Many thanks to my wonderful family, Adam, Ruby, and Ben, for the constant flow of hot tea and encouragement to get this book completed.

Huge gratitude is also due to the team that made the jigsaw fit together so beautifully: Alice Cannan, Deirdre Rooney, Helen McTeer and Anna Osborn. As ever, enormous thanks go to Catie Ziller for trusting me with this challenging but ultimately hugely rewarding project.
