Conan: This repairman is not very knowledgeable

"Officer Megure."

"I think the facts are obvious."

Uncle Maori straightened his collar, glanced at everyone present, and prepared to start reasoning.

"Brother Maori, are we going to start right away?"

Inspector Megure was even about to ask Takagi to bring a chair over.

Not sleeping today?
"Because she couldn't stand the fear of being killed at any time, the president's wife decided to take the initiative."

Uncle Maori nodded and pointed out that the recently deceased Wakamatsu Serika was the murderer of Wakamatsu Ikuro.

The police found poison powder on Wakamatsu Ikuro's door handle, and there were also spray residues on the floor at the door and on the slippers worn by Wakamatsu Serika, which was evidence of poisoning.

"Also, the Chinese dictionary next to the lady's body was tested and found to have a toxic reaction, but the poison was only found on the lower left side of the book."

"Inside the box containing the dictionary, a bag filled with poison powder was found, but the bag was damaged."

"Maybe someone hid the poison powder inside beforehand, and the bag was damaged, causing the native language dictionary to be stained with the poison powder."

Takagi added a survey result.

"The person who hid the drug powder is most likely the president's wife." Uncle Maori reasoned.

"She first poisoned her son and then hid the bag of poison inside the dictionary box."

"Although he was the stepson brought by the president, a son is still a son after all. After killing him, she felt regretful and therefore took poison and committed suicide." Inspector Megure also followed this line of thought and nodded.

"Wait a minute, Brother Lin Feng heard it. The president's wife was laughing alone in the study." Hattori hurriedly called for a stop. He still found it strange that the other party would suddenly commit suicide.

"what?"

"It's also possible that after killing the person, he gave a bitter smile or something like that." Uncle Maori looked at the repairman.

Or maybe there's the situation where you laugh and cry at the same time. Isn't this kind of plot common in TV series?

In short, considering the content of this letter, there is no doubt about the president's wife's motive for murder, and poison reaction was also found on her slippers, which can be used as evidence.

"That laugh sounded like a conspiracy was successful."

"Just like a few days ago when you lied to Xiaolan and said you were going to meet the client, but in the end..."

Lin Feng was halfway through his words when Uncle Maori immediately rushed over and tried to cover his mouth. Of course he failed, but the repairman still stopped talking.

"What did you do in the end?"

"Dad?" Xiaolan asked with a smile, clenching her fists.

He went out to meet a client and applied for some funding from himself, but in the end the business was not concluded and he came back drunk.

Now that I think about it, there is no client who would ask a detective to treat him to a meal...

"Ahem, it's better to get this case cleared up first." Inspector Megure coughed lightly.

"Yes, I roughly know what kind of laughter it is." Uncle Maori's expression also became serious.

If it was the kind of laughter that came from a successful evil plot, then it was something that needed to be reconsidered.

"Officer Takagi, have all the items on the president's wife's desk been inspected?" Conan asked, looking up.

"Yes, no poison was found in the eye drops, pens, documents to be signed, and black tea." Officer Takagi nodded.

These four items were given to Wakamatsu Serika by the four surviving suspects.

"Then, could it be that someone deliberately poisoned that native language dictionary?" Sera said after thinking for a while.

"You heard it, right? The president's wife passed the first-level Chinese character certification exam. Logically, she would never touch a dictionary."

"If you want to kill someone, you should find another place to poison them." Uncle Maori retorted, shaking his head.

Who would poison a place like that...

"I'm afraid we can't be sure now that the president's wife is the murderer of Mr. Ikuro." Amuro said with a smile.

"It's impossible that this letter was forged by someone else. It will be exposed if the handwriting is compared." Inspector Megure said as he showed the confession in his hand.

This motivation is sufficient.

Moreover, poison powder was also detected on the slippers.

"If the murderer is someone else, how should the pair of slippers be exchanged? Give the pair with poison powder to the president's wife." Conan kept thinking in his mind.

"Do you want to go to the toilet?" Lin Feng asked, patting the dog's head who looked thoughtful.

"???"

Conan blinked.

What does it mean, why do we need to go to the toilet.

Shall we go together?

