The name of the author of this book is a pseudonym. The text was based on the declarations of Hugo Walter García Rivas, an intelligence officer who requested leave and later deserted the Army’s Compañía de Contrainformación e Inteligencia (Company of Counterinformation and Intelligence). He made his first public declarations in Brazil in June 1980, providing information about the systematic and generalised use of torture, military intelligence operations, and names of repressors who were responsible for kidnapping operations. This testimonial material- along with information on political repression- provides details about how the armed forces used its influence to organise criminal networks for the trafficking of people, spying on ambassadors and people who did not conform to the dictatorship, as well as acts of repressive coordination against foreign agents.
