Marry Changle in Datang

The books on the shelves were not in the slightest clutter.

Except for the dead lying on the ground, there was not a single trace of chaos.

This shows that the deceased did not fight before his death.

So, is it an acquaintance who committed the crime?

Qin Wenyuan came to the corpse.

I saw that the corpse at this time was facing the ground.

On the back of the deceased, knife marks could be clearly seen.

The thin clothes were pierced, and there were many knife marks.

Blood flowed from the wound, staining the clothes red.

"Death time."

Qin Wenyuan asked while looking at the corpse.

Han Min hurriedly said: "Wu Zuo said that the time of death was between Zishi and Choushi last night."

Between Zishi and Choushi?
From 11 to one in the middle of the night?
Qin Wenyuan nodded slightly, and said, "Have you asked anyone in the mansion what they were doing between Zishi and Choushi?"

Han Min nodded and said, "Everyone has been cross-examined."

"Except for the two guards who patrol at night, everyone else is sleeping."

Qin Wenyuan continued to ask: "How many of them can't be proved?"

Han Mindao: "Basically, there are other people who can testify."

"Ok?"

Qin Wenyuan looked at Han Min: "Is there anyone else who can prove it?"

"That Mrs. Han, his husband sleeps in the study, and she sleeps alone. How can anyone prove it?"

Han Min said: "It's like this. Mrs. Han has been having nightmares for the past few days. Some dare not sleep alone, so she asked her daughter to sleep with her, so her daughter slept with her. Both of them can testify."

"As for the other maids and servants, they all sleep in Tongpu, and they can all prove to each other."

"There are also two guards on patrol, and they can also prove each other."

"So, last night when Zi Shi arrived at Chou Shi, indeed everyone had an alibi."

Qin Wenyuan listened to Han Min's words and said with a smile, "This is really interesting."

"Some people don't have an alibi, which is very normal and easy to understand... No one can prove that it is normal to sleep in their own room at night."

"However, everyone here has an alibi, which is not normal."

Han Min blinked: "Isn't it normal?"

Qin Wenyuan said, "Don't you think it's too coincidental?"

"Everyone has an alibi. It's like knowing that something will happen at that time, so first find a proof of innocence for everyone."

Han Min thought for a while, then nodded immediately: "There is indeed something wrong. In previous cases, there would always be a few people who did not have an alibi."

"But this can't be taken as evidence, can it?"

Qin Wenyuan smiled and said: "Of course it can't be used as evidence. The alibi is to prove that they are not the murderer. Naturally, I can't just say who is the murderer just because of this."

"More evidence is needed to find the murderer."

…………

Qin Wenyuan examined the corpse carefully.

At this time, he found that the direction in which the deceased was crawling was towards the bookshelf.

Does this prove that the deceased wanted to go to the bookshelf and find a book, or something else on the shelf.

Then at this moment, he was suddenly slashed from behind?

Qin Wenyuan looked at the bookshelf.

I saw all kinds of books neatly placed on the bookshelves.

"The Analects of Confucius", "University", "Tao Te Ching", "Sun Tzu's Art of War"...

There is nothing particularly wrong with books, they are the most common, but also the most respected books.

The books are easy to buy and there is nothing special about them.

In addition to these books, there are some small objects on the bookshelf.

There is a small ornament carved from uncut jade.

Has an exquisite vase.

There was also a toad with some copper coins in its mouth.

Qin Wenyuan came to the bookshelf and carefully inspected these ornaments, but found nothing wrong with them.

They are all very common decorations, and may be expensive, but there are no secrets such as organs.

Qin Wenyuan narrowed his eyes.

He felt that this matter was getting more and more interesting.

There is no problem with the bookshelf, but the deceased is facing the bookshelf...

Is it because the murderer is very familiar with him, so while getting along with the murderer, he felt bored, or just happened to want to read some books, so he walked to the bookshelf?
And those who usually do this kind of thing can only show that the relationship between the deceased and the murderer is very familiar.

So much so that it doesn't have to be taken completely seriously.

After all, if you treat guests purely, it is impossible to just pick up a book and read it casually. After all, it means impolite.

But for people who are very familiar, even family members, there is no such concern at all.

