Teresa could not lie; her sincerity conquered her natural timidity.

"Pardon me, brother," she answered, "but I shall never bestow my hand on the son of the Count of Cabra."

"May the anger of God strike you! What is that you dare to say, traitress? Do you repay my affection by opposing yourself insolently and rebelliously to my will? Teresa, you shall be the wife of Nuño Garciez!"

"Have compassion on me, my brother; do not condemn to eternal sadness, to eternal pain, to eternal despair this heart which has suffered so much."

And the Infanta sank down on her knees before her brother, bursting into tears.

"Have you any for me, perchance?" retorted Don Suero. "Have you compassion for me when, seeing me surrounded by enemies, you refuse to procure for me the aid of a family which could help me to triumph over all my rivals?"

"But I could never love Nuño Garciez, and my vow before the altar would be horrible perjury. Brother, have pity on me; remember the promise you made to our mother; remember that she, who gave you life, blessed you when she was breathing her last; for you had just promised her that you would be my shield, my protector, my brother—not my executioner"—

"Hell, hell! Arise from your knees, traitress, for your supplications and tears are unavailing!" roared Don Suero, at the very height of his rage.

And with a violent push he threw the gentle girl on the floor.
