Griffin Tucker had survived drought, blizzards, cattle disease, and the crushing humiliation of owing money to Harrison Caldwell.

But nothing prepared him for discovering that the woman sleeping beneath his roof was apparently the most wanted businesswoman in three states.

He held the newspaper with trembling hands.

“TWO MILLION DOLLARS MISSING.”

The words seemed to leap from the page.

Below them was Mattie’s face.

Not the tired woman who fed his hens each morning.

Not the stubborn bride who had stood between him and an armed banker.

A younger, richly dressed woman standing outside a magnificent stone building in Philadelphia.

“Margaret Ashford,” Griffin read aloud.

Mattie said nothing.

“Is that your name?”

“Yes.”

“Are you a thief?”

“No.”

“Then explain why every newspaper in the East says you are!”

Mattie lowered herself into the kitchen chair.

For the first time since stepping off the train, she looked truly weary.

“Because the people who stole the money owned the newspapers that accused me.”

Griffin stared.

Mattie opened the velvet ledger.

“My father built Ashford Agricultural Exchange. We financed grain shipments, irrigation projects, mills, and farms across six states. When he passed away, I inherited controlling ownership.”

Griffin slowly sat down.

“You owned a bank?”

“Not a bank. Something considerably more useful to farmers.”

She turned a page.

“Three years ago, I discovered that my managing partners had been selling fraudulent agricultural loans. Thousands of families were paying debts they did not legally owe.”

Griffin thought of Caldwell.

“The same thing happening here?”

“Precisely.”

“Then why didn’t you expose them?”

“I tried.”

Mattie’s voice became quiet.

“My evidence disappeared. My closest adviser betrayed me. Then someone forged my signature on the largest transfer in company history.”

“Two million dollars.”

She nodded.

“The authorities came for me before I could prove what happened.”

Griffin leaned back.

“So you fled.”

“I followed the money.”

She pushed a sheet of calculations across the table.

Griffin recognized one name immediately.

Harrison Caldwell.

His stomach tightened.

“Caldwell was involved?”

Mattie looked directly at him.

“Griffin, Caldwell wasn’t merely involved. He was the man receiving the stolen money.”

Outside, the wind rattled the shutters.

“Why come to my ranch?”

Mattie hesitated.

“Because your father’s name appeared in the original records.”

Griffin stood so abruptly his chair toppled.

“My father was an honest man.”

“I know.”

“You never met him!”

“No,” she said. “But he was the first person who tried to stop Caldwell.”

Griffin stared at her.

Mattie removed a fragile letter from the ledger.

On its front was a familiar signature.

Thomas Tucker.

His father’s handwriting.

Griffin opened it.

The letter described fraudulent mortgages, stolen livestock payments, and an agreement between Caldwell and several Eastern financiers.

Its final sentence made Griffin’s blood run cold.

“If anything happens to me, the proof is buried where the old river once ran.”

Griffin read it three times.

Then he looked up.

“My father died trying to cross Bitter Creek during a storm.”

Mattie nodded slowly.

“That’s what the official report said.”

For a long moment, neither spoke.

Then Griffin whispered, “You think someone caused his death?”

“I know he discovered something Caldwell desperately wanted hidden. I don’t know exactly what happened afterward.”

The next morning, Griffin and Mattie rode to the old creek bed.

The land was cracked and nearly lifeless.

Mattie climbed down from the wagon and examined the terrain.

“Your father mentioned the old river,” she said. “Not the present creek.”

Griffin pointed toward an abandoned cottonwood grove.

“The river changed course forty years ago.”

They searched until afternoon.

Then Mattie spotted a line of unusually smooth stones half-buried beneath the soil.

“Griffin. Bring the shovel.”

Two hours later, the metal blade struck wood.

Together they unearthed a narrow ironbound chest.

Inside were land surveys, original deeds, and a thick packet of correspondence wrapped in oilcloth.

There was also a small brass key.

Griffin lifted the first survey.

“What is all this?”

Mattie studied the papers.

Then her eyes widened.

“Good heavens.”

“What?”

“This ranch doesn’t sit on worthless land.”

She spread the survey across the ground.

Beneath the Broken Spur lay a vast underground water source.

Enough, according to the original report, to supply an entire agricultural settlement.

Caldwell had known.

That was why he had driven the ranch into debt.

That was why he wanted the deed.

And that was why he had arrived with armed men.

Griffin stared toward his parched fields.

“All this time…”

Mattie touched his shoulder.

“Your father protected something extraordinary.”

Suddenly, a rifle shot shattered the quiet.

The shovel jumped from Griffin’s hand.

Another shot struck the wagon wheel.

“DOWN!” Griffin shouted.

They threw themselves behind a boulder.

Three riders appeared along the ridge.

Caldwell’s men.

Griffin returned fire, forcing the riders to seek cover.

But the attackers began circling toward the only path out.

“We’re trapped,” he whispered.

Mattie examined the ironbound chest.

Then she looked toward the old river channel.

“No,” she said. “We have another way.”

She pointed toward a narrow opening hidden beneath tangled roots.

Griffin remembered exploring that hollow as a boy.

An abandoned drainage tunnel.

They crawled inside, dragging the chest between them.

Dust filled their lungs.

Behind them, the gunmen approached.

One voice shouted, “Find the woman! Caldwell wants her alive!”

The tunnel sloped downward.

Water suddenly appeared beneath their boots.

Then more water.

Griffin froze.

“Mattie…”

The ground began to tremble.

Far below them, something enormous shifted.

With a deafening crack, the old stone barrier beneath the creek collapsed.

A torrent of underground water burst through the passage.

Griffin grabbed Mattie around the waist.

They barely reached a narrow ledge before the flood thundered past.

The chest vanished into the current.

Griffin watched helplessly.

“All the evidence!”

Mattie clung to the rock, breathing hard.

“Not all of it.”

She opened her coat.

The velvet ledger was still tucked securely against her chest.

Then Griffin noticed something else.

The brass key hung from a chain around her neck.

“What’s that for?”

Mattie’s expression changed.

“Something your father left in a place Caldwell would never think to search.”

“Where?”

She looked at him.

“Under the floor of your kitchen.”

And above them, the gunmen had discovered the tunnel entrance.
