Junior Desk Officer vs KGB: The Story of Moscow’s Quietest Spy / 1

In the early seventies, junior desk officer Lyudmila Krylova worked quietly in Moscow. Quiet, inconspicuous, without a family. But it was she who became the first link in the deepest network of agents that the US had built in the USSR through diplomats, hiding places, couriers, and researchers.

The KGB kept her under surveillance for months until they got at the whole chain and conducted one of the most extensive operations of the Cold War. This investigation shows how spies met in cafés, hid documents in libraries, passed packages through ordinary workers — and how counterintelligence gathered evidence step by step to strike all at once.

Part I: The Discovery

The Ministry on Kalininsky Prospekt

In the winter of 1971, Moscow was freezing cold, but the city lived a familiar life, behind which lay work that was not spoken of aloud. In a building on Kalininsky Prospekt, home to the USSR Ministry of Foreign Trade, every morning began the same way: checkpoint, stairs, linoleum corridors, offices with heavy doors, and the smell of paper.

Hundreds of people worked here, and each of them had access to documents of varying degrees of importance. But it was here, amidst the files of trade agreements and supply contracts, that the case that would later be code-named “Winter” began.

For the whole month of January, in one of the departments involved in coordinating the supply of industrial equipment, worked junior desk clerk Lyudmila Vasilyevna Krylova. She was twenty-seven years old. She had graduated from a foreign language institute, spoke English and French, and she had been hired by the Ministry three years earlier.

Krylova lived alone in a one-room flat on Begovaya Street, unmarried, leading a quiet, measured life. Colleagues described her as a quiet, efficient employee who was never late, never complained about her workload, and rarely stayed late after work.

Her duties included translating documents, preparing memos for management, and correspondence with foreign partners. She had limited access to classified material, but she regularly worked with proprietary documents containing data on planned deliveries, prices, and contract terms.

The First Alert

At the end of January 1971, the First Chief Directorate of the KGB received information from external agents. A source working in one of the Western capitals passed on information that American intelligence services had intensified their work on collecting economic information in Moscow. It was mentioned that the object of interest was the ministries related to foreign trade and industry.

There were no specific names in the report, but there were indications: young employees with access to documents, knowledge of languages, no family, regular contact with foreigners.

This information was passed on to the counterintelligence unit that protects state institutions. The inspection began quietly. The operatives drew up a list of ministry employees who fit the description. There were about fifteen such people. For each of them, they asked for references, biographies, characteristics, social circle, trips abroad, financial status.

Krylova was on the list, but nothing suspicious was found in her file. The only thing that made her stand out was a mention in one of the ministry’s security reports that in December last year she had attended two receptions at the French embassy, where she was invited as an interpreter. This was within the scope of her official duties, and no offenses were recorded.

However, the operatives decided to put her under surveillance.

Surveillance Begins

In February, the work began. Krylova was taken under control in the morning when she left the house and was followed into the evening. Her route was predictable: metro, work, lunch break in the Ministry canteen. In the evening, the metro again and home. On weekends, she went to the shops, occasionally to the cinema. Sometimes she met a friend from the institute. Nothing unusual.

The telephone conversations were monitored, but there was nothing but mundane topics. Correspondence was checked, but she received few letters, mostly from her parents who lived in Kaluga.

Three weeks had passed and the operatives were ready to lift the surveillance when an incident occurred that changed the course of the case.

The First Meeting

On a Tuesday in mid-February, Krylova didn’t go home after work, but headed towards the center. She got off at Arbatskaya metro station and walked on foot through the streets of old Arbat. The weather was cold, the snow was falling in large flakes, and there were few people on the streets.

Krylova walked confidently, did not look around, did not stop at shop windows. She reached a small café on Kropotkinskaya Street, went inside, and sat down at a table by the window.

The operatives who were conducting surveillance recorded this moment. One of them entered the café a few minutes later and took a seat at a nearby table. Krylova ordered tea and sat looking out the window.

Ten minutes later, a man entered the café. He was about forty years old, wearing a dark coat and a hat. He looked around, walked over to Krylova’s table, and sat across from her. They said hello, but the conversation was short and quiet. The operative couldn’t hear the words, but he saw Krylova take an envelope out of her bag and hand it to the man.

