Colin Castle was born and educated in the UK. He lives with his wife Valerie in Kelowna, where he taught high school history for thirty years. During that time he came to know alex Jardine because both men had married Johnston wives. For a World War II schoolboy aircraft-spotter, with his own Service experience, and who had taught the history which Alex lived, the task of writing this story had instant appeal. When he retired from the classroom in 1998 he had the time to do it. Castle expects to write further books.
