Reporter, by Seymour Hersh, is a mostly serious look at the role of journalists, the years when Vietnam and Watergate dominated the news, the tension that has always existed between the powerful and those who write about them, the importance of questioning authority, and the fact that cover-ups and lies by the powerful have been around for decades.
But there are humorous moments:
"As we got settled [around the pool], I saw a young woman reading my book [about Henry Kissinger] while sunbathing. Thirty minutes later she was fast asleep, with the opened book shielding her face from the sun."
Ah, the glamorous life of a writer!
