Cate Paterson you are a legend! Thank you for rescuing me when I was drowning. Special thanks too to Mathilda Imlah for coming in at a late stage with wise and thoughtful suggestions and, as always, to Jo Jarrah for applying her forensic editing skills to get me out of trouble. And to all the staff at Pan Macmillan who work so hard to turn a story into a book and get it out there on the shelves. You are simply the best.
