Taking readers on a global journey through human history, Natasha Tidd examines how lies can change the world around us, from Julius Caesar’s deceptive PR machine to the cover-ups that caused Chernobyl.

From forgeries that created centuries worth of conflict and domination, such as The Donation of Constantine, the Protocols of Zion and the mysterious Testament of Peter the Great, to mass political and press cover-ups including Britain’s Boer War concentration camps, a Pulitzer Prize-winning whitewash of the Ukraine Famine and the infamous Dreyfus Affair in France.

Meet incredible people, including Jeanne de Clisson who became the fourteenth century's most feared pirate – all because of a lie.
