"Thou wilt thyself prove thyself, what thou art," said Grettir, and
therewith he put off his clothes and weapons, and swam off for the
nets. He swept them up together, and brought them to land, and cast
them on to the bank; but when he was minded to come aland, then Thorir
caught up the short-sword and drew it hastily, and ran therewith
swiftly on Grettir, and smote at him as he set foot on the bank; but
Grettir fell on his back down into the water, and sank like a stone;
and Thorir stood gazing out on to the water, to keep him off from
the shore if he came up again; but Grettir dived and groped along the
bottom as near as he might to the bank, so that Thorir might not see
him till he came into the creek at his back, and got aland; and Thorir
heeded him not, and felt nought till Grettir heaved him up over his
head, and cast him down so hard that the short-sword flew out of his
hand; then Grettir got hold of it and had no words with him, but smote
off his head straightway, and this was the end of his life.
But after this would Grettir never take outlaws to him, yet hardly
might he bear to be alone.
