The Book of Dreams and Ghosts

"Glam wanted to get him outside, and although Grettir set his feet against everything that he could, yet Glam succeeded in dragging him out into the porch. There they had a fierce struggle, for the thrall meant to have him out of doors, while Grettir saw that bad as it was to deal with Glam inside the house it would be worse outside, and therefore strove with all his might against being carried out. When they came into the porch Glam put forth all his strength, and pulled Grettir close to him. When Grettir saw that he could not stay himself he suddenly changed his plan, and threw himself as hard as he could against the monster's breast, setting both his feet against an earth- fast stone that lay in the doorway. Glam was not prepared for this, being then in the act of pulling Grettir towards him, so he fell backwards and went crashing out through the door, his shoulders catching the lintel as he fell. The roof of the porch was wrenched in two, both rafters and frozen thatch, and backwards out of the house went Glam, with Grettir above him. "Outside there was bright moonshine and broken clouds, which sometimes drifted over the moon and sometimes left it clear. At the moment when Glam fell the cloud passed off the moon, and he cast up his eyes sharply towards it; and Grettir himself said that this was the only sight he ever saw that terrified him. Then Grettir grew so helpless, both by reason of his weariness and at seeing Glam roll his eyes so horribly, that he was unable to draw his dagger, and lay well-nigh between life and death.
