In Sham Shui Po that night, there was an area where there were more plainclothes officers than civilians.

They searched everywhere for units that did not have anti-theft windows installed, knocked on doors and asked if there were any suspicious people wandering around, and asked the residents to pay attention to safety.

For those families who were restaurants or mobile stalls selling things, and whose social connections were not close, and who would not be discovered immediately even if they were killed, plainclothes officers would lurk nearby and secretly follow them.

The distance between people in the city seemed to be closer, but on the contrary, if a neighbor's family passed away, if no company came to the door to say that the employees had been absent from work for many days, the neighbors might not find that the family was wiped out instead of returning to their hometown.

The distance between everyone's hearts has become farther, and they don't understand each other that well, so there is no protection function.

The city, as a new walled city, can protect against wild beasts, but it cannot protect against its own kind.

The once bustling streets of Sham Shui Po are now unusually deserted. Everyone goes home early, fearing that they might run into a murderer on the street.

Although they like to watch the hustle and bustle, it is unlucky and they still have to hide.

Some families that can afford it simply move in together after discussion. On this night when the police are encircling the murderer, they arrange a duty roster to take turns to keep watch to ensure that they can spend the night in absolute peace.

Jiayi also called her eldest brother and Sun Xin. Sun Xin immediately took his roommates Clara and Ah Xiang to the Yi family. Jiayi would not go home today, so Ah Xiang and Clara could share her bed with her, while Sun Xin would sleep in the study.

The two men decided to keep watch separately, Yi Jiadong in the first half of the night and Sun Xin in the second half, to ensure the safety of everyone in the house.

After hanging up the phone, Jiayi sat back at her desk, frowning, and kept looking through the resident information in front of her.

These files recorded the resident's home phone number, the number of residents in a unit and their family status, the couple's work situation, whether they were tenants or landlords, the situation of their children, and other information.

There seemed to be a voice in her head reminding her that there was something useful in this information, but she just couldn't sort out her thoughts and couldn't find this inspiration.

She scratched her head in annoyance, and the sense of responsibility turned into pressure at this moment, making her uncontrollable panic.

Looking up, the clock hands pointed to 8:38. The murderer usually committed the crime at 2 or 3 in the morning. If the murderer committed the crime today, there were only about 6 hours left. In

such a large area, with countless communities and countless residents, could the police really find the murderer before 2 a.m.?

Moreover, Wang Sir was still struggling. If they continued the search late at night, they might be reported for harassment.

Maybe not only will they not be able to catch the murderer, but they will also be reprimanded by their superiors. The anger of the citizens may eventually turn to the police...

Jiayi wiped her face vigorously, stood up and paced around the conference table. Her brain was still thinking rapidly, recalling all the contents mentioned in today's meeting, including the flow images...

After an unknown amount of time, Jiayi suddenly tilted her head and quickly wrote in the notebook: What if the murderer didn't go through the window, but still went through the door?

After thinking quietly for more than ten minutes, Jiayi, who had been motionless all the time, suddenly raised her head and shook her eyes slightly, obviously thinking at a high speed.

Fang Zhenyue looked up at her, but didn't dare to disturb her.

Jiayi recalled that she had tried to rent a house to live alone when she was in college, but because of her limited budget, she could only rent a fake single-family house divided into three households, and it was on the lower floors.

Because she lived so close to strangers, most of the tenants nearby were migrant workers with a high turnover rate. There was even a young man who seemed to never comb his hair living next door to her. He always had a dazed look and looked half asleep, which often made her feel uneasy.

At that time, every night after school, she was worried that when she was not at home, bad guys would sneak into the house, hide in the closet or under the bed like in the movies, and kill her or rape her while she was sleeping. So she always checked all the closets and under the bed and other places where people could hide, and then locked the door to feel at ease...

Taking a deep breath, Jiayi's eyes froze and looked at Fang Zhenyue:

"Brother Yue, is it possible that the murderer sneaked into the victim's home during the day when the victim was not at home, hid under the bed or in the closet, and waited for the victim to fall asleep before coming out to commit the crime?"

If so, even if the victim had anti-theft windows at home and put a refrigerator in front of the door before going to bed, wouldn't it be useless?

