If you're a history buff, you know about J. Edgar Hoover. He was likely the most powerful man in the US. If you start reading about him, the books contradict each other constantly. I was often left with very little sense of the man personally. I had a sense of what he did and didn't do and what people disagreed about whether he did this or didn't do this or that, but I was like, "Why? Why was he doing all of this?" That was my big question.
