Tuesday, August 19, less than 7:30 pm, Feitian Financial Company. "Talk*Follow*

When the forensic officer inspected the office computer, he found that one of the computers was not closed, so he asked Naoshi Nanzawa, Takako Fujii and Hiroshi Iino, "Can we turn it off directly?"

Hiro Iino said, "Ah, no, I will turn it off myself."

Takako Fujii took a cigarette and said, "Don't touch you guys. If you don't know which button you press, someone will be finished if the information comes out last time."

Nanze Shangshan asked, "Isn't it just that you used fake accounts to steal public funds, right?"

"Thieves?" Maori asked, "Can you kill him because your president knew about this?"

"I don't have it, I'm not like this." Hiroshi Iino said quickly, and then said, "If, if, if you want to kill the president, Mr. Nanze will have a share."

Nanze Shangshan shouted: "What did you say? I have no intention of killing the president."

"Didn't you have a customer who borrowed a lot of money and ran away? When the president turned around and asked you for the money, you still begged the president to take the money, but the president did not agree to you." Fujii Takako said, "Now that the president is dead, you should be relieved."

Nanze Shangshan said, "What about you? You often keep the president behind your back and say that the bad guys are the best to die early. You can't deny this."

"Yes," said Takako Fujii, "but I did not steal public funds nor owe money."

At this time, Yamazaki came over, greeted Maori, and asked Ran to find out the situation.

About thirty minutes later, the forensic personnel reported: "There was no toxic reaction found in the police department, office, kitchen, and all places in the bathroom. Mr. Nanze, Miss Filial Piety, and Mr. Iino's personal belongings either. However, we found a bottle of detergent that can neutralize cyanide compounds in the bathroom, and found detergent residues on the kitchen stove."

"What!" Meguri police department and Maori were shocked, and Meguri asked, "Are you saying someone wiped off the cyanide?"

"This is not clear yet," said the forensic.

Maori asked, "So where are they?"

"There are detergent residues on almost the entire stove," the forensic staff said.

"That was when I wiped the stove in the afternoon." Takako Fujii vomited a smoke ring, "Maybe it didn't wipe it clean."

"What about other places?" asked the Meguro Police Department.

The forensic staff said: "There are also detergent residues on the kitchen kettle, the bathroom door handle, the toilet table and the faucet, the toilet water storage tank and the mat, and the handkerchief of the filial son."

"Ah, I understand." Maori said, "This is the thing, Meguro Police Department."

"You said." said Meguro Police Department.

"The murderer who killed Mr. Hirata was Miss Takashi. She burned a pot of water on the stove before getting off work. When Mr. Hirata was counting money in the president's office, he heard the kettle making a whistle because the water boiled, so he hurriedly went to turn off the fire." Maori said, "At this time, the poison was stuck in Mr. Hirata's hands."

Meguro Police Department asked: "What do you mean is the poison on the gas switch?"

Maori said: "Yes, after Miss Tsai came over, she went to the bathroom to pour the detergent on her handkerchief and then came to the kitchen to wipe off the poison on the gas switch."

"So there is detergent on the handkerchief." said Meguro Police Department, then asked, "Miss Filial Piety, what are your explanations for this?"

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

"This," asked the Meguri Police Department, "Maori."

"You wiped the kitchen stove and kettle before you get off work. After you get it, you only wiped the gas switch. You wiped the bathroom after you." Maori said, "That's why you'll go to the bathroom again."

"Hmph!" Fujii Takako snorted coldly, pointed at Nanze Shangshan and Iino Hiroshi and asked the forensic staff, "Hey, are there any fingerprints for the two of them in the bathroom?"

"Some." said the foreman.

"Do you understand now? A confused detective." Fujii Takako said.

Maori said: "That bathroom was wiped when you first went there."

Meguri 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 on his neck and lost consciousness.

Conan, who had prepared the chair early, asked Maori to sit on the chair, and then said in Maori's voice: "These places were wiped by Miss Fuji before she got off work. She used detergent to wipe the stove and kettle to cover the gas switch later. The only place she wiped after Miss Fuji came in was the gas switch that was left with poison. The detergent was used to wipe the bathroom just in case. In this way, if the poison on Mr. Fujita's hand touched the objects in the bathroom, it could also be neutralized to avoid poisoning from others. This is the kind side of Miss Fuji."

"So that's how it is." asked the police department of Memu. "Miss Filial son, what else do you have to say?"

"If cleaning in the company is also a crime, then you can arrest me and go back." said Miss Filial Piety.

"Brother Maori?" asked the police department of Meguri.

Conan said in Maori's voice: "In the secret room of the president's office, the internal department of the president's office holds the hand, the door lock and the fingerprint of the right thumb left on a few paper money. That is to say, Mr. Hirata once went out of the president's office, touched the poison and locked the door. Then he died of poison when counting the money because of the bad habit of licking the right thumb when counting the money."

"There are no other items in the president's office that carry poison, so Mr. Feitian did not take things from outside through the window and return to the president's office. After disassembling them, he came into contact with the poison and then went to the president's office to close the door."

Meguro Police Department asked: "What if Mr. Hirata returns the things he brought back to the president's office through the window?"

