Directorate S: The C.I.A. and America's Secret Wars in Afghanistan and Pakistan (Hardcover)

AUTHOR'S NOTE
Two extraordinary colleagues contributed deeply to this book. Christina Satkowski, who earned an undergraduate degree at Wellesley College and a master's degree at Georgetown University, carried out important interviews and document analysis for more than two years. She was singularly responsible for the rich interviews that inform chapter 26, among many contributions. I could not have finished the book without her. The same is true of Elizabeth Barber, a graduate of the honors college at the State University of New York who also earned a master's degree from Columbia University's Graduate School of Journalism. Among other things, Elizabeth carried out a nine- month fact-check of the manuscript, recontacting sources and reaching out to new ones. She used this reporting to improve the manuscript from start to end, adding new scenes and revelations, and pushing tirelessly for accuracy, nuance, and completeness. Although I am solely responsible for what appears in these pages, Directorate S belongs to Christina and Elizabeth as much as it does to me. There are other colleagues from Co- lumbia and elsewhere who made important contributions; I have tried to thank them all in the acknowledgments.
