Maolilan's words were like throwing a bomb, causing an uproar at the scene:

"What? Madame is a murderer?! ”

"How is that possible... She, didn't she just come home with you? ”

Everyone changed color in unison, and their eyes were full of disbelief.

Even Conan couldn't help but be shocked:

Xiaolan saw through the truth so quickly?

When the 'Kansai Hattori' didn't know where to squat to find clues, and her 'Kanto Kudo' hadn't solved the puzzle yet, she had already found the murderer!

Conan's gaze became more and more complicated.

Unconsciously, Xiaolan was already able to walk ahead of him with her own strength.

He was both emotional and disappointed, but secretly happy.

But Maorilan was not happy at all.

With tears in the corners of her eyes now, she quietly looked at Mrs. Ikemura, who had turned pale in the crowd, with a sentimental and angry gaze:

"Mrs. Ikemura, I've seen through your murderous ruse."

"You didn't come to my father's office to give a commission, but to use us as witnesses to create an alibi for you."

"I...."Mrs. Ikemura struggled to organize her language braid.

However, looking at the pure tears that glistened in Maorilan's clear eyes...

Somehow, she suddenly felt ashamed of herself, and she stammered for a long time, but she couldn't do the evil act of denying the sophistry.

And Mao Lilan continued to say in her slightly trembling voice:

"Actually, the so-called 'secret room killing' doesn't exist at all, it's an illusion you have designed."

"Because when we visited Ikemura's house and opened the door to this study... Mr. Ikemura isn't dead at all! ”

"He should have just been put to sleep there by sleeping pills, so he looks like he's dead."

"I think that if we extract the stomach contents and blood of Mr. Ikemura and do a toxicology test, we will definitely be able to detect the composition of sleeping pills."

Her words caused an uproar.

At this time, not only Conan, but even the sluggish Maori Kogoro had already understood the truth that his daughter wanted to reveal:

"I see..."

"The dead were killed right under our noses!"

"Because when Xiaolan did the autopsy, we all saw it, and Mr. Ikemura's body only began to turn purple at that time!"

"This proves that he died just now, and not 'within half an hour' as previously speculated."

"That's right."

Maolilan choked up and said the answer:

"The poison injected into the arteries of the neck is highly toxic, and the poison spreads throughout the body as quickly as possible, putting the victim to death."

"So even if the killer kills right under our noses, it's hard for us to notice."

"And because the murderer used sleeping pills to put the deceased to sleep in advance, making him appear motionless, so..."

"We will subconsciously believe that the deceased is dead before we enter the room, as the murderer expected."

As he said this, Maolilan's voice trembled slightly.

Because she was also deceived by the murderer.

When she saw the motionless Ikemura Xun collapsed to the ground with a gentle push, she, like everyone else, subconsciously felt that he was dead.

And then the so-called detective Hattori went up to the autopsy and gave the conclusion that he was dead, and she also preconceived to believe it.

But the truth is... At that time, Isao Ikemura just had a violent attack of the toxin and fell into suspended animation.

Otherwise, the blood will not continue to flow and the lips will not be cyanotic.

Lin Xinyi taught her the way to distinguish fake death, and she should have found out.

As soon as he thought of this, Mao Lilan felt as if he had made some big mistake, and his expression seemed a little dazed.

She was silent and did not speak, and the rest of the conclusions did not need to be said, everyone could figure it out:

"The man was just poisoned and suffocated to death."

"And when that kid from Hattori Heiji stepped forward for an autopsy, Mr. Ikemura already had a pinhole in his neck."

"In that case, the one who had the opportunity to stab Mr. Ikemura's neck with a poisonous needle and inject him with poison..."

Maori Kogoro helped his depressed daughter to complete this reasoning:

"It's just that before Hattori, you're the only one who has ever come into contact with the dead—"

"Mrs. Ikemura Gonge!"

Mrs. Ikemura was silent for a while, her eyes full of panic:

Her murderous ruse shouldn't have been cracked like this.

Because even if the time of death is inferred by scientific autopsy methods, there is no way to accurately reduce the error of the result to less than half an hour.

In this way, the police who came later had no way to confirm whether Ikemura died before she came back or after she returned.

The Maori family, whom she had invited, could serve as a witness that her husband was dead when she returned home.

But I never expected...

In the Maori family she invited to be a witness, there was a forensic science student who knew a little knowledge.

Mrs. Ikemura's elaborate murderous ruse not only failed to work, but also exposed herself to Maoliran in an instant.

"It seems... I was self-defeating. ”

Mrs. Ikemura let out a long sigh of relief.

Her voice was full of relief, and it was clear that she had no intention of resisting any longer.

"Mom... Is this really what you do? Ikemura's eyes were full of shock: "Why did you kill your father?!" ”

"Ahh

She seems to be brewing emotions, and she wants to tell some complex and sad story.

And at this moment...

While everyone was quietly waiting for Mrs. Ikemura to tell her story about the past.

Suddenly, there was a rush of footsteps at the top of the stairs.

With a confident smile bright enough to endorse black toothpaste, Hattori Heiji made his debut:

"Guys, I already know who the murderer is!"

"Uh..." The atmosphere suddenly became a little weird.

