After a close shave with murder, life in the Arctic helped me overcome debilitating fear

Isolation in Greenland helped stop constant worrying about my daughter's safety

In recent years I've often felt on top of the world, but I also know what it's like to teeter on the edge of the precipice, unsure whether I could save myself. Six years ago, I was an author with two conspiracy thrillers under my belt; both were bestsellers in Denmark and my path as a writer seemed set. But a few short moments, out walking with my 11-year-old daughter on an ordinary summer's day, changed everything.

We would often take a stroll past an abandoned sawmill near our house - something we'd been doing all my daughter's life. Our house was built more than a century ago by the owner of the sawmill, and even though it didn't come with the house when we bought it, we would laugh about it being ours.
