As the rider pulled up he came within the rays of the lamp which was a powerful one; and at the sight of him Juanita gave a sharp cry which neither she nor any that heard it forgot to the end of their lives.

"It is Marcos," she cried, clutching Sor Teresa's arm. "And he came through that--he came through that!"

"No one hurt?" asked Marcos' deep voice.

"No one hurt, Señor," answered the driver who had recognised him.

"And the horses?"

"The horses are safe. A malediction upon them; they nearly had us over the cliff. Those are the troops. They took us for Carlists."

"No," said Marcos. "They are the Carlists. The troops have been driven farther up the valley where they are entrenched. They have sent to Pampeluna for help. This is a Carlist trap to catch the reinforcements as they approach. They thought your carriage was a gun."

The driver scratched his head and made known his views as to the ancestory of the Carlists.

"There is no getting into the valley to-night," said Marcos to Sor Teresa and Juanita. "You must return to Pampeluna."

"And what will you do?" asked Juanita in a hard voice.
