Zhu Chuchu's home is very dark, and the white sofa has been sitting for a long time, showing many traces of black ash that cannot be washed.

As she spoke, the room was filled with the constant sound of wheelchairs sliding on the floor.

It's a lifeless home, and everything seems to be stuck in the nineties, with an old hot water bottle, a clockwork frog on the windowsill, and a red and white enamel basin......

Mo Kexin was almost breathless, she wanted to ask about Zhou Zhou Liu, but the old lady in front of her looked like she was dead, and her soul was floating weakly.

The line between the dead and the living is not so stark here.

Li Nan said: "It's been several years, do you remember it so clearly? ”

"Right...... I have cooperated with the police many times in investigations, so I remember that time very well. ”

"Did the police tell you some clues about the scene?"

"Nope."

Li Nan nodded, her expression did not change: "Thank you, maybe we will come to disturb you a few more times." ”

As soon as he went out, he couldn't help but pull Li Nan: "Do you think what she said is the truth or a lie?" If it's true, then how can we help her clarify? ”

"I'm a polygrapher, not an immortal. But as a rule, she is neither telling the truth nor telling a lie, and people often mix truth and falsehood in their narratives. Honesty is far more difficult than one might think. ”

Li Nan said lightly: "If you want to live your life, people will even deceive themselves." But one thing is obvious, her description of entering the house and seeing the deceased collapsed in the doorway does not match the facts, the place where the deceased died was in the living room. ”

While talking, the two of them had unconsciously walked to the seafood factory park.

"I found the news on the Internet, and it is true that there have been several rounds of layoffs here, and the business here has not been good for 13 years."

Mo Ke followed behind Li Nan curiously, who seemed to be circling in this area.

"Are you thinking about what she just said......" Mo Ke's heart spun around and suddenly "eh", she hurried to the door to a few trees, these plane trees did not grow well, thin and thin as if terminally ill. "These are the trees Zhu Chuchu said, just planted on the sidewalk, I feel like I can't stop anyone, I can see it when I come and go."

Li Nan nodded: "Yes." We had no way of taking a polygraph on her, so we had to find a way to cross-corroborate her with facts or other testimony. ”

"Is she a bad person?"

"She's an ordinary person."

The two had planned to go to the library to check the local newspaper, but Li Nan's phone rang, and it was her husband who called and asked where she was.

"I'm out there with a friend, investigating the details of a commission."

"It's a weekend, and you're usually too busy to be at home, so why are you even busier after you get married?" Wei Zhiyu said, "Our mother is here, come back quickly." ”

"Well, I'll be right over."

Sitting in the car, Li Nan leaned against the window, she and Wei Zhiyu met at a three-month dinner, when Wei Zhiyu came to a friend who entrusted the case, and it was a case of investigating corruption within the company.

According to his own words, he fell in love with Li Nan at first sight.

After eating that night, it became a movie session for the two of them, and then they caught up with Li Nan.

Wei Zhiyu's family was not good when he was a child, but in recent years, he has risen to the top and has become a veritable rich second generation, and occasionally has the temper of a young master.

When he was about to enter the house, Li Nan took out a pair of high heels from his bag and changed them in, and when he entered the house, the lights were bright, and it was time for dinner.

The meal was very dull as the mother-in-law was chatting around a central idea, which was to ask when they were going to have a baby.

The question derived from this question is when Li Nan will resign.

"Your job is so busy and consumes too much energy, and our family doesn't need you to work hard...... Oh, I'm telling you, oh, it's not that I'm going to urge you just got married, young man, you're in good health, and you're recovering quickly. ”

Li Nan didn't refute either, and concentrated on eating a braised rib on the table.

"We'll think about it." Wei Zhiyu said.

This house is their new home, which has been renovated and ventilated half a year ago, and they didn't even know each other at that time. Li Nan knew it on the first day he moved in, Wei Zhiyu was probably pushed to the extreme by his family, no matter who he was this year, he would find someone to be the hostess here.

It's a big place, usually the two of them live, Wei Zhiyu doesn't like the feeling of outsiders at home, so the housekeeping comes to clean during the day when they go to work.

"If you talk about our mother, don't take it to heart, she has always been worried about it." Wei Zhiyu hugged her from behind, "You like your work, just do it first." ”

Li Nan nodded meekly and lowered his eyes.

"I love you."

The next time I saw Zhu Chuchu, it was not at her house, but in the garden of the family area of the seafood factory, Zhu Chuchu was wearing an old black coat, and he was arguing with people with his left arm on his red face. Her voice was not loud, quite sharp: "Your dog is not optimistic, running out everywhere to bite people, dogs raise dogs, you are!" ”

The owner of the dog is a couple, and one of them is a young man, who is also very angry: "Why did Mobao bite you!" It's been very well-behaved since it was a child, what are you doing biting you old weird woman, you're spewing blood here and trying to slander me! ”

In the middle of the two, lies a dead puppy, a brown curly-haired teacup teddy, and a cute hooded Superman suit. The dog's eyes were closed, and there was a large pool of blood underneath him.