Fang Zhenyue took a deep breath and stood up suddenly.

"We can't search every house..." Do we have to scan fingerprints not only on the windows of houses without anti-theft windows, but also on the doors of all houses nearby?

"Can we broadcast through a loud speaker across the street? Just keep reading [The murderer may be hiding in the closets and beds of citizens, waiting for you to fall asleep to attack. Citizens are requested to take weapons and cautiously check closets and other places where people can hide.] Also, read [Residents who do not have anti-theft windows at home, please check if there are any murderers sneaking in, make defensive arrangements at the windows, and place more equipment to prevent the murderer from sneaking in], will that work?" Jiayi raised her eyebrows and suggested.

"Just knock on the doors of every house." Fang Zhenyue pondered for a while and made a decisive decision.

"Then... suppose... the murderer has found his target. Didn't we think of the family as a freelancer, opening a restaurant, a mobile commerce, etc.? At the same time, there is another condition to be met, that is, no one is at home during the day, so that the murderer has an opportunity to take advantage of it." Jiayi slapped the several piles of documents in front of her.

"The murderer may not care about the target he had chosen before, or even the screening target when he was besieged. He really needs a temporary hiding place--" Fang Zhenyue thought about it, and decided to respect Jiayi's consideration, "Then we will give priority to the target family that was previously profiled."

"Okay! Thank you, Brother Yue." Jiayi said gratefully.

Fang Zhenyue patted Jiayi, turned around and left the office.

Now all the detectives of Group B have been sent out to carry out the search mission, and all the people who can be mobilized in the police force have been mobilized. He simply called Sister Yin and called back all the clerical staff to work overtime, and all those from other departments who were not participating in the search mission tonight came to help with the screening.

Half an hour later, the office of Group B was full of people. Sister Yin led everyone to sort through several files and documents, and prioritized the families with loose social connections who might die at home and no one would find them for about a week. The addresses, phone numbers and other information were extracted and handed over to Sister Yin for integration.

Fang Zhenyue took Jiayi out with them, and took the list of 10 households they had screened out before waiting for Sister Yin to arrive, and went to visit these households first.

After visiting these households, I will call Sister Yan, who will give the latest list she compiled to Fang Zhenyue and Jiayi, and the two will continue to do the investigation according to the list, and so on.

The night in the city is warmer than the night in Tai Po. Even if there is wind, it is not cold. But Jiayi still tightened her collar when she got off Brother Yue's jeep.

Fang Zhenyue called Wang Jiewang to tell him about his and Jiayi's new things. Sir Wang immediately pointed out the rashness of this action.

But Fang Zhenyue was ready. Even if someone complained about harassment tomorrow, it would be better to be scolded by Sir Huang than to have another family killed.

"I will mobilize a team from the mobile force to cooperate with us in the investigation." After Fang Zhenyue hung up Wang Jiewang's phone, he dialed again.

While waiting for the other party to get through, Jiayi crossed her arms, turned her head, and said with her face raised:

"Come on, Brother Yue! If there is a complaint, I will share the responsibility with you!"

Her eyes were firm and her sword-like eyebrows were raised.

A car drove across the street, illuminating the round clock hanging next to a store on the corner in the distance. The time showed 21:40.

…

…

In order to avoid being complained about tomorrow, Jiayi bought a lot of fried taro sticks when she passed by a fried taro stick stall, carrying a bag of many portions.

When she passed by a mobile stall selling fried nuts, she bought a lot of fried nuts.

Every time she knocked on a door, Jiayi would give the fried taro sticks or fried nuts to the other party. After gaining the other party's understanding and goodwill, she would then proceed to the official stage: asking about the family's situation and confirming that they had taken anti-theft and anti-break-in measures every night. Then, she would ask the residents to check all the places in their homes where people could hide.

If the residents do not want to let the strange police enter the house, they can take the dagger and self-defense tools and do the inspection themselves. First, they must ensure that the murderer will not suddenly appear from somewhere to take hostages, and second, they must ensure that there are no people hiding in any area of ​​the house.

After completing these inspections, Jiayi will politely say goodbye to the residents and say a few auspicious words to wish them well.

