Chapter 500-6 Hidasha's Reasoning

August 19th, Tuesday, before 7:30 p.m., Feitian Financial Club.

When the forensic personnel checked the computers in the office, they found that one computer was not turned off, so they asked Nanzawa Naozen, Fujii Takako and Iino Hiroshi, "Can we just turn it off?"

"Ah, no, I'll turn it off myself," Iino said.

Takako Fujii took a puff of a cigarette, and then said: "You guys, don't touch it randomly. If you can't figure out which key to press, if the information from last time comes out, someone will be finished."

Nanze Shangshan asked: "Could it be that you used a fake account to steal public funds?"

"Stealing?" Maori asked, "Could it be that you killed him because your president found out about it?"

"I didn't, I didn't do that." Iino Hiroshi said quickly, and then said, "If, if there is someone who wants to kill the president, Mr. Nanze is also involved."

Nanze Shangshan shouted: "What are you talking about, I have no motive to kill the president at all."

"Didn't you have a client who borrowed a lot of money and ran away? When the president asked you for the money in turn, you still cried and begged the president to eat the money, but the president didn't agree to you " Takako Fujii said, "Now that the president is dead, you should be relieved."

Nanze Shangshan said: "What about you? You often tell the president behind your back, saying that it would be best for that kind of villain to die early, you can't deny that, right?"

"That's right." Takako Fujii said, "But I neither stole public funds nor owed money."

At this time, Yamazaki came over, greeted Maori, and asked Lan about the situation.

About 30 minutes later, the forensic personnel reported: "The police department, no toxic reaction was found in the office, kitchen, and bathroom. No toxic reaction was found on the belongings of Mr. Nanze, Miss Xiaozi, and Mr. Iino. But we found a bottle of cyanide-neutralizing detergent in the bathroom and detergent residue on the kitchen stove.”

"What!" Police Department Megure and Mori were taken aback, and Police Department Megure asked, "You mean someone wiped off the cyanide?"

"It's not clear yet," said the forensic officer.

Maori asked, "So where are they?"

Forensic personnel said: "There are detergent residues on almost the entire stove."

"That's because I wiped the stove this afternoon." Takako Fujii blew out a smoke ring, "Maybe I didn't wipe it clean."

"What about other places?" Mumu Police Department asked.

The forensic officer said: "There are also residues of detergent on the kettle in the kitchen, on the doorknob in the bathroom, on the sink and faucet, on the toilet tank and mat, and on Miss Xiaozi's handkerchief."

"Ah, I see." Mori said, "That's how it happened, Megure Police Department."

"Tell me." Megure Police Department said.

"The murderer who killed Mr. Feitian was Miss Xiaozi. She boiled a pot of water on the stove before leaving work. When Mr. Feitian was counting the money in the president's office, he heard the sound of the kettle beeping because the water was boiling. Hurry to turn off the fire." Maori said, "At this moment, the poison is on Mr. Feitian's hands."

Meguro Police Department asked: "You mean the poison was put on the gas switch?"

Mao Li said: "Yes, after Miss Xiaozi came over, she went to the bathroom and poured detergent on the handkerchief, and then went to the kitchen to wipe off the poison on the gas switch.

"

"That's why there is detergent on the handkerchief." Megure Police Department said, and then asked, "Miss Xiaozi, what's your explanation for this?"

"The detergent on my handkerchief should be left when I wiped my hands." Takako Fujii asked, "Also, officer, do you think I have so much time to wipe these things?"

"This," Megure Police Department asked, "Maori."

"You cleaned the kitchen stove and kettle before leaving get off work. After you were found, you only cleaned the gas switch. You cleaned the bathroom afterward." Maori said, "That's why you went to the bathroom again."

"Hmph!" Takako Fujii snorted coldly, pointing to Nanzawa Naozen and Iino Hiroshi and asked the forensic personnel, "Hey, are there any fingerprints of them in the bathroom?"

