Chapter 4 Chapter Four

Chizuru looked at him, stunned.Is it really possible to solve things just by listening to the narration?The famous detectives in detective novels all have superhuman reasoning ability, even so it takes a lot of setbacks to find the truth.Although I don't know how powerful the Chamber of Secrets collector is, it's a little strange that he can solve cases at a speed that surpasses the speed of famous detectives in detective novels.Could it be that he is just an exaggerated paranoid? Chizuru thought in disappointment, while the Chamber of Secrets collector had already begun to explain:

"The key to my ability to solve the incident is the mystery of Mr. Kimizuka's watch, which the police believed was taken by the prisoner. The police believed that the watch was very expensive and worth stealing, so the prisoner took it, right? However, as Chizuru said, Kimizuka-sensei's watch is just an ordinary item, not worth stealing. Here, it can be speculated that there is something important to the prisoner hidden behind the watch cover, and the prisoner took it away if he wanted to get it. A watch, eh? But the question is, is there a place to hide something important on the back of the watch cover! That leaves no clear answer to the mystery of why the watch was taken.

"Usually when we can't find a clear answer, we should wonder whether our question itself is wrong. Now it seems that we have to doubt that it is wrong to ask why the prisoner took the watch." "—what, the question itself is wrong?" "Ever thought that the prisoner didn't actually take the watch?" "But, in fact, the watch is indeed missing. It would be even more strange if it wasn't taken by the prisoner?" "It's also possible that Mr. Junzuka didn't wear a watch." "—Kimizuka-sensei didn't wear a watch originally? That's impossible. There is a white part around the wrist of the left hand that hasn't been tanned. No matter how you look at it, there are traces of a watch!"

The Chamber of Secrets collector smiled: "It seems that I said something wrong. I want to say that Mr. Junzuka may not have worn a watch 'yesterday'. From the tanned white part, it is true that Mr. Junzuka usually wears the watch on the Left hand. But, is it possible that he didn't wear it yesterday? Mr. Kimizuka wears a long-sleeved shirt with sleeves reaching to the wrist, so no one would notice that he didn't wear a watch? I started my reasoning based on this assumption." "—didn't wear a watch yesterday? Why?" "First of all, do you forget to wear your watch at home? However, I heard that in Chizuru's music class yesterday, Mr. Kimizuka was still complaining that the tram to work was a minute late. It can be seen that the teacher must be wearing a similar watch. So, I must have worn a watch other than a watch yesterday."

"A watch other than a watch?" "Like a watch, it can be carried around without being worn on the wrist, such as a pocket watch." "Ah, is it a pocket watch?" Uncle muttered. "Ms. Kimizuka bought a pocket watch and stopped wearing it yesterday. Because the teacher has a big wall clock, Mr. Junzuka doesn't need to take out the pocket watch to check the time during class. Naturally, Qianhe didn't notice it yesterday. "Mr. Kimizuka wears a long-sleeved shirt, and the pocket watch should be in the breast pocket. As we all know, the pocket of the shirt is on the left side. That is to say, when Mr. Kimizuka was shot, the pocket watch served as a protective shield for the left chest. Therefore, even if the bullet The bullet hit the left chest, which should have been blocked by the pocket watch, and could not penetrate the heart. Unfortunately, the bullet passed through the heart, and the pocket watch was gone.

"What exactly is going on? "There is only one possibility. The bullet that pierced the heart was not fired when Qianzuru witnessed it, but after that, Mr. Junzuka lost the ability to resist and the pocket watch was taken away!" "——The bullet that pierced the heart was fired after Junzuka-sensei lost his ability to resist? When exactly? Also, if the bullet did not penetrate the heart when Chizuru witnessed it, where did the bullet go?" "Qianhe's eyewitness statement said that the prisoner swayed when Mr. Kimizuka was shot twice. Both shots must have hit Mr. Kimizuka, but the first shot was blocked by the pocket watch on the left chest. He was shaken by the bullet but was not injured. The second shot hit the right chest, and Teacher Junzuka fell to the ground. Teacher Junzuka was injured and could not move. The prisoner thought the teacher was dead and fled the scene immediately.

