"Which side does he belong to?" asked Adrian. "Huerta or Carranza?"
"Neither. He is simply a bandit, and his followers prey upon any whom they find unprotected."
"And do you really think they are going to hold up and rob the train from Pachuca?"
"Sin duda!" meaning without doubt.
"Then we must prevent them," declared Donald emphatically.
"What business is it of ours?" asked Billie. "If one bunch of Mexicans wants to rob another bunch, especially if the second bunch are Huertistas, I don't know that it is for us to interfere. I'm not looking for trouble."
"You're not afraid, are you? If——"
"Say, Don," interrupted Billie, "what's the use of always asking such foolish questions? If I remember rightly, the last time you asked me that question was up on the Rio Grande a year ago, about the time that I was swimming rivers and breaking into prisons with the Texas Rangers to get you and Ad out of trouble. Now why——"
Donald held up both hands.
"That's enough, Billie," he laughed. "I'll take it all back. Of course you're not afraid. But I insist we must prevent this hold-up."
