Whoever coined the term “difficult second novel” was entirely correct, and whoever coined the term “difficult third novel” was even more correct (but that’s a story for another time). I thought a lot of people had influenced Guess Who, but that was nothing compared to Now You See Me. For starters, I would like to thank everyone at the Standedge Visitor Centre and the pilots who took me through the incredibly impressive and equally eerie Standedge canal tunnel. Sorry I didn’t tell anyone what I was up to! I hope I have written a novel that compliments the legacy of the tunnel more than tarnishes it. As always, I’d like to thank my #SauvLife crew, Fran Dorricott, Jennifer Lewin and Lizzie Curle, for giving me support whenever I needed it, and a digital WhatsApp shoulder to cry on when things went wrong. Ever since the launch of Guess Who, I’ve found a wonderful home at Waterstones Durham Crime Club and met many authors and readers, who have inspired me and I now consider firm friends. These people include the wonderful Fiona Sharp, who I met completely by chance whilst going in to buy a book and I’m convinced has now become the reason for over 70 percent of my book sales, Daniel Stubbings, who beta-read this book and provided really encouraging and honest feedback when I was feeling down on it, Claire Johnson and Dave Dawe, for words of kindness and encouragement, Liam, Not Andy, Mick, Helen, fellow authors Robert Scragg and Judith O’Reilly and everyone else from the group, whose passion for crime fiction really inspires me to keep going and make every book the best it can be. To my MA Creative Writing colleagues who have helped me through the early stages of my writing. To Claire McGowan and A. K. Benedict, who I could never have got to this stage without. To my wonderful agent, Hannah Sheppard, who is always a joy, and is always on the other end of the phone when I need to chat. To my fabulous UK editor, Francesca Pathak, who believed in this book from the very beginning, and to the rest of the team at Orion—you’re all fantastic. I would also like to thank the team at Hanover Square Press, including Peter Joseph, Natalie Hallak and everyone who helped bring this book to your hands. And finally, to you, the reader. I hope it’s been an enjoyable ride. See you next time!
