Luo Xiaolin's words were impeccable. After consulting with the acting prosecutor, Hua Muli decided to detain the Xie brothers, and then the group went to Luo Xiaolin's home.

The surrounding fence is surrounded by a green lawn, and a two-story building stands tall, This is Luo Xiaolin's home.

Hua Muli summoned five people who could testify for Luo Xiaolin at home. Of the five, three were residents and the other two were merchants.

"Luo Xiaolin, you said you were reading by the window on the day of the crime?"

"yes, it's the window downstairs."

"Okay, can you recreate that scene?" Luo Xiaolin took a pipe in his mouth, sat by the window, and began to read.

Hua Mu immediately asked the five people about this scene.

"On that day, did Mr. Luo Xiaolin sit and read as he does now?"

Five replied in the affirmative, one said he had seen it at noon, some said he had seen it at about two o'clock, and one said he was passing by when the church bell rang and happened to remember. ”

From the testimony of these five people, it can be seen that Luo Xiaolin was not at the scene from noon to four o'clock on the day of the crime.

"So, did the three Xie tell a lie?" Li Yunshan asked in a low voice.

"Oh, really?" Lang Xiaobai said noncommittally.

"This case seems tricky!" Lang Xiaobai said.

However, Hua Muli's reaction was very cold, and he just glanced at Lang Xiaobai silently.

"Mr. Hanakiri, you seem to be in trouble."

Hua Muli didn't react except frowning. Lang Xiaobai was not discouraged, and said to himself: "As far as I think, this case is not difficult to detect."

Hua Muli was excited, and Lang Xiaobai's words obviously stimulated him: "I have already thought about this case very clearly. ”

Hua Muli's face became ugly, and the acting prosecutor also showed dissatisfaction. They thought to themselves that the guy who didn't know the sky was thick and the earth was just a little detective, but he was talking nonsense here. Hua Muli still suppressed his anger and sneered: "If you are really as powerful and extraordinary as Li Yunshan said, we racked our brains and worked hard to solve the case, but you can see it at a glance, it is really unimaginable, of course we have to listen to your high opinions!"

Lang Xiaobai disagreed with these sour words, and replied with a smile: "The time is not yet ripe, you will know when the time comes." You can now call new witnesses. ”

"New witnesses? Who is he? Where is he?"

"I don't know!"

"What exactly do you want to do?"

Hua Muli became more and more angry. Li Yunshan didn't know why, he hurriedly said, "Brother Lang, your mistake has been made again!" No apologies yet!"

"Don't panic, things will be known soon!" Lang Xiaobai paced to Hua Muli's side, lowered his voice and said, "The address of the new witness is in Luo Xiaolin's wallet. There's a business card with four small holes hidden in your wallet, and you just have to find it. ”

After hearing this, Hua Muli was very surprised. He ordered Luo Xiaolin to be brought and got the wallet.

It's a very new wallet, but I don't see a business card.

Lang Xiaobai volunteered and took the wallet from Hua Muli and found it. "Oh, the business card is here!"

As he spoke, he pulled a business card out of his wallet.

A crumpled business card with four small holes. "Miss Robodelle" is printed on the top and there is an address below.

Luo Xiaolin was shocked and hurriedly explained: "I didn't know that this business card was here at all!" Peng Qiuwen turned his home upside down for it, and he didn't let go of every book, but he still worked in vain, what a poor man! ”

Luo Xiaolin said as he spoke, as if he was about to shed tears.

"Why is he looking for this business card?"

"I don't know. Maybe he's looking for Miss LoBodale's address. ”

"What do these four holes represent?"

Hua Muli and the acting prosecutor who came with him asked suspiciously, they were eager to find something valuable from their answers, but Luo Xiaolin's answer was a big disappointment.

"You don't know, Peng Qiuwen and I often play poker for fun, and often play all night long. Punching holes in business cards is to win and lose respectively, and whoever wins will make a hole in the business card, which is what Peng Qiuwen came up with. ”

"But how did it end up in your wallet?"

"This one confuses me a little."

After a long time, Luo Xiaolin seemed to remember something.

"I remember, one night we had a good time and we started drinking. While chatting, I took out the wallet I had just bought and showed it off to him.

Peng Qiuwen picked up the wallet and played with it, he inserted the business card next to him for a while, and pulled it out again.

"Later, we talked all over the world, and then later, I went home in a shaky way. When people are old, they are very forgetful, not to mention the fact that they drank so much wine that night. ”

Luo Xiaolin said seamlessly, and others had nothing to say.

"Why did Peng Qiuwen look for that business card?" Hua Muli asked.

"I don't understand it either."

"It's a real mystery to solve."

Hua Muli nodded secretly, and then said thoughtfully: "Why Peng Qiuwen is looking for a business card is a mystery, and Lang Xiaobai's knowledge of the business card is also a mystery, a more difficult mystery to solve, Lang Xiaobai just saw Luo Xiaolin for the first time, and he knew that the business card was hidden in the wallet." Who is Miss Lobredale? What does she have to do with this case?...... We had to summon her. ”

Hanagi sent the summons to Miss Robodelle. It so happened that the young lady went to country E, and a week later she returned to Dongzhou and went to the Security Bureau when she saw the summons.

As soon as they met, Hua Muli took Luo Bodai to Peng Qiuwen's residence, and Li Yunshan and Lang Xiaobai also arrived.

Miss Luo Bodai was shocked to hear the news of Peng Qiuwen's death. Under Hua Muli's questioning, she told her relationship with Peng Qiuwen.

"I've only met Mr. Peng Qiuwen once, and here he is."

"Why are you here?"

"I buy something from him. His asking price was too high, and I had to go to country E to raise money with my relatives. ”

"What's that?"

"An old piece of paper."

"Is it valuable?"

"It has to do with our background: our great-grandmother, who was also a famous courtesan in Dongzhou, has a romantic nickname 'pretty woman'. At that time, the Northern Emperor fell in love with her and wrote eighteen love letters. My great-grandmother hid these love letters in the back cover of The Complete History of the Ming Dynasty, bound in calfskin.

"After my great-grandmother's death, we found that the fourteenth was missing as we sorted through her belongings, as did the fourteenth love letter hidden there.

"The fourteenth love letter is the most crucial of all eighteen and is of great importance to us. That love letter is about whether it can be confirmed whether the great-grandmother and the child of the Northern Emperor, that is, our grandfather, are the eldest son of the Northern Emperor.

"Our great-grandmother died of illness before she could ascend to the throne. Her son did not receive an official title and remained in exile. Our brother and sister Luo Bodai are the descendants of the Northern Emperor, and only that love letter can prove our background, in that case, our brothers and sisters will definitely be honored in the aristocratic class, and we will be able to glorify our ancestors.
