"Now," said Thorhall, "I will give you a horse in exchange for that you have lost. You had better ride home to Biarg at once."
"Not at all. My horse has been killed, and I must avenge it." So Grettir remained.
Night set in. Grettir ate a hearty supper, and was right merry. But not so Thorhall, who had his misgivings. At bed-time the latter crept into a locked bedstead beside the hall; but Grettir said he would not go into a bed, he would lie by the fire in the hall. So he wrapped himself up in a long fur cloak and flung himself on a bench, with his feet against the posts of the high seat. The fur cloak was over his head, and he kept an opening through which he could look out.
There was a fire burning on the hearth, a smouldering heap of glowing embers, and by the red light Grettir looked up at the rafters of the blackened roof. The smoke escaped by a louvre in the middle. The wind whistled mournfully. The windows high up were covered with parchment, and admitted now and then a sickly yellow glare from the full moon, which, however, shone in through the smoke hole, silvering the rising smoke. A dog began to bark, then bay at the moon. Then the cat, which had been sitting demurely watching the fire, stood up with raised back and bristling tail, and darted behind some chests. The hall-door was in a sad plight. It had been so torn by Glam that it had to be patched up with wattles. Soothingly the river 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.
Then suddenly he heard something that shook all the sleep out of him, had any been stealing over his eyes. He heard a heavy tread, beneath which the snow crackled. Every footfall went straight to Grettir's heart. A crash on the turf overhead. The strange visitant had scrambled on the roof, and was walking over that. The roofs of the houses in Iceland are of turf. For a moment the chimney gap was completely darkened—the monster was looking down it—the flash of the red fire illumined the horrible face with its lack-lustre eyes. Then the moon shone in again, and the heavy tramp of Glam was heard as he walked to the other end of the hall. A thud—he had leaped down.
Then Grettir heard his steps passing to the back of the house, then the snapping of wood showed that Glam was destroying some of the outhouse doors. Presently the tread was heard again approaching the house, and this time the main entrance. Grettir thought he could distinguish a pair of great hands thrust in over the broken door. In another moment he heard a loud snap—a long plank had been torn out of place, and the light of the moon shone in where the gap had been made. Then Glam began to unrip the wattles.
There was a cross-beam to the door, acting as bolt. Against the gray light Grettir saw a huge black arm thrust in trying to remove the bar. It was done, and then all the broken door was driven in and went down on the floor in shivers. Now Grettir could see a tall dark figure, almost naked, with wild locks of hair about the head standing in the doorway. That was but for a minute, and then Glam came in stealthily; he entered the hall and was illumined by the firelight. The figure Grettir now saw was unlike anything he had seen before. A few rags hung from the shoulders and waist, the long wolf-gray hair was matted. The eyes were staring and strange. Grettir could hear Thorhall within his locked bed trembling and breathing fast.
Presently Glam's eyes rested on the shaggy bundle by the high seat. He stepped towards it, and Grettir felt him groping about him. Then Glam laid hold of one end of the fur cloak and began to pull at it. The cloak did not come away. Another jerk. Grettir kept his feet firmly pressed against the posts, so that the fur was not pulled away. Glam seemed puzzled; he went to the other end of the bundle and began to pull at that. Grettir held to the bench, so that he was not moved himself, but the fur cloak was torn in half, and the strange visitant staggered back holding the portion in his hand wonderingly before his eyes. Before he could recover from his surprise, Grettir started to his feet, bent his body, flung his arms round Glam, and driving his head into the breast of the visitor, tried to bend him backward and so snap his spine. This was in vain, the cold hands grasped Grettir's arms and tore them from their hold. Grettir clasped them again about his body, and then Glam threw his also round Grettir, and they began to wrestle. Grettir saw that Glam was trying to drag him to the door, and he was sure that if he were got outside he would be at a disadvantage, and Glam would break his back. He therefore made a desperate effort not to be drawn forth. He clung to benches and posts, but the posts gave way, and the benches were torn from their places.
At each moment he was being dragged nearer to the door. Sharply twisting himself loose, Grettir flung his arms round a beam of the roof, for the hall was low. He was dragged off his feet at once. Glam clenched him about the waist, and tore at him to get him loose. Every tendon in Grettir's breast was strained; still he held on. The nails of Glam cut into his side like knives, then his hands gave way. He could endure the strain no longer, and Glam drew him towards the doorway, in so doing trampling over the broken fragments of the door, and the wattles that lay about. Grettir knew that the last chance was come for saving himself. Here, in the hall, he could hold to posts and beams, and so make some resistance; but outside he would have nothing to cling to, and strong though he was, his strength did not equal that of his opponent.
Now the door-posts were of stone, and the beam that had served as bolt went across the door, slid into a hollow on one side cut in the door-post, and was pulled across and fitted into another hollow in the other post. As the wrestlers neared the opening, Grettir planted both his feet against the stone posts, one against each, and put his arms round Glam. He had the enemy now at an advantage; but then, he merely held him, and could not hold him so for ever. He called to Thorhall, but Thorhall was too greatly frightened to leave his place of refuge.
