The secret war is silent

In addition to looking for clues to solve a case, there is another point, which is to make bold guesses and carefully verify. This is actually the same as scientific research.

Take fingerprints.

This has been used in solving crimes, but it certainly cannot be used in ordinary cases. After all, the technical means are relatively primitive.

There is no fast comparison technology like that of later generations, and even if different fingerprints are found, it can only confirm the existence of the suspect, but not the identity of the murderer.

However, Luo Yao was basically certain that not many traces would be left at the scene.

The trace inspection is just a formality, and if the thief leaves fingerprints, it can be compared at the end.

He was certain that the thief must have worn gloves when committing the crime. Of course, he could not rule out that he was careless...

Whenever possible, don't let it go.

The transcripts of the interviews were continuously collected into Luo Yao's hands, and the situation that night gradually became clear in Luo Yao's mind.

According to the description.

Luo Yao judged that the time period when the top-secret documents were stolen should be between 2 a.m. and 4 a.m., which happened to be the time when the confidential personnel in the secret room were not around.

The old man rested around this time every night, and he happened to be away from Huangshan Mansion last night, so there was no need for the confidential personnel to stay in the secret room.

According to the duty regulations, he needs to stay in the secret room.

But he went back to his dormitory to sleep.

Of course, even if he stays in the secret room, he may not be able to prevent top-secret documents from being stolen. This is the time when people are most sleepy.

The key to the secret room door is controlled by the guard room, so if this confidential officer is unlucky, he may be punished severely.

Does anyone know that you secretly go to the dormitory to sleep when you are on duty? Luo Yao called the confidential officer to him and asked.

The confidential officer hesitated and reported the names of the two people.

These two people are the guards on duty in Yunxiu Tower who are responsible for the security of the secret room. They naturally knew when they saw the confidential personnel leaving and not coming back.

There is enough space in the secret room, and it is cooler inside than outside. Why don't you sleep in the secret room? Luo Yao concluded that the confidential personnel must have something to hide.

Normal people wouldn't do this.

Beads of sweat began to drop from the confidential officer's forehead instantly. Obviously, he had lied. He left his post without authorization and it was not as simple as returning to the dormitory to sleep.

Say, you know the consequences of concealing it. I can use wartime military laws to pull you out and shoot you? Luo Yao asked sternly.

Sir, I was wrong. I went on a tryst with someone else... The confidential officer was immediately frightened and told the secret.

Tryst, with whom?

There is a maid next to Madam...

When did you go there, when did you see her, how long have you two been together, tell me the truth! Luo Yao shouted coldly.

I have known each other for more than half a year, but we have only been together for the past two months... The confidential officer knew that if he wanted to save his life, he could only tell the truth, otherwise his life might be in danger if he lost his official position.

Where's that maid? Send someone to control her immediately. Luo Yao's face darkened. This kind of thing seems not uncommon.

Young men are full of blood, fair ladies, and gentlemen. One is a confidential member of the attendant room, and the other is a maid next to the madam. Logically speaking, there are rules and regulations, and they have no chance. But as long as the rules are set by people , there will be loopholes.

What's more, opposites attract each other, which is driven by human instinct.

It is impossible to completely ban it, you can only restrict it, whether it is rules or self-restraint, but it is inevitable that there will be no accidents.

After a while, a twenty-year-old girl was brought over. Her face was pale and her hands were shaking. It was obvious that she was frightened by this incident.

She has never seen this kind of formation since the day she was born.

Miss Xiaolian, don't be afraid. We just want to verify something with you. As long as you answer truthfully, we won't embarrass you. If you don't tell the truth, then the problem will be serious! Do you understand?

The girl named Xiaolian nodded quickly.

Okay, do you know Zhou Yan, the confidential officer in the Confidential Room of the Attendant's Room?

Xiaolian nodded.

Answer me 'yes' or 'no'

Yes. Xiaolian agreed fearfully.

Soon, Luo Yao roughly understood the relevant situation. Zhou Yan and Xiaolian did secretly get together. After the two secretly tasted the forbidden fruit, they ate the marrow and learned the taste. As long as the old man did not live in Yunxiu Tower at night, he would I secretly look for opportunities to have private meetings with Xiao Lian, mainly at night. During the day, Xiao Lian has a lot of work to do and has to serve his wife.

Not many people knew about Xiaolian's relationship with Zhou Yan. Another maid who lived with her in the same dormitory knew about it, but no one else knew about it.

Moreover, both Xiaolian and Zhou Yan took confidentiality measures and did not reveal the other's identity to anyone who knew about the matter.

In other words, although the guard who knew that Zhou Yan was having a private meeting knew what he was going for, he did not know who the person he was meeting with was also unknown to the person in Xiaolian's dormitory.

This protects the other party to the greatest extent.

If it hadn't been for the theft of top-secret documents from the secret room of Yunxiu Tower, their relationship might not have been exposed now.

Zhou Yan, a confidential officer, should have thought of this, but this maid named Xiaolian didn't have such a mind.

Zhou Yan, have you disclosed the nature of your work and the secrets of the confidential room to Xiaolian? Luo Yao asked.

No, I just told Xiaolian that I work in the confidential room. She doesn't know what I do specifically. Zhou Yan said with certainty.

Deputy Director Luo, preliminary investigation of these two people's background revealed that there is no problem. Hu Yingjie came in from outside, leaned down and whispered in Luo Yao's ear.

