My neighbor's name is Conan

Chapter 887 The murderer took double insurance and was determined to kill Mr. Yulang

The question is, how did the other party sprinkle the poison powder on Wakamatsu Serika's slippers?

The shoes were worn on Wakamatsu Qinxiang's feet. If the poison powder was sprinkled in front of her, Wakamatsu Qinxiang would definitely notice it because she was not blind.

eccentric!

Judging from the circumstances before Wakamatsu Serika's death, someone must have tampered with the contract, dictionary, and pen, but the problem is that, to some extent, all four suspects had the opportunity to tamper with them.

Unable to identify the key suspect for the time being, Aoki Matsu stepped forward to personally examine Wakamatsu Serika's body.

First, there were the opened dictionaries scattered around.

Qing Musong picked it up and looked at it, then said, "The page that the dictionary is open to seems to stop at the part with the sound wa."

Nanatsuki Koshimizu said: "On the whole, the poisoning was most likely caused by Mrs. Wakamatsu wanting to look up a certain word at the time."

Upon hearing this, Qing Musong immediately looked at the contract and found that there was only a stroke on the contract and no further writing was done.

This……

Aoki Matsu remembers that he always signed his own name when signing the contract.

So, logically speaking, Wakamatsu Serika should have written her own name on the contract.

You can’t even write your own name?

impossible!

Aoki Matsu was stunned for a moment.

Maori Kogoro immediately said, "It's possible. The murderer knew in advance that the text contained difficult-to-understand Chinese characters or words, so he set a trap for Mrs. Wakamatsu to look up the dictionary that was poisoned in advance."

Fujinami Junsei couldn't stand it anymore and said quickly, "Hey, wait a minute, I don't think the vice president would not know any Chinese characters."

Satake Yoshimi said quickly, "Because the vice president once passed the first level of the Kanji test. Also, even if you really want to doubt us, can you please read the letter that the vice president left for me first?"

Qing Musong looked at her and asked, "Faith?"

Satake Yoshimi said, "It was a letter that the vice president gave me in advance. She said that if anything happened to her, I should remember to hand the letter over to the police. The letter was kept in the safe in the study."

"Maruta, go get it." Aoki Matsu ordered.

"Yes!" Maruta replied.

It was brought over very quickly.

The content of the letter was Mrs. Wakamatsu's confession.

When she heard that her husband was stabbed in the Karuizawa villa and rushed to the bathroom, she actually saw her son hiding behind the door with a knife in his hand and covered in blood, but she chose to protect her son.

The reason she protected her son was because he had already realized that she was the one who embezzled public funds. In order to prevent him from telling anyone, she asked her son, who was covered in blood, to throw himself on her husband's body to hide the blood splatter. She also forged false evidence to make the police think that it was an outsider who committed the crime, hid the murder weapon, and later helped him dispose of it.

As for the antemortem message written by the president, it was also hidden using an optical illusion. However, perhaps one day when she knows the real murderer, she will be killed by her son to silence him. At that time, she hopes to use this antemortem message as evidence and hand it over to the police.

After looking at the letter carefully, I found that it was indeed written by Wakamatsu Serika and not printed out.

only……

If it weren't for Satake Yoshimi's talk about the contract, Wakamatsu Serika wouldn't have died.

Now is also the first time she has thrown out a new clue.

I always feel like Satake is really leading the police in investigating the case!

Only a very small number of such people are not murderers.

So Satake Yoshimi is suspicious +1!

After thinking for a while, Aoki Matsu looked at Satake Yoshimi and asked, "Are you the only one who knows about this letter as the secretary?"

Satake Yoshimi replied, "It should be. However, since the vice president opens the safe every night, he might check if the envelope of this letter has been opened. Someone might become suspicious."

Yonehara Sakurako responded, "Ah, I did feel that the lady was hiding something. Once when I came into this room to clean, the lady was looking at me in front of the safe, and she told me to knock on the door before entering the room, and she was very angry and blamed me.

But I think everyone else here should have noticed it, because Madam often calls people from the company to this room to discuss company matters together."

Qing Musong looked at the others and said, "So you all should know that this letter exists, right?"

Before they could answer, the detective from the Identification Division came over and reported, "Inspector, we detected a toxic reaction on the dictionary that fell next to Mrs. Wakamatsu's body, but the toxic reaction was only on the lower left side of the unfolded book.

