The Spy

Chapter 101 Footprints Under the Bed
No one had been in there for a few days, so there was some dust on the ground.

Fortunately, the time was short and had no impact on the traces on the ground. There were many messy footprints in the corridor, and it was discovered that several people had come in after Lu Dawang's death.

After Xu Zhanjie arrived, he immediately ordered that no one else should be allowed to enter, otherwise the ground would become even more chaotic.

Holding the camera, Xu Qingyun kept taking pictures.

Every footprint should be photographed clearly. Even if it is damaged and only half of it is left, or even a smaller shoe print, you can still reveal a lot.

After filming in the corridor, Xu Qingyun went into the dormitory alone.

The body was no longer there, and the things inside were placed as they were when Lu Dawang died. There were many footprints on the ground, and Xu Qingyun took photos of them one by one.

Except for the ground, all other positions need to be considered.

Table, bed, bench, wardrobe, washbasin rack, table lamp, sink, even thermos, lamp cord, etc., Xu Qingyun did not miss any details.

Lu Dawang's personal belongings were in the dormitory, including his shoes.

After taking pictures of everything, Xu Qingyun let Yan Ming and others in.

When they went in, they also wore shoe covers and gloves to avoid disturbing the scene.

Xiang Jason accompanied them, standing inside without moving.

He had come here before and found nothing.

"Yan Ming, go search under the bed and on the walls. Fang Laibao, check the roof and cracks in the wall to see if there's anything missing."

Xu Qingyun ordered that everything in the room must be checked carefully, and asked them to come over to help look at it together. It would be a waste of time for him to look at many places alone.

Both Yan Ming and Fang Laibao are careful people, so there will be no problem leaving it to them.

"Yes, team leader."

The two of them took orders and did their respective tasks.

"Team Leader Xiang, has the poison been found?"

"We found out it was arsenic."

Xiang Jason hurriedly replied that arsenic has existed since ancient times and is one of the most common poisons.

"Was there an autopsy? What did he eat?" Xu Qingyun continued to ask.

"There was an autopsy. They ate sesame cakes and pig's head. I'm investigating the source of the food."

After the autopsy, Xiang Jiesheng started to investigate the source of the food. Sesame seed cakes and pork heads were common foods, and Lu Dawang ate them all without leaving any food residue, making the investigation difficult.

"What is the purity of arsenic?" Xu Qingyun suddenly asked.

"purity?"

Xiang Jason was stunned for a moment. He only knew that it was arsenic poisoning, but he really had no idea about the purity of the arsenic.

"Please help me find the autopsy doctor and I'll ask him."

Seeing that Xiang Jiesheng was unaware of the situation, Xu Qingyun didn't say much. The food was ordinary and the poison was common, so it seemed like a premeditated poisoning.

The reason why Lu Dawang could eat the poisonous food without hesitation was either because someone had been targeting him for a long time, or because the food was given to him by someone familiar with him.

All investigation directions must be verified.

"it is good."

He nodded to Jason. Xu Qingyun handled cases differently from others. Unexpectedly, he asked a question he didn't know the answer to right away.

Arsenic has existed since ancient times and had many applications in ancient China. Many historical figures died from this poison.

Arsenic is a colorless, odorless white powder that produces a garlic smell when heated. However, the ancient arsenic extraction technology was immature, and it contained a lot of impurities and produced sulfides.

Sulfide reacts chemically with silver to form silver sulfide.

Silver sulfide has color, gray-black, so in ancient times people used silver needles to test for poison. The silver needles would be inserted into the food. If the food turned black, it meant that arsenic was contained in it.

Xiang Jiesheng didn't understand this, so Xu Qingyun stopped asking him.

"Team leader, come here for a moment."

Yan Ming suddenly shouted, and Xu Qingyun walked over immediately. Yan Ming was searching under the bed, walls and other places in Lu Dawang's room.

This is a dormitory, the possibility of there being a secret compartment is very low, but we have to check it.

Xiang Jason hurriedly followed.

"Look."

Yan Ming had already pulled open the bed and pointed to the wall under the head of the bed, where there were marks left by feet.

Xu Qingyun narrowed his eyes and immediately took out his camera to take a picture.

Xiang Jason was stunned for a moment, then returned to normal.

If they were allowed to check carefully, they would be able to find this trace. However, after the section chief discovered the death, he immediately sealed off the scene and did not allow them to check carefully.

This was not their fault, so Jason had no worries.

"Team leader, there is something going on here."

Fang Laibao suddenly shouted. He was standing on a chair and checking the cracks in the wall on the cabinet, and found something different behind the cabinet.

"Move the cabinet out first."

Xu Qingyun gave the order that it was inconvenient for so many people to climb up together.

Carefully move the cabinet away, and you will find a place on the top back of the cabinet that is obviously different from the rest.

