"I pledge you my word I will, Balthazzar. But what has this trembling blockhead told you?"

"Satanas! that Donna Olivia, to whom not an hour ago I plighted my love and troth, has even now a cavalier in her chamber."

"Impossible; he lies!"

"He does not—I know that he does not. I have bribed him to watch his mistress, and have long found him faithful. But Olivia, false and base Olivia! I have long suspected her falsehood and coquetry, and this night I will fearfully revenge them both upon herself. It must be Carlos Avallo. Malediction! I will slay him before her face. By our Lady of the Rock! my most sacred oath, I swear it!"

Balthazzar rushed away from the chapel, and Stuart followed to prevent him, if possible, from committing any outrage, and pursued him through the dark streets at his utmost speed. In a few seconds they stood before the mansion they had quitted but a short time ago. It was completely involved in darkness, save one room, from the windows of which a light straggled through the white curtains upon the balcony from which they had witnessed the bull-fight.

"The sisters sleep in separate apartments; that is Olivia's," whispered Truxillo, in a voice husky with the passions which possessed his heart. "Did you not see a tall shadow pass the window?"

"Let me entreat you, noble condé, to stay—to hold but for a single moment!"

"Carajo! may it be my last if I do!" replied the other fiercely, as he grasped a carved stone ornament projecting from the wall, and swung himself into the balcony, where he drew his sword, and applied his eye to the opening of the window curtains. Apprehensive that he might commit some rash deed, Ronald followed him, but with infinite trouble, rage having enabled the condé to climb by means which the other could not find. He was not without some secret fears that this rival cavalier might be Louis Lisle, and grasping Truxillo by the arm, he detained him by main force; and had the parties within been less occupied with themselves than they were, they must undoubtedly have heard the half-muttered threats of Balthazzar, and the scuffling which ensued on the balcony.

Through the half-opened casement they surveyed the chamber and its occupants. The sleeping-place of the donna was certainly a splendid one; the hangings, the chairs, the bed, and covering of the estrado, raised at one end of the floor, were all of white or rose-coloured velvet, fringed and embroidered with gold, and every thing else was of corresponding richness. A lamp, the globe of which was of rose-coloured glass, shed a warm light through the apartment; and three large vases of fresh flowers, placed on the verge of the estrado, gave forth an agreeable perfume. In a splendid easy-chair, which glittered with gilding and gilt nails, the beautiful Olivia was seated near her toilet-table,—the looseness of her dress and the disorder of her ringlets showing that she had been preparing for repose before her visitor had entered by the window, a place of ingress used oftener than the door by Spanish lovers. An officer in a Spanish cavalry uniform was kneeling at her feet, and his cloak and helmet lay on the floor near him.

"Lo! holy Virgin, a pretty piece of daring," said the lady as they approached the window.
