Turn the hour hand back slightly.

After coming out of Fang Qing's house, Xia Liang fell into a mental predicament.

Based on his interrogation experience, there were strange things about Fang Qing's confession and alibi.

This was very different from what he expected. He didn't want the mother and daughter to have anything to do with the murderer.

He felt distraught.

Especially thinking of the two footprints left in the cold storage by my brother-in-law last night. Xing Guangkun saw it, and he had to peel him off and show it to the public.

"Lao Xia, what do you think, you are driving." Zhao Gang saw that he had been absent-minded and a little depressed.

Xia Liang still didn't speak. He let go of the steering wheel, threw the notes in his pocket into Zhao Gang's arms, and opened the car door directly.

"You can drive the car back to the bureau and report it yourself."

"Hey, why are you going?"

"I'll go to the cold storage to take a look, I have something to explain to Team Xing."

Xia Liang decided to confess and be lenient. Walking from the Fu'an community to the seafood market, the distance is less than a kilometer.

"No, I don't have a driver's license! Adong, do you have a driver's license? Hey, Old Xia! ”

"You're already a mature cop, figure it out for yourself."

Xia Liang ignored Zhao Gang who looked helpless and left.

In front of the cold storage was Xing Guangkun and his entourage, who were busy. The door of the cold storage was closed, and Xing Guangkun was talking on the phone outside.

Xia Liang stepped forward, but before he could speak, Xing Guangkun had already seen him.

"Xiao Xia, how is your on-site investigation over there?"

Xia Liang was stunned.

"There is nothing suspicious at the scene, but Fang Qing's confession...... It's a bit vague. ”

Xing Guangkun nodded, Xia Liang hesitated slightly, moved his mouth, but heard him say again:

"I'll talk about it later, I'm busy right now. If you want to study the site, pull the door and go in, and the big guys are still inside. ”

Xia Liang answered blankly, and was about to go to the cold storage as he said. As soon as he dragged the doorknob, he was pulled by Team Xing again.

He took off his heavy down jacket and stuffed it into Xia Liang's arms.

"If you don't wear clothes, you won't be cold."

Xia Liang was stunned and said thank you. Xing Guangkun had already brought the phone to his ear and waved his hand at him.

Xia Liang walked into the cold storage and really saw seven or eight criminal policemen wearing gloves and shoe covers running around.

Lao Lin is also in the investigation team here.

"Xia Liang, come here and help."

Lao Lin asked him to help push the shelf that was originally used to block the door, and three or four people pushed the shelf to the cold storage door together.

Another detective lifts the plastic box containing the fish and places it on the shelf, so that the box is suspended between the shelf and the door.

Xia Liang asked:

"Are you restoring the scene of the secret room?"

"Yes," Lao Lin exhaled:

"I can't figure it out. You said that this trick is not difficult to understand, just like the principle of elementary school students putting powder on the classroom door to tease their classmates - this shelf blocks the door, and the gap is not enough for one person to get through, so you can only push the shelf, and as soon as the shelf is pushed, the box has to fall...... The problem is that this shelf is higher than the door, and the people who come in from the outside can't see the box at all, so they must have to be hit...... Isn't that inexplicable......"

Xia Liang hesitated for a moment and said:

"Actually...... It's not incomprehensible. Because the murderer knew about the box. ”

"Huh?" Lao Lin's eyes widened.

Xia Liang sighed and lowered his voice.

"Actually, in the early hours of the morning, my brother-in-law and I came over to investigate......"

He explained the investigation process of staying in the cold storage overnight at the instigation of Zhu Ansheng to the criminal police officers present, including Zhu Ansheng's speculation that "the murderer was the one who played the deceased in the first half of the night". After listening to it, several people all had a feeling of seeing the blue sky through the clouds and mist.

"I see...... No wonder you know there's a box on this shelf. ”

"The suspicion that the two suspects did not react when destroying the body can be explained......"

"I'll call right now and ask, and if the two can prove that the deceased offered to put the box up, then there's a good chance that this speculation is true......"