"However, Mr. Junzuka was not dead. The teacher was worried that the prisoner would strike another fatal blow, so he had to stand up as hard as he could and lock the door from the house. Because Mr. Junzuka collapsed near the door, he didn't need to crawl over when locking the door, so there was no need to climb over to lock the door. No blood was left. If Chizuru hadn't reported to the dormitory management room but had continued to peek at the window of the music room, she should have seen Mr. Kimizuka stand up and lock the door, and then fall down again." "Then, when was Mr. Junzuka's gunshot wound in the heart caused?"

"It was after the music room door was opened. After the door was opened, the prisoner knew Mr. Kimizuka was not dead, and worried that the teacher would reveal who the prisoner was, so the prisoner took the pocket watch from his breast pocket and shot in the left chest. "Just like that, after the door was opened, Mr. Kimizuka was shot a third time in the left chest and died on the spot. However, the gunshot wound caused by the third shot was mistaken for one of the first two shots. At the same time, Mr. Kimizuka It was also considered dead when Qianhe witnessed it. In this way, the secret room condition was established.

"Finally, who was the one who fired the third shot? After the door was opened, the janitor accompanied Chizuru to the principal's office to call the police, and then returned to the back office. During this period, only Mr. Hashizume was there. The one who fired the third shot at Kimizuka-sensei was none other than Hashizume-sensei." "Teacher Hashizume did it..." Qianhe gasped.He is a young and cheerful English teacher who is loved by Chizuru and many other students! Uncle Keisuke began to retort: ​​"But, Mr. Hashizume has an alibi. He poured tea in the back room at seven o'clock, and chatted with the school staff until seven nine. Those who were still in the back room before nine o'clock, in just one minute Within a short period of time, go to the music room, knock down Mr. Junzuka and escape, it is impossible in terms of time."

"Yes. So, the prisoner who fired two shots at Kimizuka-sensei was not Hashizume-sensei, Hashizume-sensei only fired the third shot!" "what……" "Mr. Hashizume left the back room at 7:9. On the way back to the duty room, he met a prisoner who came from the music room. Teacher Qiaozuo learned what the prisoner had done, and then let the prisoner leave with the gun for him. Prisoner It was the person that Mr. Hashizume wanted to protect. Later, as soon as he returned to the duty room, he ran into Chizuru who came to report the incident. Chizuru and the prisoner basically set off from the vicinity of the music room at the same time. Why did Chizuru arrive at the duty room before meeting the prisoner? Hashizume-sensei is much slower? Obviously, it’s because the dormitory doors and windows are locked and you can’t pass through, so you have to go around a detour. Teacher Hashizume should be surprised to hear what Chizuru said about what he witnessed, right?”

