The airfield lay dark, the wind carrying the smell of aviation fuel. The year was 1943, and the moon was up—an agent’s moon, they called it, because on such nights only agents were sent out, and those who did not belong to their circle had no need to know what that phrase meant. The aircraft was a black Lysander, low and stout, sitting on the grass with the idle rumble of its engines. The pilot sat in the cockpit, where the paint had gone matte from wear.

He was very young. That night, everyone was very young. Two women stood at the edge of the grass. One was the agent.

The other was Vera Atkins. Vera Atkins was not tall. She wore an ordinary coat, because there was no uniform for the work she did. Her hair was pinned up neatly.

Her leather gloves were worn thin at the fingertips. She carried no clipboard. She never needed one. She remembered that the young woman beside her was twenty-three years old, trained in wireless transmission, in silent killing, and in dropping by parachute onto a French field at night without breaking an ankle.

She wore a French coat, French shoes, a French wristwatch. Every stitch had been checked. Every label had been removed and replaced. Her forged papers lay folded in her bag, beside a lipstick bought in Lyon in 1939, kept precisely for this moment.

Vera Atkins stepped forward and adjusted the collar of the young agent’s coat. She smoothed it with her thumb and said, in a quiet voice, “Empty your pockets. ”

The agent complied. They all complied.

They had been trained that way. And yet something always remained. There was always something small that England had unknowingly slipped into the seams of some other life, and it was Vera Atkins’s job to find it before the Germans did. Tonight it was a bus ticket.

A London bus ticket four days old, printed with the route number and the fare, and at the very bottom, in small letters, the instruction to keep it until the journey’s end. Vera Atkins took it between two fingers. She made no comment. She did not scold.

She put it in her own pocket and held it there, tight, until she reached home. “Fountain pen,” she said. “Yes. ”

“Comb.

”

“Yes. ”

“The photograph in your wallet. Show me. ”

The agent showed her a picture of a young man in French military uniform.

It was aged exactly as a photograph ages after four years in a wallet, because it had been deliberately aged in a London workshop by a man whose entire wartime job was to make photographs look old. “Good,” Vera Atkins said. She squeezed the agent’s hand. She did not embrace her.

This farewell moment was not for embracing. The embrace had happened in the flat on Baker Street two hours earlier, where they had drunk tea and where the agent had left a letter for her mother—sealed, undated, to be posted only in the event of something going wrong. The agent climbed the short ladder into the aircraft. The engines roared.

The grass bent in the wash. Vera Atkins stood and watched the wings tilt over the trees, watched the tail light fade, and waited until silence returned to the field. She stayed longer than the others. She always did.

She had done this more than four hundred times. One hundred and eighteen of them never came back. To understand why she went looking for them, and how far she was willing to go, you had to understand what she was in charge of, what it meant, and how few people in the British war effort were prepared to do it the way she did. The organization was called the Special Operations Executive.

It was not part of the army. It was not part of the ordinary intelligence services. Winston Churchill had ordered its creation in 1940 and told its founders to set Europe ablaze. That was the phrase—set Europe ablaze.

It sounded better than the work it described. The work was this: take ordinary young men and women, most under thirty, with no military background. Train them to blow up factories and railways. Train them to operate wireless sets under the pressure of survival.

Teach them the techniques of killing. Give them false identities so perfect that their own mothers would not recognize them from the papers, then fly them into occupied France one by one, in the middle of the night, to work with the Resistance. Some dropped by parachute. Others landed in Lysanders, on fields marked out by three people with electric torches.

Once on the ground, they were entirely alone. The whole point of their existence was that they would operate independently. A wireless operator in Buckinghamshire sent messages in Morse code; a girl in the country house typed them up; they went to Baker Street, where someone read them and decided what to do. Within that whole apparatus, one section dispatched agents to France.

It was called F Section. The F stood for France, because someone standing in a London corridor had decided it was as good a letter as any. F Section was run by a man named Maurice Buckmaster. He was decent and hardworking and led the section for most of the war.

But the person the agents knew, the one who saw them off, who wrote to their families, who sat late at night reading their signals, was not Buckmaster. It was his intelligence officer. His intelligence officer was Vera Atkins. She had not been born Vera Atkins.

She was born Vera May Rosenberg, into a Jewish family in Romania. She had come to England before the war and taken her mother’s surname. She spoke French and German as fluently as if she had learned them at the dining table as a child. She was not even a British citizen at first.

She could not become one until 1944, and she had to fight even for that. And this was the woman who effectively ran the human side of F Section. She decided which recruits went and which did not. She briefed them on the weather in Paris, the price of Metro tickets, which cafés on the Left Bank had been searched recently and which had not.

