October 2, 2018, the third day of the National Day holiday. But this holiday never belonged to us. Early in the morning I got out of bed again as usual, and I looked out the window. There are obviously not as many cars on the streets as there are weekdays, and the leisurely nature of the long holiday slows down the clock in the city. And we are the most important part of this clock, and maintaining long-term peace and stability will make this clock go at the speed that people imagine.

The car on the long holiday is also very difficult to drive, and most of the private cars on the street are traveling collectively with a few families, and the busyness of the working day is swept away. I could only walk 3 km from my house to take the bus. The last time I took the bus was when I was in college, and the speed of the bus obviously didn't meet my requirements because of my work. After waiting for a while, the bus came, and I got on the bus and chose a window seat, which was also a very lucky thing to be able to sit on the bus. Because there are not many people, I arrived at the unit quickly.

The first thing I did when I entered the office was that the captain asked me to summon, Ye Li, Bai Hao and Na Yongbo. I told them to come to the police station at 10 a.m., as he had instructed. I wondered if the three of them shouldn't be the same person, as the captain reasoned yesterday afternoon.

Just when I kept thinking about this problem, I received calls from Ye Li and Bai Hao one after another, the former saying that he was still out of town and needed to come back at noon, and the other said that he needed to follow a performance in the morning and could not arrive until the afternoon. I told my captain about it.

"Well, they've fallen into our trap."

"I seem to understand why they staggered, do you want to judge by fingerprints?"

"No, no, no, if my reasoning is correct then he will be transfigured, and this one will easily change the fingerprints, you just wait for my good show."

Just before they arrived, our captain asked me to put a glass of water at the prisoner's table in the interrogation room. I don't know why he did it. Soon the entrepreneur Na Yongbo came, and the captain and I were in charge of his interrogation. The captain who sat next to me kept talking to him about homely things, both about entrepreneurship and about his future family. It's just how to ask if it has nothing to do with this case. Suddenly, the captain shouted loudly in the peaceful conversation between the two of them!

"Are you a murderer?"

When I was asked so suddenly, I saw that Yongbo's face instantly darkened, and he didn't seem to know how to answer, but he swallowed his saliva and picked up the glass of water we had prepared in advance next to him and drank it in a big gulp. He said slowly.

"How could it be me, don't make this joke."

The captain also laughed when he heard this, and ended the interrogation. I saw that after the interrogation, the captain whispered a few words to his colleagues in the forensic team, saying that I had no way of knowing. Soon at noon, Ye Li also came, and we also prepared a glass of water in advance. There was no surprise attack this time, the captain just kept talking to him about literature and history.

"What do you think of the historical status of Murder on the Orient Express, I think it's a little worse than Sherlock Holmes."

This sentence opened Ye Li's chatterbox, and he spoke for twenty minutes. As soon as this topic ended, the captain hurriedly followed up with a question.

"Is there ever an Atlantis in history? What kind of place is he? ”

This ignorant sentence provoked Ye Li's words again, and he kept talking about his theory. It seems that I have forgotten that this is an interrogation scene. Soon Ye Li was already a little tired, and I saw him lowering his voice while swallowing his saliva. Finally, he couldn't help but drink the water that was placed next to him. After drinking, the captain asked some innocuous questions about the case, and the trial ended.

Immediately after this time, I took another glass of water and put it on the table, but I was stopped by the captain, who asked me to make a cup of fine green tea and put it on the table to wait for Bai Hao's arrival. It sounded a little vague to me, but I had to do it.

Soon Bai Hao came, and this time the interrogation task was handed over to Liu Xiaoyu, I don't understand if Liu Xiaoyu can ask as clearly as the captain, but I don't dare to say because this decision was proposed by the captain. Obviously, my doubts are unfounded. Bai Hao, who had just sat down, took a sip of green tea. The interrogation was almost over, and as soon as Bai Hao left, I asked the captain why he did this.

"Quite simply, a person's fingerprint may be changed, but his DNA can't, and if he can't be forced to take a blood test, it's better to find another way."

"Could it be saliva?"

"That's right, it's saliva, Nayongbo is a cautious person, and if I suddenly ask him, he will be so nervous that he will drink water, and his saliva will be left on the quilt. The second Ye Li personality is a professor who is very rigorous in academics, if I ask a mentally retarded question, he will definitely explain patiently, and in the process of explaining this, he will be thirsty and drink water, and the third one is simpler and the easiest, that is, Bai Hao personality as a makeup artist must care about his Lian very much, if I have a cup of green tea there, he will definitely drink it without any worries, because green tea is the best for the skin among all drinks. That's it, and if you study carefully, you'll know these interesting two ways to do it. ”

I was shocked, on this day we all cooperated with our captain to perform a play, a good show that can occasionally see the clouds.

Soon we received a notification from the forensic team, and everyone must know the outcome. The DNA of these three people is exactly the same, and they belong to the same person!

All the evidence was conclusive, and all that remained was the mysterious fresco of his house, and the captain and I had decided that we were going to visit at seven o'clock tonight, and this time it was not an infiltration, nor an arrest, but a normal visitor.

We informed Na Yongbo, and as an entrepreneur, he did not refuse but expressed his welcome. We were also dressed up very formally, and told him on the phone that the reason we were going this time was simply to visit friends.

The captain and I came to Nayongbo's villa in the center of the city on time at seven o'clock, don't look at the fact that although it is the city center, his house does not have too much hustle and bustle, because it is a rich area, so the people of Xia Riba rarely appear here. I lamented that I had found a paradise in this prosperous city of Sangju, with rockeries and ponds. I didn't have time to appreciate the scene in front of me, which I had never seen before, but I was interrupted by Na Yongbo, who was enthusiastically going out to meet the new year. We also greeted politely and said that we had come here to thank him for his sponsorship and to apologize for disturbing him so often lately, and we exchanged a few more pleasantries and went inside.

After entering the house, I was shocked by the scene in front of me, with world-famous paintings hanging on the walls, precious furniture on the floor, and ancient artworks on the walls. But no matter how I looked, I couldn't see the portraits of historical figures and the symbol of the black spider that Cao Yang said. I looked at the captain in confusion, but the captain didn't pay any attention to me, he just walked around the room while enjoying the artwork. After walking for a while, he said, "Let's go to the courtyard and talk, it's a little hot in the house." ”

After that, the three of us went out together, and after we got out, the captain also paced around the courtyard while talking. I don't know what he's doing, but I can't help it.

"May I ask Mr. Nayongbo, do you have any other portraits in your family?"

"No, that's all! Why, you ask? ”

I was about to talk about the portrait of the historical figure when I was interrupted by the captain, who put his arm around me and said.

"You can't afford these paintings, you think you're going to a flea market to buy them."

The three of us laughed, and after a long talk we came and left. Afterwards, I learned that the captain was pacing around to measure the length and width of the house, and he found that the length of the house needed to walk thirty steps, and the outside of the house needed to walk thirty-five steps, so the extra five steps were the places where he hid the secret scroll, and he found that there was the color of paint behind the scroll hanging in the innermost part of the scroll, so it was enough to show that these paintings were hung up after painting the wall, and when was this innermost wall built, through the captain's reasoning, it should have been built overnight after Cao Yang sneaked in. I accompanied our captain for a whole day on this day, and I think his acting skills can be convincing to win the Oscar.

When I came home in the evening, I kept lamenting what happened today, what a show!
