Jian Jing added two female characters to "Sleepwalking Girl", a female policewoman and a female prosecutor. But for dramatic conflict (actually intentional), she set them as sisters who don't get along with each other.

As for the emphasis on the case, she also has a different tendency this time.

The setting of "Devil Doctor" is originally fantasy, and it is not strict from the perspective of reasoning. "Rose Gold" focuses more on decryption, investigation, and adventure.

So this time in "Sleepwalking Girl", she plans to do some real reasoning, focusing on the case's tricks.

But to win with ingenuity, it is essential to polish the case itself. For most of July, Jian Jing was at home thinking about the content.

However, one afternoon, she suddenly received a call from Si Yingjie.

"Jingjing, are you home?" Si Yingjie's tone was unusually serious.

"Yes." Jian Jing was surprised, "Looking for me?"

Si Yingjie said, "I'm in trouble, you have to help me."

Jian Jing was immediately alert: "It's absolutely impossible to borrow me to get back at your girlfriend after she dumped you."

"No." Maybe the situation was really urgent, Si Yingjie didn't care about jokes, and said in a stern voice, "My sister's son was kidnapped, and the kidnappers didn't allow me to call the police, so I feel uneasy."

This scared Jian Jing, and she immediately said, "Come pick me up."

Si Yingjie: "I'll be at your house in ten minutes."

Jian Jing quickly packed up and sent a WeChat message to Kang Mucheng, asking him to help raise two dogs.

Just after she finished, Si Yingjie arrived with a fine.

Jian Jing followed him into the car and went straight to the point: "What happened?"

"This happened yesterday." Si Yingjie spoke quickly and hurried to explain from the beginning.

Si Yingjie's second sister married the son of a wealthy man. The couple was quite capable and took over the family business. They were also a wealthy family.

They had only one child, nicknamed Congcong. He was six years old this year and was still in kindergarten. He was picked up and dropped off by the driver and nanny every day. On weekends, the nanny would take him to the amusement park or park to play.

Yesterday, Saturday, Congcong was clamoring to go skateboarding - he was addicted to it recently - although Si's second sister did not approve of her son playing such a dangerous project, his father loved his son and secretly agreed.

The nanny had to take him to the skateboard park.

Of course, for the safety of the little ancestor, helmets and knee pads are all available. With a coach watching over her, the nanny was not worried.

But something went wrong. The nanny went to the bathroom, which took only ten minutes. When she came back, Congcong was gone, and the coach was nowhere to be seen either.

She thought the coach took Congcong to another place for training, but a few minutes later the coach came back and said that his girlfriend had just come to look for him and had been away for a few minutes.

At that time, the two had not yet realized the seriousness of the matter, because the skate park is not an open-air facility, but an indoor training hall, and outsiders cannot enter.

But then they searched several venues and couldn't find anyone, so they became anxious and hurried to check the surveillance.

The surveillance showed that a boy about 11 or 12 years old came to the venue with a skateboard, said a few words to Congcong, and then the two went out together.

Looking at the corridor surveillance again, the two children, one big and one small, walked to the door talking and laughing, then the boy turned back, and Congcong ran outside and got into a black car.

The nanny knew something was wrong and immediately notified the owner.

Congcong's parents wanted to call the police immediately, but then they received a call claiming that the child was in his hands and asked them not to call the police.

Si's second sister and Si's brother-in-law had a quarrel. The brother-in-law thought that they should call the police as soon as possible and ask the police to find their son. However, the second sister was afraid of angering the kidnappers, so she refused to call the police. Instead, she wanted to find an experienced professional to save people when they had a chance.

Si Yingjie has been in Heping City these two days. After hearing about his sister's troubles, he immediately thought of Jian Jing.

He advised his sister and brother-in-law: "The kidnappers must have been targeting Congcong for a while, and they must have a deep understanding of your family. Whether it's the police or the security company you mentioned, it's clear from their posture that they are not ordinary people, right? If the kidnappers sent someone to monitor, or there is a traitor in the family, it will be a disaster, right?"

Si's second sister hesitated: "The girl you mentioned is enough?"

"You don't think she looks like her, how can the kidnappers think she looks like her?" Si Yingjie argued, "I have seen her solve many cases with my own eyes. You don't believe her, but you don't believe me?"

Si's second sister knew her brother well, and knew that he was not a boastful person, so she finally nodded.

After hearing the whole story, Jian Jing asked, "Why did the boy ask Congcong to leave? Has he seen the kidnapper?"

"He said he was asked to go in and call someone, saying it was Congcong's aunt, who was bringing him some snacks." Si Yingjie answered.

Jian Jing nodded. Only a child would believe such a clearly problematic request, and it was precisely because the messenger was a half-grown child that the other people in the venue did not suspect anything.

"Is he a regular customer?"

Si Yingjie nodded, "My sister checked, he is the son of a small boss, and he has been learning skateboarding for several years."

Jian Jing asked again, "What did the kidnapper ask for?"

"Fifty million in cash," Si Yingjie said.

Jian Jing was confused: "How much is that? Can a truck load it?"

"About 750 kilograms," Si Yingjie said, "It's definitely not right."

Of course, a truck can hold 50 million, but who would run away with a truckload of cash? The kidnapper's request was completely unrealistic.

So why did he do this? One possibility is that he has never done this before and thought it was like a police and gangster movie, with tens of millions for just a suitcase. Another possibility is that this is just a test to test the obedience of his family members, and it will definitely be changed later.

Jian Jing tends to the latter.

"Let's take a look first," she said.

Arriving at Si's second sister's villa, Jian Jing met Si Yingjie's second sister. The siblings look very similar, but compared to the brother's casual and casual style, Si's second sister is a typical strong woman.

