There was a fire burning on the hearth, a smouldering heap of red embers; every now and then a twig flared up and crackled, giving Grettir glimpses of the rafters, as he lay with his eyes wandering among the mysteries of the smoke-blackened roof. The wind whistled softly overhead. The clerestory windows, covered with the amnion of sheep, admitted now and then a sickly yellow glare from the full moon, which, however, shot a beam of pure silver through the smoke-hole in the roof. A dog without began to howl; the cat, which had long been sitting demurely watching the fire, stood up with raised back and bristling tail, then darted behind some chests in a corner. The hall door was in a sad plight. It had been so riven by the spectre that it was made firm by wattles only, and the moon glinted athwart the crevices. Soothingly the river, not yet frozen over, prattled over its shingly bed as it swept round the knoll on which stood the farm. Grettir heard the breathing of the sleeping women in the adjoining chamber, and the sigh of the housewife as she turned in her bed. Click! click!--It is only the frozen turf on the roof cracking with the cold. The wind lulls completely. The night is very still without. Hark! a heavy tread, beneath which the snow yields. Every footfall goes straight to Grettir's heart. A crash on the turf overhead! By all the saints in paradise! The monster is treading on the roof. For one moment the chimney-gap is completely darkened: Glámr is looking down it; the flash of the red ash is reflected in the two lustreless eyes. Then the moon glances sweetly in once more, and the heavy tramp of Glámr is audibly moving towards the farther end of the hall. A thud--he has leaped down. Grettir feels the board at his back quivering, for Thorhall is awake and is trembling in his bed. The steps pass round to the back of the house, and then the snapping of the wood shows that the creature is destroying some of the outhouse doors. He tires of this apparently, for his footfall comes clear towards the main entrance to the hall. The moon is veiled behind a watery cloud, and by the uncertain glimmer Grettir fancies that he sees two dark hands thrust in above the door. His apprehensions are verified, for, with a loud snap, a long strip of panel breaks, and light is admitted. Snap--snap! another portion gives way, and the gap becomes larger. Then the wattles slip from their places, and a dark arm rips them out in bunches, and flings them away. There is a cross-beam to the door, holding a bolt which slides into a stone groove. Against the grey light, Grettir sees a huge black figure heaving itself over the bar. Crack! that has given way, and the rest of the door falls in shivers to the earth. "Oh, heavens above!" exclaims the bonder.