He took the envelope without opening it and put it in the inside pocket of his coat. They sat for a few more minutes, then the man stood up, nodded, and left the café. Krylova finished her tea, waited about five minutes, and left too.

The man was observed in parallel. He left the café, walked two blocks, got into a car with diplomatic plates, and drove off. The car was identified. It belonged to the U.S. Embassy.

This was the first concrete evidence of Krylova’s possible connection to foreign intelligence.

Identifying the Contact

The operatives immediately reported it to their superiors, and the case took on a new status. Now they needed to identify the man, find out what was in the envelope, and understand how long these contacts had been going on.

A check on the U.S. diplomatic corps showed that the embassy employed several employees matching the description. One of them was Robert Harris, who was listed as an attaché for trade matters. He was forty-two years old. He had arrived in Moscow a year and a half ago. He was officially in charge of coordinating trade relations between the USSR and the United States.

According to counterintelligence, Harris had ties to the intelligence community, but there was no direct evidence of him working for intelligence. He behaved discreetly, met with Soviet citizens only in an official capacity, and avoided suspicious contacts.

Now there was a clue.

Checking Her Activities

The next step was to check Krylova’s official activities. The operatives contacted the ministry’s leadership and requested information about the documents she’d been working with in recent months.

It turned out that in January, Krylova was preparing briefs on negotiations with the American side on the purchase of industrial equipment. These briefs contained data on the planned volumes of supplies, prices, timing, as well as the Soviet side’s position in the negotiations. The documents were not secret, but were of interest to those who wanted to know the USSR’s economic plans.

If Krylova gave copies of these documents to Harris, that would be a serious offense.

Intensified Surveillance

The operational work continued. Krylova was placed under twenty-four-hour surveillance. Her phone was tapped, her mail was monitored, her movements were recorded. Her flat was searched covertly while she was at work.

They found a few things that were of interest: a notebook with notes in English that looked like outlines of work documents, and a small amount of cash, about three hundred rubles, hidden in a book. The amount was not very large, but it was unusual for someone on her salary. They also found photographs, one of which showed Krylova with Harris at some kind of reception. This confirmed their acquaintance.

In early March, operatives determined that this wasn’t the first time Krylova and Harris had met. An analysis of her movements over the last six months showed that she had deviated from her usual route at least four times and headed for the city center. Each time was on weekdays, in evening hours, and each time she went to places where she could meet discreetly: cafés, parks, museums.

There was no definitive proof that she was meeting Harris specifically, but the timing and locations didn’t seem coincidental. Checks showed that Harris was also absent from the embassy in the afternoon on the same days, which was recorded by the diplomatic surveillance system.

Planning the Operation

The task force was tasked with gathering enough evidence to either apprehend Krylova or launch an undercover operation against her. The brass was leaning towards the second option, because Krylova could be used to gain access to American intelligence methods, understand what kind of information they were interested in, and possibly identify other agents within the government.

But this required careful action so as not to spook either Krylova or Harris.

In mid-March, an operation was organized to intercept the next meeting. The operatives knew that Krylova usually met with Harris every three to four weeks. The last meeting was in the middle of February, so the next one would have to be in early March. Surveillance was stepped up. Krylova was followed by several groups that rotated so that she would not notice the surveillance. Harris was also being monitored, but more discreetly, as any suspicion could lead to a diplomatic scandal.

The Park Meeting

The meeting took place on Tuesday, March 10. Krylova was not going home after work, but in the direction of Gorky Park. She got out of the metro and headed towards the embankment of the Moskva River. The weather was overcast, the wind from the river was cold, and there was almost no one on the embankment.

Krylova walked slowly, stopping from time to time and looking at the water. The operatives kept their distance, using cover and changing positions.

Twenty minutes later, Harris appeared. He was coming from the opposite direction, wearing a long coat and cap. They met at one of the benches and sat down side by side.

This time, the operatives had set up equipment in advance to record the conversation. One of the officers, dressed in work clothes, was nearby, pretending to be repairing a fence. He had a directional microphone that could record conversations up to fifty meters away. The recording quality wasn’t ideal due to wind and river noise, but they were able to get the basic phrases.

