Cheng's voice rang clearly in the study through the phone, as if bringing everyone back to the scene of the first incident.

"For some unknown reason, Mrs. Wakamatsu not only dismissed the maid and hid the news of the death, but also took the opportunity to let Mr. Ikuro hold the president's body and cry, so that blood stains on his body would not be suspected. Of course, the murder weapon was disposed of separately. Afterwards it was decided to remodel the bathroom to completely eliminate the traces, and no one would have thought that the tiles were actually visually deceiving..."

Hattori frowned and said, "Maybe you don't know if you're not here. We have found clues. The murderer sprinkled poisonous powder on Mr. Ikuro's doorknob. It seems that his own slippers were also stained. Just check everyone's slippers..."

"If you secretly replace it, you can set the blame on it."

"How can this kind of thing be done? Can do this kind of thing without being suspected..."

"Outside the toilet."

Gao Cheng checked in the bathroom of the villa and said: "There are slippers in the bathroom of the Karuizawa villa. I think it should be the same in Tokyo, right? And most importantly, since Mr. Ikuro likes to eat cakes with his hands, normally , it is possible to wash your hands beforehand, even if only once, it will lead to the failure of the prisoner's plan...

"Or Mr. Ikuro never had this habit?"

"This……"

Hattori's complexion changed, and he looked at the Wakamatsu family.

"By the way," He Ye recalled, "At that time, Xiaolan and I were going to the bathroom, and Mr. Ikuro just came out of the bathroom, and then went to the living room, and asked us, 'I heard Mr. Shiina's voice. Bring Baumkuchen?', and said while wiping your hands!"

"W-how did this happen?" Hattori and Conan looked at each other, sweat dripping from their faces.

"Doesn't it mean that the cake was poisoned?"

"But at that time, there were two Baumkuchens in the tray, both of the same size and shape. How can I let that idiot young master...Mr. Ikuro get it? Is there really such a way?"

"Of course there is."

Gao Cheng held his mobile phone and said with a smile: "Have you forgotten? It is an optical illusion that has been used several times. You only need to display the two vintage cakes according to the situation at that time. The reason why Mr. Yulang chose the second piece s reason."

"Gastro's illusion," Zhu Fu Gaoming, who had been silent beside him, suddenly said, "Is Detective Kido talking about an illusion discovered by a psychologist named Gastro more than 100 years ago? Indeed, because the baumkuchen It is a ring shape, and if two pieces of eight equal parts are placed in parallel, even if the size is the same, there will be a contrast due to the different lengths of the inner and outer arcs, and the result is that the inner piece looks bigger..."

"Well, that's about it..."

Gao Cheng looked slightly startled.

He just analyzed the scene of the crime through his thinking space, and the facts are the basis for judgment.

"In short, the only ones who could use this method were the maid who cut the cake, the secretary who served the tray, and the designer Fujinami and Director Shiina who were standing by the tray at that time."

Gao Cheng said with serious eyes.

"And only Mrs. Wakamatsu, who has never been close, will be ruled out by the police. At the same time, you, a famous high school detective, will also be suspected. I think the real murderer will probably secretly remind you that there is poison in the doorknob, and guide you to point the target at Mrs. This is also the reason why we have to do it today.

"Look at the panic you all had just now. Did Mrs. Wakamatsu stay in the room alone? If I guessed correctly, she would probably commit suicide soon. Maybe the suicide note was prepared, although I still don't know what the prisoner will use. method, but I’m afraid it’s about letting Madam poison herself to death.”

"You mean that the murderer this time is the sender?" Hattori looked at Mrs. Wakamatsu, who was already pale in the study, "Why?"

"Revenge plus silence," Gao Cheng said calmly, "Of course it's just my guess, but Mrs. Wakamatsu probably doesn't want Mr. Yulang to live anymore, so this can explain the reason for deliberately staying away when sharing the cake. Maybe Mr. Yulang's death is early. Just as she expected."

"she knows?!"

Hattori frowned.

Come on, why is Kido so clear? Obviously not there...

Could it be hiding somewhere?

Hattori looked around suspiciously.

"It's strange, isn't it?" Gao Cheng continued, "Why does the murderer know about the tiles? He has never been to the scene, but he seems to know that Mr. Yulang is the murderer who killed the president. Either the murderer found out the truth himself, or Someone tipped it off to the killer."

Hattori looked at Mrs. Wakamatsu with an ugly face and cold sweat, so there was no need to verify it.

Who is the murderer? !

Mu Mu couldn't help asking: "Brother Chenghu, who is the murderer..."

"There are 4 suspects, but they can arrange the time for the guests to visit, and make the number just enough to make eight equal parts of the Baumkuchen." Gao Cheng looked at the time on his watch, "There is only one person."

"Secretary, Ms. Satake?!"

Everyone at the scene froze except Mrs. Wakamatsu, and even the pupils of the secretary Satake who had been calm all the time suddenly dilated.
