She found Good Samaritan the way the birds found the Platte. She spoke to the trauma doctor, working hard to follow him. He kept saying moderate severity, stable, and lucky. He looked young enough to have been out partying with Mark earlier that night. She wanted to ask to see his med school diploma. Instead she asked what “moderate severity” meant, and nodded politely at the opaque answer. She asked about “lucky,” and the trauma doctor explained: “Lucky to be alive.”
 
Firemen had cut him out of his cab with an acetylene torch. He might have lain there all night, coffined against the windshield, freezing and bleeding to death, just off the shoulder of the country road, except for the anonymous call from a gas station on the edge of town.
 
They let her into the unit to see him. A nurse tried to prepare her, but Karin heard nothing. She stood in front of a nest of cables and monitors. On the bed lay a lump of white wrapping. A face cradled inside the tangle of tubes, swollen and rainbowed, coated in abrasions. His bloody lips and cheeks were flecked with embedded gravel. The matted hair gave way to a patch of bare skull sprouting wires. The forehead had been pressed to a hot grill. In a flimsy robin’s-egg gown, her brother struggled to inhale.
 
She heard herself call him, from a distance. “Mark?” The eyes opened at the sound, like the hard plastic eyes of her girlhood dolls. Nothing moved, not even his eyelids. Nothing, until his mouth pumped, without sound. She leaned down into the equipment. Air hissed through his lips, above the hum of the monitors. Wind through a field of ready wheat.
 
His face knew her. But nothing came out of his mouth except a trickle of saliva. His eyes pleaded, terrified. He needed something from her, life or death. “It’s okay; I’m here,” she said. But assurance only made him worse. She was exciting him, exactly what the nurses had forbidden. She looked away, anywhere but at his animal eyes. The room burned into her memory: the drawn curtain, the two racks of threatening electronic equipment, the lime sherbet–colored wall, the rolling table alongside his bed.
 
She tried again. “Markie, it’s Karin. You’re going to be all right.” Saying it made a kind of truth. A groan escaped his sealed mouth. His hand, stuck with an IV tube, reached up and grabbed her wrist. His aim stunned her. The grip was feeble but deadly, drawing her down into the mesh of tubes. His fingers feathered at her, frantic, as if, in this split second, she might still keep his truck from wiping out.
 
The nurse made her leave. Karin Schluter sat in the trauma waiting room, a glass terrarium at the end of a long corridor smelling of antiseptics, dread, and ancient health magazines. Rows of head-bowed farmers and their wives, in dark sweatshirts and overalls, sat in the squared-off, padded apricot chairs alongside her. She figured them: Father heart attack; husband hunting accident; child overdose. Off in the corner, a muted television beamed images of a mountain wasteland scattered with guerrillas. Afghanistan, winter, 2002. After a while, she noticed a thread of blood wicking down her right index finger, where she’d bitten through her cuticle. She found herself rising and drifting to the restroom, where she vomited.
 
Later, she ate, something warm and sticky from the hospital cafeteria. At one point, she stood in one of those half-finished stairwells of poured concrete meant to be seen only when the building was on fire, calling back to Sioux City, the massive computer and home electronics company where she worked in consumer relations. She stood smoothing her rumpled bouclé skirt as if her supervisor could see her over the line. She told her boss, as vaguely as she could, about the accident. A remarkably level account: thirty years of practice hiding Schluter truths. She asked for two days off. He offered her three. She started to protest, but switched at once to grateful acceptance.
