Minds of Winter: Ed O`Loughlin

It begins with a chance encounter at the top of the world.

Fay Morgan and Nelson Nilsson have each arrived in Inuvik, Canada - 120 miles north of the Arctic Circle - searching for answers about a family member: Nelson for his estranged older brother, Fay for her disappeared grandfather. They soon learn that these two men have an unexpected link - a hidden share in one of the greatest enduring mysteries of polar exploration.
