the gold bar you didn’t put on the scales is the counterfeit. Otherwise put the three bars that are lightest on the scales. Take two of these bars and put them on either side of the scales. If they balance, then the bar you didn’t put on the scales is the counterfeit. Otherwise, the lighter of the two bars is the counterfeit.

Special thanks to my publisher and editor, Ann-Janine Murtagh, for all her help and support during the many years of thinking about writing and actually writing this book. Few editors can be tougher than her and I am grateful for it. I am also very grateful to Adrian Darbishire and Rachel Folder for reading and rereading the text and talking through countless plot options and coming up with some really good ideas along the way. Thanks to Pete Lambert, Lucy Mackay and John Perella for discussing Ruby Redfort ad nauseam. Thank you to David Mackintosh for his beautiful and clever design work and to Nick Lake for his thorough and thoughtful editing. Last of all, thanks a whole heap to Trisha Krauss and Lucy Vanderbilt for advice on American-speak.
