What killed him they did not know. But he haunted the farmhouse, riding the roof, kicking the sides with his heels, killing cattle and destroying all things. Then Grettir came that way, and he slept in the hall. At night the dead Glam came in, and Grettir arose, and to it they went, struggling and dashing the furniture to bits. Glam even dragged Grettir to the door, that he might slay him under the sky, and for all his force Grettir yielded ground. Then on the very threshold he suddenly gave way when Glam was pulling hardest, and they fell, Glam undermost. Then Grettir drew the short sword, "Kari's loom," that he had taken from a haunted grave, and stabbed the dead thing that had lived again. But, as Glam lay a-dying in the second death, the moon fell on his awful eyes, and Grettir saw the horror of them, and from that hour he could not endure to be in the dark, and he never dared to go alone. This was his death, for he had an evil companion who betrayed him to his enemies; but when they set on Grettir, though he was tired and sick of a wound, many died with him. No man died like Grettir the Strong, nor slew so many in his death. Besides those Sagas, there is the best of all, but the longest, "Njala" (pronounced "Nyoula"), the story of Burnt Njal. That is too long to sketch here, but it tells how, through the hard hearts and jealousy of women, ruin came at last on the gentle Gunnar, and the reckless Skarphedin of the axe, "The Ogress of War," and how Njal, the wisest, the most peaceful, the most righteous of men, was burned with all his house, and how that evil deed was avenged on the Burners of Kari.
