My spy diary

Chapter 199 Deciphering the Secret Message (asking for monthly ticket)

After coming out of the Secret Service, Secretary Liu stuck to Zhang Yi like a dog-skin plaster.

"Deputy Section Chief, Deputy Section Chief Wang is leaving soon. Do you want to rearrange your office?"

"What the hell, how long can we stay in Jinling?"

Zhang Yi shook his head speechlessly. Faced with Secretary Liu's deliberate flattery and courtesy, he had no reaction.

But Secretary Liu continued to flirt with her without knowing the situation:

"Deputy Section Chief, I think it's not too much to redecorate it. After all, a new section chief brings a new atmosphere. Just leave these things to me. Don't treat me as an outsider. I am your secretary, and we have a close relationship."

Zhang Yi looked at him deeply and sneered in his heart, "You've never eaten pork, but you've seen a pig run?"
In his understanding, secretaries can be roughly divided into three types. One type is the confidant type, with whom they can talk about anything, no matter official or private matters, including personal feelings and privacy, and they can be trusted with anything. The trust between them is even greater than that between their own relatives.

The second type is the basic trust type, which is limited to the official business scope. This person is more convenient and reliable to use at work.

The last type is the one that only deals with the relationship on the surface. They are like a couple without feelings for each other. They appear polite to each other, but in fact they have strong dissatisfaction and vigilance towards each other. They may be only one step away from separation and divorce.

Looking at Secretary Liu, Zhang Yi asked with interest:
"Secretary Liu, I heard that you are a top student at Fudan University. How come you are just a spy? The reputation of the Secret Service is not good."

"Of course, we should respond to the call and defend our country." Secretary Liu said without hesitation.

"I want to hear the truth." Zhang Yi looked at him with a smile without saying a word.

Secretary Liu was frightened by the look. He touched his nose awkwardly and said:

"I come from the countryside. My parents run a stall in the city. It's not easy for them to support me in school. I don't want them to be bullied anymore."

"It's not shameful to tell the truth. We can't just shout slogans." Zhang Yi said lightly.

"Also, in my opinion, decorating and cleaning the office is just one aspect of being a secretary. It belongs to the initial stage. What's more important is the support for work. What do you think, Secretary Liu?"

Secretary Liu just laughed dryly twice.

"The Telecommunications Department has seized a batch of telegrams about the Japanese army's bombing of Nanjing. Go and borrow them." Zhang Yi gave the order directly, then got in the car and left.

As for whether Secretary Liu can find where the door to the telecommunications department is, that is his own business.

To Zhang Yi's surprise, half an hour later, Secretary Liu actually got the captured code.

Zhang Yi sent him away and called Monkey Qian Xiaosan to discuss the matter together.

Generally speaking, intercepted enemy radio coded telegrams require cryptographers to decipher them, but it is almost impossible to decipher them with just one telegram.

Code breaking is a "desk job". The process of code breaking is to first copy the message, that is, copy down the enemy's telegram from the receiver, and make many copies. The more copies there are, the more similarities you will find, and the easier it will be to decipher.

This requires repeated comparison, analysis, thinking and calculation before it can be deciphered.

The telegram placed in front of Zhang Yi and others at this moment was not the usual Morse code, but a simplified version.

Because normal Morse code uses ten numbers from 0 to 9, but the telegram in front of you frequently uses only seven numbers from 1 to 7. No matter how you arrange and combine them, or how you translate them, it will still be a mess of gibberish and will not express the meaning.

The only thing they have in common is that the telegram is signed "WM" at the end.

This could be the agent's initials or a code name.

It could be Perfect, Wu Ma, Wang Mang, Appearance, Wu Mao, Wu Ming, Wang Min, etc.
Monkey said: "Chief, according to the intelligence department's previous investigation and the clues provided by witnesses, every time before the enemy plane bombed, a person holding a red umbrella would appear at the scene to pass on the location to the enemy in the sky...

At night, they would use flares to transmit information. These spies are ordinary bosses during the day, roaming the streets to gather intelligence. It is impossible to prevent people from going out, right? "

"We couldn't grasp the time and location of enemy bombings. Every time we received a tip-off and the plainclothes officers went to arrest people, the spies had already disappeared."

"Yes, this person is extremely cautious. Each time he sends a message, the time is very short, and he changes his position frequently. It is impossible to locate him at all."

Listening to the two people's conversation, Zhang Yi looked at the illogical groups of numbers in front of him, wanting to crack them but having no idea where to start.

He kept muttering "wm" in his mouth, thinking, charming, black plum, and suddenly a line of lyrics came out of his mind.

He thought of a movie he had seen in his previous life, which seemed to be called "East Wind and Rain". Both sides used music played on the piano to transmit information.

Later, Zhang Yi searched for relevant documents. It has never been recorded in the domestic intelligence history, but this method does exist. Germany once sent a beautiful pianist spy to infiltrate France. She used the opportunity of a consolation performance to extract intelligence from the Allied forces and used different arrangements while playing to convey the intelligence.

