Chapter 13 Section VII

There are two things that need to be checked first-whether there are backup keys and secret passages. "I have one key, and there is another one in the guard room. There are only these two in total. There are no other backup keys, and no one should take my one to make a backup key. Of course, in the health room There is no secret way or anything. The floor should never be lifted up, and the ceiling should never be pushed up either." Dr. Sanada's answer was almost within my expectation.Think about it more carefully: Despite Dr. Sanada's denials, there may actually be a backup key, and there may be a secret passage.Although she blurted out "absolutely", there is no such thing as "absolutely" in this world, the focus is on "believe" or "not believe".

"The doctor left the health room at 7:30 in the evening. There was no abnormality in the health room at that time, right?" "Well, of course not, nothing happened at the time." "Ten minutes later the doctor came back to the infirmary and found the murder, right?" "Well, that's right." I actually inadvertently asked her a very important question.But she didn't look like she was lying at all. "I see. I believe the doctor is innocent." I take back what I said in the biology classroom during the lunch break, "Dr. Sanada's True Murder Theory".The murder did indeed take place within ten minutes of Dr. Sanada's absence.Therefore, I don't think she could be the murderer.No, I believe she is not.

"Thank you." Lying on the bed, she thanked her frankly. "By the way, a criminal policeman came this morning. I remember it was a policeman named Patriarch's Valley, right? He has been refusing to believe me, and I find it very annoying." "Does the Police Department of the Valley of the Patriarchs have any doubts?" At this time, there was a very rude knock on the door of the temporary health room.Dr. Sanada asked from the bed, "Who is there?" Then the sliding door rattled open, and the person who knocked on the door replied: "I am Dazang of the Valley of the Patriarchs."

The legendary police department, accompanied by his most proud "self-declared full name", appears here.The timing of his appearance is so wonderful that it is surprising.On the other hand, he showed a very puzzled expression at the situation where the school doctor was lying on the bed and his classmates were taking care of the school doctor. Behind the Police Department of the Valley of the Patriarchs, a little distance away, there is still Osan Chitose Detective as usual. "What's the matter? What is the police department doing?" "Go, it's you again. You really linger, Classmate Qingshan."

"Police, he is Akasaka-san." Miss Chitose corrected him tactfully. "Hmm... yes? Anyway, Aoyama and Akasaka are not much different." The Police Department of the Valley of the Patriarchs is really a stubborn guy.He showed no interest in me at all, and then turned the conversation to Dr. Sanada. "Doctor, what I asked you about in the morning, can you think about it again?" "It's about the keys, right?" Dr. Sanada finally sat up from the bed and explained to me briefly: "The police department wondered if I forgot to lock the door when I left the health room last night. Right? Police department."

"The word 'suspect' is a bit inappropriate. I'm just stating a possibility, a possibility that is enough to explain the unsolved situation at the scene of the crime last night." "Wait a minute, Miss Chitose." As usual, I still asked Osan Chitose detective questions. "As long as Dr. Sanada forgot to lock the door, can the state of the secret room last night be explained?" "That's right. Akasaka-san, listen carefully." Miss Chitose explained the whole story on behalf of the Patriarch Valley Police Department. "I think you have also seen that the lock of the health room at the scene of the crime is just a lock. Generally, like this kind of lock, you need a key to open the lock, but you don't need a key to lock it. .An open lock, as long as the iron rod part is pressed into the lock until there is a 'click', the locking action is completed. Right?"

"That's right, a lock is indeed such a thing." "Well, let me make a hypothesis here—if last night, Dr. Sanada forgot to lock the door. She herself may have thought it was locked, but in fact she forgot to lock it. That is to say, Dr. Sanada put the lock on the door. Near the door, people left—you can just imagine, in this way, the murderer can freely kill people in the health room! Because it is like entering no one's land." While pacing the room, Miss Chitose continued: "The murderer took the victim into the health room through the unlocked door, and then committed murder in the health room. The victim's body was lying on the bed like this. After the murder, just as the murderer was about to leave, suddenly and unintentionally I found the lock on the door. The murderer was overjoyed, so he took the lock to the corridor, locked it with his own hands, and walked away... Is there any contradiction in this logic?"

While gazing at Chitose-san's beautiful eyebrows, I replied: "No, there is no contradiction... Ah, by the way, why did the murderer lock the door before leaving?" Of course, I hope that Miss Qiantui can answer this question, but for some reason, Cheng Yaojin, who came out of the Police Department of the Valley of the Patriarchs, replied: "Ah? Isn't this kind of trivial matter very clear? Of course it is because if you lock it, it can delay the discovery of the murder case, right? It shouldn't be surprising at all, right?" "It's really not surprising at all."

