While lodging at the home of Gisli and Auda, Vestein is discovered stabbed to death by a spear. The saga states that the custom obligated the person who extracted the murder weapon to carry out vengeance, and Gisli takes the spear (Grásiða). No witness saw the murderer, but Gisli has been haunted by dreams for several nights, and is convinced he knows the murderer. Gisli will later kill Thorgrim, but there are some psychological developments in the wake of Vestein's death.
