Now Glam gathered up his strength and knit Grettir towards him when they came to the outer door; but when Grettir saw that he might not set his feet against that, all of a sudden in one rush he drave his hardest against the thrall's breast, and spurned both feet against the half-sunken stone that stood in the threshold of the door; for this the thrall was not ready, for he had been tugging to draw Grettir to him, therefore he reeled aback and spun out against the door, so that his shoulders caught the upper door-case, and the roof burst asunder, both rafters and frozen thatch, and therewith he fell open-armed aback out of the house, and. Grettir over him.
Bright moonlight was there without, and the drift was broken, now drawn over the moon, now driven from off her; and, even as Glam fell, a cloud was driven from the moon, and Glam glared up against her. And Grettir himself says that by that sight only was he dismayed amidst all that he ever saw.
Then his soul sank within him so, from all these things, both from weariness, and because he had seen Glam turn his eyes so horribly, that he might not draw the short-sword, and lay well-nigh 'twixt home and hell.
But herein was there more fiendish craft in Glam than in most other ghosts, that he spake now in this wise--
"Exceeding eagerly hast thou wrought to meet me, Grettir, but no wonder will it be deemed, though thou gettest no good hap of me; and this must I tell thee, that thou now hast got half the strength and manhood, which was thy lot if thou hadst not met me: now I may not take from thee the strength which thou hast got before this; but that may I rule, that thou shalt never be mightier than now thou art; and nathless art thou mighty enow, and that shall many an one learn. Hitherto hast thou earned fame by thy deeds, but henceforth will wrongs and manslayings fall on thee, and the most part of thy doings will turn to thy woe and ill-hap; an outlaw shalt thou be made, and ever shall it be thy lot to dwell alone abroad; therefore this weird I lay on thee, ever in those days to see these eyes with thine eyes, and thou wilt find it hard to be alone--and that shall drag thee unto death."
Now when the thrall had thus said, the astonishment fell from Grettir that had lain on him, and therewith he drew the short-sword and hewed the head from Glam, and laid it at his thigh.
