The men said wherever they came that Grettir had burnt those people; and the news soon spread that the victims were the sons of Thorir of Garth.
Grettir therefore now grew into such bad repute that he was driven from the ship, and scarcely any one would say a good word for him. As matters were so hopeless he determined to explain all to the King, and offer to free himself from the slander by handling hot iron without being burned.
His ill-luck still pursued him, for when all was ready in the Church where the ceremony was about to take place, a wild-looking lad, or, as some said, an unclean spirit, started up from no one knew where, and spoke such impertinent words to Grettir that he felled him with a blow of his fist.
After this the King would not allow the ceremony to go on: "Thou art far too luckless a man to abide with us, and if ever man has been cursed, of all men must thou have been," said he; and advised him to go back to Iceland in the summer.
Meanwhile Asmund the Greyhaired died, and was buried at Biarg, and Atli succeeded to his goods, but was soon afterwards basely murdered by a neighbouring chief, who bore him ill-will for his many friendships, and grudged him his possessions.
Thorir of Garth brought a suit at the Thing to have Grettir outlawed for the burning of his sons; but Skapti the Lawman thought it scarcely fair to condemn a man unheard, and spoke these wise words: "A tale is half told if one man tells it, for most folk are readiest to bring their stories to the worser side when there are two ways of telling them."
Thorir, however, was a man of might, and had powerful friends; these between them pushed on the suit, and with a high hand rather than according to law obtained their decree. Thus was Grettir outlawed for a deed of which he was innocent.
Next, Grettir's enemy Thorir of Garth heard of his whereabouts, and prevailed upon one Thorir Redbeard to attempt to slay him.
So Redbeard laid his plans, with the object, as it is quaintly phrased, of "winning" Grettir. He, however, declined to be "won," for Redbeard fared no better than Grim.
