Some very generous people helped me research and write this novel, and I want to thank them. They include, for much help on cell phones and computer forensics, Jeff Fischbach; on mobile phone forensics, Tom Slovenski; on computer hacking, Adam Hernandez, and especially Kevin Ripa. On perimeter security, locks, and lock picking: Marc Weber Tobias and, once again, Jeff Dingle and Kevin Murray. On hotel security: Jeffrey Saunders of the Saunders Hotel Group, Jon Estabrook of the Lenox Hotel, Jim McGlynn of Engineering PLUS, and Fred Juran of Kaba.
Jay Groob of American Investigative Services was again extremely helpful, as were Dick Rogers, Jack Hoban, Matthew Fleming; and Sean Murphy of The Boston Globe. In DC, my thanks to Kenneth Cummins of the Capitol Group, Robert “Buzz” Glover of the MPD, and especially James Trainum.
On gossip websites: Ben McGrath of The New Yorker and Gaby Darbyshire. For help with ecclesiastical Latin, thanks to Dr. William L. Daniel and Matt C. Abbott. I had legal assistance from Martin Garbus and, once again, Jay Shapiro of White and Williams; big thanks to the brilliant jurist Leo Katz of the University of Pennsylvania Law School for advice on mens rea. Clair Lamb was, as always, invaluable in all sorts of ways, including DC research; thanks as well to Karen Louie-Joyce; and to my good friend Rick Weissbourd, Stanford ’79.
My thanks for the loving support of my wife, Michele Souda, and our daughter, Emma J. S. Finder. At Dutton, I’m grateful to Amanda Walker, Carrie Swetonic, Jess Renheim, and especially Ben Sevier.
