The story started when I was listening to the tune Nerja played by Dave Roach on Landscape TV. The video with the music was of a light plane flying over Manchester; I thought what a great idea for a story if the plane vanished in front of all those witnesses but nobody knew what happened.
I started the story and before long -- as with many stories -- the plot skipped and the story came out as something very different to my intention, the venue had changed to the Canadian ice fields and taken on a new Native American spiritual theme. The book is my second best selling book on Amazon.
After putting the book on Amazon, I found that Nerja is a section of Spain which was fought over in the Peninsular War http://en.wikipedia.org/wiki/Peninsular_War
Further research revealed the man under the Duke of Wellington was one William Beresford.
The name Beresford gave me the link to Agatha Christie, my friend Sarah Meek and I have a long running in-joke between us where we refer to each other as Tommy & Tuppence and as any Christie fan will tell you, the Beresford brother and sister team featured in few of her stories; but remain my favourites.
