Riveting… Delving into the circumstances that primed the American public to believe that shadowy élites at the heart of the federal government were conspiring against them, Tinline traces how the report helped fuel various conspiracy theories over the coming decades.

New Yorker

Phil Tinline's startling book about the weird legacy of a brilliant anti-war hoax is not just an illuminating deep dive into offbeat history. It is an essential read for anyone trying to understand the tragicomic nature of contemporary politics. Itself both hilarious and profoundly serious, it helps us grasp how laughter has turned so deadly.

An excellent new book…Tinline's fast-paced account is often entertaining but never loses sight of where it is heading: toward a moment, our own, when conspiracists and crackpots have seized the levers of power….Both important and unsettling.

New York Times

Astonishing, important, and beautifully told…[shows] that distrust of the federal government and the belief that a shadowy cabal of evil elites is somehow in charge-ideas that powered the rise of U.S. President Donald Trump-have roots that reach back more than half a century.

Foreign Affairs

Eye popping…Tinline's account is both convincing and horrifying.

Daily Telegraph

Remarkable…Ghosts of Iron Mountain is a potent reminder that hard facts have rarely been enough when powerful satire feels more truthful.