Xiang Jason was stunned again. If they had known that there were so many clues in the room, they should have insisted on searching it instead of blocking it off.

"Scrape it off and send it for testing."

Xu Qingyun did not touch it. From the surface, it was obvious that something had been stuck to it, but now that thing was gone.

Fang Laibao carefully scraped off some of it and put the cabinet back in place.

After carefully checking everything inside and out, Xu Qingyun led his people away.

Intelligence Group 4 has not yet been formally established, but the director has approved it.

Xu Zhanjie's reason was good. Xu Qingyun was the head of the intelligence team at Tianjin Station, and this time he was asked to lead the traitor case. It would not be appropriate to give him the position of deputy team leader in other teams.

Xu Qingyun has made enough contributions, so there is no problem for him to be the team leader.

In that case, let's set up a new group for him.

The personnel of Intelligence Group 4 have not arrived yet, but offices have been vacated for them, including two separate offices and three large offices.

Intelligence Group 4 arrived late, and was given the first floor that no one wanted to use.

This time was different from later generations. People in later generations were lazy and unwilling to climb stairs. As long as the first floor was not damp and had a courtyard, it was more popular than the second or third floors with stairs.

The first floor would be somewhat damp at this time.

Besides, the floor is higher and the view is better. The scenery outside the window is much more beautiful than that on the first floor, which can make people feel better.

Xu Qingyun doesn't care about the office environment, as long as it exists, it's fine.

The first floor is more convenient for him.

There is a separate office for him, and three large offices for the three teams respectively.

There are only three of them in the fourth group of the Military Intelligence Department, and there is enough space for each of them.

Fang Laibao sent the scraped materials to the technical department for testing, while Yan Ming helped Xu Qingyun to clean the photos urgently.

The office had not been tidied up yet, but it was very clean. Xu Qingyun didn't care about these things, as long as he had a place to sit.

"Group Leader Xu."

There was a knock on the door, and Jason Xiang walked in with a man.

The man wore glasses and looked gentle and refined.

"Team Leader Xiang, come in quickly."

"This is Doctor Li from the Medical Department. You can ask him if you have any questions." Xiang Jason introduced that there is a special medical department in the headquarters, which has several professional doctors. Doctor Li has the highest technical level and is usually used as a forensic doctor.

"Hello, Doctor Li."

Xu Qingyun nodded. Doctor Li was a military doctor with the rank of lieutenant, the same level as Xu Qingyun.

He looked at the young man in front of him with a bit of curiosity. He had just heard from Team Leader Xiang that a new fourth group had been formed in the Intelligence Department, and Xu Qingyun, the head of the intelligence team at the Tianjin Station, would be transferred to lead it.

He didn't expect Xu Qingyun to be so young.

"Team Leader Xu, you're welcome. I heard from Team Leader Xiang that you wanted to ask about the purity of arsenic, right?"

Doctor Li sat up straight. He had heard of Xu Qingyun's name many times. Tianjin Station's many great achievements were the result of the hands of this young man.

"That's right." Xu Qingyun nodded.

"We found arsenic in our test before, but we didn't do a purity test. If you want to know, I can try. However, we can't measure the purity from the blood. We can only test it through the residue in the stomach. But because it has been left for a few days, there is no guarantee that it can be fully detected."

"It doesn't matter. It would be best if it can be detected. If not, forget it."

Xu Qingyun replied that the purity of arsenic was not very important, but it was a clue after all, so he asked.

"Nothing, do you have anything else to ask?"

Doctor Li has a very good attitude. He is a technician and does not have much real power, but he is a doctor and others respect him.

No one knows when they will ask Dr. Li to treat them, so doctors should not be offended easily.

"No, thank you for the trip."

"It's okay, it should be."

Dr. Li stood up and went back to prepare to test the residue.

Xiang Jiesheng didn't say anything. The section chief ordered that this case be completely led by Xu Qingyun. He just wanted to see how Xu Qingyun investigated the case.

To be honest, this case is quite difficult.

Lu Dawang is dead. Apart from knowing that he had asked others about the case before, no other information is known. They have investigated Lu Dawang's interpersonal relationships and found nothing unusual.

Food is a clue, but it's difficult to investigate.

First of all, there are many sellers of sesame cakes and pork heads.

There are at least hundreds of them in the city. It is extremely difficult to find the food that has already been eaten among so many stores.

Secondly, what would it matter if we found it out?

It is possible that the store owner was unaware and the product was poisoned by someone else, which means that the clue is cut off again.

As for the newly discovered footprints and sticky marks, they were also weak clues. Xiang Jason admitted that he could not use these things to identify the murderer or find out about Lu Dawang's situation.

Xu Qingyun's case in Tianjin was kept confidential and had never been made public. Except for Yang Wenxu, no one else knew that Xu Qingyun had the ability to see footprints.

