Whenever a gust of wind blows, the willow trees will scratch their heads and make a "rustle" whisper.

In the blink of an eye, Tanigawa City is in full swing again in July.

Capturing the fleeting coolness of the morning will be very comfortable for both people and dogs.

In the past month, Guo Song has gone to the newly completed Lychee Park in the community every day after breakfast. Since the death of his wife half a year ago, his life has suddenly become empty.

But it was the chance that a month ago changed his life that had always been monotonous and slightly boring. Now, going to the fitness park to talk to the lonely old lady there has become his daily life after dinner.

Today, Guo Song also had breakfast early as usual. Just as he was about to step out of the house, his whole body suddenly froze there as if it had been electrified. At that moment, he must have regretted the decision he had just made in his mind.

Just outside Guo Song's house, Sun Meng, Gu Xiang, Li Suqing and Li Yingbo were standing there looking at him with a smile.

The door of Room 1302 of the Walnut Ridge Community has long been sealed by the Tanigawa City Public Security Bureau.

After that, several other families on the same floor invariably pasted the rune paper with black letters on a red background high in the center of their lintel. One of the most exaggerated is the 1301 room where Guo Song lives opposite, and a large and exaggerated gossip map is pasted on top of the bright red paper symbol.

There seemed to be an eerie quiet atmosphere in the entire corridor now.

"Hey... Grandchild... Hello Officer Sun. You... You're... How did you get here? Guo Song smiled all over his face, stretched out his right hand and made a "please" gesture to the room, "Few... Several police officers... Well, come in and sit. ”

"Yo? Are you going out of the house? Sun Meng's eyes carefully looked at the room behind Guo Song, and the overall white and blue tone showed a bit of elegance.

"Ahhh I'm just going out and slipping away... Wander around. Digestion and digestion of food. ”

Sun Meng nodded: "We just came here to revisit the scene." Since you're at home, let's find out more about the situation by the way. How's it going, you've been in a good mood lately, right? ”

Since the news spread that He Shipeng died at his home in Walnut Ridge Phase II, the investigation of the entire case has been slow so far. The police's delay in closing the case has put the residents of the community in a state of panic, not to mention the families who lived on the same floor as the deceased.

Therefore, on the night when the body was found, Zhang Lei, director of the Guchuan City Public Security Bureau, had instructed five psychological experts from the Municipal Public Security Bureau, including Chen Yating, to carry out psychological counseling for all residents of the Hetaoling Community together with several doctors from the Psychiatric Department of the Second Affiliated Hospital of Tanigawa Medical University.

"Hey! We have a big heart! We are now well-fed and well-slept every day! You see, we're all this old, and we have experienced a lot of winds and waves when we were young. Once things like this are over, I slowly forget about them. ”

The wrinkles at the corners of Guo Song's eyes were crowded together.

"Hmm!" Sun Meng nodded, "It seems that our beautiful policewoman is more effective than us rough men in this regard!" ”

Sun Meng's words amused everyone present. In the laughter, Guo Song gradually let go of the uneasiness just now, and the whole person seemed relaxed.

"I remember that Mr. Guo didn't stutter when he reported the crime, right?" Sun Meng suddenly put away her smiling face and asked coldly.

This sentence caused the whole room to fall silent for an instant. Guo Song's smile gradually solidified on his face. His face turned red to the base of his neck.

"I... No, Officer Sun..."Guo Song's mouth was staggering, and his two hands kept rubbing his knees back and forth.

Sun Meng immediately smiled heartily again: "Don't be nervous Mr. Guo." Is it easy to use your bathroom? ”

"Ah, it's convenient." Guo Song was relieved.

Although Guo Song's home is opposite to He Shipeng's house, a thick load-bearing wall still connects the bedrooms on the north side of the two families. The bathroom in Guo Song's house is on the hallway that leads through the living room to the bedroom on the north side. A corner with a small arc just right to block the view in the living room.

Sun Meng gently unscrewed the door of the north bedroom. This room is almost 20 square meters and is very simple to furnish. A pair of blue and white porcelain vases, almost a man tall, were clinging to the wall to his right.

Although the windows of the house are facing north, the sunlight reflected on the glass curtain wall outside the window is spilling into the house through the floor-to-ceiling windows in front of Sun Meng's eyes.

What remains in the room is a bogu shelf, with three floors, upper, middle and lower, which occupy almost the entire wall opposite the window. The shelves are filled with all kinds of bottles in different packaging, some with packaging and some with wooden mats. Each layer of wine is placed in exactly the same position and height, looking like a neat group of soldiers.

Sun Meng gently pushed open the screen window probe on the left side and looked out. Downstairs is a parking lot. He twisted his chin and looked back at the neat rows of bottles on the Bogu shelf.

In the living room, Guo Song was still rubbing his hands constantly.

