The marker squeaks going on. 4408, 4409, 4410, 4411, 4412, stacked down the inside of Lesia Hrytsenko’s left forearm, high enough for a sleeve to cover and low enough that she can read them by turning her wrist.
The complex dried grain here for forty years and has not stopped smelling like it. Wet dust in the pits, something sweet and turning in the corners where the augers used to run. Over that the shop lays down its new weather: burnt motor windings, hot resin off the wash tanks, the printer farm on the old sorting floor running all night, thirty-odd machines building drone frames layer by layer with a sound like insects working a field.
Five autumns now the yard has dried something other than grain.
The five in the crate carry her revision. She moved a few grams forward out of the tail, changed how hard the thing is allowed to want the turn once it finally sees, and rebuilt the seeker mount so a boy with cold hands can seat it in the dark. The changes went into the notebook for the engineers in Kyiv. The serials went on her arm, which is hers.
Danylo Svystun backs the Toyota to the loading lip at four in the morning with the engine running and a cigarette behind his ear. It has been behind his ear since Tuesday. He does not light it inside the fence, on account of the resin, the fuel, and the thirty printers.
“Five,” he says.
“Five.” She sets the crate in herself and slides it to the cab end. Twenty kilometers short of the line there is a dugout with a folding table, two crews, and one strip of sky worth watching, and everything she has done this week goes there in the bed of a dishwater-colored pickup with three hundred eighty thousand on the clock.
“Road past the Vorskla is soft because of the rain,” he says. “I will be slow.”
“Be slow.”
He pulls out with the lights off, the yard behind him lit by what spills from the doorway.
She works the night. Two hulls out of the wash, a tray of mounts, a motor that dies on the bench at eleven and fills the room with the smell of its own windings. Twice she turns her wrist to read what is written there, a habit she would deny under oath.
The Toyota comes back at ten in the morning with the passenger side of the bed burned black in a fan shape, the paint gone, the metal blued and puckered where the it took the heat and kept it.
Danylo gets out and stands with his hand on the mirror a while. Then he takes the cigarette from behind his ear and lights it in the doorway with the printers going behind him, and nobody says one word to him about the resin.
“Numbers,” Lesia says.
He holds up three fingers. “Three. The first three out of five.”
Sixty percent. She says a word her mother would have slapped her for, and he agrees with it, and for a moment the two of them stand in the dust and agree with it together. Thirty-four days they had been over eighty. A month of scrubbing her arm clean every morning like a woman washing up after a good harvest.
“Tell me.”
“Jet.” He pulls on the cigarette. His hand is unsteady and he does not pretend otherwise. “You hear it late. It is a whistle, and by the time you have the whistle it is already past you. And it turns.” He draws the turn in the air, a hard S. “It turns like it decided to. Yura put two up on it and both went stupid a kilometer out, wandering around. It carries its own jamming now. It sings to them the whole way in. Same thing both times.” He looks at the bed, at the fan of burnt paint, the shape of a thing that missed. “Then a third came down the road behind me at Trostyanets and I went in the ditch.”
Lesia goes to the bench and takes down the alcohol and a blue rag. 4408 comes off. Then 4409. Then 4410. The ink lifts gray into the cloth and leaves the skin pink under it for an hour after.
She stops at 4411 with the rag already wet. The rule was built for her own mistakes, for cold solder and a mount seated crooked and every stupid thing her hands have done at three in the morning. She has to decide whether it covers a thing that was never hers.
She caps the bottle.
Two numbers stay, dark, feathered a little at the edges from the alcohol. Left alone they go pale over a week and then they are gone, which is a different arithmetic, and she has never liked it. On the bench the next hull sits tacky from the wash. The tray beside it holds five mounts built for cold hands.
She pulls the stool in, turns her wrist, reads 4412, and starts.
