After listening to the words of the Twilight Police Department, Officer Takagi left directly with a few people.

Outside the gymnasium, it was raining at some point, although they didn't bring an umbrella, but the group didn't care, but rushed directly into the rain.

Officer Takagi turned around and led the men away, and the Dusk Police Department turned to look at Yui, who wanted to know what the half-sentence that Yui hadn't finished just now was.

"What did you just want to say, did you find any evidence?" asked the Twilight Police Department.

But he saw Wei shook his head slightly, and said, "Evidence? No, in fact, this evidence needs to be sent by the police department to find it!"

"Huh?" the Dusk Police Department froze.

Maori Kogoro couldn't help but grin, "Yui, then why did you just say murder?

Wei smiled faintly and said softly: "But if I'm not mistaken, I already know the murder method." ”

"Know the modus operandi?" said the Twilight Police Department in amazement.

Yui nodded slightly.

Hattori Heiji also smiled and said, "Yes, this technique is simply simple! ”

"This ......," the Twilight Police Department blinked.

Wei smiled faintly and said, "Let's go look for it first! Find that thing, don't worry, that thing should be in the gymnasium." ”

"Okay. The Twilight Police Department nodded, and immediately turned around and told Officer Chiba to find the thing.

Hattori Heiji looked at the Twilight Police Department and told Officer Chiba to look for it, and leaned over again and said, "Concubine-kun, how sure are you that thing?"

I didn't look at Hattori Heiji, just looked at the rain curtain outside, suddenly smiled slightly, and said, "Na, who is the one who doesn't have an umbrella in the rain?"

"Huh?" Hattori was stunned.

Conan, who had not spoken beside him, suddenly shouted suddenly, "Sister Yui, you mean?"

Wei said lightly: "She can't throw that thing away, I've been thinking about it just now, where might she have put it......"

"I didn't expect it to be there!" Hattori Heiji understood, smiling triumphantly.

While waiting, Yuan Zi looked at the rain curtain outside with a puzzled face, and complained: "What a bad luck! First, there was a strange murder, and the play was stopped halfway, and now it is starting to rain without God giving face, and the atmosphere of celebration has been messed up!

"Garden!" Lan said angrily: "You still say, how can you change the plot inexplicably!

"Uh...... This ......" Yuan Zi hurriedly raised his hand and surrendered to Lan with a smile on his face, trying to dispel Lan's anger.

You know, it's not terrible for Lan to be angry, it's really terrible to be angry!

But if you really get angry, you won't mind causing some trouble to the garden.

And no matter how big or small this trouble is, she doesn't want to see it! So, let's put Lan's anger out first!

didn't care about Lan and Yuanzi muttering something over there, but at this time they were slightly drooping their eyelids and were silent.

Mourning watched not far away, a trace of doubt flashed in his eyes.

Is it a delusion? I always feel that Yui seems to be a little nervous!

It didn't take long for Officer Chiba to hurry back, holding a evidence bag in his hand, which contained a strange thing.

The Dusk Police Department glanced at it and said, "Weijun, this should be evidence, right?"

Yui glanced at it and nodded, and said, "Yes." ”

Mori Kogoro leaned over to take a look and said, "Yui, now that the evidence has been found, it is time to call those people and Takagi-kun back, right?"

Now that the evidence has been found and the method of murder is known, the case has been solved.

But he saw Yui shaking his head lightly and said, "No, I still need Officer Takagi to find something, if I'm not mistaken, Officer Takagi will definitely find that thing." ”

"That's right," Dusk Police nodded, knowing what Yui was referring to.

If everything is really as Yui said, then that thing really has to be found.

"Jingle bell~~~"

The Dusk Police Department's cell phone rang.

"Is that so? It's so hard for you!" "Twilight hung up his phone and looked up at Yui, who raised his eyebrows slightly, and was about to say something when he heard Officer Takagi's voice ringing.

The Twilight Police Department turned around, "Takagi-kun, how's the situation going?"

Officer Takagi approached with Yota Mitani, Maii Hirokami and Yumemi Noda, took out a small transparent bag with a small bottle in it, and said, "I found this thing on the dashboard of Mr. Kamata's car, and I was wondering if it could be potassium cyanide?"

The Twilight Police Department glanced at the thing, took it and said, "Thank you for your hard work," and as he spoke, the Twilight Police Department turned to look at Wei and said, "Weijun, I just received a call from the identification team, just like you said, there was no trace of poison added to those four cups. ”

"Well," Wei nodded, and said lightly, "In that case, then this case can be judged as a suicide case, right?

