But no. Surely not. Surely I’m only imagining this, surely I’m only seeing a resemblance because I want to see one. After all, it’s impossible, isn’t it? Margaret Thorpe won’t receive my letter until this evening, when she arrives home from whatever government building she inhabits during working hours. So this woman can’t be her, cannot possibly be my husband’s sister, however much the sight of those eyebrows sets my heart stuttering. Anyway, her head’s now turned toward the clerk, and from this angle she looks nothing like Thorpe, not at all. Unless—

The bell jingles again, dragging my attention back to the entryway. Another draft follows, and a man shambles past the door in a damp overcoat of navy blue, a hat glittering with mist. His face is pockmarked, the only notable thing about him. He casts a slow, bland expression around the room, and it seems to me that he takes in every detail, every flock on the wallpaper and spot on the upholstery, until he arrives, quite by accident, on me.

The woman’s still addressing the clerk. No notice of us at all. I climb to my feet. “Mr. B—?”

He steps forward and holds out his hand. “You must be Mrs. Thorpe,” he says warmly, and he takes my fingers between his two palms, as if we are father and daughter, meeting for tea after a short absence.

Instead of remaining inside the Basil Hotel foyer (in which the enemy ears might or might not be listening, but the desk clerk certainly is) we head out into the gloom. I tend to step briskly as a matter of habit, but Mr. B— (I’m afraid I can’t reveal his real name) shuffles along at an awkward gait, and it’s a chore to keep my limbs in check. I tuck my hands inside my pockets and drum my fingers against my thighs. I feel as if he should speak first. He’s the professional, after all.

“Well, Mrs. Thorpe,” he says at last. “I must congratulate you on your resolve. To have made your way to London in wartime, to have approached my office with such an extraordinary request—why, it’s the most astonishing thing I’ve seen in some time.”

“I hope you don’t mind.”

“Mind? Of course not. If there’s one thing we admire in this country, it’s dash. Dash and pluck, Mrs. Thorpe, which you appear to possess in abundance. How long had you two been married?”

“Since July.”

“This past July?”

“Yes. The seventh.”

“Ah. Just before he was captured, then. How dreadful.”

“It was months before I had any word at all. At first, I thought he’d been called out on another of his—whatever you call them—”

“Operations?”

“Yes, operations. But when he didn’t return . . .”
