Conan: Live in the Maori Detective Agency at the beginning

"After you buy drinks for everyone, you can mix the poisonous ice cubes into them by pretending to add creamer and syrup at the counter of the drink stand." Kudo Shinichi continued his reasoning.

"Wait a moment, Mai didn't add creamer or syrup herself." Noda Luomei questioned.

"Yes, we also found that there was no creamer and syrup in Urata's pocket." Mitani Yota agreed.

Both of them expressed reservations about Hong Shang Mai's suspicion.

"That's because she added the poisoned ice cubes and then realized that the drink was actually cola." Kudo Shinichi explained, "If she had added those, Mr. Urata might not have drunk it at all."

"She brought the drinks to you right before the show started because she didn't want them to be returned."

“So even if you find that the contents are not right, it takes a lot of effort to go back and forth to change the drinks once the lights in the gym go down.”

"But how did he carry this poisonous ice with him and walk around?" asked Officer Megure.

"Actually, I found this in the trash can in the restroom while Officer Takagi was out investigating." Kudo Shinichi took out a wallet from his pocket and continued, "This is a plastic wallet with a metal closure."

"Take it for identification." Officer Megure looked at Kuroba and said.

"Yes." Officer Hei Yu stepped forward and took

"As long as you put the ice cubes mixed with poison and a small piece of dry ice in this wallet, the ice cubes can be kept from melting for a long time." "As for Ms. Hong Shang, after you handed the drink mixed with poison to Mr. Mitani along with the other drinks, you went to the bathroom."

"First flush the dry ice down the toilet, then throw the wallet in the trash."

"Miss Hong Shang, I am right, right?"

"Kudo Shinichi is indeed worthy of his reputation." Hong Shang Mai closed her eyes and chuckled.

"You do look a bit like a famous detective, but you didn't forget that Dr. Urata and I both ordered iced coffee. And I gave both cups of coffee to Mitani to share with everyone," she continued.

"I didn't know he would give that cup of iced coffee to Dr. Urata, so how could he have poisoned it?"

"By the way, if I bet on a 50% chance of success or failure, then Ayako has a good chance too." Hongjo Mai looked at Ayako Ninagawa and said.

"No, the probability is 100%." ​​Kudo Shinichi retorted: "This is because you added poisoned ice cubes to both cups of iced coffee."

"How is that possible?" It was the first time that Inspector Megure heard of a criminal being so bold.

Isn't she afraid of poisoning herself?

Officer Megure asked quickly, "She obviously finished the contents of her drink."

"As long as you drink the drink quickly before the ice melts, you'll be fine."

"Even if that's the case, the poison will react in the cup after the ice cubes melt." Inspector Megure asked, "If you want to avoid drinking poison, throwing the ice cubes away will arouse suspicion from the audience around you."

Kudo Shinichi said: "If she is like Mr. Kamata, after drinking, she pretends to bite the ice cube and then holds the poisoned ice cube in her mouth."

"What!" Inspector Megure was even bolder than he had expected when he heard this.

Xingchen touched his chin and thought in surprise, what a cruel person! If there was any problem with the ice, both of us would fall here.

"Wait until the plan is made, then spit the ice into your palm."

"Then just hide it somewhere secretly."

"And that's it." Kudo Shinichi took out a ten-yuan coin and threw it into the sky.

Then it turned into a graceful arc and fell into the hood of the dress that was pulled open by Hattori Heiji behind Mai Hongue.

"It is certainly dangerous to hold a poisoned ice cube in your mouth. But there is no danger as long as you make sure that the poison has not melted in the middle of the ice cube. Besides, for safety reasons, we used old ice, right?" Kudo Shinichi said after deducing the facts.

"Did she really put it in the hood?"

"That's absolutely right." Hattori Heiji used a handkerchief to take out the ten-yuan coin from her hood and said, "Otherwise, come and see for yourself."

"This ten-yuan coin will still sparkle when you take it out, right?"

"This is the best evidence of the redox phenomenon that occurs after exposure to cyanide."

"So...so that's how it is." Inspector Megure said embarrassedly.

Officer Megure thought for a moment and asked, "But how did you know she hid the ice cubes in her hood?"

"Oh, that's because..." Kudo Shinichi was about to explain.

Hong Shang Mai began to speak.

"Because it's raining outside. It was clearly raining outside when we took Officer Takagi to look for Dr. Urata's car." Hong Shang Mai finally accepted her fate and explained with a complicated look in her eyes: "I didn't pull up my jumper hood, so you started to doubt me."

"Yes, it was at that time that I began to suspect that you were not wearing a hooded coat in order to avoid the ingestion of potassium cyanide through the skin after it melted in water." Kudo Shinichi nodded in response.

"So...Mai, it was really you who killed Urata." asked Mitani Yota.

"Yes, that's right. It was indeed me who poisoned and killed him." After admitting it, Hong Shang Mai began her explanation, "His behavior does not qualify him as a doctor at all."

"Why would you say that about him?" Noda Luomei asked in disbelief, "What on earth happened?"

"You should also know that he originally planned to publish a paper at the conference." Hong Shang Mai's words were a little angry, "But there was a case that was enough to overturn his theory, and this patient was living in our hospital at the time."

"I didn't expect that the patient's condition would suddenly worsen and he died just like that." There was some sadness in her voice, "It was as if that exception had never existed in this world."

"Could it be that Dr. Urata..." Noda Romi thought of a possibility.

"Yes, it was Dr. Urata who prescribed the wrong medicine for the patient, which caused the patient's condition to deteriorate rapidly." Hong Shang Mai said with some determination: "It was to protect his rotten theory that could not be broken."

Xingchen fell silent. This was a typical incident that could quickly deteriorate the doctor-patient relationship. Medical ethics is always the most important.

But someone did stand up and put an end to this incident, but she did not make a rational choice or this was the only choice she had.

"Actually, Dr. Urata told me this thanks to Ayako, because she refused to marry him last week." Hong Shang Mai explained, "When I went out with him to drink to relieve my boredom."

"At the time, I don't know whether he said it out loud because he felt regretful or because he was in so much pain."

"He said that he, who had the power to decide life and death, could be played around by a girl who was ten years younger than him. This world is really about karma."

After that day, she also designed a survey on human nature to see if he really regretted it.

The fact is, he didn't regret it. That's why Hong Shang Mai wanted to kill him.

As for the medicine bottles in the glove box of the car, she also put them there.

"You are really lucky, great detective, thanks to the rain." Hong Shang Mai said lightly: "Otherwise you would not be able to find evidence to prove that I am the murderer."
