"You're researching what the murder weapon is, right?" Guan Shan also leaned over and looked at the strange wound.

Luo Chuan turned his head to look at Guan Shan and said, "This wound is cone-shaped, and it wasn't done by something like a knife. But let's talk about the awl...... It seems to be a little thicker again. It's okay to talk about the weird secret room techniques out there, but if we can't figure this out, it's going to be a problem. ”

Guan Shan nodded: "Well, yes." No matter who we suspect, if we can't find the murder weapon, there is no way to make a verdict. ”

Luo Chuan left the corpse and walked outside the gate.

The footprints on the snow had been lightly covered with sheets, and the caretaker had carefully covered every trace with the sheets.

Luo Chuan followed the road he had walked, approached those huge footprints, lifted the sheets, looked at them, and said, "Guan Shan, look at the blood droplets next to these footprints, which means that the murderer walked with the murder weapon when he left. That is to say, no matter who killed Du Miao among the four of them, the murder weapon should still be on them or in the room. ”

"That being said, I think it's too unlikely to be hidden. If you think about it, the four of them took the initiative to find you to report the crime. No one would be so stupid as to carry a murder weapon with them. Guan Shan believes that this murder case is well planned, and the murderer should not take such a risk.

"But they should be able to guess that as long as they see the corpse, they will be controlled. It was only a matter of time before the room was searched. So, it's impossible for the murder weapon to be hidden in the room? Luo Chuan continued to analyze according to Guan Shan's reasoning.

Saying that, Luo Chuan walked to the gate of the courtyard again, that is, the place where the footprints disappeared, and after checking them one by one, he said: "The amount of blood in these blood drops is not small, I suspect that the murderer killed Du Miao first, and after hanging the body, he made up two more knives, and then immediately walked out of the room." He seemed to do it on purpose, the blood stains on the snow...... What is it meant to express? Is it just to create an atmosphere of terror? ”

"Probably not, this criminal is cautious, every step he takes is to cover up his criminal methods. This kind of person does not take risks for the sake of a certain atmosphere. Guan Shan analyzed the psychology of the criminal, but he couldn't sort out the problem of the murder weapon and blood droplets for a while.

So, he changed his direction and asked Luo Chuan: "By the way, do you have a clue about the door full of nails?" I always felt ......"

As soon as Guan Shan said this, Luo Chuan answered: "I think that's a cover, right?" At that time, we were looking at the door from the side, and the whole room was only the window where the door could be seen. When we saw the door full of nails, we all thought it was nailed. But now no one can confirm that the door was really nailed? If not, then the so-called secret room murder is self-defeating. ”

The two of them walked back to the room in tacit agreement, each squatting on either side of the door.

Luo Chuan stroked the twisted iron nails and said, "The moment the door was slammed open, these pieces of evidence were already destroyed. We have no way of knowing what shape the nails will look like before they hit the door. All that can be seen now are the broken nails and the nail holes in the door frame. I asked Xiaoxue to count it before, and the number of nails and nail holes matched, if the nails next to the door were all disguises, they were not really nailed to the door frame. Then, the murderer used nails to compare the position in advance, first made nail holes in the door frame, and then nailed those nails, as long as half of the nails were made to look like after the door was knocked open, this illusion was completed. ”

Guan Shan also pondered and said, "Well, that's right. But if that's the case, it's bound to make a noise. This is also a problem that Guan Shan has been considering, even if the murderer really nails the door, he will need to knock at least thirty-seven times. If according to Luo Chuan's statement, the murderer first made the corresponding nail hole, and then smashed the nail, that is to sound seventy-four times! Even if half of the sound is blocked, at least the other half should be heard, right?

Luo Chuan paced lightly around the door panel on the ground, thinking hard and said, "This will indeed make a sound...... The sound ...... Is it the reason why the killer needs other voices? ”

Guan Shan's eyes widened: "What do you mean ......?"