Harris spoke Russian with a noticeable accent, but fluent enough. He asked Krylova about her work, about what documents had passed through her hands recently. She answered briefly, naming the subjects of the negotiations, mentioning the names of Soviet officials who were involved in the discussions. Harris asked for details — what figures appeared in the documents, what positions the Soviet side was defending, whether there were disagreements within the delegation.

Krylova answered his questions without showing excitement. Then she took folded sheets of paper out of her bag and handed them to Harris. He looked them over quickly, nodded, and tucked them away in an inside pocket. After that, he handed her a small envelope. Krylova took it without opening it and put it in her bag.

The conversation continued for a few more minutes. Then they stood up and went in different directions.

Analyzing the Evidence

The operatives let them leave without making any attempt to apprehend them. The goal was to gather as much information as possible, not to scare off the targets of surveillance.

A recording of the conversation was immediately brought back to headquarters and decrypted. Analysis revealed that Krylova gave Harris copies of official documents relating to negotiations for the purchase of process equipment for the oil refining industry. These documents contained information about the USSR’s needs, financial capabilities, and on what terms the Soviets were willing to contract.

For American intelligence, such information was valuable, as it allowed them to understand the economic strategy of the USSR and to use this information in political and trade negotiations.

The envelope that Harris handed to Krylova was of particular interest. The operatives speculated that it might contain money and instructions.

The Second Search

To find out, they decided to conduct a second warrantless search of Krylova’s flat. The search was organized the next day when she was at work. A group of operatives entered the flat using lock picks and conducted a thorough inspection.

An envelope was found in the wardrobe in the pocket of one of her coats. Inside was money: five hundred rubles and one hundred US dollars. This confirmed that Krylova was receiving payment for passing on information.

In addition to the money, several other items of operational interest were found in the flat. In one of the books on the shelf was a piece of paper with notes that looked like a list of questions Harris had asked in previous meetings. Among the questions were: which ministries were involved in preparing trade agreements? Who makes the final decisions? What documents go through the department where Krylova works? Is there access to classified material?

These records showed that Harris was purposefully gathering information to understand the structure of the department and what Krylova’s options were for obtaining information.

A notebook was also found in which Krylova kept something like a diary of meetings. There were dates, places, short notes. For example, an entry from February: “Café Kropotkinskaya, documents on negotiations.” An entry from January: “Pushkin Museum, contract reference.”

These records confirmed that the meetings took place regularly and that Krylova handed over materials systematically. In total, the notebook recorded eight meetings between October last year and March this year.

Expanding the Investigation

The management of the task force decided to continue surveillance and not to take active measures for the time being. The aim was to establish whether Krylova had links with other agents, whether she was aware of the existence of other sources of information in the ministry, and what methods U.S. intelligence uses to recruit and manage agents.

In addition, it was important to understand who was behind Harris, what his role was in the intelligence structure, and whether he had other contacts in Moscow.

To that end, it was decided to set up surveillance not only on Krylova and Harris, but also on their entourage. The operatives checked all of Krylova’s acquaintances: colleagues at work, a friend from the institute, neighbors at home. No one suspicious among them. All of them led ordinary lives, had no connection with foreigners, and did not show any interest in Krylova’s work. This meant that Krylova was acting alone and wasn’t part of a wider network.

Checking Harris’s entourage proved more difficult. As a diplomat, he was entitled to immunity, and direct surveillance of him inside the embassy was impossible. However, the operatives recorded his movements around the city, his meetings with other people, his attendance at official functions.

Over a two-month period of surveillance, they determined that Harris met several times with Soviet citizens who had no connection to diplomatic work. These included an employee of a research institute, a university lecturer, and a man who worked in the archives. These meetings aroused suspicion, and additional checks began.

The Bigger Picture

At the end of March, it became clear that Harris was working with several sources at the same time and that Krylova was only one of them. This made the task more difficult, but it also opened up the possibility of a larger operation.

The KGB leadership decided not to limit themselves to Krylova’s case, but to launch a broad investigation into all of Harris’s contacts with Soviet citizens. For this purpose, a special group was created, which included operatives from various counterintelligence units.

