A technical house in the world of detectives

Facing Conan’s puzzled face, He Yun did not speak, but just turned his head and went to the bathroom.

Conan hurried to follow.

Xiaolan saw this scene and did not stop it.

If it was before, she would still think that Conan was making trouble, but now, Xiaolan will help Conan hide his true identity.

“Really, if it weren’t for He Yun’s presence, Conan’s smelly imp would have made trouble on the scene again.”

Kogoro was also much more relaxed when he saw Conan walking around behind He Yun.

“Dad…”

Xiao Lan was a little helpless, after all, Xiao Goro himself still didn’t know that his fame was brought to him by Conan, and when He Yun solved the case, he would also push the credit to him.

The toilet here is like home, a sink, a toilet, and the wall above the toilet is made into a cabinet.

He Yun rummaged inside and found what he wanted.

“What’s that?”

Due to his height, Conan couldn’t see what He Yun had in his hand.

“Blanch.”

Saying that, He Yun put the bleach back in its place.

“Blanch? Could it be…”

Conan felt like he understood again.

“Xiaolan, can I trouble you to go home and bring the iodine wine.”

In addition to the bathroom, He Yun directly found Xiaolan.

The location is not far from the Māori Detective Agency, just a few minutes’ walk away.

“Iodine wine? Has anyone been hurt? ”

Xiaolan glanced at He Yun and Conan, but did not see any signs of injury.

“No, as long as there is iodine, you can know who the murderer is.”

“I understand, I’ll get it!”

Hearing He Yun say this, Xiaolan immediately took a long leg and ran towards the house.

And looking at a group of He Yun, who was still checking the toxic reaction of the entire room, it stopped them.

“No need.”

Officer Twilight was a little uncomfortable to understand why it was not necessary.

“Because the poison has been wiped off by the murderer.”

He Yun explained.

“What? You mean, the murderer once returned to the scene and wiped the poison off? ”

Maori Kogoro immediately jumped out to show his IQ.

“Yes, the murderer is one of the three.”

He Yun pointed to the three Feitian Financial employees and said.

“Hey, don’t talk nonsense.”

Takako Fujii was still holding a cigarette, with her left hand in her pocket, looking like a hanger.

“Of course the evidence is, it’s in you.”

He Yun was naturally sure that he would say such things.

“He Jun, why do you say that there is a murderer among the three of them?”

Officer Twilight did not ask about the evidence first, but wanted to know how He Yun judged.

“Because of habit.”

“Habit?”

“The deceased was poisoned because his right hand was poisoned, and if he was poisoned normally, he would generally choose food or the place where the victim would touch his mouth, so as to ensure that the crime was carried out, so why was the deceased’s poison stained on his own hands?”

He Yun did not directly explain it, but it was also hinted at clearly.

“You mean the murderer will lick his right thumb?”

Officer Twilight immediately understood what He Yun meant.

“That’s right, because the murderer knows the habits of the deceased, just like Mr. Minamizawa often bites his finger, and Miss Fujii has always held a cigarette with her right hand, it is a habit.”

“I understood, because the murderer knew the habits of the deceased, he smeared poison somewhere in the company, and when the deceased was counting cash, he touched the poison and licked his fingers, so he was guaranteed to be able to kill the deceased.”

Kogoro looked like he suddenly realized.

“That’s what it means, so the murderer must be an employee of Fata Finance, only in this way will he know when the deceased will count money, and lick his fingers when counting money.”

He Yun nodded.

“Even if this is the case, then what evidence do you have that the murderer is among us.”

Takako Fujii shook the cigarette in her hand and spilled the soot on the ground.

“Don’t spoil the scene, hey!”

Kogoro and Officer Twilight exploded again.

“It’s okay, she didn’t destroy the evidence.”

He Yun waved his hand.

“If you can, please take out the things on your body and take a look, you can prove your innocence.”

He Yun said so, and they couldn’t not cooperate.

“Let’s start with Mr. Minamizawa.”

Officer Twilight knew that it was time for him to appear.

“Hmm… Wallets, watches, keys to your home, notepads, ticket holders and handkerchiefs… Hey? A little wet handkerchief? ”

“I just went to the bathroom…”

“Next is Miss Fujii.”

“Home keys, watches, wallets, necklaces, cigarettes, lighters and handkerchiefs… Hey? Your handkerchief is also wet. ”

“Of course, I went to the bathroom too.”

“Then Mr. Iino.”

“Wallets, watches, car keys, home keys and paper, then handkerchiefs… Hey? Yours is almost soaked…”

“I, I sweat easily…”

“Well, check it out right away!”

Officer Twilight immediately wanted to call the inspectors over for testing.

“No need to call the tester, there is no toxic reaction on this.”

He Yun stopped him again.

“What! So how do you prove who the murderer is? ”

Officer Twilight and Kogoro exploded again.

“The victim was potassium cyanate poisoning, want to make potassium cyanate lose toxicity, you can use sodium sulfate, which is a bleach that doctors often use to remove the color of disinfectant, and in the bathroom cabinet, there is a bottle of bleach mixed with sodium sulfate in order to make it react at room temperature.”

“Go check it out.”

Hearing what He Yun said, Officer Twilight immediately asked a police officer to go over and collect evidence.

“Sodium sulfate is colorless and odorless, standing on a handkerchief looks like it is stained with water, which of you has sodium sulfate on your handkerchief, take the initiative to admit it, the crime will be lighter.”

He Yun did not look at the three of them, but at the three handkerchiefs on the table.

However, no one came out to admit that the murderer still seemed to have a fluke mentality.

“Cousin, iodine wine is here.”

At this time, Xiaolan also ran in from outside.

“Don’t admit it yet? Xiaolan, drop a drop of iodine wine on each of these three handkerchiefs, Conan…”

He Yun lowered his head and said a few words in Conan’s ear, Conan nodded and immediately ran out.

And Xiaolan immediately complied.

The iodine wine fell on the handkerchiefs, two of which left brown marks on them, but in one of them, the color gradually disappeared.

“Gone!”

Officer Twilight was shocked.

“Very simple chemistry, Miss Fujii, can you please explain why there is sodium sulfate on your handkerchief?”

At this moment, everyone’s attention focused on Takako Fujii.

And she just silently lit a cigarette.

“This is something I’ve never brought after a doctor’s friend’s house washed it!”

“So you brought it before it was washed or dried?” Didn’t you still sing at karaoke before? ”

“……”

Takako Fujii also knew that she couldn’t explain it.

After all, a normal person will not take sodium sulfate to wash his hands.

“I lost, I didn’t expect to show my horse’s feet so quickly, but how do you know?”

Takako Fujii took a deep breath of the cigarette and spat out heavily.

She now wondered how she had been discovered.

“I didn’t know originally…”

He Yun’s words immediately whetted everyone’s appetite.

“But your behavior reminds me.” _