She read every wireless message. She noticed when a message did not sound like the person who was supposed to have sent it. And she was the one who went to the airfields. She did not have to go.

Nowhere in her job description did it say she had to stand on the grass at Tempsford or Tangmere. Buckmaster went sometimes, but not always. Some officers never went at all. They said, honestly, that it was too painful and served no operational purpose.

Vera Atkins did not think that. She believed that the last person an agent saw before the aircraft took off should be someone who knew their real name. So she went, every time. She drove to the airfield and stood on the grass and said the same words.

Empty your pockets. Show me your papers. Show me your photograph. Good.

She straightened collars, smoothed scarves, and pretended not to notice hands beginning to shake. She looked at faces, most of which she would never see again. She kept a diary. For every agent, a photograph, some notes, the name they used in the field, and small human details in her own private code.

What they had drunk that afternoon. What they had said about their mother, their brother, a fiancé killed in Norway. Whether they had cried, whether they had laughed, whether they had smoked, and if so, what brand. No one had told her to keep it.

It was not approved. She kept it anyway. It fitted neatly in her desk drawer. Later, after the war, when the drawer was emptied, when Baker Street closed and the whole department quietly vanished into history, she took the book with her.

She never let anyone read it. In the end, it was with that book that she went to Germany. The beginning of 1945 came as a silence. Through the autumn of 1944, F Section had lost messages from one agent after another.

Some had gone quiet because they were arrested. Some because they were shot on their own doorsteps. Some because their networks had been broken in the great roundups of the previous year and nobody in London had noticed quickly enough. Vera Atkins had noticed, and said so, and been told that this was the nature of the work.

Then Paris fell. Then the transit camps opened one by one. Then the news of the extermination camps reached the office on Baker Street. The lists began to arrive.

Not lists of the returned. Lists of the missing. When the numbers finally settled and the survivors had gone home, Vera Atkins counted the agents sent to France, personally. She counted those who had not come back, and she reached the number one hundred and eighteen.

One hundred and eighteen men and women she had seen off from the grass runway in the dark, bought tea for that afternoon, taken bus tickets out of their pockets, straightened their collars: one hundred and eighteen faces in her book, one hundred and eighteen envelopes that should have been—or already had been—sent to families. The British government, on the whole, was not much interested in what had happened to them. There was no polite way to describe how quickly the Special Operations Executive was wound up. After the victory, Baker Street was closed.

Papers were either burned or filed away. Officers were released. The men who had run the country sections went back to ordinary professions. Nobody wanted to talk about the broken networks.

Nobody wanted to think about the ones the German intelligence had run for months, feeding false information to London, and London had believed every word of it. In short, Whitehall had no interest in sending anyone to Germany to find out exactly what had happened to one hundred and eighteen dead spies. Especially not Vera Atkins. On paper, Vera Atkins was the last person anyone would send.

She was a woman. Until very recently she had not even been a British citizen. She held no military rank. She was not a lawyer.

She was not a police officer. She was not part of the war crimes process being painfully assembled in the British zone of Germany. She went anyway. She pushed.

She wrote letters. She worked her contacts. Finally she joined the Women’s Auxiliary Air Force in an ordinary capacity, so she would have a uniform and a rank when she interrogated camp guards. Eventually she secured a place in the British zone’s war crimes investigation team.

She managed to get a part-time driver, a room in a requisitioned house, a typewriter, and the theoretical permission to speak to prisoners. She had no staff to speak of. She had no budget to speak of. She had her diary.

She had one hundred and eighteen names. She had a command of German better than most of the men sitting across from her, and she had a patience sufficient to destroy them. She eventually traced the fate of one hundred and seventeen of them. One remained unknown forever.

She refused to close that file. She kept it open until her death. But for each of those one hundred and seventeen, she recorded in her own hand what had happened, where it had happened, and on whose orders—in many cases finding witnesses willing to give sworn statements, and in many others finding the executioner himself. She began with the ones she knew best.

She began with the women. F Section had sent thirty-nine women into France in total. Thirteen of them had not come back. Vera Atkins knew every one of their names.

She had drunk tea with each of them in the Baker Street flat. She had put each of them on an aircraft from the grass field in the dark. She had been told that four of them had ended their lives in a place called Natzweiler. In the summer of 1945 she heard the name for the first time, in a report so brief it was almost an insult.

It said: four English women, Natzweiler camp, injections, crematorium. She read it once, set it down, and read it again. Then, for a moment, she went back to the airfield. It was a different airfield.

It was the summer of 1942. The aircraft was a bomber, a Whitley converted for parachute drops. Its belly hung low. It was flying to a field south of Paris, and it would come back the same night.

