"With your permission, I present my comrade, Señor Castillo," said Don Martin. "Should any disaster overtake me, Señor Castillo, or another whom he appoints, will carry out our contract.

But there are difficulties; the house may be watched." Don Martin looked thoughtful, but not disturbed; and Grahame saw that he could calmly take a risk. Danger and his host obviously were old acquaintances. "It is better that you go," he answered. "Sometimes I entertain an American traveler, and Englishmen now and then visit Rio Frio. I do not think you are suspected yet, and you may be able to help us by drawing off the watchers' attention when you leave. We will see what can be done, but it would be safer for Señor
