Medical experiments on humans in concentration camps.
This book shows the medical experiments that Hitler and Himmler ordered or approved. The author is not a doctor, but a journalist. He searched for and found former inmates who had been experimented on by German doctors, captured doctors who, under the threat of death, had to serve as assistants or specialists to Nazi researchers.
Aristotel noted that "art imitates life" but it turned out that "life imitates art" can also be the other way around, as in the case of the novel The First, Second, Third Man by Mirjana Đurđević.