The moon was up. It always was. Standing on the grass beside Vera Atkins was a small, sturdy young woman with dark hair. Her name was Andrée Borrel.

She was French. She was twenty-two years old. She had already faced war. In 1940, when the Germans entered Paris, she had worked as a nurse in the streets.

She had helped build an escape line for airmen over the Pyrenees. When the line was shut down, she came to London and volunteered for this work. She was the first woman F Section ever sent into France by parachute. Vera Atkins understood, though she did not say it, that she had never done this before either.

She had sent men. She had never sent a woman by aircraft. There was no precedent for it. The parachuting instructors had reported that Andrée Borrel was one of the best pupils they had ever trained.

Andrée Borrel wore a French coat over her jumpsuit. Her hair was clipped back. A knife was strapped to her ankle. She carried false papers in the name of a French shopgirl.

Fifty thousand francs were sewn into her belt. Vera Atkins straightened the collar of her jumpsuit. She checked the stitches. She put a hand into the pockets and found one strange thing—an English lozenge, a cough sweet.

Andrée Borrel looked at it, shrugged, and laughed once in her characteristic way. Vera Atkins took it and put it in her own pocket. “Bonne chance,” she said. Andrée Borrel answered in French: “Au bientôt.

” It was a polite farewell. Literally, it meant, until we meet again. Andrée Borrel climbed into the aircraft. The engines roared.

The tail lights faded. Vera Atkins stood until the field was empty. By the summer of 1945, she knew that Andrée Borrel had survived eight months in France, helping to run one of the largest Resistance networks in the country. She knew that in the summer of 1943 she had been arrested with most of her circuit, held in Fresnes prison outside Paris, then transferred to a civilian prison in Karlsruhe.

She knew that on a day in July 1944, with three other women, she had been taken by train to a camp above a village in the Vosges mountains called Natzweiler. The camp was Natzweiler-Struthof, the only concentration camp on French soil. At various times it held Resistance fighters, Norwegians, Russians, Jews, homosexuals, criminals, and many people classified under the initials NN—Nacht und Nebel, “Night and Fog”—which meant they were to disappear without record and without word to their families. These four women were NN prisoners.

Vera Atkins went to that camp in the autumn of 1945, driving in borrowed British army clothing. The road up from the village was steep and lined with pines. Before she left London, she had been told at Baker Street that the Germans had evacuated the camp ahead of the American advance in the summer of 1944, that many prisoners had been taken east to worse places, but that the huts were still standing. She saw the huts.

She saw the small crematorium. She stood on the parade ground and looked down at the rooftops of the village. It was a beautiful place, in exactly the terrible way such places are beautiful. She made no comment.

She never commented on it, even in her letters. In her book she only wrote that she had been there. She began looking for people who had been at the camp in July 1944, when the four English women had come up the road. She found several—a former prisoner, a doctor, a camp interpreter, and a guard captured by the French.

She sat with each of them in small rooms and asked, in a voice she never raised, what they had seen. She learned that on the evening of 6 July 1944, the four women had been brought into the camp under guard. They had walked. They had come from a car at the gate.

They were kept together and, against the usual practice, not registered. They were taken to the crematorium building and locked in a room on the ground floor. They were given food, but they barely ate it. By then all four were still alive.

As far as it could be reconstructed, the four women were told they were to receive inoculations against typhus. What Vera Atkins learned, she wrote in her book. She wrote nothing beyond what was necessary. She always limited herself to what could be proven.

She learned that a camp doctor had gone into each cell in turn that night. She learned that the doctor carried a syringe. She learned that the substance in the syringe was carbolic acid, or phenol, injected into the heart; it was not a natural death, but properly administered, it was not a lingering one either. She learned that the four women were taken one by one into the room next to the cells where the crematorium was, and that the crematorium was used.

She learned that the procedure normally followed that night was not followed correctly in a single case. She learned that one of the four regained consciousness. She learned that the men present understood immediately what that meant. She added nothing more to the file than what the trial documents would later say.

That was her habit. She wrote in her book that one of the four regained consciousness before the end. She did not name her. No one could say with certainty which of them it was.

But she thought of Andrée Borrel, of that small, dark room at the airfield, of the shrug and the single laugh and the words “au bientôt,” and she closed the file. She opened another. It was a different night. It was the spring of 1944.

The moon was exactly as much as it needed to be. The aircraft was a Liberator. It would carry supplies as well as an agent. It would not land.

The agent standing on the grass this time was not tall. She had a small handbag, a smart coat, lipstick, and her dark hair was neat. She was, altogether, a strikingly attractive young woman. Her name was Violette Szabo.

She was twenty-three years old. She had an eighteen-month-old daughter with her mother in Brixham. Her husband had been a French officer, killed at El Alamein before he ever saw his daughter. Violette Szabo spoke French with a Parisian pull because her mother was French.

