the trenches, short-lived stars suspended in the air from parachutes, meant to illuminate possible targets for snipers. Every soldier within reach of the glare would freeze while it lasted. Some hours, eighty or ninety of these flares would go off, one after another, and the night would turn stark and strange in that magnesium glow. It would be so quiet, the only sound the fizzling of the flares, and then you’d hear the whistle of a sniper’s bullet streak out of the darkness and bury itself in the mud. We would stay as close together as we could. But I’d become paralyzed sometimes; I could not move any part of my body, not even my fingers. Not even my eyelids. Henri would stay right beside me and whisper those scripts, the ones we recorded. Sometimes all night. Over and over. As though weaving some kind of protective screen around us. Until morning came.”
“But he died.”
“And I did not.”
This, she realizes, is the basis of his fear, all fear. That a light you are powerless to stop will turn on you and usher a bullet to its mark.
“Who built all of this, Uncle? This machine?”
“I did. After the war. Took me years.”
“How does it work?”
“It’s a radio transmitter. This switch here”—he guides her hand to it—“powers up the microphone, and this one runs the phonograph. Here’s the premodulation amplifier, and these are the vacuum tubes, and these are the coils. The antenna telescopes up along the chimney. Twelve meters. Can you feel the lever? Think of energy as a wave and the transmitter as sending out smooth cycles of those waves. Your voice creates a disruption in those cycles . . .”
She stops listening. It’s dusty and confusing and mesmerizing all at once. How old must all this be? Ten years? Twenty? “What did you transmit?”
“The recordings of my brother. The gramophone company in Paris wasn’t interested anymore, but every night I played the ten recordings we’d made, until most of them were worn out. And his song.”
“The piano?”
“Debussy’s ‘Clair de Lune.’ ” He touches a metal cylinder with a sphere stuck on top. “I’d just tuck the microphone into the bell of the gramophone, and voilà.”
She leans over the microphone, says, “Hello out there.” He laughs his feathery laugh. “Did it ever reach any children?” she asks.
“I don’t know.”
“How far can it transmit, Uncle?”
“Far.”
“To England?”
“Easily.”
“To Paris?”
“Yes. But I wasn’t trying to reach England. Or Paris. I thought that if I made the broadcast powerful enough, my brother would hear me. That I could bring him some peace, protect him as he had always protected me.”
“You’d play your brother’s own voice to him? After he died?”
“And Debussy.”
“Did he ever talk back?”
The attic ticks. What ghosts sidle along the walls right now, trying to overhear? She can almost taste her great-uncle’s fright in the air.
“No,” he says. “He never did.”
To My Dear Sister Jutta—
Some of the boys whisper that Dr. Hauptmann is connected to very powerful ministers. He won’t answer XXXXCENSOR MARKS HEREXXXX. But he wants me to assist him all the time! I go to his workshop in the evenings and he sets me to work on circuits for a radio he is testing. Trigonometry too. He says to be as creative as I can; he says creativity fuels the Reich. He has this big upperclassman, they call him the Giant, stand over me with a stopwatch to test how fast I can calculate. Triangles triangles triangles. I probably do fifty calculations a night. They don’t tell me why. You would not believe the copper wire here; they have XXXXCENSOR MARKS HEREXXXX. Everyone gets out of the way when the Giant comes through.
Dr. Hauptmann says we can do anything, build anything. He says the führer has collected scientists to help him control the weather. He says the führer will develop a rocket that can reach Japan. He says the führer will build a city on the moon.
To My Dear Sister Jutta—
Today in field exercises the commandant told us about Reiner Schicker. He was a young corporal and his captain needed someone to go behind enemy lines to map their defenses. The captain asked for volunteers and Reiner Schicker was the only one who stood up. But the next day Reiner Schicker got caught. The very next day! The Poles captured him and tortured him with electricity. They gave him so much electricity that his brain liquefied, said the commandant, but before they did, Reiner Schicker said something amazing. He said, “I only
