Conan is right, Mao Lilan has actually locked the real murderer in his heart.

She had already sensed something from the moment she found out that this set of footprints was not left by the murderer when he fled:

First of all, this series of footprints can be confirmed to be faked in advance to confuse the public and mislead the direction of the investigation.

Then you can basically judge:

The person who forged this series of footprints in advance was the murderer himself.

Maolilan had previously been determined by observing the characteristics of the footprints, and the owner of the footprints was an adult woman.

The only adult women in the villa are:

Akiko Yonehara, Minori Nakamura, Sonoko Suzuki, Moriran, Belmode.

Of these five people, only Yonehara and Nakamura are the only ones who may have a motive to kill Sugiyama-sensei and can attack him this morning.

Before, because Mihara Akiko was also a victim, and Minori Nakamura found extremely unfavorable physical evidence for her, everyone subconsciously ignored Yonehara Sensei from the list of suspects.

But now...

The footprint was confirmed to have been falsified in advance.

Most likely, the murderer did not escape through the window at all, but stayed in the room.

Akiko Yonehara is more suspicious, and Minori Nakamura is more like being deliberately framed.

"Will it be, will it be... Got it wrong? ”

"People and people cannot be generalized..."

"Perhaps, the murderer's gait of running away looks similar to that of ordinary people?"

Maoliran's expression was extremely shaken.

She couldn't even hold back the ridiculous idea in her head to excuse the suspect.

Because she was so emotional, she instinctively didn't want to believe that her beloved Yonehara-sensei would be a murderer.

"Xiaolan, don't be naïve anymore."

"This series of footprints was forged by the murderer in advance."

Conan sighed helplessly, shattering the last vestiges of Maolilan's illusions:

"Remember what you found, the pair of slippers that the murderer left outside the door?"

When Maolilan was chasing the murderer, he found that the murderer had left his slippers in the snow outside the door.

Everyone thinks that the murderer deliberately changed his slippers at the door in order to escape into the house and not be found out that there were snow chips and water stains on his shoes.

And Conan noticed more from this detail:

"The act of changing slippers is not surprising in itself."

"But Xiaolan, have you ever thought about it:"

"Why did the murderer throw the changed slippers into the snow outside?"

"You have to know that the shoe rack for clean slippers is in the hallway, and if you want to change clean slippers, you have to open the door and walk a few steps inside."

"Why did the murderer take off his slippers outside the door, walk barefoot into the door for several steps, and then change into clean slippers?"

"When a normal person is being chased and running away in a panic, he should subconsciously run in with slippers, and then hurriedly change into a random pair of shoes from the shoe rack in the entrance, right?"

"This—" Maolilan's expression changed slightly.

She vaguely understood what Conan meant:

"The killer did this because she didn't want to enter the villa in those snowy slippers."

"Because of that, those snow-stained slippers? It will leave snow footprints on the floor of the villa. ”

"Heating in the villa? The temperature is higher. ”

"If it's a snow footprint that has just been left, the snow dust will definitely not melt yet."

"If it's a footprint that was forged or left in advance? How many minutes? The snow chips will melt into water stains. ”

"And if we see indoor footprints without snow chips, only melted water stains..."

"Will it be easy to perceive? These footprints are not just left. “

"So..."

"In order not to be noticed by us, the murderer deliberately left dirty slippers outside the door? Carefully did not bring the snow chips into the door. ”

"It's freezing outside the door? The snow chips on the slippers don't melt and look like they've just been abandoned. ”

"But the fact that there are no three hundred taels of silver here can prove it..."

Maorilan reluctantly admits the reality:

"The footprints were forged in advance, and the real murderer simply escaped through the window."

"Ms. Minori Nakamura is not a murderer."

Excluding Minori Nakamura? The remaining suspects? But it's only Akiko Yonehara.

"The only thing that can't be explained now is why Sonoko's confession mentions that when she entered the door, Yonehara-sensei was lying on the ground in front of her, and the murderer attacked her from behind."

"Unless Yonehara-sensei knows how to doppelgänger, she can't"

"It seems incredible."

"That's why we ruled her out in the first place."

"But Sherlock Holmes said: Eliminate all impossibilities? The rest, no matter how unbelievable, must be the truth. ”

Conan's gaze became solemn.

He used his wild imagination? Guessed the trick used by the murderer:

"It's a hoax."

"The garden only glanced at it at the time and saw 'Yonehara-sensei' lying on the floor? He was then attacked and unconscious. ”

And in such a short period of time, she may not have time to confirm at all? The person who fell in front of him was not the real Yonehara-sensei. ”

"After all? In the room at the time: "

"Except for Sonoko and Yonehara-sensei? There's a third person, isn't there? ”

"You mean..."Moriran couldn't help but shudder, "It's the dead Sugiyama-sensei?" ”

"That's right."

Conan boldly guessed:

"Yonehara-sensei must have made that corpse into himself."

"It's easy to do by draping the corpse in your own clothes and covering the corpse's face with a wig."

"At first glance, the garden will definitely subconsciously think that it is Yonehara-sensei who has passed out."

Mr. Yonehara used to have short hair, but now he has long hair.

This couldn't help but catch Conan's attention.

Of course, Yonehara-sensei may have simply changed his look.

But without waiting for Maolilan to question, Conan continued:

"It's a bizarre speculation, and there's no evidence to prove it."