Furthermore, inside the box containing the dictionary was a bag filled with poison powder. The bag was slightly damaged. It is possible that someone had hidden the poison powder inside beforehand, but the bag was damaged for some reason, causing the dictionary inside to be stained with the poison powder as well.”

Upon hearing this, Maori Kogoro immediately said, "It seems that the person who hid the poison powder inside was most likely Mrs. Wakamatsu. Mrs. Wakamatsu poisoned her son first, and then hid the bag of poison powder inside the box. But Mrs. Wakamatsu didn't expect that the bag of poison powder in the dictionary would break and get into the dictionary."

"No!" Aoki Matsu interrupted Maori Kogoro directly, "If Mrs. Wakamatsu put the poison powder there, why would she ask us to get the dictionary? Isn't she afraid that we will find the poison powder in the box?"

"That!" Aihara Yoji said at this time: "Inspector, when I went to get it, the box and the dictionary were separated, so I didn't find it. It was only when the criminal detectives in the forensic department took down the books on the left and right sides of the bookshelf for a drug test that they found it. It was placed next to the dictionary."

He is not a fool. If the dictionary was in the box, he would definitely see it when he took it out.

Qing Musong frowned when he heard this. If that was the case, then he was not sure.

Hattori Heiji also had a question that he couldn't figure out at this time, "Who was the person who received the letter at the beginning, called me to President Wakamatsu's hometown in Osaka, and deliberately made people realize the shadow diamond illusion?"

Maori Kogoro guessed, "Maybe Mrs. Wakamatsu used you as a test. If you, who President Wakamatsu considered a very capable detective for several years, can't solve the mystery, then you don't have to worry about the optical illusion being exposed. However, she never dreamed that you would bring a real detective like me with you this time."

Hearing this, Hattori Heiji said in dissatisfaction: "If that is really the case, would she deliberately kill someone in front of this famous detective?"

Maori Kogoro said angrily: "How should I know? Maybe it's because the poison has already been spread, so we can't stop it."

At this time, Fujinami Junsei suddenly said, "It doesn't matter what happens. Since we have confirmed that the vice president is the murderer, we can go back now."

Satake Yoshimi glanced at his watch and said, "It's almost time for the last train."

Shiina Masafuji also said, "I also need to go back and discuss future matters with my wife."

Yonehara Sakurako was willing to stay. "It's okay with me. I can stay and cooperate with the investigation."

"Mr. Ikuro's death may have been caused by Mrs. Wakamatsu, but the murderer of Mrs. Wakamatsu has not been found yet." Aoki Matsu looked at the four people and said, "We still have to ask everyone to stay and cooperate with our investigation."

Qing Musong ignored the three people and prepared to go to the study to search it personally.

After leaving the living room, Aoki Matsu looked at Koshimizu Nanatsuki and asked, "Koshimizu, do you think so much about this case?"

"The death of President Wakamatsu was probably caused by Mr. Ikuro, and Mrs. Wakamatsu was an accomplice. The deaths of Mr. Ikuro and Mrs. Wakamatsu were probably caused by the same murderer. The method of committing the crime is not difficult, but the difficult part is finding evidence to identify the murderer. If we only look at the method, the four in the room could have done it." Nanatsuki Koshimizu replied.

Qing Musong nodded and said, "I think so too."

The method of this case is not difficult, but the difficult part is finding evidence that can identify who the murderer is.

Seeing that Nanatsuki Koshimizu also had no clues, Aoki Matsu instantly became more confident. It seemed that he was not a loser, but the murderer was cunning.

Aoki Matsu found confidence in Koshimizu Nanatsuki and immediately took people to the study.

But unexpectedly, after walking a few steps, Qing Musong suddenly saw something coming in the corridor.

"Ah!" Aoki Matsu was stunned when he saw this, and then immediately looked at Mao Lilan standing next to him and asked: "Xiaolan, why are there a pair of slippers here?"

Mao Lilan replied: "It's Kazuha's. There are slippers in the toilet. Generally speaking, people will change their shoes."

Qing Musong's eyes lit up when he heard this.

"I see!" Nanatsuki Koshimizu also understood instantly, "If Mrs. Wakamatsu went to the toilet, the murderer could have replaced Mrs. Wakamatsu's slippers."

At this time, the toilet door opened. Yuanshan Heye saw Qing Musong and others and suddenly became shy. "What? People are going to the toilet and you are standing at the door."

Qing Musong immediately asked, "He and Ye Xiaolan, do you remember that Mrs. Ruo Song went to the toilet? Who was not in the living room at that time, and who was not under your noses?"