"Yes." The forensic officer said.

"Do you understand now? Confused detective." Fujii Takako said.

Maori said, "The bathroom was wiped when you first went there."

The Mumu police department asked: "But, brother Maori, what's the point of doing this?"

"This..." Maori couldn't answer for a while, and then he felt a numbness in his neck and lost consciousness.

Conan, who had prepared the chair earlier, let Maori sit down on the chair, and then said in Maori's voice: "Miss Xiaozi wiped these places before she got off work. The purpose of wiping the stove and kettle with detergent is to wipe the gas switch later. As a cover, the only place Ms. Xiaozi wiped after she came in was the poisoned gas switch she left behind. The detergent was used to wipe the bathroom just in case, so that if the poison on Mr. Fatty's hands came into contact with Objects in the bathroom can also be neutralized to prevent other people from being poisoned, this is the kind side of Miss Xiaozi."

"So that's the case." Mumu police department asked, "Miss Xiaozi, what else do you have to say?"

"If it's a crime to clean up in the company, then you can take me back." Miss Xiaozi said.

"Brother Maori?" Mumu Police Department asked.

Conan said in a Maori voice: "In the secret room of the president's room, the fingerprints of the right thumb left on the door handle, door lock and several banknotes in the president's room have poisonous substances, that is to say, Mr. Hida once went out from the president's office, came back and locked the door after touching the poison, and then died of poisoning because of his bad habit of licking the thumb of his right hand while counting money."

"There are no other poisonous items in the president's room, so Mr. Feitian didn't take things from the outside through the window and return to the president's room. After disassembling, he touched the poison and then went to the president's room to close the door."

Megure Police Department asked: "What if Mr. Hida returned the things he took back to the president's office through the window?"

Conan said in a Maori voice: "The windows in this room are all closed from the inside of the room, and no poison was found on them, that is to say, Mr. Fei Tian didn't close the windows after being exposed to the poison outside through the windows." , if you touch something poisonous and then return it, you'll leave poisonous fingerprints on the window when you close the window."

The Mumu Police Department said: "So that's the case."

Conan said in a Maori voice: "So, the poison is in this room. The door of this room is equipped with a video camera. Before Mr. was poisoned and died, no one came in through the gate. So the poison in this room can only be left by one or several of you, Ms. Xiaozi, Mr. Nanze and Mr. Iino. The three of you are killing The suspect of Mr. Feitian, the only suspect in this secret room killing incident."

"We once called Mr. Feitian. At that time, Mr. Feitian was counting money in the president's office. That is to say, he hadn't been poisoned at that time. Then he left the president's office for some reason, and touched it with his right thumb in this room. poison."

"Mr. Nanze left a mobile phone. If he calls, Mr. Hida will come to answer it, but there is no toxin found on Mr. Nanze's mobile phone, and there is no trace of rubbing, so the murderer is not Mr. Nanze. Iino Mr. did not leave anything behind, but he may know that Mr. Hita will use his computer, but Mr. Iino's computer was not found toxin, and there is no trace of rubbing, so the murderer is not Mr. Iino."

"After the three suspects get rid of two suspects, then the rest must be criminals."

"Miss Xiaozi, you boiled a pot of water on the stove before leaving work, and put poison on the left side of the gas switch, so when Mr. Feitian heard the sound of water and turned off the fire, his right thumb came into contact with the poison. Miss Xiaozi, here Only you have been in the kitchen, near the gas switch, only your handkerchief has detergent residue on it. I think you planned to wipe the poison off at work tomorrow, but the body was found later than you expected It's early, although the police haven't found the poison left on the gas switch, but it will be a matter of time, so you go to the bathroom and pour the detergent on the handkerchief, and then go to the kitchen to wipe the poison on the gas switch with a handkerchief Lost. A thorough examination of the handkerchief and gas switch will surely reveal traces of the presence of cyanide."

