Dive into the electrifying tale of a Brooklyn-born patriot turned radical activist, in an era when America was torn by its ideological extremes

In the shadow of recent turmoil, Join the Conspiracy transports readers to a pivotal moment of division and dissent in American history: the late 1960s. Against the backdrop of the Vietnam War and a nation grappling with internal conflict, this compelling narrative follows the life of George Demmerle, a factory worker whose political odyssey encapsulates the era's tumultuous spirit. From his roots as a concerned citizen wary of his country's leftward tilt, Demmerle's journey takes a dramatic turn as he delves into the heart of radical activism.

Participating in iconic protests from the March on Washington to the Democratic National Convention in Chicago, Demmerle's story is a whirlwind of political fervor, embodying the struggle against what was perceived as imperialist war and racial injustice. His transformation is marked by alliances with key figures of the time, including Abbie Hoffman, and an eventual leadership role within an East Coast Black Panther affiliate. Yet, beneath his radical veneer lies a secret: Demmerle is an FBI informant.

Join the Conspiracy reveals Demmerle's complex role in a society at war with itself, where his deepening involvement with the radical left and a bombing collective forces him to confront his loyalties. The narrative, enriched by a rare trove of period documents, candid photos taken from inside the radical movement, and underground art-more than a hundred of which are included in the book-not only charts Demmerle's saga but also reflects the broader story of a nation struggling to find its moral compass amidst chaos.

As Demmerle navigates the dangerous waters of political extremism, readers are invited to ponder the price of ideology, the nature of loyalty, and the fine line between activism and betrayal. This book is not just a recounting of historical events but a vibrant portrait of a man and a move­ment that sought to reshape America.

Industry Reviews
"Never heard of George Demmerle - aka, Prince Crazie? Well, so much the better. Here was a man at the center of a crazy place (the East Village) in a crazy time (the late Sixties), plotting a revolution - while secretly working as an FBI informant. Jonathan Butler recreates it all in vivid, cinematic detail, while adding a whole new chapter to the history of the American Left. Clear your calendar and buckle up for a wild ride." - Jonathan Mahler, Author of Ladies and Gentlemen, the Bronx Is Burning and a staff writer for the New York Times Magazine "A story so wild it had to be true. Butler has unearthed an important slice of history and presented it with smarts and style. Like all the best history books, this one will help you understand the present as well as the past, and probably the future." - Jonathan Eig, King: A Life "Delving deep into a hidden history, Jonathan Butler relates an extraordinary drama with betrayal at its heart. Deeply researched and beautifully written, this previously unknown story set in the passionate, violent politics of the 1960s, stands with Conrad's The Secret Agent." - Andrew Cockburn, Washington Editor, Harper's Magazine "During the late 1960s, opposition to a half-million troops being in Vietnam, and to virulent racism and cultural conformity at home, morphed from a mass movement into a frenzied effort by some to tear down and rebuild society - violently if needed. Jonathan Butler's Join the Conspiracy ably sifts through that increasingly chaotic time by centering on an FBI-enabled infiltrator and the all-in radicals he both befriended and betrayed. The result is a new perspective about a country at war with itself, and about those who were willing to consume themselves in struggle." - Abe Peck, author of Uncovering the Sixties: The Life and Times of the Underground Press
