Facts inspired and informed this story. The horrors of the prison hulks in Wallabout Bay, for example, have not been exaggerated. Historians estimate that as many as twelve thousand men died in them, more than twice the number of casualties suffered on the battlefield. I have endeavored to fit the fictional elements of this story into the realities of the time. On the occasions where the historical record varies, such as the date of celebration for the queen’s birthday, I chose to use the information that best suited the narrative. Any allowances I made were as minor as I could keep them, and done in the service of telling a story of a young woman who was a true patriot.

Rebel Spy is about a brave and intelligent young woman I greatly admire. I have been blessed to know many such women in my life, a few of whom were indispensable in the creation of this book.

Tina Dubois has been a constant champion of mine and Frannie’s from day one. Tina, your compassion and support have made all the difference. The “pipe scene” was for you. I am so fortunate you’re my agent; thank you for letting me daydream as I paced the shallows. Thanks also to Berni Barta and Tamara Kawar for your efforts on my behalf. I’m proud to be represented by an agency that attracts such good minds as yours. I’d be remiss if I didn’t also mention Roxane Edouard; thank you, Roxane, for everything you have done for me behind the scenes.

Kate Sullivan provided passionate and thoughtful editorial guidance as I wrote Rebel Spy, not to mention an abundance of patience and encouragement. Thank you so much, Kate, for loving 355 and giving me a chance to tell her story. Effusive thanks are also due to Wendy Loggia, who brought a new energy and perspective to the manuscript, along with a fresh wave of support. My gratitude also goes to Beverly Horowitz for her belief in this book, and to Alexandra Hightower, Audrey Ingerson, and Alison Romig for their help along the way.

The stunning cover for Rebel Spy was designed by the ridiculously talented Ray Shappell, with art provided by the equally talented artist Ze Otavio. I’m in love with it. Cheers to you both.

Colleen Fellingham, Heather Lockwood Hughes, and Alison Kolani helped pull a raw manuscript into publishable shape. So much work goes into editing, designing, and marketing books. Thank you, and everyone who’s been part of Rebel Spy’s journey at Delacorte, for your help.

Researching 355 and the American Revolution was an ongoing process that began in earnest nearly four years ago. Thank you, Tory Inloes, for your enthusiastic emails filled with references for me to explore. Thanks also to Nicole VanderMeer for your exhaustive and detailed research on my behalf; this story was informed and improved through your findings. JT Marcinkowski also helped me with organization and research; I’m rooting for you, JT!