She had grown up in London. Before the war she had worked at the perfume counter at Bon Marché in Brixton, and she was very good at it. The last time an officer told her she should blend in with her circumstances, she looked at him dryly and said she had blended in at a perfume counter for four years, so she hoped she could manage again. She was on her second mission.

Three months earlier, on her first, she had gone to survey what remained of the Salesman circuit around Rouen. She reported that the circuit was almost entirely destroyed. Now she was back. This second mission was dropping her near Limoges.

The Normandy landings were days away. Her job was to help a colleague establish a new circuit in Corrèze to disrupt the movements of German forces in the north. Vera Atkins stood beside her on the grass. A Free French officer stood to one side.

A war correspondent present against the rules would later describe Violette Szabo in his notebook as pretty, cheerful, and intensely practical. Vera Atkins straightened the collar of Violette Szabo’s coat. She smoothed the shoulder. She put a hand into the pockets.

She found a photograph. An eighteen-month-old girl, sitting on a carpet, smiling at the camera. She did not take it. She looked at Violette Szabo.

Violette Szabo looked back. “I know,” Violette Szabo said. “Are you sure? ”

“I’m sure.

”

Vera Atkins put the photograph back in the pocket. She squeezed Violette Szabo’s hand. Violette Szabo climbed into the aircraft. The engines roared.

The tail lights faded. By the summer of 1945, Vera Atkins knew that Violette Szabo had landed safely near Limoges on 8 June 1944. She knew that on the morning of 10 June, as Violette Szabo drove in a car with a local Resistance leader, the car had run into an SS roadblock. She knew that Violette Szabo had held off the patrol with a Sten gun from behind a wall until her ammunition ran out.

She knew that Violette Szabo had been captured wounded, taken to the prison at Limoges, then to Paris, then to Fresnes, and finally to Ravensbrück. She knew that Ravensbrück was a women’s concentration camp fifty miles north of Berlin, that it had been evacuated in the winter of 1945, and that in its final month the SS had executed many women they did not want left alive. She knew that Violette Szabo had not come back. In the summer of 1945 she did not know how.

She began to search. The Red Army had liberated Ravensbrück. The camp lay in the Soviet zone. It was not easy for a British officer to enter.

Vera Atkins used every channel she had. She wrote to survivors. She read testimonies. She sat quietly with women who had returned from Ravensbrück and asked whether, in the winter months, they had seen three particular English women.

Two of those she was asking about were Denise Bloch and Lilian Rolfe. They, too, had not come back. Denise Bloch had been on the same aircraft as Violette Szabo on 8 June. Lilian Rolfe had been in Paris a long time, arrested in July, and taken east in the same sweep.

Vera Atkins was looking for all three together because they had been seen last together. Eventually she spoke to a Frenchwoman who had been at Ravensbrück the previous winter. The Frenchwoman knew Violette Szabo by her field name. She knew Denise Bloch and Lilian Rolfe.

The three women had been brought to the camp from another place and kept together. The Frenchwoman described, very carefully, the condition they were in by winter. Violette Szabo was very ill and weak and walked with a limp from her injuries, but her morale was intact. Denise Bloch could not move without help.

Lilian Rolfe, toward the end, was carried on a stretcher. One winter evening the three were ordered to report from their block to the camp office. The Frenchwoman saw them go. Violette Szabo walked as well as she could.

Denise Bloch was supported on both sides by the other two women. Lilian Rolfe was on a stretcher. The Frenchwoman never saw any of the three again. Vera Atkins wrote it all in her diary.

She added nothing. She did not need to. In the following months she tracked down personnel who had served at Ravensbrück and found several, one by one. Eventually she found a camp member who had been present in the small yard behind the camp office that night.

She also found documents. She found the orders. She read them. The three women were taken to a small yard behind the office.

They were told to kneel. They were shot one by one in the back of the neck. The camp doctor signed the death certificates. The bodies were taken to the crematorium.

Vera Atkins wrote the date in her diary as closely as she could determine it. The evening of 5 February 1945. She sat in the small room and thought of the spring airfield, of Violette Szabo climbing into the aircraft with her daughter’s photograph in her coat pocket. She closed the file.

She opened another, and again there was the airfield. It was the summer of 1943. The aircraft was a Lysander. The moon was up.

At one end of the field stood an old wooden hut where pilots signed in and out. Inside was a stove and a kettle. Vera Atkins stood on the grass outside the hut with an agent she had come to know very well, and she was worried about her. She had been worried about her for weeks.

The agent’s real name was Noor Inayat Khan. She was twenty-nine years old. Born in Moscow. Raised in Paris.

