Lao Hou said at this time: "So that's the case, the headquarters sent them back to Stone City, or to find out who is the traitor." However, we have also thought of some ways to screen it before, but this traitor is very cunning and does not show any flaws, I am afraid that after the two of them return to Stone Town, we will still not be able to identify them, and if that traitor stays in Stone Town, it will be very destructive to our work. ”

"So I thought about it and thought it would have to be a two-pronged approach." Minister Pan said slowly.

"A two-pronged approach? How is a two-pronged approach? Lao Hou didn't understand what Minister Pan meant, and asked with a frown.

Minister Pan held out two fingers and explained: "The two-pronged approach is to use two different means to screen. First, Yuan Shiheng is the contact person of the traitor, and we have to find a way to keep an eye on him, especially his daily activities. Since that traitor has returned to Stone City, it is estimated that he will think that he has passed our review, and he will definitely have some activities, and he will also contact Yuan Shiheng. As long as we can stare at Yuan Shiheng to death, see how he contacted the traitor, and see if we can find out who the traitor is. ”

Lao Hou thought for a while and raised his objections: "We don't know the contact information between Yuan Shiheng and that traitor, how can we find out?" Know that there are many ways to make such a secret contact, such as making phone calls or using dead mailboxes. If it is a direct phone call, do we still have to keep tapping Yuan Shiheng's phone? This is a bit difficult to do, and we don't have much power in the telephone office. And if Yuan Shiheng's contact with the traitor was carried out by telephone, the Japanese would definitely protect Yuan Shiheng's phone closely. And if Yuan Shiheng and that traitor are in contact through the dead mailbox, we can keep an eye on Yuan Shiheng. However, it is not a good choice to follow an old agent like Yuan Shiheng, it is easy for him to detect, and the comrades we send to follow him may also be in danger at that time. It is very likely that Yuan Shiheng will set a trap to arrest the comrades who are following him after he realizes that he is being followed, so that the underground party organization in Stone Town will be somewhat dangerous. ”

Of course, Minister Pan knew that what Lao Hou said was practical difficulties, but he had his own ideas and methods, and he put forward his own thoughts on Lao Hou's objections: "Lao Hou, I admit that there will indeed be great difficulties in this matter objectively. But this is our job, and we should not be held back because of objective difficulties. In the light of the difficulties you just mentioned, why don't we think about the problem differently? If Yuan Shiheng and the traitor use the phone to communicate, we can keep an eye on Cheng Kun and Tian Jie to see if they usually call often. And I think it is less likely that they use the phone to contact this way, telephone calls sometimes have limitations in transmitting messages, many times it is very likely that they can't explain things in detail and clearly on the phone, and it is even more impossible for them to meet each other, now that Yuan Shiheng's identity has been made public, he shouldn't take the risk of the traitor being exposed to meet the traitor rashly, because it is easy for us to find out. ”

After a pause, Minister Pan continued: "If Yuan Shiheng and that traitor were in contact through the dead mailbox, we don't have to track and monitor Yuan Shiheng, just like you are worried, it will be easy for Yuan Shiheng, a veteran spy, to detect." Let's start by monitoring Cheng Kun and Tian Jie, tracking and monitoring them, to see if there are any abnormal movements in their usual activities. Here's a way. ”

Lao Hou nodded and continued to ask, "Okay, this is a solution." So what's the second option? ”

Minister Pan bent a finger and said, "The second two-pronged method can only lead the snake out of the hole!" took advantage of the task assigned to us by the Yan'an headquarters under the leadership of the Southern Bureau this time, deliberately revealed the news to Cheng Kun and Tian Jie, tested the reaction of Yuan Shiheng and the Japanese, and finally identified who was the traitor. ”

Lao Hou asked with some hesitation, "Take advantage of this real mission?" I don't know the details of this mission yet. However, judging from your description, I feel that this mission is not trivial, and if the mission fails in order to screen out the traitors, then we will not be able to explain it to our superiors and headquarters. By the way, what exactly is the mission this time? ”

Minister Pan walked to Lao Hou's side and sat down, and said softly: "Our party is going to hold an important meeting in Yan'an recently, and according to the instructions of the Central Committee, members of the Central Committee from all over the country must go to Yan'an to attend the meeting. One of the important leaders would pass through Stone Town and make a detour to Yan'an. The task given to us by the headquarters and superiors is to ensure the absolute safety of this leader on the road, and the route has been arranged on the Heyu Province side, and Stone Town is a traffic artery, and it is also the only way for this leader. I have called you back from Stone Town today to announce this mission to you, and to ensure that this leader passes through Stone Town safely and without a sound. ”

When Lao Hou heard this, he was shocked and said: "This task is so critical, Lao Pan, are you sure you want to use this task to lure out that traitor?" It's too risky! I can't agree with you! ”

Minister Pan patted Lao Hou on the shoulder and explained, "Don't worry, of course I won't let this leader do anything in Stone Town." I mean that after this leader arrives in Yan'an safely through Stone Town, you will reveal this news to Cheng Kun and Tian Jie respectively to see how they will react. ”

Only then did Lao Hou relax and said: "This is about the same, and it is the safest way to wait for that leading comrade to arrive in Yan'an safely before revealing the news." You're really scared! ”

Minister Pan smiled and asked, "How is it?" Lao Hou, you already know the task, are you absolutely sure to complete this task? Don't be in a hurry to answer me, think carefully about how to accomplish this important task, especially in terms of details, and use all the strength of our party in Stone Town. ”

Lao Hou thought for a while, and said to Minister Pan: "To protect the leading comrades through Stone Town smoothly, I thought about only two options. One is to use the signboard of Yokota Co., Ltd. so that this leader also has a cover identity like me, impersonating a member of Yokota Co., Ltd. through Stone Town. This identity is still very useful, but it needs your help. ”

Minister Pan frowned and shook his head and said, "I'm afraid this won't work, it has taken a lot of effort to arrange you into Yokota Co., Ltd. organizationally." I am afraid that it will be difficult to arrange another person to become a member of Yokota Co., Ltd. ”
