“Turns the long history of the FBI into a story that is as compelling, and important, as today’s headlines.”—Jeffrey Toobin, author of American Heiress

NATIONAL BESTSELLER • Named One of the Best Books of the Year by The Washington Post, New York Daily News, and Slate

Enemies is the first definitive history of the FBI’s secret intelligence operations, from an author whose work on the Pentagon and the CIA won him the Pulitzer Prize and the National Book Award.

We think of the FBI as America’s police force. But secret intelligence is the Bureau’s first and foremost mission. Enemies is the story of how presidents have used the FBI as the most formidable intelligence force in American history.

Here is the hidden history of America’s hundred-year war on terror. The FBI has fought against terrorists, spies, anyone it deemed subversive—and sometimes American presidents. The FBI’s secret intelligence and surveillance techniques have created a tug-of-war between protecting national security and infringing upon civil liberties. It is a tension that strains the very fabric of a free republic.

Enemies is a research masterpiece.

Enemies reads like a thriller, but don’t let the heart-pumping prose fool you.

Zegart, Ph.D., Stanford University, author of Spying Blind
 
“Tim Weiner’s Enemies is the most comprehensive history of the FBI as an intelligence agency we have ever had. Based on extensive research in previously unavailable materials, Weiner gives us a fresh way to think about J. Edgar Hoover, the many presidents he worked with, and the FBI as a national security agency. The book is also a cautionary tale that is essential reading for anyone concerned about American civil liberties.”—Robert Dallek, author of An Unfinished Life