Yang Wenxu was the head of the intelligence team. Xu Zhanjie had ordered him to keep it confidential, but he did not tell anyone about it.

"Team Leader Xu, I'm going back to the office first. Please call me if you have anything."

After Dr. Li left, Xiang Jiesheng also left. Lu Dawang was his subordinate, and he had to cooperate with Xu Qingyun.

"Team Leader Xiang, I'll take you there."

Xu Qingyun didn't put on airs. He had just arrived at the headquarters and needed to maintain good relationships with his colleagues.

"Team leader, the technical department is already doing the test and the results will be out tomorrow at the earliest. Is there anything I can do?"

Fang Laibao came back very quickly. The technical department needed time, so he didn't wait there. He ran back to see if there was anything he could do.

The others were not there, and there were only three of them in the four groups. Even the team leader had not been appointed, and there was a lack of help around the team leader.

"Except for the team leader and the section chief, bring in everyone who has been to the scene."

After thinking for a while, Xu Qingyun said softly that the photos were still being developed, but he had already seen them, and now they had to check the footprints at the scene.

Xu Qingyun had a hunch that the effect would not be that great, but the shoe prints on the wall under the bed were the most important clue.

Who would leave marks like that under the bed?

It was obvious that someone had hidden under Lu Dawang's bed. Lu Dawang had a single bed, and when the sheets were spread out, they could indeed block what was underneath.

This person must have rolled under the bed with his feet facing the wall, but because there was no sheet at the foot of the bed, he was afraid of being discovered, so he curled up at the head of the bed, leaving footprints on the wall.

"Yes, I'll go right away."

Fang Laibao left happily, as long as he had something to do. This time it was a case of traitor, and it was at the headquarters.

If done well, it will definitely be a great achievement.

"Team leader, all the photos have been developed."

Yan Ming brought the photo to the office. Xu Qingyun took it and put it aside for the time being.

He took the photo, and you can tell how many shoe prints there are without even looking at it.

Xu Zhanjie, Xiang Jiesheng, Yang Wenxu and others all have them.

In addition, there are three other people, and Fang Laibao is looking for them.

"Go and find out about Lu Dawang's interpersonal relationships, both inside and outside the station."

Xu Qingyun instructed that Lu Dawang was poisoned to death, and the food was sesame seed cake and pork head, and these two things tasted really good together.

Adding a little garlic juice can completely cover up the smell of arsenic produced by heating.

There are only two possible situations where someone poisoned the food. One is that the food vendor sold the poisoned food to Lu Dawang and successfully poisoned him to death.

Secondly, someone gave Lu Dawang food, and Lu Dawang died after eating it.

If it was the latter, since Lu Dawang could eat without any worries, he must be someone with whom he had a good relationship.

Lu Dawang was from Zhejiang Province. His family was poor and he only finished elementary school. However, because of his good memory, he was noticed by the Military Intelligence Department, who recruited him and trained him in Hangzhou to become a professional agent.

I was just assigned to the Intelligence Department last year and have been working here for less than a year.

His usual performance is nothing special, his relationship with his colleagues is average, and his personality is rather dull, but his memory is really good, and he can completely remember things after reading them once.

Lu Dawang doesn’t have many acquaintances in Nanjing, but he has a good relationship with a few classmates who were assigned there together in Hangzhou.

There are dozens of students graduating from the intelligence major in Hangzhou every year. Not all of them will be assigned to the headquarters. Each branch station will also have to be assigned to a certain point. Xu Qingyun noticed that last year a total of six students were assigned to the intelligence department, all of whom are in the intelligence department, with two people in each group.

"Yes, team leader."

Yan Ming ran out and bought some good cigarettes.

This guy is very good at flattering people. Even if he doesn't know the person, he can become friends with them in just a few words, and make people feel his sincerity.

He is the most suitable person to do this.

"Team leader, they are coming."

Fang Laibao quickly brought three people to the office, one of whom was Lu Dawang’s roommate. He was in the same group and team as Lu Dawang, and he was the first to discover that Lu Dawang was dead.

He ran out to call for help, and someone came from the next dormitory. Someone called their captain, and the captain and Xiang Jiesheng and the others went there together.

The three footprints on the ground were left by the roommate, the captain and another person who had entered.

"Hello, Team Leader Xu."

The captain greeted us first. He was not very old, only twenty-five years old. The Military Intelligence Department was established not long ago, and except for the station chief, section chief and others, most of the people there were very young.

"I asked you to come here to ask you something. Don't be nervous. Come and sit over here."

Xu Qingyun politely took them to the sofa. He had just sprinkled some dust on the ground. After a few people passed by, their footprints were immediately left on the ground.

It was indeed the three of them.

The number of people and the footprints match.