"Manager, have you noticed it too?" Amuro said, touching the dog's head.

It feels good in hand.

"What are you talking about?" Hattori looked puzzled.

"There are slippers in the bathroom of this villa, right, Miss Mihara?" Lin Feng looked at the housekeeper standing at the door.

"Yes, there are special slippers in the toilet." Sakurako Yonehara nodded.

People usually leave their slippers at the bathroom door and then change into special slippers...

"I see. This way we can exchange slippers without arousing suspicion from the other party!"

After the other party said this, even Uncle Maori understood what was going on.

The slippers evidence has found a loophole.

"This case is really complicated..." Inspector Megure looked at the letters in his hand, wondering how much of it was true.

"Excuse me, when can we go back?" asked designer Mr. Fujinami after checking the time.

After investigating over and over, there was still no clear clue, and it was almost midnight.

"Actually, I should go back and discuss what to do next with my wife." General Manager Mr. Shiina also nodded.

What he said made sense. First the president died, and now the vice president who was barely able to support the company has also died. When you reach middle age, it is impossible not to consider the next step.

"It's a headache. It's almost time for the last train." said the secretary, Ms. Satake.

After the three of them expressed their opinions, seeing that everyone was looking at them, the housekeeper, Miss Yonehara, immediately said, "It's okay with me. I can stay and cooperate with the investigation!"

Not to mention how much kindness the deceased president had shown her, now that all three members of her family have passed away, she will definitely lose her job...

"I still want you to stay for a while. There are still many suspicious points in the lady's death." Inspector Megure shook his head and rejected the three people's request to leave.

One by one, they are dying right in front of you. What are you guys thinking about? Go home and sleep?

……

The study where Wakamatsu Serika died.

"There must be some reason that made her look up the dictionary!" Hattori put on white gloves, stood in front of the table, and said with a frown.

Level 1 Chinese character certification.

Very powerful.

"The police have checked the contract to be signed, including the instructions for the eye drops, and there are no particularly difficult Chinese characters."

Conan stood nearby, unable to figure out what was going on for a moment.

"The two of them are inseparable, just like a pair of partners." Outside the door, Amuro looked at the performance of the two, one big and one small, and spoke.

"Yeah, it seems that Conan is not like a child at all when facing a case." Sera saw something different.

"What is that like?"

Lin Feng wanted to hear her story. "A detective, and a very good and famous detective!" Shiliang looked at Lin Feng and said with a smile.

Stop pretending. As the manager of a coffee shop, you must have other identities as well!

"Now that you mention it, Conan is a bit outstanding." Amuro folded his arms, thought about Conan's performance in daily life, and nodded.

It is said that he always watches detective movies and plays detective games at home...

I feel that he is even more perceptive than my Maori teacher.

By the way, why isn’t Mr. Maori sleeping today?

"Mr. Lin Feng, you have spent more time with Conan, have you felt anything?" Shira checked the situation.

"I feel that Conan has a big head." Lin Feng commented.

"..."

"Hey, calm down. Those two guys outside seem to be watching you." Hattori bent down and reminded in a low voice.

Pay attention to your expression and movements, you are a child...

Conan turned around when he heard that and indeed found that three people, including Lin Feng, were staring at him at the study door.

"Oh my, Heiji-nii, it seems like this computer is always on!"

Being watched, Detective Doghead could only use this method to ask Hattori to check the computer.

"Yes, really? Let me see!"

Hattori laughed awkwardly, rubbed Conan's head, put on white gloves, and looked through the contents of the computer.

You are really amazing, Kudo...

I may never be able to catch up with you in this life...

"This child..." Amuro looked at the elementary school student with an innocent smile on his face and suddenly felt a little dazed.

The detective game suddenly ended???

"Hehehe..." Sera looked at Conan, who had a big head, with a smile on his face.

It was like a switch to avoid danger was activated!
"Have you two found out the truth?" Lin Feng glanced at the two guys who looked like nothing had happened.

The two people inside are working hard to investigate the case, but you two are standing at the door, as motionless as wood.

"There are still many questions, but I can roughly guess who the murderer is." Amuro said with a smile.

