Marie-Laure sits on a bench beside the mollusk display and trains her ears on passing groups. A boy blurts, “They have a bomb called the Secret Signal. It makes a sound, and everyone who hears it goes to the bathroom in their pants!”

Laughter.

“I hear they give out poisoned chocolate.”

“I hear they lock up the cripples and morons everywhere they go.”

Each time Marie-Laure relays another rumor to her father, he repeats “Germany” with a question mark after it, as if saying it for the very first time. He says the takeover of Austria is nothing to worry about. He says everyone remembers the last war, and no one is mad enough to go through that again. The director is not worrying, he says, and neither are the department heads, so neither should young girls who have lessons to learn.

It seems true: nothing changes but the day of the week. Every morning Marie-Laure wakes and dresses and follows her father through Entrance #2 and listens to him greet the night guard and the warder. Bonjour bonjour. Bonjour bonjour. The scientists and librarians still collect their keys in the mornings, still study their ancient elephants’ teeth, their exotic jellyfish, their herbarium sheets. The secretaries still talk about fashion; the director still arrives in a two-tone Delage limousine; and every noon the African vendors still wheel their sandwich carts quietly down the halls with their whispers of rye and egg, rye and egg.

Marie-Laure reads Jules Verne in the key pound, on the toilet, in the corridors; she reads on the benches of the Grand Gallery and out along the hundred gravel paths of the gardens. She reads the first half of Twenty Thousand Leagues Under the Sea so many times, she practically memorizes it.

The sea is everything. It covers seven tenths of the globe . . . The sea is only a receptacle for all the prodigious, supernatural things that exist inside it. It is only movement and love; it is the living infinite.

At night, in her bed, she rides in the belly of Captain Nemo’s Nautilus, below the gales, while canopies of coral drift overhead.

Dr. Geffard teaches her the names of shells—Lambis lambis, Cypraea moneta, Lophiotoma acuta—and lets her feel the spines and apertures and whorls of each in turn. He explains the branches of marine evolution and the sequences of the geologic periods; on her best days, she glimpses the limitless span of millennia behind her: millions of years, tens of millions.

“Nearly every species that has ever lived has gone extinct, Laurette. No reason to think we humans will be any different!” Dr. Geffard pronounces this almost gleefully and pours wine into his glass, and she imagines his head as a cabinet filled with ten thousand little drawers.

All summer the smells of nettles and daisies and rainwater purl through the gardens. She and her father cook a pear tart and burn it by accident, and her father opens all the windows to let out the smoke, and she hears violin music rise from the street below. And yet by early autumn, once or twice a week, at certain moments of the day, sitting out in the Jardin des Plantes beneath the massive hedges or reading beside her father’s workbench, Marie-Laure looks up from her book and believes she can smell gasoline under the wind. As if a great river of machinery is steaming slowly, irrevocably, toward her.

Bigger Faster Brighter

Membership in the State Youth becomes mandatory. The boys in Werner’s Kameradschaften are taught parade maneuvers and quizzed on fitness standards and required to run sixty meters in twelve seconds. Everything is glory and country and competition and sacrifice.

Live faithfully, the boys sing as they troop past the edges of the colony. Fight bravely and die laughing.

Schoolwork, chores, exercise. Werner stays up late listening to his radio or driving himself through the complicated math he copied out of The Principles of Mechanics before it was confiscated. He yawns at meals, is short-tempered with the younger children. “Are you feeling okay?” asks Frau Elena, peering into his face, and Werner looks away, saying, “Fine.”

Hertz’s theories are interesting but what he loves most is building things, working with his hands, connecting his fingers to the engine of his mind. Werner repairs a neighbor’s sewing machine, the Children’s House grandfather clock. He builds a pulley system to wind laundry from the sunshine back indoors, and a simple alarm made from a battery, a bell, and wire so that Frau Elena will know if a toddler has wandered outside. He invents a machine to slice carrots: lift a lever, nineteen blades drop, and the carrot falls apart into twenty neat cylinders.

One day a neighbor’s wireless goes out, and Frau Elena suggests Werner have a look. He unscrews the back plate, waggles the tubes back and forth. One is not seated properly, and he fits it back into its groove. The radio comes back to life, and the neighbor shrieks with delight. Before long, people are stopping by Children’s House every week to ask for the radio repairman. When they see thirteen-year-old Werner come down from the attic, rubbing his eyes, shocks of white hair sticking up off his head, homemade toolbox hanging from his fist, they stare at him with the same skeptical smirk.

The older sets are the easiest to fix: simpler circuitry, uniform tubes. Maybe it’s wax dripping from the condenser or charcoal built up on a resistor. Even in the newest sets, Werner can usually puzzle out a solution. He dismantles the machine, stares into its circuits, lets his fingers trace the journeys of electrons. Power source, triode, resistor, coil. Loudspeaker. His mind shapes itself around the problem, disorder becomes order, the obstacle reveals itself, and before long the radio is fixed.

Sometimes they pay him a few marks. Sometimes a coal mother cooks him sausages or wraps biscuits in a napkin to take home to his sister. Before long Werner can draw a map in his head of the locations of nearly every radio in their district: a homemade crystal set in the kitchen of a druggist; a handsome ten-valve radiogram in the home of a department head that was giving his fingers a shock every time he tried to change the channel. Even the poorest pit houses usually possess a state-sponsored Volksemfänger VE301, a mass-produced radio stamped with an eagle and a swastika, incapable of shortwave, marked only for German frequencies.

Radio: it ties a million ears to a single mouth. Out of loudspeakers all around Zollverein, the staccato voice of the Reich grows like some imperturbable tree; its subjects lean toward its branches as if toward the lips of God. And when God stops whispering, they become desperate for someone who can put things right.

Seven days a week the miners drag coal into the light and the coal is pulverized and fed into coke ovens and the coke is cooled in huge quenching towers and carted to the blast furnaces to melt iron ore and the iron is refined into steel and cast into billets and loaded onto barges and floated off into the great hungry mouth of the country. Only through the hottest fires, whispers the radio, can purification be achieved. Only through the harshest tests can God’s chosen rise.