"Yes, Moonlight Song. On the one hand, the murderer used the symbol of the moonlight killer to confuse our vision, and on the other hand, perhaps he was masking those voices. We all know that the second movement of the Moonlight is an allegro, and the third movement is an apocalyptos. If you can match that rhythm, the sound of smashing nails can be easily drowned out in the moonlight song. Luo Chuan's eyes shone with brilliance, which was a different kind of brilliance that would only appear in his eyes whenever he had to solve a puzzle.

Luo Chuan looked at the position of the nails on the door frame, imagined the force of these nails when someone hit the door outside, and then continued: "You see, many of these nails are concentrated near the door lock. Because when the door is slammed, the first thing to break is the door lock and hinge. These are the places where the stress is greatest, and the nails are the most damaged. For the sake of this case, the murderer should have demonstrated countless times in advance, so now we can't find much evidence of falsification on the door. ”

"If all of your reasoning is true, then the secret chamber has been solved. The key evidence is the murder weapon. Or...... It is the wooden board used to find the murderer's footprints. Guan Shan said, his eyes already looking at the fireplace in the room, and at the same time showing a worried look.

Luo Chuan understood what Guan Shan meant, sighed and said, "Because there are all snow huts here, and there is a real fireplace burning in every house. The resort also specially prepared firewood for backup. The wood used to make the footprints is estimated to have been burned. ”

"There was no sign of a fight in this room, indicating that when the murderer came in, Du Miao was not too prepared. They may have been chatting in a very peaceful situation, and the murderer suddenly killed Du Miao. When Du Miao bled and fell, he may have touched the window, so there was blood stains on the window. Guan Shan said as he walked to the window at the same time as Luo Chuan.

The blood stains on the window seemed to have been smeared, and there was a bloody handprint next to it. Luo Chuan stretched out his hand and compared it next to the bloody handprint, and then said, "This should be a woman's hand." Could the murderer be a woman? If you have determined that Li Shasha's suspicion is relatively low, then that writer Lin Nan ......"

Guan Shan pointed to a blank space on the middle finger of the bloody handprint and said, "No, this handprint should be Du Miao's own." You see, she wears a large decorative ring on her hand, which is the blank part of the middle finger of the bloody handprint. But she ...... Why do you want to press your own handprint on the window? Is it some kind of signal or cue? ”

Luo Chuan noticed that there was indeed a blank space on the handprint, which made him fall into deep thought again. If Du Miao was facing the window before she died, then she should have injured her back! But the wound on the corpse showed that Du Miao was injured in the abdomen...... Could it be that she turned around after being injured and deliberately pressed this handprint on the window?

No, it doesn't make sense.

But if it wasn't for Du Miao pressing it himself...... That's what the murderer did?

What was the murderer's purpose?

Luo Chuan looked at the window, looked at the bloody handprint, turned his head to look at the door that fell to the ground, and suddenly said with a flash of inspiration: "Guan Shan, I seem to know the reason!" This handprint was pressed by the murderer with Du Miao's hand! ”

"That'...... The reason? Why? Guan Shan asked.

Luo Chuan smiled and replied: "We all think that the murderer is too complicated, but in fact, he is not complicated to that extent at all!" He did this just to make his own plan go smoothly! ”

"How?" Guan Shan looked at Luo Chuan curiously, he didn't expect him to see through the murderer's methods so quickly.

Luo Chuan was also a little excited, he pointed to the window and said, "The reason why this secret room murder case can become a secret room is because of the door full of nails." The door may not be locked at all, but it is just closed casually, and anyone can be a murderer. But if the door is nailed, it's an absolute secret room. We now suspect that those nails were nothing more than a façade and did not nail the door frame at all. Everything is an illusion after breaking in. But to complete this illusion, we have to break down the door! ”

"I see." Guan Shan continued: "If there is no blood stains on the window, there are no handprints, this window is not important evidence, and when we see the door nailed, it is very likely that we will choose to break the window and enter." In this way, as long as the gate is not broken, we will find the illusion of nails when we enter, and the murderer's plan will be in vain. ”

"That's right! That's it! This bloody handprint is just to keep us from entering through the window, and we have to break open the door. It was only when the door was smashed open that the nails were of real use. I think...... I already have a rough idea of who the killer is. Luo Chuan looked at the room where the second captain was with the four people.

