Read Chapter 5: A Sister's Debt

Rain had settled over London by the time Margaret arrived, a thin miserable drizzle that turned the streets to oiled silk. Evelyn met her at the door of the boarding house with a lamp held high, and there was her sister, suitcase in hand, cap askew, looking like she had walked the whole way from the hospital.

“You look terrible,” Evelyn said.

“Charming as always.” Margaret stepped inside and shook water from her coat. “The train was held up at Reading. Something about a troop movement. I stood on the platform for two hours.” She glanced around the narrow hallway, then at Evelyn. “You’ve lost weight.”

“You’ve lost colour.”

“Nursing does that.” Margaret smiled, but it didn’t reach her eyes. “Is there tea?”

Evelyn led her up to the small sitting room she shared with two other girls, both out for the evening. She set the kettle on the gas ring and busied herself with cups while Margaret peeled off her wet things and hung them by the fire. The room filled with the smell of damp wool and coal smoke.

“I know I wrote rather suddenly,” Margaret said. “But the hospital released me for a week’s leave, and I couldn’t bear the thought of staying in that billet alone. The other nurses have all gone home.”

“You’re welcome here as long as you need.” Evelyn poured the tea. “Though I should warn you, the landlady is a stickler about visitors before nine.”

“Then I’m glad I’m late.” Margaret took the cup, cradling it in both hands. She studied Evelyn over the rim. “You look thin too. Are they feeding you at that office of yours?”

“They feed us enough.”

“That’s not an answer.”

Evelyn sat in the chair opposite. Her sister had always been the blunt one, the one who spoke plainly and asked the questions no one else dared. It was Margaret who had held her hand at their mother’s funeral, Margaret who had told her to leave the countryside and make something of herself in London, Margaret who had written to her, week after week, in the months Thomas had been missing.

“I’m fine,” Evelyn said. “Work is demanding, but it’s good. Useful.”

“Still translating?”

“Something like that.”

Margaret narrowed her eyes. They had never quite lied to each other, and Evelyn felt the weight of that unbroken trust now, pressing on her chest. She could not tell Margaret about Room 40. Could not tell her about the intercepts, about the name Singbird blinking up at her from coded German text. Could not tell her that she had found a memorandum in the War Office signed by Margaret herself, tying her sister to Commander Ashworth and a pocket watch engraved with a symbol that matched a traitor’s routing mark.

So she said nothing, and the silence stretched between them like a wire.

“I brought something,” Margaret said at last. She set down her cup and reached for her suitcase, unbuckling the straps with tired hands. “I’ve been holding it for you. I thought you might want it back now.”

She lifted out a folded Army greatcoat, heavy wool the colour of wet slate. Evelyn knew it before Margaret even held it up. The cut, the brass buttons, the faint tear at the left shoulder where Thomas had caught it on a fence climbing out of a field near Dover.

“I found it in Father’s attic,” Margaret said. “Thomas left it there the last time he visited. I thought—well. I thought you might want it.”

Evelyn’s throat tightened. She took the coat carefully, running her hand over the wool. It smelled faintly of cedar and pipe smoke, and underneath that, something she could not name. Something like him.

“Thank you,” she managed.

“It’s only a coat, Ev.”

“No. It’s more than that.” She folded it over her arm and pressed the fabric to her chest for a moment, then forced herself to breathe. “I’ll hang it in my room. It can use the airing.”

Margaret watched her with a knowing look, but said nothing. She finished her tea and stood, stretching. “I’m dead on my feet. If you can point me to the bed?”

“Mine. I’ll take the floor.”

“Don’t be daft. We can share.”

Evelyn led her upstairs, hung the coat on the hook behind her door, and lay down beside her sister in the narrow bed, staring at the ceiling. Margaret’s breathing evened out quickly, the deep sleep of someone who had spent her days on a hospital ward and her nights lying awake for the sound of ambulances.

Evelyn did not sleep. She lay still, listening to the rain and the distant rumble of traffic, thinking about the coat. Thomas had given her the brooch before he disappeared, hidden with a cipher on its back. He had left the coat at her father’s house, in the attic, where Margaret had found it. As if he had been shedding his belongings, one by one, preparing for something.

The memorandum was still in her skirt pocket, a folded square of paper she had carried with her for days. She had read it so many times she had memorised it. *The engraved watch shall serve as proof of identity. Should the bearer present it, all questions are answered and he is to be granted every access.*

Signed: *M. Hartley, Nursing Sister, att. War Office Liaison.*

Margaret, who was sleeping beside her, had signed a document about a pocket watch that matched the symbol on a German intercept. Margaret, who had written to Evelyn every week since Thomas disappeared. Margaret, who had just travelled to London from her hospital billet, carrying Thomas’s coat like an offering.

In the morning, Evelyn woke before dawn. Margaret was already dressed, standing at the window in the grey light.

“I’m sorry if I was strange last night,” Evelyn said, sitting up.

“You weren’t strange.” Margaret turned. “You were guarded. There’s a difference.”

“Is there?”

“Yes. Strange is when someone asks you something and you don’t know the answer. Guarded is when you do know and you won’t say.” Margaret fixed her cap in the mirror. “I’d rather you be strange, Ev. Guarded suits you poorly.”

Evelyn stood and went to her. “I’m just tired. The work is—” She stopped. Margaret’s expression had shifted, something catching her attention beyond the window.

“What is it?”

“That man.” Margaret nodded toward the street below. “He’s standing by the lamp post across the road. He was there when I arrived last night.”

Evelyn moved to the window. The street was empty now, save for a costermonger with his cart. “I don’t see anyone.”

“He’s moved on. But he was there. Same coat, same hat. I saw him near the War Office two days ago, when I went to collect my papers. I couldn’t place him then either.” Margaret frowned. “He was watching the building. Quite a long time. I thought it odd.”

Evelyn’s heart beat faster. “What did he look like?”

“Tall. Broad shoulders. Grey at the temples. The kind of face you forget and can’t forget at the same time.” Margaret turned from the window. “Why? Do you know him?”

“No,” Evelyn said, too quickly. “No. I’m sure I don’t.”

But she had seen the memorandum. And she had seen the pocket watch. And she knew that if Margaret had seen a man near the War Office, a man she could not place, a man with grey hair and a forgettable face, that man was probably not worth forgetting.

He was worth finding.

Margaret studied her for a long moment, then shook her head. “You’re lying to me, Ev. But I’ll let it pass for now.” She picked up her handbag. “I’m going to find a chemist. I need bandages and iodine for the hospital stores. I’ll be back before lunch.”

She paused at the door. “Whatever you’re doing, whatever they have you doing in that office of yours—be careful. The coat isn’t the only thing Thomas left behind.”

Evelyn waited until her sister’s footsteps faded down the stairs. Then she went to the window and looked out at the empty street, at the lamp post where Margaret had seen a man watching the house. Someone was watching her. Someone had been watching her sister.

And Thomas’s coat hung on the back of her door, heavy with wool and secrets.

She crossed to it, lifted the collar, and felt along the lining with careful fingers. There was something stiff in the hem. She worked it free and held it up to the morning light.

A small card, worn at the edges. On it, in Thomas’s hand: *Ask Margaret about the nightingale.*

Evelyn stood very still, the card burning in her palm.

The keeper of names. The Songbird. Her sister’s signature on a War Office memorandum.

And now a message from a dead man, hidden in the lining of a coat he had left behind.
