"Ku Klux Klan Secrets Exposed: Attitude toward Jews, Catholics, Foreigners and Masons. Fraudulent Methods Used. Atrocities Committed in Name of Order" by Ezra A. Cook Cook was known for his exposes, and his tackling of the Ku Klux Klan, one of the darkest societies in American history, is perhaps the best example of that. Between the 1880s and the 1900s, the group went through multiple types of public perception. This book exposes those perceptions as well as the ways in which its members managed to commit their acts without widespread public outcry.
