Cao Xiaohui's face was suddenly full of confidence, and then said: "Secondly, this Du Congjun is short of money for business, and has borrowed money from Tan Junhao twice, but Tan Junhao did not lend it to him the second time, so he held a grudge and took advantage of the fact that Tan Junhao had an enemy to come to the door to intimidate Tan Junhao, and wanted to blackmail him. ”

"Your analysis is not unreasonable, but there are still a few doubts in this matter that have yet to be clarified."

Nie Xiaohu nodded and said, "That's it, tomorrow you send someone to find that Du Congjun and that helper at his house, Liu Ma, I have something to ask." ”

"Okay!"

"This is more or less interesting", Nie Xiaohu touched his chin and muttered to himself.

Early the next morning, Cao Xiaohui sent people to Tan Junhao's home and the Ping'an Inn in Datong District, and it was not until around the end of the evening that Liu Ma and Du Congjun were brought back one after another.

"Why is it so long?" , Cao Xiaohui asked the catch that brought people back.

"Sister Cao, this Mother Liu has something to do at home, she went home yesterday, her family lives in Shuifeng District, the road is not close, it took us a long time to find it."

"Sister Cao, this Du Congjun went out early in the morning to sell goods, he walked the streets and alleys with his burden, it is not easy to find him!"

"Got it, everyone worked hard!" , Cao Xiaohui nodded.

"Xiaohui, you send someone to Tan's house, find Ouyang Linlin, and ask her to recognize this Du Congjun in the dark, and see if it is the person who went to his house to talk to Tan Junhao for a long time."

"Understood", Cao Xiaohui nodded, turned around and beckoned to a catcher.

"Mother Liu", Nie Xiaohu said as he looked at an elderly woman in front of him.

"I've seen adults", Mother Liu looked at Nie Xiaohu with some fear.

"Don't be afraid, I'll ask you a few questions."

Mother Liu nodded timidly.

"What are you doing in the Tan family, and how long have you been doing it?"

"Back to my lord, I am a helper in the Tan family, and I cook on weekdays, wash clothes, and clean the house, and I have been at the Tan family for less than a month."

"Hmm", Nie Xiaohu nodded, and then asked, "Did you meet a man in black in the backyard the night before yesterday?" ”

"Yes."

"Then tell me about the situation!"

"The night before yesterday, around midnight, I finished cleaning the house and was about to take the sundries to the backyard to dump, but as soon as I went out the back door, I saw a man in black sneaking around in the backyard, and I was scared, so I screamed, and the man in black ran out of the yard and disappeared in a blink of an eye."

"Is the man in black a man or a woman?"

"It should be a man, how can a woman do such a thing?"

"You didn't see the man's face?"

"When the man had run away, I turned around, and found a dagger stuck in the post in front of the back door, and a letter was nailed to it, and I pulled the dagger down, and then Madame came down from the stairs, and I gave the letter and the dagger to Madame."

"Did you hear anything in the yard before you went out?"

"No", Liu's mother shook her head, "It was the dead of night, and there was no movement in the yard." ”

The corners of Nie Xiaohu's mouth raised slightly, and he said with a smile: "Okay, there's nothing to do with you, you go back first!" ”

"Yes, sir!" , Mother Liu bowed to Nie Xiaohu and turned to leave.

Nie Xiaohu looked at the back of Liu's mother leaving, his brows gradually furrowed, and then he pursed his lips and shook his head gently.

"Brother Tiger, Ouyang Linlin is here", Cao Xiaohui walked in quickly at this time, and whispered in Nie Xiaohu's ear.

"So fast?" , Nie Xiaohu's brows were furrowed.

"As soon as Xiao Zhang went out, I met her on the street, and she was about to come to me to ask how things were going, and it happened that she was in a hurry."

Nie Xiaohu nodded, and whispered: "Take Du Congjun to the interrogation room, you take her to take a sneak look at the crack in the door, and let her confirm it." ”

"Got it", Cao Xiaohui nodded and went out.

In the interrogation room, Du Congjun sat on a small wooden bench with a blank expression, and Nie Xiaohu sat behind the table opposite.

"What's your name?"

"The villain's name is Du Congjun", Du Congjun hurriedly replied.

"Where?"

"Shanxi people."

"How long have you been in Luoyang?"

"Is that him?" , Cao Xiaohui asked softly outside the door.

"Well, that's right, this is the person who came to my house that day!" , Ouyang Linlin took a closer look at the crack in the door and nodded heavily.

"I've been in Luoyang for nearly half a year," Du Congjun replied.

"Tan Junhao, do you know each other?" , Nie Xiaohu asked bluntly.

"Yes, of course I know!" , Du Congjun nodded, "We are fellow villagers and grew up together since childhood. ”

"Have you seen him lately?"

"Yes, twice, once six days ago, when I was selling goods on the street, I met him, and he invited me to his house to sit down."

"And what did you all talk about?"

"It's all about things when I was a child and some situations in my hometown, what else can I talk about?"

"Have you ever borrowed money from him?"

"Oh, this!" , Du Congjun scratched his hair, "Because I was doing business, I pressed a batch of goods and didn't sell them, and my hand was relatively tight, and I saw that Tan Junhao was relatively wealthy, so I borrowed two taels of silver from him, and he was also very generous, so he lent it to me at that time." ”

"What about your second meeting?"

"That was two days ago, I met him on the street, because I paid back the inn room money for the two taels of silver, so I thought about borrowing another five taels from him, but he excused himself that there was something at home and did not lend it to me."

"Hmm", Nie Xiaohu nodded, and then asked, "Do you know that Tan Junhao's father has a grudge against people?" ”
