As we approach the hundredth anniversary of Victor Serge’s classic exposé of political repression, the specter of fear as a tool of political repression is chillingly familiar to us in world increasingly threatened by totalitarianism. Serge’s exposé of the surveillance methods used by the Czarist police reads like a spy thriller. An irrepressible rebel, Serge wrote this manual for political activists, describing the structures of state repression and how to dodge them—including how to avoid being followed, what to do if arrested, and tips on securing correspondence. He also explains how such repression is ultimately ineffective.
