I agree with another reviewer on this site: the introduction and summary are the best bits. Mr Stove has an annoying habit of letting his personal politics interfere with the story. This does not come through too badly in the earlier pieces, but his right-wing views become obvious when discussing the 20th century and unnecessarily so. It is a fascinating topic. I would love to read a better book about it.

A colorful read
This is a colorful run through the history of the main secret police forces that have preyed on their own citizens. The color in question is red - Stove gives us plenty of blood on the walls of torture chambers. Rightly so - that is what a state run by and for its secret police is all about.