Finding a new direction of investigation, the team members were like a dose of chicken blood and began to get busy again. Xia Liang quietly pulled over Lao Lin:

"When Team Xing came over today, did you find the footprints left by me and my brother-in-law?"

Lao Lin glanced at him and shook his head incessantly:

"Xiao Xia, I've always thought you were quite smart, but now I don't know if you're really stupid or pretending to be stupid."

Xia Liang was puzzled. Lao Lin sighed embarrassedly:

"Not to mention what you think, the old fritters of the Xing team for so many years, when encountering such a big case that is not seen once in a few years, how can they make the low-level mistake of only surrounding the crime scene and not locking the door......

Xia Liang's eyes widened suddenly, and he was surprised.

"You mean...... Team Xing deliberately let his brother-in-law in......"

Lao Lin looked around and whispered:

"Did you see Team Xing when you came over, did he say anything about you?"

"It's not ......"

"Isn't that it! There are footprints left in the cold storage, and the blocking tape at the door is obviously newly pasted, everyone is doing this, and they are not so clumsy that they don't even see this kind of detail, right? In fact, everyone knows it, so don't worry about Lao Zhu. ”

Lao Lin patted him on the shoulder, continued to ponder the clues in the cold storage, and after a while, said casually:

"Your brother-in-law is actually deliberately covering you. He is a private investigator and cannot participate in solving cases in principle; If the murderer's methods are really the same as he speculated, the first credit for solving the case will still fall on you......"

Xia Liang was speechless, stood for a while, and muttered:

"Why did Team Xing do this to his brother-in-law?"

On the surface, he always strictly forbade Zhu Ansheng's actions to investigate the case, and showed no mercy, but in private, he always turned a blind eye to him...... He didn't understand the mystery of this.

The cold storage door opens. Xing Guangkun, who had finished making the call, walked in again to inquire about the progress of the investigation, but he really didn't ask about the two extra series of footprints on the ground.

Xia Liang was a little confused and listened to Lao Lin tell Xing Guangkun about "Xia Liang's speculation". Xing Guangkun made a few more vigorous phone calls and arranged for the police officer at the police station to adjust the focus of the confessions of Zhang Jianhong and Liu Zhongwei during the interrogation.

Xing Guangkun asked Xia Liang a few more questions about the details of this new speculation, and Xia Liang subconsciously replied. After a while, he remembered something again, and proposed to Xing Guangkun the idea of "let the two suspects return to the scene to help awaken the memory".

Team Xing pondered for a moment and said, "It's indeed a way."

Since then, there has been nothing to do with Xia Liang. He roughly explained Fang Qing's confession to Captain Xing, returned the down jacket to him, and left the cold storage.

Walking out of the market, because the white Accord drove Zhao Gang and his party back to the police station, Xia Liang waved at the taxi on the street. Several taxis with empty license plates sped past him without stopping.

Xia Liang was a little puzzled, raised his hand to look at his watch, it was nearly six o'clock, and he was anxious. So he hurriedly walked onto the road and forcibly stopped an empty taxi.

The driver's window rolled down, and the driver craned his neck with a bitter expression:

"Officer, I didn't break the rules?"

Xia Liang was stunned, looked down and saw the police uniform on his body, crying and laughing.

Sitting in the back seat of the taxi, Xia Liang dialed the phone.

"Forensic Doctor Wu, yes, it's me, Xia Liang...... Did you send me an email about what I wanted? Good ......"

The taxi master sat on the driver's seat like pins and needles, drove the car carefully, looking left and right, for fear of violating a little traffic rules, and the speed of the car from beginning to end did not exceed 50, basically picking up all the sets learned from the driving school. The journey of more than half an hour from Huangsha to Tianhe directly made him drive for fifty minutes, looking at the jumping meter, the taxi master was more worried than Xia Liang in his heart.

When I arrived near the Shahe Welfare Institute, the price list showed that the price was 58 yuan. The taxi master was about to say that he should forget the change, but Xia Liang had already taken out a fifty and a twenty.

"Good work. No need to look for it. ”

came to the "Ansheng Detective Agency", rang the doorbell, and in less than a second, the walkie-talkie by the door was connected, and the voice of Zhu Ansheng came.

