Corpse collector in Conan

The reliable detective did not live up to his expectations: "It is actually very simple to make the deceased drink a poisonous drink - just put a poisonous ice cube in each of the two drinks, so that the deceased picks a poisonous drink. The probability of a drink is 100%.”

"That's it!" The Memu Police Department made a clear voice, but soon, he felt that something was wrong.

After hesitating for a moment, the police officer approached Jiang Xia and whispered to him, "But I remember that the clerk lady drank all her drinks, and there was no trace of poison residue in her cup..."

Jiang Xia: "The murderer only needs to drink up her Coca-Cola in a big gulp before the ice cubes melt. Then she only needs to pretend that she also likes chewing ice cubes, and then she can open the lid of the cup without any violation and take out the unmelted Coca-Cola. Pour ice cubes into your mouth.

"This behavior, which many people would do, would not arouse suspicion. Then she could pretend to cough, spit out the ice cubes into her palms very naturally, and then hide the ice cubes elsewhere."

"Hide somewhere else?" The Memu Police Department felt bad when they heard this, "It's not too cold today. After such a long time, the ice must have melted. If so..."

Jiang Xia shook her head and reached into her wallet to rummage around.

After a moment, he paused slightly and raised his head to look at Hattori Heiji.

Hattori Heiji:"……?"

Jiang Xia pointed to his wallet: "You should have some rusty coins, take them out and try them."

Hattori Heiji looked suspicious: "Why don't you try?"

Jiang Xia glanced at his shiny change: "My coins are all smooth, and the ones with rust have been used long ago."

Hattori Heiji:"……"

Damn it, he was a famous detective in Kansai, but now he has become the assistant of a Tokyo detective.

However, thinking of Kudo Shinichi who was in a strange situation and the members of the organization who were eyeing him, the black-skinned detective realized that now was not the time for internal fighting. He reached into his pocket grumblingly, trying to find if there was anything Jiang Xia wanted.

At this time, a person next to him said: "I have it."

Akai Shuichi expressed his friendliness at the right time. He took out a slightly rusty coin and handed it over.

"!" Hattori Heiji remembered what Conan said about "the black organization seems to be very interested in Jiang Xia", and he suddenly became alert. He moved between the two of them, grabbed the coin, and prevented Akai Shuichi from selling the favor, " Give it to me, thank you for your hard work.”

Then he turned around, flicked his gloved fingers, and dropped the coin into the hood behind the female clerk.

Female clerk: "?!"

Before she came to her senses, Hattori Heiji pulled up her hat again and took out the coin.

Different from the slightly dirty appearance just now, the coin now looks shiny and brand new.

"Look." Hattori Heiji held the coin and showed it to the police. "After the ice cube melted in her hood, it dissolved into one with the cyanide inside. This water mixed with hydride caused the coin to undergo an oxidation-reduction reaction— —If you check her hood, you will definitely find enough cyanide to kill you."

"He actually hid it in his hood." The Megure Police Department really didn't expect the murderer to be so skilled and bold this time...but! The detective brothers are obviously better.

He happily asked: "How do you know she hid the ice cubes in that kind of place?"

Jiang Xia looked at the murderer: "Your seat is right at the outermost edge of the auditorium, very close to the drink stall. And because Miss Ninagawa is very concerned about her ex-fiancé, I think she will look towards you frequently.

"If you throw the ice cubes on the ground at this time, it will be easily seen by her, so you have to use yawning, adjusting your collar and other actions to hide your behavior of hiding the ice cubes.

"In addition, it is raining lightly outside. In this case, many people will choose to pull up their hoods when going out. But when you went out to help Officer Takagi identify the location of the deceased's vehicle, you walked out directly."

"So that's it." The female clerk sighed and smiled bitterly, "Yes, it is..."

"Who said that if cyanide is detected in the hood, it means you are the murderer?" Suddenly, a voice floated from the side, interrupting her confession.

Everyone was startled and looked around, and then they were surprised to find that it was the taciturn painter who spoke.

The painter looked at the female clerk, then at Shuichi Akai, and suddenly smiled sadly.

He imitated Jiang Xia's tone and said: "Some people like to get wet in the rain, and even if there is a hood on their clothes, they won't use it to cover themselves, so it makes sense not to wear a hood on rainy days.

"So there is a possibility - there is no potassium cyanide in her hood at all, just some rainwater that fell when she went out. And the reason why the coin can have a redox reaction is because there is a person in it. One side was coated with a generous amount of cyanide.

"There was cyanide on one side of the coin, but the other side remained rusty. After it entered the hood, the cyanide on it quickly dissolved in the rainwater, removing the rust on the other side, and it looked like It's like there was poison in the hood - someone wanted to use this method to blame the woman for the murder. "

Next to her, the short-haired female clerk did not expect this kind of unfolding. She was stunned for a moment, and her weak knees suddenly gained strength and supported her body again.

Police Department Mu Mu couldn't help but touch his chin: "..." What's going on? It actually sounds very reasonable.

Jiang Xia: "..." Unexpectedly, this talented painter is quite vindictive. This is obviously because he resents Akai Shuichi for using his precious painting book as physical evidence to the police... But it is a pity that there are still too many loopholes and it is not enough. Send someone from the FBI to talk to the police.

Sure enough, Akai Shuichi blocked this road with one sentence: "I haven't touched their drink cups."

"..."

Since the painter last met Jiang Xia, he has made up for this famous detective's resume. He knew in his heart that this man's reasoning was probably not wrong, but he still muttered with the simple intention of adding trouble to the tall man:

"Who knows if you wiped off your fingerprints in the dark - you and the deceased were seated right next to each other, and the coffee was placed very close to each other. Even if you made any small movements, it would be difficult for others to notice."

Akai Shuichi glanced at this Uzo minion and felt the undisguised malice coming from him.

Akai Shuichi: "..." Although he did not kill anyone and had a clear conscience, he did not want to dwell on this topic anymore - to be honest, the recent frequent accidents made him afraid to be careless, so before coming, he covered it with special paint I don't want to leave my fingerprints anywhere.

Therefore, if the police follow the point of "whether there are his fingerprints on the drink cup", then they may immediately discover something unusual about him...
