He came forward into the light now. In his hand he held a paper which he was unfolding. Juanita recognised the letter she had written to him in the drawing-room at Torre Garda. He tore the blank sheet off and folding the letter closely, replaced it in his pocket. Then he laid the blank sheet on the dusty splash-board of the carriage and wrote a few words in pencil.

"You must get back to Pampeluna," he said to the driver in that tone of command which is the only survival of feudal days now left in Europe--and even the modern Spaniards are losing it--"at any cost--you understand. If you meet the reinforcements on the road give this note to the commanding officer. Take no denial; give it into his own hand. If you meet no troops go straight to the house of the commandant at Pampeluna and give the letter to him. You will see that it is done," he said in a lower voice, turning to Sor Teresa.

The man protested that nothing short of death would prevent his carrying out the instructions.

"It will be worth your while," said Marcos. "It will be remembered afterwards."

The quiet voice of Sor Teresa broke the silence, softly taking its place in his thoughts. It seemed that the Sarrion brain had the power--the secret of so much success in this world--of thrusting forth a sure and steady hand to grasp the heart of a question and tear it from the tangle of side-issues among which the majority of men and women are condemned to flounder.

"Where is Evasio Mon?" she asked.

Marcos answered with a low, contented laugh.

"He is trapped in the valley," he said in French. "I have seen to that."

The firing had ceased as suddenly as it had commenced, and a silence only broken by the voice of the river, now hung over the valley.
