On the morning of May 14, 2018, the Municipal Public Security Bureau received a report that a man had died at home in a residential building in Xinhua Community, and the informant was an aunt who had come to clean up for the deceased. After forensic evidence and forensic identification at the scene, the case was a vicious homicide, and due to special suspicions at the scene, the case was handed over to a special case team led by Yang Wen, the former head of the Criminal Police Brigade of the Municipal Public Security Bureau, for investigation.

At night, the police station was dim, only the lights in the autopsy room were still on, Su Yang stood at the door of the autopsy room through the glass door, and could vaguely see a figure being busy.

Su Yang pushed the door in, and a tall man who looked to be at least 1.8 meters tall was wearing a white coat and a mask, looking intently at the corpse on the autopsy table in front of him.

"Hello, my name is Su Yang. Su Yang introduced himself, and without waiting for the other party to respond, he walked to the coroner's desk.

Su Yang looked at the male corpse lying on the coroner's table, his eyes were gloomy, and a knife cut with flesh in the heart of the corpse was shocking. He didn't expect that on the first day he entered the special case team, the victim he had to face turned out to be his senior Lu Ming at the University of Political Science and Law.

"You know each other?" the man asked suddenly.

Su Yang nodded 'En', and his tone was gloomy.

"Hello, my name is Jiang Xu, you can call me a bug, they all call me that. Jiang Xu briefly introduced himself, and then fell silent again.

He leaned down and touched the corpse's head with his hands, then examined his eyes, nose, and mouth, and touched them one by one along the location of the corpse's organs, and then frowned.

He stretched out two slender fingers, gestured back and forth at the knife edge of the corpse's heart, and then took out a ruler, and then he turned the corpse over, the corpse's solid back exposed to the air, and a slender knife edge appeared behind the back corresponding to the heart.

Su Yang didn't dare to disturb him, so he could only watch silently.

What made him a little concerned was that Jiang Xu did not wear gloves during the autopsy.

Jiang Xu dissected the corpse and took out the heart from it, he looked at the heart in a daze, Su Yang saw the wound in the heart, and almost vomited, and when he finally let his stomach come over, he found that Jiang Xu was frowning at the heart in a daze.

Jiang Xu's eyes were cold and deep, as if he was looking at something that disgusted him extremely much.

Looking at the heart in his hand, Jiang Xu's thoughts were pulled back to many years ago, when he first became a forensic doctor, his teacher was worried about his work and took the initiative to ask for help, but the next morning after the autopsy, when Jiang Xu walked into the autopsy room, he found that the heart where the fatal wound of the corpse was located was missing, not only that, but his teacher also disappeared suddenly, and there has been no news since then.

Su Yang saw that Jiang Xu had not reacted, and couldn't help but speak: "Ahem, bug, that ......"

Before he finished speaking, he was stopped by Jiang Xu: "Don't speak!"

Su Yang immediately shut up and didn't dare to speak out again.

After a long time, Jiang Xu came back to his senses and continued the work at hand, and it was not until it was all over that he regained his calm tone.

"I'm sorry just now, I thought of some old things!"

Su Yang shook his head and asked him not to care, but he really felt that this forensic doctor was too strange.

Nearly an hour later, Su Yang handed the autopsy report to Su Yang's hand, and then said coldly.

"The heart penetrates the wound, the murderer stabbed very deeply, the blade of the knife is connected to a part of the handle and goes straight to the bottom of the heart, the width of the knife surface is nearly 5cm, and the length will not exceed 25cm, it can be seen that it is ......"

Jiang Xu paused, as if he was observing Su Yang's expression, a little hesitant.

"The murderer hated him very much, and in order to ensure that the knife could completely penetrate the heart, the murderer used so much force that even the handle of the knife was sunk in, so there was a situation where the wound in front of the corpse was thicker and uneven, while the wound in the back was thinner and smoother. Jiang Xu's tone was calm and methodical, as if he was endorsing.

Su Yang nodded, and glanced at the corpse again, he hadn't been to the scene yet, and from Jiang Xu's report alone, he couldn't confirm more clues.

"Do you drink coffee?" Jiang Xu suddenly asked softly.

Su Yang was a little stunned, and then nodded.

Jiang Xu smiled, then covered the body with a white cloth and beckoned Su Yang to go back to the office with him.

