After 35 minutes of being tossed around by high-velocity winds since leaving Aberdeen, the Fairchild 340 touches down at Kirkwall airport. I zip up my windcheater and turn up its collar against the rain as I disembark. I have arrived in Orkney, the 70-island archipelago that lies beyond the farthest tip of the Scottish mainland. It is early October, and I am here to research my new book, The Secret of the Druids, which is set in the UK, with plans to tour the Mainland the largest island in the group and its neighbour, Rousay.
