No telling exactly how it should be written. The place is identified as Seno de Skyring on most maps of Chile. I'm not sure what will happen to the title or the justification of it should I press ahead with this. In reality the action set there could probably not happen. I think Dad was basing his research on a book called The Uttermost Place on Earth (or something close to that). By the mid 20th century that area, while still remote was far from unpopulated, which is somewhat of a requirement for this story. You can get a ship into Seno de Skyring, but I don't think you can do it unnoticed!
