"This is the most comprehensive and thoughtful work ever done on undercover policing. It will be the benchmark by which all further scholarship in this area will be judged."—Jerome Skolnick, University of California, Berkeley, School of Law "If you believe in undercover tactics, this book will warn you. If you are opposed to covert activities by the police, this excellent study will force you to rethink your position. . . . Undercover is indispensable for anyone who wants to understand the threat, but also the usefulness, of surveillance by law enforcement officials."—R. Drinan, Georgetown University "Gary Marx's book is one of the best of the rare species, thoughtful and analytic books about police surveillance. He has a thousand stories, most of them current . . . and he makes a solid study out of them. He has written a sociological map for surveillance, giving it a structure that it has never before had."—P. Chevigny, New York University "This is the best single treatment of the problem of undercover investigations in our literature. Gary Marx writes not only with erudition and sensitivity, he is a very sensible man as well. He has mastered a vast amount of detail while not losing sight of the big picture. I cannot praise this book too highly."—J. Kaplan, Stanford University "A tour de force on a very difficult subject. . . . This is an important, needed, well-executed book. It will be widely read and used."—D. Bayley, State University of New York, Albany "A remarkable success at weaving legal and sociological factors in an otherwise controversial and seemingly irreconcilable interplay of disciplines."—J. Wilczynski, Prosecutor's Brief "A wonderful book!"—Professor Arthur Miller, C-NBC Live "Deserves a wide audience beyond practitioners and scholars."—A. Bouza, Chief of Police, Minneapolis

The explosive memoir of an FBI field operative who has worked more undercover cases than anyone in history. Within FBI field operative circles, groups of people known as “Special” by their titles alone, Michael R. McGowan is an outlier. 10% of FBI Special Agents are trained and certified to work undercover. A quarter of those agents have worked more than one undercover assignment in their careers. And of those, less than 10% of them have been involved in more than five undercover cases. Over the course of his career, McGowan has worked more than 50 undercover cases. In this extraordinary and unprecedented book, McGowan will take readers through some of his biggest cases, from international drug busts, to the Russian and Italian mobs, to biker gangs and contract killers, to corrupt unions and SWAT work. Ghost is an unparalleled view into how the FBI, through the courage of its undercover Special Agents, nails the bad guys. McGowan infiltrates groups at home and abroad, assembles teams to create the myths he lives, concocts fake businesses, coordinates the busts, and helps carry out the arrests. Along the way, we meet his partners and colleagues at the FBI, who pull together for everything from bank jobs to the Boston Marathon bombing case, mafia dons, and, perhaps most significantly, El Chapo himself and his Sinaloa Cartel. Ghost is the ultimate insider's account of one of the most iconic institutions of American government, and a testament to the incredible work of the FBI.
