Mu Zihan's words made the already very depressing atmosphere in the room even more dull. Pen ~ fun ~ pavilion www.biquge.info because if this is not a simple accident, then it contains too many meanings, and the complexity of the case has also increased.

"So that's what you say, so it's a murder in a closed room?" I asked tentatively. After all, according to Fang Ling's previous description, this study had been locked from the inside before they arrived, in this case, what else could it be if it wasn't a secret room murder?

"That's right, and it's a near-perfect impossible crime, anyway, I still haven't found a loophole in the modus operandi of this case. The only thing that can be said about the imperfections of this case may be the fact that the murderer did not really send Inspector Chu Hengyu on the road at that time. Mu Zihan nodded and said.

"Why do you say this so ugly, it makes it seem like you want Inspector Chu to die." Because what Mu Zihan said was a bit unpleasant, Fang Ling was unwilling to refute.

"To be honest, I also think that what you said Zihan is a bit unkind, after all, Inspector Chu Hengyu was still kind to you when he was alive......" I helped Fang Ling blame Mu Zihan and wanted to take the opportunity to please her.

However, before he finished speaking, he was frightened by the white eyes of Mu Zihan and Fang Ling who were staring at him together, not because he was afraid, but because I also found out that I had made a mistake.

Sure enough, immediately after that, Mu Zihan said angrily: "Think I said something ugly? What you said sounds good, right? You directly said that the person was dead, and he was still 'alive', and he is still rescuing him now! Moreover, I am actually just talking about things, although the words are a bit rough, but it is also true. ”

"What facts? By the way, you say that this case is a near-perfect impossible crime? What's going on? Fang Ling asked suspiciously, she seemed to be more concerned about the slip of the tongue with me just now, which made me secretly relieved in my heart, and almost slapped the horse's hooves.

"The fact is that if the murderer did kill Chu Hengyu at that time, then we don't even have a chance to know who the murderer is from him. Because, judging from the situation at the scene, the murderer must be Chu Hengyu's acquaintance, and it is impossible for an outsider to commit a crime, so if Chu Hengyu is successfully rescued and survives, he can also tell us who the murderer is. When Mu Zihan said this, there was a wry smile on his face, as if solving the case in this way was not his favorite method: "That's why I said that this is this case, so far, what I know, the biggest and only loophole committed by the murderer." ”

"As for why you say this case is near-perfect and impossible to commit a crime, it's because, don't you see the difference between this case and the others?" Mu Zihan paused when he said this.

Seeing that Fang Ling and I didn't answer, they just looked at him, and when he said the answer, he sighed helplessly and explained: "Regardless of the motive and murder weapon of this case, we still don't know anything, even the most basic modus operandi is incomprehensible." It seems that there are many clues left at the scene, but after thinking about it, you will find that these clues not only have no connection with each other, but even each clue points to a broken road at the end, and it is impossible to trace it back to the murderer. ”

With that, he returned to the door, pulled the study door against the wall open, motioned to Fang Ling and I to look behind the door, and then pointed to the broken door lock and said, "A round door lock like this is a very commonly used door lock." Just press the round protrusion in the middle of the round handle behind the door, walk outside the door and close it, and the door will lock automatically and cannot be opened without a key. ”

"Oh, I've seen this lock before, and it does. In that case, this is not actually a closed room murder case, so why do you still say that this case is so complicated? You're a man who likes to play tricks. I said a little excitedly. I always feel that if it weren't for the murder in the closed room, it should be much easier.

"Oh, yes, that's what I thought when I saw this lock. It's just a pity that our ideas are too optimistic. Siyuan, this is not only a closed room murder case, but also a double closed room murder case. Hearing my words, Mu Zihan smiled bitterly, and didn't blame me for saying that, but responded to me with a little crying and laughing.

"Double Closed Room Murder?" I was puzzled and asked, "Isn't this secret room not established?" Where else does the second come from? ”

"Let's not talk about the second part first, let's talk about this first. Although the lock is not established, look for yourselves at the ground of the door, and at the bottom behind the door. Saying that, Mu Zihan only showed us the specific location.

We looked where he was pointing, and saw a reddish-brown stain about half the size of a little fingernail in the middle of the doorway, a little to the right; And behind the door, almost in the corresponding position, there is a line of the same color, extending vertically to the bottom of the door, and the closer the line is to the bottom of the door, the thinner it becomes, as if there is a trace of some kind of liquid left after passing through it.

"What is this?" Fang Ling was a forensic doctor after all, and after careful identification, he said, "Bloodstains." ”

"That's right, this should be the blood splashed on the door when the murderer committed the murder, and then slid down the blood stains that dripped on the ground. I also found such blood stains in many places in the room. Mu Zihan nodded and said, pointing around at the same time: "There are three points on the wall over there, two points on the curtains, and the section of this basic book." Only on the ceiling and on this side of the wall are not. ”

After pointing out, he walked to a position in the middle of the study and explained: "So, the murderer should have been standing in this position at that time, and then attacked Chu Hengyu from behind, so the blood splashing to this side was blocked by the murderer's own body." And after the splashed blood hit the façade, it did not splash, but slipped due to gravity, which means that the murderer's attack was not very strong at that time. Also, judging from the blood stains on the curtains, the curtains of this window were closed when the murderer committed the murder, so why did the murderer deliberately pull it open later? This is also a big doubt. ”

"And the secret room I said was established because of the blood stains on this door." After Mu Zihan returned to his words, he continued: "It can be seen from this bloodstain that this door should have been closed when the murderer committed the murder, so the bloodstains would splash on the back of the door. And according to the principle of human blood, after leaving the human body, a handful will clot within 5-6 minutes. Then, according to the size of the blood beads, the slippage speed is calculated with the disappearance formula v^2=2ah=2gh. In the end, it was concluded that the drop of blood that splashed on the door and slid to the ground would reach the bottom of the door after a minute and a half, and because of the consistency of the blood, it could not drip directly, but should be pulled into a filament and slid off the door. Therefore, if the murderer had opened the door and left at that time, then this drop of blood would inevitably not have been so intact and would have fallen exactly at the door, and would inevitably have been pulled out of an arc. Therefore, this door has not been opened since the murderer committed the murder. ”
