“Yes, and a big part,” declared Donald. “If we could locate that door, we could find Don Rafael. Don’t you think so, Billie?”
“I’m sure of it.”
“Then let’s find it!”
“I’ll show it to you,” said a soft voice, which came to them out of the semi-darkness.
At the sound of the voice the boys turned hastily and grasped their weapons.
“Don’t be afraid,” continued the voice. “No one is going to hurt you,” and out of the darkness stepped Santiago.
“I just said you were the greatest mystery,” exclaimed Billie, as soon as he saw who the newcomer was, “and now I know it.”
“Not a mystery,” declared Santiago, “but a patriot.”
“Which is even a greater curiosity in Mexico,” declared Donald.
“I am afraid you are right,” was the sad reply; “but there are still a few, and some day we will free Mexico from the rule of those who seek nothing but their own advancement.”
