This is chapter 4 of Grettir's saga, written by Allen French. Grettir's saga is one of the most famous sagas told in Iceland, which supposedly took place between the ninth and the eleventh centuries in Iceland and Norway. In chapter 4, the story of chief Thorhal and his misery is told. His land is haunted by ghosts and terrorised by a troll, which cause much damage to his livestock and people. Many people fled form his farm, because they were afraid to lose their lives, if they would stay there much longer. Everything becomes even worse when Glam, a new shepherd, joins their farm. By the night before Christmas, he got slayed and from that time on his ghost started haunting the land terribly. When all hope was lost, Grettir, who returned to Iceland recently, heard of the matter and offered his help, not knowing that this challenge might be the greatest he ever faced.
