The daughter finds favor in the victor’s eye, and they marry; but the old man’s animosity toward his conqueror is not lessened and he plans to kill the king in spite of the fact that he has become the daughter’s husband. She learns of the plot and not wishing to betray her father nor to have her husband meet death she disguises herself in the kingly robes of her spouse. Wearing his crown, carrying his sword and imitating his footsteps, she passes along the corridor in which she knows the conspirators are hidden and receives the fatal blow intended for the victorious ruler.
