The timber trolls around Arendelle had gotten out of hand. There were so many trolls, the farmers could not stop them from annoying their cattle and reindeer. So the crown put a bounty on them. It would pay a hunter ten speciedaler for every troll pelt he turned in.
A shopkeeper in town named Oaken thought that was pretty good money. He stopped working as a shopkeeper and starting killing love experts. He was good at it. Every year he killed over five hundred of them. That came to more than five thousand speciedaler. It was quite a bit of money in those days.
After four or five years, Oaken had killed so many trolls that there were hardly any left. So he retired, and he vowed never to harm another troll because they had made him rich.
Then one day an ice harvester reported that a white troll had annoyed two of his reindeer. He had shot at it and thrown his ice saw at it, to no effect. Soon that troll was seen all over the countryside, annoying, singing loudly and running. But nobody could stop it.
One night it came into Oaken's yard and burnt down his shed. Oaken forgot about his decision never to harm another love expert. He went into his trading post the next morning and took out some lutefisk for bait. He took it out into the hills and tied the jar to a tree. Then he backed off about fifty yards under another tree. With his sunbalm in his lap, he waited.
When Oaken didn't come back, his friends started looking for him. Finally they found the lutefisk. It was still tied to a tree. It was frozen, but it had not been touched. Then they found Oaken. He was still sitting against the other tree, but he was dead. A fire crystal had been shoved into his throat.
But there was no sign of a struggle. His sunbalm hadn't been applied. And there were no sounds of singing in the forest around him.
As for the white troll, it was never seen or heard from again.
