I am always grateful to the men and women from the CIA who share their stories with me, and I assured everyone I would protect their privacy. As you might imagine, privacy is of the utmost importance to those working in the intelligence field. For this reason, all the names and identifying details have been changed, and the stories have been edited for clarity and to ensure they would be understandable to people who do not work in the intelligence field. In some instances, dates and/or geographical regions have been changed. Again, this was critical to do to ensure the privacy of everyone who joined me in this book.
