After a time Harald, the younger son, received the rule of the sea, and chose soldiers who were unmarried, fearing to be baffled like his brother.

Fortune favoured his choice; for he was as glorious a rover as his brother was inglorious; and this earned him his brother's hatred.

Moreover, their queens, Signe and Ulfhild, one of whom was the daughter of Siward, King of Sweden, the other of Karl, the governor of Gothland, were continually wrangling as to which was the nobler, and broke up the mutual fellowship of their husbands.

Hence Harald and Frode, when their common household was thus shattered, divided up the goods they held in common, and gave more heed to the wrangling altercations of the women than to the duties of brotherly affection.
Moreover, Frode, judging that his brother's glory was a disgrace to himself and brought him into contempt, ordered one of his household to put him to death secretly; for he saw that the man of whom he had the advantage in years was surpassing him in courage.

When the deed was done, he had the agent of his treachery privily slain, lest the accomplice should betray the crime.