"Besides, Miss Xiaozi, I see that you use your right hand when you take out the cigarette case, when you use the lighter, and when you take things out of your bag. The only time you really use your left hand is to turn the gas switch once. You always Put your left hand in your pocket, I think it is because you are afraid that your left hand may accidentally touch other things after being stained with poison. You seem to be addicted to cigarettes, and when you smoke, your fingers often touch your lips. It gets on your lips, so you use your left hand to turn the gas switch, and keep it in your pocket."

The Mumu Police Department said: "Miss Xiaozi, please take out your left hand for us to check."

"No problem." Takako Fujii said.

After a while, the forensic personnel reported that there was no poison on Fujii Takako's left hand, but there was detergent residue.

Conan said in a Maori voice, "Looks like you washed it off the second time you went to the bathroom."

Fujii Takako said: "I'll say the same thing, if you think cleaning with detergent is also a crime, then arrest me."

"Okay then," Megure Police Department said, "Miss Fujii Takako, please come with me to the Metropolitan Police Department."

Takako Fujii smiled and said, "That's perfectly fine. Anyway, the boss is dead, and I'm unemployed. The Metropolitan Police Department should be in charge."

Not long after, the Megure Police Department left the guards behind, and then led the team to leave. Yamazaki also returned to Mei Dai Restaurant to continue working, and Lan and Conan waited for Mouri to wake up and went to have dinner. ...

Night, the Miyamoto family.

Yamazaki told Miyamoto Miko about Hida Mitsuhiro's secret room murder, "I think this should be done by Ms. Fujii Takako, but I don't feel the murderous aura after the murder in her. I think her motive should be for Revenge, big revenge, big enough to take revenge as the revenge of life, so after taking revenge, let go and be free."

"So you can't be sure that she is the murderer, and you want to ask my opinion." Miko Miyamoto smiled.

Yamazaki said, "Yes, Mom."

Miko Miyamoto thought for a while and said: "There is a problem with the reasoning, which is based on the assumption that Mr. Hida only uses his right hand. Whether he is holding things, opening windows, or closing windows, he uses his right hand. , but being right-handed doesn’t mean you must be right-handed.”

"Well," Yamazaki thought for a while and said, "That's right, so it cannot be ruled out that Mr. Feitian may let his right thumb touch the poison outside through the window and then use his left hand to close the window."

Miyamoto Miko said: "And that reasoning also ignored an item. As a reminder, the item for wiping things is not just a handkerchief."

"Well," Yamazaki thought and thought, and smiled wryly, "I can't think of it."

"Heh, heh." Mei Daizi laughed.

"Oh, you thought of it?" Miko Miyamoto asked.

"Uh, it has nothing to do with me." Mei Daizi smiled, "I don't want to."

"Just think of it as a riddle." Miyamoto Miko said with a smile, "Reminder, this kind of wiping thing is basically used by everyone every day."

"Could it be a tissue?" Mei Daizi asked.

"It should be toilet paper." Yamazaki said, "Ms. Fujii Takako may be using hydrolyzable toilet paper. Before entering the door, I prepared toilet paper with detergent. After wiping the gas switch, I went to the bathroom to dispose of this toilet paper. So Fujii Miss Xiaozi is so calm, because even if the handkerchief was thoroughly inspected, there was no trace of cyanide. By the way, she used detergent to wipe things for another purpose, which was to wash a lot of water. Poured cyanide into toilets and sewers, so there was no way to detect traces of cyanide ever present."

"Yes, but this is just a guess, a guess without any real basis, although it may be the same as the truth." Miko Miyamoto said, and then asked, "Do you understand?"

"Understood." Yamazaki said, "Because the toilet paper that was wiped with cyanide has completely disappeared."

"Okay, it's almost time, I'm going back." Miyamoto Miko said, "Mei Daizi, don't be too late."

"Understood, mother." Mei Daizi smiled. ...
