"Wang Xiaoming's death was between 9 o'clock last night and 0:00 this morning, and the fire in his house was close to midnight. If Wang Xiaoming died by homicide, then there is undoubtedly some inevitable connection between these two events, both in terms of cause and effect and chronological order. Meng Xingchen said as he walked.

"The easiest scenario, then, is that the killer first killed Wang Xiaoming by the lake, then rushed to the village and set fire to the house where he lived, and the motive for the latter move was apparently to destroy something related to the case. Shui Bingyu continued.

After the two made this inference, they immediately went straight to Wang Xiaoming's house without stopping, secretly praying in their hearts that after being swept by the fire, there would still be some valuable clues left there.

Most of the villagers went to the "Ghost Lake" to watch the excitement, and the scene of the fire that was buzzing last night is now deserted. The scene here is disappointing: the damage to the house is very complete. The roof had collapsed, leaving the walls with only black ruins, and the furniture in the house had been reduced to ashes, except for a few broken clay pots and clay bowls that still had some of their old appearance.

But Shui Bingyu and Meng Xingchen did not give up: being able to find valuable clues where others did not have hope was originally the quality that a good detective should have.

They searched through the scorched earth and rubble, sparing no corner.

Their strange behavior attracted several villagers who lived nearby, who curiously stepped forward to watch, occasionally whispering to each other.

Finally, a woman in her forties couldn't help but say to Shui Bingyu: "Girl, you are a foreigner, right? Don't rummage, it's impossible to find something valuable!"

At this time, I heard an old man sigh and say: "Hey! This bastard boy has never left his wine bottle all day long, and he has never been sober! I have said a long time ago that he will drink to death one day! Alas, it is really not what I expected! This is really God wants to cut off the old Hao family!"

"Old Hao's family, isn't his name Wang Xiaoming, and what does it have to do with the old Hao family?" When Shui Bingyu heard about the old Hao family, she couldn't help but be shocked, and hurriedly asked.

"This Wang Xiaoming! was originally a child from Haojia Village. Back then, his parents passed away one after another, and there were no relatives willing to raise him, so he was adopted by the kind-hearted Dr. Wang's family, and his name was changed to Wang Xiaoming. Dr. and Mrs. Wang have never had a child of their own in their lives, and they regard Wang Xiaoming as their own pet! But they didn't expect that this child would grow up like this! As soon as the couple died, it didn't take long for him to lose all his family! In the end, even his life was gone!" The old man sighed.

"Old man, do you know Hao Ming from Haojia Village?" Meng Xingchen continued to ask.

The old man was stunned for a moment, did not answer, raised his head and stared at Meng Xingchen up and down suspiciously.

Meng Xingchen understood what he meant, hurriedly took out his work card from the pocket of his clothes, and explained with a smile: "Old man, I am a police officer in Kyoto City, and I have to know about some of Wang Xiaoming's related information." ”

"Hao Ming?" the old man pondered for a moment and said, "Is it the one who is a little mentally abnormal?"

"Yes, it's him!Do you know about him?" Shui Bingyu asked excitedly when she heard this.

"Hey, I know this crazy boy, I'm lucky enough to have three lives. The old man said slowly.

Shui Bingyu smiled and said, "The last time you saw him, he wasn't very old, right? He's almost sixty now." ”

The old man was obviously a little surprised: "Don't say it, it's true, it's really been so many years." ”

Shui Bingyu knew that Hao Ming, a mentally ill person, would not have the police to go door-to-door to do such an in-depth investigation. If Hao Ming hadn't taken the initiative to find himself and take the initiative to be associated with the blood book case, his previous weird behavior would not have been exposed.

Meng Xingchen asked, "When did Hao Ming go insane, and what caused it? Can you tell us?"

"Hey! Hao Ming, this kid is also a hard-working child! Originally, he was smart and studious, and he was the only child in Haojia Village who was admitted to university! Moreover, after graduating from college, he returned here to become a teacher in order for the children in the village to go to school and study. Later, she married a beautiful daughter-in-law, named Ma Xiaohui, who looks like a water spirit, and is also a teacher in school, who loves to sing and dance. In the second year after marriage, the two had a daughter, which was originally a small family that everyone envied. But after all, there are still some problems in their family, Hao Ming is too obsessed with his chemical research experiments! Sometimes he conducts research at school all night long! Ma Xiaohui takes her children by herself, and sometimes she also goes to rehearse a show and perform, so it is inevitable that there will be inconsistencies between the husband and wife in terms of arrangement. ”

Could it be that Hao Ming's mental problems were all caused by discordant family conflicts? Shui Bingyu couldn't help but think to herself.

The couple has always been so awkward, and the contradiction became more and more obvious, until one day, Ma Xiaohui took her 5-month-old child and left. ”

"Gone?" Shui Bingyu asked, "Did you leave on your own initiative?"

The old man said: "Ma Xiaohui is so beautiful, even if she has given birth to a child, at first glance she is no different from a girl or a girl, and she is absolutely indispensable to covet her, and she is in the literary circle all day long, and some things between men and women are not clear." Tell me, would it be strange for her to leave a dirt village in such a situation? So, of course, she left on her own initiative. ”

"Where did she go?" asked Shui Bingyu.

A loveless home, discord between husband and wife, escape at night, deep pits, mutilation of small animals, venting of dissatisfaction.

