Advise and Consent
by Allen Drury
This is all about the United States and it’s a novel based on the Alger Hiss/Whittaker Chambers hearings, but it fictionalises them beautifully. If you read this book and then you watch, in future, a hearing on the confirmation of a secretary of state or a supreme court judge, you will understand far better as a result of it how these things happen than you otherwise would.
