Who are the four murderers in the masked hotel?

The four murderers in the masked hotel killed his wife's husband, Pan Tong, the deceased's student, and Nagakura Magui in order to defraud the insurance money.

The story of Masked Hotel begins with the serial code left by the scene of three consecutive murders in Tokyo. By analyzing the code names of these three incidents, the search headquarters concluded that the fourth murder would take place in "Tokyo Cotesia Hotel". In order to prevent the fourth incident, several searchers were arranged in the hotel to search as waiters.

A blind female guest, a child, first aroused Xintian's suspicion. Judging from all the details, she should be a normal person. After checking out, Piantong voluntarily admitted that he was not blind. I'm looking for my blind husband. Now she is very satisfied with the service of the hotel, which will make her husband feel at ease. With this reason, we can dispel the doubts of Xintian.

A woman named Anye lives in a hotel and holds a photo, calling the person in the photo a stalker. Please tell her when the front desk sees this man. When the "stalker" in the photo came to the hotel, Shang Mei found that this gentleman named Guan Lin was very educated and did not ask about other guests after checking in. For all the guests, Shang Mei went to Anye's room and reminded her not to go near Guan Lin's room.

It took a while for Shang Mei to react. Why did the victim have a photo of the stalker? Maybe Anyo was a stalker and made a fatal mistake. Sure enough, the hotel monitoring showed that Anye was the room to the library forest. Shangmei and Xintian hurried over, but fortunately Anye, who came to catch the rape, only took out a divorce agreement.

Anye is not the murderer, but this incident also made Shangmei realize a problem. Hotel employees often attract guests' disgust. Maybe the killer's target is employees. It's just that this idea is fleeting, and Shangmei didn't mention it to Xintian.

Xintian once investigated the first murder case. At first, it was suspected that the deceased Okabe embezzled public funds and was killed by his accomplices. At the time of the incident, Zhengmu's ex-girlfriend He Qian called Zhengmu's landline, which can be confirmed by He Qian's girlfriend Inoue. Because Zhengshu's home is an hour away from the scene of the murder, Zhengshu was ruled out as a suspect.

But Shang Mei, out of women's intuition, doesn't think ex-girlfriends will call their ex-boyfriends unless someone encourages them. In addition, inspired by the hotel's program-controlled telephone, Xintian believes that Inoue stole the number stored in He Qian's mobile phone, and dialed a nearby landline instead of Masaki's on the night of the murder.

Masaki and Inoue were quickly arrested. After investigation, Inoue had an affair with the victim Okabe, and they cooperated with Masaki to kill people because of their emotional entanglements. But things are not over. In Zhengshu's computer, the police recovered the deleted emails and confirmed that they had conspired with three other people to commit a series of murders. They committed crimes for their own purposes and misled the police by pretending to be a serial murder. When this disguise was uncovered, it was only a matter of time before the first three cases were solved. Only the fourth one is still a mystery.

People in all departments are more cautious, waiting for the murderer to appear. The front desk sent a gift, indicating that it was for the groom, Miss Gao Shan, who was going to hold a wedding in the hotel. Xintian noticed that the gift was wrapped in the wrapping paper of the department store, but it was not from the department store. After inspection, there was no obvious pinhole in the cork, and highly toxic components were detected in the gift red wine.

The focus of the police immediately turned to protecting Miss Gaoshan and her fiance, and deployed staff to strengthen security at the wedding. It's just that Xintian, who deserves the most credit, failed to take part in the operation and had to stay at the front desk.

At the wedding scene the next day, a suspect was successfully arrested, and an envelope containing a note with numbers was found in his pocket. But the suspect claimed that he was only entrusted to deliver letters from the Internet.

At this time, another police officer found a suspected case. The deceased Matsuoka, a dramatic actor, once stayed at the Cotesia Hotel, with a pinhole in his ankle and an unknown cause of death. Xintian was surprised when she saw the poster. This drama poster has not only Matsuoka, but also a tung. Xintian understood and was tempted by a diversion.

At this point, Piantong checked into the hotel again and asked Shangmei to take her to her room. Xintian rushed over and saw Zhang Tong stabbing Shangmei's neck with a syringe. Xintian tugged at Zhang Tong to save Shangmei.

It turns out that a year ago, my heartless boyfriend Matsuoka checked into a hotel. At that time, the pregnant child found the hotel and asked for the room number, but Shang Mei at the front desk refused. After waiting outside the hotel all night, I was cold and tired and had a miscarriage. Therefore, she killed Matsushima and asked Shangmei to be buried with her children.

In the second case, the husband who killed his wife in order to defraud the insurance money was caught; In the third case, the student of the deceased surrendered to the police. The fourth note points to the position of the first case, and a cycle also indicates that all cases have been solved.
