According to Sokov's vision, he first investigated whether Nayi had contact with suspicious personnel after leaving the Kremlin every day, so as to confirm whether he was suspected of collusion with the enemy, and then formulated a next action plan. But he did not know that if he wanted to follow his plan, this matter should be handed over to Gerchkov, a senior detective, rather than an internal affairs department staff like Arina.

As soon as the sky got dark, Arina hurried to Sokov's office and said excitedly: "Comrade Major, I have figured it out. There is indeed something wrong with that Nayi."

Sokov was delighted and asked, "Alena, have you investigated at Nayi's house?"

"Yes." Alina nodded and replied, "I have taken people to Nai's house, asked his sick mother and his neighbors, and they all said that Nai goes home every day."

Hearing this, Sokov felt full of loss. Unexpectedly, there was something wrong with his judgment. Nayi went home every day to take care of his sick mother.

Just as he was about to say something, Gerchkov, who was sitting behind the desk next to him, walked over and said to Sokov with disappointment: "Major Sokov, although the people I sent to monitor Nayi have not come back yet, I don't think it is necessary to wait for his report."

As soon as Gerchkov finished speaking, a sound of a report came from the door, and then a policeman walked in. Sokov knew him at a glance. The policeman was the one who was waiting for Nayi to come out of the small gate of the armory, Gerchkov arranged for the policeman outside the small gate of the armory.

Seeing the police arrived, Gerchkov spoke first and said, "What's the result? Did Nayi go home by himself?"

"Comrade Major." Unexpectedly, the police shook his head and said, "I have not seen Nayi come out until now. Since you asked me to perform a surveillance mission, I cannot go forward and knock on the door to ask the soldiers guarding the door, so I can only come back and report to you."

"Strange, this Nayi did not appear today?" Gerchkov said with a frown: "Where did he go?"

"Major Sokov," Alina's voice rang out: "This is exactly what I want to report to you, and Nayi is currently staying in Rubyyanka's prison."

"What, Nayi stayed in prison?" Sokov asked in shock, "When did he go to prison?"

"Just two hours ago," Alina said proudly, "I personally led him to arrest him."

"You have arrested him?" Sokov asked displeasedly: "Lieutenant, who allowed you to do this?"

"Major, please listen to my explanation." Seeing that Sokov was showing signs of getting angry, Arina quickly explained to him: "Although I learned that through investigation at Nayi's house, he had to go home to take care of his sick mother every day. However, the time to go home is uncertain. It usually only takes more than twenty minutes, and sometimes he has to wait three or four hours to go home. I suspect that he must have seen someone else on the way home, so he reported the matter to his superiors. After receiving my report, he immediately arranged a man to arrest Nayi secretly."

"Nayi has been arrested secretly?" The police officer in charge of surveillance said in surprise after hearing this: "But I waited six or seven hours since I received the order to leave, but I never saw Nayi coming in and out. Where did you arrest him?"

"This matter was arranged above," Arina saw the change of Sokov's expression and guessed that he was worried about something, so she explained to everyone: "It was sent to other places to arrest people, but did not disturb anyone in the armory."

Sokov was indeed worried that the actions of the Ministry of Internal Affairs would alarm the task force and let the task force go to waste. After hearing Alina's explanation, he couldn't help but breathe a sigh of relief, and then asked: "Since he was imprisoned in the prison of the Ministry of Internal Affairs, when do you plan to interrogate him?"

Arina took out a few pieces of paper from her shoulder bag, put it in front of Sokov, and said proudly: "This is his confession!"

Sokov grabbed the confession in front of him and quickly browsed the content above.

In his confession, Nayi said that he was instructed by Babushkin, the head of the armory. After leaving the Kremlin every day, he went to a coffee shop and chose the innermost question. He put the note Babushkin gave him under the table with tape. If the other party responded, a waiter would come to him and put a bill on the opportunity to order him.

After reading the confession, Sokov breathed a sigh of relief, feeling that he was not wrong. Major Babushkin was indeed a problem. And that cafe was a point of contact with the outside world.

After handing the confession in his hand to Gerchkov, Sokov asked Alina curiously: "Alena, now it is basically certain that the cafe is a secret contact point. What measures have you taken?"

Arina smiled and said, "All the people in the coffee shop have been arrested. Now ours has been replaced. If any German agents go there to get information, they will be arrested on the spot."

"I really didn't expect that the Ministry of Internal Affairs was so quick." After reading the confession, Gerchkov said with emotion: "According to our prior plan, it will take at least three or five days to crack the lurking enemy special organization. Unexpectedly, the Ministry of Internal Affairs directly removed their contact points as soon as they took action."

"I wonder what the information Nayi sent today?" Sokov asked.

Arina did not answer immediately, but said to the police officer who was performing the surveillance mission: "Comrade Police, you are not a member of our task force. The next thing you say is not something you can hear, you can go out first."

After hearing this, the police turned around and walked out without saying a word.

After closing the door, Arina returned to Sokov and Gerchkov and said with a serious expression: "In today's information, Comrade Stalin will lay flowers at the cemetery of the nameless martyrs behind the Kremlin at noon the day after tomorrow. Major Babushkin asked German agents to arrive at the side door in a truck with tarp at 11:30 and honked three times. After hearing this, he would find a way to open the side door and let them enter the Kremlin."

After hearing this, Sokov looked at Gerchkov and came to a bold conclusion in his heart: "Comrade Major, it seems that the German agents plan to assassinate Comrade Stalin the day after tomorrow."

"Yes, it's true." Gerchkov asked with a serious expression: "What should we do? Do you ask Comrade Stalin to change his original plan?"

