"Zheng Zhi, when are you coming to Arrow Mountain?" Xue Yuanjian asked on the phone.

"This afternoon, the specific time depends on the itinerary of the experts of the provincial department? Yuanjian - is there a 'new' situation? Zheng Shimin said with concern.

"It's not a new situation. I've been working around 'Wang Daquan' for the past few days, and I have some ideas - I can't explain it clearly in a few words. Shall I take a pinch of it? Waiting for you to get to the command - to report to you in person?! "Xue Zhi's words - with complicated thoughts?

"Good! Are you - hard work?! Zheng Zhi hung up the phone with satisfaction:

He admired his deputy - thoughtful, interrogated, and very "political" ...

At this time, Xue Yuanjian had just left the horseshoe slope - to the institute - -

In the early morning of the 15th, Wang Daquan, the "No. 2" who was basically ruled out of suspicion of being involved in the case, was released on bail and returned home.

According to the overall deployment of the project headquarters, Xue Zhi took Xiao Ning to continue to "attack" Daquan, hoping to harvest more valuable clues to solve the case from his memory? And not just a nonsensical "black-coat man"?!

To call Zheng Zhi, Xue Yuanjian has visited Wang Daquan three times in the morning of the 16th, at night and on the morning of the 17th:

The two sides were very reluctant?!?

In the first conversation, Xue Zhizhong focused on eliminating Daquan's resistance to the detective. spare no effort to care about his life security and physical health; Inquire about his interpersonal and family relationships, especially the depth of his relationship with his remarried mother; Is it possible for him to get married and start a family? By the way, explain the reasons for taking him to the police station for investigation on the night of the 14th?

Daquan's reaction was very wooden, basically what Xue Zhi asked - following Xue Zhi's meaning "what to answer", neither taking the initiative to speak, nor saying much.

His underlying meaning is obvious: if you detectives don't "bother" me, I'll do it—thank you; I don't need these "fake" tricks; Even the house was "copied" - what else is there to discuss...

On the night of the 16th, Xiao Guang was present. Xue Yuanjian's original plan was to further relive the scene - the two suspicious "second half of the night" narrated by Daquan; Look at him in person - can you recall more details about that time, especially about the "man in the black coat"? Is it possible for Xiaoguang, who lives next door, to be "confirmed"?

How do you know that Oizumi leaned on the head of the bed and said sharply - "I engage in 'nerve' nagging, I want to go to bed early", "I drip farts - strands - is it clean?" Xiao Guang knows - you ask 'Xiao Guang'".

Daquan pointed the finger at Xiao Guang, ignoring Xue Zhidi's request at all, making the scene ugly?!

Xue Yuanjian didn't know that Xiao Guang leaked secrets after drinking; Wang Daquan has already regarded Xiaoguang as an "enemy".

According to his analysis, Daquan's mood fluctuated greatly, indicating that the ideological struggle was fierce and that there must be a secret hidden with weight. You have to be patient yourself - squeeze "it" out ?!

Xue Zhi and Xiao Ning were walking on the machine farming road on the west side of the waste well at night, and he suddenly stopped - asked Xiao Ning to turn off the flashlight, and then looked carefully in the direction of Daquan and Xiaoguang's houses...

"Hmm-meow-" A cat's meow startled Xiao Ning!

Xiao Ning held back—darkness and strange noises, and stood uneasily close to Xue Zhi: What is he looking at? Pitch-black black (black light blind fire) drops?

"Let's go back." Xue Zhi said for a while--seems to have made up his mind-what's your idea?!

This morning I came to look for Oizumi, and it was the third time.

Xue Yuanjian saw from afar that the door was not opened: Haven't gotten up yet? Oizumi won't have an accident, right? After all, he has been "sick for a long time"?

"There's a note—" Xiao Ning snapped-eyed:

"- On the door..."

"Be quiet—go, go to the door—and see?" Xue Zhi also vaguely saw "a piece of white" on the door, and reminded the young man:

Young is good! When he joined the police, his eyesight in both eyes was above 1.8, and he stayed up all night to read the papers all year round - now his eyesight is much worse...

An exercise book paper, glued to the door panel with leftovers, someone wrote a few lines with a blue ballpoint pen - and the whole is just right:

Dear Leaders,

Hello!

I guess you'll come back to me again? I didn't run!

I didn't do anything unreasonable! It also has nothing to do with the white bones in the waste well!

Why should I run???

I went to the surrounding village to collect the rags, and everyone liked me to collect them. I'm going to live on it, too!

I won't come back at noon, so I can't delay my work!

I'm in the house at night, and if you want to find me, just come!

Leave a note for instructions

Wang Daquan on the same day

"Hey-that's not bad-" Xiao Ning said--about to reach out and uncover—

"Don't move—stay!" After Xue Zhi stopped - fine product:

Daquan's strips are not only appropriate in style, clearly organized, focused, concise and clear; And the layout is reasonable, the handwriting is thorough, the punctuation is accurate, and the pen is through the paper!

Analysis from one's own knowledge of handwriting psychology —

If Daquan is not poor and frail, and has a bad record of "stealing", he would be more than enough to be a township or village clerk with this piece of paper to "explain".

But who can give him such a chance? He's been labelled "bad" – no one cares what he's been through; Even years later, he died - no one noticed that "he had been here"...

Xue Yuanjian suddenly realized that he was thinking too much?!

Although he does not believe that "everyone has his own destiny - no one can be forced", "sometimes fate must be there - fate is not forced at all times", but also believes in "man - determination - victory - heaven", "detective hunt murderer - good is great"; He was still affected by Daquan's note - it caused a lot of emotion!

Xue Zhi carefully observed Daquan's house, abandoned wells, shacks, and machine farming roads, and recalled with his heart the "midnight - seeing 'ghosts'" described by Daquan, and a "detective experiment" plan slowly formed in his mind......

On the afternoon of the 17th, Xue Yuanjian reported to Zheng Zhi, who accompanied Lao K and Wang Lao to the headquarters, the plan of "doing reconnaissance experiments in the second half of the night".

Zheng Shimin discussed with the money bureau and decided: agree - experiment!

It turned out that the in-depth focus of the task force command on Daquan was "whether the black-coated man really exists". Is it really unconvincing to rely on Wang Daquan's one-sided words?

What Xue Zhi pondered for a few days was how to distinguish the authenticity of Daquan's description?

He checked the calendar, and the date of Fenzi's disappearance was the twenty-third day of the lunar calendar: the moon would rise in the middle of the night and set at noon the next day.

Today is the 26th lunar calendar, and the moon rises a little later in the night.

However, the general environment of the moon is still relatively close to that night, that is to say, after removing the difference in cloud cover and other factors that night, the visibility in the second half of the night is basically the same, and the time interval is about 100 minutes.

Xue Zhi plan - let Xiao Ning wear different colors of clothes from light to dark, walk back and forth many times in the moonlight, and the activity route is "waste well shed to machine farming road"; At the same time, Daizumi was asked to stand in the corner of his house at different times and look around, and say the results of his observations, "whether there is anyone and what color of clothes they are wearing."

Through this repeated detective simulation experiment, to verify the authenticity of the "existence of the black-coated man"?

After Xue Yuanjian and the others got the approval of the leaders, they immediately rushed to Daquan's house—

Wang Daquan went out to collect the rags - he returned with a full load, and he happened to arrive home, and he looked in a good mood!

Xue Zhi bluntly said the "second half of the night - request" to him, and Daquan unloaded the car - while agreeing:

"Okay! I'm 'the truth', and if you do an experiment, you can prove that I'm not lying! ”
