A Threat of the First Magnitude tells the untold story of the FBI informants who penetrated the upper reaches of organizations such as the Communist Party, USA, the Black Panther Party, the Revolutionary Union and other groups labeled threats to the internal security of the United States.


Praise for A Threat of the First Magnitude:

“… Leonard and Gallagher turn a welcome spotlight on the informants who infiltrated deeply and likely illegally into radical political groups.” – Scott Martelle, author of Blood Passion: The Ludlow Massacre and Class War in the American West


“…a fascinating history that is also a prescient warning. After reading this book, I can’t help but wonder how things might have turned out if the government’s informants had never been members of the groups they helped destroy.” – Ron Jacobs, author of The Way the Wind Blew: A History of the Weather Underground
