I have authored over twenty non-fiction books and since 2021 ghostwritten three major non-fiction titles for Penguin Random House, Little Brown and Pan Macmillan. This year I wrote The Costumes of Downton Abbey (Insight Editions) and previous books include Long Live the Queens (HarperCollins) and The World of Poldark (Pan Macmillan). I have also written several other popular history and lifestyle memoirs, devised and written gift books, and contributed to a variety of children’s books. I have also ghostwritten three memoirs for private clients, including a former professional cyclist, successful businessman and hotelier.