I understand. The maid Xiaolian shares a bedroom with will also be investigated. Also, anyone with whom these two women usually have a good relationship will also be investigated, Luo Yao said.

yes.

Hu Yingjie bowed his head and left. Time was tight and the task was heavy. He had to seize every minute and every second. He only had three days to solve the case.

Time passed by minute by minute.

The Attendant's Office arranged an office space for Luo Yao in a square with guards not far from Yunxiu Tower.

There is also a bed for temporary rest.

If the case is not solved, Luo Yao may not be able to go back for the time being.

Luo Yao already has a suspect as to the identity of the thief who stole top-secret documents from the Huangshan Mansion, but the investigation still requires evidence.

You cannot decide a case based on mere guesswork, as that is prone to error.

Therefore, we have to go step by step and sort out a reasonable thread from the myriad of clues to catch this thief.

Luo Yao nervously solved the case.

Xia Fei is here.

Luo Yao led him to the secret room, pointed at the safe and asked, Xiao Fei, can you open this safe without any key or password?

As soon as he said this, Lieutenant Zhang Xiaozheng, who came in with Luo Yao, was startled. This is a safe imported from Germany. Although it is not the most advanced, unless violent force is used to break it, I have never heard of anyone being able to open it without a key. Open with password.

Such a high-end safe, brother, you think so highly of me... Xia Fei took a closer look, and his face suddenly fell.

Luo Yao asked calmly: If you can't do it, is there anyone who can?

Xia Fei thought for a moment: My ability is only one-tenth of my master's. If he were alive, he might be able to do it.

are you sure?

Yes, this kind of lock is not beyond the scope of what I know now. If my master is alive, he should be able to open it.

How long will it take?

It's hard to say, it could be dozens of minutes or several hours. Xia Fei said.

Can anyone open this safe within an hour? Luo Yao asked.

Yes, my master said that unlocking is not his top ability. There are many people in the world who are much better than him. He only knows four or five...

Take a look. Are there any signs that the keyhole has been opened by other means? Luo Yao ordered.

yes.

Xia Fei walked over, took out a magnifying glass and looked at it carefully.

Brother Yao, there is a mark here. It is not caused by the friction of the key. It should be a special lock-picking tool. I don't know what it is specifically. Every lock-picking master will have his own set of lock-picking tools. Some of these tools are even Some of them are passed down from generation to generation, and some are made by oneself. They are the secrets of unlocking people. My master didn’t want me to follow his old path, so he didn’t teach me his set of tools. Xia Fei regretted. said.

Luo Yao nodded, Xia Fei's judgment was not wrong.

This keyhole is normal and should be opened with a key.

It happened to correspond to the key kept by the confidential personnel in the secret room. The key had not been stolen before, which at least made Zhang Xiaozheng breathe a sigh of relief.

But how did the thief avoid the guards on the road from the entrance of Yunxiu Tower to the secret room? You know, although there are no sentries at the door of the secret room, there are at least three levels of sentries coming in from the outside.

How did this person sneak in while avoiding so many pairs of eyes? There is no direct passage from the outside world.

Could it be that he saw a ghost?

Is there a vent in here?

Yes, there are also secret rooms, but the vents are very small and no one can get in. Zhang Xiaozheng said.

Luo Yao checked the vent. Zhang Xiaozheng was right. The vent was very small and had a fence welded with steel bars. The exit was also extremely small, and even a slightly larger cat might not be able to pass through.

Even if this thief had the bone-shrinking skill, he wouldn't be able to get in. No matter how powerful he is, he can't shrink his head.

Moreover, there are no signs of damage to the welded steel bars of the vents, so people should not have come through this passage.

Then there is only one possibility.

He had been hiding in Yunxiu Tower and waited until the time came before taking action. After he succeeded, he left as soon as possible.

Guards usually have two posts. If one person has a problem, the other person will definitely find out. You need to go through three checkpoints to come in from the outside. Under normal circumstances, the guards at the three checkpoints do not move around each other unless it is the last checkpoint near the secret room. There is a problem with the guard. Otherwise, the probability of problems occurring in all three levels is extremely low.

Adjutant Zhang, was this place cleaned on a routine basis yesterday?

Yes, Deputy Director Luo, how do you know? Zhang Xiaozheng asked in surprise. He remembered that he did not mention this to Luo Yao. He only said that cleaning should be done once every three days and twice a week. It is a confidential place. There is no need to clean it every day. All must be cleaned.

Once the cleaner comes in, the procedure is very cumbersome.

No, the time was wrong. The thieves did not choose to do it at night, but during the day. It should be after lunch. It is summer, and this time is also when people are the sleepiest.

Call Zhou Yan over!

yes!

Zhou Yan, did you take a lunch break yesterday?

Yes, I came back from lunch and felt a little sleepy. I fell asleep on the table! Zhou Yan said.

How long have you been asleep?

More than an hour, I can't remember the specific time...

You didn't notice anything unusual when you woke up?

No. Zhou Yan recalled it and shook his head.

Then since you woke up, when has the safe been opened?

No, I didn't open it until this morning. Zhou Yan said.

Yes, top-secret documents are stored in it and rarely taken out again unless it is useful. From Zhou Yan's nap to the next morning, he never opened the safe.

As for the traces of the filing cabinet being turned over, it was probably discovered after the documents in the safe were stolen.

In fact, top secret documents may have been stolen before this.

Who is that cleaner? Is he still there? Luo Yao asked.

Zhang Xiaozheng was also excited when he heard this. He seemed to have thought of some possibility after Luo Yao's question.