Yuanshan Heye thought for a moment and said, "Mrs. Wakamatsu didn't go to the bathroom before us. But I remember that the person who went to the bathroom before us was Mr. Ikuro, and after he left, he immediately went to the living room."

At this time, Mao Lilan said, "But I seemed to hear Mr. Shiina's voice. He seemed to tell us that he was going to buy a Baumkuchen or something like that."

"Are you telling the truth?" asked Nanatsuki Koshimizu.

Yuanshan Heye nodded, "Really, I'll talk while I'm intervening."

Mao Lilan also said: "He is still very proud."

"Isn't that strange?" Nanatsuki Koshimizu frowned when she heard that.

[At that time, there were clearly two pieces of Baumkuchen on the tray. How could he take the poisonous one from the two identical-looking Baumkuchen?]

Aoki Matsu also understood what Maori Ran and the others said.

If Mr. Yulang had gone to the toilet and washed his hands before entering the living room, even if there was poison powder on his hands, it would have been washed off by water and wiped off with a handkerchief, and he would not have died from poisoning.

In other words, the poison on the door handle of Mr. Yulang's room might be a deception, and the murderer took double insurance. He used another method to make Mr. Yulang eat the poisoned annual ring cake.

In this case, the murderer has to choose one of the two!

Satake Yoshimi and Yonehara Sakurako, only these two people had the chance to poison the two cakes on the tray.

Judging from the entire case, Satake Yoshimi is obviously more suspicious.

Suspicion of Satake Yoshimi +2!

At this time, Mao Lilan's stomach suddenly growled.

Mao Lilan suddenly felt embarrassed: "I'm really sorry at this time. I'm a little hungry."

Yuanshan Heye said sympathetically: "That's right, speaking of Baumkuchen, I suddenly want to eat kamaboko."

"Why do you want to eat fish cake?" Mao Lilan asked curiously.

Yuanshan Heye said subconsciously: "Because the shapes are very similar, both are round and curved."

"Huh?!" Nanatsuki Koshimizu was stunned when she heard that, then she said thoughtfully, "An tit-for-tat?"

After hearing this, Aoki Matsu glanced at Nanatsuki Koshimizu, and then instructed Aihara Yoji who was standing beside him, "Aihara, go notify the criminal forensics department and ask them to determine the area of ​​the poison powder on Mr. Ikuro's door handle, and also conduct a drug test on the handkerchief that Mr. Ikuro was carrying."

"Yes!" replied Aihara Yoji.

Then Aoki Matsu said to Koshimizu Nanatsuki, "Let's go to the study."

"Yes!" replied Nanatsuki Koshimizu.

Soon the three of them arrived at the study.

Aoki Matsu sat in the place where Wakamatsu Serika had sat just now to check the computer. Koshimizu Nanatsuki and Maruta Ayumi stood on Aoki Matsu's left and right.

"Oh, Mrs. Wakamatsu saw the design of these words before she passed away!" Nanatsuki Koshimizu looked curiously at the word design of 'Wakato's Sake' in large and small fonts of different colors on the computer.

Aoki Matsu replied, "Yes, there seem to be 50 patterns in total. It seems that I have to select the appropriate ones from them with Mr. Shiina and others, and you all know what happened next.

When reading these words, Mrs. Wakamatsu held her eyes and looked very uncomfortable, so Mr. Fujinami gave her eye drops, and then I asked for help in recreating the crime scene. And just now, I found that Mrs. Wakamatsu took a pen and drew a horizontal line on the place where she was going to sign on the contract. It seemed that she suddenly stopped signing, or... "

"Or maybe she suddenly forgot how to write the word '若'." Koshimizu Nanatsuki continued.

Upon hearing this, Aoki Matsu looked at Koshimizu Nanatsuki and asked, "Koshimizu, have you figured out anything?"

"A tit-for-tat visual deception method." Nanatsuki Koshimizu answered, and then she told Aoki Matsu and Maruta Ayumi her reasoning, and then said with some embarrassment: "The key is evidence and motive."

The modus operandi was cracked, but it cannot be used as evidence to convict someone.

Moreover, he said that the other party admired President Wakamatsu, so he killed Ikuro Wakamatsu and Serika Wakamatsu to avenge President Wakamatsu. There must be such a person in reality, but legally speaking, this is not evidence. If the other party refuses to admit it, there is no way to convict him.
