Read Chapter 22: The Sister's Sacrifice

The knock came at half past six, before the gas lamps had been lit. Evelyn opened the door to find Margaret on the step, rain beading on the shoulders of her dark traveling coat, a leather satchel clutched to her chest like a shield.

“Maggie.” Evelyn stepped back, surprise flattening the greeting. “You didn't write. I thought you were in Hampshire.”

“I was.” Margaret stepped inside, trailing the smell of wet wool and coal smoke. She did not embrace Evelyn. She never did anymore, not since the war had made them strangers to each other. “I came up on the night train. There was no time to write.”

Evelyn closed the door and lit the lamp. In its glow Margaret looked older than her twenty-four years—sharp angles where there had once been softness, shadows beneath eyes that had always been quick to laugh. She was still in her VAD uniform beneath the coat, the red cross of her apron creased and travel-stained.

“What's happened? Is it Mother—?”

“Mother is fine.” Margaret set the satchel on the table, unclasped it with deliberate care. From inside she withdrew a single sheet of paper, creased down the middle, and slid it across the scarred oak. “This came three days ago.”

Evelyn read it standing. The letter was brief, official, stamped with the War Office seal in smudged blue ink. It authorized Margaret Hartley to proceed to Boulogne, where she would be attached to the 24th General Hospital as a nursing sister for a period not exceeding eight weeks, with transport provided by military rail.

“This is a joke,” Evelyn said, though Margaret's face told her it was not. “You have no military training. You've never been out of the country. They wouldn't send you to the front to empty bedpans.”

“They would,” Margaret said quietly, “if I asked them to.”

Evelyn lowered the letter. The lamplight caught the angle of her sister's jaw, the stubborn set of her mouth—the same expression she'd worn at twelve when she'd climbed the church tower at St. Mary's to prove she wasn't afraid of heights. Margaret had never been afraid of anything. That had always been Evelyn's job.

“You asked them.”

“I volunteered.” Margaret's hands were steady as she folded the letter and returned it to the satchel. “They took me. They were glad to have me.”

“You hate blood. You fainted when I cut my finger with Father's razor.”

“I was nine years old.”

“Margaret.” Evelyn heard her own voice rising, thin and sharp. “What is this? Why would you—why would you *do* this? You have a position at Holloway. You have patients here who need you. You have—” She stopped, because the next words were too cruel to say: *You have nothing to gain and everything to lose.*

Margaret looked at her for a long moment. Then she said, in a voice gone flat and careful, “I have debts, Evelyn.”

The room went quiet. Outside, a cab rattled past, wheels hissing on wet cobbles.

“What debts?”

“You think I don't know.” Margaret's eyes were bright, too bright, but she did not look away. “You think I didn't notice the money that appeared in Mother's account after Father died, or the letters you stopped writing home when you thought no one was watching, or the way you flinched when I asked what you actually did at Admiralty House.”

Evelyn felt the breath leave her body through her teeth. “Maggie, you cannot—I never told you because it's not safe for you to know. The work I do is secret. It's *treason* to speak of it.”

“I know what you do.” Margaret's voice dropped to barely a whisper. “I know you read German messages. I know you broke the code that stopped a U-boat attack on the Channel convoys in February. I know there is a man named Valdemar Krueger who has been trying to kill you since Easter, and that you've been meeting with an intelligence officer named Ashworth on rooftops in the middle of the night.”

The words fell like stones into still water. Evelyn could not speak. She could only stare at her sister, at the stranger who wore Margaret's face.

“How,” she managed at last. “How could you possibly know any of that?”

“Because someone told me.” Margaret's voice cracked on the last word. She reached into the satchel again, withdrew a second envelope, and held it out. “I was told to deliver this to you. I was told that if I did, my debt would be cleared. That I would be allowed to come home.”

Evelyn took the envelope. It was plain cream, unmarked, sealed with red wax. No insignia. No sender.

She broke the seal with shaking hands.

The message inside was written in a hand she knew as well as her own. Edward's. The same sloping cursive she had seen in his letters from the front, the same unsteady pressure on the ascenders that betrayed a left-handed boy forced to write right-handed.

*Evelyn—*

*If you're reading this, Margaret has kept her word. I know what you've become, and I know what you want. Thomas is alive, but he is not the man you remember. He is in Le Touquet, in a house on the Rue de la Paix, guarded by three men who report to Krueger. If you want to find him before the Meridian sails, you must stop looking at ships and start looking at people.*

*I cannot tell you who to trust. I can only tell you that the person who sent me this letter is not your enemy.*

*Come to France. Bring your sister. She is the only one who can get you through the lines.*

*Your brother,* *Edward*

Evelyn read it twice. Then she read it a third time, trying to find the trick, the trap, the thread that would unravel the whole thing. There was none. It was just words. Just her brother's hand, reaching across the Channel to offer her a road she had not known existed.

“This is from the War Office,” she said slowly, tapping the first letter. “They authorized you to go to France because Edward arranged it.”

“Yes.”

“And the second letter—the one you were told to deliver—came from Edward directly.”

“It came through a woman named Fenmore.”

Evelyn's blood went cold. She looked up sharply. “Lady Fenmore gave you this?”

“Not personally. It came with instructions. A relay—a man in a blue coat in the railway station in Winchester. He told me to bring it to you, that you would know what to do with it, and that if I did, the debts I owe would be forgiven.”

“What debts?” Evelyn asked again, quieter this time. “Maggie, what did you do? What did you borrow?”

Margaret's face crumpled. For a moment she was fourteen again, standing in the doorway of their father's study after he'd died, asking what would happen to them now. Evelyn had lied to her then, told her everything would be all right. It had been the first lie she ever told her sister.

She had been lying ever since.

“I was so angry at you,” Margaret whispered. “After you left. After you stopped writing. I thought you had abandoned us. That you didn't care about who had died or why. And I—I made a mistake. I wrote to a man who contacted me at the hospital. He said he was an intelligence officer. He said he could help me find out what you were really doing.”

“What man?”

“I don't know his name. He wore a pin in his lapel—a cypher, you know, a little gold key. He said he worked at the Foreign Office. He gave me money. I didn't—I didn't think it was wrong. I just wanted to know the truth about you.”

Evelyn felt the room tilt. The gold key. The same pin Griffiths had worn, the one she'd noticed in her first week at Room 40.

“Maggie.” She took her sister's hands. They were cold and trembling. “You have been used. By the same people who killed my friends, who tried to kill me. The money they gave you was not a loan. It was a leash.”

Margaret blinked, tears spilling over at last. “I know. I figured it out too late. That's why I came to you. Because I don't know who else to trust.”

Evelyn looked at the envelope in her hand. Then at the authorization letter on the table. Then at her sister's face, pale and desperate and so achingly young.

She thought of the Meridian, sailing in four days. She thought of Thomas, alive somewhere in Le Touquet, guarded by men who reported to a cryptographer who wanted her dead. She thought of Ashworth, waiting for her at St. Dunstan's chapel, unaware that his plan was already obsolete.

“You said you have debts,” Evelyn said quietly. “If you want to clear them, you're going to help me do something. Something that will get us both killed if it goes wrong.”

Margaret wiped her eyes with the back of her hand. She did not ask what it was. She did not ask if there was another way.

She simply said, “When do we leave?”
