"I... I just used the computer for a while, and there was a policeman nearby who said it's ok..."

"You are all suspects. How can you run around the scene?"?! Give me some peace, will you

It seems that Mu Mu is really angry. Uncle Maori is not much better because she is gnashing her teeth after she is spit out a cigarette by the female staff with bad personality. If it is not for Xiao Lan, she will almost hit the female staff.

Gao Cheng was not affected by his emotions, and calmly observed the three suspects.

Let go of the entrustment. He still has to try his best to solve the case now. Otherwise, with Conan's ability, he may not have the chance to appear soon.

The number of cases he encountered is still much less than that of Uncle Maori. After all, he can't always be with uncle and Conan. The reason why he is as famous as uncle now is that he can solve the case first when Maori is present. Rao is so. The outside world also thinks that he cooperates with uncle.

Fame doesn't come easily, but you can't be suppressed by uncle like this

Gao Cheng gathers his mind and follows Mu Mu to investigate the three suspects.

The murderer is an ordinary person no matter what. Just like Miss Ishikawa before, it can't be regarded as nothing happened. There must be something different from ordinary people in behavior and thinking.

However, these three people are very suspicious. For the time being, I can't see why

"What? No poison was detected anywhere in the office? Is there a bathroom and a tea room? "

"Yes, officer, we have examined all the places where the victim might have touched..."

At the end of the investigation, the forensic officers also checked the scene, together with the personal belongings of several suspects, and no toxic reaction was found.

Gao Cheng's eyes are slightly fixed. His eyes sweep past the staff and fall on the personal belongings that have been checked.

There are more or less three criminal motives. President Feitian, who misappropriates public funds by hinohong, is aware of the crime, and Nanze is required by President Feitian to repay half of the money because of the high loan customers running away. In the end, Takako Fujii often says that President Feitian, a villain, died early and had a long life.

But the crucial source of poison can't be found

All three of them have been to the restroom, but the time is so short that even if the poison is disposed of, there is no trace.

Among the three people's belongings, Mr. Nanze's wallet, watch, home key, Notepad, ticket holder and a wet handkerchief.

Fujii has keys, watches, wallets, necklaces, cigarettes, lighters and an equally wet handkerchief.

The last one is Hino Hiro, including wallet, watch, car key, home key, paper towel and a wet handkerchief

Gao Cheng put his finger in his pocket and walked into the bathroom. The clues one by one went into the one minute mode in his mind.

With every move of the three suspects and all the details of Feitian financial company surrounded by Gao Cheng, the world quiets down and there is only one screen of thinking space.

Gao Cheng stands in the bathroom, and the number of light screens in front of him drops sharply. Finally, he decides on the female employee, Takako Fujii.

They all behaved suspiciously, but only Tadao Fujii was a little unnatural. Even if he kept smoking during the interrogation, it could be said that he was addicted to smoking, but he kept his left hand in his pocket and didn't take it out. Whether he took a cigarette or lit it, he used his right hand to solve it.

In addition, Nanze has touched a mobile phone, Fano has touched a computer, and Takako Fujii has touched a gas stove. If one is most likely to be poisoned, it is undoubtedly the switch knob on the gas stove.

What's interesting is that after Mu Mu scolded, Fujii used his left hand to turn off the gas stove switch, which was originally designed to facilitate the use of his right hand.

The whole scene of the crime reappeared in Gao Cheng's mind. From the time President Feitian ran out of the president's room in a panic when he received a call from the mahjong hall, the most likely place to go is the tea room.

The reason should be the whistle of water boiling. When Fujii left, he didn't turn off the gas stove. When the water was boiling, President Feitian rushed to the tea room to turn off the switch.

According to several toxic reactions at the scene, the left side of the switch touched by President Feitian's right thumb should have been coated with potassium cyanide in advance.

President Feitian, whose fingers were stained with poison, went back to the president's room, locked the door, started counting money again, and habitually licked his poisonous thumb

All the clues can be matched, and it makes sense that Fujii will go to the tea room.

The only problem is, how can the toxic reaction not be detected on the gas stove switch.

Gao Cheng opens a cupboard in the bathroom and looks for it carefully. Before he can find anything, Conan suddenly jumps out of the cupboard, steps on the toilet water tank and takes out a bottle of bleach with a handkerchief.

"Well?"

Gao chengleng looks at Conan with a serious face. If he looks back, he finds Xiaolan standing behind him awkwardly.

"Conan, you'll be scolded for rummaging!" Xiaolanwei looks at Conan with a red face.

"This is it!" Conan didn't pay attention to Xiaolan. He took the obvious bleach and showed a confident smile on his face.

Gao Cheng checks the bleach and doesn't react until Conan puts it back, jumps out of the water tank like a monkey and runs out of the bathroom. This boy is trying to grab food! After going out of the bathroom, Conan, who is very efficient, has already shot Maori Kogoro with a shot, which makes Gao Cheng cool behind him. In the past bandage freak incident, he was almost anaesthetized by Conan. It's really a bit dangerous to think about it. He doesn't want to be like Uncle Maori. Even if Conan helps reasoning for free, he can't“ Dad Xiaolan walked out of the bathroom and saw Uncle Maori fainting in the corridor. She wanted to help him“ I'm fine, LAN, "Conan said in a timely voice using uncle Maori," go back and get the iodine in our medicine box! " Xiaolan was surprised: "are you hurt?"“ No, I just want to know who the killer is and I need iodine! "“ I see. I'm going to get it now! " Xiaolan left Feitian finance in a hurry and went back to Maori detective office, where Gao Cheng's eyes were drawn. There's no way to stop Conan's reasoning, but he can't do nothing. At least it has something to do with his reputation. And God knows how Uncle Maori will be proud in front of him afterwards... Seeing Conan's little body supporting uncle, Gao Cheng can't see it. He shakes his head and helps uncle to sit down in the president's room“ Are you going to reason like this again? I said you're really in a mess, "Gao Cheng wondered, looking at Conan." it's always like this. How can you not be found out? Uncle, don't you feel it at all? "“ So I've almost been found a few times, "Conan thought seriously and said with a smile when he looked at Uncle Maori," but uncle, there's no problem. " Gao Cheng doesn't think much. He turns to Mu Mu and others who are still outside for further investigation“ When Xiao Lan brings iodine, I'm afraid those people are going to leave. Start reasoning. Now the gas stove has been turned on by you... "" you really know who the killer is, Chenghu. " Conan looked as expected“ If you don't know the killer, isn't it incompetent? However... "Gao Cheng looks at the three suspects who are eager to leave outside, and finally falls on Fujii:" if you can, talk to her alone first. " Although Fujii's behavior is rude and his character looks bad, he feels a touch of sadness at the bottom of his eyes. It would be heartless to expose him in public“ Why Conan was puzzled. What Gao Cheng thinks in his mind is that he met little Ishikawa Chihiro last time, Asai Ishikawa a long time ago and other prisoners like friends: "it's right for us to be detectives to find out the truth, but the mood of some prisoners still needs to be considered."“ Chenghu... "
