Frank Bennett hadn't hidden the system merely to preserve a garden.
And the old spring wasn't the only secret beneath those six rows.
The most important discovery was still waiting inside a sealed metal box that three generations of farmers had unknowingly walked past.
A box containing a map, a handwritten agreement, and a name that would explain why Dale Harker had been pressuring Noah's mother to sell the farm.
Noah Bennett had lived his entire life on the property everyone in Ash Creek called Bennett's Hollow.
The name came from the shallow valley cutting through the northern portion of the farm. In wet years, the valley collected rainwater and carried it toward a seasonal creek. In dry years, it became a strip of dusty grass bordered by cottonwoods, hedgerows, and old fieldstone walls.
The farmhouse stood on a gentle rise overlooking the lower fields.
It wasn't beautiful in the way expensive country houses appeared in magazines. Its paint was peeling, one porch step needed replacing, and the kitchen floor creaked whenever someone walked toward the refrigerator.
But it was home.
Noah knew the sounds of the place.
The screen door that slammed when the wind came from the south.
The old refrigerator that hummed louder before its compressor stopped.
The barn roof that clicked as it warmed in the morning sun.
And the familiar scrape of his grandfather's boots against the porch boards.
Until the boots stopped coming.
Frank Bennett had been seventy-six when he died.
He was a tall, broad-handed man with white hair, deep wrinkles, and the kind of patience people rarely noticed until they needed it. He had spent most of his adult life growing wheat, sorghum, vegetables, and small specialty crops on land that had belonged to his family since the early twentieth century.
Frank wasn't wealthy.
He owned equipment that was older than some of the men who repaired it.