Guan Shan also said: "I almost thought of it...... Only that person acted most sensibly at that time. Guan Shan looked at Luo Chuan's gaze and smiled.

Luo Chuan only seems so excited when he solves the case, and the closer he gets to the end of the mystery, the stronger the excitement becomes.

"We now need to know the motive for the crime, and the murder weapon, and that's all that's left." Luo Chuan said and walked back to Du Miao's body again.

He examined the strange and special wound again, and suddenly frowned and said, "This ...... Why is there a faint trail of blood near the wound? What is it? ”

I saw that the wound on Du Miao's abdomen was now a faint stain of blood. This was not there just now, and now it is starting to become apparent.

At this moment, Ke Xue ran back, he was holding his tablet, and when he saw Luo Chuan, he immediately said, "Team Luo, I found it!" ”

Luo Chuan asked Ke Xue to come over and speak slowly, and explained to Guan Shan: "Just now, I asked Xiaoxue to go back to the room to concentrate on investigating something that doesn't seem related on the surface. But now it seems that it should not be completely irrelevant. Let's take a look. ”

Ke Xue's fingers quickly operated something on the tablet, and then said without raising his head: "Team Luo, you asked me to investigate the hostess that the second captain said, and I really found something not very good." ”

Then, Ke Xue said something that happened a few years ago.

About four years ago, there was a popular show about heroes, and the hostess was named Song Yayin. This Song Yayin's hosting style is down-to-earth and generous, her appearance is also elegant and dignified, her voice is very infectious, and she has a strong sense of justice. She is very suitable for this show, and her audience is also very good, and for a while, no one in the entire TV station seems to be able to compete with her.

However, in a complex competitive circle, Song Yayin's excellence and success naturally caused a lot of controversy and jealousy. Some people say that her show is not suitable for the taste of the current public at all, and it will not last long. Some people say that she just won the show by relying on dirty deals.

Ugly gossip abounded, but it did not defeat the hostess, on the contrary, she became more and more frustrated.

It stands to reason that courage is a good thing. But on Song Yayin, it became a catastrophe that could never be recovered.

Just when her career was in full swing, suddenly one day, her voice couldn't speak. After being rushed to the hospital, it was only after she learned that she had been poisoned. Although it is still unknown who the poisoner is, it was certain at the time that it must be someone from inside the TV station.

No matter how good a host is, losing your voice means losing your job. The official covered up such a scandal of internal strife, saying that Song Yayin could not host due to illness, and was replaced by another female host.

Who knows, the audience didn't buy it. The new host, with a sweet voice and a contrived demeanor, is annoying. It's not suitable for such a show at all. So, it didn't take long for the ratings of this show to decline rapidly, and finally had to cancel the show.

That's what most people in the TV station know. But Ke Xue investigated deeper news, that is, Song Yayin, who lost her voice, did not retreat calmly. He was robbed and insulted several times, and his family coerced him to shoot indecent videos. Overwhelmed, in pain and helpless, she finally committed suicide by jumping into the sea on a snowy night.

This sad story is almost unknowable, and the news blockade is very successful. In addition, Song Yayin only has a pair of honest parents, and a younger brother who is studying in a foreign country, no one can do justice for her, or ...... They can't fight either.

Song Yayin's matter seems to have nothing to do with the case in front of her, but the key is that the TV station where Song Yayin used to be is the TV station where Du Miao and several others are now. In this way, things will not be irrelevant, as Luo Chuan said. The motive for the murder is in it!

Luo Chuan listened to the ins and outs of the whole thing, and said to Ke Xue: "Go tell the second captain and bring those people over." I already know who the killer is and what the murder weapon is. ”