She got straight to the point: "Yingjie must have told you the whole story. What do you think now?"

"Do you have any guesses about the identity of the kidnappers?" Jian Jing asked without hesitation.

Si's second sister replied: "Either they are business competitors who want to retaliate against our family, or they have taken a fancy to our family because we have some money and want to make a fortune."

Jian Jing asked: "Do you have a specific name?"

Both husband and wife shook their heads.

"Have you checked the license plate number?"

Si's brother-in-law said, "I asked a friend to check it out. It's a fake license plate. The car turned into an uncontrolled road and never came out. I guess they changed cars."

Jian Jing thought for a moment and asked, "Based on your understanding, who could trick your child into following the other party without any doubt?"

The couple looked helpless at the same time.

The two looked at each other, and finally it was Si's second sister who answered: "A lot of people."

Jian Jing: "?"

They didn't know how to say it, but Si Yingjie didn't care and said directly: "My nephew has never gone out by himself, nor has he stayed at home by himself. He is usually accompanied by a driver and a nanny. Sometimes my sister and brother-in-law will send an assistant secretary to pick him up. He is not afraid of strangers."

Jian Jing sighed, and finally said: "Is the call recorded? Let me listen to it."

"It's recorded."

The recording was very short, only about ten seconds. The kidnapper used an electronic voice, speaking word by word with a weird tone: "Your son is in my hands. If you want to save his life, prepare 50 million in cash and don't call the police, otherwise you will never see your son again." Si

's second sister asked: "Who are you? Do you have any evidence to prove that my son is in your hands."

There was no answer on the other end of the phone and it was hung up directly.

Then, Si Erjie received a text message with a photo attached.

The photo showed Cong Cong, who was sleeping, wearing the clothes he wore when he went missing.

Si Erjie said, "I asked the nanny, the clothes were bought recently, and it was the first time she wore them, so the photo is real."

Jian Jing enlarged the picture and studied the details of the photo.

The child's clothes were incomprehensible, and there was very little background, only a sofa and a white wall, which were all common things, nothing special.

In this case, there was only one thing she could do.

"I want to talk to your nanny."

Brother-in-law Si was a little impatient: "Yingjie should have told you everything. Yingmei, I think we should call the police."

Second sister Si sneered: "Call the police? What if the kidnappers are angry and Congcong is hurt?" Then she turned to Jian Jing and said, "Ask if you want to. Let Yingjie take you there. No matter what, rescuing my son is the most important thing."

With the support of the hostess, Jian Jing's inquiry became smoother.

First, sort out the people around Congcong: a driver who is responsible for picking up the child, a nanny who is responsible for his food and daily life, and a tutor who is responsible for his enlightenment education.

Jian Jing asked the driver first.

He is the family driver, mainly responsible for picking up and dropping off the little master from school, picking up and dropping off the tutor to class, and sometimes when there are guests at home, he is also needed to pick them up. He is not just responsible for one person.

Jian Jing asked him, "Have you noticed that you're being followed recently?"

The driver thought carefully for a long time before saying, "It seems so. About half a month ago, I passed by a Volvo. I didn't pay attention to it at the time, but I seemed to have seen it twice later, so I have some impression."

"Do you remember the license plate?"

He shook his head and smiled bitterly, "Volvos are everywhere on the streets. If I hadn't scratched it that day, I wouldn't have taken it seriously if it looked familiar."

Jian Jing nodded, not embarrassed. Instead, he changed the subject and asked, "Is your work usually easy?"

"Fortunately, there's not much work, and the boss and the boss's wife are both quite generous." The driver's answer was flawless.

"What about your colleagues?"

"It's OK."

"How many years have you been doing this?"

"Sister Yuan (nanny) has been here for more than four years, Xiao Zeng (home tutor) has only been here for half a year, and I've been here for less than three years. I'm not familiar with the others, so I'm not sure."

"Do Nanny Yuan and Teacher Zeng get along well with the kids?"

The driver nodded.

After getting a rough idea, Jian Jing asked him about his schedule on the day of the kidnapping.

The driver said, "I dropped Sister Yuan and Cong Cong off and went back. The boss lady asked me to pick up Mr. Si. I dropped him off here, and when I went back to pick him up, I realized something had happened."

"I see." Jian Jing closed her notebook, "Thank you for your cooperation."

The second person was Teacher Zeng.

She was 26 years old, graduated from a prestigious school, and worked as a full-time private tutor for wealthy families. She was good-looking and well-spoken.

Jian Jing asked her the same questions as the driver.

Teacher Zeng said that she had only been working for half a year, but she got along well with the children.

"Congcong is very smart, but because his parents spoiled him too much, he is more self-centered and likes to play pranks." She commented frankly, "On my first day at work, he threw a bedbug into my cup. I asked him why he did that, and he suddenly started crying, which embarrassed me."

Jian Jing: "How is he now?"

"After I talked to his parents, they also understood my work. Recently, he has been much better, at least he won't tease the servants at home anymore."

Jian Jing raised her eyebrows: "He bullies the servants?"

Teacher Zeng was very reserved and indirectly admitted: "He was indeed naughty before."

Jian Jing asked her what she thought of this family.

Teacher Zeng said: "It's a typical kind father and strict mother family. The mother is strict, the child is most afraid of her and listens to her the most. The father loves the child more and thinks that as long as the child is healthy and happy, nothing else matters. Just teach him slowly."

"Does the child like the father more?" "

Of course, the father and son are very close."

Then asked her whereabouts on the day of the incident.

Teacher Zeng said: "My work is from Monday to Friday. I don't have classes on Saturdays and Sundays. I rest at home."

"Recently, have you been concerned about anything?"

Teacher Zeng thought about it and nodded slowly: "Yes."
