"Defend yourself, Don Lope," exclaimed he, with frenzied rage.

"Look to yourself, fair Sir," returned Don Lope, as, unsheathing his rapier, he calmly placed himself in a posture of defence.

With impetuous fury Don Rodrigo darted on his antagonist, and commenced an assault with all the courage and address of a practised swordsman. Thrust succeeded thrust with mortal rapidity, but the active eye of Gomez Arias foiled their deadly aim with consummate skill and dexterity. A demoniac spirit seemed to agitate Don Rodrigo, and he continued for some minutes wasting his strength in the fruitless attack, and impairing his own means of resistance. The combat was too fierce to be of long duration, and a few moments would have brought it to a mortal issue (for Don Lope was now in his turn about to press hard his weakened adversary), had not Roque, in that tenderness of conscience for which he was so noted, very adroitly extinguished the light that hung in the Zaguan, as the most effectual way of suspending hostilities.

The place was thus plunged in utter darkness, and Don Rodrigo, afraid of being disappointed in his revenge, called out to Gomez Arias.

"I am here," replied Don Lope; "I am here, Don Rodrigo; the light is superfluous; we shall do perfectly well without it, for a mutual sympathy will lead our weapons aright."

The swords again met, and short, quick sparks of light, like the fugitive flash of a summer's exhalation, gave a momentary glimpse of the combatants' fearful countenances—then a dismal groan is heard, a body falls heavily on the ground, and a shriek of horror burst from the household, who had crowded round the entrance of the Zaguan.

"He is dead," muttered Don Rodrigo to himself, and sought for safety with the swiftness of lightning.

"Bring torches," cried Monteblanco; "let us afford the fallen caballero all the assistance in our power."

The state of Theodora baffles all description. Ignorant as yet who was the victim, her soul was harrowed up with the most fearful apprehensions, the reality of which would dash the cup of happiness from her lips, and embitter her future existence. This petrifying, this heart-rending suspense was happily but of short continuance. Theodora herself, with breathless anxiety, was the first to bring a torch, that might perhaps illume the pale ghastly features of him on whom she had centered all her felicity. The moment was awful, when the torch throwing a broad glare around the Zaguan, discovered Gomez Arias, tranquil and erect, in all the assurance of perfect safety. A faint scream escaped from the bosom of his mistress, for all the feelings which horrifying suspense had held imprisoned there, now sought relief in a tumult of sighs and tears. Her emotion, however, was scarcely noticed by her father, too much occupied at the time in ascertaining which was the fallen cavalier.

"Don Rodrigo is then the victim," sorrowfully exclaimed the old cavalier, casting his eyes around; for at this moment he spied a human body, lying in a dark corner of the Zaguan.
