"What, do you want us to investigate the slippers?"

"What the hell are you doing?"

“We are investigating the case.”

In the living room, Officer Meguru looked at Hattori Heiji speechlessly. Even Kogoro Mouri felt outrageous-Is there anything to do with the heel of slippers poisoning?

"Don't be so ignorant, this is a very important thing." Hattori Heiji said with a smile: "Of course, the police officer's slippers must be checked, and there are also a few people queuing outside the room."

Conan raised the plastic bag in his hand, "Please put the slippers you are wearing now into the bag with the name written on it."

After getting everyone's slippers, two detectives, one big and one small, quietly retreated and handed the slippers to the police officers in the forensics class.

After obtaining the test results, Chen Xing followed them to the study where Ruosong Qinxiang was alone.

"Madam, are you still inside?" Hattori Heiji knocked on the door. "Your slippers are left without checking, because we did not detect any poison reactions on other people's slippers."

Conan added: "There will be poison powder on the slippers because when the poison powder is spread on the door handle of Mr. Yurang's room, it also sprinkles on the murderer's slippers."

Chen Xing heard from Tomo Amuro that the poison powder falling on the floor under the door handle is about 10 cm apart.

"So, just check your slippers and you can determine whether you are the murderer." Hattori Heiji said as he opened the door while he said.

But when he saw the situation in the study clearly, his face changed.

Chen Xing frowned. In the room, Ruosong Qinxiang pinched her throat with both hands and lay on the floor, her mouth wide open, her face was ferocious, and she had no sound.

"How could it be..." Conan couldn't believe it.

Soon, after the police officer at the door informed Officer Meguro, everyone rushed over.

"Is the cause of death still caused by cyanide poisoning?" Officer Memu squatted on the ground, looking at the people on the ground with a headache.

This is the second person killed tonight, and the one who was killed before has been killed has been killing people in succession.

"But, isn't this a suicide case?" Fujiha Junsheng said in confusion: "When we left this study, wasn't the person who closed the door the last one? The vice president was still alive at that time.

The body of the vice president was also found by the detective boy from Osaka. In the first place, the only possibility is to commit suicide, right?"

"Yes, if this is considered a murder case, it will become a murder in a secret room. It is an impossible criminal method, right?" said Osamu Satake.

"This may not be impossible." Conan walked behind the desk at some point and said, "Because there are many suspicious things on the table.

--The black tea brought to the wife by the female housekeeper, Ms. Yonahara, was only half drunk; the pen cover lent to the wife by Mr. Shiina, the general manager, was still behind the pen, and the tip of the pen was exposed; the contract letter signed and sealed by the wife by the secretary, Ms. Satake, was only half written; and the eye drops lent to the wife by the chief designer, Mr. Fujihara, also took out the box, as if it had been used."

Conan said: "All these things are suspicious, right?"

Hattori Heiji took over the conversation, "That is to say, as long as you skillfully use the things on this table, even if the murderer is not in this study, you may still poison Mrs. Wakamatsu. In addition, there is the thick Mandarin dictionary that fell beside her and the box containing the dictionary, which is also suspicious."

Officer Meguchi picked up the dictionary casually, "The page that the dictionary opens seems to be stuck in the part of the sound of wa."

"Overall, the reason for the poisoning is probably because the wife wanted to query a certain character at that time, right?" Kogoro Mouri casually guessed: "For example, she has a Chinese character that doesn't pronounce, so she wants to check dictionaries or something."

Officer Megu nodded and said, "So, the problem is that the contract letter entrusts the wife to sign and seal, as well as the instruction manual for use of eye drops."

"It may be that the murderer knew in advance that the words contained in difficult-to-understand Chinese characters or words, so he set up a trap and asked his wife to check the dictionary that had been smeared in advance." When Kogoro Maori said this, his eyes were already aiming at the few people standing at the door of the study.

Juno Fujihara hurriedly said, "Wait, I don't think the vice president will have Chinese characters that he doesn't know."

Satake Yoshio said, "Because the vice president once took the first level of Chinese character calibration. In addition, even if you really have to doubt us, please read the letter the vice president left to me in advance, okay?"

"letter?"

"It was the letter given to me by the vice president in advance. She said that if she had any words, I would remember to hand over the letter to the police."

Satake Yoshino's eyes were slightly lowered, "The letter was kept in the safe in this study room, and the content of the letter was the wife's confession.

When she heard that the president was assassinated at Karuizawa Villa and rushed to the bathroom, in fact, she saw her son covered in blood holding a knife, but she chose to protect her son. This was what she wrote in her hand."

While she was saying this, Officer Meguri also arranged for the police to open the safe and indeed saw the letter.

As for the reason why Ruomatsu Qianka protects her son, it was because her son already felt that the person who embezzled public funds was actually her, so he couldn't let him tell her about it.

She let her son, covered in blood, pounce on the president's body, hide the blood splashed on her body, and create evidence that the police mistakenly thought it was an outsider's crime. At the same time, she hid the murder weapon and later helped him deal with it. As for the pre-death message written by Ruomatsu Kohei, she also used trompei's technique to hide it.

But she was afraid that one day she would know that the real murderer would be killed by her son and hoped to use the pre-death message as evidence and hand it over to the police.

The above is the general content of Ruosong Qinxiang’s confession.

After reading it, Officer Megumi pondered: "Are you the only one who knows that there is this letter, as the secretary?"

"It should be." Satake Yoshio said calmly: "But since the vice president opens the safe every night to check if the content of the letter has been opened, someone may be suspicious of it."

At the end of the day, she seemed to look at the butler accidentally.

"I do feel like my wife is hiding something. Once when I came into this room to clean, my wife looked at me in front of the safe and said that I must knock on the door before entering the room in the future, and blamed me angrily."

Mihara Saki said: "But I think the other people should have noticed it too, because the wife often calls the company's people to this room to discuss the company's affairs together."

Officer Megu immediately looked over, feeling a little helpless, "In other words, you guys should all know that this letter exists, right?"

He thought the letter hidden in the safe was so hidden, but he didn't expect it to be known to everyone.
