NOW A MAJOR MOTION PICTURE starring Liam Neeson.

It was the biggest mystery of American history. A shadowy source deep within Washington had leaked crucial information to two journalists, helping them uncover the historical Watergate Scandal of 1972. But who was this elusive source and what were his motivations? Thirty-three years later, the FBI’s Mark Felt would finally identify himself as Deep Throat, the Watergate Whistleblower. This is his story.

Mark Felt learnt spy craft tracking Nazi and Soviet spies, tackled mobsters in Kansas City and took down the FBI’s most wanted list, rising through the ranks under J Edgar Hoover to one of the FBI’s top positions.

A life spent watching pivotal moments of history unfold, Mark Felt was the eyes and ears of the intelligence service. Drawing on his memoirs, FBI memos, secret files and conversations with his family and friends, this is the account of a G-Man’s life and his struggle for honour in Washington.

This new edition is updated with the help of Mark’s lawyer, John O’Connor, drawing on new developments and why now, the role of Deep Throat, is even more important than ever.
