There is no need to consider if it is more than 2.5 kilometers. Even if they are riding a bicycle, they must make this call within ten minutes. This is an emergency notification. Wasting one more minute may cause irreparable consequences.
Five minutes is the most likely.
In this era, the speed of bicycles in the city is about four minutes per kilometer. The person who reported the news would not ride very fast. Too fast would easily attract the attention of the patrol police. That’s why Chu Lingyun drew these three circles. The person who reported the news basically
Within the scope of these three circles.
It is a pity that we cannot confirm the time when Nanjing received the notification, otherwise we can better determine the scope.
The place where the car was lost is right at the edge of the first circle.
"Team leader, I'm back."
Loach knocked on the door and came in. He had sent Ren Han's fingerprint to the technical department. Through comparison, it was found that it was not the half of the fingerprint extracted from the car.
Ren Han's suspicion can basically be ruled out, and he also gave them good news. The half of the fingerprint behind the bicycle lock was most likely left by the informant.
"Loach, please take someone to check how many businesses sell and use paint in this largest circle."
Chu Lingyun ordered that the scope has been decided, and the next step is to investigate. The comparison of the technical department has not yet produced the results, but it will not affect their early investigation.
"Okay, just wait for my good news."
Ni Loach happily accepted the order, and the busier he became, the more fulfilling he became. This time he was investigating espionage again. Now that Shen Hanwen and Chu Yuan were not in the team, he was the first to get the most, and all the tasks were assigned to him.
In this way, his contribution will be greater.
"Ring ring ring."
Not long after Loach left, the phone on the table rang. When he picked up the phone, Team Leader Hu's voice came over: "Team Leader Chu, the paint comparison results you sent are out. I have asked someone to send the report to you.
Gone."
"Thank you very much, Team Leader Hu. If we can catch a spy this time, I will definitely help your technical department take credit."
With the results of the paint, the direction of the investigation will be clearer. Chu Lingyun gave a timely favor. Team Leader Hu grinned: "It's just a little effort, Team Leader Chu doesn't need to pay too much attention."
After saying that, as if he was afraid that Chu Lingyun really wouldn't ask for credit for them, he hurriedly said: "If you really catch a spy, just give us a nice word when the time comes. You also know that our technical department usually has no chance of making meritorious deeds.
Master, if it weren't for Team Leader Chu this time, we wouldn't have such a good opportunity."
Chu Lingyun smiled: "Don't worry, your contribution is indispensable for solving the case."
Two minutes after hanging up the phone, someone from the technical department sent him the paint comparison results.
According to the laboratory comparison of the technical department, two paints are similar to those found on the bicycle seat, and the other paints are not consistent.
If you want to determine which of these two models are exactly the same, you have to wait for the test results.
It was a good result to compare the two paints. Chu Lingyun noticed that the prices of these two paints were not low. Among all the paints purchased and compared, the prices ranked second and third.
There are more than a dozen kinds of paints, and this ranking is considered very high.
"Wang Sheng, I have a new mission for you."
After someone sent the comparison results to Loach, Chu Lingyun called Wang Sheng again.
Wang Sheng over there hurriedly replied: "Sir Chu, no matter what task you give me, I promise to complete it for you."
In fact, the last time I found Jiang Binghui, Wang Sheng was about to be promoted in the New Year. Although the police were not under their control, it was very simple to say hello and promote a deputy chief to the sergeant in the New Year.
It was Chu Lingyun who temporarily suppressed Wang Sheng's promotion. He had just been promoted to deputy chief of police not long ago. It would not be a good thing if he was promoted too quickly. Chu Lingyun still had to look at his performance.
Wang Sheng's performance has been good recently. He has made meritorious service in the Marine Police Bureau's investigation, and he helped him find Du Fang's weakness before. If he makes meritorious service again this time, he can be considered for promotion.
If you want your horse to run fast, you must have enough fodder.
"Check, who are the masters of lockpicking in the whole city of Nanjing? Regardless of whether they are thieves or not, as long as they have strong lockpicking ability, they should be asked."
Chu Lingyun assigned him a task. Ren Han was not a spy, but the person who reported the news stole his car. He still thought of stealing the car when reporting the news urgently. This person has a very strong psychological quality.
The location where he stole the car may be very close to where he is.
But only the location is not enough, we also need to determine who stole the car. Niluo investigates the clues about the paint, and the clues about the car theft are handed over to Wang Sheng for investigation. A two-pronged approach can make it faster.