"But it's also easy to verify."

"We just need to ask again if the garden saw the face of the so-called 'Yonehara-sensei' at that time."

"If you look at whether Mr. Yonehara is wearing a wig or not, you can almost judge the feasibility of this trick."

"And once the feasibility is confirmed, plus the previous investigation and reasoning, the murderer can almost be confirmed."

By now, the facts of the case are clear:

Yonehara-sensei killed Sugiyama-sensei first in the morning and hid the body under the bed.

Arriving at the villa at night, she hid the evidence in a down jacket in advance of Minori Nakamura, and faked footprints in advance, creating the illusion that the murderer jumped out of the window and escaped.

Combined with the trick of misleading the garden's sight, this not only cleared Mr. Yonehara himself, but also made Minori Nakamura carry the black pot for her, becoming the number one suspect in the eyes of everyone.

This can be described as a very clever murderous ruse.

"Still, I still feel that something is wrong..."

Mao Lilan combed through the facts of the case from beginning to end, and frowned tightly:

Trickery is indeed clever.

But why did Yonehara-sensei go to such lengths to use such a trick?

is another fake footprint, another frame-up, and the risk of exposure, acting such a bitter trick.

Just to exclud oneself from suspicion?

Why bother?

Wouldn't it be safer and less laborious to secretly dispose of the body and destroy the evidence than to do so?

"Could it be that she has a grudge against Nakamura-sensei?"

"So you want to kill Sugiyama-sensei at the same time, and by the way, Nakamura-sensei will be imprisoned?"

The more he thought about it, the more he felt that something was wrong.

But Conan had already vaguely thought of something:

"Xiaolan, I think, the purpose of Mr. Yonehara's acting in this play..."

"I'm afraid it's to scare her next target out."

"Remember Minako Mochizuki's suicide?"

"We discussed it when we were together before, and the murderer was probably avenging Minako, so Mr. Sugiyama did it."

"But now it seems that there may be more than one person involved in Minako's death back then, and Sugiyama-sensei."

"But Mr. Yonehara doesn't know who the second person is."

"That's why she deliberately acted in such a play."

"With such a terrifying serial murder method, under the back of the hands of the three victims, the name of 'Minako' was left."

"In order to deliberately create a terrifying atmosphere, to scare the 'second person' into revealing his true form."

"And at the time..."

Conan's reasoning is whimsical and eclectic.

That's a nice way to put it.

To put it mildly, it is that there is not sufficient evidence to support it.

But I have to admit that no matter how bold his imagination is, his reasoning can perfectly explain the details of the case:

"At that time, Shimoda-sensei reacted the most."

"I noticed that when he exclaimed because of the name 'Minako', Yonehara-sensei looked at him strangely."

"So I guess she designed this play to surprise the second murderer of the year, so that she can continue to commit the crime."

"Otherwise, there is really no reason for Mr. Yonehara to go to such great lengths to take the initiative to expose the existence of that corpse and let himself enter Mr. Lin's sight in advance."

"You know, Mr. Lin is the management officer of the Metropolitan Police Department."

"It's too late for the ordinary murderer to hide in front of him, how can he take the initiative to provoke an incident?"

"yes," Maoriran nodded.

If things are really as Conan guessed, Yonehara-sensei did this in order to surprise the target and continue to commit crimes.

Well, some doubts seem to have an explanation.

"I see!"

Maorilan suddenly realized something.

She finally noticed what had been making her feel wrong:

"It's Yonehara-sensei's act of blaming Nakamura-sensei!"

"If she really wants to blame Nakamura-sensei, then she shouldn't have hidden a rope in Nakamura-sensei's down jacket at all, and she shouldn't have left fingerprints on that reagent bottle."

"Because as long as you identify whether there is any dander from the garden on the rope and whether the fingerprints on the reagent bottle match Nakamura-sensei, you can prove whether Nakamura-sensei is the murderer or not."

"Only leaving a reagent bottle with fingerprints wiped off makes it even more inexplicable."

"And Mr. Yonehara is hiding ropes and leaving fingerprints on the reagent bottle, which means..."

Mao Lilan gradually guessed through Mihara-sensei's thoughts:

"Yonehara-sensei didn't really want to blame Mr. Nakamura at all."

"Blaming Mr. Nakamura is just to temporarily push a murderer out and divert everyone's attention."

"According to her expectations, since the 'murderers' have been caught, everyone will naturally relax their guard."

"At this point, she can take the opportunity to attack the second target."

"And at this time..."

"At this time, Mr. Nakamura, who was regarded as the murderer, was still under guard, and if anyone dies again, then the suspicion that she is the murderer will be self-defeating."

She paused slightly, and her tone became extremely heavy:

"The conspiracy to blame Mr. Nakamura is bound to fail, and Mr. Yonehara must know this."

"And not only did she do this, but she also deliberately left ropes and fingerprints, which can give Nakamura a clear name and prove that she is the murderer."

"Mr. Yonehara, this is equivalent to 'turning himself in.'"

"So even if Mr. Lin is here, she dares to continue to commit crimes."

"Because Mr. Yonehara doesn't care at all, whether he will be arrested after killing someone."

Mao Lilan's face turned pale:

"She's determined to avenge Minako..."

"Whatever it takes."
