Then they departed, but returned daily to him. Werbode stealthily spied their ways and doings, and told their father that they had become Christians, and were then worshipping in Chad's oratory, adding that their conversion would alienate his subjects. The king set out in anger for the cell, the queen sending Werbode before to tell the princes of his approach, that they might hide. But Werbode only looked in at the window of the oratory, and saw them praying earnestly. He returned to the king, and told him that his sons were obstinate in their purpose of worshipping Christ. The king, pale with anger, rushed towards the oratory. He threatened them with his vengeance for breaking the laws of the land by becoming Christians, and bade them renounce Christ. Wulfade replied, "They did not want to break the laws, and that the king himself once professed the faith which now he renounced. They wished to retain his fatherly affection, but no tortures could turn them from Christ." The king rushed furiously upon him, and cut off his head. His brother, Rufine, fled, but his father pursued him, and gave him a mortal wound. Thus these two departed to celestial glory. Werbode was smitten with madness when they returned to the castle and told the murder in the ears of all. The queen buried her sons honourably in one stone tomb, and withdrew with her daughter, Werburga, to the monastery at Sheppey, and then to that of Ely. The king, overcome with remorse, fell dangerously ill. The queen counselled him to seek out Chad, and confess to him. Wulfere took her advice, and starting one morning with his thanes, as if to follow the chase, his attendants got scattered from him, and he was left alone. Soon he espied the meek hart with the rope round its neck; he followed its track gladly, till he came to Chad's cell. The king, approaching the oratory, espied the saint saying mass; he dared not enter till he had been shriven. When the canon began, so great a light shone through the apertures in the wall, that priest and sacrifice were covered with such splendour that the king was nearly blinded by it, for it was brighter than that of the natural sun.
