We now return to Grettir, who came from the eastern fjords, travelling in disguise and hiding his head because he did not wish to meet Thorir. That summer he spent in Modrudal Heath and other places. For a time too he was on Reykja Heath. Thorir heard of his being on Reykja Heath, gathered his men and rode thither, determined not to let him escape. Grettir scarcely knew of their plans before they came upon him. He was in a hill-dairy a little off the road with another man, and when they saw the troop they had to lay their plans quickly. Grettir said they should make their horses lie down inside the house, and they did so. Thorir rode forward across the heath in a northerly direction, missed the place, did not find Grettir and turned back home. When the troop had ridden round to the West, Grettir said: "They will not be pleased with their expedition if they do not meet me. You stay and mind the horses while I go after them. It would be a good jest if they did not recognise me."

His companion tried to dissuade him, but he would go. He changed his dress, put on a wide hat which came down over his face and took a stick in his hand. Then he went along the road towards them. They addressed him and asked whether he had seen any men riding over the heath.

"I have seen the men whom you are seeking," he said, "you very nearly came upon them; they were on your left hand just south of the marshes."

On hearing this they galloped off towards the marshes, which were so swampy that they could not get through and had to spend a great part of the day dragging their horses out. They swore much at the supposed traveller for playing a practical joke upon them.

Grettir returned speedily home to his companion, and when they met spoke a verse:

They rode off as fast as they could westwards towards the homestead in Gard before Thorir could come there with his company. When they were near the place they met a man on the road who did not know them. There was a young woman standing outside, very much dressed up, and Grettir asked who she was. The man who had come up said she was Thorir's daughter. Then Grettir spoke a verse:

From this the man learnt who it was, and rode to the house to tell them that Grettir had come round. When Thorir returned many men thought that he had been bamboozled by Grettir. He then set spies to watch Grettir's movements. Grettir took the precaution of sending his companion to the western districts with his horse, while he himself went North into the mountains at the beginning of the winter, muffling up his face so that no one should recognise him. Every one thought that Thorir had fared no better but even worse than at their former encounter.
