"With A Drop of Treason, Jonathan Stevenson does more than give us a readable, much-needed biography of Philip Agee's wild life, taking us from the lawns of Notre Dame to the streets of Hamburg and the plazas of Havana. By placing Agee's life in the context of the transatlantic left, he illuminates an often-overlooked facet of the Cold War with cloak-and-dagger elan and historical sweep."-- "Clay Risen, author of 'The Crowded Hour: Theodore Roosevelt, the Rough Riders and the Dawn of the American Century'"