"Oh?"

"I have no idea at all." Sera looked at the other party in surprise.

"Since the president's wife is not the type who would commit suicide, we should think carefully about why she left such a letter." Amuro said with a smile.

"Aren't you staying here because you're afraid that you'll be killed by Mr. Ikuro?" Sera's eyes were full of doubt.

"Since you are afraid of being killed, you have to take the initiative." Lin Feng saw that the expressions of the two people in the room changed. They might have found something on the computer.

The president’s wife is not a simple character. Would she leave a letter and then do nothing but wait for death?
This is obviously impossible.

Amuro is also the type who understands people's hearts very well, and he figured out the details from this perspective.

"Mr. Lin Feng, your angle is very unique." Shiliang felt as if something had suddenly dawned on him.

"..."

Amuro glanced at Lin Feng secretly.

Yeah, our store manager is weird, but I can't find out anything.

"Oh, that's so strange!" A strange voice came from someone's mouth in the study again.

His voice successfully attracted several people to the computer.

Hattori felt cold all over after hearing this and looked at the other party with respect. "I think the mystery has been solved, but now we are still missing the most important evidence."

"I have found the evidence." Lin Feng said after looking at the computer screen.

"what?"

The other four people looked at the repairman with puzzled eyes.

……

"Inspector, there are no details that have been missed." After questioning several suspects again, Takagi finished taking notes and reported to Officer Megure.

"I really don't understand how the murderer got the president's wife to get the dictionary." Uncle Maori, who had been eavesdropping, raised the question.

Who would flip through this kind of reference book for no reason?

"Oh." Inspector Megure sighed slightly.

Can't figure it out?
If you can't figure it out, just go to sleep, Maori brother...

"Inspector Megure, please gather everyone together. I have found out the truth."

Just as Inspector Megure was about to go home, Hattori knocked on the door and walked in.

"Really?" Fatty Orange immediately perked up.

Sure enough, with so many people present, there must be one or two who can do it...

……

In the study, reasoning begins.

"First, the method used to poison Mr. Ikuro," Hattori said with his hands in his pockets as he looked at everyone present.

"Didn't the murderer sprinkle poison powder on the door handle?" Uncle Maori looked curious.

You can skip this step directly.

"Yes, it is true that the poison powder was spread, and it is also true that Mr. Ikuro had some of it, but I think it should be more than that."

As soon as Hattori finished speaking, Conan pushed the food cart and walked into the study.

On the plate on the dining cart, there were two pieces of cut Baumkuchen cakes. They were bought by the police for comparison and were not evidence.

"What do you mean?"

Uncle Maori was puzzled. The poison had already been swallowed, so what was the problem?

"What he means is that the murderer not only poisoned the door handle, but also poisoned the cake for safety reasons," Amuro explained.

This can probably be considered as a layer of insurance.

"But we didn't find any poison ingredients on other cakes." Inspector Megure didn't understand how the other party could accurately put the poison on the cake that Wakamatsu Ikuro was going to take.

"Now there are only two pieces of cake on the plate, just like the situation back then. Uncle, just imitate the dead and choose one like a hungry wolf!" Hattori pushed Uncle Mori to the front of the food cart.

"Ask me to choose..."

"Hey, that Baumkuchen cake was cut into eight pieces, and each piece was the same size. Your two pieces are obviously different sizes, right?"

The two cakes were placed one in front of the other, and Uncle Maori pointed at the one farther away from him and said.

"When people compare sizes with their eyes, they generally tend to use the two closest sides for comparison."

“So, if you compare fan-shaped things like Baumkuchen together, you will involuntarily compare the long side with the short side.”

“They are clearly the same size, but one mistakenly feels that the inner piece is larger. This is the Jastrow illusion.”

Conan stood on tiptoe, stacked two pieces of cake together, and explained science to everyone with a smile.

Of course, he did not forget to tell everyone that this was what his brother Heiji told him.

"So that's how it is. They really planned this out." Uncle Maori saw that the two cakes were exactly the same size and couldn't help but glance at the four suspects.

The four men were not far from the dining car at the time and had the opportunity to commit the crime. (End of this chapter)
