“How do you know she told the truth about that?” Tony asked quietly. “She lied about being Soviet. She could have lied about anything else. Everything else.”

Ian turned the pen over again. “I think I need to have a chat with my wife,” he said at last.

Tony nodded. “After Altaussee?”

“Altaussee first.” The witness, the hunt, die J?gerin. Nothing came before that.

“You didn’t answer my question,” Tony said eventually. “What debt did you owe Nina that you married her without a second’s hesitation to get her to England?”

“Seb had promised to get her there. I kept his promise for him.” Ian looked at his partner. “He was my little brother. The only family I had left. And Nina watched die J?gerin murder him at Lake Rusalka.”

But the poisonous doubt had crept in. If she had lied about one thing, why not this? That night when Ian sat awake in his dark bedroom with his mind consumed by a woman, it wasn’t the huntress. He leaned on his windowsill with a half-smoked cigarette, looking out over moonlit Vienna and wondering, Who the hell did I marry?

Chapter 6

Nina

May 1937

Lake Baikal, Siberia

Nina broke the rabbit’s neck with a fast twist, feeling the last tremor of its heart under her fingertips. Spring had come to the lake, the air alive with the squeal and groan of ice as the lake’s surface broke apart into rainbow shards. Icicles dripped and water lapped on the shore as the air warmed, but ice floes still drifted in the farther depths. The Old Man had control of the seasons here, and he kept a long grip on winter.

Nina reset the rabbit snare under the trees. She was nineteen now, her blue eyes wary under a shapeless rabbit-fur cap, razor never far from her hand. Her father was too drunk much of the time now to set snares or to stalk game, so Nina did it. The rabbit in her hand would go into the stewpot, and the pelt could line a pair of gloves or be traded. Hunting let her make a living without a man, but Nina still glowered restlessly across the lake. It had been three years since she lay gasping on the ice with her eyelashes freezing together, looking up into the vast sky thinking Get out of here. Three years of waking up with the choking feeling of cold water closing over her head, the terrible drowning sensation. But where was there for a girl like her to go, little and wolverine-mad and knowing nothing except how to stalk and kill and move without a sound?

She didn’t know, but she had to find it, or else she would die here. Stay, and Nina knew the lake would take her in the end.

She stood swinging the dead rabbit by the ears and pondering her useless questions as she’d done for so many mornings, and the day might have ended as so many did: with her stamping back to the house, and skirting her father as he lay snoring. But today, Nina heard a rumble from the sky.

The gornaya? she wondered—but it was too early in the year for the mountain-bred wind that could whirl out of the northwest from a warm sky, whipping the lake into a frenzy and hurling waves three times the height of a man across the shores. Besides, this was a droning mechanical sound that seemed to rise from everywhere. Nina shaded her eyes, hunting for the strange buzz, and her jaw dropped as a shape rose sleek and dark from the horizon and glided down over the trees. An airplane? she thought. The village traders who had been to Irkutsk claimed to have seen them, but she never had. It might as well have been a firebird rising from myth.

She thought it would streak across the sky and be gone, but there was a skipping sound in the drone of its engines. Nina had a moment’s terror the machine would crash into the lake. But it banked stiffly, descending below the tree line, and Nina began to run. For once she didn’t bother to move quietly, just crashed through underbrush and squelching mud. At some point she realized she had lost the rabbit, but she didn’t care.

The plane had touched down in a long clearing in the taiga. The pilot was standing by the cockpit with a toolbox, cursing, and Nina stared at him, mesmerized. He looked as tall as a god in his overalls and flying cap. She didn’t dare come closer, just sank to her heels in a stand of brush and watched him work on the engine. She couldn’t stop looking at the plane, its long lines, its proud wings.

It took her a long time to work up the courage to approach. But she moved out from the brush, slowly came forward. The pilot turned and found Nina under his nose.

He jumped back, boots slipping in icy mud. “Fuck your mother, you scared me.” His Russian was clipped, strangely accented. “Who are you?”

