Hongjing is an old town

There are streets that are not long or short, rivers that are not deep or shallow, and schools that are not big or small.

Shi Yàn Primary School is located on a hill in the northwest corner of Hongjing City, surrounded by dense woods for most of the schools, where Lin Chen works as an ordinary dormitory manager.

Dormitory management is almost one of the easiest jobs in the city, you only need to check whether the children are there at night, check the dormitory from time to time, prevent the children from hiding dangerous items, and then there seems to be nothing else to do, of course, seven or eight-year-old primary school students, can hold dangerous goods, at most slingshots, pencil sharpeners and the like, so the daily work of the dormitory manager is as idle as a basin of water.

Therefore, when Lin Chen received a phone call asking him to bring money and go to No. 6 Yanjia Lane to ransom people, he only hesitated for a moment whether he should call the police, then took his wallet and went out by bus.

The kidnappers had a good day, the trees were very green and the flowers were red, and even the river under the Cangshui Bridge was as bright as freshly wiped glass.

As if he was being located, as soon as Lin Chen crossed the bridge, the mobile phone rang again, and the kidnapper's voice was hoarse and calm: "Mr. Lin, please turn left, I will wait for you inside the sixth door." ”

Before Lin Chen could start thinking about the cold joke about the six doors, he had already arrived at the designated position.

The wooden door creaked open, and he looked up to see a bearded man standing in the doorframe.

The man propped up the doorframe, a cigarette in his left hand, his sleepy eyes, his eyes vaguely green, his eye sockets were deep, and although most of his face was covered by beard, he could still make out the knife-like outline and the excessively white skin.

Lin Chen was swept from head to toe by the other party unscrupulously many times, and still spoke good-naturedly: "I'm here to pick up the little ghost in your house and go back, thank you for taking him in."

After he finished speaking, he saw the man slowly raise his hand, put his thumb, index finger and middle finger together, and even rubbed it gently.

This is an obvious act of begging for money, but in this bearded man, although he is a scoundrel to the extreme, he is also extremely handsome.

Lin Chen put his hand into the pocket of his cargo pants and took out a dark purple bill with a missing corner: "It's exactly five yuan." ”

The man took the money and put it in his trouser pocket again, not ashamed, he raised his hand to take a puff of cigarette, and then moved to the side, but his hand was still on the door frame.

Lin Chen bowed slightly in thanks, squeezed under the man's arm, squeezed inside, and walked inside.

On the plank bed on the side of the river, he saw a pouting little buttocks.

"Skipping school is not a good thing." Lin Chen sat down on the edge of the bed, reached out and fished out the little fat man with the ostrich, put the person on the bed and straightened it up, then bent down, picked up the shoes on the ground, and put them on the little fat man's feet.

"If it's a man, it's understandable to make a mistake once in a while." "But the problem is, first of all, I don't like to go out, and secondly, I'm really poor......," he said, patiently tying his shoelaces, and continued, "So, sneaking away is a more appropriate way to deal with it than to call me." ”

His voice was very soft, and the little fat man looked at the bearded man at the door, with a sobbing expression.

Lin Chen glanced at the little fat man, and then at the man who seemed to be smiling, as if he suddenly realized something, he took the little fat man's hand, turned around and wanted to leave.

The moment he passed by, he felt a chill on his wrist, and a pair of silver shackles were just on his wrist.

Lin Chen looked at the little fat man and said helplessly: "However, if you provoke the police, don't slip away, it would be more appropriate to be coquettish and cute and hug your thighs." ”

When the bearded policeman on the side heard this, he spoke slowly: "Mr. Lin is really a wonderful person, how about going to have a cup of tea together?" ”

"I'm not a good fit to go to the police." Lin Chen thought about it seriously, and then replied like this.

The man took a drag on his cigarette and laughed.

―――

If you can solve the problem by being coquettish and cute, don't go to the police station, because the interrogation room here is always very gloomy and depressing.

There will be iron bars on the windows, facing the wall of you, and there will be big words such as leniency in confession and strictness in resistance, and you will face the awe-inspiring police, and at the same time, you may be secretly watched.

Zhang Xiaolong stood outside the one-way glass, monitoring the suspect's every move in the interrogation room. From time to time, she bowed her head and recorded something in her notebook, striving to make a good impression on the new leader. Perhaps it was because she was too serious, and it wasn't until a low, hoarse voice came that she realized that there were two people around her at some point.

"How's it going?"

Looking at the side face of the new captain, Zhang Xiaolong's face turned very red, but as a strictly trained police academy student, she quickly adjusted her mentality and reported: "He has been sitting for an hour and thirteen minutes, just looking at the photo!" Zhang Xiaolong hurriedly looked at the table below, and flipped through two more pages of notes, "According to your request, no one talked to him, and someone went in to deliver water half an hour ago, but he didn't drink it." Oh, the photo he saw the most was the third one, it's really weird, Captain, there must be something wrong with this guy! ”

The little girl pressed the ballpoint pen twice, looked at the interrogation room, and said with some excitement.

In the interrogation room, a young man in a white shirt sit.

The young man's hair is very dark, his eyes are even darker, he is a little thin, and his figure is not tall, but maybe it is the calm face or maybe the serious eyes, which make him look solemn and stable, like the pine in the mountains or the bamboo by the lake, when the wind blows, there is a very clean atmosphere.

And on the wooden table in front of him, there were three photographs.

