“Somebody’s mighty foxy,” observed the man; “but I don’t see what it’s all about. The days of cattle runners and bandits are over.”

“Just imagine!” exclaimed the girl. “A real mystery in our lazy, old hills!”

The man rode in silence and in thought. A herd of pure-bred Herefords, whose value would have ransomed half the crowned heads remaining in Europe, grazed in the several pastures that ran far back into those hills; and back there somewhere that trail led, but for what purpose? No good purpose, he was sure, or it had not been so cleverly hidden.

As they came to the trail which they called the Camino Corto, where it commenced at the gate leading from the old goat corral, the man jerked his thumb toward the west along it.

“They must come and go this way,” he said.

“Perhaps they’re the ones mother and I have heard passing at night,” suggested the girl. “If they are, they come right through your property, below the house—not this way.”

He opened the gate from the saddle and they passed through, crossing the barranco, and stopping for a moment to look at the pigs and talk with the herdsman. Then they rode on toward the ranch house, a half mile farther down the widening cañon. It stood upon the summit of a low hill, the declining sun transforming its plastered walls, its cupolas, the sturdy arches of its arcades, into the semblance of a Moorish castle.

At the foot of the hill they dismounted at the saddle horse stable, tied their horses, and ascended the long flight of rough concrete steps toward the house. As they rounded the wild sumac bush at the summit, they were espied by those sitting in the patio, around three sides of which the house was built.

“Oh, here they are now!” exclaimed Mrs. Pennington. “We were so afraid that Grace would ride right on home, Custer. We had just persuaded Mrs. Evans to stay for dinner. Guy is coming, too.”

“Mother, you here, too?” cried the girl. “How nice and cool it is in here! It would save a lot of trouble if we brought our things, mother.”
