After finishing his meeting with Ryosuke Hase, Zuo Shige returned to the hotel and took the Blue Steel Express back to Jinling alone early the next morning.
According to his analysis, there were three channels for the leak of the cables, one was He Yijun, the other was the bureau headquarters, and the third was higher-level military and political officials.
Based on past experience, it is unlikely that the leaker is He Yijun. If she were a Japanese spy, many missions would not be successful.
For example, the destruction of the bacterial base of the Kwantung Army's water supply and epidemic prevention unit, and the 226 incident were enough to show the reliability of the other party.
The telecommunications personnel at the bureau's headquarters are also not spies. They have gone through the strictest screening, and their family relationships are checked through three generations when they join.
More importantly, the telegrams he sent previously have never been leaked, so it can be judged that the problem does not lie with the bureau headquarters.
Then there is only one possibility,
There are insiders at the top of the national government, or the relevant agencies to which intelligence is delivered.
This is easy to understand. Obtaining the information is only the beginning. There is still a series of work to be done, such as research, analysis, and recording.
For example, there are many people involved in the departments directly under the Military Commission, the bald attendant's room, and the staff department, and they are a mixed bag.
Wanting to find out the Japanese spies, Zuo Zhong felt that he had to go back to Jinling to take charge of the investigation work, because this matter could not be delayed any longer.
Seeing that the deadline of August 9th for the Japanese Navy Command to evacuate overseas Chinese is getting closer and closer, it is urgent to solve internal problems.
Fortunately, the distance between Shanghai and Jinling is not too far. Wu Chunyang and others have also practiced at this time, so he can come back without worries.
"Woo~"
Zuo Zhong thought like this all the way until he was reminded by the sound of the whistle. He looked up and saw that Jinling Railway Station had appeared not far away.
When the train stopped, he put on his hat and carried his suitcase and quickly left the carriage. After leaving the station, he stopped the rickshaw and reported an address.
This address has nothing to do with the Secret Service or the Bureau of Investigation and Statistics. It is a transit point for him to confuse the trackers.
If an enemy follows him, he will be easily exposed whether he is counter-tracking or going to military and political agencies, so transit is the best option.
This is not a false accusation. You must be cautious when dealing with Japanese spies. Those who are careless will die.
Half an hour later, the rickshaw stopped at the entrance of an ordinary small courtyard. Zuo Zhong got out of the car, handed over the fare, opened the door and walked in.
This is the outhouse of a smuggler who was shot last time. It has a private house and few neighbors nearby, making it very suitable for hiding.
After watching for a long time at the specially designed hidden observation port, Zuo Zhong made sure that there was no one behind him, and then he came to a room and moved the wardrobe.
A secret passage suddenly appeared. He took out his clothes from the house and put on them. He made some adjustments to his facial disguise and went straight into the secret passage.
When he appeared again, he was in the back room of a shop. A middle-aged man sat quietly in the room and seemed to not see anything.
"Be careful. If there is any problem, blow up the secret passage. As for you, you know what to do."
"I know, Deputy Director."
Zuo Zhong gave instructions before walking out of the house. The middle-aged man's answer was resolute. If you do this, your life will no longer be yours.
As for surrender, he never thought about it. The secret service's family rules for traitors are very simple. If one person surrenders to the enemy, the whole family will suffer, and no one can be exempted.
The former Tokyo station director was a big figure, and he was also a student at Huangpu. After it was confirmed that he had rebelled, his family disappeared overnight.
Later, I heard that several floating bodies appeared on the riverside. People from the Jinling Police Department did not check them, so they found a place to burn them clean.
If you don’t want your wife and children to become a pile of ashes in the wilderness, dying for your country is the only option.
After receiving a satisfactory reply, Zuo Zhong nodded and left quickly from the store lobby, walking quickly towards the Bureau of Investigation and Statistics building.
He kept stopping, turning around, crossing the road, and counter-tracking. The journey that was supposed to take dozens of minutes ended up taking two hours.
With his worries completely eliminated, Zuo Zhong approached the guard at the door, took out his ID, shook it, lowered his head and quickly entered the compound.
Seeing such perfunctory behavior, a young guard wanted to intercept him, but was immediately pinned down by several pale-faced veterans.
I don't want my life,
Even the smiling tiger dares to provoke him.
Although the other party had disguised himself, they had been stationed here for several years, so they naturally recognized that the person was the Deputy Director Zuo of the Secret Service.
Working in the Bureau of Investigation and Statistics, you can offend anything, but you can't offend this person, otherwise the person might be gone.
Zuo Zhong didn't know what the guard was thinking. He took a familiar route to the top floor and knocked on the office door of Lao Dai's secretary Li Wei.
People are most afraid of getting carried away. Normally, with his current status, it would not be a problem to get around Li Wei, but if he did so, he would offend others.
Don't underestimate the little people. Such people often fail to succeed but fail more than they do. There's nothing wrong with taking a few extra steps to build a good relationship.
Sure enough, when he saw Zuo Zhong meeting Lao Dai in the formal procedure, Li Wei was so happy that he couldn't help but ran out after saying a few words.
After a while, this guy trotted back and brought Dai Chunfeng's order, and then led Zuo Zhong to the door of the director's office.
Raising his hand to knock on the door and opening it gently, Li Wei turned around and left without waiting for a reply. He was really a smart man and acted in a measured manner.
Zuo Zhong must have important work to report when he comes here. It may be related to the war. The more you know about similar things, the more dangerous it becomes.
Curiosity can not only kill the cat,
It can also kill people.
