The waiter brought two cups of hot coffee and politely placed them on the table. He said, "Please use it slowly." Then leave.

Nie Ming looked at Song Jingci and shook his head in confusion: "I don't understand, what is the purpose of you bringing me here?" ”

"One of the aspects of psychology that I study is about criminal psychology." Song Jingci said, "This matter - please forgive me, before today's meeting, I regarded you as the first suspect like the police, according to my analysis, if you are really the murderer, you will definitely try to avoid coming to this place, so as not to arouse suspicion." And you don't come here for a steak – but now, you're really here unsuspecting. So I thought, maybe I really misunderstood you. ”

Nie Ming frowned and thought for a while, and said, "I think, such a big thing happened here, many people should know that in this case, normal people should avoid coming to this place." ”

"It seems that you really don't know. My father didn't fall in front of this restaurant or on the street. It's the back door of the kitchen in this dining room — it's a nobody-by-passer, a place for clutter to be stacked. My father fell there, and not many people saw it, only two cooks found it and rushed to the police. And the police quickly blocked the news, so not many people knew about it at all. ”

Nie Ming stared at Song Jingci: "So, if I happen to not want to eat steak today, then you will treat me as a murderer?" ”

"Of course not." Song Jingci said, "I still have a lot of ways to test you, but now, I don't think I need it." ”

Nie Ming's eyes looked out the window and sighed softly.

"What's wrong, Mr. Nie. You seem to be unhappy? ”

Nie Ming turned his head: "Miss Song, what do you think I should do now?" Are you relieved that you didn't think I was a murderer? Have you ever thought that I was also a victim in this incident! ”

Song Jingci opened her mouth and did not speak.

"Now, your test is over, thank you for not treating me as a father-killer. Can I go home? Nie Ming stood up.

"Wait, Nie Ming, I'm ......"

"Maybe you have another test? Miss Song Jingci. ”

"No, I...... I hope you can help me. ”

"Help? Don't you think this request is more appropriate to make to the police? ”

"You're the only one who can help me, Nie Ming." Song Jingci looked serious, "Please sit down and listen to me, okay?" ”

Nie Ming looked at Song Jingci's eyes, and he saw expectation and pleading in those clear eyes. He could only sit down again.

"I only have my father, Mr. Nie. My mother died in childbirth while giving birth to me. For as long as I can remember, my father has only cared for and loved me, and he is the closest person to me. But now, he died a tragic death like this...... Song Jingci's eyes dimmed, and her voice was a little choked, "I think, you can understand my feelings, right?" ”

"I totally understand and I am very sorry. But I really don't understand, how can I help you? ”

"Nie Ming, I now fully believe that you will not be the murderer of my father, so I think you may be able to provide me with some useful information so that I can use this as a clue to investigate the murderer of my father."

Nie Ming thought for a while and said, "Sounds like you're pretty sure that your father died of murder and not suicide?" As far as I know, even the police have not been able to make a decision on this case. ”

"That's the problem. Based on my judgment and the conversations the police had with me, I had the feeling that they would make this a suicide case. However, this is absolutely impossible! Song Jingci's tone became excited, "My father will never commit suicide!" On the afternoon of the day he died, he was still talking to me on the phone, and there was no sign of suicide! Our conversation was as natural and easy as usual! ”

"So, you think it's up to you to investigate this case and uncover the truth?"

"It's the last thing I can do for my father."

Looking at Song Jingci's determined eyes, Nie Ming felt a sense of admiration from the bottom of his heart.

"Okay, Miss Song, I promise you. I will give you my full support and assistance in your investigation of this case. It's also about my innocence, and I have to clear up this misunderstanding with everyone. Nie Ming said.

"Thank you, Nie Ming. Thank you so much. ”

"Okay, now the question is, how do we go about investigating?"

"I think we should take the only clue we have now."

"What do you think is the only clue?"

