"Lin Police Department, this is the list of passengers you need, please take a look!" said Megumi Ohno as she handed over the list of passengers for the second half of the Senhoua train to Lin Xiuyi.

After Lin Xiuyi took the list, he glanced at it roughly, and then nodded with satisfaction. The list is marked with the passenger's name and the carriage they are in. Lin Xiuyi saw the name of Yasuyuki Nantian at a glance from this list. Mr. Yasuyuki Minamida, who was extremely enthusiastic about Sakurako Takudai, lived in the same carriage as Sakurako, the first discoverer at the scene of the crime, and Erika Shiraishi, the victim. However, their boxes are not like adjacents, and the passengers living in the middle two boxes are all surnamed Kakiya, and if expected, these three passengers should be from the same family.

The carriage in which Sakurako Takudai was located was the sixth carriage of the entire Senhouza train, and if they were arranged in the order from front to back, they were the box of Sakurako Sakurai, the first witness, the box of Erika Shiraishi, the two boxes booked by the Kakiya family on a family trip, and the box where Yasuyuki Minamida was.

In the next seventh carriage, in addition to one foreign guest, there was also Shohei Kono, a bureaucrat of the Ministry of Foreign Affairs whom Hayashi Shuichi had met at dinner, while the other three boxes were vacant.

Lin Shuichi's box is located in the 8th car, and there are only Lin Shuichi and another passenger named Yasuo Hashimoto in the whole car, as for the other passengers in the same class, they have already gotten off the train in advance at Iwaki Station halfway, and there is no intersection between their disembarkation time and Erika's death time, so the possibility of these passengers who got off the train committing crimes can basically be ruled out.

As for the remaining ninth carriage, it is the most luxurious box on the entire train. The entire carriage was occupied by only one guest, Hirazo Ishibashi. The identity of this person, Lin Xiuyi, is unknown, but it is obvious that the other party should be very rich. After all, the price of Cassiopeia's top box is indeed unaffordable for office workers like Lin Xiuyi. But even so, the other party is still suspected of killing Erika Shiraishi.

Although Lin Xiuyi did not confirm whether the deceased had been sexually assaulted before his death, the deceased did not have other obvious injuries except for the fatal strangulation marks on his neck. This basically reflects that the deceased did not struggle violently at the time of the killing. If it is a love killing, most murderers should not treat the deceased's body like this, and if it is a robbery, there is no trace of violent struggle. So neither of the above motives is likely.

Just when Lin Xiuyi decided to talk to all the suspects first and make a decision, Megumi Ohno took Shohei Kono to find Lin Xiuyi. As soon as he saw Lin Xiuyi, Kono Shohei asked Lin Xiuyi with a little excitement: "Did something happen, someone was killed, right? Is the murderer hiding in the car......?"

Lin Xiu looked at Kono Shohei expressionlessly, no matter what Kono asked, Lin Xiuyi didn't say a word, until Kono realized that the atmosphere between the two was a little wrong, and then he closed his mouth in embarrassment, Lin Xiuyi asked Kono unhurriedly: "Kono-kun, I want to ask, what have you done in the period from eleven o'clock last night to one o'clock this morning?"

"Huh, what are you kidding?" Shohei Kono was stunned for a moment, then replied with a smile.

"I'm sorry, it's not a joke! How did you know that there was a murder on the train, how did you know that the murderer was still hiding on the train, and if you can't show an alibi, I'll have to list you as a key suspect. Lin Xiuyi asked Kono Shohei with a solemn expression.

"Well, after I separated from you yesterday, I went straight back to the box to sleep, and then ...... And ......," Shohei Kono replied with a little nervousness.

"Sleep, is there any way to prove that you are sleeping in your own box, if you can't prove it, how do I know if you are lying?" Lin Xiuyi still said without a smile.

"This ...... This ......"

"Mr. Kono, maybe I can understand it this way, but you just know my identity as a police officer and want to come here to get some first-hand information, and I don't know if you plan to use it as your own talking point in the future, or if you want to do something else. But please remember that there is a very serious murder case on this train right now, and if everyone walks around as casually as you do, it will seriously interfere with the police search work......"

Lin Xiuyi taught Kono Shohei a lesson mercilessly, Kono's face was extremely embarrassed, Lin Xiu turned around angrily and left, leaving Kono in place.

It is not for nothing that Lin Xiu is angry, Kono is a passenger who lives in car No. 7, if even he knows that there has been a murder on the train, then how many people on this train do not know about it? If these suspects are allowed to walk around the carriage at will and pass news to each other, then it will probably be easier for the real murderer to cover up the evidence of his crime. Therefore, Lin Xiuyi must curb this kind of symptoms.

It seems that it is impossible to count on the staff on the Cassiopeia train to maintain order among the passengers, and now the investigation of all the suspects involved can only be completed as soon as possible.

Lin Xiuyi picked up the passenger list and browsed it, and quickly decided on his next investigation target, that is, Nantian Yasuyuki, who was also in the No. 6 car, since yesterday afternoon, Lin Xiuyi has always felt that this Nantian Yasuyuki is a little strange.

Lin Xiuyi is not jealous of Nanda Yasuyuki's overzealous enthusiasm for Sakurako Takudai on the train, if you use an analogy, if Nanda Yasuyuki's behavior takes place in a bar or nightclub, Lin Xiuyi will not feel unnatural at all, because it is originally this kind of place, but if Nanda Yasuyuki behaves in a tea ceremony house similar to that in a bar or nightclub, then it will be a little abrupt.

Judging from Yasuyuki Minamida's performance yesterday, this guy is basically pursuing Sakurako Mazui unabashedly, although there are countless scenes of love at first sight in the movie, but in reality it is always rare. Moreover, the deceased Erika Shiraishi was too enthusiastic about Yasuyuki Minamida, why is this? Why is Erika Shiraishi so enthusiastic about the relationship between Yasuyuki Nanda and Sakurako Takurii. And what is Sakurako Tazui hiding?

With this suspicion, Lin Xiuyi knocked on the door of Nantian Yasuyuki's box.