"Come in."

Xia Liang was a little surprised, turned the handle, and the door was not locked.

The office was still as messy as it had been seen at the beginning, but there was no smell of rotting food. He walked around the messy cardboard boxes on the floor, picked up the hanger that had fallen to the floor, and heard a voice coming from the back room.

"This way."

He walked inside, and it was Zhu Ansheng's reception room—the only place in the whole room that looked like a person.

As soon as I entered the door, a strong and pungent smell of coffee entered my nose. Xia Liang frowned and looked at the table in the middle.

There was coffee boiling at the other end - Zhu Ansheng didn't even have a normal kettle, so he got a set of flask test tubes out of nowhere and used the alcohol lamp to make coffee directly.

Zhu Ansheng was sitting in front of the workbench in the corner, he turned his head, and the haggard look on his face startled Xia Liang.

A pair of musicians with dark circles under their eyes like death rockers.

"Coffee?"

"No...... I don't like coffee. ”

"Oh."

Zhu Ansheng took off the flask and poured the coffee inside into the cup, Xia Liang noticed that the coffee was as thick as corn paste, and he didn't know how much ground coffee was put in.

He soon found out.

Zhu Ansheng put the flask back on the alcohol lamp, picked up a large bag of instant coffee from the corner, directly opened five or six packets and threw them into the flask, and lifted another one from the ground...... Paint buckets. Pour the tap water into the Molotov cocktail and stir it with a spoon to look like mixing cement.

This curious scene reminds him of the scruffy underground workshop in Fight Club.

Zhu Ansheng picked up the cup and drank the thick coffee in one gulp. His expression was distorted, as if he had drunk horse urine.

"Brother-in-law, you're going to die if you drink coffee like this."

"I need enough caffeine and sugar to sustain my thinking."

"You haven't slept since you came back from the cold storage this morning?"

"Hmm."

Zhu Ansheng sat back on the chair by himself, Xia Liang stepped forward and saw a drawing in front of him, which was a hand-drawn cold storage plan.

It seems that he is still working on the method of cracking the double chamber.

Although he had personally cracked the murderer's method of creating a secret room inside the cold storage, based on a certain intuition, he always felt that the murderer was not a gang, and if it was not a gang, how to restore the cumbersome shelves to the appearance of a secret room after destroying the corpse has become a key problem.

And inferring from the wastepaper basket full of waste manuscripts, Zhu Ansheng has maintained such a state of thinking for a whole day.

"Brother-in-law...... I think it's better for you to take a break. ”

"When you wake up, your brain tends to ignore some inconspicuous clues." Zhu Ansheng said lightly:

"Maybe I've overlooked something right now...... Certain blind spots. ”

The pen in his hand turned around a few times, and he looked up.

"Let's not talk about that. Tell me about what you learned from your investigation of the confessions of the mother and daughter. ”

When Xia Liang heard this, he hesitated for a moment, and then told Zhu Ansheng about the alibi at Fang Qing's house.

Zhu Ansheng listened silently, and when he heard it, the expression on his face became worse and worse.

Speaking of the details of asking Fang Qing for the movie ticket stub, Zhu Ansheng suddenly interjected:

"Where do she put her movie ticket stubs? Drawers? Or somewhere else. ”

"It was taken out of the pocket of a trench coat." Xia Liang asked, "Is there any problem?" ”

"Normal people don't deliberately keep ticket stubs after watching a movie, and it is the most reasonable place to put them in a pocket or something. But if the suspect deliberately created an alibi, he may have kept the ticket in a place where it is not easy to lose, such as a drawer or safe. ”

"But," Zhu Ansheng continued, "if even the details of the location of the movie ticket stub were considered by the murderer and intentional...... That's trouble. ”

The pen in his hand unconsciously taps on the tabletop.

"Judging by the murderer's current layout, this possibility is not non-existent, besides...... These alibi certificates provided to you by that woman named Fang Qing ......"

He scratched his hair helplessly:

“…… It's ridiculous. ”
