Accompanying her parents to Berlin in the 1930s, Martha Dodd knew almost nothing about Adolf Hitler or the Nazis. Yet almost overnight, she stepped into the spotlight, and found herself at the over-heated centre of Hitler's 'New Germany', befriending and dating several high-ranking Nazis, including the then-head of the Gestapo.

An affair with a dashing Russian diplomat saw her recruited as a spy, and so began a long and tumultuous career in both Berlin and America, including infiltrating First Lady Eleanor Rooevelt's inner circle and playing a key role in Henry Wallace's disastrous 1948 presidential campaign.

Betrayed by a Hollywood-hustler-turned-double-agent, Martha spent years under deep FBI surveillance - escaping twice - and went to ground in Cold War Prague, sad, lonely, rich and bored, living out her final decades in a Communist Sunset Boulevard.

Largely forgotten, Martha Dodd began emerging as an iconic historical figure in the early 2000s. While her scandalous behaviour and pro-Soviet leanings were never much in dispute, the actual matter of her guilt remained unresolved. Using recently released KGB archived information and FBI files, in Traitor's Odyssey, author and journalist Brendan McNally corrects this, telling the full epic of Martha Dodd's life for the first time, casting her in a new and bright light.