"How big is Mr. Guo's house?" Sun Meng sat back in front of Guo Song with a smile on his face. Gu Xiang and Li Suqing also stopped whispering between them.

"82 flats is about the same."

"Although each of our Walnut Ridge Phase II looks the same from the outside, in fact, the size of each household is different. Even a few families like us who live on one floor are different. For example, like Lao He's house, it's a duplex. And there's a secret door on the side of the fire staircase, right? Guo Song said as he glanced at a quartz clock hanging in the center of the living room.

Although the Walnut Ridge Community is one of the sky-high residential houses in Tanigawa City, the developer has considered that more levels of people can enjoy a comfortable and livable living experience at the beginning of the design. Therefore, they have arranged a relatively inexpensive small house on each floor for people of these levels to choose from.

Guo Song is the first batch of college students after the resumption of the college entrance examination in country M. Thirty years ago, he left his hometown with his bags and came to Pingjiang and entered the university campus in high spirits.

Because he has a good hands-on ability since he was a child, in order to respond to the call of the country, let the intellectual youth go into the factory, so when choosing a major, Guo Song resolutely filled in the mechanical engineering major.

By the time he graduated, it was just in time for the era of bag distribution. With excellent academic performance, he was naturally assigned to the largest heavy industry base in country M at that time - Pingjiang Jianhua Factory. Seven years later, Guo Song became the youngest deputy technical director in the history of Pingjiang Jianhua Plant.

Later, with the change of economic tide, state-owned enterprises were restructured, and Pingjiang Jianhua Factory was transferred to the local government. Tanigawa City established a group by private entrepreneur Shen Ziyi through investment promotion, and Pingjiang Jianhua Factory was renamed the current Pujiang Industrial Group.

The wave of layoffs fell on Guo Song, and the old man, who was getting older, stopped. A large sum of money put an end to his ambition to devote himself to the industrial enterprise of country M.

And the great feats made by this nearly half-hundred-year-old man for the industrial development of country M are now remembered on the little finger that was severed in his right hand.

"Does Mr. Guo often go to room 1302?"

"Ah, I... I occasionally... Not... I've drunk a few times..."Guo Song's eyes began to wander.

Sun Meng gently twisted his chin and didn't speak, and Gu Xiang, Li Suqing, and Li Yingbo also widened their eyes.

"Officer Sun," Guo Song raised his head and asked timidly, "How did Lao He die?" ”

"Killed."

"Ah????h Guo Song sat slumped on the sofa, his face pale.

Sun Meng stood up and motioned for everyone to leave with him. He walked to the door and suddenly stopped: "By the way, Mr. Guo, when you reported the crime, you mentioned that you once smelled the stench that filled the corridor, can you give us a specific description of the smell you mentioned?" ”

"Ahh Sour bar... Or maybe it's rancid..."

..................

The secret door of He Shipeng's house is almost half a person high. The location is below the kitchen cupboards. The first site survey did not find anyone.

Sun Meng stood in front of the secret door and twisted his chin.

Lee Ying-bak is using the tools inside the investigation box to extract traces and physical evidence from the scene again. Li Suqing held a notebook on the side, carefully recording the information that Li Yingbo fed back.

"How about Lao Li? What's new? Sun Meng frowned, squinting at Li Yingbo, who was squatting on the ground and busy.

Lee Young-bak shook his head, and he stood up and took off his rubber gloves.

"Old Sun, I have once again made a careful survey of the center site. There was no bloodstain reaction at the scene, so the cause of death of the deceased was unique. At the same time, I also confirmed that there were no valuable fingerprints or other clues at the scene, including the newly discovered secret door. And there was no physiological reaction at the scene other than the deceased. In other words, it is now almost certain that no one in the house was in or out of the house except the deceased himself during the period before the deceased's death and after the arrival of our police. The expression on Lee Ying-bo's face also looked a little regretful.

"Meng team," Gu Xiang, who had been in the bedroom on the north side, suddenly shouted to everyone.

"I found a hair, white, under the foot of the bed."

Sun Meng held up the evidence bag and observed it carefully. A 3-centimeter-long hair in the transparent bag was nowhere to be seen under the illumination of the survey lamp.

"Team Meng, could it be..."Gu Xiang and Li Suqing's eyes flashed.

Sun Meng didn't answer, but just pushed hard, and the window on the far right side of the bedroom on the north side of 1302 was pushed open. He shook his head: "Impossible, this building is a steel-concrete structure, and this is a load-bearing wall. ”

"For the convenience of the residents, although the windows in this room are on the same wall as the north bedroom of 1301, the windows that can be opened are on the farthest side of the left and right ends. I have to be about 10 meters away from this distance. And this is the 13th floor. ”

Sun Meng said and stuck his head out of the window to look to the left, where Guo Song was looking at him with his head sticking out.