Conan said in Maori's voice: "The windows in this room are closed from the inside of the room, and no poisons are found on it. In other words, Mr. Hirata did not contact the poison outside through the window and then close the window. If he contacted the poisonous items and returned the poisonous items, then when closing the window, he would leave fingerprints with poisons on the window."

Meguro Police Department said: "So that's it."

Conan said in Maori's voice: "So, this poison is in this room. The door of this room is equipped with a camera. The video recorded shows that after Miss Takashi, Mr. Nanze and Mr. Iino left, no one came in through the door until Mr. Hitan died of poisoning. So the poison in this room can only be left by Miss Takashi, Mr. Nanze and Mr. Iino. You three are the suspects who killed Mr. Hitan, 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 had not been poisoned at that time. After that, he left the president's office for something, and in this room he touched the poison with his right thumb."

"Mr. Nanze left a mobile phone number. If he called, Mr. Hirota would come to answer it, but there were no toxins found on Mr. Nanze's mobile phone number, and there were no traces of rubbing, so the murderer was not Mr. Nanze. Mr. Iino didn't leave anything, but he might know that Mr. Hirota would use his computer, but no toxins found on Mr. Iino's computer, and there were no traces of rubbing, so the murderer was not Mr. Iino."

"After the three suspects removed two of the suspects, the rest must be the prisoner."

"Miss Filial Piety, before you got off work, you burned a pot of water on the stove and poisoned it on the left side of the gas switch, so when Mr. Feitian heard the water ringing and turned off the fire, his right thumb touched the poison. Ms. Filial Piety, you are the only one who has entered the kitchen and close to the gas switch, and only your handkerchief has detergent residue. I think you originally planned to wipe the poison off when you go to work tomorrow, but the body was discovered earlier than you expected. Although the police have not found the poison left on the gas switch, it is a matter of time sooner or later, so you go to the bathroom to pour the detergent on the handkerchief, and then go to the kitchen to wipe the poison off the gas switch with the handkerchief. As long as you conduct in-depth inspection of the handkerchief and the gas switch, you will definitely find traces of cyanide that have existed."

"And, Miss Filial Piet, I see when you take out the cigarette box, when using a lighter, when you hold the bag and get things, you use your right hand. The only thing you really use your left hand is to turn the gas switch once. You keep putting your left hand in your pocket. I think it's because you're afraid that your left hand may get poisonous and you accidentally touch something else after you accidentally touch your cigarette. And when you smoke, your fingers often touch your lips. You're afraid that poison will touch your lips, so you use your left hand to rotate the gas switch and keep it in your pocket."

The police department of Meguru said: "Miss Filial son, please take out your left hand and let us check it."

"No problem." Fujii Takako said.

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

Conan said in Maori's voice: "It seems you have washed it off on the second time you went to the bathroom."

Takako Fujii said, "I'm still saying that, if you think it's a crime to clean with detergent, then arrest me."

"Okay," said Memu Police Department, "Miss Takako Fujii, please follow me to the Police Department."

Takako Fujii smiled and said, "This is absolutely fine. Anyway, the boss is dead and I am unemployed. The police department should be in charge of food."

Not long after, Memu Police Department left the guards and led the team away. Yamazaki also returned to Medei Restaurant to continue construction. Lan and Conan waited for Maori to wake up and went for supper...

Night, Miyamoto's family.

Yamazaki told Miko Miyamoto about the murder in the secret room of Miko Hirata. "I think this matter should be done by Miss Takako Fujii, but I didn't feel the murderous aura after the murder in her. I think her motive should be for revenge, great revenge, so she revenges for life, so she let go after revenge and was relieved."

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

Yamazaki said, "Yes, mom."

Miko Miko thought for a while and said, "There is a problem with the reasoning, which is based on the assumption that Mr. Hirata only uses his right hand. Whether it is to take things, open windows, or close windows, they all use their right hand, but using their right hand does not mean that they will definitely use their right hand."

"Well," Yamazaki said after thinking, "It's not bad, so it's impossible for Mr. Hirata to touch the poison outside through the window and then use his left hand to close the window."

Miko Miko said: "And that reasoning also ignored an item. Tip: The items that wipe things are not just handkerchiefs."

"Yeah," Yamazaki thought about it and said with a wry smile, "I can't think of it."

"Ha, heh." Meidaizi laughed.

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

"Uh, this has nothing to do with me." Meidaiko smiled, "I don't want to."

"Just guess riddles." Miko Miyamoto smiled, "And reminder, this kind of item that is used by everyone every day."

"It's not a tissue, right?" Meidaizi asked.

"It should be toilet paper." Yamazaki said, "Ms. Takako Fujii may use hydrolyzable toilet paper. She prepared toilet paper with detergent before entering the door. After wiping the gas switch, she went to the bathroom to process the toilet paper. So Ms. Takako Fujii was so calm because even if she was thoroughly inspected on the handkerchief, she could not find traces of cyanide. By the way, she had another intention to use detergent to wipe things, which was to pour a large amount of detergent into the toilet and sewer pipes, so that the traces of cyanide had not been detected."

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

"I understand." Yamazaki said, "because the toilet paper that had been rubbed with cyanide has completely disappeared."

"Okay, the time is almost over, I'm going back." Miyamoto Miko said, "Mideko, don't be too late."