However, the focus remained on Krylova. She remained the most accessible and most controlled target. She could be used to influence Harris, pass along misinformation to him, to lead him into mistakes. But to do that, they had to either recruit Krylova or take control of her and force her to work under the direction of counterintelligence. Both options required careful preparation and precise calculation.

Understanding Her Background

At the beginning of April, a series of measures were carried out to investigate Krylova’s background and psychological profile. The operatives met with people who knew her at different periods of her life: teachers from the institute, classmates, former colleagues from her first job.

They all spoke about her in much the same way: capable, diligent, reserved. She had few friends, and her personal life wasn’t going well. After graduating from the institute, she worked for several years as an interpreter in a trade representative office, and then moved to the ministry.

Her parents lived in Kaluga. Her father worked as an engineer at a factory, her mother was a teacher. The family was ordinary, with no compromising connections or political problems.

However, in the course of the investigation, one detail came to light that could explain Krylova’s motives.

The Turning Point

In 1968, when she was in her fourth year at the institute, she had an affair with a foreign student from France who was doing an internship in Moscow. The affair was short, a few months, but quite serious. They planned to get married. Krylova even filed documents for traveling abroad. But she was not granted permission, and the French student at the end of his internship was expelled from the country.

After that, Krylova became withdrawn, stopped socializing with her classmates, and completely immersed herself in her studies.

This episode could have been a turning point in her life and caused her to resent the system, making her vulnerable to recruitment. The operatives surmised that this experience could have been used by US intelligence to make contact with Krylova. It’s possible that Harris or one of his predecessors learned of this story and used it as leverage for recruitment.

However, the exact circumstances of her contact with the Americans remained unknown. It was either a matter of getting a confession from Krylova herself or finding documentary evidence.

The Decision

In mid-April, there was a meeting of the task force to discuss further actions. Two main options were proposed.

The first: detain Krylova, investigate her, get a confession, and use her testimony to get Harris expelled from the country. This option was simple and quick, but it had a major flaw. It didn’t identify Harris’s other agents and it didn’t allow for an undercover operation.

The second option: recruit Krylova and turn her into a double agent who would work under KGB control. It was a more difficult and risky path, but it opened up wide opportunities for counterintelligence work.

After much discussion, it was decided to try the second option. To realize it, it was necessary to carry out an operation to recruit Krylova, which should look natural and not arouse Harris’s suspicion.

The plan was to create a situation where Krylova would realize that her activities had been exposed and the only way to avoid punishment was to cooperate with counterintelligence. It was important not to frighten her to the point where she would try to escape or commit suicide.

The operation was scheduled for the end of April.

The Recruitment

The operatives chose the moment when Krylova was returning home from work. It was an ordinary weekday evening. There were a lot of people on the streets. Krylova got out of the metro at Begovaya station and headed towards her house. She was followed by two operatives, keeping their distance.

As she turned into a less crowded alley, one of the operatives quickened his pace and approached her. He called her by name and patronymic, showed her his ID, and asked her to come with him for an interview.

Krylova stopped, turned pale, but did not resist. She nodded silently and walked with him to a car that was waiting nearby.

She was brought to one of the KGB buildings on the outskirts of Moscow. It was a small office building where unofficial meetings and conversations were held. Krylova was taken to a room on the first floor, where an operative officer named Sokolov was waiting for her.

He was a middle-aged man, calm and polite. Krylova sat down on the chair, clasping her hands in her lap. Sokolov offered her tea, but she refused. He sat down opposite and started a conversation.

The Interrogation

Sokolov did not immediately accuse Krylova of espionage. He started from a distance, asked her about her work, how she got into the ministry, whether she liked the service. Krylova answered monosyllabically. Her voice was quiet and strained.

Then Sokolov moved on to more specific questions. He asked if she knew Robert Harris.

Krylova froze for a moment, then nodded.

Sokolov asked how long they had known each other. She replied that they met about a year ago at an embassy reception.

Sokolov asked if they had met after that. Krylova was silent, then quietly said that they had met several times.