"Don't worry, I will give you the result of this little thing tomorrow at the latest."
Wang Sheng claimed that he was just investigating someone who knew how to pick locks. It was really not a big deal for the police.
No matter how senior you are, sometimes it is very difficult to find lost things, but the police are different. They are very familiar with everything in the area. As long as it has been stolen, if you hand it over to the police, they will definitely find it for you.
.
The police in this era have an unusual relationship with the gangsters on the streets.
……
"Captain, this is a new clue that the team leader asked me to send you."
Loach's team members finally found his captain, and he sent a comparison report of the paint.
“With a clear paint type, it’s easier to investigate.”
After reading the comparison report, Loach grinned. He had a scope and something to investigate. All he had to do next was to do his best. Finding information was what he was best at, and he could find out the results quickly.
In the evening, Loach came to Chu Lingyun's home to give a report.
"Team leader, in the largest circle you drew, there are a total of nine firms selling these two types of paints. Most of their customers are carpenters or furniture factories. I checked their sales orders and found that these two types of paints are sold.
There are twenty-seven painters."
"Of the twenty-seven, nine are carpenters, and out of the fourteen furniture factories or stores, only four people buy them individually. According to the store, they touch up the furniture or other things themselves."
p>
It is not new for individuals to buy paint. In later generations, some people also bought and painted it themselves.
Both individuals and businesses are the targets of the investigation. Twenty-seven companies are not a large number, but the number of people is not necessarily small.
This chapter is not over yet, please click on the next page to continue reading!
There may be more than one person in a furniture store or factory.
"How many places are there where Ren Han lost his car?"
Chu Lingyun took out the map and asked. Niyi immediately lay down, pointed at the place where Ren Han dropped the car and said: "There are two merchants selling paint and six factories nearby. There are many furniture factories in this area, it is a small concentration
Yes, two people who bought paint alone also live here."
Two merchants, six factories, plus two people, there are ten investigation targets in total. They are the key targets of this investigation.
"Tomorrow you will investigate them, mainly their people, and also check to see if there is anyone with the same body shape as the clerk said. If so, mark it out and focus on verification."
Narrow down the scope and investigate secretly. As long as the person who reported the news is still in Nanjing City, Chu Lingyun believes that he will be able to find him. No matter how cunning the fox is, as long as he leaves traces, he will not be far away from being caught.
p>
"Okay, team leader. Zhao Hua, I haven't finished copying it yet. I'll send it to you when I finish it."
Loach responded, while Chu Lingyun shook his head: "There's no rush, business matters are important. Find the person first, don't waste time on Zhao Hua."
The money is very good, and Chu Lingyun wants it very much, but time is running out now. It is most important to catch the person who reported Liu Dazhuang as soon as possible and determine the identity of Liu Dazhuang's traitor.
"Don't worry, team leader, I won't delay the business."
Loach chuckled and said that he would carry out the task well and make money without delay.
Wang Sheng came to the Military Intelligence Office early the next morning.
Whether he is in Wuhan or Nanjing, every time he comes to this unit, he will feel a little scared.
Now he is the deputy chief of police and knows more about the Military Intelligence Department. The power of this department is really amazing, especially the police, who can only act with their tail between their legs in front of this unit.
Even though he is just a deputy chief, many people in the police station now know that his backend is in the Military Intelligence Division, and they are very polite to him. No one in the police station dares to offend him.
"Sir Chu, according to your request, I have identified the person."
Arriving at Chu Lingyun's office, Wang Sheng immediately bent down and placed a list on his desk.
"More than three hundred people, is that much?"
Seeing the dense list, Chu Lingyun was stunned. There are so many lockpicking masters in Nanjing?
Wang Sheng nodded: "It's quite a lot. There are many people in Nanjing, and many hooligans know how to steal things. There are quite a few who know how to open locks."
This still only requires lockpicking masters. If you want to check for thieves, the number will be much greater, definitely more than a thousand.
Especially in crowded places such as train stations, docks, and shopping malls, there are countless thieves.
"Leave it here."
Chu Lingyun glanced at the list. Not only did they have their names, but also their residences, and some were marked with remarks. This list was very detailed, and it could be seen that Wang Sheng had put his heart into it.
"Yes, Chief Chu, I'll leave first."
Wang Sheng said goodbye and left. Chu Lingyun compared the map to find out the number of people living in the circle, especially near the place where the car was lost.
