On the day of the incident, Zhao Lichen happened to be at An Xin's house, because the piano in her home needed to be adjusted frequently.

Almost every month, I have to run over to adjust, but I didn't expect that this time after adjusting the piano, the weather suddenly became a little gloomy, seeing that a heavy rainstorm was about to fall, An Xin didn't want to call Zhao Lichen back at this time, for fear that his eyes would be inconvenient, and something would happen on the way back.

The kind-hearted An Xin cleaned up at home, found a room and asked Zhao Lichen to stay here for one night temporarily, to see that after the heavy rain stopped tomorrow, he asked someone to send him back.

The two of them have been relatively familiar with each other over the years, and they often come and go, although Zhao Li doesn't know what An Xin looks like, but he still knows a little about this woman.

Unlike others, he relies on his voice to analyze a person, and from listening to her play the piano every day during this time, he knows that this woman is not an ordinary person, she should be the kind of lady who is highly educated.

He doesn't care about his reputation, anyway, he is a blind person, a blind man who can't see anything, and naturally he doesn't care what others think of him.

But because he lives here, it affects An Xin's reputation, which is a bit too much, so he doesn't want to stay here.

It was still An Xin's repeated insistence, and the location itself was relatively remote, so he agreed.

But Zhao Lichen also knew what he should do, and he locked himself in the small room downstairs all night, and he didn't even go out of the door, let alone go out to drink water, and he couldn't even hold back his urine this night.

And that night, he couldn't fall asleep at all, after all, it wasn't in his own home, and there was a lot to avoid, lying in bed all night.

In the middle of this, he did hear the sound of someone coming in outside, but he didn't think much of it, and he didn't even leave his bed to listen to the wind and rain outside.

After the rain stopped, he left the room as soon as possible, and at the same time left An Xin's home.

From beginning to end, he was because he didn't want to make trouble for An Xin, and the fact that people were terrible, he knew it to no one else, so naturally he would not bring such trouble to An Xin.

But he never imagined that nothing would happen because of his self-discipline.

After that time, he didn't have any contact with An Xin.

He didn't know if it was because he stayed at An Xin's house that night, and in the end he would cause her trouble.

It's just that he never expected that half a month later, when he called again to ask if he needed to adjust the piano, he suddenly received an unexpected message.

An Xin committed suicide at home after that storm.

After hearing the news, Zhao Lichen's first thought was that this was simply impossible.

Although he couldn't see anything, for this woman who was both familiar and strange, he was very sure that An Xin would not commit suicide, and she would never commit suicide.

"The song I gave you yesterday was the last time I saw her, and she played it with her own hands!" Zhao Lichen recalled the last time he saw An Xin, and put away the smile on the corner of his mouth for the first time: "That time was the last time I heard her piano, and I haven't heard it since." ”

"How many times did you hear the door open, how many times did you hear the engine of a vehicle that night?"

This is what Ding Fan wants to know most now, and it is also a key point in this case now.

There are only three people at An Xin's death scene who are still alive, and the words of two of them cannot be completely evidence, and they can't provide superfluous clues now, and the only person who can be a little rational at the moment is only Zhao Lichen.

Although he is blind in both eyes, such a person will be more sensitive in hearing, not seeing does not mean that he cannot hear, sometimes, what he hears, often can explain a lot of things.

"That night, I did hear the engine of the car...... Twice!"

Zhao Lichen did think about it for a while this time, although twenty years have passed, for him, although the past time is very long, but every day he will recall this matter, especially every detail of the beginning.

So he remembered this incident very clearly in his heart, and it was not difficult to recall, but he didn't want to make any mistakes when talking about it.

But the sound of the engine twice is obviously not quite right.

According to Ding Fan's previous analysis, it is very likely that there is more than one person at the scene.

But just the sound of two engines, it seems a little wrong.

At least after Wu Lili's confirmation, Ding Fan already knew that they drove back before An Xin died.

That is, the sound of the engine that appeared at the scene at that time, it is very likely that they left it behind.

The sound of the two engines should have been left by them back and forth, so apart from them, will anyone appear in advance, could it be said that this person did not drive that time.

"Where is the room?" Ding Fan frowned and thought for a moment, then asked, "Did you hear any extra sounds before the engine sound?"