Her father was an Indian musician and a mystic of the Sufi tradition. Her mother was American. She had studied at the Sorbonne. She played the harp.

She wrote stories for children—a collection published in Paris before the war, and quite a good one. She was, by upbringing and belief, a pacifist. She spoke flawless French, was brave to the point of recklessness by her own admission, and in the summer of 1943 she was one of the only qualified wireless operators of the right age and background available to F Section. Her training reports had not been encouraging.

The instructors wrote that she was dreamy. They wrote that she did not always take security seriously. They wrote that in their opinion she should not be sent. The circuit in Paris she was going to desperately needed a wireless operator.

At that stage of the war, wireless operators were dying at a rate no one at Baker Street wanted to say aloud. The life expectancy of a wireless operator in Paris, from arrival to arrest, had begun to be measured in weeks. Six weeks. Some said less.

Vera Atkins had argued in the corridors of Baker Street that Noor Inayat Khan should not go. She had been overruled. The circuit needed an operator. Noor Inayat Khan had volunteered.

She had insisted, in her quiet way. She said she was ready. Now Vera Atkins stood beside her on the grass. She straightened the collar of Noor’s coat.

Noor watched her, calm. Her eyes were very dark and her voice very quiet. She was small. Vera Atkins put a hand into her pockets.

She found a thin envelope. She took it out. It was addressed to Noor’s mother. It was the letter to be posted in the event of something going wrong.

Noor said, gently, “You know I want it to reach her. ”

“I know,” Vera Atkins said. She put the letter in her own pocket. She thought she would keep it until Noor came back, so Noor could pay for the stamp herself.

“Empty your pockets,” she said. Noor complied. There was nothing else. Vera Atkins looked at her for a long time.

“There’s no need for you to go,” she said. “I know,” Noor said. “I mean it. Even now.

Even as you board the aircraft. It is not too late. ”

Noor looked at her and smiled. Briefly, she said, “I want to go.

”

Vera Atkins squeezed her hand. Noor climbed into the Lysander. By the summer of 1945, Vera Atkins knew that Noor Inayat Khan had landed near Angers on 16 June 1943. She knew that within days of her arrival, the Paris circuit she had been sent to had begun to be dismantled by the Germans, one arrest after another, a whole chain destroyed within two weeks.

She knew that Noor Inayat Khan had refused an offer to return to England. She knew that Noor Inayat Khan had continued working alone, with her wireless set, in a city where the Germans were now, more or less, looking for her personally. She knew that Noor Inayat Khan had been arrested in October 1943. She knew that at some point after the arrest, Noor Inayat Khan had escaped briefly from the building where she was held, and had been recaptured.

She knew that Noor Inayat Khan had been sent to a prison in Germany in November 1943, and held there for ten months, chained and in solitary confinement, denied all contact, listed as a prisoner deserving the severest treatment. She knew that at some point Noor Inayat Khan had been taken from that prison along with three other British women, who had been in solitary confinement in the same wing. In the summer of 1945 she did not know where the four of them had been taken. She did not know what had happened to them.

She began to search. She found the other three women first, because their fates were ultimately easier to determine. All three had been taken in September 1944 to the Dachau concentration camp near Munich. All three had been shot in the yard beside the crematorium immediately or shortly after arrival.

Their names were Yolande Beekman, Madeleine Damerment, and Eliane Plewman. Vera Atkins had seen them off from the airfield, too. She had straightened their collars. She wrote each of their fates into her book.

She did not linger. She had to find the fourth. She did not find Noor Inayat Khan at Dachau at first. The records listed the other three.

Noor’s name was not there. What she found showed that in September 1944 Noor Inayat Khan had not been at Dachau. She searched the other camps. Bergen-Belsen.

Mauthausen. Ravensbrück. She read the transfer documents from the civilian prison at Karlsruhe. The other three names were on the list.

Hers was not. She began to think that Noor Inayat Khan might have been separated from the other three earlier. She began to think that Noor Inayat Khan might have been killed somewhere else. She began to think that Noor Inayat Khan might be the one she would never find.

She would not accept that. Not yet. She kept searching. In early 1946, in a small room, she sat with a former employee of the civilian prison at Karlsruhe.

She asked, patiently, whether a prisoner named Nora Baker had been held there. For administrative reasons, Nora Baker was Noor Inayat Khan’s alias. The employee said yes. The employee said the prisoner had been kept in chains.

The employee said that on a certain day in September 1944, the prisoner had been transferred out. Where, the employee did not know. The transfer papers had gone with the escort. Vera Atkins wrote it down.

She looked elsewhere. In the records of the German security police, she found a list of prisoners transferred from Karlsruhe. Four names. She recognized three.

