Sophie’s father, Daniel, unlocked the trailer.
Anvil stopped him before he stepped inside.
“False floor first.”
Daniel stared at him.
“You really knew my dad?”
“Long enough to know he never trusted locks.”
The veterinarian stayed with Sophie’s horse while two deputies cleared the livestock aisle.
Daniel removed the rubber matting from the trailer floor.
Nothing.
Then Anvil pointed to one steel bolt near the rear wall.
It was newer than the others.
Daniel turned it.
A narrow panel lifted.
Inside was a waterproof metal box wrapped in an old saddle blanket.
Sophie crouched beside her father.
“What is it?”
Daniel opened the box.
There were veterinary reports.
Photographs.
Feed invoices.
And a leather notebook bearing Frank Bennett’s initials.
Daniel’s expression changed.
“My father kept records of everything.”
Anvil nodded.
“That’s why somebody wanted this trailer.”
For years, Frank had supplied horses to regional rodeos and youth programs across Texas.
Six months before his death, several animals became violently ill after competitions.
The official explanation was contaminated feed.
Frank disagreed.
He collected samples from water stations at three different fairgrounds.
Each contained traces of the same sedative.
Not enough to kill a horse.
Enough to weaken one before competition.
Sophie looked toward her collapsed gelding.
“Someone drugged him?”
The veterinarian examined the oily residue.
“It’s possible.”
Daniel flipped through Frank’s notebook.
One name appeared repeatedly.
Calvin Ross.
A livestock contractor who supplied temporary stalls, water tanks and transport equipment to county events.
Daniel knew him.
Everyone did.
Ross’s company had supplied the water system outside the arena that morning.
Anvil removed a folded letter from the metal box.
Frank had addressed it to him.
Wade—
If Calvin is still working fairs when Sophie starts competing, don’t confront him without proof.
Daniel looked up sharply.
“Why would Dad write to you instead of me?”
Anvil’s jaw tightened.
“Because you hated motorcycles.”
Daniel blinked.
Despite everything, Sophie almost laughed.
Anvil did not.
Frank and Anvil had ridden together before Daniel was born.
When Frank discovered the contaminated water, he asked Anvil to help move samples between events without using company vehicles.
Then Frank died of a heart attack before he could take the evidence to investigators.
Anvil promised to watch the family from a distance.
“That photograph was your warning?” Daniel asked.
“No.”
Anvil pointed toward the trailer.
“Seeing this trailer here was.”
One deputy returned from the water station.
The main tank had been cleaned less than an hour earlier.
Someone had replaced the hose.
Security footage showed a man in a contractor shirt entering Sophie’s stall before sunrise.
The image was blurry.
But Daniel recognized the silver belt buckle.
Calvin Ross.
Then the veterinarian called from the paddock.
Sophie’s horse was recovering.
The dose had been low.
“He should be okay.”
Sophie cried against her father’s shoulder.
Daniel looked back at Frank’s notebook.
A final page had been folded inward.
Inside was a photograph of Ross standing beside another man at a water tank.
The second man wore a county-fair identification badge.
Daniel stared at him.
“That’s impossible.”
Anvil took the photograph.
The man was Robert Bennett.
Daniel’s older brother.
Sophie’s uncle.
Robert had disappeared eight years earlier.
The family believed he had died after his truck was found abandoned near the Canadian River.
Anvil turned the photograph over.
Frank had written a date.
Three months after Robert supposedly disappeared.
And beneath it:
ROBERT KNOWS WHO STARTED THIS.
