The Assassination of Heydrich

"Jan Wiener's fascinating, well-documented book tells of the heroic exploits of various Czech men and women, most of whom paid for their resistance with their lives. Above all it gives a detailed, documented account of the assassination of Reinhard Heydrich, the most gruesome of the Nazi murderers, by Czech resisters parachuted from London but aided in their task by the Czech underground."
William L. Shirer, author of The Rise and Fall of the Third Reich

If you only read one book about what it felt like to be present during the worst time in modern human history, a time when your life could be snuffed out for having the mere thought of opposition against the Nazi regime, this should be the book because it is told by survivors and by one of the greatest survivors of them all, Jan Wiener.