The fourth was Nora Baker. Above the list was written: Dachau. She went back to Dachau. She found the camp records.

She found the intake records for that day. Three names on the intake list. Not four. At first she did not understand.

She looked again. She went back over the papers. She traced the transfer chain. She found where and by whom the three had been shot.

She asked, calmly, who had been on duty at Dachau on the night of 12 September 1944. She got the names. She wrote them down. She began the interrogations.

Eventually she found a former camp official who had been on duty that night. She sat down with him. She asked him to describe what had happened that night. At first he did not want to.

He was reluctant. She did not push. She sat with him for a long time. She was patient, the way she always was.

Finally, after several hours, he told her about four prisoners. He said, “Four women. ” They had arrived in the night. He said one of them had been kept apart from the others.

He did not know why. He thought she might have been regarded as a special prisoner. He thought there may have been special instructions concerning her. He said the other three had been shot together in the morning.

The one kept apart had been shot alone, well before dawn. He gave the name of the officer who had done it. He gave the name as best he remembered. He did not remember every detail.

Vera Atkins wrote it down. Sitting in that small room, she did not let her expression change at all. She stayed sitting with him. She asked, quietly, what he knew about the prisoner who had been kept apart.

He said the girl was ill. She had been tortured on the journey. Her physical condition was bad. When she was taken into the yard, she said nothing.

Vera Atkins asked, quietly, whether the prisoner had said any word at all before she died. The officer thought for a moment. He said he could not remember. Then, after a pause, he said he thought—though he was not certain—that she had said a word.

He thought the word might have been in French. He thought the word was “liberté. ”

Vera Atkins wrote in her notebook: Nora Baker, true name Inayat Khan, executed at Dachau concentration camp, dawn of 13 September 1944, refused to give the names of her comrades, refused to give the name of her circuit, gave no name to the end. She closed the file.

She sat in the small room for a long time, remembering the young woman with the very dark eyes at the airfield in the summer of 1943, who had said, quietly, she wanted to go. The four at Natzweiler. The three at Ravensbrück. The four at Dachau.

And the rest—men shot in pits at Buchenwald, a young officer strangled in a corridor at Mauthausen, a wireless operator found dead at the foot of the stairs in Paris, whose cause of death would never be fully known. Her nine women at Ravensbrück. Four at Dachau. Four at Natzweiler.

Wherever she went, the notebook, the photographs, the small folder of final addresses and next of kin, and the unposted letters were in her handbag—letters that in some cases might still be needed, and in others could never serve again, because no relative was left alive. That autumn she was summoned to Nuremberg, to sit as the British representative while American interrogators questioned a specific prisoner. The prisoner was Rudolf Höss. Rudolf Höss had been commandant of the Auschwitz concentration and killing center from May 1940 to November 1943.

In that role he had been the directing hand in the murder of more than a million people. When Vera Atkins went to see him, he was a man in his forties, ordinary-looking, bespectacled, soft-spoken, a man who never raised his voice. In March 1946 he had been captured in hiding, betrayed by his own family, and brought to Nuremberg as a witness. When Vera Atkins entered his cell, he was not a defendant but a witness, because the Allies wanted his testimony against others before they hanged him, which they wanted and did.

His cell was bitterly cold, midwinter, cold stone walls, a small window, a table and two chairs. Vera Atkins wore her uniform. Technically she was a squadron officer in the Women’s Auxiliary Air Force. On paper she had no special authority to interrogate this man; she stood exactly where any other junior officer in the British zone stood.

Rudolf Höss had been commandant of Auschwitz. Vera Atkins was one of two people in the world who was going to hold Höss personally accountable for the matter of her women. When she entered, Höss looked at her and, by training, stood up. She did not tell him to sit.

She sat down herself first. She put her book on the table. She opened it. She looked at him.

She spoke in German. “I want you to tell me what happened at Auschwitz. ”

Rudolf Höss looked at her. He was no longer a resisting man.

Before she arrived, he had already given a written statement. In a sense, he had stopped fighting. He answered her. In a perfectly level voice, he described the arrival of the transports.

He described the selection process on the ramp. He described the two lines. He described the fate of the children. He described the buildings.

He gave the numbers of how many people could be killed per hour, per day, per week. He described the logistics of removing the bodies. He described the technical problems he had solved and the technical problems he had failed to solve. He described the statistical data.

He gave the totals, with small corrections here and there. Vera Atkins wrote down what he said. She did not interrupt. She did not raise her voice.

She did not ask him whether he was ashamed. She did not need to. That was for the court. When that was done, she asked him about specific transports.

