"It flashed over us all at once that we had found the right man. Everything fitted too well together to permit of a mistake, and you can believe that we treated Porfirio, the vaquero, the finest we knew how, and made him feel that he had fallen into the hands of the best friends in the world. Were you still alive? We waited without drawing breath for the answer. You were still alive he answered, and well, so far as a prisoner could be. He knew that positively from his mother, Catarina, who was a cook at the castle, although he himself would not stay there, as, like a sensible man, he liked the mountains and the plains and the free life. He did not tell us of the blow that de Armijo had given you, perhaps because Catarina had said nothing of it to him, but we learned that he hated de Armijo, who had once struck him when he was at the castle, for some trifle or other--it seems that de Armijo had the striking habit--and after that we soon made our little plot. Catarina, of course, was the center of it, and her duties as a cook gave her the chance. "It was Catarina who put the thread in the tamale. She might have put the letter there, but the writing on it would have been effaced, and even if it could have remained she did not dare. If the paper had been discovered by the Mexicans, she, of course, would have been declared guilty, but thread, even a package of it, might have found its way into the loose Mexican cooking, and if it had been discovered none of the sentinels or officers could have made anything out of such a slender thing. We trusted to your shrewdness that you would drop the thread out of the window, because there was nothing else to do with it, and you didn’t fail us." "But who tied the note on it?" asked John. "Catarina, again--that is, she was at the end of the chain, Porfirio was in the middle, and we were at the other or far end. He passed the letter in to her--he works about the castle at times--and she tied it on the end of the thread. The key and the dagger reached you by the same route. Then we knew that, although you might unlock the door of your cell, you could never go outside the castle without the aid of some one within. For that reason we told you the night on which to unlock it, and the very hour, in order that the right man might be waiting for you at the head of the stairway. Bill Breakstone had to be that man, because he can speak Spanish and the Mexican dialects, and because, lucky for you, he’s been an actor; often to amuse others he has played parts like the one that he played last night in such deadly earnest.
