I've read a lot of books about the deportation and life in the concentration camps; but never against the Nazi experiments on prisoners. This book is not extremely searched, but it provides a good approach to these barbarities as approaches each doctor Reich with its field of own experimentation. I struggled at times, it is at the limit of the unbearable ... It is nevertheless necessary to know these dark times in history for the duty to remember ... But how to believe in the human being after such horrors, especially from doctors? Michel Cymes makes a tribute to all the victims.
