My good friend, Scott F. Hill, PhD,
was once again one of my most invaluable assets in crafting this novel. His sharp mind is exceeded only by his warm friendship and deep sense of patriotism. Thank you for everything.James Ryan
(not his real name) operates in some of the darkest and most dangerous corners of the world. The things he shared with me during the writing of this novel made me incredibly grateful that our nation has such men and women of character, integrity, courage, and ability willing to make such exceptional sacrifices. If Mr. James Ryan ever shows up on your doorstep it is either the best day or the last day of your life. “TIA” my friend. Thank you and bless you for everything you have done for me on and off the field.Much of this novel has been influenced by the erudite writing, commentary, and courage of Robert Spencer,
who generously assisted me in my research. I am indeed honored to call him my friend. He suffered weekly telephone and email bombardments during my writing and research and always did so with brilliant responses and good humor. Robert, I am much obliged.One of the greatest rewards of my career has been getting to meet people whom I deeply respect and admire. As I have gotten older, I realize that outside my military, law enforcement, and intelligence contacts there aren’t many people who both “talk the talk” and “walk the walk” as well. Glenn Beck
is definitely one of those people. When you have a friend who sets the bar so high for himself, it is impossible not to constantly strive to raise your own even higher. Thank you for everything, my friend. You have been an inspiration.I am also incredibly fortunate to have a key group of warriors with whom I not only share ideas and frank debate, but also friendship. My novels wouldn’t be what they are without them. They inspire and guide my work not only by what they say, but also what they do. Each has contributed in too many ways to mention. They are: Tom Baker, Steven Bronson, Jeff Chudwin, Rodney Cox, Thomas Foreman, Chuck Fretwell, Frank Gallagher, Steve Hoffa, Mike Janich, Cynthia Longo, Ronald Moore, Mike Noell, Chad Norberg, Gary Penrith, Rob Pincus
and Mitch Shore-as well as all of my other brothers and sisters out there who asked that they not be named in this book for their own safety. Thank you for all you do for us. Stay safe.As I have said before, without the fabulous bookstores, online retailers,
and the Atria/Pocket sales staff, you wouldn’t be holding this in your hands right now. I am extremely grateful to all the people who have worked so hard to build me as an author and who strive to make every book more successful than the last. It is a team effort, and along with Jeanne Lee, the Atria/Pocket art and production departments, and the Simon amp; Schuster Audio family I couldn’t hope to be aligned with more creative, intelligent, and truly nice people in the publishing business.Daniel Pipes
consulted with me at the very beginning of the novel and I am quite grateful for his insight, generosity, and advice.Dr. Rusty Shackleford and his team
are a force to be reckoned with. Though few know who they really are, many know the incredibly dangerous and important work that they do every day. Thank you for everything.Thanks as well goes to Anna Berkes,
Research Librarian at Thomas Jefferson’s Monticello; Anna McAlpine, Director, Public Relations amp; Marketing at Thomas Jefferson’s Poplar Forest; and Clark Evans of the Library of Congress.In Washington, D.C., I am grateful for the assistance of my friends David Vennett, Patrick Doak,
and my new Beltway “insider,” Tim Holland.I also want to thank Richard and Anne Levy
for their help as well as that of our shared foreign intelligence asset, Alice.The continued help and support of two of my best sharpshooters, Tom and Geri Whowell,
is also deeply appreciated.Thanks as well go to Danielle Boudreau
of Bombardier Business Aircraft, the United States Park Service, and the DC Metropolitan Police Department.I am exceptionally fortunate to be on a powerhouse publishing team surrounded by brilliant people. That team is led by the incomparable Carolyn Reidy.
As our professional relationship has grown, so too has our friendship. Carolyn, it is both an honor and a pleasure working with you.