Mo Kexin squatted down and touched the puppy, which had no heartbeat or temperature at all.

The crowd around the side commented, some people said that the dog did not have a leash, and the young man held the leash indignantly, "Why not, I was just going to let it play in this flower bed before it was untied!" ”

Zhu Chuchu retorted: "It's on the side of the road, just rush over and bite me, fortunately I didn't bite it because I was thickly dressed, I just took this stone and wanted to drive it away, I just threw you and pushed me to the ground, causing my arm to hurt!" ”

The incident happened suddenly, and it was a remote corner, no one noticed the conflict between this person and a dog, and this place was a blind spot for monitoring.

The young husband said that it was Zhu Chuchu who took the initiative to beat the dog, and he did not push the person, but she fell down by herself and asked her to compensate, while Zhu Chuchu said that the dog wanted to bite herself, was pushed to the ground, and also needed medical expenses. I don't know who in the crowd commented: "I see that this puppy is very clever and cute, how can he just bite you?" ”

"That's right, and how can such a big puppy take the initiative to bite someone."

Zhu Chuchu in the crowd stared at him and trembled with anger. Li Nan knew that they had called the police, but in this case, they also insisted on their own words and mediated with each other.

After a while, the police arrived, but they were also helpless about this situation, and onlookers criticized Zhu Chuchu for "being disrespectful to the elderly".

"In these years, the old man himself fell and framed others, I don't know how many people ......"

"How to say it on the Internet, it's not that good people have become bad, but that bad people have become old."

Zhu Chuchu was surrounded in the middle of the crowd, like a weak female beast, she was too old, too undignified, the little couple opposite called a bunch of people, and she was carrying a few plastic bags for grocery shopping, and her eyes were red and standing.

"As long as you lose money, you can't pay any amount for our emotional damage, but our Mobao cost more ......than 7,000 when we bought it," said the wife.

The police dispersed the crowd of onlookers and decided to bring the three back to the bureau for mediation. Li Nan glanced at his police number, stepped forward and handed out a business card of his own: "Hello, I am a polygraph detector who cooperates with Weihu Police...... If you have a need, you can entrust it to us. ”

After accepting the business card, the little policeman said to the crowd around him: "Go, go, the idlers and others have all stepped aside and dispersed." ”

The crowd was scattered.

Li Nan was thinking about the next step to go to the creditor to ask about the situation, turned his head and saw that Wei Kexin had taken off his coat and carefully wrapped the puppy on the ground.

"It's dead, it can't be saved." Li Nan said.

"I know," Mo Kexin carried it to the side of the flower bed, and snorted and opened a small mound with his hand, "but what does the human quarrel have to do with it, this little puppy that has been bred and bred is originally deformed...... Even if nothing happens, it won't live long. ”

"There is also a difference between life and life." Li Nan stood and watched her busy.

Mo Kexin was stunned for a moment, and retorted rarely: "It's nothing different." ”

"Childish."

Li Nan is too lazy to compete with her, just like seeing my ideals written in my primary school essay and people who grew up in reality, they eventually need to realize the huge difference between the two by themselves.

"Nothing different." Mo Kexin repeated it again.

originally thought that today's visit plan was in vain, but half an hour later, Li Nan received a call from the police station.

The parties unanimously requested a polygraph test.

Li Nan agreed undeniably.

Contrary to popular belief, polygraph is not a metaphysics, but essentially a psychological experiment. The polygraph tester needs to use logic as a network to construct a set of test questions, using objective human reactions as a benchmark to find the "psychological traces" of the person being tested.

In this dispute, Li Nan listed the key points one by one:

First, did the dog bite the victim first, or did the victim hit the dog first to vent?

Second, was the victim's arm injury caused by his own fall, or was it caused by being pushed?

Wei Kexin had never been exposed to polygraphs before, and when he saw those professional instruments, he exclaimed again and again, and he was afraid that he would break them, and after a while, he looked at Li Nan with little stars in his eyes: "Do you have mind reading skills?!" ”

"Nope."

"I think you have! You can't just measure ...... with instruments Is this really a lie? ”

"Of course not, those feelings, thoughts in the heart, and actions that do not appear objectively are not within the scope of the test."

"That's ......"

Mo Kexin looked for a book in the laboratory and read it.

"Don't you have anything else to do?" Li Nan couldn't help but ask.

"Apparently not."

“……”

After preparing the necessary matters before the polygraph, Li Nan made an appointment with Zhu Chuchu and the husband of the couple to take the polygraph test, and the wife was unable to participate due to something.

The time was arranged for two mornings, and Li Nan went through the cause of the incident again with great interest.

When she closed her eyes, she could still hear a myriad of voices: pleading, pleading, confident, weak, angry, swearing......
