Read Chapter 2: Room 40

The morning fog had not yet lifted when Evelyn presented herself at the Admiralty’s unmarked side entrance, the one Commander Ashworth had sketched on a scrap of paper that now felt damp and soft in her gloved hand. A porter with a face like carved oak checked her name against a ledger, nodded once, and gestured toward a stairwell that seemed to descend into the very bowels of the building.

She had expected more ceremony for the heart of Britain’s secret war—guards, passwords, perhaps a great iron door. Instead, she found a narrow corridor lined with green painted walls, lit by gas jets that hissed like disapproving old women. The air smelled of floor polish, wet wool, and something else she couldn’t place until she recognized it: the sharp tang of ozone and overheated machinery.

Room 40 was not a room at all, but a warren of adjoining offices knocked through into one long, low-ceilinged cavern. Desks stood in neat rows like tombstones, each occupied by a woman bent over paper or a typewriter. The windows here were useless—painted over, then boarded, then hung with blackout curtains as if someone had wanted to be triply certain no hint of light or work might escape. Gas lamps hissed overhead, casting a sickly yellow glow that made every face look vaguely jaundiced.

A thin woman with spectacles perched on a sharp nose rose from a desk near the door. She wore a high-collared blouse and a cameo brooch, and she regarded Evelyn with the weary authority of someone who had seen too many bright young women arrive and too few of them last.

“You’ll be Hartley,” she said. Not a question.

“Yes. Commander Ashworth—“

“Commander Ashworth is not here.” The woman’s tone suggested this was a mercy. “I am Miss Clements. You will call me Miss Clements. You will report to me at nine each morning. You will not speak of your work to anyone, including the other girls, except as necessary for the work itself. You will not take anything from this room, including scraps of paper, pencil shavings, or—I cannot stress this enough—your own thoughts.”

Evelyn blinked. “My thoughts?”

Miss Clements’s mouth twitched, almost imperceptibly. “You’d be surprised how many girls think they can keep a German code sequence in their head and hum it on the omnibus home. We had one who wrote a letter to her mother about the “lovely patterns” she saw in her work. Her mother was very proud. Her mother also received a very stern visit from a gentleman in a long coat.” She paused. “The girl was dismissed. The mother now believes her daughter works in a wallpaper factory.”

A nervous giggle escaped from a nearby desk, quickly stifled. Miss Clements did not look in that direction, but her posture said she had catalogued the offender for future reference.

“You’ll be on transcription,” Miss Clements continued, leading Evelyn deeper into the room. “We have three shifts of listeners in the wireless intercept huts, and they send us reams of raw traffic. Your job is to take the shorthand and the garbled Morse and make it legible. Legible, Hartley, not interpreted. The interpreters are upstairs, and they are not you. If you see something that looks remarkable, you will note it in your log and move on. You will not—I repeat, not—follow threads on your own initiative. Is that clear?”

“Yes, Miss Clements.”

The lie sat easily on Evelyn’s tongue. She had spent six months translating French poetry for a Bloomsbury publisher before the war; she had learned long ago that editors and supervisors were best managed with polite acquiescence and then doing exactly what one pleased.

Miss Clements assigned her to a desk in the third row, between a girl named Rose who smelled of lavender and another named Alice who smelled of printer’s ink and seemed to have developed a permanent squint. The desk held a stack of foolscap, a pen, a pot of ink, and a brass lamp that wobbled when Evelyn touched it.

“Start with yesterday’s afternoon batch,” Alice said without looking up. “The handwriting gets worse as the shift wears on. If you can read that, you can read anything.”

Evelyn sat. The chair was hard, the desk was scarred with the initials of previous occupants, and across the room a telephone rang with a sound like a trapped wasp. Miss Clements answered it, listened, said “Yes, sir,” and hung up. The rhythm of the room settled around Evelyn like a familiar coat: the scratch of pens, the occasional rustle of paper, the low murmur of women reading aloud to themselves as they worked.

She picked up the first page of the batch. The intercept was written in a hasty, cramped hand—the shorthand of a wireless operator who had been copying station traffic for hours. The message itself was in German, a routine naval communication about supply ships and weather conditions. Evelyn translated it in her head without effort, transcribed the clean English version onto her foolscap, and reached for the next page.

For an hour, the work was numbing. Convoy positions. Weather reports. A request for replacement parts for a wireless transmitter. She filled three pages with neat, precise transcriptions and felt the strange satisfaction of a puzzle solved, even if the puzzles were mundane. The gas lamps hissed. Rose’s lavender perfume drifted past. Somewhere behind her, a woman laughed softly at a joke Evelyn couldn’t hear.

Then she turned to the next page in the batch, and the world went very quiet.

