"That's right! That is possible! ”

Officer Twilight listened to Shinichi's explanation and couldn't help but suddenly realize.

"Officer Twilight, there's blood in the cardboard box."

Shinichi explained, opening the box and checking it, then pointed to the blood stains inside the box and said.

"Hmm."

Officer Twilight nodded earnestly.

However, according to this statement, everyone who came here at that time had the possibility of committing murder, and it was still impossible to prove that Miss Meimei was the murderer...... Kudo, the most important thing, can you point to the evidence of the murderer, do you have it? ”

Officer Twilight asked again.

"Yes, you said so, so what evidence do you have to prove that I killed Hua Lian?"

Meimei looked at Shinichi with vicious eyes and said.

"That's something I've been trying to figure out before."

Shinichi couldn't help but say:

"Since the prisoner sent a threatening letter and wanted to threaten Miss Hua Lian, why did Miss Hua Lian die on the weapon she was carrying? Theoretically, it is impossible for a prisoner to face Miss Hua Lian with a dagger with her empty hands, right? Therefore, I had suspected the cause of Miss Hua Lian's death before, thinking that the murderer had faked the real cause of Miss Hua Lian's death. ”

Saying that, Shinichi also reluctantly recalled the previous incident of asking Gao Yuan to retrieve the video, and then continued:

"But then I found out that Miss Hua Lian had indeed died from that dagger, and I realized that my reasoning had reached a dead end."

"If that's the case, then you just don't have ...... evidence"

Hearing this, Meimei couldn't wait to speak up, but Shinichi immediately answered:

"However, when I found something behind the pillar, I understood that the murderer was armed at the time."

"What!"

Officer Twilight hurriedly asked:

"Kudo, what the hell is it?"

"It's mercury!"

Shinichi suddenly said:

"Behind that pillar, Mr. Wise and I discovered the presence of some mercury. I guess the killer put mercury in some empty paint bucket here and used it as a weapon. It's just that in the end, the murderer did not succeed in using this weapon to kill Miss Hua Lian, but in the dispute with Miss Hua Lian, he just took away the other party's dagger and killed her. ”

"Mercury? Where is the mercury now! ”

Officer Twilight asked hurriedly.

"It's in that wooden box!"

Shinichi pointed to the wooden box that Shoichi Amano used to put the puppets and said:

"Among Mr. Amano's puppets, there is a mechanical puppet that can go down the stairs by itself. Inside the puppet's body, there is a tube that changes the puppet's center of gravity by slowly moving the mercury inside the tube. This puppet uses this mechanism to achieve the action of turning its heels on its own. ”

"Oh-"

Surprised to druff out his voice, Officer Twilight gave Shinichi a look of reverence.

"When I saw the mercury left in the pillar, I guessed that the murderer must have taken the mercury out of the puppet as a weapon......

"But in this way, doesn't it prove that Amano is the murderer!"

Meimei couldn't help but say.

"So, what did you sneak here to do?"

Shinichi suddenly said:

"Do you want to destroy the evidence left on the puppet before anyone notices the evidence you left behind after the police are gone?"

With that, Shinichi continued:

"And, Miss Meimei, don't you know? Mercury is a silvery-white liquid metal, but it evaporates at room temperature. It is easy to evaporate into the air at room temperature and cause harm, and it has begun to evaporate at 0°C. If you take that large amount of mercury out of the puppet and face the mercury, you should have inhaled a lot of mercury vapor...... The vapor of mercury is more toxic than liquid mercury! ”

Hearing this, Sumimi's eyes suddenly widened, and she was a little overwhelmed.

"As to whether you have inhaled mercury vapor or not, just check it and you will know. And if Miss Hua Lian's corpse can also be found to have inhaled mercury vapor, it will prove that you all had close contact with mercury at that time! ”

Shinichi made the most crucial point.

"Meimei...... What he said...... Is it true? ”

At this time, Misuzu, who had been standing next to her, looked at Meimei in disbelief and said.

In this regard, Meimei seemed to struggle inwardly for a moment, but in the end she still smiled bitterly as if she was fatal:

"Obviously, it's all Hua Lian'...... bad"

"W-What ......?"

Seeing Meimei's confession like this, Meisuzu panicked and froze in place.

"It was Hua Lian who took the mercury out of the puppet and poured it into an empty paint can, intending to use it as a weapon to kill me, and then use the three cardboard boxes to hide my body...... In this way, as soon as the mercury is put back into the puppet, the murder weapon will be gone, and my death will become a cold case......"

Meimei said in frustration:

"She said, 'Since you want me to die, then I can only let you die first...... I was just...... In the process of fighting with her again, I accidentally killed her with her dagger......"

"So, you used the tools she prepared to play such a play?"

Hearing this, Shinichi couldn't help but ask.

"En......"

In this regard, Meimei nodded:

"I was so panicked...... After hiding her body temporarily, I didn't know what to do, but my mother told me at that time that Hua Lian was gone, and there was no way, so I could only pretend to look for her while thinking about what to do...... Finally, I thought of using the contents of the threatening letter ......"

"Not really!"

At this time, Amano, who had been silent for so far, finally spoke:

"It's not like that! Hua Lian's corpse was made like that! ”

"What!"

In response, Officer Twilight and the others couldn't help but shout loudly.

"At that time, Hua Lian, who was stabbed with a dagger, escaped from the elevator room and came to the corridor, where I happened to see it...... But at that time, Hua Lian had already lost her breath...... I saw Meimei's panicked look, and that's how ......"

Amano said hysterically.

"In other words, Miss Meimei killed Miss Hua Lian by mistake, but you happened to run into her. In order to protect Miss Meimei, you tied a kite string to Miss Hua Lian's corpse, pretending to kill people exactly according to the threatening letter? ”

Officer Twilight asked solemnly.

Amano nodded, lowered his head and fell silent.

Seeing this, Officer Twilight couldn't help but sigh, then looked at Sumimi and asked:

"But why did you change that letter to look like a threatening letter? If it weren't for that letter, none of this would have happened, would it? ”

"Because...... Whether it's the honors she won on stage, or Amano...... These belong to me! ”

Meimei said this, and her expression suddenly became hideous.

"What? Is it yours? ”

Officer Twilight was surprised.

"That's right."

Meimei nodded:

"Because I was the first to cross into the world of the Beauty Contest. But no matter what Hua Lian does, even if she enters the industry later than me, she can catch up with me in an instant, and then surpass me...... It's like that for violins, it's like that, it's like that, even beauty pageants are ......"
