Acknowledgements
I am grateful to the late Felicity Bryan, whose interest and enthusiasm helped to shape this project in its earliest stages. My current agent Carrie Plitt provided valuable help during the later stages of work on it.
My thanks to Arabella Pike and her team at William Collins, including Sam Harding and Alex Gingell.
Christopher Hollings read the book in draft, as did my parents Moira and Tony Wardhaugh; their comments and suggestions were of great value.
As always my greatest debt is to my wife Jessica and our three sons, whose support, advice and practical assistance at all stages of this project were invaluable.