During the whole process, Fang Zhenyue stood behind Jiayi like a demon.

Therefore, although some residents feel that it is annoying to be knocked on the door in the middle of the night and asked for this and that, and are very reluctant to cooperate with the police inspection, firstly, no one dares to reach out and hit the smiling man, and secondly, seeing the knife-faced evil star behind the smiling man, even if they feel like hitting the smiling man, they are more or less afraid. Therefore, they

ran to several houses without any conflict with any citizens.

However... the murderer has not been caught yet.

When the clock pointed to 22:30, Jiayi began to feel anxious.

"Brother Yue, did I guess wrong?" Jiayi held the list in her hand, looked down at the names of residents that had been crossed out, and the remaining residents that had not been visited. She couldn't help but turn around and ask Fang Zhenyue anxiously.

This time it was all her guess. Without the backing of the mind flow image, could it be completely wrong?

When she thought about the fact that she had taken the wrong road and failed to really guess the murderer's choice, if someone was really killed tonight... she felt her fingers trembling.

That was something she absolutely didn't want to see.

Fang Zhenyue turned his head to look at her, and the female inspector's face looked a little gloomy under the moonlight.

He reached out and touched the back of her head. "That's what investigating a case is like. It's sometimes boring. Even if we are full of passion, we may be exhausted. Don't lose heart... do your best and leave the rest to fate."

He raised his head, looked around at the building numbers, and pointed to a certain place. "That's it." As soon as he finished

speaking, he strode towards the building.

Jiayi followed the back of Brother Yue. The tall and strong inspector had an upright posture. His walking style was in line with the idioms that describe a person with a majestic figure: holding his head high and walking with broad steps, walking like a dragon or a tiger...

In short, he was very decisive and neat.

He was determined and did not hesitate.

Jiayi felt the "qi" and was encouraged, so she also raised her head and followed with big steps.

He continued to do his best without distraction.

……

……

Since there are fewer people strolling around Sham Shui Po tonight, the young couple selling fried taro balls have finished work early.

Tonight, they can go home and take a good bath, and sit on the sofa with their family to watch TVB's evening programs. It is a rare leisure time.

Because the husband has a flat back of the head and is very hardworking, the children who grew up with him call him "Bian Tou Tuo", which means an ascetic monk with a flat head. This nickname has been used for more than 20 years. Now that they are married, even his wife is called "Bian Tou Po".

As soon as the flat-headed couple got home, they washed off their grease one after another. Bian Tou Tuo helped his wife blow dry her hair, and then went to blow dry his daughter's hair.

The flat-headed woman went to boil eggs, and then the family of three sat on the sofa watching a show, laughing and eating peeled white eggs. They were fragrant, hot and tender. Although this late-night snack was not luxurious, it still brought them a full sense of happiness.

The little daughter was very excited after taking a bath, didn't want to sleep, and couldn't watch the programs watched by adults, so she ran around the house holding eggs to consume energy.

When she returned to the small bedroom, she jumped on the bed, jumping up and down on the soft quilt with her bare feet.

The egg yolk accidentally fell on the quilt, and she threw it down again, sticking her butt out and carefully twisting the egg yolk on the quilt. When the egg yolk was twisted, it all stuck to her fingertips. She simply sat cross-legged at the foot of the bed and twisted the egg yolk on her fingers.

The eyes randomly fell on a certain place, but suddenly stopped.

The closet was tightly closed and seemed to be flawless, but a ribbon fell from above the dirty clothes that mom and dad had casually piled on the floor yesterday.

If you were not a member of this family, you might not think it was strange. This family simply did not have the time and energy to tidy up the house, or the head of the family just had the habit of throwing clothes away casually. It was not normal to have dirty clothes and ribbons.

But the little girl recognized it at a glance. It was the belt of her only little princess dress. Mom always hung the dress and the belt together at the far left of the closet.

She could only wear that dress on weekends or holidays... But how could its belt be thrown together with mom and dad's dirty clothes? She obviously didn't wear that skirt yesterday.

After swallowing the remaining eggs, the little girl jumped off the bed, her cheeks puffed up, her face raised, her feet raised, her arms stretched out, and she grabbed the closet door defenselessly...