Su Yang followed Jiang Xu back to his office, Jiang Xu took off his white coat, threw the mask in the trash, and then turned around and walked towards the sink.

Su Yang looked at him and felt relieved, he was really afraid that Jiang Xu would make him coffee directly after the autopsy without gloves, and he wouldn't dare to drink it.

Su Yang looked around and was surprised to find that this office was unimaginably simple, and it didn't look like an office that a busy man should have.

Jiang Xu took out a cherry-sized pill from the box of the sink, then crushed it in his hand, rubbed it vigorously, and soon saw that his hands were covered with powder, Su Yang looked at his hands, and the powder was gradually turning black.

Su Yang walked over incredulously, Jiang Xu felt his approach and smiled at him.

"This is my homemade handwashing pill, which can be used to expel and decompose cadaveric toxins and infectious cells and tissues from the pores of my hands. ”

As he spoke, he rinsed the powder off his hands, then took a clean towel and dried his hands.

Turning around, Jiang Xu walked to the other table and fiddled with the coffee machine on the table.

Su Yang also thought that the people in the police station should drink instant coffee, because it is simple to brew and saves time.

Jiang Xu walked to the coffee machine and found that the jar on the coffee machine where the coffee beans were placed was empty. Jiang Xu turned around, walked to his locker, and opened the door.

The cabinet that was supposed to be full of materials was filled with bags of coffee beans.

Jiang Xu took out a bag, closed the cabinet door, then opened the bag, walked back to the coffee machine, and poured the coffee beans into the container.

After a while, the sound of things crumbling came from the coffee machine, but the sound was not loud, and soon the office was filled with a strong aroma of coffee.

Jiang Xu walked up to Su Yang with two cups of coffee and handed one of them to him.

Su Yang was a little hesitant to take the coffee, he didn't like black coffee, usually he would buy instant coffee with a strong milky flavor or sweetness.

Jiang Xu laughed when he saw Su Yang's expression.

"Drink and see, let it go!"

Su Yang looked at Jiang Xu in surprise, he actually guessed his idea again.

Su Yang frowned and took a sip of coffee, to his surprise, although the coffee was very sweet, it did not affect the lubricating taste, although Su Yang did not know how to taste coffee, but he could drink the obvious difference between Jiang Xu's coffee and instant coffee.

"You should have a question for me!" Jiang Xu saw that Su Yang seemed to be very satisfied with his coffee, and his mood inexplicably improved.

Su Yang and Jiang Xu had only known each other for less than two hours, but Jiang Xu was like a roundworm in his stomach, constantly dissecting his psychology.

Su Yang was stunned, not knowing how to answer.

"It's okay, you're friends after drinking my coffee, just ask if you have any questions!" After speaking, Jiang Xu quietly waited for Su Yang to speak.

Su Yang came back to his senses, and somehow, Jiang Xu's words actually made him feel at ease.

"That, why are you called a bug?" That's right, the first question Su Yang wanted to ask was this, in fact, he wanted to ask at the time, but because he was not familiar with Jiang Xu, he kept holding back.

"Hahaha. Jiang Xu suddenly laughed, although he guessed that Su Yang must have a question to ask him, but he didn't expect that the first question he wanted to ask turned out to be his nickname.

"Because I was afraid of bugs, I let them call me bugs. Jiang Xu looked directly at Su Yang and said with a smile.

Su Yang was puzzled and looked at Jiang Xu with a frown.

Jiang Xu put down the coffee cup that had bottomed out, still with a smile on his face.

"Human beings instinctively run away from the fear in their hearts, but they never think that only by facing it can they eliminate the fear. Jiang Xu said as he walked to the coffee machine, picked up a clean cup, and brought himself a new cup of coffee.

Su Yang felt that Jiang Xu was a little strange.

"You must think I'm weird!"

Su Yang didn't speak, just looked at Jiang Xu's back, and was no longer surprised that Jiang Xu had guessed his mind again and again.

"I have a cleanliness fetish, slightly. Jiang Xu said lightly.

Su Yang remembered Jiang Xu's autopsy, and his face wrinkled.

Jiang Xu always had a smile on his face.

