You are opening a book that tells a story of cruelty, heroism and betrayal in an original manner and without cliches. It is a story that has all the attributes of an ancient tragedy. It involves a blood-thirsty dictator, courageous avengers as well as a vile traitor. Yet an insuperable abyss separates it from ancient tragedy. The story of the assassination of the Deputy Reich Protector Reinhard Heydrich is not the work of a Greek dramatist. It is a story written by life itself. And the thousands of dead Czech patriots are real indeed.