“Nina Borisovna,” she said, dry mouthed. She raised a hand in greeting, and saw his eyes dance over the dried rabbit blood showing under her nails. “I live here.”

“Who lives in a mud splat like this?” The pilot looked at her a little longer. “A real little savage, aren’t you?” he said, turning back to his toolbox.

Nina shrugged.

“This isn’t even Listvyanka, is it?”

“No.” Even Listvyanka was bigger than her village.

The pilot swore some more. “Hours off course from Irkutsk . . .”

“Planes don’t land here,” Nina managed to say. “Where are you from?”

“Moscow,” he grunted, slinging tools. “I fly the mail route, Moscow to Irkutsk. Longest route in the Motherland,” he added, unbending. “Detoured past Irkutsk in the fog, had some engine trouble. Nothing serious. I could fly this girl home on one wing if I had to.”

“What kind of—I mean—” Nina wished she could stop blushing and stammering. She could have eaten the local boys for breakfast, but here she was tripping over her words like a lovesick girl. Only she wasn’t in love with a man, but a machine. “What kind of plane is this?”

“A Pe-5.”

“She’s beautiful,” Nina whispered.

“She’s a brick,” the pilot said dismissively. “But a good Soviet brick. Eh, get back, little girl!” he barked as Nina reached toward the wing.

“I’m not a little girl,” she flashed. “I’m nineteen.”

He chuckled, went on working. Nina wished she understood what he was doing. She could have opened up a rabbit or a seal or a deer and known every organ and bone, but the Pe-5’s innards were strange to her. Masses of wires and gears, the smell of oil. She breathed it in as though it were wildflowers. “Where did you learn to fly?”

“Air club.”

“Where are there air clubs?”

“Everywhere from Moscow to Irkutsk, coucoushka! Everybody wants to fly. Even little girls.” He winked. “Ever heard of Marina Raskova?”

“No.”

“An aviatrix who just set the distance record. Moscow to . . . Well, somewhere. Comrade Stalin himself sent congratulations.” Another wink. “Probably because she’s pretty, Raskova is.”

Nina nodded. Her heart had stopped its pitter-pat, settled to a purposeful rhythm. “Take me with you,” she said when he finally shut up his toolbox and rose. She wasn’t surprised when he guffawed. “Just an idea. I’m a good screw,” she lied. She hadn’t screwed a man before—most of the ones she knew were nervous around her, and anyway she was too wary of getting pregnant—but she’d do it right here in this clearing if it got her into that plane.

“A good screw?” The pilot looked at the blood under her fingernails. “Do you pick your teeth with a man’s bones afterward?” He shook his head, stowing his tools. “Good luck, coucoushka. You’ll need it, stuck out here on the edge of the world.”

“I won’t be stuck here much longer,” Nina said, but he was swinging up into the cockpit and didn’t hear. Before he could start up the engines, she darted close and laid her hand against the wing. It seemed warm to her, pulsing under her palm like a living thing. Hello, it seemed to say.

“Hello,” Nina breathed back, and she darted away before the pilot could shout at her. She raced to the edge of the clearing as the deafening sound of the engines filled the air and sent birds spiraling up from the trees. Then she watched, delighted, as the plane slowly turned toward the long treeless edge, straightened, began to gather speed. Her breath caught when it lifted into the air, rising into the pool of blue that was the sky—aiming west. She stood there long after it had disappeared, crying a little, because at last she had answers.

What is the opposite of a lake?

The sky.

What is the opposite of drowning?

Flying. Because if you were soaring free in the air, water could never close over your head. You might fall, you might die, but you would never drown.

What lies all the way west?

An air club. Maybe it wasn’t all the way west, but just a few hours west lay everything Nina had not known she needed.

She ran all the way home, feet already so light she could feel herself straining to take wing, and packed everything she owned—a few clothes, her identity cards, the razor—into a satchel. Without hesitation, she emptied every kopeck out of the jar her father kept as a money tin. “I’ve been making all the money anyway,” she told her father, snoring on his filthy bed. “Besides, you tried to drown me in the lake.”
