The book tells the story of Vivien Spitz, who worked as a stenographer at the Nuremberg trials from 1946 to 1947. This trial was the first international criminal proceeding in history that exposed the atrocities committed in Nazi Germany. The book describes in detail the experiments of twenty doctors and three of their assistants, who tried out— and killed—people in the name of medical research. Each chapter focuses on one experiment and includes transcripts of court sessions that were previously unavailable to the general public.
