Bai Xin didn't sleep well all night, tossed and turned, and almost rolled under the bed.

In her dream, there was a person, against the light, with a shadow on his back, from head to toe, the black shadow was stretched into a narrow and long, like a floating seaweed, covering most of her body.

Bai Xin was afraid of him, so he instinctively retreated.

She scrambled and fell to the ground, sinking into a heavy shadow.

Bang bang bang.

Bai Xin's heart was beating faster, like a deer crashing, I don't know whether it was panic or inexplicable throbbing, and the emotions were hazy.

It's just that she can't go back anymore.

Who is he?

Like a night traveler, stepping on the night, coming from hell......

There is always an inexplicable sense of oppression in his body, which makes it difficult for Bai Xin to move an inch.

And at this moment, the man turned around and handed his palm to Bai Xin, and there was a mint candy in his palm.

Sugar?

As soon as Bai Xin raised his head, he saw the outline of this person's eyebrows, it was actually Su Mu?

Su Mu half-curled his index finger, pushed his thin-rimmed glasses, and said in a low voice: "You think I'm a murderer?" ”

Bai Xin didn't speak, thinking to himself: You know so many things, either you are a person with very strong logical thinking; Either that's behind this incident, and you can't be trusted.

"This question is a score question. If you want to confirm the identity of my murderer, then come up with evidence, without evidence, whether it is a suspect or a real murderer, you can have the qualification to get away with it. ”

"I'll find out the truth." Bai Xin refused to admit defeat and shouted loudly.

She woke up suddenly, with the back of her hand on her forehead, wiping away her sweat.

It turned out to be a dream, but how could I dream of him?

Could it be that Bai Xin was subconsciously suspicious of Su Mu?

How could it be so coincidental that the murderer lived next door to her?

And how can you convict the other party based on intuition alone, maybe it's just a simple ...... Su Mu is smarter than her?

The man...... Thinking about it like this, she was even more unhappy.

Bai Xin cheered up, washed up, and rushed to the unit.

Anyway, she was curious about the mysterious way to die.

Senior Brother Wang put on gloves, tightened the gap between his wrists, and said in disgust: "I've watched it so many times, and I haven't finished reading it yet." If it is not cremated, it will rot, or it will be put in the freezer and kept for the winter like storing pork. ”

Xiao Lin was about to be disgusted to death, and waved his hand again and again: "Senior Brother Wang, don't say it, okay?" I don't even dare to eat frozen dumplings with pork filling. ”

"Huh? Have you been eating frozen dumplings with pork stuffing lately? I don't know how to cook and come to my brother's house to eat, my brother's cooking skills are ancestral, and my great-grandfather is said to have worked as an errand in the imperial dining room in the palace before. ”

"What errand?"

"Boiling water."

"......" Xiao Lin didn't expect him to be so able to speak, and he was speechless.

Bai Xin interrupted them, and once again grabbed the wrist of the corpse, the skin on it was smooth, and sure enough, there was no trace at all.

She knows very well how blood congestion is formed, and before death, the blood in the body is constantly circulating, and if it is affected by external forces, it will cause capillaries to break, forming blood accumulation.

When a person dies, the blood stops working, and the part of the blood vessel that bursts becomes a blood clot, which coagulates into a bruise that remains under the cortex and turns dark brown. However, on the contrary, if it is after death, no matter how hard you try, it will not form deep contusion marks, or even bruises.

This is a good proof of whether there was a fight or struggle in her life, and now, it seems that none of the knowledge she has learned can be applied to this corpse.

A corpse, with only neck strangulation marks on her body, half a circle, and no signs of struggle and resistance in her hands and feet, then that is to say, she was killed by anesthesia or other drugs with weak hands and feet.

Bai Xin asked, "Is the blood test report out?" Are there any drug substance residues? Did the deceased take sleeping pills or anything like that? ”

Senior Brother Wang said, "No, the deceased's body is very clean, there is nothing. ”

"How is that possible?" Bai Xin said, "If she was killed by him, she would definitely struggle, but her body was so clean." ”

"We have also taken into account what you said. The investigators are still investigating, and we don't know exactly what happened, but the time of death has been determined again and again, and it was around 7 o'clock in the morning on May 28, and the time is correct. ”

"In other words, the posthumous message is a mystery?"

"Yes."

Bai Xin said: "Can you transfer me to the investigation team, I want to follow up on this incident." ”

"Then I'll help you go and talk to the leader, it's not a big problem." Senior Brother Wang patted his chest, and the packing ticket can be done.

"That's right, that's right!" Bai Xin's machine moved, and he said, "I understand! ”

"Got what?" Senior Brother Wang asked in surprise.