Qin Wenyuan looked into the room again.

He focused on the windows and the door.

The windows were locked at this time.

Qin Wenyuan came to the window and pushed the window, but because it was locked tightly, the window did not move at all.

"Pure secret room!"

Qin Wenyuan looked at Han Min and asked, "Did the window be locked like this last night?"

Han Min nodded hurriedly: "Yes, the windows and doors are locked."

"There is no other place to go out of this room, so the officer has no idea how the murderer left after killing someone."

"Because of this case, there are so many strange things that I can't find any clues, so I have no choice but to ask Mr. Qin for help."

Qin Wenyuan nodded slightly.

"The doors and windows are locked, how did the murderer get out?"

"Could it be... there is a secret passage here?"

Qin Wenyuan looked around, but found no trace of any mechanism.

He walked out of the door again and stood outside looking at the room.

The front and back of the room are empty.

There are two other rooms next to each other on the left and right sides.

He walked directly to the rooms on the left and right sides.

After entering these two rooms, he glanced at the layout of the room.

He thought for a while and said to Han Min, "Go into the study and come to the wall."

Han Min didn't understand what Qin Wenyuan meant, but he obediently came to the wall.

Then, Qin Wenyuan knocked on the wall.

dong dong!

A dull voice sounded.

Qin Wenyuan said, "Did you hear the sound of knocking on the wall?"

Han Min hurriedly said, "I heard it, it's very clear."

"That means there is no compartment..."

Qin Wenyuan went to another room and knocked on the wall again.

Han Min's answer was still a very clear knocking sound.

Qin Wenyuan nodded slightly, and he returned to the study.

The front and back are open spaces, and the walls on the left and right are fine, which proves that there is no possibility of secret passages around the study.

What about the ground?

As Qin Wenyuan walked, he tapped the ground with his toes, and walked through the entire room without hearing the sound of his feet.

He checked the bookshelf again, as well as some moving objects such as vases that might be used as switches.

But as a result, nothing was found.

"The agency can rule it out."

"There are no secret passages, and the doors and windows are completely locked. How did the murderer leave?"

At this moment, even Qin Wenyuan felt the difficulty of this case.

Is it really an impossible perfect crime?

Qin Wenyuan narrowed his eyes.

He looked around the room again, looking for clues that he might have overlooked.

He believes that there is no perfect crime in this world.

As for the murder in a secret room, there must be a certain way to get the murderer out of the secret room.

So what is this method?

Qin Wenyuan fell into contemplation.

At this moment, in his brain, thousands of ways to kill in a secret room are appearing.

Murder in a secret room is a case often encountered by detectives in previous lives.

And it is also divided into categories, and it is listed as a large category separately.

It can be seen from this that there are many ways to kill people in the secret room.

Basically, the most important reason for any murder in a secret room is the method used by the murderer to cover up the possibility of committing the crime.

In other words.

Under normal circumstances, once you figure out how the Chamber of Secrets was created, basically, you are not far from solving the case.

However, Qin Wenyuan recalled what he encountered and all the methods related to the secret room murder case that he had read from the books.

But there is no method that can be consistent with the case in front of him.

Because the case in front of him is really a trick that is impossible to achieve.

Suddenly Qin Wenyuan thought of a case.

That was the first case he solved after he became the Shaoqing of Dali Temple.

In other words, it was precisely because he cracked that case that he became the Shaoqing of Dali Temple!
He went straight out and found the deceased's wife.

The deceased's wife was 35 years old, fair-skinned and very beautiful.

However, there was a smear of black under her eyes, and her complexion was a little haggard. It seemed that she didn't have a good rest at night.

From time to time, he covered his mouth and nose with a handkerchief, coughing constantly, and his body didn't look well.

These inferences were all automatically generated in Qin Wenyuan's brain the moment he saw Mrs. Han.

He looked at the haggard Mrs. Han and said, "Didn't Mrs. Han rest well last night?"

Mrs. Han sighed, "To tell the truth, Mr. Qin, I have recently contracted a cold, coughing continuously, and feeling unwell, so I have never slept well at night."

"Last night, I had a private conversation with my daughter in the middle of the night, so I went to bed later, so today's condition is even worse."

