The weather in Tanigawa City in June is really like a child's face. The sky was still clear in the morning, but just after the afternoon, a shower suddenly came.

Every noon, there will be a lot of people in the ancient alleys of western Sichuan, but there is silence at the moment. Those who rubbed hemp and drank tea had already gone into the alley and built a shed storefront. While dusting their wet hair with their hands, they talked to the boss to take the opportunity to avoid the torrential rain. Occasionally, three or two hurried figures appeared in the alley, and most of them disappeared into the rain in a flash.

As a commercial street with a history of nearly 100 years in Tanigawa City, the ancient alleys of western Sichuan not only attract many foreign tourists, but also those locals who mingle here all year round to drink tea and play cards. These locals are also often nicknamed "skins".

A Grand Cherokee sped from a distance with its shiny headlights, and the splash of water from the wheels looked crystal clear in the light of the headlights. Sun Meng sat in the car and held the steering wheel with both hands, staring at the slightly muddy road ahead with an expressionless face. In the co-pilot seat beside him was a bouquet of delicate lilies and a bag full of cold pure beer.

It is Sun Meng's intention to bury Su Ruo in the crane cemetery at the northern foot of Jishou Mountain.

The Crane Cemetery has beautiful scenery and is quiet and pleasant, which can not only make Su Ruo, who has exhausted Shaohua but full of police might, sleep quietly; At the same time, it is also the closest place to the Tanigawa City Welfare Center, which he once wanted to spend his life protecting.

Sun Meng parked the car, picked up lilies and beer from the co-pilot's seat, and a flock of white doves flew in the drizzly sky. He walked quietly on the moss-covered stone path in the cemetery, climbed the stairs through a low-hanging willow forest, and Su Ruo's tombstone appeared in front of his eyes.

Sun Meng stared blankly at the photo on the tombstone. In the small picture, Su Ruo is dressed in a police uniform, chic and handsome. The figure is smiling, as if delighted by the arrival of an old friend. Sun Meng raised his hand and rubbed his nose, gently put the bag of beer in his hand at his feet, walked forward with only the lily, and carefully and solemnly placed the flowers in front of the tombstone. Then, he took a few steps back and bowed deeply towards the tombstone.

After the rain, the air in the Crane Cemetery is filled with the fragrance of earth.

Sun Meng got up and walked back to the tombstone slowly, stretched out his left hand and gently stroked the line of small words engraved in the upper left corner of the tombstone, "The eternal pride of the Tanigawa City Welfare Institute". Tears began to roll in his reddened eyes.

Under the tombstone, the dragon pillar engraved with "Sun Meng, Guo Tanya Jingli" was wiped almost spotlessly. Sun Meng knew that Guo Tanya had been here.

"Old Su!" Sun Meng gently scraped away a tear falling from the tip of his nose with his thumb, turned around and sat on the steps next to the tombstone, stretched out his hand to open the two listening to Bingchun, and put one of them in front of the tombstone.

"After the murder case in Jingnan last time, my brothers and I have never drunk together again. I know that you love to drink ice pure, you see that my brother is in his pocket, today, I will give you enough beer! Sun Meng touched the beer in his hand lightly with the beer in front of the tombstone, and poured a big sip as soon as he raised his head.

The drizzle of rain was dripping down on his face, and he tilted his head and squinted, greedily breathing in the air from the rain.

"Lao Su, do you remember when I was a child in the welfare home, the first day Tan Ya and I were brought by the dean, I had a big snot all over my body, and I was dirty like a mud monkey. The other children were hiding on the side and looking at us from afar, only you ran over and took me and Tanya's hands, held your chest and said call you Brother Su Ruo, you can protect me and Tanya. Speaking of this, Sun Meng took another sip of wine, lowered his head and smiled.

"Later, I was stupid enough to sneak over the wall with you and go to Longhua to buy marshmallows. On the way back, I was holding such a big marshmallow and drooling, and you told me that if I could keep the marshmallow from falling to the ground on the way, you would let me eat half of it when I came back. I was cautious and frightened along the way, for fear that the marshmallow would fall to the ground and my hands would be tired. You're good! As soon as I came back, I immediately gave it all to Tanya alone. ”

"I don't blame you! You spoil Tanya, am I too? Who called us all brothers? ”

The wind blows up the willow leaves that cover the sky, and the melodious pigeon whistle echoes in the quiet crane cemetery in the valley not far away.

"I still remember that year when we were at the police academy, there was a crime scene investigation class, and Professor Gong Yansong, a criminal investigation expert from the Ministry of Public Security, took us to reconstruct the crime scene. At the scene that looked like a suicide, everyone was talking and arguing. You are the only one who can see that the criminal has used a simple mirror principle to forge a secret room to help him complete the killing. Professor Gong was full of praise for you at that time, saying that you will definitely be the white jade pillar of the criminal investigation world in the future, and you will be the purple gold beam of the sea. ”

Sun Meng stretched out his hand and gently flicked the lilies in front of the tombstone, and continued to whisper in his mouth: "What about you?" Hehe smiled, saying that there is no perfect crime in the world at all, as long as it is a human being, it will definitely leave clues. Those so-called perfect crimes are just the details of the scene and that are overlooked by our police. I can't remember what you said later, but it was this sentence that was engraved in my heart that I still remember today. ”

"Hey," Sun Meng took a sip of wine to herself, and a wry smile slowly appeared on her face, "You always say that you especially want to solve a locked room murder case in person, which is not only exciting but also very challenging." But it's a pity that with the IQ of the criminals you have competed with in reality, no one can complete the wonderful crime process in detective novels. ”

Speaking of this, Sun Meng suddenly paused for a few seconds, drank the remaining beer in his hand violently, and clattered the empty can.

