The spirit of a dead man asked a fisherman to take three messages to people he had wronged.
One night James Dempster, who lived in Tresta in Fetlar in the 19th century, went to the craigs [rocks] to catch fish, which he took home and gutted. When he went to the midden with the fish guts there was a man standing there. He recognised the man as someone who had just been buried the week before.
The man confessed that he had done things that were bothering him and he could not rest. He explained that he had come to Dempster as a man of good nerve. He asked Dempster three questions, which he answered correctly, proving himself fit to take a message. He was to tell a girl and her parents that the dead man was the father of the girl's child; he was to tell an old woman that the dead man had stolen and eaten her hogg [sheep]. The dead man was also bothered about saving driftwood on the sand, and Dempster was to ask the minister to offer up a prayer for him. If Dempster did not do these things, the ghost would be back. Dempster took the messages and never saw the spirit again.
Jeemsie Laurenson heard the story, which he called 'Dempster and the Spirit', from Willa May Brown, one of the greatest storytellers Fetlar has ever produced.
In other tellings of the story, it is made clear that the dead man had collected driftwood on a Sunday, breaking the Sabbath.
