With Sergei's guidance, Kester soon found the password book and list hidden in the filing cabinet in the ruins of the post office. To be safe, Kester specially opened the items after getting them, and then returned to the command center to report to Sokov.

Sokov picked up the password book and flipped it out. It was all numbers that he couldn't understand. He called a communications consultant and ordered him to give the password book to Zhukov, and then began to look through the list of the lurkers.

The list of lurkers was written on three sheets of paper. Sokov counted briefly and there were 72 people in total. Behind each name was where they lived and the profession they were engaged in.

Sokov saw Avdiev's name behind him, and there were indeed a soap factory marked. In addition to him, there were two other people. One was the deputy factory director who had been killed, and the other was the head of the production department. No wonder Sergei was able to find him so easily, and his detailed address was included on the emotional list.

The old man Sergei's name is also on it, and the latter is marked as a telegrapher of the Post and Telecommunications Bureau.

Next, the names of the two arrested warehouse managers.

When Sokov saw that a sergeant in his army guard camp was also on the list, he immediately understood why the Germans pretended to be Selyosci. Because they knew that they had a close relationship with Selyosci through this inside line, and they guessed that such an important action as saving Zhukov would definitely send this confidant to take action.

"Comrade Commander, what's going on with this Lieutenant Bohr?" Vitkov and Sokov ordered people to arrest the sergeant, pointed to the name on the top of the list, and asked in surprise: "Are there any Germans lurking among the enemies in the city?"

There are addresses and occupations behind other people's names, but Lieutenant Bohr only has one name and there is no comment afterwards. Sokov could only hope to open the gap from Sergei, so he ordered: "Go bring Sergei!"

After Sergei arrived, Sokov said, "According to what you did, it is not an exaggeration to shoot you immediately. But I plan to give you a chance to make meritorious service. Whether you can survive depends on how you cooperate."

After Sergei was caught, although he readily admitted that he was a spy sent by the Germans to the city, the important thing was to avoid talking about it. Today he decided to take a risk to take a gamble and hand over the list of lurkers he had hidden to see if he could change his chance to survive. He heard Sokov say this and immediately realized that his choice was correct. He nodded quickly and said, "Comrade Commander, if you want to know, just ask. As long as I know, I will answer truthfully."

"Who is Lieutenant Boer?" Sokov asked, "Is he German?"

"Yes, he is German, but he speaks Russian very well," Sergei said. "If he didn't say he was authentic German, I would have thought he was Russian."

"Why doesn't he have an address?"

"Comrade Commander," Sergei said honestly: "This Lieutenant Pole, who usually wears an army captain uniform, wanders around the streets every day, taking the opportunity to spy on your military information. You also know that in many places in the city, there are military restricted areas, and I can't get in at all. At this time, Lieutenant Pole takes action. He pretends to be passing by, finds the sentry standing guard at the door to borrow fire, and then schews from the other party during a chat. He found out the news about Zhukov's future Lugansk in this way."

After figuring out how the enemy discovered Zhukov's whereabouts, Sokov nodded slightly and then asked, "Then where can we find him?"

"I don't know." Sergei shook his head and said, "It's usually him who comes to me, but he never tells me where he lives."

After hearing Sergei's explanation, Sokov finally understood why every lurker had an address behind him, but this mysterious Lieutenant Bohr did not. He always took the initiative to find Sergei.

"What does he look like?" Sokov asked.

"Comrade Commander, his height, fat and thin are similar to yours, with a square face, and his face is very clean." Sergey tried hard to think about Lieutenant Boer's characteristics, but found that the other party did not seem to have left any deep impression on him: "Every time he appears, he wears a mortar short leather coat and a cotton military cap..."

"It's hard to find this." Hearing Sergei say this, Vetkov began to murmur: "Luhansk can find at least a few thousand such people here."

Sokov also felt that what Sergei said was too general. If he didn't draw puzzles, finding such a person would be like looking for a needle in a haystack. However, he still asked with a lucky mentality: "Do he have other characteristics?"

Sergei frowned and thoughtful. After a long time, his eyebrows suddenly raised up and said excitedly: "I remembered it. When he walked, he liked to use his left hand to beat his back. According to my analysis, he must have been injured on his back."

This is a very interesting feature. Even if he walks among a group of people who look similar to him, as long as he beats his back with his left hand while walking, it will still be very eye-catching. Thinking of this, Sokov recorded this in his heart. He felt that the other party's habitual movement might expose him quickly.

After someone took Sergei away, Sokov had already figured out the truth of the whole thing. After the German lieutenant Pol lurking in the city, he immediately asked Sergei to send a report to his superiors and asked them to send paratroopers to carry out sneak attacks. At the same time, he ordered people to provide enough Soviet uniforms for the paratroopers sneaking into the city in the post and telecommunications bureau in the north of the city. Moreover, after the first group of sneak attacks failed, they used the information provided by the inside line of the Guard Division guard battalion to pretend to be Serrysha and tried to rush into the hotel where Zhukov was. If it hadn't been made in advance, it might have turned into a big mistake.

"Comrade Commander," Witkov asked Sokov: "We don't know much about Lieutenant Pole, how can we catch him?"

"Chief of Staff, immediately give orders to each division." Sokov knocked on the table with his finger for a while, suddenly thought of a good idea and quickly ordered Vitkov: "Order all lieutenant-level officers to stay in their respective defense zones from now on, and no one is allowed to go out. If anyone violates, the patrol team has the right to arrest them on the spot."

"Comrade Commander, why is this?" Witkov asked in confusion.

Sokov smiled faintly and replied, "Comrade Chief of Staff, don't you understand yet. If we lock all the lieutenant-level officers in the camp, then the lieutenant-level officers appearing on the street..."

Witkov was also a smart man. When Sokov said this, he suddenly realized: "I understand. If we lock all the lieutenant-level officers in their respective camps, if there are lieutenant-level officers wandering around on the street, it means that he is a German disguise."
