Chapter 1
Sofia
The first cow is dead before I get the treatment trailer backed to the temporary pens. The second is still breathing, but each pull of air lifts her whole rib cage off the dirt.
A third lies dead beside a black nurse tank. Twenty-one more crowd the fence around it, shoulder to shoulder despite the open pasture behind them. Six are down. The ones still standing have their heads low and their legs planted wide, as if the ground has developed opinions.
I set the brake, grab my field bag, and step into wet predawn air that smells of manure, diesel, and something sharp enough to raise the hair on my arms.
“Kill that valve,” I tell the driver.
Luis Ortega stares at me across the hood of his semi. He’s maybe fifty, gray threaded through his beard, both hands shoved into his ball cap hard enough to bend the bill. “The water?”
“Now. And don’t run them.”
He moves. Good.
The portable pens sit in a receiving pasture miles from the Barbed Crown headquarters. Temporary panels, a loading alley, two stock trailers, and a hand-painted sign wired to the gate: BIOSECURITY HOLD. RESPIRATORY EXPOSURE. The paint is new. The rusted wire holding it isn’t.
I duck through the rails and crouch beside the nearest cow. Black baldy, mature, probably bred. Her ear tag reads 14C. Her breathing is fast and shallow, and fine tremors run through her shoulder. When I lift her lip, her gums are a muddy gray-brown instead of pink.
“How long since you watered them?”
“Forty minutes. Maybe fifty.” Luis closes the valve and braces both hands on his knees. “They came off the trailer thirsty. I filled the tank from the ranch hydrant like the note said. First one fell ten minutes later. Then another. I called the number on the certificate.”
The trouble with being a mobile large-animal vet is that emergencies know where you sleep. The larger trouble is that this isn’t my client, my shipment, or my certificate. My phone number is the only part of this that belongs to me.
Headlights sweep across the pens.
Three ranch trucks arrive in a line. Men are out before the dust settles, but only one comes straight to the gate. He’s broad through the shoulders, in a dark work shirt with the sleeves rolled twice and an old ring of keys hanging from his belt. He looks at the cattle first, the open lane second, and me third.
That order earns him more goodwill than his face does, which is inconvenient, because his face earns plenty.
“Who are you?” he asks.
His voice is quiet. Not uncertain. Quiet the way men get when they’re used to being heard the first time.
“Dr. Sofia Rios. Who has authority over these pens?”
“I do.” He doesn’t look away from me when he points at the two men behind him. “Nate, shut the south gate and block the tank. Hector, bring panels. Walk. Nobody pushes them.”
Both men move. The standing cattle stop bunching almost immediately.
He steps through the gate. “Cole Barrett. Barbed Crown operations. What happened?”
“Probably poisoning. Nitrate is high on my list, but I haven’t ruled anything out. They need quiet handling, a clean water source, and treatment now.”
“Can we move them to the main ranch?”
“No. Their blood may not be carrying enough oxygen. Running them or hauling them could kill the ones still standing.”
His eyes come back to mine. Brown, steady, and not the least bit offended by a woman who knows more than he does about the problem in front of him.
“They stay,” he says. “Tell me what you need.”
I tell him while I work. Shade cloth on the west side. Fresh water from a different source in clean tubs. Nobody touches the black tank. Nobody removes a tag, a paper, a dead animal, or anything else from this pen.
He repeats it to his crew once, shorter but accurate, and men spread out without a single raised voice.