This time, Zhao Lichen didn't speak, but closed his eyes, which he couldn't see, as if he was trying to remember something.

Because the question raised by Ding Fan is a detail that he has never noticed.

And after Ding Fan asked, he didn't say much, but kept looking at him, not bothering him for the time being, waiting for him to slowly recall.

But after waiting for a long time, Zhao Lichen said very firmly: "No, I didn't sleep all night that night, from beginning to end, I only heard the sound of a person entering the door, judging from the footsteps, I won't hear wrong, there is only one person." ”

At this point, Ding Fan doesn't need to suspect anything, a person who can't see, his ears are abnormally sensitive, which is his special feature.

Ding Fan came to him, the fundamental reason was here, he wanted to use his ears to investigate that night, in addition to Li Heng, was there a third person present?

But looking at it now, it seems that I really thought too much, and on the day of the crime, there were really no superfluous people at the scene.

In this way, the previous conjecture is indeed a bit unrealistic.

"Actually, I know what you're thinking!" Zhao Lichen took a deep breath, shook his head slowly and said: "I know you have some other conjectures, but it's really not, that night, I heard the sound of the door outside very clearly, and there was definitely only one person in and out." ”

In this way, there is only one person left as the biggest suspect now.

"I just want to make sure that only one person has ever been in and out of that house on the night of the crime!"

Zhao Lichen's purpose in saying this, in fact, Ding Fan knew it as soon as he heard it.

If it weren't for the fact that Zhao Lichen himself had no connection with the An family and the Li family, Ding Fan would even be a little suspicious of his purpose in saying this.

Now it seems that things have gradually become simpler from the original complication.

In fact, the matter itself is not very complicated, the key point is that this case has passed for too long, and there is no direct witness evidence.

I have to admit that sometimes, time is really the biggest enemy of the police.

It is often said that time erases everything.

Now it seems that this damn time has easily erased the truth.

"Everything that happened at the time of the case, in fact, it is not difficult to speculate, what really embarrassed me is that there are no witnesses and evidence!" Ding Fan shook his head a little helplessly: "There is no need to go to the scene of the crime, I still trust the police here, they should have searched the scene, and there will be no clues left at all, if there were, it would have been sent to the police station a long time ago." ”

Ding Fan had thought about this before, and asked Mi Mi to look for it before, but he didn't find anything valuable except for some things that are usually used at home.

Except for the relics of the deceased, which have been returned to the families of the deceased, nothing remains.

"Actually, it's not necessarily nothing, you're too anxious now, maybe you should go to the scene to take a look!" Zhao Lichen stood up, tidied up his clothes and said: "Actually, I think you should go, I don't know if the original piano is still there, maybe you can go and listen to it, maybe it can help you with anything." ”

Not to mention, this is not a good idea, maybe he can try it, maybe there will be some unexpected gains!

Time can indeed hide some truths, but sometimes, time is also a bit like a blind person, and when you are not careful, there will be some omissions.

"You forgot to take your things!" Don't care how good Zhao Lichen's perception is, but sometimes, his eyes can't see, after all, he is still a little restricted, at least when he forgets something, he doesn't know if he doesn't wear sunglasses: "It seems that I still have to go out today, and the poison of this big sun really can't be hidden!"

Zhao Lichen stretched out his hand on the table, stretched out his hand and slid it twice, picked up the eyes on the table and said with a smile: "It seems that you already understand what I mean, believe me, listening to that tune must be good for you, if that piano is still there!"

After saying the last sentence, Zhao Lichen stopped talking nonsense, directly pushed open the door of the ward, and walked out from the sofa position very accurately.

Now Ding Fan finally stopped doubting his words, as a blind man, it was really surprising that he did this.

In fact, it is not surprising to think about it, these blind people, who can't see things with their own eyes, will make some records after entering the door, how many steps they have taken in the door, what kind of direction, they can accurately record.

This is an instinct and a habit of life, after all, they can only do this after not having the convenience of their eyes.

It is precisely because of their carefulness and meticulousness that Ding Fan still takes what Zhao Lichen said very seriously.

"The work of the police is originally a hard job!" Ding Fan glanced at the big sun outside, squinted his eyes and sighed and said: "I thought I could be lazy in the room, but now it seems that everyone is eager to drive me away behind with a whip in their hands!"
