Greatly astounded as Villafana was by this unexpected defection, the shock served rather to sober than affright him. He gave the prisoner a look of unspeakable malice, and whipping out his sword and calling for help as clamorously as Juan, he assaulted him with the utmost fury. At the same time, five or six of the guardsmen rushed in, and to Juan's utter dismay, instead of aiding him to secure the Alguazil, rushed upon him, some with their spears, to transfix him against the wall, while others, springing behind him, secured him in their arms, and hurled him upon the floor. In an instant, he had lost both the fatal list and the dagger of Guatimozin, and was at the mercy of Villafana, who knelt upon his breast, and shortened his sword, to despatch him with a thrust. But at the very moment when he had given up all hope, and was commending his soul to his Maker, the savage and exulting laugh with which the Alguazil aimed at his throat, was changed to an exclamation of alarm and pain. Up started the assassin, and Juan, springing also to his feet, he beheld, with surprise, the figure of La Monjonaza standing betwixt him and the assailants. The gray mantle had fallen from her head and shoulders, revealing a form of the finest symmetry, and a countenance convulsed into beauty, such as might have become a warring Bellona; to whom she might have been well compared, only that in place of the whip and torch which a moralizing mythology has put into the hands of the goddess, she held an emblem equally expressive, in a short dagger, gleaming with blood from the shoulder of Villafana. "Villain!" she cried, after looking as if she would have repeated the blow, "art thou not yet requited? Begone!" And the discomfited traitor, scowling and pointing at the blood trickling from his arm, and yet obviously quailing before her stern frown, left the prison, followed by the guards, who seemed even more terrified than himself. CHAPTER XIX. Juan stood, for a moment, confounded in the presence of his preserver; and Magdalena, gradually exchanging her fierce expression for one more becoming her sex, appeared at last, as he had seen her before, pale, saddened, and subdued. As she sank into this softened temper, her eye fell upon the crimsoned blade; and it was curious to see with what feminine horror, disgust, and shame, she cast it from her, and to contrast this display of undissembled feelings with her late Amazonian bearing and act.
