Query: Not What You Might Expect

I bought this book expecting to read about how the FBI investigated Robert Hannsen, as well as the "cloak and dagger" aspects like the tradecraft he used and his interactions with his KGB handlers.Instead I found that about half of the book is about Louis Freeh and his ascention to the Directorship, and his accomplishments and failures along the way.Don't waste your money, borrow it from the library.
