One of the principal chiefs in the Skagafjord was Thorbjorn, nicknamed "The Hook," a hard-hearted, ill-disposed fellow.  His father had married a second time, and there was no love lost between the step-mother and Thorbjorn.  It is said that one day as The Hook was sitting at draughts, she passed, and looking over his shoulder, noticed that he had made a foolish move, so she laughed; whereupon Thorbjorn retorted angrily.  She instantly snatched up a draught-man, and, laying it against his cheek-bone, pressed it into his eye, so that the ball started out of its socket.  He sprang up, with a curse, and dealt her such a blow, that she took to her bed and died of the injury...