She asked whether he remembered any small groups of women who had come separately, under the label Nacht und Nebel, rather than in the general deportations of Jews. He said such prisoners existed. He said he did not remember any of them individually. He said there had been so many prisoners.

She asked whether he had known, at any time, that there were British agents in his camp. He said that if any such prisoners existed, they would not have been treated differently. He said if they came in a transport, their fate would have been the same as everyone else in that transport. She wrote down what he said.

Then she asked him a series of questions about the procedures of the other camps. She asked about Natzweiler. She asked about Ravensbrück. She asked about Dachau.

She was trying to establish in the record that the commandant of one camp knew and understood how executions were carried out in the others, and that the orders to kill her women were not anomalies but routine. In his flat voice, he confirmed they were routine. She asked him for his personal opinion on the orders to kill prisoners by night, by injection or by shooting, and to give no word to the families. He said such orders were orders.

He said in the SS, an order was an order; no one questioned it. He said the orders came from high offices in Berlin. She wrote it down. She sat with him for hours.

At no point did she reveal what she was feeling. At no point did she reveal what she thought of him. She had been told by the American colonel who had interrogated him that Höss responded well to politeness but would become completely silent if pressed hard. She had said, very politely, that she knew that.

Thank you. She brought the politeness with her. Beneath it, she carried her own cold. At the end of the interview, she asked him one last question.

She asked whether he understood that the people killed in his camp and in the other camps he had described were human beings, individuals, with names, with mothers and children. He said yes, he said. He understood that. She asked whether he understood that it had been done to them as an injustice.

He hesitated. Finally he said that he now believed it had been an injustice. She closed her notebook. She stood up.

She walked out of the cell into the corridor. A British officer was waiting for her outside. He asked her later whether the interview had been useful. She said that it had.

Then he asked her what it had been like, sitting across from Rudolf Höss. She said, “Exactly what you would have expected. Let’s not talk about it now. ”

The trials continued, one after another.

The most important to her was the trial of the Natzweiler men. It was held in the summer of 1946 at Wuppertal, in the British zone. The defendants were the camp commandant, the camp doctor, the crematorium operator, and others implicated in the events of 6 July 1944. Vera Atkins was the officer who had assembled the case.

Vera Atkins gave evidence. Vera Atkins confirmed the identities of the four dead women. That identification was essential. The German defense claimed that no such women had been in the camp, or that if they had been, they were anonymous transit prisoners, or that they had been executed under lawful orders.

Vera Atkins submitted the papers from the civilian prison at Karlsruhe. She gave testimony. She produced the evidence of the prisoners who had been at Natzweiler that night and had seen the four women. She produced a woman who had been in the same cell as Andrée Borrel and her companions and could describe them specifically.

She submitted the photographs. She stood in the witness box and spoke quietly. She did not raise her voice. She was cross-examined at length.

She did not lose her temper. The defense tried to create doubt about the authenticity of the identifications. She answered every question in the same level tone. By then she was in her forties.

She was short and neatly dressed. The court accepted her as the proper authority on the four dead women. The verdicts were delivered. The commandant was sentenced to death.

The doctor was sentenced to death. The others received various terms of imprisonment. The crematorium operator’s testimony was complicated and contested, going one way at trial and another on appeal. Later that year and into the next, the executions were carried out at Hameln prison in the British zone.

Hameln was where the British zone’s condemned were taken. The hangman was a British executioner brought over from England. He was professional. He was skilled.

He knew his work. Vera Atkins was not usually present. She did not need to be. She was not that kind of person and had no need to become one.

But she made sure she was kept informed of the date and result in every case. She wrote, in her small and precise handwriting, beside the name of every agent, the outcome with the name of the killer. To the people who worked with her in those days, she did not seem different. She did not shut herself away, did not take time off, did not cry, did not drink.

In later years people imagined stories of what she had done. She did none of them. She drank tea. She wrote letters.

She worked on the next case. There was always a next case. More trials remained. The Ravensbrück trials remained, in Hamburg.

She gave evidence. The trials of the German security police officers remained, in Paris. At other courts, at other times, she presented evidence. Over and over, she fought to identify the women the Germans had tried to keep nameless.

Over and over, she refused to let them remain nameless. In the end, nine at Ravensbrück. Four at Natzweiler. So many others.

The men she had seen off from the airfield, even though the newspapers gave more attention to the women. The men shot in the mountain valley. The men worked to death in the tunnels. The men who died of typhus in the camp infirmaries in the last weeks of the war.

By the end of 1947 she had discovered the fate of one hundred and seventeen. One remained. She worked for the rest of her career on the one hundred and eighteenth. She never closed that file in her lifetime.