"Walnut Ridge died yesterday a university professor who studied medicine, and the scene was greatly exceeded. According to the preliminary inquest at the scene, the opinion given by the medical examiner was suicide. I disagree, but I really can't find any evidence. I've been so anxious and sleepless at night for the past three or four days, but by this time your brother has slept peacefully here. ”

Sun Meng stood up and brushed his wet hair, opened the few remaining beers and poured them around Su Ruo's tombstone. In the distance, the sound of dove's whistle was heard in the valley.

The warm rain gradually stopped. A thin layer of water mist hung over the windshield of the Grand Cherokee. Sun Meng, who returned to the car, put on sunglasses and turned on the wipers.

Not far in front of him, a cemetery sanitation worker wearing a mask, dressed in blue, and carrying a broom and dustpan on his back limped over with the lily that Sun Meng had just left in front of Su Ruo's tombstone.

Sun Meng frowned, but his eyes caught a glimpse of the sign advocating environmental protection sacrifices next to him. He smiled self-deprecatingly and started the car to leave. At that moment, the screeching ringtone of a mobile phone pierced the silence around it.

As soon as Sun Meng answered the phone, Gu Xiang's broken gong voice roared hoarsely: "Meng team!" Where are you in the Moe team?? Hurry back to the bureau!! ”

By the time Sun Meng drove back to the Guchuan City Public Security Bureau, it was already three o'clock in the afternoon. Gu Xiang, Zhang Zhichao and Li Suqing were already waiting there in the morning. Gu Xiang watched Sun Meng being drenched in the rain and hurriedly stepped forward to ask.

"It's nothing," Sun Meng waved his hand, turned around and locked the car door. He stroked his half-dried hair with his hand as he walked towards the forensic center.

"I just went to see Lao Su."

Several people couldn't help but be stunned when they heard this, and then fell into silence. Sun Meng raised his head and looked at them with a faint smile: "You are in such a hurry to call me back, is there any breakthrough in the case?" ”

Before a few people could answer, a heart-rending cry reached the ears of Sun Meng, who had just walked into the hall on the first floor of the forensic identification center.

"What's going on?" Sun Meng looked back at everyone in surprise.

The humble Zhang Zhichao touched his head and muttered in a low voice: "Brother Kai is back." ”

"Zhou Kai?"

"We don't know what's going on. Brother Kai was very happy when he came back at noon, and told me that the treatment of a business trip in the province was good. Later, I heard that Dachao was doing an autopsy, so Kai Ge came over to help. However, listening to Dachao, it seems that Brother Kai just glanced at the corpse and cried bitterly. We rushed over and couldn't persuade us. ”

After listening to Li Suqing's words, Gu Xiang nodded and continued: "Later, Dachao invited Uncle Li, Uncle Li pulled Brother Kai and talked for a while, but Brother Kai just begged Uncle Li over and over again to give him justice. ”

"Zhou Kai, this is? … Well? Sun Meng frowned and twisted her chin slightly. Suddenly he patted himself on the head, "I remembered!" This deceased He Shipeng seems to be Zhou Kai's teacher in college! ”

Hearing Sun Meng's words, several people also suddenly realized. They all said that it seemed that they had indeed mentioned this name when they heard Zhou Kai chatting with them before.

"Quick, you go and call Zhou Kai to me, I have something to ask him!"

After a while, Zhou Kai followed Gu Xiang and Li Suqing to Sun Meng. Sun Meng saw that Zhou Kai was crying with red and swollen circles under his eyes, he sighed softly, and stepped forward and patted him on the shoulder in distress.

"Meng Team..."Zhou Kai's voice was hoarse, and his voice sounded weak.

"The deceased... You used to be a teacher, right? ”

"Hmm."

"You've also seen the results of Dachao's initial inspection, right?"

"Look..."

Before Sun Meng could speak again, Zhou Kai suddenly began to sobble again: "Team Meng, teacher, he must have committed suicide..."

"What about motivation?"

"The teacher is kind-hearted and kind to others. Moreover, he was quite confident in his medical skills and scholarship during his lifetime. However, during an orthopedic operation last month, the teacher's judgment of the patient's state during the operation caused the patient's secondary bleeding. Although there were no sequelae left for the patient in the end, it did make the patient suffer a lot. After that, I met with my teacher a few times, and when he was chatting with me, he would say something like 'it's over, it's over', 'It's better to ruin my reputation than let me die.'" I heard that the patient's mother seemed to be a media reporter who was quite influential in Tanigawa City. ”

Sun Meng listened to Zhou Kai's words, raised his hand and began to gently twist his chin again.

"Yo! Old grandson! I'm going to look for you! ”

Li Yingbo, who had just finished He Shipeng's second autopsy, happened to come over.

"Thank you Lao Li, is there anything new to discover?"

Li Yingbo nodded and said: "I just conducted a second autopsy on the deceased, and not only alcohol and over-concentrated aspirin were detected in the remains of the deceased's stomach. The presence of odorless erythromycin was also found. ”

"Really?"

"Yes, as you think. During the autopsy, I also found that the deceased had an enlarged liver and spleen, cholestasis, and the presence of jaundice. ”

"Awesome Lao Li! It's time to file a case! Absolute murder! Sun Meng nodded excitedly and looked around at everyone: "These evidences are enough to show that the murderer clearly wants to put the deceased to death!" ”
