Heartfelt thanks to everyone who helped to make this book possible: to my family for support, childminding and somewhat baffled encouragement; to Kevin for handling all the tedious paperwork; to Anouchka for the loan of Pantoufle. Thanks also to my indomitable agent Serafina Clarke and editor Francesca Liversidge, to Jennifer Luithlen and Lora Fountain, plus everyone at Doubleday who helped to make me so welcome. Finally, special thanks to fellow author Christopher Fowler for turning on the lights.