In other words, it's a non-fun and non-weird inference.This kind of thing that is not fun and not strange, it is even more boring to say it from the mouth of the Patriarch Valley Police Department.However, for the police who are determined to solve the case, this should be a very satisfactory interpretation. The Patriarch Valley police department asked Dr. Sanada again: "What's the doctor's opinion? Regarding the situation in the health room last night, should there be no other possibility other than what the Wushan criminal police said?" "Oh, I understand exactly what the police department is trying to convey, but..."

Dr. Sanada seemed to be very confident in his every move, and put on a tough posture that was completely different from her appearance. "My answer remains the same. When I left the health room yesterday, the door was indeed locked. I remember it very clearly, so I can only report to you in this way. If the police department does not believe my statement, then I can't help it either." The Patriarch Valley Police Department showed a slightly confused expression and scratched his head. "Well, but that's strange, there's no other possibility." The tone of the Patriarch Valley police department sounded like they were blaming Dr. Sanada.At this time, shouldn't it be my responsibility to help Sanada-sensei?

"Police department, the murderer's route to the health room is not just the door, is it? There is also a window that I forgot to close! Is that window suspicious? Ah, yes, Dr. Sanada..." Questions that I didn't notice before, I just thought of asking at this time. "Why was the window in the infirmary open?" "The cause was that a medicine bottle was broken. Because the bottle contained a disinfectant with an ammonia smell. Although the part that was spilled on the floor was wiped clean immediately, it was seven in the afternoon. At this time last night, it was still a little muggy, so the temperature in the room was just right with the window open. Later, the smell of the medicine dissipated, and I forgot about the fact that the window was still open." "That's why the doctor leaves the infirmary with the window open, isn't it?" "Well, that's right." If it was Dr. Sanada, this kind of carelessness is quite likely to happen.It should not be fabricated. "That's all right! Police department, the murderer came in through the window that happened to be open." "Don't talk nonsense, boy." The Police Department of the Valley of the Patriarchs simply shook their heads. "The ground outside the window is wet, and there are no footprints. Even if we ignore the issue of footprints, there are still doubts. Why did the murderer climb into the health room through the window in order to kill the victim? This is unreasonable." "There must be some reason for this." Even I don't find it convincing. "So that's the case. Let's assume that the murderer did have a reason. In this way, it means that the victim has to cooperate with the murderer and climb into the health room through the window. Then this victim is really good! He is so good that he wants to cooperate with the murderer. Let the murderer kill himself?" "That's true. It's really a little unreasonable." "Isn't it unreasonable? Impossible." "If the murderer is the victim's accomplice, how about this angle? I heard that the victim sneaked into the school to take pictures of the paparazzi in order to take pictures of celebrities? In this way, wouldn't it be possible to take pictures of the paparazzi in the opposite direction? ?” "I really didn't expect to hear the words of 'Woli' from your mouth. I don't know where you got the idea, but the 'Woli' is not bad, but there are also many doubts: why the murderer Why should the nest be in the health room? Why is the punching awl used as the murder weapon?" "As for the murder weapon, maybe the murderer accidentally picked up something in the health room!" "There's no punch cone in the health room. Right, Dr. Sanada?" "Well, there were no punching cones in the health room," In this case, the murderer would have brought the murder weapon in from elsewhere and committed the murder in the health room.Wasn't this an impromptu homicide? The Patriarch's Valley police department took advantage of the gap, and when everyone's conversation stopped, they said: "Anyway, can you ask the doctor to think about the key again? Then let's take our leave first. Osan Criminal Police, let's go!" The two detectives walked towards the door together. At this moment, the police department suddenly stopped again, raised its right hand lightly and said, "Ah, that's right, that's right. There is one more question." I was secretly startled: the police department couldn't say "my wife..." Something like that?I guess there should be many police departments in the police world who want to imitate Detective Colombo. "Anything else?" Facing Dr. Sanada who was full of surprise, the police department asked that ambiguous question again. "When the doctor ran to the victim last night, did he pick up anything from the victim? Or did the doctor see who picked up something?" "Huh? I didn't pick up anything. If I did, I'd tell the police." "I think so. Don't worry, I'm not suspicious of you. Ah, yes, I'll ask Akasaka-san again. What about you? Did you steal anything from the crime scene?" "You said 'pick up' when you asked the doctor, and 'steal' when you asked me, isn't that a bit too much?" "Don't be angry, don't be angry, I just said it." "I neither stole nor picked up." After I answered with a displeased face, I went back to the carbine and asked him another question. "So there's something missing from the crime scene? Is that right, Police Department?" The Patriarch Valley police department said "no, nothing" in a cold manner, turned around, said "then I'll take my leave first", opened the door and left.Looking at his back, Dr. Sanada said softly: "I wish you a speedy recovery……"