In the first photo, there is a serene old man lying on the bed, wearing a royal blue shroud, looking as if he had just fallen asleep.

The second photo shows the morgue where the old man is lying, as there is also a body with a white sheet next to the old man.

If the first two photos are a bit cold, the third one looks weird.

The old man who was lying flat in the morgue appeared in a shop, the old man had his eyes closed, wearing an old navy blue uniform, he was lying on the ground, there was a little blood around him, if you look closely at the photo, you will find that the old man's pocket on one side, there is white sand flowing all over the ground.

"Lin Chen, where are you between 1 and 3 p.m. on September 7?"

The door was pushed open and closed, and the policewoman was on the wooden bench, her voice crisp, interrupting Lin Chen's deep thought.

"In the city's small dormitory management station." Lin Chen replied unhurriedly, he looked at the photo again, and then raised his head.

The policewoman in front of him was very beautiful, with long black hair and white earlobes, and in the ears of the policewoman, a small wireless headset was stuffed.

"Can anyone testify?" The policewoman hurriedly interrupted him and continued, "You said you were in the dormitory station, who can testify?" ”

"At the time you said, I was alone in the dormitory station, and the students were all in class, and there was really no one to testify."

The suspect answered neatly, Zhang Xiaolong was a little depressed, she pressed the pen and continued to ask according to the questions in the notebook: "Then, you haven't been to the Third Hospital recently?" ”

"Sue me, why did you arrest me?" Lin Chen asked.

The policewoman's eyes wandered, and she subconsciously looked at the glass wall on the side of the interrogation room.

Lin Chen leaned forward, as if he suddenly understood something: "I heard that recently in the morgue of the Third Hospital, there will always be a neatly dressed male corpse, and there will always be a handful of white sand next to the corpse. He stared at the policewoman's eyes, then leaned back in the chair, and knew in his heart: "This thing is extremely strange, if the city bureau finds it tricky, it will probably ask for help from two kinds of people - one is a Taoist priest, the other is a psychologist......" He didn't give the other party time to argue, and suddenly asked: "So, your cooperative unit is H University, right?" ”

Zhang Xiaolong's eyes widened, staring at Lin Chen as if she was perverted, and suddenly, she pressed the headset, as if she had received some instructions from it, she stood up suddenly, turned around and left.

Lin Chen turned sideways, aimed at the one-way glass, and said lightly: "Come out, don't hide." ”

Moments later, the door to the interrogation room was opened again.

A slightly chubby man pushed the door in, he was holding a hot water bottle in his left hand and a freshly washed porcelain cup in his right hand, he put the cup on the table, took out a paper bag of tea from his pocket and poured it into the cup, and then quickly poured in the hot water. After doing this, he bent down and put the teacup in front of the suspect very respectfully, his voice trembling a little: "Master...... Senior Brother ......"

"It turned out to be Professor Fu." Lin Chen didn't take the teacup, and his tone was a little cold.

As the only criminal psychology expert hired by the city bureau, Fu Hao rarely has a helpless time in the police station.

"Senior brother...... I didn't catch you! "He was about to cry.

"Why did you arrest me?" Lin Chen asked crisply.

"It's a handful of sand."

"What kind of physical evidence is this?"

"Senior brother, I don't dare to deceive you." Fu Hao leaned forward, a little dogleggy: "Recently, there has been a lot of panic in the city hospital, there will be a dead body in the morgue every once in a while, the corpses are all neatly dressed, and the corners of the bed are always sprinkled with fine sand, you know this." ”

Lin Chen nodded.

"This morning, the captain of the criminal police team met a lost child on the side of the road, the child opened the car window, took out a handful of sand from his pocket, and said Uncle, I want to eat KFC, can I exchange this with you?"

"Genius." Lin Chen could hardly believe his ears.

"Hey, hey." Fu Hao said with a smile: "Then, after comparing the physical evidence department, the sand taken out by the child should be the same as the one next to the corpse." ”

"What a coincidence." Lin Chen frowned

"It's just a coincidence, senior brother, do you know, just yesterday, there was a riot on Chunshui Street, an old man fell to the ground in full view, and when the ambulance arrived, he said that the old man had been dead for at least several hours." Fu Hao lowered his voice and said word by word, "Moreover, a handful of sand fell out of the old man's pocket. ”

"What kind of sand is it?"

"It's a very special sand, very white, but the physical evidence hasn't been figured out yet."

After hearing this, Lin Chen frowned: "Take it for me to see." ”

Before he could finish speaking, the door of the interrogation room was pushed open again, and a bearded man walked in with a bag of evidence.

"Mr. Lin, the contemptible surname is punished, and the punishment is from the company." The man had changed into a police uniform at some point, his demeanor was dignified, and his attitude was excellent, just like the hooligan who rubbed his fingers before, "I hope you can recognize it, have you ever seen this kind of sand?" ”

Lin Chen didn't bother to look at him, he just picked up the bag of sand on the table.

Weighing about 50 grams, he glanced at the bearded man, then pulled open the bag and carefully twisted it a little.

The sand is very white and the grains are very clean, which is clearly different from the rough stones on the construction site or the fine sand on the beach.

Lin Chen put the white sand back in the bag, he looked at Fu Hao, and his tone was cold: "You haven't seen this sand?" ”

"I don't think so." Fu Hao replied honestly.

"I don't know you here, how did you graduate?" Lin Chen asked seriously.
