When I first read this 1974 novel, set in West Germany around the time of the Red Army Faction, it seemed very foreign to me in every sense. A serious terrorist threat? Law enforcement overreach to deal with it? Powerful, sensationalist right-wing media whipping up the panic? Well, times have changed, and the resonances today are different for American readers. I discovered as much earlier this year, when Penguin asked me to write an introduction for this new paperback edition.
