Fanatic. Murderer. Martyr. Karl-Ludwig Sand was all of these things and more. Alexandre Dumas delves into his fascinating story as part of the "Celebrated Crimes" series. Sand was a devout believer in German unification. At the time, Germany existed only as a loose confederation. In the name of this cause, he broke into the house of the conservative writer August von Kotzebue and stabbed him to death. Tried and executed in 1820, Sand became a nationalist icon. Dumas' depicts a man driven to extremes by radical ideas. It's a story that remains frighteningly relevant to this day.