Everyone, you look at me, I'll look at you, and in the end, Maori Kogoro reminded with a strange look:

"Well, actually..."

"In fact, the murderer used a very wonderful secret room murder method!"

Hattori Heiji spoke upright, completely oblivious to the strange expression of Maori Kogoro.

He had just run downstairs and rummaged through the trash cans, and within a few minutes, he had found what he was looking for in the same place where he reasoned.

In other words, it only took him a few minutes to crack such a complicated secret room technique.

This kind of speed of solving cases seems to surpass 99.99% of her peers in the world, what does that Maori miss compare to?

As soon as he thought of this, Mr. Heiji Hattori, who was eager to win, couldn't help but feel a wave of happiness in his heart:

"Although I only watched the scene for a while and was kicked out."

"But even if it's so limited, it's enough time for me to see through the murderer's method of murder in a closed room!"

There was a little pride in his voice.

But Mao Lilan was so confused that he forgot to shed tears:

Murder in a closed room?

This case is not a murder in a closed room at all...

How else could he crack a secret room murder method?

Don't... Did I just find out wrong? Is Mrs. Ikemura helping people to take the blame?

The fledgling Miss Maori can't help but feel a little weak-hearted.

With this kind of self-doubt, she didn't question Hattori Heiji out loud, but asked softly in a very weak voice:

"Then, Mr. Hattori... Tell us about your findings? ”

"Haha... Good! ”

Hattori Heiji thought that Mao Liran had already bowed to the wind and was waiting to listen to his own high opinions.

So, he immediately took out the fresh fishing line he had just turned out of the trash can and displayed it in front of everyone:

"There are only two keys in the study, one of which is carried by Mrs. Ikemura who is out, and there is no way to use it by the murderer."

"And the other key is in the locked study, in the pocket of the deceased."

"This creates a secret room, and it is impossible to imagine how the murderer killed Mr. Ikemura with a poison needle, and then left the room without a key and locked the door."

"But in fact, as long as you use this fishing line to design a small mechanism, you can realize this secret room murder trick."

As he spoke, Hattori Heiji took the fishing line and explained in detail the secret room murder technique that he had understood:

"First, kill Mr. Ikemura with a poisoned needle in the study."

Then, tie the key to the fishing line and connect the fishing line to Mr. Ikemura's pants pocket.

"Then, go out of the study and lock the door with the key."

"Finally, pull the fishing line and use the fishing line to slowly send the key from under the crack in the door and into the door."

"The key will eventually get stuck in Mr. Ikemura's pants pocket, and if you pull the fishing line hard outside the door, the fishing line will separate from the key."

"After the fishing line is completely removed, the key is left in the locked study, forming a 'secret room'!"

He excitedly told about this wonderful secret room technique that might only be achieved by those with the ability of the Thread Fruit.

Immediately afterwards, Hattori Heiji said the name of the "murderer" conclusively:

"The prop used by the murderer to realize the secret room is a fishing line, and this fishing line is what I just found in the trash can in the Japanese room."

"Mr. Toshimitsu Ikemura..."

"You just met with us, did you go to the Japanese room?!"

Heiji Hattori took aim at the father of the deceased, Mr. Toshimitsu Ikemura.

His gaze was extremely sharp, as if he wanted to use this momentum to overwhelm the murderer.

However, unlike before, the "murderer" did not kneel in the music and confess his guilt bitterly.

And what greeted Hattori Detective was not the adoring gaze, but a deathly silence.

"What, what's wrong..."

Heiji Hattori finally sensed that the atmosphere was wrong:

"Is there anything wrong with my reasoning?"

"Yes..."

Seeing this "Kansai Hattori", who claimed to be as famous as himself, but invisibly lowered his reputation by the way, Conan's children, who had been watching from the sidelines, finally couldn't help but complain:

"It's all on paper, isn't it?"

"Such a complex mechanism... Can it really succeed? ”

"It's not a question of success."

Mao Lilan couldn't help but connect with the spit combo:

"Even if it works... What's the point? ”

"Using such a complex secret room method to kill people, can it help the murderer create an alibi, or can it eliminate his suspicion?"

"No, the murderer went to great lengths to achieve a secret room killing, just to show off his skills, right?"

She points out the most crucial points:

There must be a reason why the murderer designed the secret room, otherwise it is a secret room for the sake of the secret room.

spent so much effort to use the method of murder in the closed room, but he couldn't help himself at all, did the murderer simply want to act in a detective drama in reality?

"Uh..." Hattori Heiji oozed cold sweat from his forehead.

He wanted to win so much just now, and now that he calmed down and thought about it, it seemed that his reasoning had so many problems.

"But... I've found the fishing line used to make the secret room! ”

"Didn't the murderer kill people in this way?"

Heiji Hattori still had a glimmer of illusion, and it was the evidence that gave him confidence.

"It's not..."Mrs. Ikemura gave the official certification.

"Why do you say that?"

"Because I'm the murderer."

Heiji Hattori: "??? ”

"And, before you even showed up, I confessed my guilt to Miss Maori."

Mrs. Ikemura continues to give Detective Hattori a fatal blow:

"I deliberately threw that fishing line in the Japanese room to blame my father."

"But I didn't expect that this fishing line had no chance of deceiving Miss Maori, but it caught another fish."
