"Add generation, add generation!"

After entering the house, Zengwei Guizao rushed into the house with the crowd while anxiously shouting his wife's name.

However, when the Party passed the porch and ran to the entrance of the stairs, Zengwei Guizao suddenly stopped, pointed to the stairs leading to the second floor and gave the first command: "two police officers, please go upstairs and have a look. I'll go to the living room."

"OK."

Officer Sato and officer Takaki didn't think much and rushed directly to the room on the second floor, while Zeng Wei Guizao went straight to the living room, opened the door and went in.

Baiyan Zhenyu did not act rashly, but carefully observed the scene in the room and soon made a new discovery.

A window at the corner of the first floor, near the switch, was cut into a regular round hole with tools, which seems to be a trace left by outsiders.

However, Baiyan Zhenyu noticed some details, that is, the window was not opened, and the switch was also blocked.

Just as Baiyan Zhenyu was preparing for further investigation, a sudden change occurred, and the scream of Zeng Wei GUI Zao came out of the living room.

"What happened?"

Hearing the scream, Bai yanzhenyu immediately ran to the living room with Conan. As a result, he found that Zeng Wei Guizao fell down in panic at the door of the living room, trembling and pointing to the living room.

Baiyan Zhenyu and Conan looked at each other. Their foreboding became stronger and stronger. They hurriedly looked into the living room.

In the living room, a woman fell face down next to a pedal sports car used for fitness, with a dagger on her back and a light yellow dress on her upper body, which was soaked with blood.

"What's going on?"

Officer Sato and officer Takaki, who were looking for Mrs. Zengwei upstairs, also ran to the living room after hearing the scream. When they found the woman who couldn't stand up, they immediately ran to check the situation.

Sergeant Sato put his hand on the woman's neck. After a slight test, he shook his head and said to sergeant Takagi, "Alas, Takagi, call the personnel of the mobile search team and the identification section as soon as possible. She's dead."

"Yes."

Officer Takagi immediately informed the police, then looked at his watch and recorded: "the time when the body was found was 12:46."

With tears in his eyes and a sad tone, Zengwei Zao said, "officer, who killed Jiadai so ruthlessly? Do you really mean which robbers?"

"Mr. Zengwei, please calm down. When we find out the results, we will catch the murderer who killed your wife."

Officer Gaomu patted Zengwei Guizao on the shoulder, comforting Zengwei Guizao who lost his wife and waiting for the arrival of police personnel.

After Conan preliminarily observed the scene, he looked suspiciously at the crying Zengwei Guizao, and whispered to Baiyan Zhenyu, "brother Zhenyu, what do you think?"

Baiyan Zhenyu touched his chin, closed his eyes and thought for a while, and said in a deep voice, "I feel something wrong."

"First, why did Zengwei Zao look at his watch several times in a row in the police station? If the first time was to determine whether he was late, what were the next two times?"

"Second, in their previous conversation in the police station, why didn't Mrs. Zengwei know that the time was changed to five o'clock?"

"Third, the body is in an obvious position in the living room. It is reasonable to say that Zengwei Guizao should have seen it the moment he opened the living room? Why did he make a startling cry after dozens of seconds?"

"Fourth, Mrs. Zengwei was on the phone at that time. Generally speaking, the killer should wait for her to hang up before attacking, so as to avoid exposing her voice due to accidents."

Baiyan Zhenyu's analysis was justified, which made Conan agree, nodded and echoed: "yes, I suspect this is a murder case, and the murderer is likely to be the Zengwei Zao."

……

Before long, the police officers of the mobile search team and the identification section rushed to the scene and officially began the on-site investigation.

"The murderer was named Zengwei Jiadai. He was 42 years old. The murder weapon was a dagger stabbed into the center of Mrs. Zengwei's back. The dead didn't find any signs of struggle. It seems that he was killed by the murderer."

After the results of the on-site investigation came out, officer Sato looked at Mrs. Zengwei's body and analyzed it attentively: "I think the time when the gangster committed the murder is probably when the victim made a sad sound on the phone."

After a policeman heard officer Sato's words, he was surprised and asked, "officer Sato, did you hear the victim's mourning?"

Officer Sato nodded. Officer Takagi immediately explained: "the victim's husband just called here from the police station. When they talked, I accidentally turned on the loudspeaker. At that time, everyone heard Mrs. Zengwei's scream."

"I see." the policeman recorded the information and speculated, "so the victim was killed from behind with a dagger while talking."

"Officer, look at Mrs. Zengwei's body."

Bai Yan Zhenyu squatted next to Mrs. Zengwei's body, pointed to the back and arm of the body and said, "after death, people's metabolism will stop, but Mrs. Zengwei's body has a lot of sweat, and she hasn't done it yet. It shows that she must have done something that will make her sweat before she was killed."

Officer Sato brightened his eyes and said in surprise, "Baiyan, what do you mean..."

"That's right," Bai Yan Zhenyu nodded and reasoned, "I've seen it just now. There are no sports shoes suitable for jogging in the shoe cabinet. In addition to her position, there is no accident. At that time, she must be answering the phone while stepping on her bicycle."

"Eh? You're pretty good at it," Sergeant Sato said, looking at Bai Yan Zhenyu in surprise. "It's worthy of being a detective, Mr. Maori's family..."

"Detective Mr. Maori..." after hearing officer Sato's words, Katsuo Zengwei suddenly changed his face and asked tentatively, "is it Mr. Maori Kogoro?"

Baiyan Zhenyu looked at Zeng Wei Guizao with deep meaning, smiled and said, "yes, Maori xiaowulang is my uncle."

Zengwei made a smile on his face and said reluctantly, "ah, it seems that this time it will trouble you."

Sergeant Sato didn't see the difference made by Zengwei. He ordered several other police officers: "you guys, go nearby to investigate if anyone had witnessed the situation at the time of the crime. The rest, and Mr. Zengwei, go to check the property of this house to see if the gangster stole the property."

"Yes, officer Sato."

The police responded. When they were about to act according to officer Sato's order, a voice suddenly came from the door of the living room.
