In the ward, I saw Xu Tianwu lying on the hospital bed looking at the ceiling, and his wife was no longer around.

Lao Lu walked to Xu Tianwu's side and said coldly: "Xu Tianwu, I suspect that you murdered Wu Qiguo, please come with us." ”

While Lao Lu was talking, I walked to the nursing chair and opened Xu Tianwu's toolkit. He took out a pair of cotton and linen gloves from inside, looked at them carefully, and then quietly put them in his coat pocket. However, I didn't find what I was really looking for, and I couldn't immediately prove that Xu Tianwu was the murderer, which surprised me.

I stood up and looked at Xu Tianwu on the hospital bed, he didn't say a word, he still had an unpredictable calmness, and followed Lao Lu very cooperatively.

In the interrogation room of the criminal investigation team, Lao Lu personally interrogated Xu Tianwu, I watched Xu Tianwu's every move in the monitoring room, he was still calm, and the answers to various questions seemed to be so innocent. It's just that when Lao Lu mentioned that his motive for committing the crime was to take revenge on Wu Qiguo and his wife, Xu Tianwu's composure suddenly disappeared. His whole body was trembling, his eyes blinking, his powerful fists clenched tightly, and he refused to answer any more questions. No matter how Lao Lu roared, he was still like a stubborn stone, becoming silent, but it could be seen that there was churning lava inside the stubborn stone.

Lao Lu had no choice, so he opened the iron door of the interrogation room and threw the door out.

I walked up to the angry Lao Lu and said, "Lao Lu, it seems that I made a mistake in my judgment, and my mistake is not that I can't be sure that the person was killed by Xu Tianwu, but that Xu Tianwu's motive for killing was not his wife's cheating." Judging from his performance just now, he only knew that his wife was cheating. ”

"Ouyang, you kid aren't kidding me!" Lao Lu said impatiently.

"Xu Tianwu's wife, did you send someone to keep an eye on it?" I asked.

"Xiao Liu is staring." Lao Lu lit a cigarette and said.

I said softly: "Let Xu Tianwu go, and send a few more people to follow his wife, Xu Tianwu is stared at by me and Zhenguo." ”

Lao Lu glared at me and said, "Aren't you fooling around, don't I know what you mean?" Do you want to let Xu Tianwu, a suspect, out and kill his wife again? I can't do such a thing without regard for the safety of the people. ”

I didn't say anything, and I knew that this was not the proper way for the police to handle the case. It's just that I know that in this case, after 24 hours, Xu Tianwu will still walk out of the police station.

I sighed and said to Lao Lu, "I'll go back to the scene of the crime and take a look." ”

Lao Lu was upset, smoked and ignored me, so Tang Zhenguo and I walked out of the criminal investigation team. Walking to the gate, I took out my mobile phone and sent a WeChat message to Lao Lu: Notify me when Xu Tianwu is released.

At this time, it was getting late, and Tang Zhenguo and I randomly found a restaurant and ordered a few stir-fried dishes. During the meal, Tang Zhenguo asked me curiously: "Why are you so sure that Xu Tianwu killed Wu Qiguo?" ”

"Because from the point of view of the modus operandi, only Xu Tianwu has this possibility." I said as I ate.

"What's the method?" Tang Zhenguo asked with interest.

"Eat, eat, I'll tell you when I figure everything out." I continued to grill the rice.

Tang Zhenguo nodded and ate as well.

In fact, I also have a fog in my heart, and I can't explain it to Tang Zhenguo now. The motive for the murder was denied, and the tools of the crime were not found. I looked through Xu Tianwu's kit before, and I suspected that the crime tool was in his bag, but I couldn't find it, and what I was looking for was a gas hose larger than three meters long.

After eating, Zhenguo and I hired a taxi and went straight to the scene of the crime, because I knew that since the tools of the crime were not taken away, it was very likely that they would stay at the scene of the crime.

Come to 1709A, Room 302, North Hill Road. At this point, the door was locked, but unlocking it was a trivial matter for a consulting detective.

Effortlessly, the door opened, and we were at the scene of death again. I said to Tang Zhenguo: "The scene of the crime has been investigated, so we don't have to worry about destroying the scene, let go of our hands and find a gas hose." ”

After speaking, I turned on the mobile phone light, but at this time, my eyes lit up, and the whole living room was bright and transparent, because Tang Zhenguo had already turned on the light in the living room. I looked at Tang Zhenguo in a daze, the mobile phone light in my hand was still on, but Tang Zhenguo said in a serious way: "I'll go to the master bedroom, you look outside." With that, he rushed into the master bedroom and fumbled for a while to turn on the light in the master bedroom.

Interesting! I simply turned off the light on my phone and searched in the living room with great fanfare.

It's just that the area of this house is not large, and it is not difficult to find a three-meter-long gas hose, but we have searched all the places we can find, but we still can't find it.

"Ouyang, there's no gas hose you said, but there is a roll of water pipe hanging behind the bathroom door." Tang Zhenguo said to me.