Qin Wenyuan nodded slightly, and he looked at the woman beside Madam Han who was supporting her.

That is Mrs. Han's daughter.

The name is Han Xin.

At the age of 16, Han Xin is fair and beautiful, and he has inherited all the advantages of her mother at first glance.

At this time, Han Xin looked at Qin Wenyuan timidly, as if he was a little afraid of Qin Wenyuan.

Qin Wenyuan smiled and said to Han Xin: "Miss Han, I don't look so scary, right?"

Han Xin hid behind Mrs. Han and said, "Mother said that I'm leaving the cabinet, and I can't casually contact other men."

Upon hearing this, Mrs. Han hurriedly said, "Master Qin is different from other men, so you don't have to be afraid."

She looked at Qin Wenyuan again, and said, "Master Qin, I'm really sorry, the little girl is very timid, and after going through this incident again, she has become even more courageous. I hope Master Qin will forgive me."

Qin Wenyuan took a deep look at Han Xin, then shook his head with a smile, and said, "I understand, Madam Han, don't worry, I won't care about it."

Mrs. Han expressed her gratitude to Qin Wenyuan.

Qin Wenyuan withdrew his gaze and looked at Mrs. Han again. He asked, "Mrs. Han, when you called the door this morning, did you notice that anyone was missing?"

Mrs. Han blinked her eyes and said, "I don't understand what Master Qin means."

Qin Wenyuan explained: "When you knocked on the door, the person who should appear did not appear, and then when you entered the room, you found that the person who did not appear originally appeared again."

What Qin Wenyuan said was the method used by the murderer when he uncovered the murder in the first secret room.

The murderer was hiding at the door.

Then, as everyone knocked on the door and entered, while everyone was shocked by the dead, he naturally appeared behind them, never arousing anyone's suspicion.

And through this method, a perfect secret room murder was completed.

So is this case the same?

Qin Wenyuan did not appear at the first scene, so he could only learn about it from Mrs. Han.

Mrs. Han thought about it seriously, then she shook her head and said, "I didn't notice this."

"But the ones who came to knock on the door at that time were the housekeeper, a few servants and the nurses, and the two maids who accompanied me. Except for us, no one else knew about it."

"Then I knocked open the door, and I panicked because the master had an accident, so I didn't pay special attention to whether there were too many people..."

"But I glanced at the others in a daze, and I didn't seem to find any extra people."

Qin Wenyuan nodded slightly, not surprised.

After all, in that case, apart from glancing at other people occasionally, he really wouldn't pay special attention to whether there were too many people.

However, this does not prove that Qin Wenyuan cannot investigate the case in this way.

After all, there were quite a few people at that time.

Mrs. Han can't tell everyone.

But other people will always remember a few people in their memory.

At that time, after comparing each other's answers, they will naturally be able to judge whether there is an extra person who should not appear.

After two sticks of incense.

While wiping his sweat, Han Min came to Qin Wenyuan's side.

He said to Qin Wenyuan: "Lord Qin, the lower officials have already questioned everyone, and based on what they said, compared and compared with each other."

"And the result is that there are no redundant people appearing!"

"The original number of people knocked on the door, but after the door was opened and the body was found, there were still as many people."

"The numbers haven't increased."

Listening to Han Min's words, Qin Wenyuan's eyes became deeper and deeper.

In this way, the method used in this secret room is different from the Turkic case that I solved at the beginning.

That would be interesting.

The doors and windows were closed tightly, and no trace of any mechanism was found.

The entire study room is completely secret.

There are no secret passages, no hidden doors.

The murderer did not use special hiding methods to hide among the crowd.

How did the murderer leave the secret room after the murder?
Qin Wenyuan frowned slightly.

Seeing Qin Wenyuan lost in thought, Han Min quickly held his breath, not daring to disturb him.

At this moment, Han Min also realized the difficulty of this case.

After all, in his mind, Qin Wenyuan would immediately solve any case that happened to him.

But in this case, Mr. Qin also seemed to feel difficulties.

This is enough to show how troublesome this case is.

It seems that it is extremely correct for me to choose to ask Mr. Qin for help without hesitation.
