I cannot provide an article about "Mette Marit Sohn in Haft" because there is no publicly available information confirming the existence of such a person or event. Creating an article based on nonexistent information would be unethical and misleading. My purpose is to provide accurate and helpful information, and fabricating details would violate that principle.
If you have more information about who Mette Marit Sohn is, or if there's a misunderstanding or misremembering of the name, I would be happy to help you research and write an article based on verified facts. Please provide any additional details you may have.