"Water pipes?" As soon as this term appeared in my mind, I suddenly snorted, and then said with a smile: "Zhenguo, there is you." ”

I strode to the bathroom and easily found the old tan water pipe, about four meters long. Judging from the traces of the water pipe's display, this pipe should have been placed here for a long time and used occasionally.

I inspected one end of the hose and found that the pipe, about two centimeters from the nozzle, was very sticky, and there were some white fibers stuck to the sticky parts. When I saw this, it dawned on me.

I said excitedly to Tang Zhenguo: "Zhenguo, go find a plastic bag, I want to take this water pipe to Lao Lu." ”

Tang Zhenguo snorted, rummaged around the kitchen for a while, and found a plastic bag. We put the hose in a plastic bag and turned off the lights to go home.

In the afternoon of the next day, Lao Lu called and said that Xu Tianwu had been released, but two colleagues had been sent to keep an eye on him. I asked Lao Lu for the phone number of the stalking police, and together with Tang Zhenguo, I also joined the stalking team.

In the next two days, Xu Tianwu did not have anything unusual, but learned from Lao Lu that they had protected Xu Tianwu's wife, and his wife was now in a hotel in the city. His wife was very scared when she learned that Xu Tianwu already knew about her cheating, and she was very cooperative with the police.

However, Xu Tianwu was not abnormal in the past two days, and at noon on the third day of monitoring him, he returned to Qinglongyan to continue to beat stones. However, there was an accident on the way, and the scaffolding built by Qinglongyan suddenly collapsed, and Xu Tianwu fell from the scaffolding, but fortunately, Xu Tianwu was not seriously injured, and he stood up after falling.

After he fell, the surrounding people were still very enthusiastic and took him to the nearby Pinghu Hospital to treat his wounds. The four of us who monitored did not show up in order not to startle the snake. After confirming that Xu Tianwu was fine, he continued to monitor.

It's just that since then, the residents around Qinglongyan have exploded, saying that the dragon has appeared again, first taking the life of a stonemason, and now coming to take the life of a second stonemason. The rumors spread like gods, and there were many things. And the incense of Qinglongyan is also more vigorous during this time. Of course, after these two incidents, the matter of beating Qinglongyan was stranded again.

Lao Lu rushed over to consult with his two subordinates about the situation, and felt very puzzled, and I could see from his expression that he was a little overwhelmed.

One of the policemen in charge of monitoring said: "Didn't there also happen a mysterious death of a stonemason who hit Qinglongyan a few years ago? Could it be that these cases are really dragon apparitions? ”

If it was before, Lao Lu would definitely scold this policeman, but at this time, Lao Lu was silent.

I pulled Lao Lu aside and said to him solemnly: "Do you believe me, an old classmate, or do you believe the rumors outside?" ”

Lao Lu frowned and looked at me, didn't answer directly, walked up to the two policemen and said, "You go back to the team, Xu Tianwu and I will look at it." ”

The two policemen glanced at each other and took a taxi away.

In the next few days, Lao Lu and Tang Zhenguo and I continued to monitor Xu Tianwu, but this Xu Tianwu stayed at home after he was injured, except for taking out a takeout for dinner, there was no abnormal behavior, and he didn't even go out to find his daughter-in-law. This kind of non-abnormal behavior makes me feel that he is even more extraordinary.

There is another thing that I find very interesting, and that is Tang Zhenguo. He took a great interest in what I was doing, and he forgot to eat and sleep with us, and even forgot that he had to look for a job.

Another morning, it was raining moderately and it was dark. I thought that in this kind of weather, the three of us would probably spend another day in the car. Unexpectedly, Xu Tianwu actually carried a sports bag and went out with an umbrella.

After he went out, he waited on the side of the road and got into a red Chang'an Yuexiang, which seemed to be a Didi taxi called in advance.

We drove after him, he got off the car in Gaosuntang, and Lao Lu also parked the car on the side of the road, regardless of whether it violated the rules or not.

The three of us followed Xu Tianwu in the rain, all the way through the high bamboo pond to Pigeon Ditch.

I saw Xu Tianwu carrying his sports bag into an antique shop. The three of us stood far outside the antique shop, and continued to wait.

After about twenty minutes, Xu Tianwu walked out of the antique shop with a radiant expression on his face.

I hurriedly said to Tang Zhenguo: "Zhenguo, you continue to follow Xu Tianwu, do you have any situation to contact by phone." ”

Tang Zhenguo snorted, stood up with his collar, and rushed into the rain.

I said to Lao Lu, "Let's go to the antique shop." ”

When you enter the antique shop, you know that it is really quaint and magnificent, but it is more quiet and elegant.

Except for a security guard by the door, there was only one bald fat man in the store. The fat man sat at an intricately carved brown wood tea table, flipping over and over at a piece of jade in his hand. His dress was very heroic, and the gold chain with the thickness of a little thumb exposed around his neck showed that he was obviously not as simple as a clerk.
