What inspired you while writing Spies in the Sky?
I adopted a rescued pigeon around 10 years ago and while I was searching for a name, I came across a list of pigeons awarded the Dickin Medal for their service during World War Two. I knew pigeons had played a part in the war, but until then I was unaware of the National Pigeon Service or how many lives were saved by these remarkable birds. The more I looked into the history, the more fascinated I became. I wrote an article called ‘Feathered Heroes’ for The School Magazine, and I knew then that I would love to develop the ideas into a children’s book. So when my publisher asked for a follow-up book to The Reindeer and the Submarine, I suggested a story about World War Two pigeons. They loved the idea and Spies in the Sky was born.
