Garth the reward set upon Grettir’s head; but the murderer was very ill spoken of in the land: first, because he had used sorcery, which was against the law; next, that he had acted a cowardly part in bearing arms against a half-dead man. A suit of outlawry was brought against him in the Thing; but seeing that it would go against him he escaped to Norway. In that country lived an elder half-brother of Grettir. who had heard of his fate and determined to avenge him; neither knew the other by sight. Angle, however, becoming uneasy, went to Micklegarth (Constantinople), whither he was followed by Thorstein Dromond. One day, at a weapon-showing, or exhibition of arms, Angle drew the short sword which had belonged to Grettir; it was praised by all as a good weapon, but the notch in the edge was a blemish. Angle related how he had slain Grettir, and how the notch came to be there. Thereupon Thorstein, who was present, knew his man, and asked to be allowed, like the rest, to see the short sword; Angle gave it to him, whereupon Thorstein clove his head in two with it, and Angle fell to earth dead and dishonoured.
Thus Grettir was avenged.