The handwriting was different from the others—firmer, less hurried, as if the sender had deliberately taken his time. The message was in the same naval code she had seen a hundred times that morning, but the content was not routine. It was a fragment, broken off mid-transmission, as if the operator had been interrupted:

*...confirm identity of SINGBIRD. The lists she seeks are in the possession of...*

Evelyn’s pen hovered over the paper. The message was in German, but the word was in English—deliberately, she knew, because the German text surrounded it like water around a stone. SINGBIRD. A typo, perhaps, for SONGBIRD. The intercept operators were not always careful.

Or perhaps not. Perhaps the sender had misspelled it deliberately, the way one might disguise a signature in a crowd.

Her heart had begun to beat very fast, a drum under her ribs. She forced herself to breathe slowly, to keep her face still, to be just another girl doing her transcription on a grey London morning. She read the fragment again.

*...confirm identity of SINGBIRD. The lists she seeks are in the possession of...*

The lists she seeks. Thomas’s note in her drawer at home—the one Commander Ashworth had somehow obtained, the one that had made her accept this post without a second thought—had said: *Evelyn, find the Songbird. The lists will find you.*

She had assumed Thomas meant her own pet name, the one he had given her in a punt on the Cherwell years ago, when she had sung a Scottish folk song off-key and he had laughed and called her his songbird. The note had read like a love letter, a coded assurance that he was alive and thinking of her.

But this message suggested something else. Something colder. Someone else was called Songbird. Someone whose identity was being confirmed by a German wireless operator in a transmission that had broken off mid-sentence.

And whoever it was, Thomas had told her to find them.

Her pen moved, almost of its own accord, and transcribed the fragment cleanly onto her foolscap. Her handwriting did not waver. Her face did not twitch. She had learned, in that Bloomsbury publisher’s office, to hide her excitement when she found a brilliant new poet, and the skill served her now.

“Anything interesting?” Rose asked, leaning over slightly.

Evelyn smiled, a placid, tired smile. “Supply ships again. The Germans are very worried about their bacon ration.”

Rose laughed and turned back to her own work. Evelyn’s heart was still pounding, but she kept her hands steady. She copied the rest of the message—what little survived the interruption—transcribed it neatly, and placed it on the stack for the interpreters upstairs. She did not underline the word SINGBIRD. She did not dog-ear the corner. She did nothing at all that might flag the page for a second glance.

But she committed it to memory. Every letter. Every pause. She would not hum it on the omnibus; she was not that kind of fool. But she would not forget it either.

The morning crawled past. She transcribed German weather reports and convoy coordinates, requests for spare parts and complaints about cold coffee. She learned the names of her neighbours—Rose was engaged to a soldier in France, Alice had a father who owned a print shop, the girl with the stifled laugh was called Margaret and had once been a governess in Berlin. They were ordinary women with ordinary lives, and they had no idea that one of their own was sitting among them, holding the key to something that might unravel the entire war.

At one o’clock, Miss Clements dismissed them for lunch in shifts. Evelyn declined the offer to join the others in the canteen—she claimed a headache, asked for a glass of water, and sat alone at her desk with the stack of unfinished transcription.

The moment Rose and Alice were out of sight, she pulled the intercepted fragment back from the pile. It was a risk. Miss Clements had been explicit about not following threads. But the word SINGBIRD burned in her memory, and she needed to see it again in the original, to read the German syntax around it, to find any clue about who this Songbird might be.

The message was addressed to a station in Bruges. The sender’s signature was a merchant shipping code, unlikely to be a single individual. The phrase *the lists she seeks* suggested the interlocutor was female—at least, that was the pronoun the German used. *Sie.* She.

She read the fragment three times, then replaced it exactly as she had found it. Her hands were shaking slightly, and she pressed them flat against the desk to still them.

Somewhere in London, she thought, there was a woman who was being called Songbird. And somewhere in Germany, there was a wireless operator who was trying to confirm her identity. And Thomas—her Thomas, who had vanished six months ago without a word—had known about this woman, and had told Evelyn to find her.

Why? Why her? What did she have to do with whatever thread connected them?

A shadow fell across her desk. She looked up, expecting Miss Clements, already rehearsing an excuse for lingering over her lunch break.

But it was not Miss Clements. It was a man in civilian clothes—a dark suit, a sober tie, a face she recognized from the photographs in the newspapers but could not quite place. He was tall, clean-shaven, with eyes that had the grey, assessing quality of a winter sea.

“Miss Hartley,” he said. It was not a question.

“Yes.”

“Commander Ashworth sends his compliments. He asks that you join him for tea this afternoon at half past three. Room 309. Please do not be late.”

He did not wait for an answer. He turned and walked out of Room 40, leaving Evelyn alone with the humming gas lamps and the fragment of German code and the terrible, thrilling certainty that her first day had already become something far more complicated than she had ever imagined.