"I think it's definitely not possible," said Alina. "After the interrogation results came out, I reported to my superiors as soon as possible. But my superiors sent Comrade Beria's order, asking us to find a way to eliminate the German agents who infiltrated the Kremlin when Comrade Stalin pays homage to the unknown martyrs."

"If we do this, wouldn't Comrade Stalin take the risk?" Gerchkov was shocked and sweated in a cold sweat after hearing this: "Although we can set up an ambush in advance, wait for the German agents to sneak in and catch them all in one go. But if Comrade Stalin really goes to the cemetery of the Unknown Martyrs to pay tribute, wouldn't it be life-threatening?"

"Gay Major." Arina looked at Gerchkov and said expressionlessly: "This is Comrade Belia's meaning. You don't need to discuss and just execute it."

Sokov's reaction was much calmer than Gerchkov. He knew very well that since Belia dared to issue such an order, he would definitely make arrangements in advance. So he turned to ask Alina: "Alena, I wonder how Babushkin planned to put German agents in?"

"According to Nayi's confession, they plan to kill the warriors guarding the goal the day after noon, open the small door and let the German agents come in." Alina said: "And they arranged for them to lurk near the cemetery of the unknown martyrs, and immediately launch an attack as soon as Comrade Stalin appears."

"Where is Major Babushkin, what are you going to do with him?"

"Comrade Belia said that in order to avoid alarming the enemy and alarming the enemy, he cannot be moved for the time being."

"No, this person cannot stay." Sokov interrupted her afterwards without waiting for Alina to finish her words, "You have arrested Nayi secretly. If he finds that Nayi has not come back to work tomorrow morning, he will definitely be suspicious. Although he went to the cafe this time to pass messages to the outside world, who can guarantee that he does not have a radio station in the armory? If he really has a radio station, once he finds Nayi missing, he will definitely contact the German agents outside and cancel the assassination."

After hearing Sokov said, Gerchkov nodded and echoed: "I think Major Sokov's concern is completely correct. Although Babushkin is contacting the outside world through Nai, if he really has a radio station hidden in the armory and finds something wrong, he will immediately send a telegram to the outside world to warn, and then our deployment will fail. It will be very difficult to catch these German agents in the future."

"So, we need to arrest Babushkin immediately?"

"Yes." Sokov nodded vigorously and said in a positive tone: "Lieutenant Arina, please go back and tell your superiors to secretly arrest Major Babushkin. At the same time, you have to find someone to tell the other people in the armory that Babushkin and Nayi will not return to the armory in a short time because their superiors have other arrangements. In this way, even if there are Major Babushkin's accomplices in the armory, there will be no news."

"Okay, Major." After hearing Sokov's story, Arina nodded and said, "I will go back and report to my superiors immediately to see how they think about it."

"As soon as there is news, come back and report to us," Sokov reminded: "so that we can have a clear idea."

After Arina left, Sokov said to Gerchkov: "Comrade Major, please give me the Kremlin map."

Gerchkov walked to the filing cabinet beside the wall, opened the cabinet door, took out a file bag, came back to Sokov. After opening the file bag, he took out a floor plan from it and placed it in front of Sokov.

Sokov stared at the floor plan for a while, found the cemetery of the nameless martyrs located in the Kremlin, pointed at the city wall next to it, and said to Gerchkov: "I think we can arrange two sharpshooters on the city wall to kill the agents who are most dangerous to us in the battle."

"Major Sokov," added Gerchkov. "There are 18 towers in the Kremlin, two of which are located around the cemetery of the Unknown Martyrs. For the sake of safety, I suggest that two sharpshooters be placed in each tower, so that the destruction of German agents will be greater."

"No problem," Sokov replied very readily: "Then arrange two sharpshooters in each of these two towers to help us eliminate the German agents who are fighting stubbornly."

After ten o'clock in the evening, Arina appeared in the office again and reported to Sokov and Gerchkov: "The two major comrades, Major Babushkin of the Armory, have been secretly arrested, and like Nayi, they were imprisoned in the Ministry of Internal Affairs Prison in Rubyanka."

Upon learning that the secret arrest was successful, Gerchkov couldn't wait to ask: "How is it, have he been interrogated?"

"Yes, he has been interrogated."

Sokov saw a depressed expression on Arina's face and guessed the result: "Did he confess nothing?"

"Well, you guessed it right." Alina said with a sad face: "We used a lot of methods on him, but he just gritted his teeth and refused to say a word. The interrogation is still going on, and I'm worried that you are anxious, so I came here to chat with you."

"We have roughly grasped the assassination time and plan of the German agents." Although he learned that Babushkin was very strict and could not confess, Sokov was not worried at all. He said to the two: "We just need to set up the trap in advance and wait for the Germans to take the bait."

"Who will open the door then?" Gerchkov asked with some concern: "I am worried that if I find someone to open the door, the German agents may see the flaws, and then our plan will be discovered."

"I think I'll be responsible for opening the door."

"What, are you going to open the door for the German agent?" Arina heard Sokov say this and immediately started yelling: "No, this is absolutely not possible. It's too dangerous. If the German agent finds something wrong and takes the risk, you will be in danger of your life."

Sokov was quite moved in the face of Alina's concern, but he still said firmly: "Lieutenant Alina, thank you for your concern. However, I think it is best for me to open the door to the German agents. Once any emergency occurs, I can also deal with it based on the actual situation at that time."

Seeing that Arina was not speaking, and Gerchkov seemed to want to persuade him, he quickly raised his hand and said in an unquestionable tone: "Okay, this matter is settled. The day after tomorrow at noon, I was responsible for opening the small door next to the armory, putting the German agents outside in, and taking them to collect weapons. You two are responsible for setting up defenses, and when the enemy enters our trap, they will immediately open fire and destroy them."
