On the way to the front village of Huaigu Village, Zhao Zimeng made a phone call to Director Zhang, who received a call in the middle of the night and hurriedly contacted the household registration police in the office.

When the car stopped in front of the gate of Huaigu Village Primary School, Director Zhang and the household registration police were already standing at the gate of the school and waiting.

The household registration police led the three people to Rao's house.

Rao's house has no yard, only two bungalows, and unlike other houses, there is no light in front of the house.

It is understood that Rao Glance's younger brother and brother-in-law live in a house, and after Rao Glance moved to No. 117, the owners of the house became Rao Yifeng and his wife - it was in this house that the couple got married.

Rao's parents and younger brother live in the same house.

The household registration police knocked on the door of Rao Yifeng's younger brother, Rao Yifeng's sleepy eyes, and he was at a loss in the face of the late-night visitors.

Zhao Zimeng motioned for Rao Yifeng to speak quietly, Zhao Zimeng didn't want to alarm Rao Yifeng's parents.

"Director Zhang, in the middle of the night, is there anything going on?" Rao Yifeng said.

"These are the public security comrades of the criminal investigation team of the city bureau." Director Zhang introduced the visitor.

"Rao Yifeng, is this key the key on your door?" Zhao Zimeng put a key in the palm of his hand, and at the same time pointed the light pillar of the flashlight at the key, and asked directly.

"How can the key be in your hands, is something wrong with my brother?" Rao Yifeng was at a loss.

"Rao Yifeng, answer my question first." Zhao Zimeng said.

Rao Yifeng picked up the key from Zhao Zimeng's hand, walked out of the door, closed the door, and then inserted the key into the lock hole, twisted it, and the door opened.

"It's the key to my door." Rao Yifeng said.

"Rao Yifeng, thank you for your cooperation, I'm sorry to disturb you late at night. Here we go. Director Zhang said.

Rao Yifeng motioned to his wife, who was woken up, to continue sleeping, and then put on his clothes and sent the four people to the intersection.

He wanted to inquire about something.

The police came late at night, holding his brother's key in his hand, Rao Yifeng was shocked and scared.

"Director Zhang, is something wrong with my brother?"

"Rao Yifeng, the former village of Huaigu Village was demolished, where does your brother live now after moving out of No. 117?" No one answered Rao Yifeng's question, and Zhao Zimeng simply threw out a new question.

"Our house is too small, and after leaving Professor Cai's house, my brother slept at the house of colleagues and friends." Rao Yifeng's heart was up and down.

"Your brother bought a house in Jiasheng Flower Garden in the south of the city, do you and your parents know?" Zhao Zimeng asked one after another.

"Buying a house? How is this possible? People like us, if they want to buy a house, they can only wait for the next life. Rao Yifeng couldn't believe the sudden news.

"When you got married, did your brother Rao give you tens of thousands of yuan?"

"Yes! That's what he's been saving for years. ”

"As for your brother's matter, we police are not in a position to tell you now, so you'd better not make it public. Sorry for the interruption, thank you for your cooperation. Zhao Zimeng didn't explain too much to Rao Yifeng.

Several people turned around and strode towards the entrance of the school, leaving Rao Yifeng standing at the intersection stunned.

After that, Zhao Zimeng and the three of them went to the Zhongguan grain depot.

Coincidentally, tonight, it happened to be Director Zhou's night shift.

Director Zhou led Zhao Zimeng and the three into Rao Glance's office, and Rao Glance is now a leader of more than 30 people, and finally has "leadership treatment"

Zhao Zimeng used one of the five keys to open the drawer of Rao's desk.

Director Zhou said that Rao also has a wardrobe. There is also a key to the wardrobe.

Finally, Director Zhou found a key in the corner of the drawer of Rao's desk.

Director Zhou used the key to open Rao's wardrobe, and in addition to two sets of work clothes, there was also a military coat in the wardrobe.

At seven o'clock the next morning, Zhao Zimeng, Ling Hu Yunfei and Xiang Daimo went to Hoop Bucket Lane.

It was Cai Yaohua who came to open the door of the hospital.

Professor Cai was in a bad mental state during this period because of his son's affairs, and his daughter Yaohua was not at ease, so she has been living in Hoop Bucket Lane to accompany her parents these days.

She went to work during the day and returned to Hoop Barrel Lane at night to take care of her father.

Aunt Cai and her daughter led the three of them into Professor Cai's bedroom.

Professor Cai had already put on his shirt, and when he saw someone coming, he was about to put on his pants, but he was held down by Zhao Zimeng: "Professor Cai, you don't have to get up. Sorry to bother you early in the morning. ”

Zhao Zimeng leaned Professor Cai against the bed frame.

Cai Yaohua moved three chairs and asked the three of them to sit down.

After not seeing him for two or three days, Professor Cai looked very haggard, and Aunt Cai's expression was also very melancholy.

The old couple has aged a lot all of a sudden, and it seems that Cai Yaohui's incident has hit them a lot.

Zhao Zimeng felt the need to let Professor Cai and his wife know something.

From beginning to end, Professor Cai and his wife gave a lot of help to their comrades.

"Professor Cai, after our investigation, Cai Yaohui has nothing to do with the case of Ion Mountain. The second elder can relax. Zhao Zimeng said.

Professor Cai straightened up, a little excited: "Captain Zhao, my son Yaohui really has nothing to do with the case?" ”

"Yes."

