Thanks to the staff at Nottingham Castle for the tour around the caves and especially to Pete Barnsdale who took us round the castle early in the morning before the crowds arrived. Ditto to the people at Sherwood Forest Visitors Centre and Rufford Abbey Country Park, plus thanks to Nottingham County Council for the use of the quote at the beginning of this book. Thank you to David Bamford for the help with checking historical details. Thanks to my friends and family for all their support not just while writing this, but during the last twelve years as I’ve been making my way in the writing biz. A special thanks to John B. Ford who gave me that all important first break and has been encouraging me ever since. A huge thank you to Jonathan Oliver who saw the potential of the idea, and Mark Harrison for bringing my protagonist to life. Thanks to Simon Spurrier for letting me play in his sandpit, and to Scott Andrews and Jaspre Bark for the opportunity of being part of something bigger than the whole.