Sokolov did not rush her. He gave her time to gather her thoughts, then put some photographs in front of her. On them were Krylova’s and Harris’s meetings: in the café on Kropotkinskaya, on the embankment at Gorky Park, in the museum.

Krylova looked at the photographs and lowered her head.

Sokolov said that counterintelligence was aware of her contacts with Harris, about the transfer of documents, about the money she was receiving. He said that this was a serious offense for which there were severe penalties.

Krylova was silent, her hands trembling.

The Confession

Then Sokolov changed his tone. He said that he understood how she could have been in this situation, that sometimes people make mistakes under the influence of circumstances. He asked how exactly Harris had come out to her, what he had promised, how he had persuaded her to cooperate.

Krylova was silent for a long time, then she started talking. Her voice was barely audible. The words came out with difficulty.

She said that she met Harris at a reception at the French Embassy last November. He approached her, struck up a conversation. They spoke in French. Harris was charming, attentive, interested in her work. A few days later, he called her at work, invited her to lunch. She accepted.

They met at a restaurant. The conversation was light, nothing serious. Harris talked about his work, life in America, asked about Moscow. Krylova felt free. It was the first time in a long time someone was interested in her.

The meetings continued. Harris was cautious, did not rush things. It wasn’t until the third or fourth meeting that he started asking questions about her work at the ministry. At first they were general questions, then more specific. He asked what documents passed through her hands, who she worked with, whether she had access to classified information.

Krylova was evasive at first, but Harris was persistent. He said that he needed this information for his work, that he was dealing with trade issues and needed to understand how the Soviet system works. He said it wasn’t espionage, just an exchange of information that helped both sides better understand each other.

Krylova gave in. She started talking about her work, about the documents she was dealing with. Harris listened intently and occasionally asked clarifying questions.

After a few weeks, he asked her to bring copies of some documents. Krylova refused at first, but Harris convinced her. He said it would help him in negotiations, that no one would know, that the information was safe. He also said he was willing to pay for her help.

Krylova hesitated, but finally agreed. She needed the money, and Harris’s offer didn’t seem so scary to her.

The Pattern

The first transfer of documents took place in December. Krylova made copies of several references relating to trade negotiations and gave them to Harris at a meeting at the museum. He gave her an envelope of money.

After that, the meetings became regular. Harris would call her, set up a time and place. Krylova would bring the paperwork, get the money. She knew she was doing something wrong, but she couldn’t stop. She needed the money, and Harris treated her well, and she felt important.

Sokolov listened attentively without interrupting. When Krylova finished, he asked if she knew of any other people Harris was seeing. She replied that she did not know.

Sokolov asked if Harris had given her any instructions in case her activities were discovered. She replied that he did not. They never discussed that possibility.

The Offer

Sokolov paused for a moment. Then he told Krylova that her situation was very serious. Espionage in favor of a foreign state was punishable by a long term of imprisonment, and escape was practically impossible.

However, he also said that there was one way that could mitigate her guilt and possibly allow her to avoid prison.

Krylova raised her head, looking him in the eye for the first time in the entire conversation.

Sokolov explained that if she agreed to cooperate with counterintelligence, to continue her meetings with Harris, but under KGB control, it would be taken into account when considering her case.

Krylova remained silent. She realized that she had no choice. Refusal meant imminent arrest, trial, camp. Cooperation gave at least a ghostly chance of freedom.

She asked exactly what would be required of her.

Sokolov said that she would have to continue to meet Harris as before, but the documents she gave him would be prepared by counterintelligence. These documents would contain partially true, partially distorted information to mislead American intelligence about Soviet plans. In addition, Krylova would have to report all contacts with Harris, all his questions and demands.

Krylova asked how long this would last. Sokolov replied that it depended on the progress of the operation. Perhaps a few months, possibly longer.

She asked what would happen to her afterwards. Sokolov didn’t give a definitive answer. He only said that if she cooperated honestly, it would be taken into account in deciding her fate.

Krylova realized there were no guarantees, but there was no other way.

She agreed.

---

What began as a routine check quietly turned into a pattern.

One meeting led to another, caution gave way to habit, and habit slowly became dependence.

At this stage, no one was yet rushing to make arrests. The case was only beginning to take shape.

To be continued.
