Early the next morning, Han Yu and Ye Youchen went to Huaihua Road, and the two walked into an old-fashioned building on the street, Ye Youchen said while walking, "The third floor is where I came last time, the old man is a grandmother in her 70s, and her granddaughter is in elementary school. ”

Han Yu nodded and looked at the house. There is no elevator in the house here, at most it is only seven floors, the handrails of the stairs are mottled with paint, and the cement stairs look a little old, but fortunately they are clean. The wall next to it is yellowed, and at first glance you can tell that it is a wall that was painted a long time ago. The two walked to the third floor, Ye Youchen knocked on the door, the door was an old-fashioned security door, it took a long time for someone to open the door, it was a little girl.

Ye Youchen greeted with a smile, "Linlin, do you remember me?" ”

This little girl named Linlin was very happy to see Ye Youchen, probably because of Ye Youchen's help, she finally didn't have to be separated from her grandmother, and replied very enthusiastically, "Uncle Ma, I remember you, you guys come in first, grandma went out to buy something." ”

"Oh, okay," Ye Youchen was not polite, pointing at Han Yu and introduced, "This is my friend, his name is Han Yu, and he wants to come over to find someone." ”

"Hello Uncle Han," Linlin called out obediently, "You sit down first, and I'll pour you tea." ”

Han Yu walked to the window and looked downstairs from here, and he could just see the convenience store diagonally opposite. Han Yu thought for a moment and asked Linlin, who was coming over with water, "Linlin, did you grow up here?" ”

"That's right."

"Are you familiar with the convenience store across the street?"

"Of course, I go there a lot to buy things."

Just when Han Yu wanted to ask, the door opened, it was the grandmother who came back, Linlin hurriedly went over, the grandmother was surprised to see Ye Youchen, but she was still very happy. After Linlin obediently went to do her homework, Han Yu explained her intentions.

The grandmother took the photo of the woman Han Yu gave her, because it was too blurry, she couldn't see her face clearly, and she could only see a figure and dress. The old grandmother thought carefully and said, "Officer Han, my old woman's eyes are not very good, I really can't see anything in this photo you gave." ”

Han Yu continued, "In this way, let me talk about some of her characteristics, you think about it carefully, and see if you have encountered such a person in your daily life, just around here." After seeing the old man nodding in agreement, Han Yu spoke, "This woman is relatively tall, with long hair, and she speaks with a distinct foreign accent. ”

"Out-of-town accent?" The old grandmother interrupted, "What you said, it can't be Chunmei, right?" ”

"Who is Chunmei?"

"Chunmei is a vegetable seller in the vegetable market, I don't know what her full name is, anyway, everyone calls her Chunmei. I remember that she didn't seem to be a local, she spoke with a strong accent, and she sold fresh food at a fair price, so I often went to her to buy food. You see, I just bought it from her. The old woman pointed to the food she had just bought on the table and said, "She seems to be quite tall, but she usually holds her hair and doesn't know how long it is." But I didn't see her wear it like that. ”

The old grandmother held the photo, still very unsure, the woman in the photo was dressed very brightly, and it was completely different from the Chunmei she knew.

"Old man, I'm sorry today, I'll leave first." Han Yu strode out, Ye Youchen was peeling oranges next to him, and before he had time to feed them to his mouth, he could only hold the oranges in his hands and follow him, greeting the old man as he walked.

The vegetable market is less than five minutes away, and the gate says "Huaihua Road Farmers' Market". Everyone knows the people who sell vegetables in the vegetable market, and as long as you ask, you will know where Chunmei is. The two walked to Chunmei's stall, and she was busy.

She is wearing a dark cotton jacket, her hair is pulled up, her skin is rough, but her facial features are not bad, and she is tall, which is still very noticeable. Chunmei thought they were here to buy vegetables, so she smiled and asked, "What are you two buying?" ”

Han Yu frowned, it seemed that it was her, her accent was exactly the same as Cheng Xiuxiu's. "Do you know Cheng Gang and Cheng Xiuxiu?"

