This book is a collection of short biographies of famous insane rulers. This includes a number of the European monarchs that due to genetic issues suffered from mental health issues that where not understood at the time, and they didn't have ways to help treat then. It also has the stories of dictators that just went crazy with power. It starts out with Caligula and ends with Kim Jong-Il. It was a very short book with only a couple pages for each person.
