Xu Yao listened carefully to Liu Xiaobo's report. During the investigation, he learned that the security guard had a good relationship with Liu Lidan, so the security guard had not changed jobs since he was hired and had worked diligently for six years.

The security guard should have nothing to do with this case. If he is responsible, he can only be blamed for being absent from duty, but this is not a matter for the law.

After Liu Xiaobo left, Xu Yao kept thinking about the question from last night: Why did someone take the telescope away from the scene?

What role did the telescope play in the case?

Xu Yao once again took out the items used to threaten Liu Lidan, and pulled out a letter with the words written on it from a newspaper:

"I love you so much, but you are willing to hurt me.

Why is it you? I can't face this reality."

Xu Yao looked at the information revealed in the letter, puzzled.

Could it be that this threat is a secret admirer of Liu Lidan?

The person who said this must not be Huang Yousheng's wife Liu Yuemei.

From the current clues, no one can answer this question, and Xu Yao himself can't.

He felt more and more powerless. Since he became a policeman for more than ten years, he has encountered many difficult cases.

But there are rarely such complicated cases one after another. Is it a coincidence or intentional?

Longhai City sent a message that Liu Yuemei has been arrested and is now being escorted to Jiangsha City.

Xu Yao is 99% sure that Liu Yuemei must have participated in this case.

Lao Li also received news that Liu Lidan's rumored boyfriend, who was filming in the desert, has contacted him.

But the result was not satisfactory. He also had an alibi. He already had a new girlfriend. On the night of Liu Lidan's accident, he happened to be at home with his new girlfriend.

Now he is getting more and more confused. Xu Yao can't guess who wants to stab Liu Lidan.

If you just stole money, he can just take the valuables and leave. There is no need to do this.

Xu Yao guessed that during the time when Liu Lidan died, there should be more than three people who entered her room. One was Huang Yousheng, one was Liu Yuemei, one was a burglar, and the other was a mysterious person.

The only thing he could do now was to get information from Liu Yuemei.

Liu Yuemei's escort process was very smooth. She arrived in Kangsar City at 10 am the next day and was detained in the detention room of the city criminal police team.

At 2 pm the next day, Xu Yao brought Mo Xiaoqing into the interrogation room.

Their arrival made Liu Yuemei's face full of shock.

Mo Xiaoqing spoke first, "Hello, Madam Liu, we meet again, but this time your identity has changed.

Now you are no longer the suspect's wife, but the suspect herself."

Liu Yuemei sat on the chair with her huge body, swaying. Mo Xiaoqing was afraid that the chair would collapse under her sitting.

"Yes, we meet again, two police comrades. I don't quite understand what you said just now. What do you mean by I have become a murder suspect?"

Xu Yao did not intend to waste words with her, "Mrs. Liu, you are a smart person. There is no need for you to perform such poor acting in front of us.

You were brought all the way from Longhai City to Kangsar City. It is definitely not to invite you to have tea with our criminal police team.

You are now suspected of a murder case, and from the evidence we have obtained, you are the mastermind!

Now please confess the murder process in detail."

Xu Yao's voice had a very stern and intimidating feeling. When he looked at her with an aggressive look, Liu Yuemei's body trembled slightly, and her voice began to hesitate:

"You...what do you mean? You actually suspect that I am the one who killed Liu Lidan, it's ridiculous!

A few days ago you still suspected that it was my husband who did it, but now you turn the blame on me. Are you police officers so casual in handling cases?"

Xu Yao was very calm, and asked again: "Do you mean that Liu Lidan was killed by your husband?"

"It's obvious, police comrade. Although I hate Liu Lidan, I really don't have the courage to kill her. If I wanted to kill him, I should have done it a few years ago. Why wait until now?"

When Liu Yuemei said this, she rubbed her hands tightly together, and it was obvious that she was very nervous.

"Mrs. Liu, at this point, there is no need for you to keep lying. We have seen through your tactics of blaming others for your own crimes, so you'd better tell the truth!" Mo Xiaoqing interrupted.

"I... I have nothing to say, I didn't do anything."

Xu Yao's face turned gloomy, and he said, "Oh? Well, since you don't want to say it, let me say it for you."

He spread out the documents on the desk, "This is a forensic report. They detected a very special nail polish from the dirt on Liu Lidan's nails.

You should still remember that when I went to your villa with my assistant, my assistant once smelled the unique scent of your nail polish.

And you also told her that this nail polish is unique in the world and was specially prepared for you by your nail artist.

It is your character of pursuing unique temperament that exposed you. After testing, the proportion of the nail polish in Liu Lidan's nails is exactly the same as that in the house." Liu

Yanmei began to argue, "My nail polish is indeed specially prepared by the manicurist, but what can it prove! I always give some to friends from time to time.

So just commenting on a nail polish report, I want to prove that the nail polish left in Liu Lidan's nails belongs to me, isn't it too hasty!"

Xu Yao guessed that Liu Yuemei might use this trick, and said calmly:

"You mean you didn't kill Liu Lidan, right! Answer me loudly!"

Xu Yao's voice was almost a roar.

Liu Yuemei's huge body trembled slightly, her eyes did not dare to look at Xu Yao, and she glanced around,

"I don't know what you are talking about, but I didn't kill her anyway. Although Liu Li deserves to die, she destroyed other people's families. Even if she goes to Yanluo Palace, she will be thrown into the eighteenth level of hell."

Liu Yuemei yelled in a sharp voice, staring straight ahead, and her right hand unconsciously stroking her left fingernails.

Mo Xiaoqing couldn't believe that Liu Yuemei would be so shameless. Now that the evidence is confirmed, she still wants to deny it.

She couldn't think of a way, so she had to cast a trusting look at Xu Yao.

Mo Xiaoqing turned her eyes and saw Xu Yao was unusually calm, with his hands crossed in front of his chest, observing Liu Yuemei like a bystander.

He slowly began to speak: "A recent study by psychologists at the University of California, USA, found that even the most frequent liars will have subconscious signals that can be caught when their brains switch to pretend mode. Ordinary people can catch liars' lies just like a polygraph.

When lying, the eyes will look to the upper right. Liars never look into your eyes. And when you say something that is inconsistent with the facts, you always dare not look into the eyes of our two police officers.

Sudden changes in volume and tone. Liars' voices will unconsciously rise. The rise in tone when lying is often because the liar To cover up their weak hearts.

Liars always like to touch themselves, just like chimpanzees will dress up more when they are depressed.

Liu Yuemei, you became extremely sharp when you said that, and you always grind your left fingernails unconsciously.

You are lying!

If you think that these are not enough to make you speak, there will be a way.

Now a kind of lie tester is usually used in domestic interrogations. This thing is not a big deal, but I heard that sometimes there will be some small accidents, such as leakage of electricity. "