As soon as she heard these two names, Chunmei's face immediately changed, and she was silent for a while before asking, "Who are you?" ”

"I'm from the criminal police team, and I want to talk to you." When Han Yu deals with the case, he always gives people a feeling without the slightest emotion, "Do you think you want to talk to me back to the criminal police team, or here?" ”

Chunmei glanced around, and the people next to her didn't know that Han Yu was a policeman, so they all looked at this side with a puzzled expression. Chunmei smiled and said, "Let's go." ”

When the people next to her saw that Chunmei was leaving, they all asked her where she was going.

Chunmei pretended to be casual, "This relative is here, you have to go out for a meal, you guys are busy first." ”

Ye Youchen helped with this, and went back to his psychological counseling room to get busy. When Han Yu and Chunmei returned to the criminal police team, they found that Cheng Xiuxiu was also here. Ye Xiaoxiao sat on the chair and talked to Cheng Xiuxiu, Cheng Jiaxuan and Bai Yifan stood aside, Cheng Xiuxiu saw Chunmei coming, and immediately stood up, Chunmei also looked at Cheng Xiuxiu, the two were only a few meters apart, but it seemed to be very far away. The atmosphere in the office was a little tense for a moment, and Han Yu interrupted, "Lao Cheng, you take Chunmei next door." Xiao Xiao, you take Cheng Xiuxiu to the interrogation room. ”

Several people were stunned for a moment, but quickly did what he said, and surprisingly, Cheng Xiuxiu was very obedient and did not resist at all. When only Bai Yifan and Han Yu were left in the office, he walked over and asked, "Why is Cheng Xiuxiu here?" ”

Bai Yifan shook his head, "She just arrived, just two minutes before you came back, we were also surprised, Sister Xiao Xiao was about to ask, and you came back." ”

"You come with me to the interrogation room."

"Me?" Bai Yifan was a little nervous, what she was most afraid of was entering the interrogation room, and generally those who could enter the interrogation room were either suspects, suspected prisoners, or confirmed prisoners.

"Questions?"

"Nope!" Bai Yifan looked at Han Yu's serious expression, even if there was a problem, he had to swallow it, and obediently hugged the computer and notebook to keep up.

"I'll go to Lao Cheng's side first, you go to Xiao Xiao and tell her that you don't need to talk to Cheng Xiuxiu, let her go to the forensic department and get the report back."

Before Bai Yifan could agree, Han Yu had already left.

Chunmei sat there and didn't speak. Cheng Jiaxuan still can't believe that the person in front of him is the person who walked with Cheng Gang in the video. Two women, one is Cheng Gang's wife and the other is Cheng Gang's lover, is this fire really premeditated? Is the murderer in the middle of these two?

Bai Yifan was also full of doubts at the moment, these two people, both in their 40s, looked like a kind and simple middle-aged woman, no matter how they looked at it, they had nothing to do with killing, let alone killing their closest people.

Han Yu came back from Chunmei's side quickly, and it happened that Ye Xiaoxiao also came back from the forensic department, and when he saw Han Yu, he handed him something in disbelief, "Team Han, you already knew the result?" ”

"On the way back, the Forensics Section sent me a message."

"You found the thing?"

"Well, I thought there was something wrong with it from the beginning, so I went back and carefully examined the physical evidence again, and I thought it was a little strange, so I asked them to check it."

What Han Yu was talking about was the burned and deformed metal object he had found earlier, which read: 17.

The results given by the forensic department are that this is the middle part of the bottle cap, and it is a very famous brand: Guojiao 1573. Because this is metal, it didn't burn for long, so it was just deformed and didn't melt, but the middle number and the back number were burned, so that when I first saw this, no one knew what he was.

Bai Yifan was a little puzzled, "How can there be wine in the kitchen, it's not cooking wine for cooking, and it's such a precious wine." ”

"That's right," Cheng Jiaxuan didn't understand, "I drank wine before, but I didn't finish it, and I put it on the kitchen cabinet casually, and my daughter-in-law scolded me." It is said that in addition to cooking wine in the kitchen, you should not usually put liquor in it, it is more dangerous. So ....." Cheng Jiaxuan didn't finish speaking, he probably knew the situation himself and stopped talking.

Han Yu looked at the interrogation room, and Cheng Xiuxiu sat quietly, as if she was seeing her for the first time, "I'm afraid I have to ask her these questions." ”