Inside the room, Dai Chunfeng was reviewing documents with the gold pen that Zuo Zhong had given him a few years ago. When he heard the sound, he looked up and saw Zuo Zhong with a smile on his face.
"Here comes the caution. Sit down quickly. Is there something wrong in Shanghai? Don't worry. Monitoring the Caobang is a long-term job.
If you have any difficulties, you can directly tell the chairman and me. As long as it is conducive to the task, I will support you even if it is a rip-off. "
"Students thank the teacher."
Zuo Zhong automatically filtered these words, sat half-assed on the stool, considered it for a while, and said it under Lao Dai's doubtful eyes.
"The student has an important situation to report to you when he comes back this time. Before that, I would like to ask who has seen the Shanghai intelligence."
"Who has read the Shanghai intelligence?"
Dai Chunfeng frowned and repeated. He naturally knew what his disciple meant. Could it be that he was afraid that someone would leak the secret? This was impossible.
After receiving Zuo Zhong's intelligence yesterday, the telecommunications room was immediately sealed. Apart from him, only the Chairman and the military personnel knew about it.
By the way, there is also a cryptographic interpretation office. The chairman of the committee asked him to hand over the information to the other party so that he could decipher Japanese secret messages based on the telegraph signals.
But these people and institutions are either the head of state, the backbone of the party-state, or top-secret institutions, and there should be no problems.
At the same time, he also knew that Zuo Zhong must have a reason for asking, so he recounted what happened yesterday from beginning to end without hesitation.
Bald.
Confidential Room of the Military Commission.
Institutions above the military level.
Cryptographical Inspection Institute.
Zuo Zhong frowned after hearing this. The first thing he excluded was bald heads. No matter which angle he considered, the other party had no reason to do this.
What about the Confidential Room of the Military Commission? All the Party's military documents are uploaded and distributed from here. It would be troublesome if there were spies here.
But think about it from another perspective, if there are Japanese spies here, they will not just pass on a piece of information, but will definitely leave clues.
It is impossible for the Secret Service not to notice this. Zuo Zhong has this confidence. From this point of view, it can be judged that the suspicion of the members of the confidential room is not high.
The rest are agencies above the military level and cryptography inspection and interpretation institutes. One is crowded and the other is a highly confidential technical unit.
At first glance, the probability of a spy appearing in the former one is higher, but intelligence warfare cannot be based on common sense, and preconceptions are the most taboo.
And what level would the officer who had access to the strategic intelligence of the Japanese navy in Shanghai be? At least he would be a brigade commander or above.
At present, the Nationalist Government has a total of 191 army infantry and cavalry divisions and 52 brigades. How long will it take to find out so many officers, big and small?
There are only a few people in the Crypto-Interpretation Office. There are about one or two hundred people. They can be screened quickly. If they are not found, it will not be too late to check the military.
besides,
There is another reason to check this place first.
From the time the intelligence was sent to the time it was leaked, it didn't even take 24 hours. The Japanese spies could only report to the Naval Command in Tokyo through the radio.
The Cipher Interpretation Institute is an institution that specializes in deciphering telegrams. Its work is inseparable from the radio station, and being able to receive and send telegrams is the most basic requirement.
In short, based on the existing clues, the Cryptographic Inspection and Translation Office of the Department of Electrical Affairs of the Ministry of Transport is a key target and needs to be investigated as a priority and as soon as possible.
Of course, this does not mean giving up the investigation in other directions. Things are just priorities, and the military side is just taking a step back.
After roughly determining the direction of the investigation, Zuo Shige truthfully stated Hase Ryosuke's feedback, as well as his previous speculations.
"What, the information was leaked."
Dai Chunfeng, who was resting on the back of his chair, suddenly sat upright. How could this be possible? Who would dare to leak such sensitive information.
Once found out, it would be a crime that would lead to beheading. He didn't think any high-ranking official would surrender to the enemy without enjoying his wealth.
After all, he had grasped the overall situation of the Secret Service and the Bureau of Investigation and Statistics for a long time. After being panicked, Lao Dai calmed down and gave decisive instructions.
"Shen Zhi, I will go to the rest house immediately to report the matter to the chairman of the committee. Don't move at the translation office first, so as not to alert Hase Ryosuke and expose him.
If there is really a spy, he must be observing our reaction. No movement is worse than silence. All actions must be carried out covertly. "
"Yes, the teacher is wise, and the students think so too. In addition, it is best to find one or two reliable people from the translation office as internal agents."
Zuo Zhong bowed and replied respectfully, feeling relieved in his heart. As expected of Lao Dai, he immediately grasped the key point. It was true that he couldn't do anything without permission.
First, it is easy to alert Japanese spies.
Second, the cryptography verification station is very important.
At this critical moment when the Sino-Japanese war is in full swing, the deciphering of messages is related to the outcome of the war, and the inspection and interpretation office must not be messed up.
The safest method now is to cooperate with internal departments to find suspicious persons, screen them one by one secretly, and try to keep a low profile.
"Very good, you can take care of this matter."
Dai Chunfeng walked out quickly and ordered that as a superior, it is best to leave professional matters to professionals.
The Japanese bayonets were almost reaching the chest of the Nationalist government. Chaosing command was tantamount to aiding the evil, and he understood this truth.
Looking at Lao Dai Fengfenghuohuo's back, Zuo Zhong picked up the phone and notified Gu Qi, Shen Dongxin and Tongsuo who were left behind to come and join him.
Since ancient times, there have not been many soldiers. To deal with a Japanese spy, there is no need to transfer people from Shanghai back to Jinling City. These three people are enough.