So does this "WM" also use a similar method to transmit information?

What if the number combination from 1 to 7 is not an abbreviation of the so-called Morse code, but the seven basic notes in music: do, re, mi, fa, sol, la, si?
Thinking of this, Zhang Yi immediately treated the seized telegram in front of him as a piece of music and hummed it according to his feeling.

Monkey and Qian Xiaosan stared at Zhang Yi with suspicion, wondering what had happened to the section chief. He was frowning just now, but now he suddenly started humming.

Especially Qian Xiaosan, as he listened, his expression suddenly became strange. He coughed lightly and said to Monkey: "You mean the Section Chief. Right? Hmm."

"what?"

"You've heard of the story about the widower being ill, right?"

"What and what? Are you saying that the section chief misses a woman?"

"Is not it?"

Qian Xiaosan looked disdainful:
"I thought you were very clever, but you can't even understand such a simple hint?

What is the next sentence of "I am ill"? I am lustful!

What was the section chief humming just now? Hey, this is what the girls in the brothel sing when they are having fun with the guests. Last year, there was a movie called "The Strange Case of Guta" that used it as the theme song. What is the name of this song? Let me think... Oh, right, it's called "Autumn Water Beauty."

"Looking through the autumn water, I can't see the beautiful figure of my beloved"

Seeing the two people whispering, Zhang Yi immediately asked: "What are you talking about?"

The monkey quickly explained.

Zhang Yi slapped the table, smiled broadly, looked at Qian Xiaosan's wretched face, looked at him admiringly, and asked:
"Do prostitutes and their clients in brothels really sing this song?"

"Hehe, it's like this." Qian Xiaosan smiled obscenely, hesitated for a long time, and waved his hands repeatedly:

"I heard it from others, but I haven't been there."

Zhang Yi curled his lips, and his admiration for him ended there.

But now that we know the name of this song is "Autumn Water Beauty", everything becomes much simpler.

Although the best results can be achieved by leaving professional matters to professionals, the premise is that simple problems should not be complicated.

The numbers 1 to 7 that appeared in the telegram did not need to be arranged in any combination. The spy only needed to transmit the music score via telegram, and the other party could obtain intelligence based on the lyrics.

This simplified telegraph code does not need to be deciphered at all. You can just write it down and know the content based on the transliteration.

However, the telecommunications department complicated it and used multiple methods to decipher it, which led them astray and naturally gained nothing.

Zhang Yi arranged the telegrams one by one and found that the number on each piece represented a chapter of music. Judging from the time of each chapter, each chapter represented a bombing operation.

And this so-called WM is black plum.

It should be the agent's code name.

He took out the latest telegram, which showed the time was 10 o'clock in the evening and the location was Dahua Spinning Mill. This place was nominally a spinning mill, but in fact it was a place for storing weapons and medicines.

Japanese fighter planes wanted to bomb this place at night, but in the extremely low visibility conditions, they could only guide the attack by firing flares through insiders on the ground.

Now that we know the Japanese bombing targets, time and location, everything will be easy.

Zhang Yi picked up the phone and said, "Chief He, I have something important to report."

At the same time, in an office not far from Zhang Yi's office.

Secretary Liu walked in quickly. Before entering, he looked back and around, then went in, closed the door, and locked it with skillful and brisk movements. At this moment, there was no longer any shyness or childishness on his face, but instead a bit of sophistication, maturity, and awe.

Then, he sat at his desk, opened the drawer, took out a pair of headphones and put them on. After a simple adjustment, he could hear the voice of Zhang Yi making a phone call to report.

Secretary Liu listened and took notes on paper.

The speaker was He Zhiyuan: "Deputy Section Chief Zhang, you said you cracked the Japanese army's secret message about bombing Nanjing? Are you sure?
At ten o'clock tonight, will they take action against the Dahua Cotton Mill? Secretary Mao is investigating this matter, so it's not good for our Operations Department to get directly involved, right?"

"Chief He, we can cooperate with the Air Force, set up an ambush in advance, and fight an annihilation war." This was Zhang Yi's voice, but before he finished speaking, he was interrupted by He Zhiyuan:
"First, report this matter to the Intelligence Department, Telecommunications Department and Secretary Mao. Compared to this Wu Mei, the mole lurking within the Guo Party is the most terrifying."

"Although it is common to say that the enemy has me and I have him, this kind of thing is common during war, but this mole is too harmful, and even dares to plot against the chairman.
I have thought of many ways to investigate, but none of them worked. Haha, this small animal, which is not very fast, is not only good at digging holes, but also good at hiding and has strong destructive ability. It must not be underestimated. "

"Okay, come to my office and we'll report to Boss Dai later."

The call was hung up at this point. Secretary Liu put down his headphones, his eyes shining. He had to pass on this important information.
