Martha Dodd was an American spy for the Soviet Union who spent her final decades in Prague. Dodd’s colourful life, and grim end, are the subject of the book Traitor’s Odyssey by Brendan McNally, a US journalist who himself lived in the Czech capital in the 1990s. And, as he explains, McNally first heard of the story of Martha Dodd from a woman who worked for Radio Prague International in the depths of the Cold War era.
