This book contains the letters from Gabriel Russier (1937-1969), most of them written from prison. The introduction of the book tells the story of a love affair in the 1960s between the 30-year-old French teacher, Gabrielle Russier, and a student of 16, Christian Rossi. This affair, which was considered a scandal because the perpetrator was a woman, resulted in her persecution, imprisonment and finally in her suicide.