She insisted, to her superiors and to anyone else who raised the question, that the final file must stay open. She had never met many of their killers. Of those she had met, some were already on trial at Nuremberg, Hamburg, or Wuppertal for other crimes, and her people’s fates were tied to charges for which the men would have been hanged anyway. Some of the killers she had found herself, and sat across from at a table in a cold room, and asked in her quiet voice, in German, what exactly had happened, and on whose order, and on what date.

Some murderers got away—through amnesty, through the death of witnesses, through the loss of interest in war crimes trials in the late 1940s. Even for those, she did not give up. She wrote letters. She filed reports.

She sat in the small office at the back of her flat through the 1950s and 1960s, writing to the Foreign Office, to the West German authorities, to anyone who would read, about one or another unresolved case. Sometimes it worked. Most of the time it did not. In the last part of her life she lived in a small house in the south of England.

She kept the book. She kept every photograph. She kept the filing cabinet. At various points in her career she had been ordered to hand over parts of it.

She refused, in one way or another. The cabinet stayed with her. Visitors came. Some were the families of her agents.

A sister who once asked, plainly, how her brother had died. A daughter who once asked whether her mother had spoken of her. In the end, Vera Atkins told each of them what she knew. She always told them the truth, and she always told them as gently as she could, which in most cases was not gentle at all.

Journalists, writers, historians asked her, more than once, why she had done it. Why she had gone to Germany with no staff, no budget, no support. Why she had spent years chasing, at the cost of her own health, people whose fates she could not change. Why she had insisted when no one else had wanted to know.

She usually avoided answering. She was by nature a private person. She did not think she needed to justify her work to people who had not done it. But once, late in her life, a woman writing a book about her sat in her small sitting room and asked the question again, and waited without pressing.

Vera Atkins looked at the woman. Quietly, she said that she was the one who had said goodbye to them. She said she knew each of their real names. She said she knew who was waiting for them at home.

She said, if she had not gone to Germany and found out what had happened to them, no one would have done it. Their names would have been lost, the ones who killed them would never have answered for it, and the memory of what those young men and women were and did would have disappeared into the same night and fog the Germans had meant to put them into. She said, “I could not bear to give up their memory. ”

That was the whole of her statement.

Go back to the airfield. It is not 1943. It is not a night of war. It is now.

A grey afternoon in England. The grass runway is still roughly there, though tarmac covers most of it. There is a preserved hut, a small museum, and a low black stone. On the stone are carved the names of the men and women who left this field for occupied Europe.

There are many names. Some are French, some Belgian, some Norwegian, some Polish, some Dutch, some American. Many are English. In front of the stone, to those who have read this far, stands an elderly woman in an ordinary coat.

She is not actually visible, of course. She died years ago. She is buried elsewhere. Her ashes rest in a churchyard in the south of England, in a place she loved.

But she is still there, in front of the stone, because she was always there. She remembers the book. She remembers the photographs. She remembers the airfield, the aircraft, and the young people as they were.

She remembers Andrée Borrel’s shrug and her laugh, and the words “au bientôt. ” She remembers Violette Szabo’s photograph of her daughter in her pocket. She remembers Noor Inayat Khan, with the very dark eyes, saying in her calm voice, “I want to go. ” She remembers the one hundred and eighteen faces.

She remembers the one hundred and seventeen files, each closed, each with its date and place, and where possible its cause and the name of the executioner. She remembers the last file, the one she could never close. She remembers the question they asked her. Why did you do it?

She remembers her answer. She could not bear to give up their memory. The wind moves across the field. The pines at the far end of the runway stir.

The names on the stone are old now; the ink in the small museum’s register has faded, and the edges of the photographs have gone brown. A visitor walks past the stone without stopping. It is a Tuesday afternoon, many years after the war. But the woman who is not there still stands in front of the stone.

She has all the time she needs. She has been there for years. She has been there ever since the first name was carved. As long as people come to read the names, she will keep on.

She reads them, one by one, not in the order they are carved, but in the order she remembers them, the order in which she stood with each of them on the grass, straightened each collar, looked at each face, released each hand, and watched each aircraft go. She reaches the last one. She stops. She looks at the sky.

The sky is empty. She stands there for a long time. She stayed there. In the end, that is where she left them, and they left her, and that is where the story properly ends.

Not with the men she hanged. Not with the cold cell and Höss. Not with the four women in the crematorium. Not with the three in the small yard at Ravensbrück.

Not with the one who said “liberté” in the yard at Dachau before dawn. It ends where it began: on a grass field at night, a woman straightening a collar, taking a bus ticket from a pocket, squeezing a small hand, watching an aircraft go, and standing longer than anyone else—because in every case, she was the last person who knew who they really were. There were one hundred and eighteen of them, and she stood there for all of them.

She is still standing there.