There were more than fifty people in the circle, which was quite a lot, but there were not many people near the missing car, only eight.
These lists were also sent to Loach.
"Team leader, we found the person."
At noon, Loach came to the office excitedly, and Chu Lingyun raised his head.
"According to the unlocking list you gave me, team leader, I found two people working in the furniture factory among the eight people. One is named Wu Da and the other is named Hou Laosan. Both of them have been exposed to those two types of paint.
”
"I called the hotel clerk over and secretly looked at them. The clerk finally said that Hou Laosan looked like the person who made the phone call.
"Then I investigated Hou Laosan's whereabouts yesterday, and he was indeed not in the factory during the time of the phone call. After that, I personally searched Hou Laosan's home and found the hat. The hotel clerk confirmed that it was the time of the phone call.
The one I brought with me, but the blue robe was not found. It may have been destroyed by him."
"Did you find anything else?" Chu Lingyun asked.
"No, but according to my secret investigation, I learned that Hou Laosan's lockpicking skills are very good. He has also taught several apprentices, which are among the best in Nanjing."
Niluo shook his head. He was a master of unlocking, had been exposed to paint, and was not in the factory when he made the call. There was indeed a serious suspicion.
However, Japanese spies are cunning, and Chu Lingyun has never looked down upon them. I always feel that it is a little easy for the third child to be exposed at this time.
"Team leader, do you want to arrest someone?" Seeing that Chu Lingyun didn't speak, Loach hurriedly asked.
"Don't worry, who did he come into contact with yesterday and what did he do? Have you investigated clearly?"
Chu Lingyun shook his head and said, if Hou Laosan is the one who called Liu Dazhuang, then someone must have informed him of this information.
Whether it's sending a notification, calling someone, or calling someone on the radio, it's always one of them.
The possibility of sending someone to notify is less likely. Not to mention wasting time, it would be better to send someone to call Liu Dazhuang directly. That would be more trouble-free.
As for the phone calls, they are not safe. If the Military Intelligence Department wanted to investigate, it would be easy to find their phone numbers.
Therefore, radio notification is most likely. If this is the case, Lao San must have a radio station at that time.
But they are in Nanjing, not their territory. The radio station cannot be turned on 24 hours a day. How did Shanghai notify them so accurately? The problems here must be investigated clearly before action can be taken.
If you act rashly, if the caller is not Hou Laosan, it is very likely that the real caller will not be caught.
Loach was startled and quickly replied: "I haven't checked who he has been in contact with yet. I will check now."
"I'll go with you."
Chu Lingyun stood up. The more detailed the investigation, the more likely it is to find the person who made the call.
Hou Laosan has a serious suspicion, and the investigation against him cannot be stopped. However, there is no absolute certainty that Chu Lingyun will not arrest anyone, lest something goes wrong and the real spy escapes.
"Team leader, that's the factory where Hou Laosan works."
In an alley, Ni Loach pointed to the gate in the distance and said to Chu Lingyun, this is a small furniture factory, similar to a family workshop. There are only seven people in the factory including the boss. Hou Laosan is a carpenter in the factory and his craftsmanship is good.
.
Hou Laosan is 43 years old this year. He was a gentleman in his early years and was arrested several times. Later, he quit and learned the carpenter's skills. Now his life is pretty good.
"Are you sure Hou Laosan has been living in Nanjing?"
Chu Lingyun asked, Loach was slightly startled, and immediately understood what Chu Lingyun meant.
If Hou Laosan has been in Nanjing and proves to be a local, then he cannot be Japanese. People like Zhao Pinsong are extremely rare, and it is difficult for another one to appear.
Moreover, Hou Laosan was not trafficked, he has parents.
"It is currently confirmed that he has been in Nanjing. Team leader, is it possible that Hou Lao San is a stand-in like Yang Jian, asking him to make a call at critical moments and only use it once?"
Loach expressed his guess that Hou Laosan was not Japanese, but he might have been bribed to help the Japanese.
Ni Loach's thoughts were different from Chu Lingyun's. No matter how he looked at Hou Lao San, he looked like the person who called Liu Dazhuang.
"No." Chu Lingyun shook her head affirmatively.
Liu Dazhuang's identity is very important. The Japanese will never arrange for a stand-in to make emergency evacuation arrangements. In that case, there will be too many variables.
Once Hou Laosan fails to complete the task, Liu Dazhuang may be arrested at any time.
The person who called Liu Dazhuang was definitely Japanese.