"Huh?" Yui's words startled Hirogami Mai, and said in amazement: "This young lady, I don't know what you're talking about? Just now, the police department has already said that no trace of poison has been detected in the cups of Mr. Kamata or the three of us, and Mr. Kamata has almost drunk all the drinks, and besides, he has also found a bottle of potassium cyanide, isn't it?

Wei glanced at Hongshang Maiyi lightly, the eyes were extremely flat, and the cold voice sounded in everyone's ears, "It does seem like this, it will indeed give people the illusion that Mr. Kamata committed suicide by taking poison, but as long as you use something, you can easily complete this murder!"

"Something?" Hirosami's face changed slightly.

"Yes," Yui continued in a flat tone, "this is the basic of criminal methods, as long as you use ice cubes. ”

"You say using ice?" Yota Mitani and the others were startled.

Wei didn't care about these people's eyes, just lowered his eyelids slightly, and said slowly: "The poison used by the murderer is potassium cyanide, which is extremely difficult to dissolve in the ice, as long as you dig a hole in the ice, inject potassium cyanide into the center of the ice cube, and then use a small piece of ice as a cover, and then put it in Mr. Kamata's drink cup with other ice cubes, you can let Mr. Kamata drink drink most of the drink before the poison dissolves out." ”

"But in that case, there should be dissolved poison left in his cup!" the Twilight Police Department wondered.

Just now, because Wei was too lazy to talk twice, he didn't explain the criminal modus operandi clearly, so although the Dusk Police Department knew that Yui had gone to find something, they didn't understand the criminal modus operandi.

"About this," Yui smiled faintly, and said, "I told the Twilight Police Department before, right? Mr. Kamata's drink lid is open, right? Do you know why?"

Mori Kogoro was also puzzled, and pondered, "Is it because he was in pain after drinking the poison, so he held the drink cup too tightly, etc...... Yui, what do you mean?" Kogoro Maori kind of understood.

The Twilight Police Department still didn't understand, and frowned, "Maori-kun, what do you understand?"

Maori Kogoro raised the corners of his lips and said proudly: "It's very simple, there is only one reason why the lid of a drink like this with ice cubes will be opened, and that is that the poison is not drunk by Mr. Kamata, but eaten!"

"Eat it?" the Dusk Police Department was stunned.

Next to him, Officer Takagi suddenly shouted, "So that's what happened! Police, don't you always put the rest of the ice cube in your mouth and squeak and bite?"

"I see," the Dusk Police Department understood, "as long as we know that Mr. Kamata has this little habit, I can indeed kill him with poison, and this toxin will not remain on the cup." ”

"Yes. Yui nodded lightly and continued: " It is impossible for Mr. Mitani and Miss Noda, who are only in charge of delivering the drink cups, and as for Miss Ninagawa, who sells drinks, she is likely to be the one who adds ice cubes, but she has changed the iced coffee that Mr. Kamata originally ordered for Coke, and no one will poison a drink that may be returned, and at that time, there was a person who ordered iced coffee like Mr. Kamata, so that the target of poisoning could not be determined, and the danger of placing success or failure on a bet with only a 50% probability was too high, so the only person who poisoned Mr. Kamata was you, who was responsible for buying a drink and then getting it to Miss Yukagami in the audience！”

Everyone also looked at Hongshang's dance clothes, whose faces became ugly.

Wei's words continued, and he said lightly: "After you buy drinks for everyone, as long as you pretend to add milk and sugar to it on the counter of the beverage stall, you can add ice cubes mixed with poison!"

"Wait!" At this time, Noda Yumemi exclaimed, "But she didn't add milk and sugar to her dance clothes!"

"That's right!" Yota Mitani said, "Didn't you find unused milk and candy in Dr. Kamata's pocket?"

"That's because after she added poison-mixed ice cubes, she found out that the drink inside was Coke!" Yui explained lightly: "If she added those, Dr. Kamata wouldn't have drunk it!"

Yota Mitani and Yumemi Noda opened their mouths, but they couldn't say anything.

Yui continued: "And Miss Hirogami brought the drink to you before the play started, in the hope that the drink would not be returned, even if it was found that the drink inside was wrong, but as long as the lights in the gymnasium dimmed, it would take a lot of effort to change the drink. ”
