On Wednesday, Shi Zuo gave himself a day off.

Shi Zuocai is a senior in high school. High school juniors who are bulls and horses for their homework are not eligible to give themselves a vacation.

In other words, Shi Zuo only skipped school.

Although he is not a good student, in order to avoid being noticed, Shi Zuocai does have few records of absences.

It's only because Mr. Demon hates to study that Shi Zuo generally appears in the classroom in the image of a stuffy oil bottle.

But today is undoubtedly an exception. When the stuffy bottle woke up again, it was already one o'clock in the afternoon.

He washed his face in the toilet and forced himself to wake up, resting enough to allow the ability to reason to gradually return to his brain.

Then, he sat down in front of the computer non-stop.

Mr. Demon had only one sentence left on the paper, but the Stuffy Oil Bottle understood what he meant almost immediately.

Lin Yushang, who disappeared in front of the public, may indeed not exist at all, but is just a fabricated fake identity.

A person who entered the fashion show "created" a fake identity called Lin Yushang within ten days before the fashion show began, and then used this identity to enter the crime scene.

In this case, all she had to do was to complete the disguise at the scene of the crime and change her original identity, so as to create the illusion that Lin Yushang would disappear out of thin air.

However, although this inference is valid in terms of technique, there are still two unexplained doubts.

First, the motive of the person who pretended to be Lin Yushang is still a mystery.

From the current point of view, she has nothing to gain except to put Liu Yanshi in prison for two days, and such a thoughtful and painstaking crime is definitely not just a prank of the little girls who are angry with each other.

Second, although such a criminal modus operandi can ensure the disappearance of Lin Yushang, the perpetrators still cannot get out of the way.

The audience management of Nicole's fashion show is standardized and strict. According to their official statement, "After the instructions of the staff in the venue, all spectators can only enter the venue between 15:00 and 16:30; After the off-site staff gave the order, they could only leave between 18:30 and 20:00".

- And during the time when the audience enters and exits, the camera at the exit is always on.

In other words, the hapless ghost pretending to be Lin Yushang might be able to sneak into the venue, but she will be kicked out by the staff when the show clears.

As a result, the police investigating the cameras will be surprised to find that there is one more person in the audience who was not there at the time of entry.

Although Shi Zuocai did not have much hope for the reasoning ability of the Australian police, he at least believed that they were not idiots after carefully analyzing the video data for three days.

Shi Zuocai glanced at the report on Liu Yanshi in the "Newcastle Honest People" with great interest, and the result was quite unexpected.

Although Liu's whereabouts on the day of the crime were "unknown", the newspaper clearly wrote that the cameras did not capture her entering the fashion show.

Shi Zuocai lay down in his chair and closed his eyes: although he had hit the nail again, he had a faint feeling that his reasoning was beginning to get on the right track.

Suddenly, he sat up, reopened the statement on the official website of Nicole's fashion show, and rolled the mouse wheel to the middle.

He looked at the passage.

"After the instructions of the staff in the venue, all spectators can only enter the venue between 15:00 and 16:30; After the staff in the venue gave instructions, they could only leave between 18:30 and 20:00. ”

Shi Zuo thought about it for a while, and used the selection function of the mouse to select the "field staff".

This passage seems to just tell Shi Zuocai the division of time for all the spectators to enter and exit the venue, but in fact, it tells Shi Zuocai another message: before the start of the fashion show and when the camera is not turned on, there are staff members in the venue.

If the person pretending to be Lin Yushang was a staff member in the venue, even if she left the venue in the audience, no one would care that she didn't appear in the entrance video. One would only think that she, along with the rest of the staff, entered the venue earlier.

Not to mention that she can also come up with excuses like helping to carry props and leave only after the camera is turned off.

In this way, there is only one flaw left by her - in the eyes of the police, she, as a staff member, entered the venue early; And in the opinion of her colleagues, she arrived later than the allotted time.

And as long as the police can't think of this fantastical modus operandi and ask each staff member about the time of arrival one by one, this only flaw will no longer exist.

