A woman died in a strange posture in the fitting room of a clothing store.

When the police arrived, they found that the scene was a secret room, the door lock could only be opened from the inside of the fitting room, and at first glance there were no injuries on the body, and no traces were found at the scene, not even the fingerprints and blood stains of the deceased.

So how did the murderer complete the murder without leaving a trace?

According to the staff of the clothing store, the last time I entered the fitting room was when I was cleaning at 8 a.m., and no abnormalities were noticed at that time.

It wasn't until around ten o'clock that the first customers needed to try on clothes that they found that the door to the fitting room was locked. So I invited the master who picked the lock, and opened the door by brute force.

But strangely enough, during the two hours during this period, no one else entered the store.

In order to crack this secret room, Lao Ji invited the investigation professor Mucha to come and assist in the case. Mucha carefully checked the surveillance video of the store that day, and it was indeed as the clerk said that no one entered during the time of the crime.

But he found something wrong with the large circular decoration of the roof, and when he climbed up with a ladder, he found some thin lines in it that could not be detected from below. It seems that the deceased was fixed here in advance before falling onto the couch.

These thin lines are not as strong as fishing lines, but they have a certain amount of toughness, and Mucha suggests that everyone can start with these thin lines. Then they noticed the air conditioning outlet above the wall, but the air outlet was too narrow, and it was estimated that it was difficult for even children to enter.

Back at the police station, the forensic doctor conducted a deep autopsy on the body and found that there was not only a large hole in the chest of the deceased, but also that the body had been soaked in embalming for a period of time.

According to the forensic judgment of the carbon decay cycle, the time of death was on the evening of the 17th of last week, and what was even more bizarre was that on the back of the deceased, two peony flower patterns entangled with each other were found.

Judging from the reaction of life, it was cut with a knife after the death of the deceased, which is obviously a premeditated case.

The police investigation learned that the deceased was Shao Xiaofei, a popular Internet celebrity clothing designer recently. It once became popular on the Internet because passers-by transformed their casual clothes, but later a video broke the news that these passers-by were all models she hired.

After the fire, she set up her own clothing design company, and later the design style was very different from her previous ones.

In order to understand the deceased's social relations, the police found Shao Xiaofei's assistant Chen Yu. She said that Shao Xiaofei lost contact on the 17th of last week on the grounds of retreat and creation.

Because she often does this, disappearing for days at a time, and every time she comes back, she will bring a sample of a newly designed costume, so she is not surprised that she has disappeared for so long this time.

It may be that she was nervous in the face of police questioning, and she was a little unnatural during the whole conversation.

The police also got an important clue from her, the skirt worn by Shao Xiaofei when he died is the main model of their company in the next season. This is a trade secret, and it should be impossible to have a second piece except for the sample designed by Shao Xiaofei himself.

During the conversation, an elementary school apprentice ran in in a panic, Chen Yu seemed to have a very prejudiced version of her, and indiscriminately scolded her. And this scene was seen by the deceased Shao Xiaofei's boyfriend Paul, and Mucha found that there seemed to be something wrong with the way he looked at this little assistant.

After returning to the police station, Cuong quickly investigates this Paul's information, and because of his mixed-race looks and outstanding talent, he is very popular with women in the whole circle.

Although he is Shao Xiaofei's boyfriend on the surface, I heard that he also has some inexplicable relationship with Shao Xiaofei's assistant in private. And now that Shao Xiaofei has been killed, Paul can not only be with Chen Yu openly, but also naturally become the leader of the company's design department.

In this way, this Paul is very motivated and suspicious of committing the crime, but Mucha does not agree with his opinion after hearing it. Because judging from the pattern of the deceased's back, it should not be an ordinary person who can make such an elaborate painting on a person.

But if it was really Paul who committed the crime, then he left this pattern on the back of the deceased, which would only lead the suspicion to himself.

Therefore, Mucha guessed that the murderer should have confused the police's attention by doing so, but it was not ruled out that this painting pattern might have any special meaning to the murderer.

In order to find out the origin of this pattern, Mucha took the pattern on the deceased's back and went to the company's production room to inquire. From the mouth of an embroiderer, I learned that this is an embroidery case diagram of the ancient three-dimensional embroidery method.

Just a few days ago, Paul, the company's designer, also came to ask her about this pattern. The embroiderer's words made the police deepen their suspicions of Paul again...
