The need for Angela Vicario to be a virgin and the social importance placed on virginity are what motivate Angela's brothers to slay the innocent Santiago Nasar. Angela marries Bayardo San Román, though she is not in love with him, and her husband then finds out she is not a virgin and returns her to her mother's house. Her family is shamed by this situation, as Bayardo comes from a wealthy family and promises a better life for Angela. In addition, a woman's virginity is, according to the societal standards of that time and place, the gift she gives her husband, as he must be sure of the paternity of his children. Because she is not a virgin, Angela claims that she was raped by Santiago Nasar, whom her brothers kill. Her lie is an attempt to save face, as she hopes to regain her husband and her reputation. The need for brides to be virgins is what sets the entire calamitous set of events in the book in motion.