"You're always used to being told by others, right?" Song Jingci smiled, "Actually, you know better than me, right?" ”

Nie Ming had to admit that Song Jingci's psychological analysis ability had reached its peak. He had to be more honest with her: "You mean that black book, that black book that was lost at your father's house, right?" ”

"What could be more important than something like this? My father got this black book from Yu's house and was killed within four hours; I didn't lose anything at home, but this book was missing; The passage that my father wrote on the notepad was all about this black book. Nie Ming, what do you think these offer us? ”

He thought for a moment and said, "At least let us know the direction of action." ”

"Exactly."

"If we can find this black book, then all the mysteries will be solved." Song Jingci stared at Nie Ming's eyes and said, "I feel from the conversation with you just now - you don't think it's very difficult to find that black book, right?"

Nie Ming shook his head: "I don't think that black book will be easy to find, I just think we have some clues—that is, the text that your father left on the notepad." If we can figure out what those paragraphs mean, we may be able to uncover the secret of the black book. ”

"That notepad, as a relic of my father, is now with me, in my house. But I couldn't understand what that meant. What about you? ”

"I don't understand it either."

Song Jingci thought for a while and said, "On the afternoon of my father's death, he was at home with you. He finished reading this black book, and then asked you to talk in the courtyard once, right? What did he tell you? ”

"He seemed nervous, flustered, even scared – I don't know why he was like that. He said that what was written in this little book was not an ordinary financial problem at all...... He also said that he wanted to confirm the contents of the notebook, and after that, he left Yu's house without saying goodbye. ”

"So, he didn't say a word about the contents of the book?"

"Not a word."

Song Jingci thought for a while: "That's all my father said? ”

Nie Ming rubbed the coffee cup back and forth with his hand, and after a while, he whispered, "There is one more thing, but ...... Even the police don't know about it. ”

"What is it?"

Nie Ming frowned and thought for a while, and said, "I can tell you, but ......"

He paused, looking speechless.

"Nie Ming, tell me, you don't need to hide anything from me."

"Oh well. In fact, although the old lawyer did not tell me about the contents of the book that afternoon, he told me another secret of the book. ”

Song Jingci didn't speak, waiting for Nie Ming to continue.

"This black book is just a disguise, and in the middle of it, there are 30 pages of paper. And these 30 pages are the key! ”

Song Jingci slowly leaned back on the back of the sofa and fell into deep thought.

After a few minutes, Nie Ming asked, "What did you think of?" ”

Song Jingci looked at Nie Ming and said, "I think, you're in trouble now." You are in danger. ”

Nie Ming was taken aback and asked, "Why?" ”

"Do you remember what my father wrote in his notepad? He seemed to have a premonition that he would be killed. At the same time, he said, 'If I die, let this secret live forever'. Have you thought of it? Nie Ming, what does this mean? ”

It means that he may have hidden those 30 pages somewhere - I had thought about this before. But what are the dangers you're talking about? ”

"Let's look at it this way: the murderer's purpose was to get this little book. However, what will he do when he gets it and finds that it doesn't have what he wants? ”

Nie Ming began to get nervous: "Perhaps, he will go to the old lawyer's house again to look for ......" He paused for a moment, "But, why do you say that I am in danger?" ”

"It was indeed one of the possibilities that he would go to my father's house to find him. But another possibility is that he will think that you are the only one who knows the truth now and come straight to you! ”

"However, the old lawyer didn't tell me the contents of the book!"

Song Jingci shook his head and said, "You said it yourself, why does he think you are telling the truth?" ”

Nie Ming felt cold sweat begin to seep down his spine, and he had to admit that he had ignored the problem. This situation analyzed by Song Jingci is entirely possible!

"And I'm in danger right now." Song Jingci continued, "He may also think that my father did not put those 30 pages with me. ”

"If so, it really sucks."

"Wait, if he really thinks so......" Song Jingci suddenly looked panicked, she stood up suddenly, "If he really did this......"

"Why, what do you think ......?"

"I have to go home right away! My brother is at home! ”