More than a year has passed since the case, and Shi Zuocai naturally cannot interrogate all the witnesses at the scene of the crime one by one. But at this moment, a ready-made suspect has been placed in front of Shi Zuocai.

Xu Siwu.

According to Shi Zuocai's original speculation, Xu Siwu should be the target of Liu Yanshi's murder of Lin Yushang again, and the scapegoat for himself with the illusion of absconding in fear of crime. But since Lin Yushang is a false identity and no one was killed in this disappearance case, Liu Yanshi does not need to find someone to excuse himself.

What's more, the video clearly proves that Liu Yanshi did not enter the scene in the audience: she has no partnership with Nicole's fashion show, so she naturally has the most powerful alibi.

And Xu Siwu is a model for Nicole's fashion show. In a sense, she was also a staff member of Nicole's fashion show.

Shi Zuocai opened the relevant news of "Newcastle Honest People" with a familiar way, cut down the whereabouts of the three people involved in the case from the website one by one, and then put the whereabouts of Xu Siwu and Lin Yushang together to make two timelines.

Fortunately, this mysterious disappearance case was obviously used as an after-dinner conversation between the aunts and uncles in a quiet town, and the details were not comprehensive, but they were enough. In this way, Shi Zuo easily summarized the whereabouts of the two.

Lin Yushang arrived at the place at about 18 o'clock in the afternoon on September 19 and checked into the apartment.

On September 23, I cleaned the yard for Aunt Susan. Go to Ms. Anna's house and make a small cake.

On September 24, he cleaned the yard for Aunt Susan again, mentioning that Liu Yan regarded it as his own student registration. Walk Mr. Pollock's dog.

On September 27, go to the school in person to confirm the enrollment file; On the way home, I cleaned the window panes for Ms. Anna.

Between 4 p.m. and 6 p.m. on September 30, he disappeared at Nicole's fashion show.

Xu Siwu, according to the contract requirements on September 25, reported to the fashion show organization meeting 5 days before the start of the fashion show.

On the 25th and 26th, the model was photographed.

From September 28th to 29th, participate in the rehearsal of the fashion show throughout the day.

On September 30, after the end of Nicole's fashion show, she disappeared at an unknown time.

The two appeared at exactly the wrong time. The small size of the town gave them enough time to switch to each other's identities.

Xu Siwu is Lin Yushang. Although the motive for the crime is still unknown, at least she has sufficient conditions and possibilities to create this disappearance.

But is that really the end of it?

Shi Zuocai looked at Xu Siwu's face on the model's profile page, tapped the table with his fingertips, and fell into deep thought. It was a distinctly mixed-race face, with deep eye sockets and slender eyelashes.

Even if she has amazing makeup skills like Liu Yanshi, can she turn herself into a "Lin Yushang"?

By the way, there is also Liu Yanshi: judging from the current situation, she is just an innocent victim in this case.

Could it really be that the expungement of the criminal record, as shown on her immigration certificate, was just an unfortunate coincidence?

Shi Zuocai pressed his temple, reopened the official website of Newcastle Honest People, and carefully browsed the information left by Liu Yanshi.

As he watched, he casually left a timeline on the paper representing her whereabouts. He wanted to see if Liu Yanshi had ever appeared in the same time and place as the other two people, and had a closer relationship.

Suddenly, he stopped his hand and slowly lowered his head towards the paper in his hand.

Liu Yanshi went to Baiqiao Middle School on September 21 to provide Lin Yushang with enrollment information registration.

On September 22, Lin Yushang submitted a study file in China.

On September 30, his whereabouts were unknown. Claims to sleep at home, but there is no evidence.

It was an equally watertight and inconspicuous timetable, with no suspicious contact with the other two involved.

But this kind of flaw is only based on the premise that there are "three" people involved in this case.

The appearance time of Liu Yanshi, Xu Siwu and Lin Yushang still forms a subtle, precise, and perfect time difference.