"I don't know, no one knows. People in our village guessed that they must have run away with some rich man in the city. Hao Ming frantically searched for a while, and the people in the village also helped to inquire around for a while, but there was no news. It didn't take long for Hao Ming to become insane, running around, and finally disappearing. Hey, a good child, a good home, all ruined!"

Shui Bingyu asked, "Then what is the relationship between Wang Xiaoming and Hao Ming?"

"According to blood relations, Wang Xiaoming should be Hao Ming's nephew, and he is the child of Hao Ming's elder brother. ”

Shui Bingyu said to herself: "Hao Ming's nephew, could it be that what he wants to tell me has something to do with Hao Ming? Could it be that his death has something to do with Hao Ming?"

At this time, a man patted his head again and again, looking remorseful: "Why didn't I think something would happen to him? If I had known this, I should have gone to his house yesterday to ask for an account, which is much more useful than keeping that broken IOU now!"

The old man gave him a blank look: "How much does he owe you?" It is really strange that he actually made an IOU, I see that he has never planned to repay the money he borrowed. ”

"It's not too much, a hundred. The man stretched out his hand and scratched his head, "Who knows what happened yesterday, he offered to write an IOU first, and what else to say, or in two days, he will be able to pay back all the money owed to the people in the village......"

"How much does Wang Xiaoming owe the villagers?" Meng Xingchen asked the man.

"That's a lot, you fifty, he is a hundred, I think it must add up to three or four thousand. ”

"Hmm. Meng Xingchen lowered his head and muttered for a moment, "What about your IOU, can you show me?"

The man suddenly realized, and hurriedly took out a piece of paper from his pocket, handed it to Meng Xingchen, and at the same time patted his chest and swore and said: "The date and signature on this are all true, it is absolutely true, and the government has to make the decision for me." ”

The old man sneered: "You have it, people are here to investigate Wang Xiaoming's death and yesterday's fire, who cares about your broken account." Everyone around laughed, and the man touched his nose, looking very embarrassed.

Meng Xingchen and Shui Bingyu looked at the IOU together, only to see that it read:

"IOU

I owe Chen Ergou 100 yuan, and I will return it ten days later.

Wang Xiaoming, March 1, 2016"

A few lines of words are written crookedly, and it is indeed like the person.

Through the morning light, Shui Bingyu found that there were still some faint traces of the note, he turned the note over, and sure enough, there was also a line of words written on the back, and the content of this line of words made her can't help but be excited:

"Someone came looking for the missing girl, and he promised to give me 2,000 yuan and let me tell ......"

There is another word after the "sue" of "tell", which has just been written halfway, and judging from the strokes, it should be the word "he".

"When did Wang Xiaoming give you the IOU yesterday?What was he doing when you went?Is there anyone else in the house?" Shui Bingyu threw out several questions in a row.

"It's probably about seven o'clock in the evening. Seeing that the police attached great importance to the clues he provided, the man couldn't help but feel that he had regained some face, and raised his voice and replied, "He was alone in the room." He was about to go out, and after we had a conversation, he took a piece of paper from the table and wrote this IOU to me. By the way, he seems to have just finished writing something, and the pen and paper have not been put away yet. ”

Looking at the piece of paper, Shui Bingyu's brain spun rapidly. Obviously, this is a note that was invalidated after being written halfway, and the reason why it was not finished was probably because there was a change in the content, which made Wang Xiaoming rewrite it on another piece of paper. Later, Chen Ergou came to ask for the account, and he picked up the waste paper and wrote the IOU on the back.

What does the incomplete content of the note represent?

The missing girl is Liu Lu!

Wang Xiaoming's second uncle is Hao Ming!

Could it be that Wang Xiaoming discovered Hao Ming's relationship with the missing girl case, and was killed by Hao Ming's accomplices?

This series of inferences was clear and reasonable, which made Shui Bingyu faintly excited.

"Team Meng, we have to go back to Kyoto immediately! I want to see Hao Ming again!" Shui Bingyu said undoubtedly.

The two immediately returned to Kyoto by boat and came to the Kyoto City Psychiatric Hospital non-stop.

"Professor Hao. Shui Bingyu called him in front of Hao Ming's bed.

Hao Ming remained half-asleep as always, and after hearing Shui Bingyu's voice, he still closed his eyes slightly and hung her there for five minutes.

"You sit. He finally spoke, "Your patience is getting better and better, and once again I am not wrong." ”

"Do you know Wang Xiaoming?" Shui Bingyu sat down on the chair next to the bed.

As Shui Bingyu expected, Hao Ming didn't answer directly, but just said, "Why do you always ask me like a prisoner?"

Shui Bingyu said: "Why do you think you are a criminal? Could it be that you are a thief with a weak heart? Otherwise, how can you think that I am like a policeman?"

Hao Ming was speechless, and after a while he said, "Since you are not a policeman, I am not a prisoner! I won't tell you anything unless you promise to tell me something that you fear the most!"

Shui Bingyu stood up and said, "Why should I accept such an unreasonable request from you? Even if you don't tell me, I will definitely find out for myself! Goodbye!"

However, Hao Ming's emotional intelligence seems to be very problematic, sometimes he is too shrewd to hit the nail on the head, and sometimes it is as simple as a child, he hurriedly said: "Don't go! You go to the nurse and look at the record of five o'clock in the afternoon, there is a sentence I left there." After reading it, you can decide whether to agree to my request or not!"
