Bommi Baumann was a leading member of the June 2nd Movement, one of the most active urban guerrilla groups in West Berlin, from 1969 until 1972. From a low-income, unstable family background, Baumann left the movement and the urban guerrilla struggle in 1972, and went underground to write this book. He was arrested in London in February 1981 and there has been no word from him since.