"Bodies are the cleanest thing in the world to me, and no matter what they did in their lifetime, as long as they lie on my coroner's table, to me, they are the cleanest. They don't lie and always answer the questions I ask honestly. ”

Su Yang listened carefully to every word Jiang Xu said, and couldn't help but feel a chill down his spine.

Jiang Xu's cleanliness is a kind of spiritual cleanliness, and what he feels clean spiritually is, even if others feel dirty, he also feels clean.

"Probably...... The murderer is just like me. Jiang Xu raised his head, looked out the window faintly and said.

"The same?" Su Yang was taken aback and asked rhetorically.

"I mean, the murderer may have had a cleanliness fetish. ”

"Why do you say that?" Su Yang continued to ask, puzzled.

"The scene was very clean, there was no blood in the cracks of the floor tiles, and not only that, but the body was cleaned by the murderer, which shows that the murderer may have spent more time and energy dealing with the scene than he killed. Jiang Xu's tone was calm, and he turned to look at Su Yang seriously.

Seeing Jiang Xu's expression, Su Yang also became serious.

"In other words, for the murderer, it may be more important to dispose of the scene and the body than the murder itself?" asked Su Yang.

Jiang Xu shook his head.

"I can't say that, it should be that the murderer found that the blood stains caused the scene to be very dirty after killing people, and out of instinct, he carefully handled the scene. ”

Jiang Xu paused and continued.

This is a kind of obsessive-compulsive disorder, ordinary murderers will not be so careful even if they clean up the scene, which means that when the murderer cleaned up the scene, he repeatedly checked it to make it possible to do it without leaving any traces of blood in the details that are extremely difficult to find. ”

Su Yang clasped his hands in front of his chest, pressed his hand against his chin, and looked at the lines on the ground.

"Could it be that the murderer's information was left at the scene, such as footprints, fingerprints, etc. That's why the murderer handled the scene so carefully?"

Jiang Xu didn't answer and left the office, Su Yang didn't know where he was going, so he didn't follow, and soon Jiang Xu returned to the office with a stack of photos in his hand.

"Here are the photos of the scene I'm coming to. Jiang Xu put the photo on the table.

Su Yang spread out the photo and looked at it carefully.

In the photo, I clearly saw the environment of the scene, an ordinary house, the body fell on the ground next to the sofa in the living room, the ground was very clean, what caught Su Yang's attention was that there were no traces of being cut by a knife on the deceased's clothes, and there was only a small amount of blood stains that could barely be seen.

Su Yang frowned slightly and picked up the photo.

Jiang Xu seemed to have guessed that he would pay attention to the photo, and took out another photo from the pile of photos and handed it to Su Yang.

Su Yang took the photo and suddenly realized.

"The murderer not only handled the scene, but also changed the clothes of the deceased?"

Jiang Xu handed him a photo of a bloody shirt placed in the washing machine, and it was enough to see from the photo that blood stains were all over the clothes.

Jiang Xu nodded in affirmation.

"The time of the murder was the day before yesterday, that is, on Wednesday evening, between 5 and 8 o'clock, and the nature of the murderer's work should be 9 to 5 or a shift system, and I personally prefer a shift system. Jiang Xu said.

Su Yang also agreed with Jiang Xu's statement that if the murderer was working from 9 to 5, then the preparation time for committing the crime seemed a little tight.

Jiang Xu stared at those photos, his eyes rolled back and forth flexibly, and he sighed for a while.

"I'll have to go to the site again during the day. ”

Su Yang said 'en', it just so happened that he hadn't been to the scene yet, he felt that Jiang Xu would tell him because Jiang Xu wanted him to go with him.

Outside the window, there was already a little light, and before I knew it, it was already more than 4 o'clock in the morning, Jiang Xu tidied up the photos, and then pointed to the recliner on the side.

"You can sleep here for a while, and I'll go to the dissection room and rest. After speaking, Jiang Xu was about to leave the office.

"Wait, there's a ...... in the dissection room Corpse. Su Yang's voice was very small and trembling a little.

Jiang Xu smiled and didn't turn around.

"Well, I usually rest there, and the smell of the dissection room makes me feel at ease. After speaking, Jiang Xu walked out of the office.

Su Yang looked at Jiang Xu's back and couldn't help but shudder, this was the first time that he had a sincere admiration for a person in his heart.