"Have you found the murderer?"

"We're here to tell the second elder that we've found the real culprit."

"Who's the murderer?" Cai Yaohua on the side asked.

"Rao at a glance."

"Huh? The murderer is Xiao Rao? Professor Cai's eyes widened, and he couldn't believe it.

"You can't be mistaken! Can Xiao Rao do such a big case? ”

"I really didn't expect it, this is really knowing people and not knowing their hearts." Aunt Cai said.

"Captain Zhao, who is the person who sold the cultural relics to Yaohui?" Professor Cai asked.

"It's also a glance."

"Since it's Rao, my son Yaohui should know him!" Professor Cai did not know much about the case.

"Rao glanced at the transaction between him disguised as an elderly man and Cai Yaohui."

"Does he still have the skills? We really underestimated him. ”

Zhao Zimeng took out a transparent plastic bag from his leather bag, and there was a copper key in it: "Professor Cai, Aunt Cai, do you still know the key to the door of No. 117 Rao's room?" ”

Professor Cai took the key from Zhao Zimeng's hand and looked at it carefully for a long time.

"How?" Zhao Zimeng said anxiously.

"I can't remember. Look at the old woman. ”

Aunt Cai took the key from Professor Cai's hand, looked at it twice, and then shook her head: "I'm getting older, and my memory is getting worse and worse - after moving, we threw away all the keys to No. 117." ”

"We have lived in the back village of Huaigu Village for so long, and when we moved in, we asked Yaohui to replace all the door locks with new ones. Why can't I remember what hangs on my waistband every day! "Aunt Cai blames herself very much.

In life, the more often you have something in your hands – or what you always see – the easier it is to forget it when it comes to the critical moment. This is the best annotation for turning a blind eye!

"Captain Zhao, let me see." Cai Yaohua stepped forward.

According to Rao, this is the key to his door 117. We're here to find out if he's lying. Zhao Zimeng said.

Cai Yaohua picked up the key from his mother's palm: "Captain Zhao, I also lived in that wing, and that was before the surname Rao moved in. Sometimes, when my dad was not feeling well, I would stay in that room for a night or two. ”

Cai Yaohua took the key in his hand and looked at it again and again, thinking hard.

Zhao Zimeng, Ling Hu Yunfei and Xiang Daimo were all waiting for Cai Yaohua's answer.

"Captain Zhao, in my impression, the key to that wing room is a little smaller than this key." Cai Yaohua said as he turned around, "Captain Zhao, wait for me, I'll go home." ”

"Do you still have the key?" Zhao Zimeng already understood what Cai Yaohua was going to do.

"The key to the courtyard gate and the key to the wing room are on a key chain, I usually don't like to throw things around, I'll go back and look for it, it should still be there. Captain Zhao, isn't this key very important? ”

"Very important. This key is the key on the key chain of Rao, who bought a house in Jiasheng Garden last year. Zhao Zimeng nodded.

"He has a house to live in, why did he run to No. 117 to rent a house?" Cai Yaohua wondered.

"This person is not what it seems, we didn't find anything in Jiasheng Garden, we suspect that he has something else to hide, if this key is not the key to the East Wing of No. 117, then they must be-" Ling Huyun Fei said.

"I see. Captain Zhao, wait a minute, I'll come when I go. Cai Yaohua instantly understood what Linghu Yunfei was expressing, and turned around and left.

"We'll take you back in a car and we'll send you back again." Linghu Yunfei said.

"Okay."

"Please wait a moment, Professor Cai, you haven't changed the locks since you changed the locks, before you moved out!" Zhao Zimeng stopped Cai Yaohua.

"Didn't change. The locks exchanged by Yaohui are all the most expensive locks, and the quality is very good, and the people who sell the locks say that they will not be broken in ten or eight years. Professor Cai said.

"Now that Huaigu Village is being demolished, I want to know if there is any special mark on the room in the east wing that Rao Glance rented?"

"The door was red lacquered, and there were three stainless steel hooks nailed to the back of the door to hang clothes. The team is right, there is a couplet on the door, which was written by Mr. Cao, and the content of the couplet is 'thousands of spring breeze willows, 600 million Shenzhou Shunyao'. Professor Cai said.

Zhao Zimeng, Ling Hu Yunfei and Xiang Daimo bid farewell to Professor Cai and his wife, and walked out of Hoop Bucket Lane with Cai Yaohua.

Aunt Cai sent the three of them to the entrance of the alley.

Ten minutes later, the car stopped in an open area outside the gate of the hospital dormitory.

Cai Yaohua jumped out of the car and rushed into the gate, followed by Zhao Zimeng and Ling Hu Yunfei.

Walking to a building, Cai Yaohua said, "Captain Zhao, you are waiting downstairs, and I will come down in a while." My house is on the sixth floor. ”

Cai Yaohua rushed upstairs, and as she went upstairs, she took out the key from the hanging bag.

There was a flower bed downstairs, and Zhao Zimeng, Ling Hu Yunfei and Xiang Daimo stood by the flower bed and waited patiently.

Footsteps from upstairs were heard "Oooo

After a while, the two men heard the sound of the door opening.

After five or six minutes, there was a loud sound of the door closing from upstairs, and Cai Yaohua walked to the railing and said loudly: "Captain Zhao, I found it." ”

She waved as she spoke, holding a keychain in her hand.

This was followed by the sound of hurried footsteps of "Oooo

The three of them stepped forward.
