The Laxdaela Saga, tr. by Muriel Press, [1899], at sacred-texts.com
The tale is told of Hrapp that he became most violent in his behaviour, and did his neighbours such harm that they could hardly hold their own against him. But from the time that Olaf grew up Hrapp got no hold of Thord. Hrapp had the same temper, but his powers waned, in that old age was fast coming upon him, so that he had to lie in bed. Hrapp called Vigdis, his wife, to him, and said, "I have never been of ailing health in life," said he, "and it is therefore most likely that this illness will put an end to our life together. Now, when I am dead, I wish my grave to be dug in the doorway of my fire hall, and that I be put thereinto, standing there in the doorway; then I shall be able to keep a more searching eye on my dwelling."
After that Hrapp died, and all was done as he said, for Vigdis did not dare do otherwise. And as evil as he had been to deal with in his life, just so he was by a great deal more when he was dead, for he walked again a great deal after he was dead. People said that he killed most of his servants in his ghostly appearances. He caused a great deal of trouble to those who lived near, and the house of Hrappstead became deserted. Vigdis, Hrapp's wife, betook herself west to Thorstein Swart, her brother. He took her and her goods in. And now things went as before, in that men went to find Hoskuld, and told him all the troubles that Hrapp was doing to them, and asked him to do something to put an end to this. Hoskuld said this should be done, and he went with some men to Hrappstead, and has Hrapp dug up, and taken away to a place near to which cattle were least likely to roam or men to go about. After that Hrapp's walkings- again abated somewhat. Sumarlid, Hrapp's son, inherited all Hrapp's wealth, which was both great and goodly. Sumarlid set up household at Hrappstead the next spring; but after he had kept house there for a little time he was seized of frenzy, and died shortly afterwards. Now it was the turn of his mother, Vigdis, to take there alone all this wealth; but as she would not go to the estate of Hrappstead, Thorstein Swart took all the wealth to himself to take care of. Thorstein was by then rather old, though still one of the most healthy and hearty of men.
