Many thanks to Carolyn Mays, my editor at Hodder & Stoughton, for her insightful and helpful comments on the manuscript. Also thanks to Abby Parsons and Thorne Ryan for all their assistance, and to Justine Taylor for her clear, thorough and reliable copy-editing. At McClelland & Stewart, I would like to thank Jared Bland and Kelly Joseph, and at William Morrow my editor Daniel Mallory and assistant editor Margaux Weisman. I would also like to thank my wife Sheila Halladay, who read the manuscript when I thought it was ready to submit and convinced me that it could be much improved.
Thanks to my agents Dominick Abel and David Grossman for their continuing encouragement and efforts. Also thanks to the invaluable publicists — Kerry Hood and Rosie Stephen at Hodder, Ashley Dunn at McClelland & Stewart and Julie Paulauski at William Morrow.
I would also like to thank Jenny Brierley, ICT Archivist at the West Yorkshire Archive Service, whose input is invaluable when it comes to cold cases and lost files.
Thanks again also to Nicholas Reckert for the interesting North Yorkshire walks that, despite their beauty, somehow always seem to suggest to me a possible crime scene.
Last but not least, thanks to the sales and marketing teams who work behind the scenes to make the deals and set up the special promotions, to the reps who get out on the road and sell the book to the shops, and to the booksellers themselves, without whom you wouldn’t be holding this volume in your hand. I would also like to add a special thank you to libraries everywhere. They are an endangered institution these days, and they deserve our support. And thanks, of course, to you, dear reader.