With an imperative smile on his face, Bai Xin said, "Think about it, how can a dead man speak? It's completely impossible, so that message must have been the work of the murderer! ”

Xiao Lin frowned, puzzled: "But the voice is indeed the deceased herself, and I have confirmed it with her relatives and friends." ”

"Still, sound can be made." Bai Xin said, "As long as you take some words from the previous recordings of the deceased and combine them into a sentence, won't you be able to explain the mystery of the message?" ”

Senior Brother Wang said, "Then how can we prove this kind of thing? This murderer is too good, isn't he? ”

"Is there a tape recording tape for the message? I took it to the sound appraisal department and asked about it, and I couldn't tell if I found it. Bai Xin took the tape from Senior Brother Wang, and ran to the sound department in a hurry.

She will definitely be able to break back a game, and this time she will definitely impress Su Mu.

Hey, she seems to be unconsciously competing with that man......

Bai Xin brought the tape to the relevant personnel, and then waited outside the door for the result.

About an hour later, a staff member called her in.

Chen Chen was also in charge of the sound review department, he took out the tape and asked Bai Xin: "Is this the case of the mint deceased?" ”

"Yes, is there a problem with the tape?"

"The sound of the tape does belong to the deceased, and I compared it with her previous recordings, and the frequencies are correct."

"It's not a problem," Bai Xin explained, "I know that of course it's her voice, and the murderer can't be that stupid." But I want to say that this recording must have been the murderer's interception of some single words from her previous recordings and synthesized into a sentence. Like, I eat, and I want to sleep. The word 'cut off me', and the word 'think' will become 'I think'. But this is indeed the voice that belongs to the dead. ”

Chen Chen was impatient and muttered, "Sister Bai Xin, you didn't understand what I meant. What I'm saying is that it's a coherent sentence spoken by the dead. ”

"What did you say?"

He turned the computer around, showed Bai Xin the sound wave display diagram on it, pointed to the places where the red and orange met, and said, "Look, the colors of this sentence are all right, and they form a coherent sentence." If it's a spliced single word, it will become like this, you see, like a dog gnawing, one up and one down. That is, this sentence was said by the deceased himself. ”

Bai Xin's mouth was slightly open, in disbelief.

That is, the person who died at seven o'clock really said this sentence at nine o'clock?

Leaving aside the question of time, even if the deceased recorded it to the murderer in advance, how could he deliberately leave such an excuse for the murderer to have time to escape and help the person who killed him escape?

Doesn't that make sense?

It's obviously a murder case!

Bai Xin was confused, she was confused, and after getting off work, she went back to the apartment.

At this time, she suddenly wanted to meet Su Mu, meet the omniscient man, and let him solve this riddle.

How can it be? How is that possible?

Is there really a mysterious posthumous post-death call in the world?

Bai Xin was in a daze and came to the door of Su Mu's house.

Before she could ring the doorbell, the other party learned about her deposit and opened the door in advance to greet her.

Bai Xin looked through the crack in the door, and suddenly attracted Su Mu's gaze.

Su Mu didn't explain so much, only said, "Come in." ”

Bai Xin nodded obediently and walked in, she asked, "Is there any mints?" I'm not going to throw up this time. ”

Su Mu was noncommittal, but still gave it to her.

She sat in her chair, clacking candy in her mouth.

Bai Xin's whole person is like a stray cat with hanging cat ears and squatting at the door of the house in frustration.

"That message is true, the person who died at seven o'clock, left a message at nine o'clock, I went to confirm the voice, it was not a single word spliced by the murderer, but a whole sentence said by the deceased himself." Bai Xin was stunned and continued: "How is it possible? Is there really an incident of posthumous messages? ”

"In 1969, there were rumors circulating in Denmark that he had left a message after his death. It is said that a driver who had been involved in an accident called his family within 10 minutes of his death, and the family picked up and heard a blind sound, but the call was from the deceased. In 2003, there were also rumors in Italy that a lady who had been murdered called the police within an hour of her death, explaining the characteristics and whereabouts of the murderer, and later allowed them to successfully arrest the suspect," Su Mu lowered his eyes and continued, "However, the reason why rumors are rumors is rumors means that there is no evidence and anyone can fabricate rumors, which is not enough to be believed." ”

"So what can we believe?" Bai Xin asked more seriously.

"Trust the evidence."

"What if the evidence shows that the posthumous message was deposited?"

Su Mu raised his head and glanced at her.

The corners of his mouth hooked a little arc, and said meaningfully: "Then it shows that the message after death is really zài." ”