In Chizuru's mind, the image of Mr. Hashizume at that time emerged.After listening to Qianzuru's words, Mr. Hashizume showed a look of astonishment, but it was not the stimulation of knowing that Mr. Kimizuka was shot, but knowing that the crime was witnessed by Qianzuru - and the prisoner he sheltered may also be attacked by Qianzuru. See why. "Hashizume-sensei was going to check the situation at the scene, hid the gun that was kept by the prisoner - it should be put in the pocket of the coat - and went to the music room with Chizuru. When we arrived at the music room, Kimizuka-sensei locked the door in the room .” Knowing that the door of the music room was locked, Teacher Hashizume's face stiffened—not because he thought the prisoner was inside, but because he was worried that Mr. Kimizuka was still alive and locked in the room, and might reveal the prisoner's name. "Use the key brought by the janitor to open the door. Mr. Hashizume felt Mr. Kimizuka's pulse. As expected, Mr. Mr. Mr. Kimizuka was not dead yet. But Mr. Hashizume lied and said Mr. Mr. Mr. Mr. Mr. Kimizuka was dead. Then, in order to divert the janitor's attention away from Mr. Kimizuka, Mr. Hashizume also suggested that he and the janitor search the music room to find the prisoner who was not in the room at all. Then, find an excuse to put the janitor and Mr. After sending Chizuru away, she took out the pocket watch that blocked the bullet from Mr. Kimizuka's chest pocket, fired a third shot into the heart with the gun hidden in her body, and killed the teacher. The pocket watch that blocked the bullet was taken away by Mr. Hashizume . "Ms. Hashizume didn't realize that his actions had caused the phenomenon of the chamber, and he only wanted to give a fatal blow to Mr. Kimizuka, who was still alive and might reveal who the culprit was. "Also, I heard that the fingerprints on the doorknobs in the room and corridor have been wiped clean, right? That was done when Mr. Hashizume was alone, but the purpose was not to wipe fingerprints, but to wipe Mr. The blood stained on the doorknob when the door was locked. Because once the blood is found, you will know that Mr. Junzuka locked the door by himself, which means that Mr. Junzuka is still alive after being shot twice, even when Mr. Hashizume opened the door—that Mr. Hashizuka The lie that Mr. Junzuka was dead after the teacher checked his pulse was also exposed. The fingerprints were wiped off at the same time when the blood was wiped. The doorknob on this side of the corridor was not stained with Mr. Junzuka’s blood. There is no need to wipe it, but only the interior door Hey, not wiping the doorknob of the corridor is worried that people will feel illogical, so Mr. Qiaozuo also wiped the doorknob of the corridor side in order to cover up. That way, the fingerprints on the corridor doorknob when opening the door will also disappear. Put your own fingerprints on the doorknob. "It's a pity that with the current search technology, there is no way to detect the wiped blood. Maybe an epoch-making method will be developed in the future. Even if the blood is wiped, just spray some detection potion, and the blood will glow. If it arrives In the era when any search was carried out in that way, in this secret room incident, by detecting the blood stains on the doorknob, it was immediately clear that Mr. Kimizuka locked the door with the revolving doorknob." "If we can develop that magical method, we police will be much more relaxed..." "Then who fired two shots at Mr. Kimizuka? As mentioned earlier, after the criminal committed the crime, he ran into Mr. Hashizume who was returning from the back room to the duty room on the way to escape from the music room. However, after careful consideration, such an encounter It's a bit puzzling. If you compare the school building to a huge 'E', the back office and duty room are on the vertical line, and the music room is on the east side of the middle horizontal line. That is, the prisoners go vertically from the east of the middle horizontal line However, the prisoner broke through the window in the front corridor of the music room and should have escaped from the scene through the same window, that is, there is no need to escape from the east of the middle horizontal line to the direction of the vertical line. Even so, the prisoner also I did it, and ended up meeting Hashizume-sensei. What's going on here? "Go from the east of the middle horizontal line to the direction of the vertical line, and the intersection point is the front entrance. From this point, we can know that the prisoner escaped from the east of the middle horizontal line to the direction of the vertical line, not from the window of the corridor, but from the Escape through the front porch." "To escape from the front entrance? However, the front entrance door will also be locked at night. Only Dojima's janitor and the principal have the keys." "So, the prisoner is one of them. The Dojima school staff has an alibi, so the prisoner is the principal. The principal has a disabled right foot, so he must be wearing a cane. Therefore, the principal broke the window in the corridor to show signs of intrusion, but it is not. There, he opened the door of the front entrance to enter the school building. After the attack, he also wanted to sneak through the front entrance, so he walked from the east of the middle horizontal line to the direction of the vertical line. Mr. Hashizume. After knowing what the principal was doing, Mr. Hashizume decided to cover up the principal. Because if the principal is arrested by the police, it will become a big scandal, and the parents will let the students collectively withdraw from school. In this way, unlike government schools, The private school will only end in closure. Teacher Hashizume will also lose his job. In order to keep his job, Teacher Hashizume chooses to cover up the principal and shoots Mr. Kimizuka with a fatal shot..."
